This page lists [[YANI]]s that have been discussed on several NetHack-related IRC channels on [[Freenode]], so they don't end up ignored and forgotten.

Attribution will be listed whenever possible. I make no claim to any of the ideas. Feel free to add any other YANIs from IRC to this page, and to use or implement any of them as you see fit.

How these are retrieved: I log the #nethack, #nethack-dev, #hardfought, ##nethack-discord, ##nethack-variants, and #nethack4 channels. (If people are discussing YANIs on channels not listed here, let me know!) The logs are searched for strings like "yani", "yet another", and "feature request", with some surrounding context. Sometimes there's enough discussion of an idea to warrant more than a row in the table, and so it gets own section here.

Things that are ''not'' added to this page include:
* Variant developers (and only variant developers) talking about planned changes to their own variant. ''Possible'' changes to their own variant that are variant-agnostic are still fair game.
* [[Evil Patch Idea]]s.
* Ideas which are fully realized already in some variant or have been in previous versions of vanilla NetHack.
* Some YANIs for [[dNetHack]]-specific things that were suggested among an audience of dNetHack developers, because there are a lot of these and they tend to get recorded by the dNetHack developers quickly.
* YANIs by only me, which are [[User:Phol ende wodan/YANI|here]] instead.
* [[YASI]]s, which grew to be a long enough list that I moved them to [[User:Phol ende wodan/YANI/YASI|their own page]].

== Identification mechanics ==
''Contributions by ais523, FIQ, jonadab, aosdict''

The main idea here is to make the identification game less regimented. Currently, a rational player (who will not take the risks associated with direct use-ID) is restricted to indirect use-ID (and monster use-ID) of most objects until such time as they can find a general, book, or scroll shop, at which point they can price-ID the scroll of identify and other items. Once identify is known (and could be blessed), the good items (as determined by price ID) can be fully identified. This is problematic because it's not at all a gradual process, and it feels like it should be.

Some ideas have been floated to remove price ID outright (presumably, a shopkeeper would pay the same amount for each item of an object class as they currently do with amulets). This has some advantages; price ID is tedious, encourages stashing to some extent (because stashing near a shop where you can ID new things is good), and roguelike players who don't primarily play NetHack tend to hate its price ID system. In this case, either the scroll of identify should start out identified for all characters, so that identification doesn't take forever to get off the ground, or some other mechanic should be added so identify is easy to pick out for spoiled players.

If price ID is not to be changed, it should become less regimented and predictable, and less necessary of a strategy. The entire idea of price tiers doesn't appear to be based on anything much, and having items nicely organized into tiers makes it easy to disregard entire classes of items once their base prices are known. Ideas include:
* Change price ID so that each item is assigned to a "band" of possible prices. There are four price bands, and each item class has its base price randomized based on its band. The price bands show up on unidentified items, e.g. "an expensive scroll labeled KIRJE". Some items might fall into more than one price band.
* Fuzz the prices of items so that it's not possible to definitively say what an item is, only that it's cheap or expensive.
** One way to do this is to scatter the base price of each previously tiered item each game on an interval so that it overlaps with the intervals from other previous tiers, perhaps a random number from 1/2 the original price to 2x the original price.
** Or, do away with tiers entirely and simply scatter the base costs permanently. A ring of free action might be 240 or 260 base, because it's on the higher end of usefulness in the former 200 tier. Some fuzzing would probably be needed here to keep things from being unambiguously identified.

Other ideas to reduce the reliance on shops:
* Reduce the potential consequences of use-testing items so it's not as terrible of an idea, such as giving a warning for reading way out of depth spellbooks.
** Make scrolls and spellbooks in particular partially identifiable outside of a shop without having to formally identify them or guess based on frequency (which are currently the ''only'' ways to identify them outside of a shop):
* Higher level spellbooks could be heavier. D&D does this.
* Make spellbook appearances more complex based on level. A simple color indicates a 1-2 level book, an unusual color or appearance indicates a 3-4 level book, a very odd or ridiculous appearance or material indicates a 5-6 level book, and a completely over-the-top appearance indicates a level 7+ book. (Example: "red", "steel", "bone", "jewel-encrusted"). Shuffling of the random appearances would need to be changed so that the books retain an appearance in their original bracket.
* Make scroll label length (or, more complicated, its number of syllables) roughly correlate to its cost. The correlation could be fuzzed a bit, so MAPIRO MAHAMA DIROMAT is probably a 300 zorkmid scroll, but is certainly no less than 200, and NR 9 is probably something really cheap, but might be 100 zorkmid.
* When you read a spellbook, you are given a menu with three options:
** Give the book a cursory glance-over. This can fail with low Int/XL but is fairly unlikely and has very minor failure effects. If successful, it identifies the spell level of the book. Takes 1/10 the usual spell study time.
** Briefly study the book but don't try to learn its spell. This can fail with mediocre Int/XL but will be reliable at high ones. Moderate failure effects. If successful, it identifies the spell contained in the book. Takes 1/3 the regular spell study time.
** Study the book normally with normal failure effects and normal spell study time. Learns the spell if successful.

=== List of existing informal ID mechanics ===
* Weapons: don't usually need to type-ID since there aren't randomized descriptions. Currently there is no way to learn enchantment like there is for armor.
* Armor: most of it doesn't have randomized descriptions, but for those items that do, there is basically only wear-testing and price-ID. Wear-testing is fine assuming the player is able to check for curses, but only on armor types that don't have autocursing gotchas (a rare uncursed helm of opposite alignment or dunce cap).
* Amulets: price-ID doesn't even work; the player has to use-test (safe enough assuming they can verify it isn't cursed or remove its curse, since none of the bad ones autocurse).
* Scrolls: only price-ID
* Potions: monster use identifies most of the beneficial potions (with the notable exception of gain energy), but this is a slow process. Dip-testing identifies the potions of polymorph and sickness, and a few other harmful potions can be dip-tested with a unicorn horn. However, there are still some bad potions (paralysis) that remain unidentified by these processes, so quaff-IDing is only safe if the player has identified the bad ones already.
* Spellbooks: only price-ID
* Rings: sink-ID is pretty unambiguous, but the chance of losing the ring makes it unhelpful unless you have duplicates, which isn't very likely until later in the game.
* Wands: engrave-ID (and fallback on zap-ID) seems sufficient.
* Tools: not many are randomized, but none of the ones that are have debilitating use-IDs, so use-ID seems sufficient.
* Gems: touchstones and unicorns, seems sufficient.

=== Set of possible items ===
Items (perhaps only heavily randomized object classes, so NOT armor) can be inspected somehow, or else come pre-inspected, and your character is able to conclude that the item is one of several possible things from that object class. The number of these possible things can depend on role, and the "fakes" are randomized every game.

Example: a character inspects a potion and confirms that it is either healing, acid, or sleeping. All potions with this appearance will provide the same three possibilities. It's actually acid, but without other identification methods, or ruling out healing and sleeping, it can't be discerned which of the three it is.

Has some problems with the interface; a character shouldn't inspect everything and then have to type-name it. Perhaps this could be automated somehow.

== Spells ==
''Contributions by ais523, FIQ, Chris_ANG, aosdict, jonadab, NeroOneTrueKing, stenno, K2, mtf, Demo, Novel''

=== Charm monster nerfs ===
Most people agree charm monster is too powerful, too low-level, and needs to be nerfed.
* It only works if you're not wearing any armor. (This is apparently how D&D does it.) Alternatively, its chance of successfully charming is reduced the more armor you're wearing.
* Make it more reliable than it is now, but it always fails if you have other pets. (You can then only have one pet at a time without using scrolls of taming.)
* It only tames one monster at a time. (Make it a directional beam with a maximum range of 1.)
* It only pacifies monsters, and can't be used to tame an always-hostile monster.
* Make it do what the temporary pet code in the Bard patch does: the monster remains tame for a fairly short amount of time and then reverts to whatever it was originally.
* Split into three spells: pacify monster (peaceful for charisma*2 turns), charm monster (tame for Charisma*2 turns), and dominate monster (tame permanently or for a long time). 
* It only works on *monsters*, and doesn't work on intelligent beings.

=== Making utility spell failure matter ===
The problem: casting utility spells at high failure rate, such as identify at 95% fail, is a mere inconvenience to players, since they can sit in a closet with a stack of food and wait for their Pw to recharge until they succeed. This is not really a problem with combat spells, since the penalty for failing to cast the spell correctly is a disadvantage in combat, where time matters.
* Large penalties for failing to cast a spell, like a 1% memory loss and 50 hunger.
* Failing to cast a spell locks it for a certain period of time. It would be hard to make this not turn into an even slower grind for utility spells, since the lockout period could just be waited out.
* Make spells never actualy ''failable'', but Pw cost is increased proportional to the failure rate, specifically: <code>real Pw = base Pw / success rate</code>. Under this formula, a 15 Pw spell at 95% fail becomes a 300 Pw spell at 0% fail. This means the Pw cost should be exposed in the spellcasting menu rather than failure rate, even though failure rate still needs to be calculated. Maybe use different colors in the spellcasting menu to denote spells you can cast now, spells you can cast by waiting to recover more Pw, spells you can't cast even at your current maximum Pw, and forgotten spells.

=== Changes to advanced spell forms ===
Advanced spell forms are slightly problematic. Certain spells (fireball and cone of cold) which have advanced versions automatically kick in when the player is Skilled or above, and can't be cast using the lesser form even if the player wants to.
* Some variants give you the choice of casting the basic or advanced form, but this suffers from an interface annoyance (an extra y/n prompt) and the fact that the advanced form is not actually any more difficult to cast.
* Advanced forms are castable even at Basic skill, but have a higher failure rate.
* The advanced form appears in the Z menu once you are Skilled.
* The advanced forms are implemented as higher-level never-generated spellbooks, e.g. "fire storm" and "frost storm". Reading the basic spellbook automatically teaches you the advanced spell as well.
** This allows you to balance them separately; in the case of fireball and cone of cold, the lesser spells could be dropped to level 3 or so and the advanced forms elevated to level 6.
* The advanced forms are broken out into completely separate spellbooks that must be discovered and learned separately.
** This makes the balance of spellbooks a concern, since it would add more books of a certain school.
** Both of the ideas that involve higher level spellbooks may create a problem with the Z menu only allowing 52 different spells if more advanced forms come along, not that that can't be worked around.
* Skilled+ casting does nothing to the actual spell effects, but allows you to cast the spell mentally.

=== One-time-use spellbooks ===
Instead of books having spestudied charges which leads to a lot of issues with polypiling, you read them once and they disappear, but you get 3 times the spell memory.
* This is intended to remove spellbook micromanagement.
* Spellbooks would need to be considerably more common than they are in vanilla. In FIQhack, where this was originally discussed, spellcasters generate with books, and the level of dropped spellbooks scales well as the game progresses since more dangerous monsters carry higher-level books.
* This addresses polypiling by allowing the player to polypile the book as much as they want, but they can only read it once.
* Slight nerf for people who finish their games in under 60,000 turns, since they can't use a spell for free confusion.
* Also a problem for people who play very long games, because they will need to find or write replacement spellbooks; however, this was sort of already the case.
* May make polypiling unknown spellbooks too popular, since an unknown spellbook is likely not to be the one you want, or you have price-IDed it and know it's something you will never use, and you can now poly without consequence. Perhaps address this by giving polymorphed spellbooks an elevated chance to become blank, and blank spellbooks do not poly into anything else.

=== Wielding spellbooks ===
The wield slot is fairly underused among object classes, and there are a number of interesting bonuses we can add to spells if the corresponding spellbook is wielded.
* Decreases failure rate of the wielded spell (utility spells might need to be made higher-level/harder to cast to maintain balance).
* Or decreases Pw cost of the wielded spell.
* Allows you to cast the wielded spell even if completely forgotten.
* Allows you to cast the spell without knowing it already - the Z menu gets an additional "-" option to cast from the spellbook in hand if you don't know what that book is.
** Casting from an unknown spellbook will immediately check for reading success as if you had read the book: if you succeed, it then moves on to other checks like whether you have enough power, etc and you may cast the spell. If you fail, you get a random failure effect appropriate to that spellbook.

=== Ritual spells ===
More powerful and more expensive spells which have some esoteric effects you can't get otherwise. The main differences between ritual and normal spellcasting are that they consume valuable, hopefully non-renewable components, take a number of turns to cast instead of taking effect instantly, and may require you to be in or set up certain circumstances.

Various ritual spells that have been proposed:
* Ball spells which consume a gem as focus and create a ball of elemental power that hits surrounding squares but not you. (Long casting times would probably make rituals infeasible for combat though.)
* Temporarily increase your carry cap by a great amount. (Other new intrinsics as required.)
* Resurrect a corpse as a tame monster (necromancy).
* Grant temporary intrinsic life saving.
* Single controlled polymorph with a greatly increased duration.
* Summon a demon, demon lord, or demon prince. Requires 5 cursed candles and a marker (to draw the classic pentagram). If summoning a named demon lord, it's either random or there's some expensive way to control who shows up. The demon lord could be peaceful, but with current behavior this is useless. Possibly summoning them allows you to make a pact with them.
* Remove the graveyard status from a level (would need to be expensive, and perhaps involve the Book of the Dead, and multiple different headstones).
* Grow a tree. This consumes at least a piece of fruit. For anti-farming the tree should probably not produce fruit or bees when kicked.
* Create a portal between two levels of your choice (doesn't work with the Amulet obviously, but otherwise works)
* Create an artifact (that is, you somehow imbue an item with properties it can't normally get).
* Bless items. Consumes a blessed scroll of remove curse.
* Genocide a genocidable monster. Consumes a figurine of that monster plus other costly things.
* Reverse genocide a monster. The monster may or may not have to be normally reverse-genocidable. Consumes a figurine of that monster plus other moderately expensive things.
* Charge something. Requires a rare ingredient - perhaps a dilithium crystal.
* Summon tame elemental(s). Among other things, ingredients include: a potion of water, any beatitude (water); a rock (earth); lit candles, a lit oil lamp, or a lit potion of oil (fire); an amulet of magical breathing (air).
* Create a magic lamp. Needs an oil lamp (of course) and a figurine or mask of a djinni (or possibly a nearby live djinni).
* Make the current level non-teleport. Requires a scroll of teleportation and that the caster be standing on an anti-magic field at (?) either the start or the end of the ritual.
* Create a fountain. Requires a statue of a medium-sized or larger monster, which gets destroyed (by turning it into the centerpiece of the fountain). There may be potential for wishing abuse; perhaps the fountain should be flagged so that it can't produce a wish-granting water demon.
* Turn a regular knife into an athame. Components include other bladed weapons with positive enchantments adding up to 20 or something; all of these charges will be drained to +0 in the creation of the athame. The resulting athame is +0, regardless of the charges on the component weapons or original knife.
* Create a tame golem or golems. Requires a large amount of total weight of objects made out of the golem's material.

Ritual spells come in spellbooks like usual, but aren't stored in your spell list. Instead, reading the spellbook prompts you if you want to begin its ritual and tells you the necessary ingredients and circumstances you need to satisfy as preconditions. If you meet all the conditions and answer yes, you initiate the ritual. (For simplicity, this should probably burn up / expend all the components instantly.) You cannot begin a ritual while in the process of casting another ritual; this should probably be implemented as a precondition.

Apart from the component cost, rituals act as a constant drain on your Pw until the ritual is complete. If something distracts you in the middle of the ritual, you can go take care of it and then resume the ritual as long as you have the Pw left to finish it. (You could also drink gain energy during the ritual.) The only way for a ritual to fail, possibly backfiring with bad effects, is for you to run out of Pw while it is incomplete. 

In addition to its preconditions, each ritual also has some postconditions: common to all rituals is that you have been casting the ritual for at least some length of time, but there may be others, such as standing on the square where you began the ritual, or have another item, or kill a monster, or something. There may also be other conditions such as "moving off the space where the ritual started breaks and halts the ritual".

Every time you stop casting a ritual (whether it succeeded or failed), it increments the spellbook's spestudied field; the book will eventually disintegrate after casting it a certain number of times.

=== Miscellaneous ===
* Bump the spell of sleep up to level 3 or 4.
* Wielding a quarterstaff confers the same benefit as wearing a robe but does not stack with it (implemented in FIQHack).
* Wielding a wand of nothing confers the same benefit as wearing a robe but does not stack with it.
* Wielding an identified wand which matches a spell (wand of light -> spell of light, wand of death -> finger of death, etc) drastically reduces your failure rate when casting it. Perhaps casting the spell while wielding the matching unidentified wand should identify the wand.
* Add a spell of collect arrows: it magically retrieves all objects on the current level that you've thrown or fired at some point in the past. (Possibly limited to weapon class objects).

== Object materials ==
''Contributions by AmyBSOD, aosdict, Chris_ANG, jonadab, bug_sniper, ais523''

=== Properties of weapons ===
* Iron - good against fairy, elf, and fae creatures
* Gold - associated with the sun, so good against undead. Blunt gold weapons get a d2 damage bonus due to being heavier.
* Platinum? Copper? Metal? Wood?

=== Effects of gear ===
* Mithril body armor prevents bisection.

=== Elves and iron ===
* Elves take extra damage when hit by iron. Not as much as silver, but still appreciable.
* Elven players take a small amount of damage when putting on or wielding iron gear, but get no further penalty. (dnethack hurts their regeneration rate while wearing iron, which is another option).
* Possibly some detrimental effect when wielding iron weapons as well, a to-hit or damage penalty, or negating bonuses from dexterity, strength, and skill, or something.
* This is balanced by elven racial equipment being better (not improved; it's already better).

=== Metalworking ===
Would be a pretty neat addition as a service that offers things the player can't do on their own (probably not a shopkeeper service though), and some things they could do on their own but lack the resources. In particular, silvering has a lot of potential if the [[object materials]] patch is used. Also see [[#Crafting]] on this page.

== Point buy for starting characters ==
''Contributions by ais523, jonadab, aosdict, Tarmunora, FIQ''

Point buy is an idea originally from ais523 that is intended to address startscumming by unrandomizing starting stats and inventory and letting the user spend points on stats and equipment however they like. dtsund's [[User:Jonadab/ClassOverhaul|class overhaul proposal]] also addresses unrandomization of starting inventory by simply removing all the random chances to get items, but doesn't involve point buy.

=== Starting stats ===
* Any point buy for stats is likely to involve a tedious interface. Developers could get around this by making it options-only, perhaps in a way that allows the user to say "buy to get my Strength up to 10, and my Int up to 9, and randomly pick the rest", but specifying it per-role could get annoying.
* It's important to allow people who want to start and splat games rapid-fire to do so, and it would be preferable if new players didn't have to learn the complexities of a new interface.
* The rc file must allow the user to specify starting stats per-role in this case, or specify that they want random stats.
* "Dump stats" like Cha, and Int and Wis for non-spellcasters, allow people to buff their important stats at the expense of unimportant stats, which may indicate some underlying balance issues with these stats or that the stats can have too wide of a starting range.

=== Starting inventory ===
* Even in a non-point-buy system, for starting inventory in cases like for Monk and Wizard where the player gets a random spellbook with equal weight among the possible choices, the player should be able to select which.
* Any point buy system for inventory should probably be options-only, since designing an interface to do so would be complicated.
* Naturally, items like magic markers and rings of polymorph control cost lots of points, whereas things like apples and oil lamps cost only a few.
* Some items should probably have maximums.
* This would come at the expense of players who actually want different nonrandom starting inventories and don't want to have to edit their rc file every time.
* If the player's options leave some or all of the available points free, the game will randomly buy items until there are no points left.
* Unspent points should probably convert into a certain amount of gold.
* Possibly the default items are expressed as a list which consumes most or all of the points and is sorted from highest priority to lowest, and ones the user specifies get moved to the beginning of the list, which will push the low-priority items into the range of not being able to be purchased.
* Certain items, like the knight's lance and probably most armor, should not be purchasable, and the character always gets them.
* FIQ proposed a system in which you can specify one item, and the game will try to reroll your starting inventory many times until it gets that item. Since this is effectively built-in tool-assisted startscumming, it gets tracked as a conduct.

== New roles ==
''Contributions by Demo, aosdict, Grasshopper, Tarmunora, jonadab, ais523, FIQ, Chris_ANG, NeroOneTrueKing, Luxidream, K2, greqrg''

=== Alchemist ===
Would require overhauls of several systems, but it's at least fun to discuss what the mechanics of such a role would be, and it's now being more seriously considered for dNetHack (for up-to-date discussion, see https://etherpad.net/p/dNethack_Alchemy).
* The main form of combat is to create phials of potion (where 1 potion splits into many phials), which can be tossed at enemies to cause potion effects on them. The main potions used are things like acid, paralysis, (lit) oil, and confusion.
** Phials come in all the same types as normal potions but have somewhat weaker effects.
** You can dip a stack of empty phials into a potion to fill them with that potion (up to some maximum).
** Thrown phials have the same exact splash damage effect on things as throwing the potion would produce, but drinking it is a small enough dose to only cause the splash damage effects to the drinker. Requires some balance so that splash damage is useful against monsters but not useful for the player to drink for beneficial phials.
** Phials can be dipped into potions, but nothing can be dipped into phials.
* The quest artifact is the Philosopher's Stone.
** The quest leader is Nicolas Flamel and the nemesis is an Avatar of Death (like Death, but weaker).
** More fun possibilities here if you have the object materials patch.
** Its base item type could be a ruby (but perhaps not because dnethack makes the Heart of Ahriman a ruby) or a garnet, based on its color in Harry Potter, or an opal.
* Can also create alchemic gizmos: smoke bombs from potions of blindness, firebombs from potions of oil, all lighter and more numerous and useful than the base potions.
* Start with all potions identified.
* Could start with an alchemy kit, which is a rare tool find for other roles. NeroOneTrueKing proposed a set of mechanics for an alchemy kit:
** Has 3 compartments. The first accepts only potions/phials of polymorph (or perhaps it just has charges and you can recharge it by using potions of polymorph).
** The other compartments must each only contain items of the same material.
** A success chance is displayed based on the amount of polymorph potion available, the weight ratio of the two compartments, and the materials themselves (metal can transform into metal relatively easily).
** A successful use swaps all of the materials of the two compartments.
* Needs mechanics such that in an Alchemist's hands, no potion is useless.


The invoke effect of the Philosopher's Stone is heavily debated.
* It creates potions of the Elixir of Life. This potion cures disease and restores lost attributes, but most importantly it grants temporary intrinsic lifesaving. If you die with intrinsic lifesaving, you lose the remaining time for the intrinsic.
* Creating potions is way too powerful since the player will be able to bank them, so nerf this: perhaps you can only get Elixir of Life by dipping the Stone into a potion of full healing, or something. Or Elixir goes bad after a while and reverts to water, making it usable for before a fight but not for stashing.
* The Elixir should not be _more_ powerful than a potion of full healing, or the invoke effect of the Staff of Aesculapius - healers should be the best at actual healing. Probably, getting lifesaved from intrinsic lifesaving will only restore enough HP to stay alive a little longer.
* The Elixir gives a large temporary boost to HP regeneration.
* No Elixir of Life; it instead turns potions of sickness into (extra? full?) healing.
* The Stone can turn metal objects into gold or can turn rocks into gold pieces when rubbed on them.
* When dipped into gain level or gain energy, transforms the potion into polymorph.

A really great Alchemist implementation would probably involve a full alchemy overhaul which adds herbs and fungi, harvesting ingredients from corpses, cooking, and interesting ways to combine everything. The challenge with making this is how to make it useful for other roles and not just the alchemist.

=== Artificer ===
* Artificers can innately see charges on things and use wands at a higher skill level than everyone else.
* Starts with an inventory of consumables comparable to vanilla wizards', a scroll of charging, offensive wands, a magic marker, and random tools.
* Starts with all armors (magic and nonmagic) identified and all tools identified.
* Restricted in nearly all weapon skills like a monk, or can only reach Basic in a few ones like knife.
* Quest involves lots of golems.
* Quest artifact grants double damage with tools and gives blessed charging when invoked.
* Gnome is a playable race.
Also see [[User:Jonadab/ClassOverhaul#Item User: Tinker]].

=== Druid ===
Intended to be a more balanced form of SLASH'EM's doppelganger race, druids are highly attuned to nature and possess innate shapeshifting abilities.
* You begin the game with polymorph control and get polymorphitis at XL 5 or so.
* Possibly you start with a wand of polymorph, or potions of it.
* Inventory could be severely restricted, so you have to figure out how to do most things through polymorph.
* You have the power to change into a tree, which will make most monsters ignore you. While in tree form, you are immobile but regenerate HP and Pw faster. Orcs might attack you with axes, a la Tolkien.
* Without extrinsic polymorph control, your polymorph control limits you to changing into forms with the M1_ANIMAL flag.
* Possibly have limited access to #polyself outside of wizard mode, so they can change intentionally and not randomly. Would work best as an ability with a timeout, or cost Pw outside of wizard mode.
* Possibly, the monsters you can polymorph into must have a certain base level that's tied to your XL somehow (maybe XL/2). If their base level is too high, you can't polymorph into them.
* Your controlled polymorphs always succeed - you will never accidentally fail and "feel like a new woman" with the 20% chance that all other roles have.
* You are seriously bad at combat in your regular form, having very little weapon skill (nothing can be advanced to Expert, possibly not even to Skilled), and physically weak in your normal form. Combat in a polyform should be incentivized enough so that it isn't really worth it to wear any armor. Maybe you should get to-hit and damage bonuses while in a wild form?
* [This may be more of a polymorph control YANI in general]: Diminishing returns on polymorph time limit that prevent you from reusing the same form(s) over and over and over again.
* The critical balance needed is to make polyselfing powerful and awesome to play with and use for typical combat, but simultaneously polyselfing needs enough restrictions that it doesn't just turn into Master Mind Flayer: The Game.
** One proposed restriction: you can only turn into monsters you have already encountered, or if that is too lax, into peaceful or tame monsters adjacent to you at the time. The druid should be able to pacify most animalistic monsters to take advantage of this (temporarily?)
* The starting pet is a woodchuck (or wolf). Pantheon is probably drawn from Celtic mythology, though hopefully not overlapping with Knights.
* Some heavy polymorph / monster / player as monster tweaking is probably required, in the sense that there should, ideally, be valid reasons to exist in any given polymorphable form.

== Alchemy ==
''Contributions by FIQ, ais523, jonadab, aosdict, Chris_ANG''

NetHack's alchemy system is balanced around the assumption that the player will not hold onto nearly every potion in the game, turn them to water, and polypile them into alchemy ingredients; however, this is not hard to do. Should the player do this, they can amass hundreds of hit points worth of full healing potions, or all the gain ability potions required to max out every stat, or get dozens of potions of holy water.

For most potions in the game, diluting for holy water or alchemizing/polypiling for alchemizing is their ultimate fate, and there are enough potions so that the player never really has to agonize over what to do with a potion. One solution to this would be to make more potions than just acid effective for throwing at monsters.

The [[color alchemy]] and [[gem alchemy]] patches are unsatisfactory, as is any system that ties alchemy recipes to the random appearance of potions. This is because it makes the game choose at the beginning whether powerful potions can be produced out of junk potions/gems, or out of expensive potions/gems, or not at all; all before the player gets a chance to learn how alchemy will work in this game. It has a large impact on overall strategy that the player can't discover until probably the midgame. At the same time, having hardcoded alchemy rules is unsatisfactory because it's inflexible and carries a heavy spoiler requirement.

Random alchemy is also odd: dipping the same potions in the same way can yield different potion results.

=== 1 + 1 = 2 ===
A radically different system from how alchemy currently works: no matter how many potions are involved in the dipping, only two are consumed, and two alchemized potions produced.
* Intended as a balance fix for the player's current ability to make stacks and stacks of full healing, gain ability, or gain level potions, and promote use of found potions instead of diluting them.
* Significantly, potions of holy water mostly work like they do now - the holy water does not mix with anything and is consumed, while the dipped item becomes blessed - but you can only dip a singular item into the holy water, including other potions. This loss of the ability to mass-produce holy water creates a significant balance change.
** Or it could sometimes make two holy waters, but be biased against it, and allow both waters to become uncursed in the process.
** Still unbalanced, since holy water can otherwise be mass produced through water prayers and blessed confused remove curse.
* Undiluted potions can be duplicated by dipping them in normal water, e.g. one potion of gain level + one water = 2 diluted potions of gain level.
** Diluted potions may need to have weaker effects to compensate for this, or undiluted potions stronger effects.
** Or potions in general should become rarer, and possibly generate diluted.

=== Sink alchemy ===
Allow sinks to be catalysts for alchemizing things. (Or possibly add a "cauldron" as a new piece of dungeon furniture, but that's iffier.)
* You can dip potions into sinks to pour them down the drain, experiencing the vapor effects in a safe way. (Pouring polymorph down the sink of course polymorphs the sink.)
* If you don't pour the potion down the drain, you instead mix it with the fluid from the tap, which is usually water but can already be a random potion.
* Possibly, doing alchemy in/on a sink is more efficient. There are many possible forms this could take, such as:
** Potions not diluting when you mix them.
** Reduced or zero chance of an alchemic blast.
** You can get results from mixing potions that you can't otherwise (flavor for this is weak, are you... heating them somehow with the hot water?)

=== New alchemical objects ===
* Flask, holds multiple quaffs of a single potion type (so that holy water can't be mass-created but other potions can)
* Mortar and pestle, can grind gems / other things into dust which can be used to make potions
* Alembic, can distill potions from things in the dungeon such as corpses.
* Recipe books/scrolls, which tell the reader how to create a certain potion through alchemy, and identifies the result potion or even all potions involved.

=== Alchemy skill ===
Non-weapon skill that has various effects on alchemy: make alchemical blasts less common (or zero at high skill), and increase the probability that mixing certain potions yields the right result.

== Cantrips ==
''Contributions by K2, aosdict, jonadab, ais523''

Cantrips are level 0 spells that cost d2 or d3 power to cast. In order not to let them be unbalancing, they don't train skill and are mostly useless, except in certain circumstances or for low-Pw spellcasters who can't do much of the bigger stuff yet. ais523 suggests that good candidates for cantrips might be things that have little combat use, and whose effects could be duplicated by backtracking or other tedious things, but would be useful to avoid boredom. Given their cheapness, they should probably not train skills, and may not even need spell schools. Most ideas for cantrips seem to be a little too powerful and would do better off as normal spells (and are added to this page as YANIs for separate spells); however, those that seem like they would fit are listed here.
* Increase the odds of monsters dropping a corpse in the next few turns.
* Create an empty unlocked chest. (This would need some restriction so you can't farm and sell them.)
* Mark a map square with a symbol, perhaps a comma, that is no different from normal floor but shows up on #overview and the normal map view.
* Deal some small damage, such as d5 or d6, to a nearby creature. (Acid Bubble from D&D is a nice corresponding cantrip.)
* Dig out a single square.
* Create a cancelled hostile yellow light. It cannot explode at you since it is cancelled, so it becomes an autonomous light source of radius 1, which can't follow you down levels like a pet can. Killing it should not grant you any experience; otherwise this would be easily farmable.
* Light a radius 2 or 3 area permanently, like a weak form of the spell of light.
* Mage hand: you indicate a direction and the nearest item on the floor in that direction, assuming it's under 100 weight or so, is brought to you and is placed in your inventory. This can be used > to get things out of pits.
* Create an illusion of yourself at your spot. The illusion never moves. Monsters that see it assume it is you and will attack whichever one is nearer (the illusion is instantly destroyed if attacked).

== Monster AI changes ==
''Contributions by jonadab, FIQ, aosdict, flump, mtf, Chris_ANG, xyzyxx, Pavel''

Monster intelligence and AI strategies should be much more fleshed out than the current definition of "having hands and neither mindless nor animal". A clear way to do this is to implement different degrees of intelligence or even just an Int stat for monsters, which affects their strategy for doing certain actions like fleeing (do they flee intelligently like monkeys do, or in a random direction?) and using items (a dumb monster might try to read a scroll of fire and burn itself to death).

=== Smart monster attack strategy ===
Very intelligent monsters calculate whether it is more advantageous in terms of damaging the enemy versus taking damage themselves to pursue a target in melee, keep a safe distance and attack from range, or flee. Complex solutions would involve the monster storing lots of data about which attacks it has seen its opponents perform; however, this might get memory-intensive and expand save files quite a bit. A possible algorithm that relies only on game state and is based on FIQhack's dragon AI algorithm is as follows:
 If able to attack at range (spit/breathe/shoot missiles/use items/etc):
   If the target is in range but not adjacent:
     Attack at range.
   Else if the target is adjacent, and is at least as fast as the monster:
     Attack in melee, or use ranged attacks point blank.
   Otherwise:
     Try to move somewhere aligned with the target, as far away as possible while still being in range.
 Else if the monster is unable to attack at range but will be able to soon (dragon):
   Stay out of line with the target.
 Otherwise:
    Close to melee range.

=== Group AI ===
Monsters that spawn in groups are currently completely individualistic and try nothing more complex than charging towards the player and hitting in melee once they get there. This makes it easy for the player to cheese what would otherwise be tough battles, e.g. by standing in a doorway and killing them one by one, or by kiting them. There are some proposals for smarter AI:
* If a single monster in a group is next to the player, try to pull back until allies can get next to the player.
* Avoid doorways and narrow corridors; if you are in an open space, stay there unless you decide to move to another open space, and hang back from the doorway where the hero is, forcing them to enter the room in order to pass.
* Groups of intelligent monsters also try to stay out of the way of ranged fire if possible.
* If the current strategy is to defend a certain area, form ranks to block the player from reaching it.
* Pincer maneuvers; some monsters of a group will split up and try to get behind the hero or attack from another side. If the pincering group hasn't gotten in position yet, the other group will fall back until they catch up.
* Group "leaders" (loosely defined as a M2_LORD or M2_PRINCE monster in a group of monsters of the same monster class) will try to put the group between them and the player. The presence of a leader could also buff the strategy or intelligence of the group it is in.
* Wolf pack: the monster of the class with the highest level, or failing that the highest max HP, "leads" the pack, and all other members key in on this leader and follow it. This means if you get the leader to flee, the rest of the pack will flee as well.
* The Yendorian Army can form a phalanx, which is an ordered rectangle of soldiers. Will stick to wide open areas, try to stay out of the range of ranged attacks until they can swarm around you. Enemies forming a phalanx could receive to-hit and AC boosts.

=== Golem AI ===
Golem AI/strategy could be selected from a set of possible directives when the monster is created. They follow this directive completely and literally, which may result in some interesting behaviors. The player can #chat to the golem to have it mumble its directive.
* ''Kill all humans'' - golem attacks the nearest human it can find, not necessarily the player.
* ''Gather gold'' - golem pathfinds to the nearest gold on the level. If that happens to be carried by a monster, attack it.
* ''Build a castle'' - golem seeks out boulders and tries to pick them up and pile them into one small collection of spaces on the level. If you destroy or move them, it becomes hostile.
* ''Get corpses'' - golem tries to collect corpses, but will not hesitate to make more if there aren't any more on the level.
* ''Build more of myself'' - golem tries to collect the material it's made of. It attaches these to its body, increasing its HP and maximum HP; when its maxHP is high enough, it splits into two golems like a blue jelly.
This would probably require a general AI overhaul.

=== Miscellaneous strategies ===
* Default: Monster roams aimlessly unless they can see hostiles, in which case they beeline towards those hostiles. Smarter monsters might remember the last place they saw a hostile and beeline towards that square when the hostile goes out of sight.
* Lure: Active only when a monster is fleeing and knows about a trap in the vicinity. It tries to get the trap between itself and you.
* Blocking: Monster tries to get between the player and a certain space. Won't work well when there's only one of it, but will do nicely in small or large groups.
* Zombie resurrection: If zombies can resurrect each other through physical contact, living zombies will try to move towards zombie corpses they can see.
* Throw weapon versus wielding it: Mostly useful for things like daggers or knives. Most monsters should be smart enough not to throw away their last melee weapon when they know they can hit for more damage with it. They will, however, unwield weapons and hit you with fists if their only weapon left is grossly unfit for melee (i.e. crossbow).
* Darkness: Try not to move out of darkness / into darkness unless there's no other choice. If in the wrong one and doing nothing special, beeline towards the nearest visible way out of it. Most useful for gremlins who want to stay in darkness.
* Passwall: if monsters cannot take physical items with them when they phase through walls, they will not actually pass through walls while carrying any items they care about, unless they are fleeing, in which case they will abandon the items.
* Food smells: If the hero is carrying a lot of food in open inventory, monster AI may be more effective at tracking the player, depending on if the food is anything the monsters like to eat. Carrying around lots of fleshy food like tripe rations or meatballs helps carnivorous monsters track, carrying around produce helps herbivorous monsters track, tins don't have any scent or effect, inediate pets get no tracking bonus.
* Hero displacement: Monsters often attack each other because they think the hero is displaced where another monster is. The smarter a monster is, the more chances it should have to re-roll this displacement roll as long as it keeps landing on other monsters. Or else, if there's only one displaced image, smart monsters should conclude it's not where the other monster is and lash out randomly at empty space.
* Bones ghost AI: camp on the bones pile, guarding it, never chase the hero away from it.
* Insects returning to the hive: bees periodically path back to their hive unless they're actively chasing or combatting something. Ants do this too, and even pick up and bring back food items.
* Swarming AI (bees and possibly other insects): before moving, they calculate if they can see any others of the same monster, and if so, they are disincentivized for moving into a space where they would lose sight of all such monsters. This should keep swarms actually cohesive but still able to move along corridors and pursue the player.
* No reason to move: the monster doesn't move, or moves infrequently and randomly, unless it sees you as an enemy. It can have a normal speed and doesn't need to be sleeping or peaceful or anything. If it no longer detects you, it may return to its state of not pursuing you.

== Resistances ==
''Contributions by FIQ, aosdict, ais523, jonadab, NeroOneTrueKing''

The current resistance system is unsatisfying, because most resistances separate the effects of something into a binary outcome: worse effects with no resistance, ameliorated effects with it. Most resistances also are eat-once-and-be-protected-forever, which is uninteresting in the long term. Proposed solutions to this generally assume that there will be some distinction between resistance and immunity, which offers better (or total) protection but is not normally obtainable as a permanent intrinsic effect. This also enables partial resistances (as found in SporkHack) to be used, though some ideas still treat them as binary - either you have it or you don't. [[FIQHack]] recently implemented a form of this.
* Possibly extrinsic immunity isn't as good as inherent immunity.
* Resistance halves HP damage and cuts attribute loss down to 1 point.
* Role benefits should probably only be resistance and not immunity.
* For partial resistance, damage is easy enough to do (express your resistance as a percentage and cut damage by that percentage), but many effects, particularly those protected by MR, are binary, and will be tricky to adapt.
* Resistances could start at 100% when you get them, but decrease by 1% every time it protects you from something.

== Thief stones ==
''Contributions by ais523, aosdict, jonadab''

Add a new gray stone, the "thief stone":
* It is a magical gray stone that one-way teleports items out of your inventory into a particular square on the level it was generated in.
* This works across levels; carrying a thief stone to another level and using it will teleport items to the same square on the original level.
* If you pick up the stone while it is unidentified, it will teleport both it and some item back to its spot, and become identified.
* The chosen location will be somewhere suitable for stashing: a vault, closet, or any space with a container on it is good.
* Barring this, pick any square that is walkable and not specifically ''unsuitable'': the insides of shops, doorways, etc.
* An empty chest will be generated on the chosen location if there is not a container already there.
* When formally identified, a stone will say "(keyed to branch:dlvl)" where that is the branch and level that it sends items to.
* The player can rub it on items or apply it on items to teleport them to the keyed location.
* Items that teleport from the stone will go into the topmost container on the keyed location. (The player can put an ice box on there instead if they really want to...)
* The stone cannot teleport mundane items, in order not to encourage massive stashing of every item in the game. It will normally only work on treasure and magical items (oc_magic).
* Hitting a gold golem with the stone will levelport the golem (and possibly also the stone) to the keyed level. This works on the player too, if polyselfed into a gold golem but not carrying the Amulet.
* The stone can be cancelled and become "inactive", which will make it not teleport anything anymore. Possibly, blessed charging re-initializes it.
* Beatitude determines what the stone will teleport:
** Blessed stones work on all magical items, artifacts, gold and gems (including glass).
** Blessed stones also intervene automatically when you would lose gold from a spellbook, leprechaun, throne, fountain, or whatever. The gold will be sent to the stash instead of being removed.
** Uncursed works on all magical items but ''not'' artifacts, gold or gems.
** Cursed works on all the same things uncursed does, but will not work when the player tries to use it intentionally.
** Additionally, cursed stones have a 10% chance of activating whenever the player tries to pick something up, sending the item to the keyed location instead.
** Attempting to pick up a cursed stone will always teleport it back to the keyed location, regardless of whether it is identified. Unless the player is standing on they keyed location, in which case they may pick it up normally.

== Crafting ==
''Contributions by aosdict, ais523, jonadab, mtf, ChrisE''

=== Craftsmen's Guild ===
* Populated with master craftsmen who work on the principle of "valuable junk items + very large sums of gold = desirable items". They can also do some things available to the player, like increasing weapon enchantment, without needing the specific consumables needed for the player to do it.
* Would serve as a replacement or stand-in for the black market. Resolves some of the problems with balancing black market shopkeepers: if you kill the black market staff, you can have every item in the market, so black market staff must be insanely powerful. If you kill a master craftsman, however, you don't get anything of value. Therefore, master craftsmen don't have to be insanely powerful, or even good fighters.
* Not as good as wishes; there are some things they cannot make for you, like magic lamps, and many magical tools. You cannot specify enchantment or blessing either. For items for which enchantment doesn't matter, the material cost will be higher.
* The interface works by #chatting to them. They will ask you what you want to create, and you enter it (using the wish parser logic to extract the proper object class), and then they will tell you the items and gold they will need for it. These could either be randomized or use certain fixed ingredients with some randomization or use completely fixed recipes; if randomized it will be deterministic for that item for that craftsman in that game. You are then prompted to select the items from your inventory.
* For gold and other balance reasons, this would probably work better the farther it is into the game; maybe it could even be found deep into Gehennom. Maybe you even have to liberate it from a demon lord.
* Craftsmen might include:
** Metalworkers (see below)
** Wandmakers (produce wands)
** Scribes (produce scrolls and spellbooks)
** Alchemists (produce potions)
** Toolsmiths (produce mundane and some magical tools)
** Jewelers (produce rings and amulets)
** Sculptor (produce statues and figurines)
** Leatherworkers (produce leather items and saddles)
** Chefs (produce food)
** Arcanologists (transfer charges/enchantments from one item into another, consumes only gold and not items)

=== Metalworking ===
Probably the most important sort of craftsman for many characters. There could be multiple types, each specializing in one type of metal, or just one type that does everything.
* Silvering items (or gilding, or copper-coating) should require you to use up junk silver items equal to some amount of weight proportional to the weight of the new item. The zorkmid cost of silvering should be very high.
* A forge room type (probably containing lava and maybe some junk items like iron chains) could be added which has one or more smiths in it (silversmiths, goldsmiths, blacksmiths).
** Goldsmiths seem rather pointless right now, since there is only one gold item (the ring). They would be more useful if gold equipment existed and conferred some benefit.
** Blacksmiths don't have much to do as far as turning items into iron goes, but they could produce iron weapons of a type the player wants, or repair and improve iron weapons and armor (increasing its enchantment).

=== Player crafting ===
ais523 has pointed out that if there's a craftsmen's guild or even scattered craftsmen, the process of traveling back and forth to and from it might become busywork. So if players could craft things on their own, that might be better.
* Would probably need properly flavored terrain for workstations, like a furnace or smelter, for certain crafts, otherwise flavor is too weird.
* Fixed, non-simple recipes (e.g. existing scroll crafting is a simple recipe) are a heavy spoiler tax and should be avoided.
* This could be simple for certain types of items, as in requiring some silver or gold and a diamond to craft a diamond ring, but doesn't explain where any magical effects come from, and also might weirdly tie crafting recipes to randomized appearances which have previously been meaningless.
* Probably requires a few more "base" crafting materials, some source of leather, some source of wood, etc.
** Corpses could decay into bones, which disappear themselves with a longer timeout, but in the meantime can be used to craft bone stuff

== Trap scaling ==
''Contributions by aosdict, mtf, jonadab, FIQ, ais523, Chris, rumflump, firemonkey''

Traps don't scale very much (floor traps' having minimum dungeon levels for random generation is about it), and this hurts their balance. Since a trap will have the same flat effect in all situations, it tends to become unthreatening to a player sooner or later, and then having it appear in the rest of the game is pointless. Conversely, some trap effects are too deadly to early characters. In Gehennom, the traps have probably literally been designed by demons, yet the only difference between Gehennom and the rest of the dungeon is the existence of fire traps.

=== Floor traps ===
* Magic traps' blinding and summoning monsters effects should be split up, since both at once tends to make them much more fatal, especially to early players.
* Perhaps magic traps' summoned monsters should be generated with a reduced [[monster difficulty]].
* Statue traps' summoned monsters should be generated with an increased difficulty. +5 was proposed for this, but this may be too high.
* Falling rock traps can dump multiple rocks onto you at once, up to (depth/4). Damage is taken for each rock. If a trap would drop 4 or more rocks on you, it may instead drop (rocks/4) boulders on your head instead. Helms should be less effective at reducing damage from falling rocks, and almost useless at reducing damage from falling houlders.
* Pits get deeper, which makes them deal more damage, might cause [[wounded legs]] with a chance that increases with depth, and take longer to escape from (or are so deep you can't climb out at all).
* Rust traps might target your pack instead of your armor or gear. Probably should be renamed to "water trap". On deeper levels, when the game would generate a rust trap, it has an increasing chance of replacing it with an acid trap. These deal corrosion and acid damage (and quite a bit of it, like having multiple potions of acid dumped on your head).
* Traps could trigger based on your weight. This makes the trap more likely to trigger on a heavily armored character or one who has collected a lot of loot. Would work nicely in the Gnomish Mines, since gnomes are light and don't tend to carry much stuff. Certain traps could also trigger to a lesser degree if you weigh enough to trigger it but not a whole ton.
* Anti-magic fields in Gehennom can attempt to cancel you or your gear. (Would work better in something like FIQHack where there's a cancelled status effect).

=== Container traps ===
Container traps' effects also scale based on dungeon level (ideally on the level a container generated, not on the current level, so a player can't levelport a chest up to level 1 and cheese the trap.)

In addition to adding some more effects, also add some effects which cosmetically are the same as other ones, but are more or less damaging. This would, however, make untrapping containers even more useless than it is now; perhaps a trap should stay armed even after you set it off. Another idea is to give certain traps an arming item, like a potion of oil for the fire effect and a land mine for the explosion effect. Successfully untrapping it will deposit the arming item into the container.

Also, make container traps independent of Luck, because currently they encourage the player to ignore containers until Luck is maximized.

Unsorted new trap ideas:
* A hand wielding a cream pie comes out and pies you in the face. Untrapping this will drop the cream pie into the container's inventory.

=== Door traps ===
Instead of making all trapped doors explode and stun the player, add more varied door traps. The trap should be determined based on depth. It should also be selected deterministically based on the coordinates of the door (a convenience so that a trapped door will always have the same trap effect without having to store which trap it is.)

Additionally, new traps can also be used with more door states, rather than have all traps trigger by trying to open the door. Nondestructive traps could also remain on the door until the door is untrapped, rather than vanishing.

An interesting addition would be if doors were made restrictedly or completely untrappable, in order to prevent optimal strategy from being attempting to #untrap every door that the player comes across. Or possibly an attempt to open or close a door should do a cursory trap check.

== Terrain ==
''Contributions by aosdict, AmyBSOD, bug_sniper, jonadab, NeroOneTrueKing, statuesurfer, FIQ, stenno, Chris_ANG''

'''Fire terrain'''

Fire terrain is a square that is on fire. It displays as an {{orange|.}}. (Depending on how nasty this will be to non-color players, the glyph should perhaps be changed.)
* Fire terrain has a certain amount of burning wood material on it.
* Standing next to or on fire terrain grants cold resistance, but standing on top of fire terrain has the same effect as a fire trap whenever you end your turn on it.
* The fire eventually burns out and reverts to normal floor, the duration determined by the total weight of the burning objects.
* Killing a wood golem with fire or burning more than a certain weight of objects on a square creates fire terrain on that space.
* Throwing burnables onto a fire trap may make them spontaneously combust and produce fire terrain.
* Fire terrain can be used to cook corpses.
* You can create fire terrain by applying a lit candle to a space with burnables on it
* You can also create it by applying a tinderbox to a space, which is a chargeable non-magical tool. Archeologists and Rangers start with one.
* Fires provide a light source of radius 3, but cannot be moved. Monster AI will not travel over fire if the monster is not resistant.

'''Air terrain'''

Extend air terrain to be used outside the Plane of Air, representing a chasm or abyss. If you step on air without levitation or flying, you fall to your death ("killed by gravity"), unless you're on the Plane of Air (where there's no place to fall ''to''). The obvious glyph is {{white| }} but wouldn't work because players are used to thinking of it as rock; other possibilities are {{white|~}} or {{white|#}}, or giving the player a warning when they would be stepping out into open air. Alternatively, don't let the player move into air terrain unless they confirm it.

'''Grass terrain'''

Ideas for making grass terrain ({{green|.}} or {{green|,}}) be an interesting piece of terrain:
* Dies and turns to normal floor if hit by fire or have a death ray zapped over it
* Turns into fire terrain if hit by fire and can spread to nearby grass
* You can plant trees on them, whereas you cannot do this on normal floor.

=== Other new terrain types ===
* A new type of "fence" terrain that is like wooden iron bars: it cannot normally be moved onto but it can be burnt or kicked down, and it does not block line of sight.
* Slope terrain, which is a terrain that appears like walls but does not block line-of-sight. It blocks movement unless levitating or flying, and cannot be dug down on or into. If you somehow get onto slope terrain (such as by stopping levitation while on it), you can move off it in any unblocked direction. This would allow interesting level designs like pyramids and switchbacks. Is still a bit problematic, since for things like a large pyramid, you would be able to see straight over the top of the pyramid and down the back side.

=== Changing terrain glyphs ===
Primarily to reduce overcrowding of {{gray|#}}:
* Iron bars and fences render as cyan/brown {{white|&#124;-}}.
* Sinks render as {{white|\}} (color unspecified, could be blue).
* Closed drawbridges render as some color of {{white|+}} which is not currently used by terrain - perhaps red or orange.
* Corridors could be moved to {{white|.}} but this would probably be very unpopular and make levels look a lot worse.
* Trees could be {{green|+}}, or possibly {{green|\}} to avoid spellbook confusion.
* Clouds could set the background color of a space and not change the foreground color, and could possibly be rendered with a blank space character, but this would probably have issues on non-color terminals.

|Many different thoughts centered around creating a bard role with distinct and useful gameplay:
* The bard and healer cannot both be focused around petmongering, so one of them would have to change. Most likely the healer, as the bard's traditional abilities are only good on pets.
* Instead of the standard little dog or kitten, the bard starts with a "party" of 3-4 player monsters, who are randomly chosen from other roles.
** This would make the primary strategy focused on having the party do the fighting for you, letting them level up, providing them with weapons and equipment, and not letting them die.
** Healers and archeologists, and possibly tourists, don't make very good additions to the party, and so should perhaps be ineligible.
** Party roles could be randomly chosen from distinct sets of "strong melee fighter" (Bar or Cav or Kni or Val), "ranged combat" (Ran or Rog or Sam or possibly Tou), and "spellcaster/cleric" (possibly Hea or Mon or Pri or Wiz).
** The party will not start with the full starting inventory of their respective roles. They will generally have the same weapons and armor, but will probably not have any of the scrolls, rings, wands they normally start with, and starting spellbooks should be either eliminated or unrandomized.
* YASI: the bard quest artifact gives party members the effects of their own quest artifacts.
* Healer strategy should shift away from petmongering - the easiest way to do this is change the protection formula in such a way that the protection racket doesn't exist; so that the player isn't incentivized to keep XL as low as possible until they can buy protection.
* Difficult for Healers to find a new niche. (Avoidance of combat is an option, but the [[User:Jonadab/ClassOverhaul|Class Overhaul proposal]] calls for Archeologists to fill that niche). Perhaps something that focuses on pacifying monsters by healing them, but this has issues: you shouldn't be able to ''tame'' by healing since that turns Healers back in the direction of acquiring lots of pets, and most monsters start at full HP and don't need any healing.
* Bards (and probably all players) should be able to equip their pets by #looting them, or a similar mechanism. (This would also apply to mounts.) Intelligent monsters will prefer player-given items above all others and will never willingly replace them for other gear. Possibly make this behavior dependent on options, because some players may want their pets to be pragmatic in their gear choices.
* Player monster pets should perhaps not be able to detect curses.
* Songbooks, + class items which contain a song that the bard can learn.
** Balancing the songbook generation rate against spellbooks might be tricky, because although bards can still cast spells and other roles can play songs, each is not very likely to have that much use for the other set of books. Hardcoding different probabilities based on whether the character is a bard or not doesn't seem very clean.
** Possibly the bard should be able to discover songs by trial and error, although simple brute forcing is definitely not the way to do it. Maybe all spellbooks start identified.
** The bard could need to practice the song by using the songbook in order to restore "song memory". Song memory does not work quite like spell memory, it works essentially like direct success rate. There might be some mandatory delay between practices, meaning you can't take an unlearned song and practice it up to 100% immediately. Or there could be a possible failure of practice, maybe a dexterity penalty ("Dumb move! You strain your fingers.") to serve to prevent practice-spam. Playing a song would serve to
** Spellbooks do not eventually go blank, and can be used for practice indefinitely.

Figuring out how calling object classes works might be tricky, because having it work as it currently does would mostly nullify the identification challenges of being colorblind.

|A new "illusion" monster spell, which makes the caster or an allied monster appear as another monster until something disrupts the illusion (you attack it, it attacks you, it takes damage from some other source). Monsters specifically cast it when you cannot see the target monster. The illusion favors nasty monsters, but low-level spellcasters may only be able to create illusions of somewhat higher level monsters. A potentially evil addendum is that high-level spellcasters may use the spell to make themselves or other powerful monsters appear to be weaker monsters.

|Ideas around a system in which you can cook corpses:
* The general idea is to unbreak the hunger system by making regular corpses unsafe to eat, so the shortage in resources isn't in food itself but is in safe methods of cooking it.
* Cooking sets a corpse's rot timer to 0, lets them go longer without spoiling, or unspoils them.
* May also remove poison from some kinds of poisonous corpses.
* Cooked corpses are unsuitable for sacrifice and less likely to give intrinsics, or don't at all (because the vitamins are destroyed).
* Can apply wands of fire to cook corpses.
* Or maybe eating raw non-vegetarian corpses is just plain dangerous, causing vomiting or sickness or other bad effects.
* Corpses can be cooked by killing monsters with fire or hitting monsters with fire attacks while they are carrying corpses.
* The problem is that nobody has yet proposed a mechanism for cooking corpses that would work well. Having firewood or some similar thing would massively affect the early game between characters that can and cannot manage to find it, and roles that start with or without it. Wands of fire have been proposed as a resource but those are valuable. Introducing a new item like firewood means that a whole lot of mechanics have to be reviewed for whether they should interact with or create that item.

|Invisibility works completely when the invisible monster and the detecting monster are far away. When within 5 (or 4?) squares of each other, its location is known to within 1 space (fuzzing the real location by 1 space in all directions). When the invisible monster takes a direct offensive action, or with some probability when it is adjacent, its position becomes known. It still appears as I, but the I will move wherever the monster goes until it becomes 5 or more spaces away, at which point invisibility once again works fully. This could work differently if the invisible monster is stealthy.

|Elaborations on the [[User:Ais523/Dungeon Overhaul Proposal#Fort Ludios|Fort Ludios minesweeper proposal by ais523]]:
* Should spaces with 0 neighboring mines get 0 gold? Good because it makes the game possibly more instantly recognizable as minesweeper, bad because it makes the overall amount of gold less predictable
* Need to guarantee somehow that the person stepping into the room doesn't trigger a mine instantly, and set up the level accordingly.
** The column nearest the entry door could be clear of mines and gold.
** The whole border could be clear of mines. However, this means that the total amount of gold must end up being an even number - not ideal.
* What happens if a monster steps on a mine?
* Possibly this needs an Oracle consultation to explain it to unspoiled players. Or make an engraving when you enter - possibly "xyzzy" as a reference to the cheat code in Windows Minesweeper. Or start off with one mine uncovered and identified on sight.
* The number of adjacent mines could be expressed in the ones digit of the gold amount. Possibly with a large round number added, so every space is 3001 or 2002, which hopefully clues the player into the fact that it's a significant number. But this might be too restrictive.
* How to reach the magic number 69105, and do so in a way that guarantees it can be generated? May need to bias the level generator so that this must happen.

To compute your total light radius, add up all the lumens and take the square root.

|Several improvements to the level-defining des files:
* General goal is to be able to get the MAP as close to pasteable into the wiki as possible.
* Interpret < and > on the MAP as STAIR commands for that specific spot.
* Interpret ? on the MAP as "terrain to be filled by this level's filler algorithm". (This would allow for things like Asmodeus' Lair to not have to be chunked into multiple pieces).
* Allow ^ to be placed on the MAP, and it is an error if there is no TRAP command for that space (the parser will assume that ordinary floor should be the type of floor). Same for + and DOOR, and for boulders.
* Allow monsters' inventory to be specified.
* Allow objects to be specified by random appearance, with a flag that defines whether it will pick a random item or simply fail to generate if that random appearance does not exist in the game.
* Allow the level size to be specified so that ROWNO and COLNO are out of the question.
* Extend 3.6.0's REPLACE_TERRAIN to work with non-rectangular areas.
* Most importantly, parse the files with something not written in yacc, because this adds an additional layer of complexity to anyone who wants to work with the code.
* Maybe even read in the .des files at runtime, so they can be modified without doing a recompile of them and the intermediate .lev form isn't even needed. This would require giving each level its own .des file and distributing them with the game. This means you don't get the benefits of using a parsing library, but you no longer have to code for or depend on that library either.

|Attempts to analyze good instadeaths versus bad instadeaths (loosely defined as ones that are instant hard-to-avoid deaths that aren't really similar to running out of HP):
* Poison, digestion, lava, death magic, and drawbridge instadeaths can easily be converted into HP damage of max(damage dice roll, substantial % of your max HP).
* Drowning and choking would be well-suited to a breath system, where it becomes a delayed instadeath. Especially so if you can stop the clock by putting on an amulet of magical breathing or praying.
* Intelligence drain and level drain generally can't happen without the player being given ample time to escape, so they are fine.
* Starvation could be changed to HP loss, but you usually just die from side effects of fainting anyway.
* Instadeaths that almost always have to be intentionally caused by the player (self-genocide, divine wrath etc) are generally fine as-is.
* Instakilling artifacts are problematic, because there is currently no recourse except for the amulet of life saving.
* Eating or digesting the Riders should not instakill without warning, because it is now unexpectedly a bad idea to eat a reviving corpse, whereas it had been a good idea in the rest of the game.
* Good instadeaths generally use unusual resources to fix, or hit the player's reserves in an unexpected way, and allow the player a chance to get out or stop it before dying.

(Breathlessness seems like a potion effect more than a scroll effect, but then again, during those times when you need emergency breathlessness, you're probably not capable of quaffing a potion.)  If you read any of the water, earth, fire, and air scrolls while confused, it summons elementals, whose tame/peaceful/hostile state depends on the beatitude of the scroll.

If you read it while on the Plane of Water, it either creates a new air bubble if you're not in one, or expands your bubble permanently if you are in one. If cursed and in a bubble, the bubble shrinks to one space.

|Gods' "Prove thyself worthy or perish" message is flavored as "Prove thyself worthy, because I can do no more for you". On the Planes, the gods' balance of power prevents your deity from granting you any extra help (apart from sending angels when you arrive in Astral).

|Change the sickness instadeath to a HP-based form of damage, since it is very obscure about how long you have left to live and can be drastically reduced.
* Instead of a death timer, apply a penalty to HP regeneration rate, with this penalty being variable and slowly decreasing as you recover from the sickness. This is nice because it allows for monsters to have a sickness attack in the early game.
* This penalty can be large enough to make your regeneration rate negative.
* Getting hit by a sickness attack while already Ill not only increases the severity/duration of your illness, it deals some extra damage proportional to the severity of the sickness.
* Severe enough sickness only partially times out - you will need to take some actual self-healing action like quaffing healing potions, praying, casting cure sickness, applying a unicorn horn, etc. to be completely cured.
* Unicorn horns no longer cure the entire illness all at once - they will only reduce the severity (which might cure the illness all at once if it's mild).
* Being sick for a long time may cause vomiting, Con loss, Str loss, and occasionally hallucinations.
* Sickness will eventually go away on its own if it's not bad. Maybe look to FIQHack zombification disease for specific mechanics for how this could work.

|Attempting to move healers out of the petmastering role: they now have skilled medical knowledge that enables them to hit monsters in melee with a scalpel or knife to inflict a "bleeding" status effect which will cause the monster to lose HP continuously. Any role is able to do this with a scalpel, but the effect is much more limited than it is for Healers. This means that for a Healer, combat now consists of hitting a monster to make it bleed, then disengaging and keeping away from it in the hope that it dies on its own. The Staff of Aesculapius no longer drains, instead it heals the damage it would have dealt (unless the Cyclops has it, in which case it drains life like normal.)

|When killed by a monster that brings you back as something else (zombie, vampire, green slime), you might not die; you may continue playing in that form with permanent intrinsic unchanging. This might make it actually beneficial to get killed by a vampire, so the chance of continuing can't be 100%, or else it can only work in a limited set of mostly-uncontrollable circumstances (like maybe a vampire's or zombie's bite takes you down to exactly -1 health). Green slime death is probably okay to stay at a 100% chance, though. Also needs some thought for how the unchanging squares with being a vampire and wanting to #monster into different forms. Perhaps intrinsic unchanging, unlike extrinsic, allows a monster to change into its normal alternate forms, but nothing else. Some other downsides should possibly be present too, like you don't get your normal amount of HP and are stuck with the amount given by your new form.

|The ascension run through the Dungeons of Doom (the instant you come back into your god's sphere of influence) is trivially easy: your god will regularly smite any enemy that dares attack you, and will ignore prayer timeout when answering prayer (but only to fix problems; if timeout is not 0, the god will not grant you any boons.) However, once you reach the Planes, the other gods step in and start interfering with the god so that they can't directly help you anymore. These other gods don't want to kill you since you're still bringing the Amulet closer to them. But when you reach Astral, the other gods will do all they can to kill you, relieve you of the Amulet, and bring it to their own high altar. Your god sends you several A (might be Aleaxes, ki-rins or possibly even Archons) instead of just one, but you are now faced with elite teams of player monsters, priests, and A sent by the other gods, who have amulet-stealing attacks. The gods' struggle to each get the Amulet manifests in all sorts of ways: disintegration beams blasting at you but being redirected onto a hapless monster nearby, inventory cursing, lightning bolts, resurrecting the corpses of dead player monsters or priests, and so on.

|New slot for ''belts'':
* Belts themselves could be armor or tools, but probably armor. They mainly serve to hold items for quick access. It's not defined whether they are intended to hold an indefinite number of items like any container, or a limited amount. The only problem with making them armor is that they would by default be enchantable for more AC; belts should probably not be enchantable. If it makes more sense that several magical belts would hold charges, tools would be the appropriate class.
* Items carried in a belt weigh nothing and are mostly or totally protected from destruction, and using them doesn't take the action it usually takes to get an item out of a bag.
* Types of belts could be scroll-holding, potion-holding, wand-holding, ammo-holding (with a possible "endless quiver" item or artifact), gem-holding (to get partial resistances from certain gems), chastity (providing immunity to foocubi seduction) or no special powers but some moderate AC. 
* One randomized belt description could also provide protection against leprechaun theft.
* Randomized descriptions could include: cloth, leather, worn, studded, buckled, braided
* Tourists and Convicts also start off with garish swim trunks/striped slacks, which do the same things as Hawaiian shirts/striped shirts. The swim trunks also allow swimming. Both of these protect from instadeath when you sit on a cockatrice corpse.
* Belts of giant strength, elven grace, and troll toughness. These increase your Str/Dex/Con either to 25 or by +enchantment (if belts can even be enchanted, which isn't currently defined.)
* Swordbelts/sheathes. These allow you to ready an additional weapon or give you an additional weapon slot.

* Luckstones don't remove luck timeout, they merely extend it.
* Luck is much less controllable, impossible to get any clues about except through enlightenment, and various random events (like what?) can give or remove luck. A skilled player would know how to bias the odds towards luck-increasing events. Controllable sources of gaining luck like sacrifice and throwing gems at unicorns are removed. It no longer times out.
* The luck timeout rate is less predictable, and a luckstone will help but it might still time out quickly if the RNG hates you.
* The base number that luck times out to is equal to the total number of luckstones in your inventory (so carrying 2 noncursed luckstones means luck times out to +2). Luckstones' weight is increased.
* Remove luckstones in favor of an amulet of luck. Luck timeout can no longer be slotless.
* Luck times out at a rate of 1 point per (600*(number of luckitems + 1)) turns.
* Do away with luck timeout entirely in order to make it impossible to micromanage luck. Luck is now conferred entirely by luckitems. The problem with this approach is that NetHack has about two ways to gain timing-out luck and many, many ways to lose it.
* Luck can be gained by enchanting luckstones.
* Different types of luckitems which stack with other luckitems but not with each other, like a four-leaf clover you can get from leprechauns.

Alternatively, make saltwater not an actual potion, and just use saltwater as a flavor reason for why the player can't intentionally dilute potions to water.

Also, make most potions cancel into non-water base potions (such as confusion and hallucination to booze), with the notable exception of polymorph.

|Merge the damage versus small and damage versus large stats of weapons, since they don't really matter that much and add mostly pointless complexity. Damage should be more dependent on skill than on the size of the target monster. The only problem is how to stop the highest-damage weapons from becoming used by everyone because they're so optimal; perhaps skill should do something drastic like add an extra die with every skill level, allowing you to have weapons that are decent at low skill (by having multiple small base dice) but poorer at high skill (because adding more small dice doesn't work as well).

* When carried, gives extrinsic monster detection. Farlooking reveals enemy HP.
* Invoke for precognition: for the next 100 turns, your attacks never miss, and enemies roll twice against you and use the lower result.
* If you would be killed from HP damage from an attack during precognition, you will dodge the killing blow and all subsequent attacks on that round. Immediately ends the effect.
* Might mesh well with the other encyclopedia idea, using it as a base item type.

|Condensing all of NetHack's poison mechanics into one unified mechanic:

* Poison is now implemented as a timing-out trinsic. The amount of Str loss is a direct function of how much timeout is left, so Str will gradually recover as the poison goes away.
* Passing Con saving throws could give small bonuses to decreasing the timeout faster than normal.
* While poisoned, HP regeneration is either impeded or stopped entirely, or else the player's HP is damaged every turn, or every several turns.
* It could also heavily abuse Str while it lasted instead of being directly tied to Str.

|Credit cards act as holding containers for gold. Not literally, but if you have credit in a shop and apply the card towards the shopkeeper, they can put the credit on your card, which you can then use to pay at other shops. Paying with a credit card has a 3% transaction fee, minimum 1 zorkmid. Each card also has a "credit limit" which is the maximum amount of gold you can put on it. Randomly generated cards may have some (small) preexisting balance on them, but you might get the Kops called if you try to pass it off as your own, or if you pay with a cursed credit card. A possible evil extension is that occasionally your card is invalid because the owners took all the money and fled to [other roguelike]. Priests and demon lords cannot be paid in credit. Gold that you have on a credit card doesn't count towards score. Killing a vault guard zeroes all your credit card accounts.

* Alternatively, unless you wish for nothing (which makes the demon lord vanish forever), the demon lord will immediately become hostile, making it an unlikely tactic in the early game.

*# Hit a monster at polearm range (skill-dependent).
*# Attempt to hook a monster at polearm range. Tame monsters are always hooked. Peacefuls are always hooked, but may be angered. Hostiles might be hit instead of hooked. If the monster is hooked, it will be pulled towards you, or you will be pulled towards it if it's much larger than you.
*# Grab the top item from a square, even if the square is a trap or water square.
* Wielding one passively gives a boost to the radius in which pets will follow when you change levels.

|You can #pray at a gravestone, or possibly ring a bell at one, to cause any of a number of good and bad effects:
* Summon a ghost, which might be hostile or peaceful.

* Polymorph you into a zombie or mummy of your own race.
* Put you to sleep, ignoring resistance.
* Create a swarm of hostile manes or lemures.
* The headstone falls on your foot, dealing some damage, less if wearing boots.
* If the grave is a bones pile grave, the ghost of the player always appears. It will be peaceful if their alignment matched your own and hostile otherwise.
* Various cosmetic messages that do nothing. "The air suddenly turns cold." "The engraving on the headstone shimmers for a moment."
* The dirt cracks open and spits out any items buried under it.
* A voice from nowhere whispers a random rumor, true or false.
* The epitaph on the grave changes. This does not flag the grave.
* Get an alignment bonus for honoring the dead (this is only if triggered by #praying). "You feel that the one buried here is content." Bonus might be larger if you're lawful or a Priest, probably 1 otherwise. This should possibly happen before and independently of any other effects.
* Limited identify of 1 item.
* Type-identify of multiple un-type-identified items in the inventory, but the player doesn't get to pick which. Might pick 0 items (flavored as the spirit not knowing anything new about what the hero is carrying).
* Enlightenment.
* Temporary telepathy / sleep resistance / infravision / other intrinsic.
* The gravestone rumbles and moves aside, revealing a branch staircase to a just-created-now one-level branch, a small one-off "crypt" floating branch that contains some undead, some boxes containing corpses, and some treasure.
* You "feel that the dead are restless", aggravating monsters level-wide. All gravestones on the level become flagged against further attempts. This effect could be added to and independent of other ones, and if so, it's a chance dependent on the number of already flagged gravestones on the level, which provides a nice way to balance it on levels that have massive amounts of gravestones.

After you get one effect, the gravestone is flagged so that it doesn't happen again (or, more evilly, that any further attempts will only result in bad effects). Possibly shouldn't work at all on graveyard levels, because they have too many graves to balance these effects.

|Various alternate endings for the game:
* You can take over an abandoned shop, stock it with items and mimics, and settle down as a new shopkeeper, ending the game. This creates a bones file with you replaced by a shopkeeper bearing your name.
* You can eradicate the Wizard of Yendor from the game entirely and forever, becoming the next Wizard of Yendor yourself. This is done by standing in the center of the Wizard's Tower wearing the Amulet of Yendor and invoking it. This respawns a beefed-up Wizard; defeat him and the game ends with you as the next Wizard. (It's missing an end condition for what happens if you escape the dungeon while in this semi-powered-up state.)
* You can claim the Amulet's power for yourself rather than giving it to a god. While anywhere on Astral, invoke the Amulet while wearing it. You get some big and unspecified surge of power from it. Furious at your betrayal, your god smites you every way they can, joined in by the other gods and the Riders, calling to bear all their priests, angels and Archons, which spawn in swarms on the high altars. (You also lose sanctuary.) You have to reach each high altar and shut it down/destroy it. Once you have done this, you win and keep the Amulet's power for yourself, as long as you can manage to hold on to it. 
* Alternatively, there is another way to do the "claim the Amulet for yourself" way: once you invoke the Amulet, a timer starts. The gods have only this much time to kill you or take the Amulet away before you become invincible to them. Would require some anti-boulderforting measures though. Or, you have to escape the Astral Plane back to the surface wiht all the gods trying to impede your progress.
* You want to break the power of the Amulet so no one gets it, and break the gods' dominion over the world. You must #invoke the Amulet while standing on each high altar to destroy it. (Not mutually exclusive with the other ending: you don't channel the Amulet's power into yourself, but into the high altar. In a game with both endings, you trigger the other one by invoking it anywhere except a high altar.)

|Remove fainting and direct starvation as a game mechanic. 
* In its place, just permanently and repeatedly decrement the hero's Strength or Constitution while they are in the Starving range (when nutrition <= 0) until the hero dies from stat loss. 
* The reduction happens when you hit -N nutrition, and it gets reset to 0 when this happens.
* Permanent reduction is done by reducing the current ''and highest-reached'' values of the stat by 1, so restore ability won't restore its full previous value.
* Since Fainting was pretty lethal already, the interval between losing points should be pretty short.
* When you eat something, before adding the nutrition from the food, your nutrition resets to 0.

|A bunch of scattered ideas for handling candles, given that the hero almost always wants to have only one lit at a time:
* Track all candles separately unless they have the exact same number of turns remaining.
* Merge all candles automatically, but still keep track of each one's lifetime. (This would enable lighting multiple candles and then having one of the stack burn out.) When you light part but not all of a stack, the game internally picks the shortest candles.
* When candles merge, their lifetimes are averaged together.
* You can't light more than one candle at once at all.
* When candles merge, the candle with the shortest life automatically sacrifices as much of its lifetime as needed to "top up" the rest of the stack. That is, if the lifetime is 400, a candle with 50 turns remaining will merge with a candle with 375 turns remaining, making a stack of 2 candles with 25 turns remaining; when those 25 turns are up, it becomes a stack of 1 candle with 400 turns remaining.

|Weapon differentiation - possibly a replacement of the old D&D "damage vs. small / damage vs. large" system currently in use. Weapons would do the same damage regardless of what size the target is, but might get a damage bonus or penalty based on if the target is vulnerable or resistant to piercing, slashing, or whacking/blunt weapons. Being resistant to this weapon type means that the damage is halved; being vulnerable to it means that the damage is multiplied by 1.5. Some obvious examples:
* Most undead are resistant to piercing damage. Skeletons are additionally vulnerable to blunt damage.
* Thick-hided animals are resistant to slashing damage.
* "Blunt is best against hard things, slashing is best against soft things, piercing is best against fleshy things"

|Various ideas to give the bonus from certain sources of speed only as a bonus to movement, not to getting more turns to attack, use items, etc.
* First, to classify: most agree that speed boots, intrinsic speed, and steed speed should be sources that only give extra movement opportunities, while polyform speed should give extra full turns. Less agreement on magical sources of very fast speed (the potion and haste self), but general opinion seems to be that these should also not be limited to movement.
* Add a second pool of movement points that coexists with regular movement points, but can be used ONLY for moving. Speed boots and its fellow sources add to this pool, and any unused points in it are discarded at the end of the player's turn. When you make a movement, points are deducted from this pool before being deducted from the "core" pool. Note that this approach can cause core points to accumulate to the point where the player can eventually get multiple non-movement actions on their turn.
* Reduce the movement point cost if you are taking a movement action and have sources of movement-only speed. (This might interact oddly if general-purpose sources of speed continue to add movement points as usual.)

|Bringing back different types of keys for different sorts of locks.

In particular, this third one could be used in Gehennom to block off areas, with "soul keys" or something similar that open special doors there and are generated with demons. Gehennom doors could also involve a blood ritual requiring some sort of expenditure of resources or damage to the player.

|Improvements to secret doors:
* When the player discovers a secret door, monsters still don't know about it unless they see it open.
* Monsters know about some secret doors in their native area, and will use them. If the player sees a monster using a secret door, it becomes unhidden. The proposed implementation for this is to have some monster types (the Wizard, angels, etc) have full knowledge of all secret doors everywhere, and all other monsters have a bit that represents whether they know about secret doors, which sometimes gets set when they are generated and always gets set when they see some other monster use a secret door.
* There are fewer or no hidden doors between the upstairs and downstairs on a Dungeons of Doom level.
* Less of a Dungeons of Doom level's loot appears on a direct or near-direct path between staircases, and more of the loot appears in rooms hidden behind secret doors.

|While you are on the ascension run, mimics prefer to disguise themselves as upstairs. It also edits your memories to make you think you remember the stair being where the mimic was.

|You can only use cursed potions of gain level once or twice while carrying the Amulet. After a few uses, it will start to pull you back down as you rise up, wasting the potion.

|The Staff of Necromancy: a quarterstaff artifact that deals double damage to non-drain-resistant creatures (but doesn't life-drain them as the Staff of Aesculapius does), grants cold resistance and curse resistance when wielded, and can be invoked to raise one vertebrate corpse on your square as a tame skeleton.

|Internally mark all of your starting gear with a special flag; if you die before receiving the quest, any items marked with this flag get degraded when placed into your bones pile: things like magical armor becoming nonmagical, wands lose charges, scrolls may fade, and spellbooks are made too faint to read more than once.

|-
|At the start of the game, three artifacts are selected as potential divine gifts, and you will never get any other artifact than these three by regular sacrificing. These three artifacts must not hate the player's race and ideally will provide a good balance in terms of power and utility. Gods can also grant non-artifacts as gifts, which no longer count against your odds of receiving an artifact. Also, the chance of getting an artifact is biased against low-level characters who have not made many sacrifices and towards high-level characters who have.

|Placing bag-of-holding-explosion-causing items into a bag of holding blows up the item that is trying to be placed inside, but does not harm the bag itself. If the item causing the explosion is a second bag of holding, its contents end up inside the outer bag.

|Pressure plate traps that cause all the doors of the current room to close and lock (doorways without doors could turn into iron bars or, on deep enough levels, all doors could turn into iron bars). Triggering this automatically removes the trap. Generated very rarely, and has special generation that occasionally makes it appear just inside a door to a throne room.

|Some monsters can block being detected by your telepathy, either innately (disenchanters, perhaps) or as a monster intrinsic conferred by armor (such as a tinfoil hat) or spellcasting by an ally. Also, possibly allow for area-of-effect "telepathy dead zones".

|Add several types of tape, which can be applied to mute yourself. While mute, you cannot cast spells, but you have a chance of not speaking the incantation when you read a scroll (resulting in the scroll becoming identified but not used up; none of its effects happen). There are four types of tape which randomly generate: Scotch tape (generating blessed 75% of the time and cursed 25%), packing tape (always uncursed), duct tape (50% blessed, 50% cursed), and Flex Tape (25% cursed, 75% uncursed).

Tape may fail to prevent you from reading a scroll, with a message "The magic of the scroll forces your mouth to move against the tape." followed by the normal scroll reading messages. The chance of this happening is 2% if the tape is blessed, 12% if uncursed, and 50% if cursed. When taking off blessed tape, there is a 75% chance you take it off normally, but a 25% chance that you rip it off instead, dealing 2 damage. When uncursed, there is an equal chance of taking it off, ripping it off, and having it be stuck on your face. When cursed, there's a 99% chance that it's stuck on your face, but a 1% chance that you tear it off, dealing 15 damage. Every ten turns you spend wearing tape, it might fall off on its own (5% chance), falling on the floor. Finally, every time you put on or take off tape, there is a 15% chance that it lose its stickiness, fall off if you put it on, and turn into an "odd strip of material", which can be used as a blindfold. Odd strips of material cannot be generated randomly.
