Lessons learned the hard way

History

Lessons learned the hard way was a huge Rodney entry. It was so large that it had to be removed from the database because Rodney would become unresponsive to everyone else whenever someone requested the entry. For a while it was hosted by GreyKnight, but now that the wiki exists we can put it where it really belongs.

You die...(again)

The Lessons

• Don't crush peacefuls in the Castle drawbridge, even if you don't want a red naga to fry you under conflict. The resulting bad luck can make your wished-for blessed magic marker come out cursed. The resulting cursed scrolls of charging will discharge and waste your wand of wishing.

• Levitation does not protect you from the kraken in Rodney's moat.

• Even though you're fire resistant and put on that ring of levitation to get out of the lava, you'll still die instantly when your legs get stuck.

• Don't try cancel your own spellcasting by pressing Escape, especially when polypiling. Skipping the direction prompt releases the magic power to the previously used direction!

• When you get a blessed scroll of genocide, @ means you, even when you aren't a human.

• Forcing the lock on the chest with a blunt weapon on the castle level isn't the best idea. Kicking it isn't such a good idea either, if the object you're expecting happens to be made of glass or crystal.

• Sleep rays bounce, and elves don't start with sleep resistance.

• Beware the hallucinating pet arch-lich. (Make sure that that black light over there blows up in your face and not your pet's.)

• "huh. Didn't know a bag of tricks would explode a bag of holding."

• You have to really be INSIDE a temple for sanctuary to work. The door isn't good enough.
  • Commentary: Unless the monsters are inside the temple too.

• Don't eat wraith corpses when satiated. You don't get a warning.

• Don't wear levitation items until you need them. They deprive you of Elbereth and other useful escapes.

• If you just spent a year extincting/genociding everything and then polypiling gems, hauling them to the first floor, trying for hours to get your giants arranged around the upstair, and Rodney comes...for the love of God, don't quaff the potion of gain level he may drop on death without checking BUC first. Lives have been ruined that way.

• Levitation spells don't cut it on Medusa's Island. Find a permanent source.
  • Commentary: With escape spells at skilled or expert the spell is equivalent to a blessed potion of levitation giving 250-299 turns of levitation, which should be sufficient. At unskilled or basic this spell may give you as few as *10* turns.

• Be wary of statues in the Gnomish Mines...

• Don't bring a pet gremlin to Medusa's level.

• Don't panic. Always know where your towel is.

• Don't EVER tangle with Cyclops, the Healer quest nemesis, in melee.
  • Commentary: Magic cancellation has no effect on the Staff of Aesculapius' level draining attack.

• Be very careful with uncontrolled teleportitis in stores!
  • Commentary: Drop your gold first.

• Plains centaurs in the mirror are stronger than they appear.

• Baby silver dragons don't reflect zaps of cold that you shoot at them. Looks like it's going to storm!

• Hitting e instead of w can be a fatal mistake when you have a cockatrice corpse.

• Just because you beat Sokoban and got a bag of holding, it doesn't mean you're invincible.

• Remember, "Thou shalt not worship graven images"

• Never sacrifice something you can't touch! Attempting to lure a cockatrice onto an altar for sacrifice with the idea that you can do so without touching it will cause you to develop a stony appearance without any chance of eating a lizard :(

• Never eat tins in shops whilst wielding potentially expensive artifacts.

• Using waterwalking boots on the plane of water will result in you drowning. Levitation, on the other hand, will work safely.

• Always use up cockatrice eggs you lay. Tame cockatrices turn any golem to stone golem, which is hard to kill.
  • Commentary: Or store the egg in a container until it is no longer hatchable after 200 turns. It will still petrify when you want to use it.

• Cursed athames aren't good items to engrave with.

• Don't carry wands/scrolls/potions outside bags. Nothing like standing on the vibrating square with the Bell of Opening (0:0), complaining about exploding wand of cancellation and wand of wishing and not having a scroll of charging handy.
  • Commentary: Or at least minimize the vulnerable items you have out. It is worth risking a few Escape_items to have them ready when you really need them.

• Don't rely on your quest artifact as the only source of ANYTHING.

• Don't stand on ice when there are foes with fire attack around.

• Don't try to disarm/disarmor your Archon with F command when polymorphed into a nymph. You can untame it.
  • Commentary: Instead, enchant its new armor better than what it's currently wearing, and drop the armor in front of your pet. It will change once it eventually picks it up. Weapons are a bit trickier: A bullwhip is a safe way to disarm your pet. To keep it from swapping artifacts, you want it to drop as many items as possible before you give it its new weapon.

• If you have crappy ISP, NEVER reconnect to server right after you got your internet connection back. There can still be some glitches with it.

• NetHack doesn't know about arrows/function/home/end/page up/page down keys and treats them as escape. Therefore DON'T TRY TO EDIT YOUR WISHES WITH THEM.
  • Commentary: (Only NAO lets you clear the input with escape.)

• NEVER have potion stack directly on altar when there are intelligent foes. Wand of striking == BOOM!

• NEVER skip messages with space. Ever. Especially when handling petrifying monsters.

• What do you think amulet of life saving is for?

• When polypiling, be careful with where you aim. In particular, don't hit that damn chest with goodies - if it polymorphs into non-container, ALL CONTENTS ARE LOST.
  • Contents are always lost on polymorph, but the container has a 5% chance to resist the polymorph beam. (95% for the Wallet of Perseus in SLASHEM.)

• When you have laggy connection, NEVER type next command before you see how previous one ended.

• When running from a nasty monster, go back the way you came.

• Be careful of what items are marked as 'y' and 'n' in your inventory to avoid confusion with yes/no prompts. For example, trying to eat something on the ground while levitating by typing 'ey' quickly will have disastrous effects if your inventory contains 'y - a cockatrice corpse'.
  • Commentary: Watch out in the spells menu too, double tapping "y" and casting a spell without seeing which one it was could put you in an interesting predicament. Was it FOD? Poly? Or maybe extra healing?

• Be careful of what items are marked as direction-moving keys in your inventory, in case you miss a key, so instead of 'ahky' (apply h-a key north Unlock the door? yes) you hit 'aky' (apply k-a wand of cancellation Really break your wand of cancellation? yes)

• When hiding in a shop to recover HP, make sure to rest instead of search to avoid finding (and waking) mimics.

• When breaking wands for its area-denial purpose, DO NOT break a wand of lightning unless you hate your rings.

• Especially not when Demogorgon is on the level. Not even if double-meleeing arch liches.
  • Commentary: the Wizard of Yendor and his clone are better examples, since arch-liches are resistant anyway.

• Make sure comestibles (esp. rubber chickens) aren't assigned 'e', wands aren't assigned 'z' or 'a', potions aren't assigned 'q', scrolls and spellbooks aren't assigned 'r', tools aren't assigned 'a', weapons that might be cursed aren't assigned 'w', armor that might be cursed isn't assigned 'W', rings that might be cursed aren't assigned 'P', etc.

• Wield the [[|cockatrice|cockatrice corpse]] when you're already in position to attack (you won't be moving into any unknown squares). Otherwise you will fall into a spiked pit on your way to your victim.
  • Commentary: and be instantaneously stoned. Any pit, trap door, or hole will have the same effect. If there is an item, you can check for known traps with the ^ command.

• When the ground around you looks the same except for being a different color, examine it with / or ; before stepping there.

• Don't anger your god after getting divine protection. Praying for unholy water on a crossaligned altar, for example.
  • Commentary: Unless you can afford to buy it back. (Unholy water can also be manufactured via confused blessed remove curse or dipping potions of water into fountains.)

• Don't go below dungeon level 18 or so without a means of crossing water. Falling past Medusa through a hole can really ruin your whole day.

• Don't melee cockatrices if you're polymorphed, especially if you are a vrock, master mind flayer, vampire lord, dragon or any other biting monster.

• Don't try to polymorph a merely annoying monster just to get it out of your way; save your charges (or mana) for things that are just about to kill you; the creature it becomes might be something deadly. (StormEagle, blue jelly => ice devil)

• Drop your gold, bag of holding, and unicorn horn on another square before #sitting on a throne.
  • Commentary: It is only necessary to drop your bag of holding or unicorn horn if your luck is zero or less, in which case they could be cursed. See throne for more details on exact throne effects and precautions to take.

• If you find Minetown bones, before you go #chatting up the priest, make SURE both the priest and the altar are of the same alignment.
  • Commentary: Also make sure that the temple isn't haunted. There is no way to fix that.

• If you have no gloves and are blind have recently dispatched a cockatrice, always move with the 'm' key. Doing so will cause you not to automatically feel objects on the ground.

• If you levelport, angry shopkeepers are somehow able to levelport with you.

• There is a vital difference between '<god> is displeased' due to praying too soon, and praying on the wrong altar or with negative luck/alignment. Only the first one makes your god angry.
  • Commentary: Is this really true? Also, a water prayer on a cross-aligned altar will make your god angry.

• Any monster in the 'follower' category will follow you through portals created by the Eye of the Aethiopica.

• If you are being held/crushed by an owlbear, zapping down with a wand of digging is not as effective as you might think. Engrave Elbereth with it instead...

• If you leave skeleton keys (but not lock picks or credit cards) lying around, monsters that can open doors are smart enough to pick them up and unlock doors with them.

• If a fountain in Minetown reduces to a trickle, cease using it immediately.

• For beginners: if your HP shows as yellow or red (with the HPcolors patch), you have the spell of healing and you have enough power to cast it, do so. You'll never know which gnome has the wand of lightning/cold/fire.
  • Commentary: Of course, if said gnome happens to have a wand of death it won't matter anyway.

• If someone throws an egg at you, it might have been a cockatrice egg - don't skip through the messages about stiffening and turning to stone as if they were ordinary battle spam, if you don't want to become a statue.
  • Commentary: Cockatrice eggs are the only eggs monsters ever use.

• If you don't have a way to protect against touch of death, NEVER step off of an E-square when facing an arch-lich.

• If you're trying for #conduct weaponless, just leave pick-axes on the ground. Don't even bother to put them in your BoH. Use wands of digging instead (which are not wielded). If you're going for #conduct pacifist, wield a cream pie and never let go. Rely on 5 to move.
  • Commentary: (Unless VERY careful: this means thinking for 5 seconds before every move.) You can remap the movement keys to use 5 or m in order to cut down on accidents.

• Never underestimate a bones level.

• While trying to tame something using charm monster that can resist, you'll probably gain a lot of pets. Naming them *all* will help keep you from sacrificing a pet (since corpses retain names) and losing your 50 points of protection.

• Get a second or third opinion. ALWAYS.

• Don't eat anything while standing on Medusa's corpse. You WILL fatfinger it and suffer a legendarily stupid stoning.
  • Commentary: Watch out for footrices as well. Green slimes are less dangerous.

• Always kill shapechangers when you see them. If you don't they turn into bad things that will kill you. (argiopeweb -- Minotaur in Soko3)
  • Commentary: (Demin -- Black Dragon Gnomish Mines lv 2) (RegalStar -- Archlich in Soko4)

• Don't stone-to-flesh statues from a bones file. They are likely to be well-armed and armored.

• If a human zombie dies on your altar during a sacfest, move the human corpse away before trying to sacrifice anything.

• If you see any messages pertaining to a swamp, do NOT blithely skip along the level. You WILL hit the water, and all your stuff WILL get blanked.

• Monsters will follow you through your quest portal. Engraving on the portal square doesn't work.

• If you're dipping potions into a fountain, don't typo and dip your bag of holding. The RNG will curse it. Every time.
  • Commentary: You can dig down on a fountain to make a pool of water, which is much safer to work with.

• Wielding a cockatrice corpse around a foocubus is an excellent way to get a permanent hard-on.
  • Commentary: A charisma of 20 will allow you to tell the foocubus not to take your gloves off. Don't click too fast though.

• Don't try to feed a dragon unless it is currently tame. If it is peaceful, thrown food will anger it.
  • Commentary: Food can only be used to tame dogs, cats, and horses, including their puppy / large stages.

• Zapping a high priest/priestess on the Astral Plane with a wand of teleport in order to move them off an altar DOES NOT WORK. It makes them angry instead, even if they were peaceful beforehand.

• Don't just try on unidentified rings if you're near a priest or any other friendly "@". If that ring turns out to be conflict, you won't live to regret it.
  • Commentary: Unless you know it isn't conflict. Other powerful or threatening peacefuls, not just "@", are also to be avoided, though trying on an unidentified ring near a weak peaceful is a good way to identify conflict.

• Locking a door will not do much if you leave a pick axe or mattock immediately outside it.
  • Engrave Elbereth under the pick, since all digging monsters respect that.

• Never, ever, ever jump near your quest leader. Your quest portal will be removed, with only one way to salvage your game: the Eye of the Aethiopica. Better hope you're a neutral non-wizard. It also helps to be able to cast charm monster with a relatively low failure rate.

• When in Sokoban, and you are at the fringe of death, do not try to teleport away using a scroll of teleportation. Sokoban is a no-teleport area, which will result in a few more hits from that monster you are trying to flee from, possibly resulting in your death.

• When you solve a Sokoban level and open the door at the end of the hall, it will be packed with monsters. One might just be a Nymph who will charm you, steal your wand of death, fail to teleport then use it on you.
  • Instead, displace a pet inside, or fight diagonally at the door because monsters are less likely to zap you at melee range.

• When attacking a gas spore, make sure your pet isn't within the range of the explosion when the spore dies. It will count as if you killed the pet.
  • Commentary: Unless your pet can survive the 4d6. This also applies to aligned Priests - losing the only co-aligned temple in your entire dungeon is a real bummer.

• If you want to create Excalibur in Minetown, make absolutely sure that there are no watchmen around (or that you have a pet strong enough to deal with them). Even if they aren't in sight, they will somehow sense you and get angry at you, and killing them count as murder.

• Don't try to polymorph at experience level 1 or 2, unless you like being killed by unsuccessful polymorphes.
  • Commentary: The polyself bug is one reason you might actually want to do this.

• Don't zap your kitten with a wand of polymorph. It may die from shock and you will have killed it.
  • Commentary: (System shock). Prefer a polymorph trap - it will not kill, and you can retry indefinitely.

• If you genocide giants before you do the Valkyrie quest, you will get lots of titans instead. You don't want lots of titans.

• Before you kick in a locked door, make sure it's not attached to a shop, lest you anger the shopkeeper.
  • Commentary: Check for the "Closed for inventory" engraving outside the door.

• In Moloch's Sanctum, be sure that you have entered the temple, and that the high priest has called you an infidel, before killing him. If you don't, you'll get dinged for murder.

• Don't eat meatballs while satiated, you won't get a warning!

• Don't polymorph in > direction while riding. Even your ki-rin is not invincible, A's are vulnerable to system shocks!

• Watch where you kill the Wizard the first time. Killing him above the moat is a VERY VERY bad idea if you can't swim.
  • Commentary: A way to fill the moat like a scroll of earth, wand of cold, frost horn, the spell of cone of cold, or access to white or silver dragon breath attacks will resolve the problem. The invocation artifacts and the Amulet of Yendor will always rise to the surface.

• When waiting for monsters to show up and force you out of were-form, don't wander away from your only weapon just because you couldn't carry it.
  • Commentary: Try throwing that weapon upwards.

• After you're done dancing with nurses or foocubuses, DON'T FORGET TO RE-EQUIP YOURSELF!

• On that note, be sure to remove all armor AND weapons before reverse-genociding that swarm of nurses.

• A xorn will gladly munch your Magicbane, especially when you disrobe to take a bath and blank scrolls.

• When you're on a level with water or lava, and you have uncontrolled teleportitis, and your connection is laggy, TREAD LIGHTLY.

• If you've altar scummed for Magicbane as a wizard who started with a ring of slow digestion, don't forget that you can actually use it to engrave an E-square when you're facing giant ants -_-
  • Commentary: Magicbane, not the ring of course ;).

• Be careful about wishing for cross-aligned/cross-class artifacts when low-level or low on health, especially when said artifacts are intelligent.

• When playing with number_pad off, be careful when going northwest. "Really attack Izchak?"

• When in a zoo, fight shriekers and gas spores last.
  • Commentary: If you can avoid kill them, yellow lights, black lights, freezing spheres, flaming spheres, and shocking spheres should also be left for last.

• Standing on a burnt Elbereth and reverse genociding dragons to create DSM is a great idea... unless you have uncontrolled teleportitis.
  • Commentary: In that case, go to Sokoban and use an Elbereth cage.

• Pause every time you see a monster. Watching the contents of your inventory, or what you are polymorphed into, is free. Thinking of a tactic is also free. Going toe-to-toe with a footrice when you're poly'd into a master mind flayer is priceless.

• After spending hours of hard work and effort to descend into Gehennom, only to be swamped by monsters, remember to check your status as often as your inventory. Scrolls of genocide may be great escape items, but only if that umber hulk next to you isn't looking your way!
  • Commentary: (And no, your AoLS will not save your sorry self here!)

• Werecreatures are considered human. Sacrificing werecreatures is good idea only if you are chaotic or playing an elf/orc/dwarf.

• AVOID foocubi of opposite gender when levitating over water in Medusa's level using boots. Drowning is not kinky.
  • Commentary: A charsima of 20 will force the foocubi to ask, but watch out for typos.

• Chameleons leave brown corpses. They can also impersonate monsters which leave brown corpses.

• If you drop your weapons and armor to go for a scroll-blanking swim in the castle's moat, please take care where you leave those items lying around. Chasing down a master mind flayer that's made off with your +7 Grayswandir is not fun when you're unarmed.
  • Write several Elbereth the dust below the items.

• When you get to the castle level, do not burn Elbereth on the drawbridge and fight the monsters there. A wand of striking will kill you instantly, and it won't be fun.

• Destroying a drawbridge with force bolt kills everything in the same way as closing it. Including you.

• Even if you've been struggling with containerless inventory management for 10,000 turns, and you've finally got a bag of holding from a wish, don't get all excited and just throw everything into it. That pesky wand of cancellation will go in last, and then you're screwed.

• If your luck is negative, or even if you think it MIGHT be negative, DON'T WISH UNTIL YOU FIX IT!

• If you're confused in a shop and standing next to the shopkeeper with your very promising character, keep doing nothing for as long as it takes. Yes I know it's only a 1 in 8 chance. Yes it will kill you.
  • Commentary: The same may happen for blind characters without telepathy. The m prefix to movement commands is only safe if you can detect the shopkeeper, even as I - you will say "Pardon me" instead of attacking.

• Plugging the trap doors on the Castle level with boulders is a Bad Idea. It will result in the lower levels being inaccessible, except through a controlled level teleport.
  • Commentary: You cannot dig downwards on the castle level. Leaving even one trap door open is sufficient.

• A bugle is not a good tool for a knight to use to wake sleeping monsters - especially in the Minetown.

• Never use force bolt in a level with a shop (you hear the chime of a cash register) if you haven't explored the area in the direction you're shooting if you can't pay for broken things, unless you can fight the shopkeeper.

• Never eat an unknown tin whilst hallucinating. It WILL be cockatrice meat.

• Engraving with wands is useful. If you get the message "The bugs on the floor stop moving!", more often than not, it will be a wand of sleep, but rarely it can be a wand of death. Don't zap it on walls that can reflect back to you. It will be that wand of death.
  • Commentary: All walls reflect rays. Death and sleep can be distinguished via price-id.

• If Branchport into Fort Ludios, you may very well land in the area just outside the inner keep and get swarmed by everything. While it's (generally) not a fatal error, it can still get rather annoying when you can't deal with about fifty creatures one-on-one.

• Training escape spells by repeatedly casting "jumping" is a sound strategy -- except in Sokoban. Especially if you plan to zap your wand of wishing soon afterward.
  • Commentary: Jumping in Sokoban carries a -1 luck penalty. You don't get dinged if you press escape at the prompt where you want to jump.

• Don't polymorph an air elemental in Slash'em. You will get a very fast baby dragon that is even more powerful.
  • Commentary: Also applies to vanilla, and the resulting monster will be that fast only for 1 turn.

• Do not pray on an cross-aligned altar when you are starving. You stomach won't change, but your prayer timeout will.

• When you accidentally get snakes from a fountain, run. Don't fight, run.

• In SLASH'EM, yes, you *can* sacrifice the Hand of Vecna. And yes, this gets rid of it permanently.

• Go ahead - leave auto-pickup on. It's handy until you walk over that footrice corpse without gloves.
  • Configuring pickup_types or better yet autopickup exceptions gives you the best of both worlds.

• Be careful if you have suffered amnesia. Although not remembering the exact layout of a level while climbing the dungeon with the Amulet is annoying, what's more annoying is forgetting that ELAM EBOW is a scroll of enchant weapon, deciding not to identify it first, and then reading it while wielding your blessed +7 Grayswandir.
  • If you get mind-flayed very often, it helps to collect a specimen of everything in your stash, to mass-identify.

• Don't mess with player type characters on the Astral Plane. Yes, there's only a small chance they'll be spawned with the Vorpal Blade. Yes, there's only a slight chance that the Vorpal Blade will instantly behead you. The RNG will kill you. Every time.

• Don't fight the Soldier Ant. Just don't.

• In NetHackW (graphical version) please remember to turn off auto-pickup. It's nice until you find a statue. You whonder why you can't pick up anything when You see here 57 gold coins. There is nothing here to pick up. Or You see here a statue. You can barely move a hand's reach with this load!
  • Commentary: Or set pickup_types, or pickup_burden. Or compile in and set autopickup exceptions.

• Be sure to identify wands before zapping them at enemies, especially if you're zapping an unknown wand of make invisible at a nymph!

• Stand back when casting fireball unless you want your pets and belongings to burn.

• For crying out loud, don't kick down doors if they have an engraving in front of them! Even if it's ??o?? f? I???t???.
  • Commentary: A bones level may have a pre-eroded engraving. Or you may have stepped on it and not noticed.

• If you find a dead end, don't hold down s. It'll just make things worse if you encounter a monster and are still searching.
  • Commentary: Use a numeric prefix instead, like n10s or just 10s if using vikeys.

• When you find a small mimic in a shop, be sure to attack it, not the shopkeeper! There's no way to say that you meant to hit the mimic!

• Similarly, when attacking a mimic with wands or spells, check your rebound path every single time. The shopkeeper does not stand still while you're fighting.

• When playing NAO, if you get lag, don't just keep pressing buttons, once the prompt has stopped lagging, I guarantee you will have the message, "Do you want your possesions ideantified? [yn](n)"

• If you're multi-tasking with NetHack, be sure you're in the chat box with your friend(s) and not still on the NetHack command prompt. "r u playing nethack again?" yes (y: Unknown extended command e: What do you want to eat? [acdsR-?*] s: A cockatrice corpse. Do you want your possessions identified?)

• Engraving with your fingers in the dust is fine unless your Elbereth happens to be E¦bereth.
  • Commentary: Always, always check your writing with :. Six intact dust-E will guarantee at least one will survive the smuding on the turn you move off.

• Just because you survived that rolling boulder trap DOES NOT mean you or your pet will survive it again.

• If you fall through a trap door into a vault without a pickaxe, don't keep saying that your name is Croesus, the vault doesn't have a kitchen, refrigerator, or any other type of food producing place that you'd find in your house.

• When casting force bolt, be sure that there are no pets, shopkeepers, guards, etc. behind what you're hitting.

• Don't put every single damn piece of armor, gloves, or shoes you find on! Sure they might not be cursed, but when you do put them on, they'll be cursed. Every single time!
  • Commentary: (Unless you have the spell of remove curse and enough power.)

• When it comes to genociding (Master) Mind flayers, if your a dwarf ... enough said ...

• Make sure to remove that ring of conflict you might be wearing before you enter a shop.

• Eating a chickatrice corpse does not make you petrification resistant.

• If your kicking things off traps, make sure you aren't low on HP, and are strong.

• And also remember to press k if you want to kick things off a rolling boulder trap in the Gnomish Mines

• When surrounded by resurrecting rock troll corpses, don't quaff an unidentified potion. It will be polymorph, and you will become a grid bug.

• In SLASH'EM, make sure you beware creatures hiding under items. It could be a deadly asphynx, which has the ability to petrify you and cause an easy-to-miss YASD.

• Unless you are in immediate danger of dying, don't break an unidentified wand. You may be killed by a blast of magic.
  • Commentary: Most of them blast you for some amount of damage dependent on their charges. Many of them have secondary effects like teleportation or slowing.

• Even if you happen to be wearing a ring of polymorph control, don't try to polymorph (quaffing sinks ...) when you are a low level (like XL1) - you risk death from system shock or from level drain after feeling like a new man/elf/orc.
  • Commentary: polymorph control protects you from system shock, but you still have a 8% chance of fatal level drain.

• If the RNG gives you another bag of holding after you already have one, leave it alone. Don't carry it around as a spare. You will space out and try to put one of them in the other.
  • Commentary: Hauling it to your stash is good, but do so carefully, and possibly on a separate trip. Alternatively, putting both bags in a sack of oilskin sack will eliminate the possibility of typos.

• When trying to get crowned so that your god will give you a spellbook of finger of death, make sure your luck is actually maxed before casting create monster a couple hundred times.

• When you've been fighting hordes of monsters as a master mind flayer, remember that your stomach is now quite full. Do not try eating anything, especially a randomly generated newt in the lower levels of Gehennom just to try and get that one extra point of power for the heck of it.

• If you enter an area (say, perhaps the zoo on the way to kill the Wizard) with cockatrices and weapon-wielding monsters (say, perhaps a troll), back off and make SURE you've got a lizard corpse handy in your inventory. Be a good Boy Scout and always be prepared.

• Carrying around a lot of potions in your main inventory is a bad idea. You will step on a magic trap and die when a blast of fire causes all of your potions to boil and explode right after you've wished for blessed +3 silver dragon scale mail and the Master Key of Thievery.
  • Commentary: They are too heavy to carry around, anyway.

• So wait, I'm NOT supposed to use that fireball scroll while hallucinating?

• Don't eat eggs unless you're sure of what's in them. Just because you haven't seen any cockatrices yet, doesn't mean the egg is safe.

• Don't bang on the keyboard, you'll just be angrier.

• And don't rest on the keyboard as well!

• Have a laptop? Move carefully!

• Attacking a floating eye isn't fatal...unless there might be a powerful monster nearby...

• Collecting useful items from bones files is great! Reading/Using anything immediately after isn't.
  • Commentary: BUC first.

• Yes, pressing any directional key counts as 1 turn, no matter what! (Except for trying to move into a wall or solid rock.)

• Just because your laptop doesn't have a numpad, doesn't mean you cant move diagonally. Then again, normal numbers hate laptops that play NetHack. Especially if your confused.

• The castle level is a cruel, cruel place... Trust me...

• Don't try to play 2 NetHack games at the same time. Just don't.

• Skip the Gnomish Mines and come back when your more powerful, or, you wont get past level 3 of the main branch and die in the Gnomish Mines.
  • Commentary: If you're playing as a Gnome or Dwarf most of the monsters will be peaceful.

• If your listening to music while playing NetHack, don't, don't, DON'T press buttons (especially directional keys) to your music, you'll miss your YASD.

• In SLASH'EM as an ice or flame mage, don't youpoly into a dragon when you are wearing armor. Unlike lycanthropes and doppelgangers, you will break out of it. And unlike regular polymorphs into them, your dragon scale mail is not preserved.

• Don't even try to read spell books at level 1.
  • Commentary: Wizards will get a warning if the book is too hard, so long as it isn't cursed. Blessed books are safe.

• Remember, look, don't touch!

• Organized pack helps. a - primary weapon, d - pick axe, g - unicorn horn, etc. Arrange to taste.

• After clearing a screenful of monsters involving c, leave for a few hundred tics, to let the corpses expire.
  • Commentary: Or pick all of them up and use for yourself or safely put away -- but be sure you're wearing gloves! Corpses almost always rot after 250 turns.

• Finding a blindfold from a bones file while having intrinsic telepathy is great! Now don't get all excited and immediatly after just to "try it out", because you'll be "trying it out" much longer that you'd like.

• Archons' dazzle is incredibly annoying - lenses are nearly worthless
  • Commentary: Lenses do not stop an Archon's gaze attack, only blinding acid and raven claws.

• Get greedy, get killed.

• Don't try that genocide scroll until you've BUC tested it! A room full of Liches at level 3 leads to YASD!

• A throne room full of dragons is fantastic for intrinsics but take your damn time in eating them. They're a lot to choke down and it sucks to find out that you have just choked on your disintegration resistance.
  • Commentary: Killing and eating them one at a time is good. A tinning kit will also help. They are larger than most other corpses.

• Do not walk around Minetown blind for easy guard murder as a chaotic until you can smite a leocrotta in one hit. The Watch Captain hits hard at lower levels. If not chaotic, wait it out.

• Blind yourself BEFORE walking up the stairs to Medusa's house if you've dug to avoid moving over her water. Else she will petrify you right away.
  • Commentary: Medusa is @. Elbereth won't stop her, even if you have time to burn it.

• If your spells spill over onto a second page, make sure that healing and finger of death aren't represented by the same letter.

• Be careful when BUC-testing items with a leashed pet. You won't necessarily get the "<Pet> moves only reluctantly" message--very bad if you then put on a cursed ring of conflict with no known method of removing curses handy

• Nethack is a good patience detector. Hurry equals death. Which can also be fun actually, if you don't mind not ascending

• NEVER use a figurine of a monster that might be strong enough to kill you without curse-testing it, unless really desperate. (And even if it is uncursed or blessed, there's still that 10% chance...)

• Despite an Archon being a very powerful and useful pet capable of dispatching many enemies on its own, it is not immune to being engulfed and digested.

• ^S (control + S), in some terminals and telnet clients (PuTTY for one), suspends output to your screen. Your keystrokes will go through, but the results won't be displayed yet. ^Q un-suspends it. ^I is an invalid command that happens to also be the tab key, if you want to test a "frozen" terminal, press this. Then try ^Q. DO NOT SPAM KEYS. You will, upon resuming your session, or killing your session and starting a new one--whether because it really is frozen or because you didn't know about traditional terminal flow control--that you have died.

• Using a cursed scroll of create monster to create sacrifice fodder is never a good idea.
  • Commentary: Though a confused one is handy at times (it will produce only acid blobs, good for blocking movement.)

• Just because you found a wand of wishing on DL 8 doesn't mean that a spotted jelly can't hurt you.
