A '''shop''' is a [[special room]] found on some dungeon levels. Each has an attendant shopkeeper and a selection of items to buy. The shopkeepers will also buy items from you, depending on the type of shop. A complete list is below.

A '''shop''' is a [[special room]] that appears in ''[[NetHack]]'', and may occur on some levels of the dungeon. Each has an attendant [[shopkeeper]] and a selection of [[item]]s to buy - the shopkeepers will also buy items from [[you]], and both types of items depend on the type of shop. A shop with no shopkeeper is considered abandoned.

==The shopkeeper==

==Generation==
−
A [[shopkeeper]] owns a shop and buys and sells the items within.
+
Shops have a base 3/[[Dungeon level|DL]] chance of being created on any dungeon level between level 2 and [[Medusa's Island]], with the exception of the [[Oracle]] level. The creation of a shop assumes there is a suitable room to put them in (i.e., no [[stair]]s, only one [[door]]) and that there are enough rooms on the level to start with - the minimum number of rooms required is 3 for normal dungeon levels, and 4 for a branch level. Note that this means that there will always be a shop on each of levels 2 and 3 if the conditions are right (which in practice turns out to only be the case about 45% of the time).

−
At first, shopkeepers seem skilled enough to prevent [[adventurer]]s such as yourself from taking anything without payment. However, many ''[[NetHack]]'' players know where shopkeepers are vulnerable; if [[you]] do not, see [[stealing from shops]]. Be sure you don't accidentally attack the shopkeeper!
 
−
 
 
−
=== Normal transactions ===
 
−
Normally, shopkeepers own all items on any square of the floor of their shop, with the notable exception of the square adjacent to the door, here called the "entrance square". Here we make a distinction between:
 
−
* the ''shop inventory'', the items on the floor of the shop.
 
−
* the ''shopkeeper's personal inventory'', the items which the shopkeeper is carrying; this often includes several dangerous offensive [[wand]]s.
 
−
 
 
−
'''Buying''': If you pick up such an item, you will have an unpaid object in your [[inventory]]. Press {{kbd|p}} to pay for the items; the shopkeeper will ask you about each unpaid object, and if you pay, you will own the object while the gold will transfer to the shopkeeper's personal inventory. If you have credit at that shop, it will be used first. You can #chat to get the price of an item on your square without picking it up.
 
−
 
 
−
'''Selling''': If you drop an item onto the shop floor (not the entrance square), the shopkeeper will offer to buy it if they normally carry that type of wares. If you refuse, or if the shopkeeper makes no offer, then you continue to own the item and can pick it up again without paying. Note that having an item unintentionally fall onto the floor will cause it to become theirs and you must buy it again, so it is generally a bad idea to eat tins in shops when you are wielding something.
 
−
 
 
−
'''Credit''': If you drop [[zorkmid|gold]] onto the shop floor, the shopkeeper will give you credit, which you can use to buy items. You can abuse the credit system through [[credit cloning]].
 
−

=== Shopkeepers are greedy ===
 
−
* Shopkeepers will own and sell anything on their shop floor. If you kill a [[monster]] in a shop, even if you had to kill it to save your own life, the shopkeeper will own any dropped items and the corpse. Likewise, if you eat fried food and [[Slippery fingers|drop your weapon]], it's theirs. If you throw an object, even if you had to throw it at a monster in order to protect yourself, again, the shopkeeper will own it. When you are in a shop, never kill a [[leprechaun]] that has stolen your gold or a [[nymph]] that has stolen an item, unless you like paying for what was previously yours. In the black market (in both [[Black market (SLASH'EM)|SLASH'EM]] and [[Black market (UnNetHack)|UnNetHack]] versions), dropped artifacts may reach ridiculous prices.
 
−
* Depending on your [[nutrition|hunger status]], shopkeepers will charge more for food: hungry x2, weak x3 and fainting x4{{refsrc|shk.c|2860}} (They even do this for corpses of monsters that you killed.)
 
−
* Shopkeepers will reveal the identities of non-magical [[weapon]]s and [[armor]] when you buy or sell them. For example, if you sell a crude dagger, the shopkeeper will reveal that it was an [[orcish dagger]]. These identities are the same during every game. What shopkeepers will never identify for you are [[scroll]]s, [[spellbook]]s, [[ring]]s, or other such useful information. Shopkeepers also never tell you about [[BUC]] status or [[enchantment]] (directly – though price can hint at an item's enchantment). After each transaction, they will tell you the item's appearance, in case you are blind.
 
−
* Shopkeepers will sell unidentified gems at high prices (as if all gems are valuable) while purchasing them at cheap prices (as if all gems are glass). So the most obvious way to identify gems by price does not work.
 
−
* Shopkeepers sell all [[artifact]]s at grossly inflated prices. Specifically, they charge four times the normal price.{{refsrc|shk.c|1917}} They are also stingy about paying for artifacts, only offering a fourth of the normal buying price.{{refsrc|shk.c|2853}} In practice this means one should almost always steal artifacts generated in shops, and should pretty much never sell artifacts to shopkeepers.
 
−
* You can attempt to calm an angry shopkeeper by pressing {{kbd|p}}. What then happens depends on how you angered the shopkeeper. If you angered them by walking out with unpaid inventory, covering that debt will calm them. If, however, you angered the shopkeeper by attacking them, you will first cover any debts you have to the shopkeeper. They will still be angry, but you can then try to calm them by offering them 1000 gold pieces (when you press 'p'). This has a 2/3 chance of calming the shopkeeper, but the money is taken either way. You can avoid the necessity for this bribe by walking out with an unpaid debt – doing so will make the shopkeeper 'forget' about the attack, and be calmed by your covering that debt. Of course, doing this takes time, during which the shopkeeper may very well kill you.
 
−
* If you teleport out with an unpaid item (e.g. [[teleportitis]]) and you have established sufficient credit for the item beforehand, the shopkeeper will not be angry, but all of your credit will be used up, however much it was. Thus, while when shopping with teleportitis it is a good idea to establish credit before picking anything up, it is best to price items by standing on them and #chatting, and establish only enough credit to cover the items you plan to pick up.

===Usage fee===
 
−
{{main|Usage fee}}
 
−
If you use an item with limited uses in a shop before paying for it and in the presence of a shopkeeper, you will be charged a [[usage fee]].{{refsrc|shk.c|3922|comment=usage fee}}
 
  
−
===Paying off angry shopkeepers===
+
With the exception of bones and [[Orcus-town]], shops are never generated abandoned, and are never restocked under any circumstances - the only way they can gain more items is if they are brought in by you, a dead player from a [[bones]] file, or very rarely another [[monster]].
−
If you stole items, you are guaranteed to pacify the shopkeeper by paying them. There will be an angry shopkeeper price hike, and you need to move adjacent to the shopkeeper unless you both are in his shop. Damaging their door or wall will immediately prompt you to pay 400zm, and you will always avoid angering him if you do.
 
−
 
 
−
In all other cases, you can pay them 1000zm for a 2/3 chance of pacifying him.{{refsrc|shk.c|1320}} In such a situation, it can be advantageous to steal something inexpensive so you can pay him off reliably, or to toss him a [[wand of magic missile]] to avoid his powerful melee attacks.

=== Notable shopkeepers ===

* [[Izchak]]

==Prices==
 
−
 
 
−
{{Main|Price identification}}
 
−
 
 
−
When you sell an item, typically you are offered half its base price.
 
−
 
 
−
When you buy an item, typically you are charged from half the basic price to twice the basic price, depending on your [[charisma]].  To be charged half the basic price, you need to have a charisma above 18.
 
−
 
 
−
If you are a [[Tourist]] below the experience level of 15, or wearing a [[dunce cap]], or wearing a [[shirt]] not covered by [[body armor]] or [[cloak]], you will be charged 4/3 of the normal price when buying and offered 2/3 of normal price when selling.
 
−
 
 
−
If the object (except a gem) is unidentified, in 25% of cases the shopkeeper will charge 4/3 of the normal price when you buy, and offer 3/4 of the normal price when you sell. The effect is cumulative with the previous effect.
 
−
 
 
−
When buying unidentified gems, glass is sold as if it is a precious gem. When selling unidentified gems, you will be offered 3-9 zorkmids for each one.
 
−
 
 
−
Positive enchantment increases the price of weapons and armor. You can use this to identify positive enchantments.  In particular, if one weapon or piece of armor is more expensive than another one of the same type, the former is either enchanted or it is the occasional 33% supercharge on unidentified items.
 
−
 
 
−
Water is the only thing whose price depends on its BUC status. It is 100 for [[holy water|holy]] or [[unholy water|unholy]] water, 0 for uncursed water (effectively, this means that you can buy uncursed water for about 2-16 zorkmids, and cannot sell it).
 
−
 
 
−
If the shopkeeper does not have enough gold to pay for something you are trying to sell (and which he wants to buy), he will offer "only" as much as he has. If the shopkeeper has no gold at all, he will offer credit, at 90% of the normal price.
 
−
 
 
−
Artifacts have their own base prices. Shopkeeper charge exorbitant prices when selling them and offer low prices when buying them. The ratio between the two prices is at least 16-fold.

−
In addition, the first shop generated in Minetown will always be a health food store when the player is a [[monk]].
+
===Special levels with shops===
 +
The following special levels are guaranteed to have shops at fixed locations:
 +
 
 +
* [[Minetown]] (except for [[Orcish Town]]) is guaranteed to have at least 1 shop, including [[Izchak]]'s lighting store. In addition, the first shop generated in Minetown will always be a health food store when the player is a [[Monk]].
 +
* The [[Tourist Quest]] has several guaranteed general stores: two in the locate level (The Thieves Guild Hall) and two in the goal level (The Shades).
 +
* [[Orcus-town]] is usually host to a few abandoned shops.
  
−
==Generation==
+
===Closed shops===
 +
Shops can also be generated "closed", in which case the message "Closed for inventory" will be written in dust outside of the shop door. The shop door itself will be locked. Breaking down the door will anger the owner unless you immediately pay 400 zorkmids; opening the door with an [[unlocking tool]], [[wand of opening]] or {{spell of|knock}} spell allows you to enter and shop as usual. Shops in special levels cannot ever generate closed.
 +
 
 +
===Mimics===
 +
{{main|Mimic}}
 +
Any [[mimic]]s you encounter are most likely to appear in shops, disguised as items. There is a (dungeon level - 1)% chance of a mimic generating on a given shop square instead of an item.
 +
 
 +
===Traps===
 +
[[Trap]]s cannot normally be generated in shops, with the exceptions of shops placed on special levels. In practice, this will most likely occur in the Tourist quest and Orcus-town - while the various layouts of Minetown contain two traps each, they are very rarely placed within any of the shops.
 +
 
 +
==The shopkeeper==
 +
{{main|Shopkeeper}}
 +
The shopkeeper is a [[human]] monster that owns the shop and its contents and buys and sells items within. They are responsible for the upkeep of the shop as well - this includes magically repairing most damage done to the shop's floors, walls and door, and removing most traps that are set within their shop(with the exception of [[pit]]s or [[web]]s), including those made by you. Damaged walls, broken doors and [[hole]]s are repaired in five turns.{{refsrc|shk.c|3033}}{{refsrc|shk.c|3043}} If the shopkeeper should end up dead for any reason, or else a shop has no shopkeeper, then the shop's items are free for you or any monster to take.
 +
 
 +
{{upcoming|NetHack 3.7.0|Shopkeepers will now remove pits and webs as well.}}
 +
 
 +
===Theft prevention===
 +
{{main|Stealing from shops}}
 +
Shopkeepers are 50% faster than a normal character's base [[speed]], and will keep close to their shop's entrance - this makes it difficult, but not impossible, to walk out with unpaid items. See the article linked at the top of this section for more information on how to steal from shops, and see the article on shopkeepers for more details about their movement.<!-- Please do not expand this section, go to [[Stealing from shops]] instead.-->
 +
 
 +
===Barring the entrance===
 +
In addition, shopkeepers will block the entrance square (the square inside the shop that is directly in front of the door) and will not allow you to enter their shop if you are [[invisible]], have a visible [[pick-axe]] or [[dwarvish mattock]], and/or are currently [[riding]] on a steed. If you dismount, become visible, or remove the digging tool(s) from your open [[inventory]] (including placing it in a [[container]]), you will be allowed entry. Note that the door of the shop is not considered suitable for dropping your digging tools - this is to prevent characters with extra speed from entering on a free turn. Shopkeepers will also catch any tools you attempt to throw in.
 +
 
 +
While in a shop, the shopkeeper will prevent you from leaving if you are mounted and/or invisible.
 +
 
 +
===Pick-axes===
 +
On top of the above, the shopkeeper will yell at you if you pull out a digging tool(s) from a container while inside - but this does not anger them, and you can safely sell or otherwise walk around with the tool(s) as long as you do not dig through the shop walls. Digging a pit will have them warn you about falling through [[hole]]s, though this will also not anger the shopkeeper - but if you dig again and create a hole, items on the same square and possibly adjacent squares will fall through.
 +
 
 +
Attempting to enter a shop with a dwarvish mattock or pulling one out inside a shop will also identify it.
 +
 
 +
===Angering the shopkeeper===
 +
The shopkeeper will become angry if you attack them, damage the shop or its inventory, or they see you leave with unpaid items or debt - additionally, if you try to leave the shop with unpaid items via a hole made within the shop's boundaries, the shopkeeper will try to [[Stealing from shops#Shopkeeper prevention|grab your pack]] as you fall if they can get adjacent. Theft includes any items on the same square as a hole falling through it, as well as items from potentially adjacent squares. Damaging the shop door or walls will immediately prompt you to pay 400zm for a door and 200zm for each wall segment destroyed, and the shopkeeper will be angry if you do not pay.  Damaging the shop from out of the shopkeeper's line of sight (e.g. with a [[wand of digging]]) will always anger them, with no chance to pay.  Note that the damages the shopkeeper asks for are not ordinary shop debt: refusing to pay will not make them "remember" how much you owe them, and escaping without paying the recompense will not summon Keystone Kops.
 +
 
 +
Leaving a shop with unpaid items will anger the shopkeeper; the items then become yours, their value (including a price hike if the shopkeeper was already angry) is added to your debt, and Kops are summoned.  It is then possible to pacify the shopkeeper by paying at least half of your debt{{refsrc|src/shk.c|1553|version=NetHack 3.6.7}}.  Unless you are currently in the shop, you will need to be adjacent to the shopkeeper or throw the required gold at them.  If you anger a shopkeeper without incurring a debt - e.g. by attacking them directly or damaging their walls or door - you can pay them 1000zm for a {{frac|2|3}} chance of pacifying them.{{refsrc|src/shk.c|1407|version=NetHack 3.6.7}}{{refsrc|src/shk.c|1420|version=NetHack 3.6.7}}.  Stealing an item while the shopkeeper is already angry due to such an offense and then paying your debt will make the shopkeeper "forget" about your previous offenses: they will become calm and return to their shop as usual, without taking 1000zm. Pacifying a shopkeeper by paying for stolen goods will also pacify any watchmen on that floor and cause any Keystone Kops present to disappear.
 +
 
 +
Note that "ordinary" shop transactions are handled before any attempt to pacify the shopkeeper: if you are in a shop with an angry shopkeeper while holding an unpaid item or owing them for a destroyed item, trying to pay them will first prompt you to buy that item, using up a turn.  For a low-level character facing an angry shopkeeper, that one-turn delay can be fatal, even if they otherwise have enough gold.
 +
 
 +
====Hot pursuit====
 +
Unlike other monsters, shopkeepers actually have two distinct "angry" states: they can be rendered hostile like any other monster, but they can also be put into a state referred to internally as "hot pursuit", which is tracked separately from standard hostility.{{refsrc|src/shk.c|1324|version=NetHack 3.6.7}} A shopkeeper who is merely angry will attack you if you are inside their shop, but will not leave the shop to pursue you, though they will still use any ranged attacks and block you from re-entering their shop. A shopkeeper in "hot pursuit" will chase you across the level; if they lose sight of you, they will wander like any other monster, rather than returning to their shop.
 +
 
 +
Shopkeepers who are robbed are angered ''and'' put into hot pursuit, as are those whose shop walls are damaged and those who are attacked from outside their shop. The most common way of angering a shopkeeper without causing them to pursue you is to attack them from ''inside'' their shop, and then escape without stealing anything; other more obscure methods include applying a [[drum of earthquake]]. It is possible for a shopkeeper to be in hot pursuit ''without'' being angry: this requires you to pacify an angry shopkeeper in "hot pursuit" with a [[magic harp]] specifically (since other methods of pacification remove the hot pursuit status).{{refsrc|src/shk.c|4261|version=NetHack 3.6.7}} In this state, the shopkeeper will follow you and periodically ask you to pay, with a {{frac|10}} chance of becoming angry again each time they ask.{{refsrc|src/shk.c|4269|version=NetHack 3.6.7}} If the shopkeeper was pursuing you because you attacked them or damaged their shop, it is impossible to pay them due to a lack of debt, and they will eventually become angry again if you stay near them.
 +
 
 +
==Transactions and inventory==
 +
A shop's inventory consists of all the items on any square of its floor, with the notable exception of the "entrance square" in front of the door; this is not to be confused with the shopkeeper's personal [[inventory]]. Items belonging to the shop will have their price displayed as you move over them, and an item's price can be also viewed by [[near look]]ing on their square. For containers generated as belonging to a shop, the contents are also that shop's property, regardless of whether that shop would sell them normally. You cannot buy from shops normally while [[blind]] unless you have [[telepathy]], as you will be unable to see the shopkeeper, although you can still sell items as normal.
 +
 
 +
Pressing {{kbd|$}} will display any [[#Credit|credit]] you have, along with any debts you currently owe the shopkeeper. You can #[[chat]] to get the price of an item(s) on your square without picking anything up. Buying and selling non-magical [[weapon]]s and [[armor]] will have the shopkeeper partially identify that item(s) to you - e.g., if you sell a crude dagger, the shopkeeper will reveal that it was an [[orcish dagger]]. After each transaction, they will also tell you the item's appearance if you are blind.
 +
 
 +
===Buying items===
 +
Picking up items off the shop floor adds them to your inventory, with each item(s) being given an "unpaid" tag that lists their price - pressing {{kbd|I}} and then {{kbd|u}} will display all the unpaid items you are currently carrying.
 +
 
 +
You can pay for your goods by pressing {{kbd|p}}, which will prompt you about itemized billing; answering "no" to this will pay for all the items at once if possible. For itemized billing, you can pay individually for each unpaid object (or stack of objects). Items that you pay for are yours, and the required gold will transfer to the shopkeeper's personal inventory. In both cases, if you have credit at that shop, it will be used up first before any gold is transferred.
 +
 
 +
===Selling===
 +
If you [[drop]] an item onto the shop floor (with the exception of the entrance square), the shopkeeper will offer to buy it if they normally carry that type of wares. If you refuse, or if the shopkeeper makes no offer, then you continue to own the item and can pick it up again without paying.
 +
 
 +
Any items that unintentionally fall onto the shop floor, e.g. from [[throw]]ing them or [[Slippery fingers|losing your grip on them]] will be considered "relinquished" and automatically sold if it is a type normally sold by the shop. Any items dropped by monsters killed within a shop also becomes that shop's property - this includes you, if you die while inside a shop.
 +
 
 +
===Credit===
 +
{{Main|Credit cloning}}
 +
If you drop any [[gold]] onto the shop floor, the shopkeeper will give you credit which you can use to buy items and pay off debts. If you sell an item to a shopkeeper that is completely out of gold, they will instead offer you store credit in exchange for the item at 90% of the normal price. Any credit given in a shop is only good for that specific shop - if you leave a shop with unpaid items in your inventory (e.g., your intrinsic [[teleportitis]] suddenly kicks in), ''all'' of your credit will be used to cover the losses, and if your credit was not enough, the shopkeeper will become angry.
 +
 
 +
You can abuse this credit system through credit cloning - see the linked article at the top of this section for more detailed information.
 +
 
 +
===Usage fees===
 +
{{main|Usage fee}}
 +
If you use an unpaid item with charges in a shop before paying for it and the shopkeeper is present, you will be charged a [[usage fee]].{{refsrc|src/shk.c|4580|version=NetHack 3.6.7}} Broken or destroyed items, including the locks of [[chest]]s and [[large box]]es, also incur fees.
 +
 
 +
==Pricing==
 +
{{Main|Price identification}}
 +
 
 +
===Base price===
 +
Each item in ''NetHack'' has a base price, which is modified in various ways to produce the final selling price; an [[artifact]] has its own usually-high base price distinct from its [[base item]]. Positively-enchanted weapons and armor have an additional 10 zm added to their base price for every point of enchantment.
 +
 
 +
Some items are considered "worthless"; you cannot sell them, but their buying price is calculated as though they had a base price of 5 zm:
  
−
Shops have a base 3/[[Dungeon level|DL]] chance of being created between level 2 and [[Medusa's Island]], provided there is a suitable room to put them in (no stairs, only one door), and provided that there are enough rooms on the level to start with (minimum 3, 4 for a branch level). Note that this means that there will always be a shop on each of levels 2 and 3 if the conditions are right (which in practice turns out to only be the case about 45% of the time).
+
* items with zero base price
 +
* [[cancelled]] [[wand]]s (with -1 charges)
 +
* partly-eaten [[comestible]]s
 +
* uncursed [[potions of water]]
  
−
The probability of a shop being of a particular type is given in the second column above.
+
====Unidentified gems====
 +
Valuable [[gem]]s and worthless glass which aren't formally identified have their base prices determined by a different mechanism:
  
−
===Closed for inventory===
+
* When buying, the base price is that of an arbitrary valuable gem.
−
Shops can be generated "closed", in which case the message "Closed for inventory" will be written in dust outside of the shop door. The shop door itself will be locked. Trying to chop down the door with an axe will give you the message "This door seems too hard to chop through."
+
* When selling, the base price is between 3 and 8 zm.
−
* Opening the door with a lockpick or key will not anger the shopkeeper, and you will be able to buy and sell as usual.
 
−
* Breaking down the door will anger the owner unless you immediately pay 400 zorkmids.
 
  
−
The shop remains closed permanently unless the player opens it using one of these methods.
+
The random modifiers to unidentified item prices listed below don't apply in this case. Even if you know for a fact that a gem is valuable (by e.g. [[engrave]]-testing) and have named it correctly, you can't get its full selling price unless you formally identify it.
  
−
Shops are never restocked under any circumstances. The only way they can gain more items is if you, or very rarely a monster, bring them in.
+
[[Gray stone]]s don't use this mechanism; an unidentified gray stone is priced the same as an identified one.
  
−
===Traps===
+
===Buying===
−
[[Trap]]s cannot be generated in shops. Exceptions are on special levels: the [[tourist quest]] and [[Orcus-town]].<ref>The [[Minetown#Frontier_Town|Frontier Town]], [[Minetown#Town_Square|Town Square]], [[Minetown#Alley_Town|Alley Town]], [[Minetown#College_Town|College Town]], and [[Minetown#Bazaar_Town|Bazaar Town]] layouts of [[mine town]] contain two [[trap]]s each. However, they don't seem to get placed inside shops.</ref> [[You]] can make traps yourself (such as [[pit]]s), but the shopkeeper will usually remove them.
+
When you buy an item, you are charged the base price, modified as follows. All multipliers are applied in sequence:
  
−
==Messages==
+
* Your [[charisma]] grants a modifier to the buying price.{{refsrc|src/shk.c|2134|version=NetHack 3.6.7}}
−
You can tell there is a shop on the level if you receive any of the following messages.
+
* Some characters are considered "suckers", and will be charged {{frac|3}} more. You are a sucker if:{{refsrc|src/shk.c|2128|version=NetHack 3.6.7}}
 +
** You are wearing a [[dunce cap]]
 +
** You are wearing a [[T-shirt]] or [[Hawaiian shirt]] uncovered by a [[cloak]] or [[body armor]]
 +
** You are a [[Tourist]] below [[experience level]] 15
 +
* A hostile shopkeeper will charge {{frac|3}} more.{{refsrc|src/shk.c|21g4|version=NetHack 3.6.7}}
 +
* When buying unidentified objects, in {{frac|4}} of cases the shopkeeper will charge {{frac|3}} more. This surcharge is tied to the individual item or stack; merged stacks will inherit the higher of the two prices, while split stacks will inherit the price of the original stack.
 +
* Depending on your [[nutrition|hunger status]], shopkeepers will charge more for food and comestibles:{{refsrc|src/shk.c|3402|version=NetHack 3.6.7}}
 +
** If you are hungry, the price is doubled.
 +
** If you are weak from hunger, the price is tripled.
 +
** If you are fainting from hunger, the price is quadrupled.
 +
* Artifacts are bought for four times their already-inflated base cost.{{refsrc|src/shk.c|2159|version=NetHack 3.6.7}}
  
−
{{message|You hear someone cursing shoplifters.}}
+
===Selling===
−
{{message|You hear the chime of a cash register.|There is a shop on the level}}
+
When you sell an item, you are normally offered {{frac|2}} the base price; charisma modifiers do not apply. If you're a sucker, as above, you are offered {{frac|3}} the base price instead.
−
{{message|You hear Neiman and Marcus arguing!|There is a shop on the level; you are hallucinating}}
 
−
{{message|This shop appears to be deserted.|There is no shopkeeper in this shop.}}
 
  
−
==Special levels with shops==
+
* {{frac|4}} of shopkeepers will pay {{frac|4}} less for unidentified objects; this modifier is consistent for a given shopkeeper.
−

{{For|shopkeeper-specific strategy|Shopkeeper#Strategy}}
 +
Shops are a very useful resource overall, particularly in the early and mid-game - they are usually a primary source of items and equipment, and additionally provide a means of identifying them via prices, as mentioned above. They can also serve as a place to offload anything you consider [[junk]], and can serve various other purposes besides.
  
−
Shops are extremely useful. As well as being a source of items, they let you do [[price identification]].
+
It may sometimes be worthwhile to drop your gold and use credit to buy things, rather than paying directly - even if you do not plan on shoplifting, you may benefit from tricking a monster into bringing the gold back to you. Covertly stealing expensive items (usually including artifacts) may also be worthwhile for the early advantage they provide, e.g. a powerful weapon, or something to sell back to the shopkeeper for a significant price.
  
−
'''Do not''' quaff any unidentified potions in a shop – it may be a [[potion of invisibility]], and if you do not have a [[mummy wrapping]] you will have to teleport out (recommended) or kill the shopkeeper (not recommended). This goes double for [[cloak]]s, as a [[BUC|cursed]] [[cloak of invisibility]] could significantly complicate your game.
+
===Shopping while invisible===
 +
If you are invisible and either do not want to wait until you are visible again, or your invisibility cannot be undone (either due to a cursed source or a [[quaff]]ed blessed potion), then you can use one of the following methods to safely enter or exit a shop as normal:
  
−
You can raise cash by selling [[junk]] and [[credit cloning]]. Know which objects are lightweight and expensive.
+
* Wearing a non-cursed [[mummy wrapping]] is the safest and most typical method, as it works in a mass majority of cases with the exception of a cursed [[cloak of invisibility|cloak]].
 +
* [[Teleport]]ing into and out of the shop is possible, but requires [[teleport control]] for you to enter reliably.
 +
* [[Jump]] diagonally through the door.
 +
* Hurtle diagonally through the door by throwing things while [[levitation|levitating]] due to Newton’s Third Law.
 +
* [[Dig]] down on the level above - but this leaves you completely at the mercy of [[RNG]].
 +
** You can also dig a hole out of the shop through the floor - this is safe as long as no unpaid items fall through with you.
 +
* You can forego entering entirely and instead use a [[pet]] and a [[magic whistle]] to steal from the shop.
 +
* Use any holes in the wall dug by a [[tunneling monster]] (e.g., a [[Dwarf (monster)|dwarf]] with a pick-axe or mattock); each hole will be magically repaired in at least 5 turns after it was made if no monster is present on that square.
 +
* [[Polymorph]] into a [[xorn]] to [[phase]] through the wall.
 +
* Be very fast (e.g. usually from wearing [[speed boots]]) and beat the shopkeeper to the door. Note that the shopkeeper will move to stay ahead of a player's intrinsic speed - this does not account for speed from polyself.
  
−
Unless you're completely averse to the idea of shoplifting, always drop your gold and use credit to buy things rather than paying directly even if you don't plan on shoplifting. There's always a chance that a monster will bring the money out for you.
+
These methods are less safe and/or may cost you some gold:
  
−
===Shopkeeper actions===
+
* Carry 800zm or more, then polymorph into an [[umber hulk]] or [[rock mole]] and chew through the wall, and pay for the damage.
 +
* Carry 800zm or more, then destroy the closed shop door, pay for the damage immediately, then enter/leave. The door will be fixed afterward.
 +
* Teleport the shopkeeper - but this will anger them, and you will have to avoid the shopkeeper on the way out unless you can pacify them.
 +
* Kill the shopkeeper, directly or otherwise - doing so directly counts as [[murder]], and you are deprived of price identification for that shop in either case.
  
−
Shopkeepers stay within a few squares of the entrance square to their shops. They move fast (speed 18, the normal speed of a character is only 12) and will always immediately move to the entrance square if you pick up an unpaid item (i.e. not one that you have refused to sell or they are not interested in), and if you are outside their shop and invisible or carry a visible digging tool (see below). This means that a very fast character can beat them to the entrance square, at which point you will receive a warning to pay for any items you haven't before you exit the shop.
+
===Shopping smart and safe===
 +
While each character's shopping needs will differ, price identification can generally narrow down what wares you may want to focus on, and even without thorough memorization a player can get an idea of which items are valuable.
  
−
Shopkeepers will not allow (a) invisible customers: ''"SHKNAME detects your presence. Invisible customers are not welcome!"''; (b) those with visible digging tools: ''"Hello PLAYER, welcome {again} to SHKNAME's STORETYPE! Will you please leave your {pick-axe(s)/mattock(s)/digging tools<sup>(if you have both)</sup>} outside?"'', (providing passive identification of your mattock if unidentified); or (c) those who are mounted on a steed:{{refsrc|shk.c|604|comment=steed}} ''"Hello, PLAYER, welcome {again} to SHKNAME's STORETYPE! Will you please leave your STEED outside?"'' into their shops. After speaking, a shopkeeper will then move to bar access to their shop.
+
There are other multipurpose pointers for a shopper to keep in mind - in general, ''never'' buy or sell gems that are unidentified.
  
−
To gain access, you need to wear a [[mummy wrapping]] or take off that [[ring of invisibility]] and drop or [[bag]] any digging tools you may be carrying. The door of the shop is not considered suitable for dropping your digging tools if you have extra [[speed]], to prevent people entering on a free turn. (Speed exclusively from polyself does not count.) You could retrieve them with a [[grappling hook]]. Shopkeepers do not check contents of [[container]]s, however.
+
In general, it is a [[Bad Idea]] to randomly wear or use items within a shop, since even if your pet is not averse to moving over them, you may end up endangering yourself or complicating play as you would with any randomly use-tested item - you may end up quaffing a potion of paralysis, wearing a helm of opposite alignment, exploding a cursed wand, or end up reading a non-cursed scroll of fire with the shopkeeper nearby and/or unpaid flammables in your inventory.
  
−
Leaving a shop by digging down is safe as long as no unpaid wares fall though. If you smuggle a digging tool in to the shop, when you take it out of the container, the shopkeeper will ask you to leave, ''"You sneaky {cad/minx}! Get out of here with that {pick/mattock}"''. If you then dig a pit in the floor, you get a warning, ''"Be careful, {sir/madam}, or you might fall through the floor!"'' but otherwise there are no ill effects – the shopkeeper does not become angry. If you dig again and create a hole, items on the same square will fall through, and potentially other items from the squares around your hole. If unpaid items fall through, this counts as stealing and angers the shopkeeper, who will try to [[Stealing_from_shops#Shopkeeper_prevention|grab your pack]] if he can get adjacent, and making it more dangerous to return to the level.
+
One particular obstacle to this end is the [[scroll of scare monster]] - a scroll that is cursed or has been picked up and dropped once turns to dust when picked up, which incurs a charge for the destroyed item. Novice adventurers who shop by picking up items can find themselves trapped in a store with no money and no way out. There is also the more direct threat to your life posed by mimics of any kind - even small mimics can end an unwary early character, and particularly unfortunate sorts may end up stuck to a giant mimic.
  
−
If you are [[blind]] without [[telepathy]], items can be sold but not bought. With telepathy, shops can be used normally.
+
There are several ways to prevent any mishaps while shopping:
  
−
====Methods of entering/leaving when invisible====
+
* Be sure #chat to a shopkeeper before picking up certain items directly.
−
* wear a (non-cursed) [[mummy wrapping]] (the safest and most typical method)
+
* Always carry a few hundred spare zorkmids to cover any accidental charges you incur. In a worst-case scenario where you cannot avoid incurring damages, you may need to sell some additional items in your inventory - depending on your situation, this may be preferable to being branded a thief or dying.
−
* [[teleport]] (requires [[teleport control]] to enter reliably)
+
* Before entering a shop, quaff a non-cursed [[potion of object detection]]. You may notice suspicious blank squares if you have not yet seen the contents of the shop - those are likely to be mimics.
−
* [[jump]] diagonally through the door
+
* "Obvious" out-of-place objects are often mimics, especially in specialized shops (e.g., a long sword in a potion shop, or down staircase in any shop). However, this does not work as well for general stores (which sell almost anything) and [[bones]] files (which may have the inventory of the dead player - although you may encounter signs of this beforehand).
−
* hurtle diagonally through the door by throwing things (e.g. rocks) while [[levitation|levitating]] due to Newton’s Third Law
+
* If you are playing with default tiles or standard ASCII, you can also discern mimics by their glyphs - they will appear as "strange objects", and the tiles for strange objects are chests with eyes peering out of them ([[image:strange object.png]]/{{monsym|strange object}} versus [[image:chest.png]]/{{brown|(}}). Additionally, their glyph is usually the mirror of the glyph for [[armor]] ({{cyan|[}}) - the only time {{white|]}} is used for anything else is for actual armor on the [[Rogue level]].
−
* [[dig]] down on the level above to (hopefully) fall into the shop, and leave by digging down on an empty square after [[pay]]ing
+
* [[Telepathy]] and [[warning]] will reveal mimics and/or their locations.
−
* instead of entering, use a [[pet]] and a [[magic whistle]] to [[steal]] stuff
+
* The [[ring of protection from shape changers]] will force mimics into their standard form.
−
* have a [[digging monster]] dig a hole for you to enter (e.g. a [[dwarf]] with a [[pick-axe]]/[[mattock]])
+
* Any form of [[monster detection]] can reveal mimics - note that a non-blessed [[potion of monster detection]] or a {{spell of|detect monsters}} spell cast at lower than Skilled level only reveals their current location, while detection from a blessed potion or Skilled (or better) spell passively remains active.
−
** the hole will close after 5 turns if the shopkeeper is not dead and no monster on the hole (“Suddenly, a section of wall closes up!”){{refsrc|shk.c|3033}}
+
* A safe and surefire way to uncloak mimics inside a shop is to throw a single gold piece across each row of the store - this does not use up valuable projectiles and will only establish credit. Be careful not to hit and possibly anger the shopkeeper!
−
* [[polymorph]] into a xorn and [[phasing|walk through the wall]]
+
* [[Search]] before walking onto an item to uncover any mimics - this will prevent you bumping into them, as the larger ones are sticky.
−
* polymorph into an umber hulk or rock mole and chew through the wall, then pay for the damage (risky!)
+
* A [[stethoscope]] can also uncover mimics, and the first application of a stethoscope per turn is a free action.
−
* raze the closed shop [[door]] (kicking, digging, striking without hitting the shopkeeper, what have you), pay for the damage immediately, then enter/leave
+
* Healing a mimic disguised as an item (e.g. via a [[spell of healing]]) will indirectly expose it, with the "object" seeming a more vivid color than before.{{reffunc|mon.c|mimic_hit_msg|comment=mimics give strange messages if healed while disguised}}
−
** only safe if you openly carry 400zm
+
* If you lack any means of detection and are risk-averse, only walk where your pet or the shopkeeper has walked.
−
** the door will be fixed in five turns, same conditions as a hole. (“Suddenly, the shop door reappears!”){{refsrc|shk.c|3043}}
 
−
* be [[very fast]] and beat the [[shopkeeper]] to the door.
 
−
** The shopkeeper will move to stay ahead of a player's intrinsic speed, but not speed from polyself.
 
  
−
Of course, you could always [[Shopkeeper#Ways_to_kill_shopkeepers_easily|kill or teleport the shopkeeper]] directly or indirectly, but that deprives you of [[price identification]] and counts as [[murder]].
+
===Combat===
 +
A shop can also function as a refuge if you need to heal or fight a powerful enemy. You can pick up an item and stand so that the shopkeeper blocks the door, preventing non-phasing monsters from getting in. If you stand a knight's jump from the door, you will not be exposed to ranged attacks from outside as well. You can then move next to the door to fight, and step away to heal at your leisure.
  
−
Due to a bug, you can leave a 2x2 size shop only with these methods. (Saving and reloading the game while standing next to the shopkeeper may alleviate this bug in a semi-sane and perfectly legal fashion)
+
===Zen shopping===
 +
{{main|Zen}}
 +
For zen players, shops are one of the few methods available to identify item the appearances, particularly scrolls and potions. However, being unable to see the shopkeeper poses a great danger: paying only works if you can see the shopkeeper, and failing to discern the shopkeeper's location by searching before safe-moving via {{kbd|m}} will nearly always result in death. It may be advisable to avoid shops altogether until you have telepathy.
  
−
===Robbing shops===
+
Braver and/or more experienced players can bring a container to place items in (ideally a [[bag]]) and a pet to steal the container back in order to speed up the process of re-acquiring sold items that the shopkeeper has identified. It is also possible to drop enough gold to cover your purchases and then teleport, jump or phase out after picking up your desired items, even without [[teleport control]] - unfortunately, this is not nearly as reliable early in the game, and most zen players acquire telepathy before any of these other methods become available. Selling items works as normal, and might be useful if you get burdened before acquiring telepathy.
−
{{main|Stealing from shops}}

 +
==History==
 +
Shops have been present in the game's code since the original release of [[Jay Fenlason's Hack]], and make a proper first appearance in Hack 1.21, a variant of this first ''Hack''. Hack 1.21 also included a shop at the beginning of the game, where characters purchased their starting items, rather than bringing their initial inventory with them into the dungeon.
 +
 
 +
Izchak and his lighting shop in Minetown were introduced in [[NetHack 3.2.0]] as part of a tribute to late DevTeam member [[Izchak Miller]].
 +
 
 +
In default installations of [[NetHack 3.4.3]] and earlier versions, along with some variants based on those versions, prices are not displayed by default, and you must pick up items or #chat while standing on them to learn their price. Additionally, modifiers for unidentified items applied to identified items as well, and the lower price for sold items was applied per-sale - by repeatedly dropping an item, refusing the shopkeeper's offer, and picking it up again, you would eventually get two different quotes. A bug was also present in those versions that could prevent you from leaving a 2x2 size shop through normal means; saving and reloading the game while standing next to the shopkeeper may alleviate this bug in a semi-sane and perfectly legal fashion.
 +
 
 +
The health food store was introduced in [[NetHack 3.6.0]]. Beginning in [[3.6.1]], [[autopickup]] no longer picks up unpaid items - this prevents any mishaps involving a cursed scroll of scare monster.
 +
 
 +
==Messages==
 +
{{message|You hear someone cursing shoplifters.<br>You hear the chime of a cash register.|There is a shop on the level.}}
 +
{{message|You hear Neiman and Marcus arguing!|As above, but you are hallucinating.}}
 +
{{message|This shop appears to be deserted.|There is no shopkeeper in the shop.}}
  
−
It's possible to steal from a shop with the help of a pet, or without. <!-- Please do not expand this section, go to [[Stealing from shops]] instead.-->
+
==Variants==
 +
Some variants may feature entirely different types of shops, in addition to adding more locations and/or functions.
 +
{{todo|Cover the rest of the variants eventually.}}
 +
===SLASH'EM===
 +
[[SLASH'EM]] adds pet stores, randomly generated light stores, tin shops, and music shops. SLASH'EM also has the [[Black market (SLASH'EM)|black market]], a special floor-wide shop with its own branch tended to by [[One-eyed Sam (SLASH'EM)|One-eyed Sam]] and his assistants. Shopkeepers are also much more powerful than in vanilla ''NetHack''.
  
−
===Scrolls of scare monster===
+
Shops can be additionally found in more locations as well - the [[Mall]] is a special level that contains several shops and can appear early in the dungeon.
−
Because a cursed scroll of scare monster turns to dust when picked up, novice adventurers who shop by picking up items can find themselves trapped in a store with no money and no way out. Wearing or putting on an unpaid for object (weapon, armor, blindfold, rings, amulets) to only find that it is cursed and hence cannot be taken off is not a pleasant experience either. If you cannot remove curse and cannot pay for that object, praying may work as a last resort. There are several ways to prevent these mishaps from happening to you:
 
−
*Use #[[chat]] instead of picking up scrolls.
 
−
*Always carry a few hundred spare zorkmids to cover any accidental charges you incur.
 
−
*As a last-chance option, sell everything you have to cover the cost of the scroll. Better to leave naked than in a coffin.
 
  
−
===Mimics===
+
===UnNetHack===
−
While [[mimic]]s may appear elsewhere in the dungeons, they are most likely to appear in shops, disguised as items. There is a (dungeon level - 1)% chance of squares getting a [[mimic]] instead of an [[item]]. Earlier versions of NetHack made them relatively easy to identify, but more recent versions have made them virtually indistinguishable from the rest of the shopkeeper's wares. Clever adventurers can still identify mimics:
+
[[UnNetHack]] also contains pet stores, randomly generated light stores, tin shops, and music shops. The [[Town]] branch is a new addition that contains a few shops, including most of the newer ones.
−
*[[Search]] before walking onto an item.
 
−
*A [[stethoscope]] is better than searching, as it will not unhide the mimic.
 
−
*A mimic can be healed while disguised, provided it is disguised as an item (as opposed to a dungeon feature for example). This will result in a message such as "The boulder seems a more vivid gray than before."{{reffunc|mon.c|mimic_hit_msg|comment=mimics give strange messages if healed while disguised}}
 
−
*[[Quaff]] a non-cursed [[potion of object detection]]. You may notice suspicious blank squares if you have not yet seen the contents of the shop.
 
−
*Throw a single gold piece across the store. If it hits the wall, nothing in its path was a mimic. This is better than throwing items because you don't automatically sell gold. Be careful not to hit (and possibly anger) the shopkeeper.
 
−
*Wear a [[ring of protection from shape changers]]. This will cause mimics to appear as mimics.
 
−
*Use [[telepathy]], [[warning]] or [[monster detection]].
 
−
*If you don't have telepathy and can't chance being attacked by a mimic, a less effective method is to only walk where your pet or the shopkeeper has walked.
 
−
*Use common sense: A long sword in a potion shop is probably a mimic. A down staircase in any shop is a mimic. This method is least useful in general stores and stores in bones files.
 
−
*In the graphical system, if you see a chest that has eyes, then it is a mimic: [[mimic]] [[image:strange object.png]]/{{monsym|strange_object}} versus [[chest]] [[image:chest.png]] / [[armor]] {{cyan|[}}.<!--Do we want to warn about ] being armor on the Rogue level?-->
 
  
−
===As a combat tactic===
+
UnNetHack also contains its own version of [[Black market (UnNetHack)|the black market]], with the same layout as SLASH'EM - UnNetHack's [[One-eyed Sam (UnNetHack)|One-eyed Sam]] is a woman, and there is a second possible map that instead splits the market into several independent shops with their own shopkeepers, while One-eyed Sam herself keeps watch.
−
A shop can function as a refuge if you need to heal, or to fight a powerful enemy. Pick up an item and stand so that the shopkeeper blocks the door; monsters from outside cannot get in. If you stand a knight's jump from the door, you will not be exposed to ranged attacks from outside. Move next to the door to fight, and step away to heal.

Revision as of 16:47, 10 March 2024

A shop is a special room that appears in NetHack, and may occur on some levels of the dungeon. Each has an attendant shopkeeper and a selection of items to buy - the shopkeepers will also buy items from you, and both types of items depend on the type of shop. A shop with no shopkeeper is considered abandoned.

Generation

Shops have a base 3/DL chance of being created on any dungeon level between level 2 and Medusa's Island, with the exception of the Oracle level. The creation of a shop assumes there is a suitable room to put them in (i.e., no stairs, only one door) and that there are enough rooms on the level to start with - the minimum number of rooms required is 3 for normal dungeon levels, and 4 for a branch level. Note that this means that there will always be a shop on each of levels 2 and 3 if the conditions are right (which in practice turns out to only be the case about 45% of the time).

With the exception of bones and Orcus-town, shops are never generated abandoned, and are never restocked under any circumstances - the only way they can gain more items is if they are brought in by you, a dead player from a bones file, or very rarely another monster.

Table of shops

The probability of a given type of shop being generated is detailed in this table:

Shop Probability Stock
general 42% 100% random
used armor dealership 14% 90% armor, 10% weapons
second-hand bookstore 10% 90% scrolls, 10% spellbooks
liquor emporium 10% 100% potions
antique weapons outlet 5% 90% weapons, 10% armor
delicatessen 5% 83% food, 5% fruit juice, 5% water, 4% booze, 3% ice boxes (containing corpses)
jewelers 3% 85% rings, 10% gems, 5% amulets
quality apparel and accessories 3% 90% wands, 5% leather gloves, 5% elven cloaks
hardware 3% 100% tools (containers may contain random items that are also for sale)
rare books 3% 90% spellbooks, 10% scrolls
health food 2% 70% vegetarian food, 20% fruit juice, 4% healing, 3% full healing, 2% scrolls of food detection, 1% royal jelly
lighting Minetown only 48% tallow candles, 30% wax candles, 9% oil lamps, 5% brass lanterns, 5% potions of oil, 3% magic lamps

Accessories and rare book shops may not be larger than 20 squares (including the non-stocked squares); if they would otherwise be (about half the time), they are converted into general stores instead.

Special levels with shops

The following special levels are guaranteed to have shops at fixed locations:

  • Minetown (except for Orcish Town) is guaranteed to have at least 1 shop, including Izchak's lighting store. In addition, the first shop generated in Minetown will always be a health food store when the player is a Monk.
  • The Tourist Quest has several guaranteed general stores: two in the locate level (The Thieves Guild Hall) and two in the goal level (The Shades).
  • Orcus-town is usually host to a few abandoned shops.

Closed shops

Shops can also be generated "closed", in which case the message "Closed for inventory" will be written in dust outside of the shop door. The shop door itself will be locked. Breaking down the door will anger the owner unless you immediately pay 400 zorkmids; opening the door with an unlocking tool, wand of opening or knock spell allows you to enter and shop as usual. Shops in special levels cannot ever generate closed.

Mimics

Main article: Mimic

Any mimics you encounter are most likely to appear in shops, disguised as items. There is a (dungeon level - 1)% chance of a mimic generating on a given shop square instead of an item.

Traps

Traps cannot normally be generated in shops, with the exceptions of shops placed on special levels. In practice, this will most likely occur in the Tourist quest and Orcus-town - while the various layouts of Minetown contain two traps each, they are very rarely placed within any of the shops.

The shopkeeper

Main article: Shopkeeper

The shopkeeper is a human monster that owns the shop and its contents and buys and sells items within. They are responsible for the upkeep of the shop as well - this includes magically repairing most damage done to the shop's floors, walls and door, and removing most traps that are set within their shop(with the exception of pits or webs), including those made by you. Damaged walls, broken doors and holes are repaired in five turns.[1][2] If the shopkeeper should end up dead for any reason, or else a shop has no shopkeeper, then the shop's items are free for you or any monster to take.

The following information pertains to an upcoming version (NetHack 3.7.0). If this version is now released, please verify that it is still accurate, then update the page to incorporate this information.

Shopkeepers will now remove pits and webs as well.

Theft prevention

Main article: Stealing from shops

Shopkeepers are 50% faster than a normal character's base speed, and will keep close to their shop's entrance - this makes it difficult, but not impossible, to walk out with unpaid items. See the article linked at the top of this section for more information on how to steal from shops, and see the article on shopkeepers for more details about their movement.

Barring the entrance

In addition, shopkeepers will block the entrance square (the square inside the shop that is directly in front of the door) and will not allow you to enter their shop if you are invisible, have a visible pick-axe or dwarvish mattock, and/or are currently riding on a steed. If you dismount, become visible, or remove the digging tool(s) from your open inventory (including placing it in a container), you will be allowed entry. Note that the door of the shop is not considered suitable for dropping your digging tools - this is to prevent characters with extra speed from entering on a free turn. Shopkeepers will also catch any tools you attempt to throw in.

While in a shop, the shopkeeper will prevent you from leaving if you are mounted and/or invisible.

Pick-axes

On top of the above, the shopkeeper will yell at you if you pull out a digging tool(s) from a container while inside - but this does not anger them, and you can safely sell or otherwise walk around with the tool(s) as long as you do not dig through the shop walls. Digging a pit will have them warn you about falling through holes, though this will also not anger the shopkeeper - but if you dig again and create a hole, items on the same square and possibly adjacent squares will fall through.

Attempting to enter a shop with a dwarvish mattock or pulling one out inside a shop will also identify it.

Angering the shopkeeper

The shopkeeper will become angry if you attack them, damage the shop or its inventory, or they see you leave with unpaid items or debt - additionally, if you try to leave the shop with unpaid items via a hole made within the shop's boundaries, the shopkeeper will try to grab your pack as you fall if they can get adjacent. Theft includes any items on the same square as a hole falling through it, as well as items from potentially adjacent squares. Damaging the shop door or walls will immediately prompt you to pay 400zm for a door and 200zm for each wall segment destroyed, and the shopkeeper will be angry if you do not pay. Damaging the shop from out of the shopkeeper's line of sight (e.g. with a wand of digging) will always anger them, with no chance to pay. Note that the damages the shopkeeper asks for are not ordinary shop debt: refusing to pay will not make them "remember" how much you owe them, and escaping without paying the recompense will not summon Keystone Kops.

Leaving a shop with unpaid items will anger the shopkeeper; the items then become yours, their value (including a price hike if the shopkeeper was already angry) is added to your debt, and Kops are summoned. It is then possible to pacify the shopkeeper by paying at least half of your debt[3]. Unless you are currently in the shop, you will need to be adjacent to the shopkeeper or throw the required gold at them. If you anger a shopkeeper without incurring a debt - e.g. by attacking them directly or damaging their walls or door - you can pay them 1000zm for a 2⁄3 chance of pacifying them.[4][5]. Stealing an item while the shopkeeper is already angry due to such an offense and then paying your debt will make the shopkeeper "forget" about your previous offenses: they will become calm and return to their shop as usual, without taking 1000zm. Pacifying a shopkeeper by paying for stolen goods will also pacify any watchmen on that floor and cause any Keystone Kops present to disappear.

Note that "ordinary" shop transactions are handled before any attempt to pacify the shopkeeper: if you are in a shop with an angry shopkeeper while holding an unpaid item or owing them for a destroyed item, trying to pay them will first prompt you to buy that item, using up a turn. For a low-level character facing an angry shopkeeper, that one-turn delay can be fatal, even if they otherwise have enough gold.

Hot pursuit

Unlike other monsters, shopkeepers actually have two distinct "angry" states: they can be rendered hostile like any other monster, but they can also be put into a state referred to internally as "hot pursuit", which is tracked separately from standard hostility.[6] A shopkeeper who is merely angry will attack you if you are inside their shop, but will not leave the shop to pursue you, though they will still use any ranged attacks and block you from re-entering their shop. A shopkeeper in "hot pursuit" will chase you across the level; if they lose sight of you, they will wander like any other monster, rather than returning to their shop.

Shopkeepers who are robbed are angered and put into hot pursuit, as are those whose shop walls are damaged and those who are attacked from outside their shop. The most common way of angering a shopkeeper without causing them to pursue you is to attack them from inside their shop, and then escape without stealing anything; other more obscure methods include applying a drum of earthquake. It is possible for a shopkeeper to be in hot pursuit without being angry: this requires you to pacify an angry shopkeeper in "hot pursuit" with a magic harp specifically (since other methods of pacification remove the hot pursuit status).[7] In this state, the shopkeeper will follow you and periodically ask you to pay, with a 1⁄10 chance of becoming angry again each time they ask.[8] If the shopkeeper was pursuing you because you attacked them or damaged their shop, it is impossible to pay them due to a lack of debt, and they will eventually become angry again if you stay near them.

Transactions and inventory

A shop's inventory consists of all the items on any square of its floor, with the notable exception of the "entrance square" in front of the door; this is not to be confused with the shopkeeper's personal inventory. Items belonging to the shop will have their price displayed as you move over them, and an item's price can be also viewed by near looking on their square. For containers generated as belonging to a shop, the contents are also that shop's property, regardless of whether that shop would sell them normally. You cannot buy from shops normally while blind unless you have telepathy, as you will be unable to see the shopkeeper, although you can still sell items as normal.

Pressing $ will display any credit you have, along with any debts you currently owe the shopkeeper. You can #chat to get the price of an item(s) on your square without picking anything up. Buying and selling non-magical weapons and armor will have the shopkeeper partially identify that item(s) to you - e.g., if you sell a crude dagger, the shopkeeper will reveal that it was an orcish dagger. After each transaction, they will also tell you the item's appearance if you are blind.

Buying items

Picking up items off the shop floor adds them to your inventory, with each item(s) being given an "unpaid" tag that lists their price - pressing I and then u will display all the unpaid items you are currently carrying.

You can pay for your goods by pressing p, which will prompt you about itemized billing; answering "no" to this will pay for all the items at once if possible. For itemized billing, you can pay individually for each unpaid object (or stack of objects). Items that you pay for are yours, and the required gold will transfer to the shopkeeper's personal inventory. In both cases, if you have credit at that shop, it will be used up first before any gold is transferred.

Selling

If you drop an item onto the shop floor (with the exception of the entrance square), the shopkeeper will offer to buy it if they normally carry that type of wares. If you refuse, or if the shopkeeper makes no offer, then you continue to own the item and can pick it up again without paying.

Any items that unintentionally fall onto the shop floor, e.g. from throwing them or losing your grip on them will be considered "relinquished" and automatically sold if it is a type normally sold by the shop. Any items dropped by monsters killed within a shop also becomes that shop's property - this includes you, if you die while inside a shop.

Credit

Main article: Credit cloning

If you drop any gold onto the shop floor, the shopkeeper will give you credit which you can use to buy items and pay off debts. If you sell an item to a shopkeeper that is completely out of gold, they will instead offer you store credit in exchange for the item at 90% of the normal price. Any credit given in a shop is only good for that specific shop - if you leave a shop with unpaid items in your inventory (e.g., your intrinsic teleportitis suddenly kicks in), all of your credit will be used to cover the losses, and if your credit was not enough, the shopkeeper will become angry.

You can abuse this credit system through credit cloning - see the linked article at the top of this section for more detailed information.

Usage fees

Main article: Usage fee

If you use an unpaid item with charges in a shop before paying for it and the shopkeeper is present, you will be charged a usage fee.[9] Broken or destroyed items, including the locks of chests and large boxes, also incur fees.

Pricing

Main article: Price identification

Base price

Each item in NetHack has a base price, which is modified in various ways to produce the final selling price; an artifact has its own usually-high base price distinct from its base item. Positively-enchanted weapons and armor have an additional 10 zm added to their base price for every point of enchantment.

Some items are considered "worthless"; you cannot sell them, but their buying price is calculated as though they had a base price of 5 zm:

Unidentified gems

Valuable gems and worthless glass which aren't formally identified have their base prices determined by a different mechanism:

  • When buying, the base price is that of an arbitrary valuable gem.
  • When selling, the base price is between 3 and 8 zm.

The random modifiers to unidentified item prices listed below don't apply in this case. Even if you know for a fact that a gem is valuable (by e.g. engrave-testing) and have named it correctly, you can't get its full selling price unless you formally identify it.

Gray stones don't use this mechanism; an unidentified gray stone is priced the same as an identified one.

Buying

When you buy an item, you are charged the base price, modified as follows. All multipliers are applied in sequence:

  • Your charisma grants a modifier to the buying price.[10]
  • Some characters are considered "suckers", and will be charged 1⁄3 more. You are a sucker if:[11]
  • A hostile shopkeeper will charge 1⁄3 more.[12]
  • When buying unidentified objects, in 1⁄4 of cases the shopkeeper will charge 1⁄3 more. This surcharge is tied to the individual item or stack; merged stacks will inherit the higher of the two prices, while split stacks will inherit the price of the original stack.
  • Depending on your hunger status, shopkeepers will charge more for food and comestibles:[13]
    • If you are hungry, the price is doubled.
    • If you are weak from hunger, the price is tripled.
    • If you are fainting from hunger, the price is quadrupled.
  • Artifacts are bought for four times their already-inflated base cost.[14]

Selling

When you sell an item, you are normally offered 1⁄2 the base price; charisma modifiers do not apply. If you're a sucker, as above, you are offered 1⁄3 the base price instead.

  • 1⁄4 of shopkeepers will pay 1⁄4 less for unidentified objects; this modifier is consistent for a given shopkeeper.
  • Artifacts are sold for 1⁄4 of their base cost.[15]
  • If the shopkeeper has gold, but not enough to pay the sale price, they will offer as much gold as they have, with the message "<shopkeeper> offers only <amount> for your <item>".
  • If the shopkeeper has no gold at all, they will offer store credit equal to 90% of the sale price, as above.

Strategy

For shopkeeper-specific strategy, see Shopkeeper#Strategy.

Shops are a very useful resource overall, particularly in the early and mid-game - they are usually a primary source of items and equipment, and additionally provide a means of identifying them via prices, as mentioned above. They can also serve as a place to offload anything you consider junk, and can serve various other purposes besides.

It may sometimes be worthwhile to drop your gold and use credit to buy things, rather than paying directly - even if you do not plan on shoplifting, you may benefit from tricking a monster into bringing the gold back to you. Covertly stealing expensive items (usually including artifacts) may also be worthwhile for the early advantage they provide, e.g. a powerful weapon, or something to sell back to the shopkeeper for a significant price.

Shopping while invisible

If you are invisible and either do not want to wait until you are visible again, or your invisibility cannot be undone (either due to a cursed source or a quaffed blessed potion), then you can use one of the following methods to safely enter or exit a shop as normal:

  • Wearing a non-cursed mummy wrapping is the safest and most typical method, as it works in a mass majority of cases with the exception of a cursed cloak.
  • Teleporting into and out of the shop is possible, but requires teleport control for you to enter reliably.
  • Jump diagonally through the door.
  • Hurtle diagonally through the door by throwing things while levitating due to Newton’s Third Law.
  • Dig down on the level above - but this leaves you completely at the mercy of RNG.
    • You can also dig a hole out of the shop through the floor - this is safe as long as no unpaid items fall through with you.
  • You can forego entering entirely and instead use a pet and a magic whistle to steal from the shop.
  • Use any holes in the wall dug by a tunneling monster (e.g., a dwarf with a pick-axe or mattock); each hole will be magically repaired in at least 5 turns after it was made if no monster is present on that square.
  • Polymorph into a xorn to phase through the wall.
  • Be very fast (e.g. usually from wearing speed boots) and beat the shopkeeper to the door. Note that the shopkeeper will move to stay ahead of a player's intrinsic speed - this does not account for speed from polyself.

These methods are less safe and/or may cost you some gold:

  • Carry 800zm or more, then polymorph into an umber hulk or rock mole and chew through the wall, and pay for the damage.
  • Carry 800zm or more, then destroy the closed shop door, pay for the damage immediately, then enter/leave. The door will be fixed afterward.
  • Teleport the shopkeeper - but this will anger them, and you will have to avoid the shopkeeper on the way out unless you can pacify them.
  • Kill the shopkeeper, directly or otherwise - doing so directly counts as murder, and you are deprived of price identification for that shop in either case.

Shopping smart and safe

While each character's shopping needs will differ, price identification can generally narrow down what wares you may want to focus on, and even without thorough memorization a player can get an idea of which items are valuable.

There are other multipurpose pointers for a shopper to keep in mind - in general, never buy or sell gems that are unidentified.

In general, it is a Bad Idea to randomly wear or use items within a shop, since even if your pet is not averse to moving over them, you may end up endangering yourself or complicating play as you would with any randomly use-tested item - you may end up quaffing a potion of paralysis, wearing a helm of opposite alignment, exploding a cursed wand, or end up reading a non-cursed scroll of fire with the shopkeeper nearby and/or unpaid flammables in your inventory.

One particular obstacle to this end is the scroll of scare monster - a scroll that is cursed or has been picked up and dropped once turns to dust when picked up, which incurs a charge for the destroyed item. Novice adventurers who shop by picking up items can find themselves trapped in a store with no money and no way out. There is also the more direct threat to your life posed by mimics of any kind - even small mimics can end an unwary early character, and particularly unfortunate sorts may end up stuck to a giant mimic.

There are several ways to prevent any mishaps while shopping:

  • Be sure #chat to a shopkeeper before picking up certain items directly.
  • Always carry a few hundred spare zorkmids to cover any accidental charges you incur. In a worst-case scenario where you cannot avoid incurring damages, you may need to sell some additional items in your inventory - depending on your situation, this may be preferable to being branded a thief or dying.
  • Before entering a shop, quaff a non-cursed potion of object detection. You may notice suspicious blank squares if you have not yet seen the contents of the shop - those are likely to be mimics.
  • "Obvious" out-of-place objects are often mimics, especially in specialized shops (e.g., a long sword in a potion shop, or down staircase in any shop). However, this does not work as well for general stores (which sell almost anything) and bones files (which may have the inventory of the dead player - although you may encounter signs of this beforehand).
  • If you are playing with default tiles or standard ASCII, you can also discern mimics by their glyphs - they will appear as "strange objects", and the tiles for strange objects are chests with eyes peering out of them (Strange object.png/] versus Chest.png/(). Additionally, their glyph is usually the mirror of the glyph for armor ([) - the only time ] is used for anything else is for actual armor on the Rogue level.
  • Telepathy and warning will reveal mimics and/or their locations.
  • The ring of protection from shape changers will force mimics into their standard form.
  • Any form of monster detection can reveal mimics - note that a non-blessed potion of monster detection or a detect monsters spell cast at lower than Skilled level only reveals their current location, while detection from a blessed potion or Skilled (or better) spell passively remains active.
  • A safe and surefire way to uncloak mimics inside a shop is to throw a single gold piece across each row of the store - this does not use up valuable projectiles and will only establish credit. Be careful not to hit and possibly anger the shopkeeper!
  • Search before walking onto an item to uncover any mimics - this will prevent you bumping into them, as the larger ones are sticky.
  • A stethoscope can also uncover mimics, and the first application of a stethoscope per turn is a free action.
  • Healing a mimic disguised as an item (e.g. via a spell of healing) will indirectly expose it, with the "object" seeming a more vivid color than before.[16]
  • If you lack any means of detection and are risk-averse, only walk where your pet or the shopkeeper has walked.

Combat

A shop can also function as a refuge if you need to heal or fight a powerful enemy. You can pick up an item and stand so that the shopkeeper blocks the door, preventing non-phasing monsters from getting in. If you stand a knight's jump from the door, you will not be exposed to ranged attacks from outside as well. You can then move next to the door to fight, and step away to heal at your leisure.

Zen shopping

Main article: Zen

For zen players, shops are one of the few methods available to identify item the appearances, particularly scrolls and potions. However, being unable to see the shopkeeper poses a great danger: paying only works if you can see the shopkeeper, and failing to discern the shopkeeper's location by searching before safe-moving via m will nearly always result in death. It may be advisable to avoid shops altogether until you have telepathy.

Braver and/or more experienced players can bring a container to place items in (ideally a bag) and a pet to steal the container back in order to speed up the process of re-acquiring sold items that the shopkeeper has identified. It is also possible to drop enough gold to cover your purchases and then teleport, jump or phase out after picking up your desired items, even without teleport control - unfortunately, this is not nearly as reliable early in the game, and most zen players acquire telepathy before any of these other methods become available. Selling items works as normal, and might be useful if you get burdened before acquiring telepathy.

History

Shops have been present in the game's code since the original release of Jay Fenlason's Hack, and make a proper first appearance in Hack 1.21, a variant of this first Hack. Hack 1.21 also included a shop at the beginning of the game, where characters purchased their starting items, rather than bringing their initial inventory with them into the dungeon.

Izchak and his lighting shop in Minetown were introduced in NetHack 3.2.0 as part of a tribute to late DevTeam member Izchak Miller.

In default installations of NetHack 3.4.3 and earlier versions, along with some variants based on those versions, prices are not displayed by default, and you must pick up items or #chat while standing on them to learn their price. Additionally, modifiers for unidentified items applied to identified items as well, and the lower price for sold items was applied per-sale - by repeatedly dropping an item, refusing the shopkeeper's offer, and picking it up again, you would eventually get two different quotes. A bug was also present in those versions that could prevent you from leaving a 2x2 size shop through normal means; saving and reloading the game while standing next to the shopkeeper may alleviate this bug in a semi-sane and perfectly legal fashion.

The health food store was introduced in NetHack 3.6.0. Beginning in 3.6.1, autopickup no longer picks up unpaid items - this prevents any mishaps involving a cursed scroll of scare monster.

Messages

You hear someone cursing shoplifters.
You hear the chime of a cash register.
There is a shop on the level.
You hear Neiman and Marcus arguing!
As above, but you are hallucinating.
This shop appears to be deserted.
There is no shopkeeper in the shop.

Variants

Some variants may feature entirely different types of shops, in addition to adding more locations and/or functions.

A user has suggested improving this page or section as follows:

"Cover the rest of the variants eventually."

SLASH'EM

SLASH'EM adds pet stores, randomly generated light stores, tin shops, and music shops. SLASH'EM also has the black market, a special floor-wide shop with its own branch tended to by One-eyed Sam and his assistants. Shopkeepers are also much more powerful than in vanilla NetHack.

Shops can be additionally found in more locations as well - the Mall is a special level that contains several shops and can appear early in the dungeon.

UnNetHack

UnNetHack also contains pet stores, randomly generated light stores, tin shops, and music shops. The Town branch is a new addition that contains a few shops, including most of the newer ones.

UnNetHack also contains its own version of the black market, with the same layout as SLASH'EM - UnNetHack's One-eyed Sam is a woman, and there is a second possible map that instead splits the market into several independent shops with their own shopkeepers, while One-eyed Sam herself keeps watch.
