Special rooms, shops and level sounds in NetHack 3.3

by Dylan O'Donnell

This spoiler only considers the special rooms that can be generated randomly in the main Dungeons of Doom. Certain special levels have their own predefined special rooms (shops in Minetown and the Tourist Quest, zoos in Sokoban and the Wizard's Tower, and many others).


Special rooms

The usual name describing the room is given first, then in brackets the chance of creation, the range of Dungeon Levels within the Dungeons of Doom in which the room is eligible to be created, and any other constraints on generation. Following this is a list of messages (level sounds) which may be given when on a level which has that room, and messages given when entering the room (as opposed to greetings from its occupant, if any).

The chances listed are cumulative; once one type of special room has been created, no others are eligible to be created, and they are considered in order. No special rooms from this list will be created on the Oracle, Big Room, Rogue, Medusa or Castle levels.

Shop (3/DL, DL 2+, not below Medusa)

Throne room (1/6, DL 5+)

Leprechaun hall (1/8, DL 6+, leprechauns not genocided/extinct)

Zoo (1/7, DL 7+)

Temple (1/5, DL 9+)

Beehive (1/5, DL 10+, killer bees not genocided/extinct)

Graveyard (1/6, DL 12+)

Anthole (1/8, DL 13+)

Barracks (1/4, DL 15+, soldiers not genocided/extinct)

Swamp (1/6, DL 16+)

Cockatrice nest (1/8, DL 17+, cockatrices not genocided/extinct)

Vault (independent 50% chance)

Miscellaneous level sounds

Shops

Shops have a base 3/DL chance of being created between level 2 and Medusa, provided there is a suitable room to put them in (no stairs/portal, 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 both levels 2 and 3 if the conditions are right (though the entrance to the Gnomish Mines often means that there's more stairs to get in the way.)

There are eleven types of shop; of these, one (lighting) can only appear in Minetown. Their probabilities of random creation and their stock distribution are:

Name Prob Stock
general 44% 100% random
used armor dealership 14 90% armour, 10% weapons
second-hand bookstore 10 90% scrolls, 10% spell books
liquor emporium 10 100% potions
antique weapons outlet 5 90% weapons, 10% armour
delicatessen 5 83% food, 5% fruit juice, 5% water, 4% booze, 3% ice box
jewelers 3 85% rings, 10% gems, 5% amulets
quality apparel and accessories *3 90% wands, 5% leather gloves, 5% elven cloak
hardware store 3 100% tools
rare books *3 90% spell books, 10% scrolls
lighting store 0 40% tallow candle, 32% wax candle, 10% oil lamp, 5% brass lantern, 3% magic lamp

Prob is the percentage chance of a random shop being of this type. Shops with probabilities marked * may not be larger than 20 squares; if they would otherwise be, they are converted into general stores instead.
