Random vault (UnNetHack)
Jump to navigation
Jump to search
Random vaults are a part of the level generation formula introduced in UnNetHack. The name is a misnomer: these are entirely unrelated to the hidden vaults filled with gold, and connect normally to the rest of the dungeon.
Every room that isn't part of a special level and not a vault is selected from the list of random vaults.
The "normal random room" has a 40/41 chance of being selected. All the others have a 1/2050 chance of being selected.
Some random vaults, including the "normal random room", can be further transformed into Special rooms.
In the UnNetHack source code, the random vaults are defined in dat/vaults.des
.
