Rooms in the Basic Game

Common Room


The default type of room has no special symbol on the map, and this type of room makes up the majority of the map. They can have up to four adjacent rooms, which can have any type. Most of them will contain monsters 'indigenous' to the current chapter. Upon clearing such a room, a player might be rewarded with a random pickup or chest that will spawn in the center of the room (unless there's an obstacle like a stone, in which case it will spawn at the nearest free space to the top left).

Aside from the generic monster rooms, there are also some notable types that are still somewhat different: They are mostly void of monsters, and for example present an object like a chest, or a game of chance in the center. As with every common room, it is possible for them to exist multiple times on the same level, since technically speaking they are no special kind of room.
