Dungeons are procedurally generated structures that usually consist of multiple rooms connected by paths, sometimes incorporating scenes.

The game uses its dungeon system to generate structures that players would not traditionally consider dungeons, such as sub-biomes and small houses.

Every dungeon in the game is listed below. Note that not all dungeons have official names.

Random dungeons

The following dungeons generate in the world randomly. Dungeons always generate before scenes; scenes without a set distance cannot spawn in chunks occupied by dungeons.

Weight determines how likely a dungeon is to generate relative to other dungeons in the same section.
