Biome Configuration
A Biome is an area of the game that has a similar environmental/elemental theme. Each biome is paired with another biome that is the opposite element. The player's goal is to restore the elemental balance of the planet by defeating the bosses of each biome. The configuration of biomes when generating a world are driven by which ones are available from DLCs and which pairs to use. Beyond that, they can vary in size and how scrambled up they are. Biomes are always selected in opposing pairs, so you can't have fire without also having ice, for example.
Biome Size
The size of each biome, measured in rooms, controls how much exploring there is to do. This largely controls how many rooms are created for each part of the objective graph.
| Bits | Type | Description |
|---|---|---|
| 00 | Normal | Biomes are a reasonable size for exploration. |
| 01 | Small | Smaller than normal biomes for a faster experience. |
| 10 | Large | Larger than normal biomes for more exploration. |
| 11 | Huge | Huge biomes that are uncomfortably sprawling for those that like that sort of thing. |
Biome Cohesion
The likelihood that each biome will be split into multiple pieces.
| Bits | Type | Description |
|---|---|---|
| 00 | Monolith | Each biome is essentially one large piece. |
| 01 | Clustered | A small number of large clusters of rooms. |
| 10 | Disjoint | A large number of small clusters of rooms. |
| 11 | Chaotic | Each neighboring room could be from a different biome. |
