Step Biome

Step Biome is a biome that can replace the Jungle once Golem is defeated. It features no mobs, but better loot, and others. To counteract this, it is filled to the brim with hazards (especially bottomless pits). It's theme is similar to that of a disco party. It also has a relatively easy boss.

Biome Difficulty: Very Hard (6 coins)
