Biome

A biome is an area of the Castleminer Z world that is environmentally distinct from the game's other biomes. There are currently 7 Biomes in the game: Starting area, floating islands, desert, mountains, snow, the descent, and hell on earth.

Purpose of biomes
Each biome has different characteristics that make it unique. Biomes that are farther from the starting area contain more valuable materials and more challenging enemies, each biome also has it's own type of dragon.
