Biome Key Molds

Biome Key Molds are extremely rare Hardmode crafting materials exclusive to the console and mobile versions used to craft Biome Keys, which open Biome Chests. After the Wall of Flesh is defeated, every enemy has a 0.04% (1 in 2500) chance of dropping a Biome Key Mold. The type of Biome Key Mold that is dropped depends on the biome you are currently in (Jungle, Corruption, Crimson, Hallow or Snow).

On the PC version, Biome Keys will drop instead of Biome Key Molds, and all existing key molds will change into their respective keys.
