Biome Key Molds

Biome Key Molds are extremely rare Hardmode crafting materials that are used to craft Biome Keys, which open Biome Chests. After the Wall of Flesh is defeated, every enemy killed within an eligible biome has a 0.04% (1 in 2500) chance of dropping a Biome Key Mold, with the exception of meteor heads. 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, Biome Keys drop instead of Biome Key Molds, and all existing key molds will change into their respective keys.
