Biome Key Molds

Biome Key Molds are extremely rare Hardmode crafting materials that are used to craft Biome Keys, which open Biome Chests once Plantera is defeated. 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 and statue-spawned enemies. The type of key mold that is dropped depends on the biome the player is currently in (Jungle, Corruption, Crimson, Hallow, or Snow).

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

Trivia
