For tips on obtaining Key Molds, see Guide:Farming Biome Keys or 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 1/2500 (0.04%) 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  Desktop,  Console, and  Mobile versions, Biome Keys drop instead of Key Molds, and all existing Key Molds will change into their respective Keys if any exist in the world.

Notes

• Key molds can also be dropped by bosses, like any other enemy, if the player is in the right biome.
• Enemies in artificially created Corruption and Crimson biomes will still drop appropriate key molds, even if the world does not have a corresponding Biome Chest.
• Because of how many slimes it spawns during the battle, the King Slime is an efficient way to get biome key molds.

Trivia

• Unlike some real-world molds, these are consumed in the crafting process and cannot be reused.
• Although the key molds were removed in 1.3.0.1(Desktop, Console and Mobile versions), their sprites still exist within the game files of the  Desktop version.
• Since it was added after the removal of Key Molds, the Desert Key(Desktop, Console and Mobile versions) does not have a corresponding mold.
