Crimson Key Mold

The Crimson Key Mold is a rare drop from crimson enemies used to craft the Crimson Key. It can be found from any monster in the crimson biome with a 1/4000 drop rate, or a 0.025% chance.

Farming

 * A good way to farm for the key mold is to farm the Brain of Cthulhu because the Creepers Count as kills.


 * Another good way to farm for the key mold is to create an artificial Meteorite Biome and stand in honey with Turtle Armor.
