The Corruption Key is a key that the player can obtain in Hard Mode as a drop from creatures in The Corruption. This key will unlock a Corruption Chest in the Dungeon after the defeat of Plantera. Before defeating Plantera in a world, like all other biome keys, the tooltip will say "It has been cursed by a powerful Jungle creature", and is unable to be used.
