The Frozen Key is a Key which is a rare drop from enemies in the Snow Biome. This key will unlock a Frozen Chest in the Dungeon after the defeat of Plantera. After unlocking the Frozen Chest, you will find the Staff of the Frost Hydra inside of it. 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.
