The Crimson Key is a Biome Key that the player can obtain from any enemies that spawn in the Crimson biome. This key will unlock a Crimson Chest in the Dungeon, after Plantera has been defeated.
- Because Mobile & Console-Version aren't in v1.3 yet, they still have to craft the Key using: 1 Temple Key, 1 Crimson Key Mold, 5 Souls of Fright, 5 Souls of Might and 5 Souls of Sight.
- See: Farming Guide
- Now drops in place of the Crimson Key Mold.
- Added to the game.
