Crimson Chest

The Crimson Chest is found in the Dungeon after hard mode is enabled. It has a 100% chance to contain the Vampire Knives, which arguably is the best meele weapon in the game. The chest is opened with a Crimson Key which is dropped from a random Crimson enemy in the Crimson when hard mode is enabled. The Crimson has a chance to replace the Corruption when generating a new world.
