Key of Light

The Key of Light is a craftable item which spawns a Hallowed Mimic when placed in any slot of any empty Chest. The world must be in Hardmode and the only item inside the Chest must be a single Key of Light.

The Hallowed Mimic is spawned as soon as the Chest is closed, consuming both the Key of Light and the Chest.
