Hallowed Mimic

Hallowed Mimic is a Mimic monster that spawns in the Underground Hallow or when you put a Key of Light into an empty chest in a Hardmode world (with autopause disabled). It is a stronger version of the normal Mimic with several new moves and drops unique weapons. It drops powerful items, like all mimics. Like all other mimics, it will disguise itself as a chest until attacked or if a player comes close to it, though the biome-exclusive mimics do not resemble any chest currently in the game. See the Mimic page for more info.
