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 that drops unique weapons themed after the Hallow. 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.

Hallowed Mimics attack by jumping towards the player, like other mimics; however, they also have the ability to shut themselves, during which time projectiles will be reflected back towards the shooter. They can also perform a pound-like attack in which the Mimic leaps over the player's head and swiftly drops down.
