Werewolf

The Werewolf is a hardmode enemy that spawns only during a full moon. In this time they become as common as Zombies, so be aware that you may get swarmed.

When a Werewolf attacks, it has a chance to give the Bleeding debuff. At close range, it will attack the player by leaping or lunging at them, closing distances quickly to catch unwary players off-guard.

You can transform into one by wearing the Moon Charm.
