Mage Hat

Defeat the Throbbing King with a Mage cat to unlock the Mage Hat, a cosmetic head armor piece. The Mage's AoE spells like Fireball and Blizzard are perfect for clearing Clot spawns during Phase 1, and damage-over-time effects like Poison synergize well with the extended duration of that phase. Keep maximum distance from the King and use Frost Blast to freeze enemies in place. In Phase 2, Chain Lightning and Meteor Storm can punish the King even as he jumps around. Pair with a Tank to absorb hits, since the Mage's low CON and STR make it a prime target.
