Tim

Tim is a Mage enemy found rarely underground in the Stone Layer. He always drops the Wizard Hat and defeating him is the only way to obtain one.

Tim is similar to the Goblin Sorcerer, in that he fires a projectile 3 times before teleporting. These projectiles, called Chaos Balls, do 20 Damage each and can travel through solid blocks, though a player can destroy them with any weapon. While Tim's attack resembles that of the Goblin Sorcerer, he has double the defense and five times the health.
