Rune Wizard

The Rune Wizard is a rare, Hardmode Caster Enemy that is found underground after entering Hardmode. Upon spawning it will proceed to fire magical projectiles at the player that penetrate terrain, similar to that of the Fire Imp's. However, unlike the Fire Imps projectiles, the Rune Wizards cannot be deflected with weapons. Rune Wizards will teleport to a new location after firing 8 projectiles in random intervals, or after receiving damage. It will always drop the Rune Hat and Rune Robe upon death.

Tips

 * The Rune Wizard inflicts extreme contact damage, enough to kill most players in 2 hits. However, its spells do far less damage, at around 50 with endgame gear.
 * The Rune Wizard will appear more often around underground gem caverns.
 * An easy way to fight this foe is to continually attack him. This will essentially paralyze him, preventing his attacks and teleportation.
