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 Imp's projectiles, the Rune Wizard's 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 3 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.
 * Rune Wizards inflict the second most contact damage of all enemies, second only to the Dungeon Guardian, but as it doesn't attempt to touch players, this isn't terribly important.
 * It is recommended to try to dodge his projectiles as much as possible and attack with ranged. This is not so easy to do since he will only spawn in caves, meaning closed and roughly small areas.
 * The Piranha Gun is very effective against the Rune Wizard since the piranha follows teleports.
