Rune Wizard

The Rune Wizard is a rare Hardmode caster-type enemy that is found in the lower Cavern layer. Upon spawning, he will proceed to fire magical projectiles at the player that penetrate terrain, similar to the Fire Imp's Burning Spheres. However, unlike Burning Spheres, the Rune Wizard's projectiles cannot be destroyed with weapons. The Rune Wizard will teleport to a new location after firing 8 projectiles in random intervals. He will always drop the Rune Hat and Rune Robe upon death.

Tips

 * An easy way to fight the Rune Wizard is to continually attack him. This will essentially paralyze him, preventing his attacks and teleportation. Lighting him on fire can be a very effective way to fight him.
 * Due to the extreme contact damage, it is easiest to fight the Rune Wizard using ranged weapons. However, due to the narrow caves where he spawns, this can be difficult.
 * The Piranha Gun is very effective against the Rune Wizard, given that the player manages to hit the enemy, since it follows teleports.
 * The Megashark is extremely effective at keeping the Rune Wizard paralyzed due to its high rate of fire.
 * Minions and sentries, provided they assail the Rune Wizard, can prove to be a great way to combat the enemy due to their ability to effectively paralyze the enemy.

Trivia

 * The Rune Wizard can be considered the Hardmode version of Tim. The vanity items dropped closely resemble the same items dropped by Tim. The two also have similar spawn depths, attack patterns and drop unique items only obtainable by defeating them. Also, according to the Bestiary, the Rune Wizard is Tim's older brother.
 * Due to the Rune Wizard's extremely low spawn rates and its spawn location requirements, it can easily be considered the rarest enemy in the game.
