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 Rune Blast 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 in any way. He will teleport to a new location after firing six projectiles, and 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. Inflicting debuffs like On Fire! can be a very effective way to fight him.
 * Viable weapons for paralyzing the Rune Wizard include the Piranha Gun, weapons with a high rate of fire, like the Megashark, as well as most summoning weapons.
 * Despite making no attempt to touch players as part of his attacks, the Rune Wizard inflicts extreme contact damage, enough to kill most players in around 3 hits. His projectiles deal far less damage, but he can nonetheless be very dangerous to players with weak Hardmode items, especially if he spawns in an unreachable place.
 * In, the contact damage is often enough to instantly kill the player.
 * Due to the extreme contact damage, it is advisable to fight the Rune Wizard using long-range weapons. This may prove difficult due to the narrow caves where he spawns, however.

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 be considered one of the rarest enemies in the game.
 * The Rune Wizard inflicts the second most contact damage of all enemies, and the fourth most damage in the game. His contact damage is as much damage as the Pirate Captain's cannonballs, Skeleton Sniper's sniper bullets and Clown's bombs, fourth to the Martian Saucer's death ray (berserk), the Dungeon Guardian, and the if fought during day.
