Wizard

The Wizard is a Hardmode NPC that sells magic-related items. The Wizard can be acquired via open areas underground during Hardmode. He can be found at the cavern layer or lower, where he spawns rarely and appears to be bound, much like the Stylist, Goblin Tinkerer and Mechanic. Talking to him will free him, after which he will respawn as long as a vacant house is available, even if killed.

When enemies are in his vicinity, the Wizard hurls fireballs at them in a similar fashion to the Flower of Fire.

Names
The Wizard may have any of the following names:

Tips

 * The Dungeon contains a large number of open areas that may provide the most frequent opportunities for the Wizard to spawn. Until defeating Plantera, no new Hardmode enemies spawn there, making it a safe and quick place to search for him.
 * The Bound Wizard is one of the few entities that can be detected by the Lifeform Analyzer.
 * A Hunter Potion can be used to locate the Wizard.
