Wizard

The Wizard is a Hardmode NPC that sells magic-related items. The Wizard can be acquired via open areas in a Dungeon or anywhere 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 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.

Items sold
Once the Wizard has been freed, he will sell the following:

Names
The wizard may have any of the following names:

Most of these names refer to famous wizards in popular culture: Merlin from the Matter of Britain, Michael Moorcock's Elric of Melniboné, Ningauble from the adventures of Fafhrd and the Gray Mouser, Leomund, Fizban, and Dalamar from Dungeons & Dragons settings Greyhawk and Dragonlance. The name Sargon may be a reference to Sargon, an ancient Akkadian king. Many of the rest refer to elves from the Silmarillion and The Lord of the Rings including Hirael, Maelor, Arwyn, and possibly Berwyn.
