Illusionist's Attire is the Zandalar Tribe set for mages.

Most Illusionist's Attire items can be acquired through quests given by Al'tabim the All-Seeing, who can be found on the Yojamba Isle in Stranglethorn Vale.

The exception is Hazza'rah's Charm of Magic, which is formed by combining a Punctured Voodoo Doll (mage) with Gri'lek's Blood, Renataki's Tooth, Wushoolay's Mane, and Hazza'rah's Dream Thread.
