Mages of Strixhaven

From publisher blurb: Become a student of magic in this installment of Unearthed Arcana! This playtest document presents five subclasses for Dungeons & Dragons. Each of these subclasses allows you to play a mage associated with one of the five colleges of Strixhaven, a university of magic. These subclasses are special, with each one being available to more than one class.
