Sadly, we haven't seen an outfit for the Wizard yet, we just know it's there. Basically, you can pick a type of attack, then you can pick an element to go with it, making it that much more powerful, and it costs a lot of BP. For example, you can pick "Arrow" as a type of attack, then pick "Lightning" as an element, to make "Lightning Arrow", we see Magnolia use this skill in the special movie!
