Wow, I was not expecting that. As a child I was famous for watching Aladdin, turning to my parents as the credits rolled, and saying, "Again". When I think of Jafar I think of control, so maybe some charm spells, crowd control, and if you're going for evil sorcerer, no-nonsense, big damage spells? That's what I get from Jafar as a touchstone, anyway. Thanks very much for personally responding!
More thematic feel than specific abilities. It's really hard to say a character like that and not start to link to what that character can do.
