Another vote for Cryomancy (you put aeromancy on there but not cryo? For shame).I could freeze the insides of someone, shoot an ice spike at the face, or if I wanted the nonlethal approach, I could freeze the hands or feet of someone.
Also could be used to fly, depending on level of control over ice. I could just create a platform of ice and control it while I stand on it.
