Well, the Prime 3 spell Celestial Fire can do aggravated damage at Prime 5. In theory, any arcanum can do aggravated at mastery, but it always costs a point of mana to do so. Ultimately, in my opinion, you've picked a good arcanum to master, since prime has direct damage, magic item creation, illusions, and a master of prime basically never needs to worry about mana acquisition.
