Apparently, the Sorcerer's Volatile Familiar from Daedric Summoning skill line explodes not only on death (wich it should, considering the tooltip) doing % damage based on max magika, but also on re-spawn. So you can spam Volatile Familiar and do 400-500 AOE dmg until out of mana while being at a reasonable distance.
¯\_(ツ)_/¯
