Confirming what Helios said. You don't have the spells per turn to spare on damage spells, which only then Destroyer would make sense. Sacrifice 2 has always sufficed for my Paladin and Warrior games.
Distortion is by far more useful. Put another point in the Healer talent if you don't know where to put your magic runes. You need some to get Tolerance and its prerequisites, too.
