My problem with Deific Wrath is that you can use it all day long, whereas similarly powered moves by a sorcerer are limited by your number of appropriate spell slots. Also, it's a little unclear whether you get to target one creature per level or whether you deal 1d8 per level the way it's currently worded. I assumed the latter (and that seems to be what you meant based on the feats), which is pretty strong, especially when you add appropriate feats to it. I mean, I'd play this class solely for that ability - I come from a low-op background, you see, playing non-mailman style blaster casters.
