I'm finding that my frost weapon is quite handy, I suppose that's a sorta-stun. That, along with poisoned weapon and poisoned skin makes for a nice frosty green ice sculpture. Add the hell spikes to that and I'm doing much much better this time around with a rogue than with the mage last time. (Wimps!! No hps at all.) I left one point in warrior add fire/lightning/poison damage. In the end game last time I drank many super elixirs and my resistances were all around 1000. I don't know if that necessarily helped, but it sure didn't hurt (and I was afraid).
What exactly (or generally) is Spiritual Damage?
