Either I've gotton much better at utilizing characters, or the Shadow Dragon was on Prozak.
The other two times that I have beaten him, were either an all out battle with at least two people dying, or cheesy tactics with the wand of Cloudkill.
This time however, it was just me (Berserker,9/Mage13) and Jaheira. I had Jaheira in the corner casting any and all sorts of animal summoning (for fodder, I don't think that any of them actually did any damage to him), and myself casting two Lower Resistances followed by 4 Skull Traps and a couple blasts from the Wand of Lightning.
And down he fell without us taking one point of damage!
I almost wish I had just went with a straight mage or Sorcerer, but that Enrage is just to useful for warding off Stun, Confusion, etc.

Congratulations!!!!!!!! that is a BG2 moment!!!
