w/Nalia and Anomen ONLY, at level 11 and 10, used magic resistance then lower resist (have to do it in that order) to nerf his mag.res. to almost zero, cloudkill, holy smite, fireball and ice storm to finally wax that giant pet to ground. I have his hide, crom fayer scroll, gems and some spells plus 45,000 xp 4 my party.
(Spoiler) He is NO LONGER sumthin that I even FEAR!!! I might even try that on the red dragon, get the avenger for sale, no paladins in my party, and take his hide and give Mazzy/Anomen the armor made out of it, and sweet revenge for tricking me!! HAHAHAHAHA!!!
Maybe NOT fireball, hust more smites and possibly insect plagues...any idea on how to whack that oversized pest w/out even meleeing him???

Yeah, I can't believe I hid fom him the first 2 times I went through the game.
