I just used 7 scrolls of life-half of a healing stone and still had to abort the spellplague master quest. I was there for over an hour so it was a complete waste of time. Kabar is defeated but he keeps coming back over and over. There was only two people left when I quit, the other 3 or 4 had left. I don't appreciate using my healers, scrolls mega potions for what turns into a pointless quest. I have way over the stats supposedly needed. This is so not cool.
