It was not easy, I did a lot of running around. Finally, I backed myself into a corner and let her approach and withdraw, back and forth. She seems to have, not exactly set, but somewhat of a pattern. While she was doing this I was able to wear her down. Only every once in a while would she attack. In the meantime, her minions didn't come around, although I could still hear them, which helped a lot as I didn't have to cope with them.
Actually, I got the first three, but I was getting very low on health potions, and just wanted to get out of there.
I'm in Fathien's Tomb, got the two levers, and am trying to find the armor.
