I might as well drop the Hawkmail. Right now she's lv.33 so she can only use flawless diamonds right now. I am using PlugY, and when I cube gems they are left in the shared stash if anyone needs them.
My frenzy barb (35) and flame artsin (34) got through without much trouble. Perhaps I have to rethink this build a bit.
EDIT: I had to take a few Healing potions but with Tancred's, 3/3 Nagelring and a Venom Ward (10 MDR) I was able to bring down Duriel. It didn't matter that my Lightning res dropped from 75 to 61, as Duriel doesn't use lightning.
btw: I stood against the wall as you told me
that did the trick.. I was a fool running around earlier
