You should have marked your post with a spoiler tag, Freke, since you're revealing the identity of a major villain in HoW. Please remember for next time. [img]smile.gif[/img]
It's difficult to avoid her initial breath weapon since it happens just after dialogue. Try and buff yourself up with potions/spells just before you enter her lair. Use some summonings (elementals, skeletons, etc) to distract her sahuagin allies. Get your arcane spellcasters down to the bottom of the screen so that they have a clear line of fire to her, as your melee fighters will probably be up against the wall to the north. Lower Resistance and Greater Malison spells will greatly help.
