Ranger: Both times, however, she fell quite quickly, as did her escorts, to a steady stream of Hell Spikes (at level 5 without ever taking a point in the skill--lots of nice books). When she would blind me, I'd suck a shadow potion and stand around until the blind wore off, being able to then hit her with 3 or so Hell Spikes before being blinded again. She fell easily both times (though was still one of the game's hardest fights
Warriors use a shadow potion and then the Whirl attack not ON but near her
Use Aura of Command on her deadknight and hit her with a frost weapon, blinding her, too - so she can't summon more
Mage: Curse her several times (survivor spell) to set down her resistances, then freeze, life leech and elemental strike
Summon skeletons to distract her and hellspikes
deadly discs standing near to her so the radius can get her and her deadknights
Survivors: Scorpion traps.
