Mage spells for Josie:
Blind her and then elemental strike/elemental hail, highleved
Curse her (survivor) several times, lifeleech, frost, elemental...
Or take my tactic:
Deadly Discs highleveled, changing the radius when she moves, so I can kill her deathknights and hurt her at the same time. A wee pause in between, so my mage can jump off those spikes and a lot of restoration potions.
Blind her + aura of command on her deathknights, they will tackle her
shield yourself with both spells, if she blinds you, drink a shadow potion or fade from sight
Good luck, she's hard <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
