Just thought I'd throw this in....... If you have the Periapt Of Life Protection it will gaurd against all of Irenicus death magic.
Also, if you keep getting waxed, go back and finish some other quests to gain a couple levels. This will help you with your saving throws and make his magic less potent against you. I think my monk has a save of 1 versus death magic. know what I mean now???
Anyway, Good luck
