[Bozos of Bones]

I had the same restoration-won't-cure-energy-drain problem. Just download the last patch and it will fix the problem.
P.S.
Death Ward will immunize you only to the death part of a spell. A Finger of Death will automatically give 3d6+level points of magic damage to a target protected by Death Ward. If I see someone casting Death Ward, I usually Harm them. Harm is a great spell.
