I know I'm missing something here. I've killed the lich, made it past the riddle bridge, killed the little beholders, and I'm now inside a temple with an alter. When I go inside there is a daemon who I can't seem to kill. What am I missing? Thanks for the help.

Heal It with Cure spells

Ahhh - would never of thought of that. Must of missed that part of the dialog with the diseased guy out front. Does he need a healing as well? Also, when I killed the lich just before this area he didn't drop anything. I thought he was supposed to drop part of the rod. Thanks for the help.
