Besides sacrificing him on the alter and activating all of those demon knights, is there any other way to kill this irritating little froglet. My finger got tired from beating on him so long. I can't find the message on the boards but I think I read something about him here before.

I beat on him for a while and was surprised that when he died he was only worth 4000 XP. Anyway, I used the Vorpal weapon (+3) and he eventually "ghosted" meaning I cut his head off.
