The group was going up against a high level cleric. It was a pretty fair fight, he was very tough, but they were tough enough, and I am not real good at running spell casters. I did have one quick trick. The cleric took a look around and figured which character would be able to do the most damage the quickest, in this case it was Kevin's fighter-type. So as they approached, he reached out and touched him and threw a Harm spell, leaving Kevin with 2 hit points. The argument on his side consisted of "I would never let a high level cleric touch me". "He rolled to hit and made his roll." "He didn't hit me, he just touched me." Over and over. Do you see a pattern? Once again his entire group started in on him.

And a Kevin postscript
In all fairness I do have to bring up his one good moment. And I mean ONE good moment. We wanted to ransack a temple. He said "leave this to me". He walked up to the back of the temple and cast Stone To Mud. The back wall came down. He then cast Dispel Magic at which point the mud changed back to stone and he said "let's go". We all stared at him in amazement.

Tomorrow ... an entire Call Of Cthuhlu groups loses sanity ... the players, not the characters
