[Cerek the Barbaric]

I had similar success with the Improved Demagorgon - after about 6 re-loads. I'm playing a Wizard Slayer dualed to a thief (24/26). So he and Jan had set as many Spike Traps as the game would allow. Sometimes they did good damage...sometimes they didn't. Finally, all the traps went off and did excellent damage (Jan's trap did 87pts by itself - my three did around 70-75 each). As soon as the Time Stop ended, the traps went off and Demagorgon was NEAR DEATH before the fight ever really began. One round of attacks from my Wizard Slayer and Minsc took him down for good. After that, the Marileth's weren't very difficult at all.
