I had a party fighting the improved "imprisoned one". My PC is a fighter dual mage and I had Jan too, and they both had simulacrums going. I used the helm of vailor to give anomen a sim (this is fun), so that I had anomen x2 summoning skeleton warriors, casting greater restores, bolts of glory, and storms of vengeances from both sides of the room...the real jan ran out of spells that would do any good, so I had him cast Maze on a Marilith to help clean up the big mess in the center. Anomen One and Anomen Two both landed Bolts of Glory on the imprisoned one, and finished him off. I cast tensors on my fighter mage and ran in to fight the remaining glabrezus and mariliths, and after a little bit the group finished them all off...
Then suddenly, as everyone was heaving a big sigh of relief, this stupid marilith appears right in the middle of the group, back from its maze. They all strike down on it and kill it in a few seconds...It was just like a movie where you think the villains dead, then they suddenly jump up again, and the heroes knock em off the world trade center...
Well I thought it was funny anyway

May you walk on warrrrm sannd....
