Note on "condition stoppers": Because of my party's make-up and the Pacifist Cleric's tendency to not miss (I never seem to get to see his dice rolls), I had to give most of my Solos a save at the beginning of the turn, in addition to the end, or they'd never get to do anything at all. In some cases I allowed that save to work on conditions that a save couldn't end.
Unfortunately, in the case of Acererak, the melee characters managed to just rush in and wail on him, pretty much before he could do much. Very anti-climactic.
That's what happened for me, but since Acererak has lots of bursts and blasts, I found no problem with hit. I try to give solos a selection effect removal, just so it isn't dull and predictable, mostly I want to allow effects to be useful but cripple the monster.
Is anyone else having trouble with the links? I click on them, and then it just takes me to the home page of all EN forums.
One of my long term projects is to rewrite the entire module from start to finish with MM3 updates / clearing up encounter issues.
