Plus, we have no idea how powerful Kraagor was or how well he would do against Serini's monsters. All we can say for sure is that a party consisting of a high epic level lich sorcerer, a cleric of at least 17th level, and whatever Oona and the MitD are come out of those dungeons looking pretty beat up. (See strip #1040). Seems unlikely that a single barbarian would be able to handily defeat those critters if a high-powered party like that has trouble.
