The problem is it's difficult to run two big encounters in the same in-game day. Ideally, I think there would have been an extended rest between these two encounters, but I didn't design this part of the campaign. I'm starting to think I should be modifying more of the already slightly modified campaign, though I don't think anyone in the group could have known how ragged everyone would be run from these back to back fights. Part of the problem is there wasn't enough healing going around, which is a problem in small groups with only one healer. I tried to mitigate this a bit with the bonus abilities granted last encounter, but the issue persists. The Paladin got sandwiched by enemies, so he couldn't really use Lay on Hands much (though he really only needed to heal himself, mostly). The Artificer only has two uses of his healing power for encounter. And Cal has his own new encounter utility power (Incite Faith) which would have granted some THP and allowed some useful shifts (maybe mark it on your sheet?)
