If the CR3 (bear, I suppose, altho I had guessed them to be more difficult than standard black bears, similar to the wolves we had encountered who had been quite nasty) would have had a chance to act, they could have caused some trouble at least. Surely not life-threatening, but not insignificant either.
I'm pretty sure, that the encounter would have been A LOT tougher, if we didn't have been able to surprise them and prepare ahead.
We were looking at huge room for Donner to charge (which makes him like twice effective

), two reasonably dangerous opponents (including the single most dangerous one) being out of the fight before they could act even once, and then what was left? Three CR 4 cultists and one CR 3 bear (the Zombies can be ignored pretty much, yeah) against six level 5 PCs (not counting Folco) plus an NPC. Of course, we were wiping the floor with them.
With less room to maneuver and without surprise, the bears would have joined in at least and maybe the fireball wouldn't have gone off. The leader would still have ended up in a cocoon, I guess, tho. She failed her save after all.
Still it would have been quite a bit more dangerous then.
With Dara, we are talking a difference of 8 Str points for any further encounters, which translates to 14 points of damage with the same attack bonus! That's roughly 50-60% less effectiveness in combat, so to say!
I'd guess the spellcasters used up even more of their effectiveness this day already, not sure how many manifestations Ian has left, but he used up quite a few as well.
So, what am I saying basically... it wasn't really the opposition, but rather the situation, which made this look so incredibly easy.
