Yep, thanks.
As for AC and DC, I gave the Glabrezu a quick peek, and that's CR 9 (I think). My recollection of using a Glabrezu makes me want to outright switch its type rating with than the ineffectual Nalfeshnees I've used.
The point of the fight was to impress upon the characters that sometimes fighting is perhaps not the best solution (or at the very least not the quickest... in real-world play hours... :-/ ), now that they've graduated to big boy league.
We will see if they'll take the hint. There are some rather nasty upcoming opponents that might be best avoided. (Since this is based on 3E-era Dungeon adventures, the difficulty level is sharply different from 5E and OotA)
(Of course, all this is is theory - since there isn't much of a time pressure, all difficulty can be dialed down to minimum by just resting, but I'm doing all I can given what I have to work with)
How would the players react if they saw a large flock of vrocks coming to reinforce the caravan, or something similar? Given that they're on the demons' home turf, having more demons come to the aid of those in trouble seems like a strong possibility.....maybe that will have the desired effect and make the players think it would be better to run?
Especially if one of them is down already, and they've all used action surge and plenty of other resources, including the magic horn you gave them, on a meaningless battle. I'd think realizing that they're in the Abyss and hordes of demons may just keep coming at them would probably light a fire under them.
