2 attempts on the Chimera. 2nd attempt they knew what they were in for and planned accordingly. 4 attacks plus the breath weapon just shreds one or more PC per turn.
I suppose party make up may have to do with it. No Wiz. 1 Fighter. 2 Clerics though 1 couldn't cast Cure Wounds. It was...
Was this overpowered?
Chimera. Level 10 monster. VS 7 PC's with a total of 12 levels.
The Chimera tore them apart. 4 attacks at +7 for 2D8 PLUS a breath weapon DC15 for 4D6? 4 died and the other 3 barely lived and probably would have died had initiative been in my favor.
By compassion...
