I cleared the Crypt of Drath without any problems but cannot get Drath killed (level 18 party, normal difficulty). Lured out all other mobs in his room and killed them without triggering Drath himself but even though I fight him alone it does not work out (my dmg seems very low).
I'd be fine with coming back later, but it seems I cannot get out through the teleporter maze. My last save before entering the crypt is a couple hours old, so I'd lose quite some progress if I went back to that.
So,
1. can Drath be killed on level 18?
2. can I get out?
Thanks everyone!
