I've found in most combat against ogers and a few other AI monsters that the monster just stands there and you get turn after turn to tickle it to death.
Also the Abraxis combat is still screwed up. It just sat there too after casting fear if I recall and then combat keep freezing up. If it climbed out of the crack and came to get you it would be far more effective, otherwise a few archers can pelt it to death. Or if it had a unique long range attack...???
Also the Abraxis zone of control (green area on map) didn't go away after I killed him and everything else I could find in the area.
