I agree, the Underdark is beautiful. If not for that pescy bulette, it would be perfect.
There is a bug with the ball throwing? I never encountered any problems.
I'm not sure if it counts as a bug, but my druid managed to accidentally hit Scratch once and he turned hostile, and then the entire camp went mortal combat. Maybe they could make it so that the ball deals no damage and therefore doesn't count as a weapon.
But I have a funny moment caused by this "mortal combat" behaviour of npcs that are not in the party. On an evil playthrough attempt my pc attacked the fishermen as they were running away. This happened in Astarion's line of sight, who turned hostile, shouted something about not getting away with this and tried to defend them.
