I'm surprised (and rather impressed) that you managed to kill the guys in Nulb, although I guess players always find a way - albeit with some cheating in your case. At any rate, they're not meant to be fought at that stage. They didn't attack you during the hostel melee with Dala, did they?
I've seen it where if you were at 35500xp and gained a lot of xp it would go to 44999. Levelup to level 9, then the next xp gain levelup again to 10. Only 1 levelup at a time.
Not meant to be fought?? But .. but.. they're attackable =p Damn I didn't mess something up did I? No, they didn't attack me during the hotel rage thing. Anyway, its all about the ray of enfeeblement man. Spell owns. Admittedly the cheese silence REALLY helped, I doubt I could have beat them with their cleric running around healing the tanks. Plus the stupid AI had the cleric repeatedly attempting to cast his spells for most of the fight, despite the fact that he was silenced and couldn't do anything lol.
Basically everything in the game is attackable (chickens, children, etc.). If you just walked up and started whacking away, well, more power to you and I hope you had fun, but don't be surprised to see that's the end of it with them because they're dead now.
Thats one AI thing that can actually be fixed, thanks to Liv's last lot of efforts. Ray of Enfeeblment is definitely the bees knees, though.
Well since I killed them I won't ever know will I? Not planning on replaying this again, its too buggy.
