it's funny, in 2ed of DnD I'm fairly sure red dragons are supposed to be way tougher than other chromatics, I guess the developers of bg 2 didn't exactly followed this.
Wait, I didn't even know there were purple dragon in this game. Did they put them in the game? I remember Abazigal being able to cast Kai and Whirlwind, and it looks like the script isn't working properly.
Thanks for the comment. Yea, in many battles, if the monster is put under player control, the scripts don't work, unfortunately :) I am wondering, if one purple dragon is in Watcher's Keep, or perhaps it was just made but not used. If I remember correctly, the stats are rather similar with some other dragon, was it Firkraag?
