I think maybe there is a bug with the Boss helper rewards on some of the higher Boss fights. I have got the rewards a couple of times even if I didnt do more than one attack and was'nt near the minimum damage I need to do to get the reward.. http://i443.photobucket.com/albums/qq153/Spirillen/La%20Cosa%20Nostra/Wongsawat.jpg
not sure on this but ive noticed if the boss dont have much helpers in it usually even the smallest damage will get you the helper reward
