This is a funky kind of math here. I know even before masterys bard got a split of the damage. Its not the mastery doing it. IDK what the percentage is but when I have a dark father discorded and provoked with all sorts of baddies and another play comes in, specifically a chived up slayered maxed out warrior, I start seeing numbers like 186 and 252 start flyin. I am not partyed with these players and I cant be sure they even get credit for that damage but, I am sure we bards get our fair split and then some.
