ok, pardon me, but our math seems off about Blazing aura.
if the Brawl index is .6111, then with six Single origins... your equation
(.6111*1)+(6*.333)
would equal 2.6091
Multiplying that by a 30 damage brawl you get 78.273 damage.
assuming one Accuracy and one Endurance Reduction, four damage enhancements would yeild 58.293 damage at a 30 damage brawl ((.6111*1)+(4*.333))*30.
Is there something I'm missing as to why your numbers are lower?
