Good Question!The Amount of damage taken is the sum of the even numbers rolled in a combo. So if you are in a combo and roll a 2, 6, 4, 3 then the combo would end on the odd 3 as a miss and the dmg you opponent has taken is 12 (2+4+6).
Nice! I thought it might be something like that! :D I look forward to using this system for skirmishes!
