Posted this on new player area but no one asnwered. Hoping general discussion will give me an answer. It says more health = more xp from bosses, but how is that calculated? And are there other factors determing how much xp gained, besides your level?
The exact calculation is a Kano Secret ™ but the closer you are in stats to the boss (Health, Attack and Defense) then the better the XP payout is.
It doesn't really matter. There are diminishing returns on XP once you get your bosses up to a certain level, but I keep doing them any way because I have nothing else to spend my stamina on.
