Hi,

i am assassin deception and i was wondering if charge mastery stack with another "debuff" for armor, like sunder armor from Jug, BH or/and assassin Darkness???

If the target got all 3 debuffs i will still getting benefit of 9% from Charge Mastery?

Thank you.

I believe only the same effects don't stack e.g if you have 2 warriors you don't get double the sunder. So it should stack yes.

I don't believe that's entirely accurate. The way it works is that the highest rebuff of that type sticks, ie. If tracer missile has a 20 armor rebuff and say sunder has 30% than sunder would be the standing rebuff for armor. If it worked the other way bosses would have negitive armor if you brought all different classes lol.
