The heading says it all really. I've been wondering for a while if buffs and de buffs stack. I've asked a lot of players and the general response is a firm IDK!

For example, if I'm on my Mage and I use break armour on a boss, then another Mage (or any class with break armour) does the same, will it break armour by the sum total of our combined break armour ability or is the second break armour wasted. I often wonder the same when using Mage buff on party members. I know I get a better buff by buffing myself than by being buffed, but for other party members would they get double the benefit if two mages buff together or again, is second wasted?

Until I know otherwise, I am presuming they don't stack but it would be so useful to know. I look forward to finding out. Thanks guys.
