I've played for a while now. And what I can see about bonds is, there is a chance for every skill you use after you put the bond up, to break it. I just got the 10% damage and that holds up for like one attack. Even if I dont use any skills. And the heal over time bond, is very much random it looks like.
What I want to know is, what attribute affects the bonds ability to stay up? =P Anyone know?
I mean logically it should be wisdom I spose, but I really have no idea

might be int because jesus I can only use like my first bond that stays on til its duration runs out and not feel cheated :P
