Basically, what Vulnerability buffs do is that they grant a chance to inflict more damage in certain situations. In Gray's case, there's a 15% chance to deal extra damage via Crits and EWD. It can help you reach the max damage cap if you're lucky.

As for the Critical Damage cap, I'm not so sure. I'll have to check a bit more, sorry.

I hope this helped! (ovo)/
