Guild Wars 2

I have 32% crit chance. I see it successfully go up to 82% when I am in shroud, but it does not seem to change at all based on whether I am hitting vulnerable foes.

The 50% increase you see in shroud is from Death Perception.
Decimate Defenses is calculated individually for every enemy and therefore does not show up in your hero panel.

Right, I know the 50% was from DP, sorry I was not clear. Thanks for the explanation, didn’t realize it doesn’t show up in the hero panel.
