Guild Wars 2

I was comparing my stats in-game with the one I made through gw2 build editor and noticed that in-game, static shot only gives 1 stack of confusion when it was 2 in the editor. Pry bar also seems to do less confusion damage in game compared to the editor.

does anyone know when these changes were made?

Static shot applies 2 stacks when I test it in pve.
You can calculate your confusion damage with the formulas found here.

Static shot usually applies 2 stacks confusion.
But if you have chemical rounds traited, this skill is bugged and applies only 1 stack.
