Guild Wars 2

It has no effect at all.
I dodged twice, then measured time till my endurance recharged with S/D, and there was no difference when I used the “Vigorous Scepter” trait and when I didn’t.

It’s pretty ironic I wanted to use it to replace the currently broken “Final Shielding” trait (that casts shield at useless 10% HP instead as the tooltip says at 25%), just to find out it’s bugged too, lol.

Try to test it out while your in combat. A lot of traits only work when your in combat. (haven’t tested this one myself though, as i’m not fond of scepter).
