Guild Wars 2

The trait is supposed to increase endurance regen by 50%
while wielding a scepter.

Out of combat, this doesn’t work at all even though tooltip
doesn’t state that. IN combat, and using a timer, the increase
is 25-30%. In fact, the results on this seem different each time.

Anyone else notice anything different?

First it does not work out of combat (see the wiki).

Second, your max endurance regeneration is capped at 100%. So it will not stack with the Vigor boon.

I understand both of those points, but it doesn’t explain
why the regen is not 50%. Time it on your iphone timer,
its clearly not 50% (and I don’t have vigor on).

Actually that would be an interesting change to the trait.. If it were to give you three endurance bars instead of two, but keep regen at the same.

You could use your third dodge roll in an emergency, then between fights it would recharge back up to three.
