Convalescence Bug

Hi, I have a problem with the Convalescence.When I use it, it only works for about one second and then turns off, even though I haven’t taken any damage and my ES hasn’t fully regenerated.

The buff duration is between 3-4s ish (Base)
If you have thing that reduce the duration of you skill by like 75%... Then it probably the reason.

Or your consider full ES for whatever reason, before reaching max and then it stop.
Or you take a hit you didn't see, that cause a debuff that then drain your ES faster than it regen...
Or you got debuff with an anti regain.

I can't confirm anything but just thing to validate.
