What does grey bar on the character represent?

[Kligan]

In combat there are two bars under character's HP - one is blue, and one is grey. They both fill in, and deplete when character attacks. However, the blue one deplete completely on attack (so that must be an attack cooldown), but the grey bar depletes partially. And sometimes the grey bar depletes even more and turns red.
What does this grey bar represents?

The grey one is overall stamina, when you run out and it turns red, you’re out of stamina, reducing your stats (evasion and counter mostly, I think) until it fills up again.

It seems to mostly exist to balance out evade/counter builds.

So evading and countering depletes the grey stamina bar?
The game didn't mention anything about it. I think it should...

I was just about to make a post with the same question. I really should be mentioned somewhere in the game.

It doesn't explain things like specific combinations of cards doing something different either but is deducible through playing the game rather quickly.

It also decreases each time you attack, so having a huge attack speed bonus is actually problematic sometimes as well. You basically gotta balance out the 3 things that impact it.

Stamina:
max 100, starts at 100
regen 15/sec
-25/attack (counter attacks do not use stamina)
(warrior base attack speed is 0.6, so regens as fast as it is used)
evade -10
get hit +10
