Something is bothering me with this action. I like the concept of being able to recover a bit of fatigue and strife in action, but I feel this action need limitations.
Whats stops my players to say ''I'm gonna use calming breath for 10 minutes'' durring any non-conflict scene, to remove all their strife and fatigue?
I just cannot tell them ''this action only works in conflict'', that doesn't make sense ! if you can ''calm breath'' in combat, you can do it any other time.
