pg. 122 (Core Rules) under Recovering from Damage says that characters recover all lost vigour after an action scene, and that they may spend 1 momentum (I,R) during a scene to recover 1 vigour.
It then says characters are able to take an action to recover their own or allies vigour using the Healing skill.
However the Healing skill description on pg. 66 doesn’t elaborate on the mechanics of this?
Is there another section I’m missing or ?
