Trauma

When you use a skill and push the roll, you can suffer trauma. This temporarily reduces the attribute score you used for the skill. If your attribute score reaches zero you are broken – unable to get up on your feet or use any skill for D6 hours or until someone Heals you. At that point, you regain one attribute point and can recover normally.

Recovery: The requirements for recovery depends on type of trauma:

Damage (trauma to Strength): Some rest and a ration of grub per trauma point.
Fatigue (trauma to Agility): Some rest and a ration of grub per trauma point.
Confusion (trauma to Wits): At least four hours of sleep.
Doubt (trauma to Empathy): A moment of closeness with another mutant. It can be a talk by the campfire, a moment of shared silence, or physical contact.
