The Skill of Healing gives a Character the ability to cure wounds and reduce crippling injury. One must make use of bandages or medical kits in order to Heal someone, and each use of the Skill will deplete some of your supplies. A critical success can do a great deal of good to an injured person, but a critical failure will Heal nothing and use up more the usual measure of one's Healing supplies.

Heal Apprentice: a Character may heal an extra 50%

Heal Expert: critical failures are merely failures (and thus do not use extra bandages)

Heal Master: all successes are critical successes (and will Heal side effects of a crippling injury)
