A better alternative to "spiritual healing" would be talents that require high spirituality, mysticism and a specific injury to acquire. The talent would either offset the injury penalty (Heightened sense: Through intense mediation your remaining senses have been heightened, the lost of your eye no longer concerns you) or gives an alternate bonus (Efficient Dodge: Your decreased stamina from your injured heart has forced you to make the most of the strength you have, by minimizing your movements, you no longer become fatigued while dodging). Of course, you would have to have one for the villains, I'm thinking
Spread the suffering: Requires high spirituality, mysticism, villainous and any injury to acquire. Allows a Martial Arts technique that temporarily inflicts your injury on the target (or a random one if you have more than one).
