Witch Hunter is a hard game to heal in. Thats not bad, but I think the game needs a bit more. How about a healing prayer?
Lay on Hands
True Faith: 1
Description: This Rite channels the power of god directly into the target to mend their wounds. When a character casts a spell, the time the spells takes is equal to one hour divided by their True Faith score. At the end of the time, the caster makes a Prayer check with the difficulty equal to their damnation score. If the caster succeeds, the target of the spell heals one wound with one additional wound for every success.
Boost: Increase the Mastery by 3 to heal one additional wound.
