OOC:
Mike, take a look at my post in the OOC Thread - Skáth may Heal each wound once, regardless of how many points he manages to give back. Attempts in which he fails his healing skill roll count against his total attempts for the day, but do not count as Healing that wound.
Target number is his Healing skill roll, minus 2 for each die he puts into the healing attempt. If he wishes to make a Healing skill roll prior to each attempt to heal, he may add one back to the target number of his magical healing attempt for each point he makes that skill roll by.
