The mage can forestall the death of a dying ally, perhaps enough to get some more lasting help.
A lesser version of Healing Heart, this at least offsets the accrued damage inccured while Incapacitated, giving allies one less worry while they're dealing with the situation they're in. Even if the last health box is filled with lethal damage, your target is no longer bleeding to death (but is still unconscious) and damage no longer upgrades from lethal to aggravated provided no further damage is taken.
This Spell lasts for one turn per success, at which point the regular Incapacitation status kicks back in at full force.
