Healing

Healing refers to the ability to restore health to a unit. Healing (heals) are distinct from other forms of health restoration (life steal, spell vamp and health regeneration). Healing cannot restore a unit's health over its maximum, as with all other health restoration. Healing also does not refer to maximum health gained from abilities.
