Healing

Healing refers to the ability to restore health to a unit. Healing (heals) are distinct from other forms of health restoration, such as life steal or regeneration. Healing cannot restore a unit's health over its maximum, as with all other health restoration. In addition, life steal and spell vamp are considered different types of healing, and have their own articles you can refer to.
