Healing

Healing is the action of replenishing a unit's current health, distinct from the other forms of health restoration (life steal, spell vamp and health regeneration). It can be weakened by healing reduction.

Healing cannot increase a unit's current health over its maximum. The act of leveling up and certain champion abilities (such as Lulu's Wild Growth) will increase a unit's current health by the same amount as the increase to their maximum health, but this is not considered a form of healing. As a result, they are not affected by healing reduction.

General

• Leveling up will restore some maximum health, and some current health. Actual health regained is lower depending on how wounded the champion is upon leveling up.

Map-related

• On Summoner's Rift and Crystal Scar, standing the summoning platform restores health each second.
• Picking a Health Relic on the Howling Abyss.

Runes

Healing reduction

• Grievous Wounds is a debuff that reduces all healing received.
• The Howling Abyss map reduces all outsourced healing and regeneration effects by 50%.

Preventing healing

• Kindred's Lamb's Respite negates all healing effects on a unit once they've reached a certain health threshold.

Notes

• If a champion dies but immediately after continues active for one ability's champion (ex. Zilean's Chronoshift and  Sion's Glory in Death) all debuffs disappear, so the consequent heal won't be affected by Grievous Wounds.
• Note that Sion's Glory in Death heals him back up to 100% maximum health; no healing buffs or debuffs affect this healing.

Trivia

• Before V9.9, Aatrox's Deathbringer Stance could inflict Mutilator against enemy champions.
• In a role-play setting, healing may represent anything from attending to battle wounds to repairing damaged hardware to replenishing a magical spell that holds a construct together, but outside of its physical representation, its effect is always the same - it serves as a direct increase to a unit's current health.
• Healing can be viewed as the polar opposite of damage. Unlike sources of damage, however, sources of healing are uncommon and the majority cannot be used to heal others - and those that can frequently have large ulterior costs to use.
• Any healing in-game that restores less than 20 health is not shown as the usual +X green text.
