For restoring a champion's health in general, see Healing.

Heal is a summoner spell that instantly restores health to your champion and an ally, also granting a temporary movement speed bonus.


This spell can be used to save a life when low on health and under attack. It is commonly used to get an early first blood by healing oneself for more than one's opponent expects. It is also a skill used for "baiting", where you make your champion appear weaker than it actually is, to lure your enemies out of position or to get them to tower dive you. A similar baiting tactic is also commonly used with Barrier Barrier.

This summoner spell is considered by many to be vastly superior to Barrier Barrier for a number of reasons - the heal is permanent, affects two people instead of one, and gives a 30% speed boost to yourself and your ally. However, Barrier is not affected by Grievous Wounds icon Grievous Wounds, has a shorter cooldown, blocks more damage (against a single target), and can be used while you're still at full health (good against 100-to-0 burst).


  • Healed champions are debuffed for 35 seconds, causing subsequent Heal casts on them to be 50% less effective for that period.
  • Heal is affected by any form of personal health gain modifier on yourself (but only yourself), including:
  • The cooldown of this spell can be reduced by the Cosmic Insight rune Cosmic Insight mastery or by Ionian Boots of Lucidity item Ionian Boots of Lucidity.

The following table compares the effectiveness of Barrier Barrier vs Heal Heal on a target affected by Ignite Ignite.

Barrier Barrier will always negate 40% of Ignite Ignite's damage if it is activated while under the effect of Ignite Ignite for at least 2 seconds. Heal Heal will always negate more damage than Barrier Barrier. Note that Heal Heal will absorb a larger portion of Ignite Ignite's damage at lower levels.
