Health is a fundamental stat that determines a unit's hit points. When damage reduces health to 0, the unit dies. Health can be restored through regeneration, healing, lifesteal, and vamp effects.

Champions have base health that increases per level, plus bonus health from items, abilities, runes, and other sources. Maximum health is the total of base plus bonus health.

The health bar appears at the top of the HUD in green, showing current and maximum health. Different units display health bars differently:

  • Small units (wards, traps): Small bar marked per health point
  • Minions and lesser monsters: Small unmarked bar
  • Large monsters: Large segmented bar with exact health count
  • Structures: Large unmarked bar (turrets show segments while plating active)
  • Champions: Bar with 100-health marks and 1000-health segments

Gold Value: Health costs 2.67 gold per point.

Effective Health:

  • Physical = Health × (1 + 0.01 × Armor)
  • Magical = Health × (1 + 0.01 × MR)
  • Mixed = Based on damage type ratios

Some champions use health as a casting resource:

  • Briar, Dr. Mundo, Vladimir, Zac (primary resource)
  • Ivern, Olaf, Sion, Soraka (secondary resource)

Health can scale with:

  • Current HP%
  • Missing HP%
  • Maximum HP%
  • Bonus HP%

Grey health appears dark grey on the health bar to show recently taken damage for certain champions like Dr. Mundo, Pyke, Rengar, and Tahm Kench.

Health can be increased through items, champion abilities, and runes. Notable sources include:

Items:

  • Fimbulwinter
  • Heartsteel
  • Sundered Sky
  • Warmog's Armor

Champion Abilities:

  • Cho'Gath's Feast
  • Sion's Soul Furnace
  • Vladimir's Crimson Pact

Runes:

  • Grasp of the Undying
  • Overgrowth
  • Health shard

The highest possible health is 13,318 on a level 18 Ornn with optimal items, runes and buffs.
