生命回复

 Health regeneration (also known as HP5) is a stat similar to mana regeneration which determines the amount of health a champion regenerates over a five-second period. This happens in half-second intervals. Health regeneration is considered to be a form of healing for the purposes of healing increases or decreases, and for the sake of the "Healing Done" stat at the end of game screen.

Each champion starts with a certain base rate of health regeneration, which increases by a small amount at each level-up.

Health regeneration can be further increased by a variety of items, abilities, runes and neutral buffs. Health regeneration stacks additively, and each bonus point acquired directly affects its statistic. This is true whether the bonus is a flat value or percentage-based.

Gold Value ​​​

• Flat health regeneration has a gold value of 36  per point.
• Percentage base health regeneration has a gold value of 3  per point.
• Health restored by potion has a gold value of 0.233  per point.

Restoring Health

Health can also be restored through others means than health regeneration: healing, life steal, and spell vamp.

Trivia

Last updated: July 29, 2020, patch V10.15

Without using Grasp of the Undying, Overgrowth, Cho'Gath's Feast, Sion's Soul Furnace, Ravenous Flock or Vladimir with Gathering Storm which potentially allow for infinite amounts of health, what may be the highest health regeneration attainable is 19329 health per 5 seconds, with Dr. Mundo's, thanks to his passive Adrenaline Rush, and his ultimate Sadism, which both scale with maximum health.

Note that Revitalize and File:Heal power.png Heal and Shield Power do not affect health regeneration, and that Oceanic Will and Ocean Dragon Soul are not considered as health regeneration effects.

• Base stats: 2095.52 health and 20.75 health regeneration
• Runes:
  • Second Wind
  • Biscuit Delivery
  • Health rune shard
• Items:
  • 3 × Warmog's Armor
  • 1 × Spirit Visage
  • 1 × Cinderhulk
  • 1 × Gargoyle Stoneplate
  • 1 × Elixir of Iron (consumed)
• Other Buffs:
  • Dr. Mundo is at 0.01% of his maximum health
  • Total Biscuit of Everlasting Will (consumed)
  • Crest of Cinders
  • Dr. Mundo's Adrenaline Rush
  • Dr. Mundo's Sadism
  • Lulu's Wild Growth (with the maximum amount of ability power, with a Yuumi)
  • / Tooth and Nail
  • An additional potion ( ) cannot be consumed because Dr. Mundo's inventory is full.

• Lulu:
  • Items = 175 + 120 × 2 + 120 + 80 + 145 + 136.55 = 896.55 AP
    • Seraph's Embrace's AP = 50 + ( 1285 + 200 + 1400) × 0.03 = 136.55 AP
  • Runes = 50.4 + 30 + 30 + 9 × 2 = 128.4 AP
  • Buffs = 20 + 80 + 50 = 150 AP
  • AP Multiplier = 1 + 0.4 + 0.2 + 0.16 = 1.76
    • Lulu's AP = (896.55 + 128.4 + 150) × 1.76 = 2067.912 AP
    • Wild Growth's bonus health = 600 + 0.5 × 2067.912 = 1633.956 health

• Dr. Mundo (health):
  • Items = 800 × 3 + 450 + 300 = 3150 health
  • Runes = 90 = 90 health
  • Buffs = 1633.956 + 300 = 1933.956 health
  • Maximum Health Multiplier = 1 + 1 = 2
  • Bonus Health Multiplier = 1 + 0.15 = 1.15
    • Dr. Mundo's health = (2095.52 + (3150 + 90 + 1933.956) × 1.15) × 2 = 16091.1388 health

• Dr. Mundo's (health regeneration):
  • Base = 20.75
  • Items = 25% max health + 200% × 3 + 100% = 25% max health + 700% base HP5
  • Buffs = 41.6667% max health + 11.9988% max health + 9% max health + 1.9998% max health + 1.5% max health + 30 + 3 = 66.1653% max health HP5 + 33 flat HP5
  • Health Regen Multiplier = 1 + 0.3 = 1.3
    • Dr. Mundo's Health Regeneration = (20.75 × (1 + 7) + 33 + (16091.1388 × 0.911653)) × 1.3 = 19329.09544856732 health regeneration
      • Or 3866 health per second.

• In the same situation, Dr. Mundo is at 0.01% maximum health so he has currently about 1.6 health.
  • It would take him 4.16 seconds to recover all his missing health.
