Ability power (AP) is a champion statistic that increases the effectiveness of most abilities. It stacks additively.

Effects that benefit from ability power receive a bonus based on a certain percentage of a champion's current ability power. For example, if a spell deals 100 (+20% AP) damage and a champion has 50 ability power, the spell's damage will increase by 10. In-game, spell descriptions do not display the percentage, but do display the resulting bonus; the previous example would display as 100 (+10).

Ability power has a theoretical gold value of 21.75 Gold per unit. This means that Needlessly Large Rod item.png Needlessly Large Rod is the most efficient AP core item, with a gold/AP ratio of 20.833∞.The costs of these stats are always offset by increased final costs of their upgraded items.

Trivia

  • The ability with the largest AP ratio is Annie Annie's Summon- Tibbers.png Summon: Tibbers, with a maximum AP ratio of (+ 515% AP) counting initial cast of (+ 65% AP) and the target taking damage from all 45 ticks of tibbers aura damage ((+ 10% AP) per tick).
  • The second and third bounces of Nami Nami's Ebb and Flow.png Ebb and Flow scale exponentially, however the low base ratio means it will not beat other spells at normal levels of AP.
  • Darius Darius, Draven Draven, Garen Garen, Illaoi Illaoi, Kalista Kalista, Kindred Kindred, Olaf Olaf, Riven Riven, Talon Talon, Vayne Vayne, and Zed Zed have no abilities or innate effects that scale with ability power.

Aside from Veigar Veigar and Thresh Thresh, who may obtain theoretically infinite ability power due to their respective passive effects, and Galio Galio, interacting with Runic Skin.png Runic Skin and a metagame mechanic not intended to be seen in gameplay (bonus magic resistance when disconnected), the highest attainable ability power by a playable champion on Summoner's Rift is still on Galio Galio thanks to his passive, Runic Skin.png Runic Skin.

To reach this amount there are 5 nearby enemy players and 3 allied players needed, who play Braum Braum, Orianna Orianna and Janna Janna.

Galio Galio must:
Janna Janna must:
Orianna Orianna must:
Braum Braum must:
This combination will result in Galio Galio having about 2344 ability power.
Relevant mathematics:
Galio Galio's ability power = (15 + 83.16 + 40 + 145 + 120 × 4 + 151.04 + 50 + 173.45) × (1.36 + 1.35 + 1.15 + 1.2) = 2344.43
  • Braum Braum's additional magic resistance = (70 × 6 + 15 + 15 + 11 + 73.44) × 1.05 = 561.16
  • Ability Power gained by Runic Skin.png Runic Skin = (54,6 + 30 + 90 + 11 + 15 + 15 + 114.79 × 1.05) ÷ 2 = 173.45
  • Full rune page of Scaling Ability Power runes = (1.8 × 9) + (1.8 × 9) + (3.06 × 9) + (7.74 × 3) = 83.16
  • Full rune page of Scaling Magic Resistance runes = (1.26 × 9) + (1.8 × 9) + (2.88 × 9) + (6.66 × 3) = 73.44

This combination will result in Galio Galio having 129.2032153 ability power.
Relevant mathematics:
Braum Braum's bonus magic resist = (5 + 5 × 3 + 0.77 × 9 + 0.74 × 9 + 1.34 × 9 + 4 × 9 + 25) × 1.10 = 117.315
Galio Galio's magic resist = ((5 + 30 + (15 + 117.315 × 0.1) + 10 + 10) × 1.075) + 32.1 = 119.9613625
Galio Galio's ability power = (0.89 + 6 + 0.59 × 9 + 0.59 × 9 + 1.19 × 9 + 4.95 × 3 + 20 + (119.9613625 × 0.5)) × 1.05 = 129.2032153
