Ability power (AP) is a stat that increases the effectiveness of some items, abilities, and runes.

Every champion starts with 0 ability power, and level-ups do not grant additional ability power.

Ability power can be increased with items, abilities and runes, it stacks additively, and each bonus point acquired directly affects its statistic.

Effects that benefit from ability power receive a bonus based on a certain percentage of the 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).

Gold Value

  • Ability power has a gold value of Gold 21.75 per point.

Relevant mathematics:

  • Items = Amplifying Tome item 20 + Prototype Hex Core item 1 = 21 AP
  • Runes = Inspiration icon 22 + Absolute Focus rune 5 + Waterwalking rune 5 + Kleptomancy rune Kleptomancy (Elixir of Fortitude item 10 + Travel Size Elixir of Sorcery item 25) = 67 AP
  • AP Multiplier = 1 + Blood Boil 0.4 = 1.4
    • AP = (21 + 67) × 1.4 = 123.2 AP
