Ability power (or AP) is a stat that increases the effectiveness of most champions' abilities. Abilities in League of Legends that are affected by ability power have an ability power ratio. This ratio determines how much a particular ability will benefit from a champion's total ability power, whether through increased damage, healing, and other numerical values. Ability power stacks additively.

Calculations To calculate the bonus to a numerical value in an ability, the formula is

Bonus = AP × AP ratio.

For example, if a damage spell has an ability power ratio of 0.25, every 4 points of ability power will increase the damage of this ability by 1. Abilities that are affected by ability power are identifiable by a bracketed plus sign with a green font, along with a number that corresponds to the applicable bonus. For example a champion with 50 ability power who has an ability with an ability power ratio of 0.7, it will display "+35" (50 × 0.7) next to the corresponding value in the UI.
