Ability power

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.
