Ability power icon.png Ability power (AP) is a stat that boosts the effects of some items, abilities, and runes. Those effects receive a bonus proportional to the ability power of the champion. For example, if a champion has 50 ability power and one of their spells deals 100 (+20% AP) damage, the damage of the spell is 110. The spell descriptions in the game do not show that percentage, they show the resulting bonus. The description of the spell in this example would show the damage of the spell as 100 (+10).

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 Additive stacking icon.png stacks additively, and each bonus point acquired directly affects its statistic.
