It has been suggested that Cooldown be merged into this article or section.
Cooldown reduction (abbreviated as CDR) is a champion statistic that reduces the cooldown of abilities, or the amount of time you must wait before an ability can be used again once you activated it, by a percentage.
Cooldown reduction is granted by items, buffs, runes and masteries, as well as some passive abilities.
Cooldown reduction works additively. If you have a 6% cooldown reduction from masteries, and a 10% cooldown reduction fromyou will have a 16% cooldown reduction. Cooldown reduction cannot be increased beyond 40% by absolutely any means.
Cooldown reduction is unique among the same item. So 2(+25%) will only grant the bonus of +25%, but a (+25%) and a (+10%) will grant a +35% bonus.
Cooldown reduction is determined at the moment an ability is activated. Increasing/decreasing your cooldown reduction while the skill is on cooldown will not affect the cooldown.
Cooldown reduction does not apply on item active abilities such as those ofor .
