Cooldown reduction effects the rate of which ablilities can be used, as well as summoner spells (ex. Flash, Teleport, Ignite, Etc.) Cooldown reduction like all other stats, can be gained via items, runes, masteries, and through blue buff.
It works at a flat rate, reducing the seconds by your percentage of cooldown reduction.
- For example, 10% cooldown reduction would lower a 10 second recharge time by 1 second.
The max cooldown reduction allowed is 40%.
