Cooldown Reduction (abbreviated as CDR) was a hero 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. The stat is granted by some of the cards as an Unique Passive or Active.
Cooldown reduction is determined at the moment an ability was activated. Increasing/decreasing your cooldown reduction while the skill is on cooldown will not affect the cooldown. Cooldown reduction does not apply on card active abilities or card passive effects with cooldowns.
Stacking Cooldown Reduction Cards
Some CDR cards, when combined with others, allow the hero to get more than 10% CDR (up to 30% CDR max)
