Ability CooldownGive feedback

Ability Cooldown is the time it takes for an Ability to be usable again.

Overview

Cooldowns range from a few seconds, as in Lady Geist's Malice, to a few minutes, as Dynamo's Singularity. Ability cooldowns can be reduced by acquiring the Cooldown Reduction stat, which reduces the cooldown by a percentage of base ability time.

Charged Abilities

Some abilities can acquire multiple charges. In those cases, the ability cooldown represents the time for a charge to become available again after being used. This should not be confused with the time between charges, which describes the delay after using a charge that a different charge can be used.

Stacking

Despite being presented in-game as +X% Cooldown Reduction, different sources of cooldown reduction stack multiplicatively, not additively. With $n$ different sources of cooldown reduction, total cooldown reduction is given by:

$C R_{T o t a l} = 1 - \prod_{i = 1}^{n} (1 - C R_{i})$

For example, with 12% Cooldown Reduction from Diviner's Kevlar and 16% Cooldown Reduction from Improved Cooldown, total cooldown reduction is:

$C R_{T o t a l} = 1 - (1 - 0.12) \times (1 - 0.16) \approx 26 %$
