Ability Cooldown

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 in 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:

$C{R}_{Total}=1-\prod _{i=1}^n(1-C{R}_i)$

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

$C{R}_{Total}=1-(1-0.12)\times (1-0.16)\approx 26\mathrm{\%}$
