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.

In the in-game HUD, ability cooldowns only show decimal values below 2s.

Unlike Ability Range and Ability Duration, ability cooldown does not affect items. Items are only affected by a separate stat called Item Cooldown Reduction which is granted by Transcendent Cooldown.

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.

Calculation

Calculating Cooldown Reduction

Despite being presented in-game as +X% Cooldown Reduction, multiple sources stack multiplicatively, not additively:

$\text{Total Cooldown Reduction}=1-(1-C{R}_1)\times (1-C{R}_2)\dots$

Example: With 20% from Superior Cooldown and 5% from Spellslinger:

1. Convert percentages to decimals: 20% to 0.2 and 5% to 0.05.
2. Subtract from 1: (1 - 0.2) = 0.8 and (1 - 0.05) = 0.95.
3. Multiply the remainders: 0.8 × 0.95 = 0.76.
4. Subtract from 1: 1 - 0.76 = 0.24.
5. Total Cooldown Reduction is 24%, not 25%.
