Ability Haste

Ability Haste is the stat which reduces the Cooldown of Abilities in Predecessor. Each point of Ability Haste reduces the Cooldown by a varying amount, following this equation. Every Ability in Predecessor is affected by Ability Haste, however Crest active Abilities (including most passives), Blink, and Ward/Sentry usage is not.

The percentage that your ability cooldowns are reduced by can be calculated using the formula:

Cooldown Reduction % = 100 * Ability Haste/(100 + Ability Haste)

Ability Haste has diminishing returns past 50% Cooldown Reduction.
