Cooldown (abbreviated CD) is a property of hero abilities, passives, equipment, battle spells, and emblems.
It is the period of time during which an ability, passive, equipment, battle spell or talent associated with it must be waited before ready to be used again.
Skill cooldown is affected (quickened, skipped) by cooldown reduction, cooldown speed while battle spell cooldown is affected by battle spell Cooldown reduction.
The cooldown for abilities, items and passives are unaffected during the time when a hero dies.
Charge-based abilities[]
Some heroes have abilities that have charges, which means the ability can be used multiple times in quick succession to be more effective, each time is considered a separate skill cast and reduces a charge and only unusable when running out of charge. Each charge will replenish at the cooldown time and is fully affected by cooldown reduction and cooldown speed.
- Therefore, charge-based abilities fully benefit from
War Cry, better than abilities with multicast.
Charge-based abilities start with 0 charges and begin to replenish when the ability is first learnt.
Though a charge-based ability can be cast in quick succession, there is still a slight cooldown between each charge cast to prevent it from being overpowered.
- eg.
Badang's 
Fist Wind.
When 
Valentina copies a charge-based ability, the ability also begins with 0 charges, begins to recharge with Valentina with the recharge time of the stolen hero.
Cooldown reduction and Cooldown speed does not affect the recharge time, but they do affect the cooldown between each charge cast.
