A cooldown is a period of wait time before a spell, ability, or item power can be used again.

Mechanics[]

Usually, an ability will be on cooldown if the ability was activated and the cast time of the ability has passed. If the hero is interrupted before the channel time is over, the ability does nothing, and the cooldown and mana is wasted. On the other hand, abilities like Assassinate and Requiem of Souls have long cast times, and they will not go on cooldown before the cast time is over. Charge of Darkness is an exception to the usual rule; it goes on cooldown once the charge ends or is canceled, not upon cast.

If a hero has several versions of the same item, all versions will be on cooldown upon activating one of them. For instance, all Dagon 1 icon.png Dagons are in the same cooldown group.

Some abilities or items have multiple cooldowns, using a different cooldown duration if their conditions are met. For instance, Culling Blade's cooldown is 0, but only when successfully killing a hero.

Many abilities have reduced cooldown when leveled up. If an ability is on cooldown and it is leveled up, the current wait time will not be affected at all.

Some abilities have charges and a charge replenish time instead of the usual cooldown. For instance, Shrapnel has 3 (Talent 9) charges and a 35 (Talent ) second replenish time for each charge.

Cooldown Manipulation[]

Some abilities and items are able to manipulate the cooldowns of abilities. There are several different types of cooldown manipulation:

Percentage-based Reductions and Increases

These cooldown modifiers reduce or increase the cooldowns of all abilities and items by a percentage when used. They cause abilities and items to enter a reduced or increased cooldown after being acquired. This means they do not retroactively affect already running cooldowns. Percentage-based cooldown reductions do not stack, the highest value takes priority.

Flat Reduction and Increases

These cooldown modifiers reduce or increase the cooldowns by flat amounts. Unlike percentage-based cooldown modifiers, these can affect abilities which are already on cooldown. Flat changes are applied before percentage-based changes.

Cooldown Resetting

Some abilities are able to completely reset the cooldowns of abilities and items instantly, so that they are ready to use again.

Talents[]

The following heroes have Talent talents which reduce cooldowns of specific abilities by a flat amount:

Other Interactions[]

Unaffected by Cooldown Manipulation[]

The following abilities have cooldowns that are unaffected by cooldown manipulation for several reasons:

  • The ability may use a custom cooldown system, which is not covered by default cooldown manipulation.
  • The ability may use a cooldown for other purposes, for example, to indicate a delay before taking effect, like the effect delay of invisibility.
  • Abyssal Blade icon.png
    Cooldown: 2.3
    Unlike Skull Basher icon.png Skull Basher, Abyssal Blade's bash uses a custom cooldown system, because a regular cooldown would prevent the player from using the item's active ability.

Charges[]

Some abilities use the charge mechanic, instead of cooldowns. These abilities have a set number of charges on them, which replenish over time. Instead of going on cooldown, these abilities use up one charge per cast. This means when having multiple charges, they can be cast quickly in succession, but cannot be used when having no charges left. Each charge takes a certain time to replenish. Multiple charges of a spell do not replenish at the same time, they recharge one after another.

Charge-based abilities will appear to be on cooldown when using the last charge. This "cooldown" however is only to visualise when the next charge is going to be ready again.

The replenish time of charges can be affected by the cooldown reductions of Octarine Core icon.png Octarine Core, Arcane Rune minimap icon.png Arcane Rune, and talents, and can all be replenished with Refresher Orb icon.png Refresher Orb, and are also affected by Chakra Magic and Time Dilation. Other sources of cooldown manipulation cannot grant charges back or affect the recharge times.

An ability's current charges and recharge time are indicated by a number at the bottom left corner of the ability icon, surrounded by a green circle that fills up while recharging a charge.

Charge-based Abilities[]

The following abilities use the charge system:
