Attack Speed ( ) is the frequency with which units attack is measured. A unit's attack speed can be modified by items, per point of Agility attribute symbol.png agility, abilities providing flat bonuses and auras.

Mechanics[]

IAS vs BAT: attacks per second

Most heroes have a base attack speed and base attack time of 100 and 1.7 respectively.

Total attack speed is defined as

With ASbase being the base attack speed, ai and ri being the flat additive and flat reduction bonuses.

Attack speed bonuses and reductions stack additively by a flat value. Unlike movement speed, there is currently no sources that reduces attack speed by a percentage. The total attack speed value has a minimum of 20 and an maximum value of 700 and a unit's attack speed cannot be reduced or increased beyond the the values above.

The attack rate is the amount of attacks a unit can launch within a second, and is defined as

With Ar being the amount of attacks per second (Attack Rate), ASB being the hero's base attack speed and BAT being the base attack time.

Therefore, the time needed per attack a hero launches is defined as

Base Attack Time[]

Every unit has a base attack time (BAT), which refers to the default interval between attacks for a unit without considering Agility attribute symbol.png agility and attack speed bonus.

For example, a Melee Creep Radiant icon.png Melee Creep has a BAT of 1, and thus attacks once per second by default. Similarly, if a hero with 1.7 BAT with no Agility attribute symbol.png agility and no bonus attack speed, they would attack once every 1.7 seconds. While nearly every unit can have their attack speed modified, only a few heroes can actively change their BAT.

Examples[]

With a base attack time of 1.7, 100 base attack speed and 20 Agility attribute symbol.png agility at level 1. What is Marci minimap icon.png Marci's current attack rate?
Marci minimap icon.png Marci attacks about 0.706 times per second in this example, and takes 1.416 seconds between attacks.

Benchmark[]

Most heroes' attack rate is 0.588 attacks per second. Attack speed is expressed in percent of base attack speed. The base is therefore expressed as 100. Each point of increased attack speed (IAS) sources add 1 point to it, and attack speed works together with base attack time to determine how often a unit can attack.

When hovering over the hero's attributes in the HUD, the first field shows the attack speed and the time required per attack in parenthesis. The attack speed field is defaulted to 100 and adds the attack speed bonuses or reductions afterwards, leading to a minimum of 20 and a maximum value of 700.

Even though the HUD may show a unit to exceed these boundaries, the actual attack speed used for calculations will still obey the minimum and maximum values.

For units that do not have 1.7 BAT, the attack speed values in the HUD will be displayed as if they have 1.7 BAT. For example, a unit with 0.85 BAT and no other attack speed bonus sources will display itself as having an attack speed of 1.445, because 0.85 seconds is how long a unit with 1.7 BAT and 1.445 attack speed would take in between attacks.

This strange quirk makes it harder to figure out if a hero without the standard 1.7 BAT is nearing maximum attack speed, but it does allow players to compare this uniform metric across all heroes easier.

The following table shows the attack speed benchmarks and their effect on attacks per second:
