Attack Speed
 
 
Focus Fire icon

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 agility, abilities providing flat bonuses and auras.

Mechanics[]

IAS vs BAT Attack per second graph

IAS vs BAT: attacks per second

Most heroes have a base attack speed and base attack time of 50 and 1.8 respectively.

Total attack speed is defined as

Σ Attack Speed = (Base Attack Speed + Σ Agility Current + Σ Flat Attack Speed Bonuses) × (1 + Attack Speed Multiplier), & 20 ≤ Σ Attack Speed ≤ 700

Attack speed bonuses and reductions stack additively by a flat value and/or percentages. By default, the total attack speed value has a minimum of 20 and an maximum value of 700 and most unit's attack speeds cannot be reduced or increased beyond the values above.

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

r = (Σ Attack Speed) / (100 × BAT)

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

T = 1 / r

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 agility and attack speed bonus.

For example, a Melee Creep Radiant icon Melee Creep has a BAT of 1, and thus attacks once per second by default. Similarly, if a hero with 1.8 BAT with no Agility attribute symbol 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 agility at level 1. What is Marci minimap icon Marci's current attack rate?
Marci minimap icon Marci attacks about 0.706 times per second in this example, and takes 1.416 seconds between attacks.

Benchmark[]

Most heroes' attack rate is 0.556 attacks per second. Attack speed is expressed in percent of base attack speed. The base is therefore expressed as 50. Each point of increased attack speed (IAS) sources add 0.5 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 50 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 1.8 BAT, the attack speed values in the HUD will be displayed as if they have 1.8 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 1.53, because 0.85 seconds is how long a unit with 1.8 BAT and 1.53 attack speed would take in between attacks.

This strange quirk makes it harder to figure out if a hero without the standard 1.8 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:

Most heroes have a BAT of 1.8 except for the following:

Base Attack Time Manipulation[]

Attack Speed Limits[]

Heroes with a unique base attack speed will also have a unique minimum attack speed equal to the difference between the hero's base attack speed and the default 50 base attack speed.

For example, Tiny minimap icon Tiny has a base attack speed of Lua error in Module:Show at line 24: attempt to index field '?' (a nil value)., which is Expression error: Unexpected < operator. less attack speed than the default 50. Therefore, his minimum attack speed will be Expression error: Unexpected < operator., which is Expression error: Unexpected < operator. less attack speed than the default 20 minimum attack speed.

This means despite Tiny minimap icon Tiny and Drow Ranger minimap icon Drow Ranger both having the same 1.8 BAT, their slowest attack rates are Expression error: Unexpected < operator. and 9 seconds respectively. This works in reverse for higher base attack speeds — Mirana minimap icon Mirana, whose base attack speed is Lua error in Module:Show at line 24: attempt to index field '?' (a nil value)., will have a minimum attack speed of Expression error: Unexpected < operator..

However, this minimum attack speed mechanic does not appear to apply to non-hero units. For example, Roshan icon Roshan and Hoodwink minimap icon Hoodwink, who both have 2 BAT, both have a minimum attack rate of 10 seconds, despite Roshan having a base attack speed of 200.

The maximum attack speed of all heroes is 700. This value does not change based on the heroes' base attack speed. This means that heroes like Tiny minimap icon Tiny have a greater attack speed range (Expression error: Unexpected < operator. – 700) , and heroes like Mirana minimap icon Mirana have a lesser attack speed range (Expression error: Unexpected < operator. – 700) than the average hero (20 – 700).

Maximum Attack Speed[]

The following abilities are able to change a unit's maximum attack speed (of 700), allowing it to reach even higher values. If a unit is affected by multiple abilities that change the maximum value, the higher value takes priority.

Maximum Attack Speed Changing Abilities
  • Moment of Courage icon
    Proc Chance: 25% (Talent 33%)
    Buff Attack Speed Bonus: 1000
    Duration: 1
