Attack speed

 Attack speed, or AS, is a stat that denotes the rate of a unit's basic attack, measured in attacks per second.

Every champion starts with a certain attack speed ratio, which for most champions is equal to their assigned base attack speed (attack speed at level 1 without any other bonuses), while some other champions can start with a modified base attack speed (different from their attack speed ratio — the modifier is handled as a bonus). Total attack speed refers to base plus bonus attack speed. Bonus attack speed is a percentage of the attack speed ratio, therefore champions with a higher ratio benefit more from bonus attack speed.

Attack speed is handled differently than other stats in terms of scaling. A champion's base attack speed is fixed at its unmodified level 1 value. Instead, every increase is considered a bonus, including the growth per level. Other than levels, bonus attack speed can also be gained from any source such as abilities, buffs, items, runes, and others.

• Bonus attack speed stacks additively, and each percent point acquired directly adds to the statistic (1:1).

Attack speed is capped at 2.5 attacks per second (1 attack every 0.4 seconds). It also cannot be reduced below a floor of 0.2 (1 attack every 5 seconds). A select few effects can modify the attack speed cap.

Gold Value ​​​​​​

• Bonus attack speed has a gold value of 25 per percent point.

Calculations

Bonus attack speed per level

Excluding the outlier of Bel'Veth (who does not gain any attack speed per level due to her innate), attack speed growth coefficients range from 0.5% to 6%, varying by champion. Total attack speed can be calculated through a slightly modified statistics growth formula, but the growth formula for attack speed is still the same (meaning, attack speed growth happens at the same rate as any other statistic's growth).

Decimals are almost unavoidable with attack speed, so note that the tooltip values displayed in-game may be rounded and slightly different; in the HUD, the displayed attack speed itself rounds to 2 decimals, while the tooltip rounds values to a fairly good precision of 3 decimals.

Example

• Twisted Fate's base attack speed is 0.625 and his attack speed ratio is 0.651.
• Calculating "bonus attack speed":
  • Every time Twisted Fate levels up, he gains bonus AS% based on his percentage growth 2.5% and his level through the statistics growth formula.
    • At level 10 he has gained 2.5% × 9 × (0.7025 + 0.0175 × 9) = 19.35% as bonus AS%.
  • Suppose Stacked Deck is at rank 5, increasing his attack speed by 50%.
  • The Legend: Alacrity rune is giving 3% attack speed.
  • And he has Berserker's Greaves: +25%.
  • All together he has: 19.35% + 50% + 25% + 3% = 97.35% bonus AS%.
• Final calculation: With this champion, base attack speed and attack speed ratio are different. Therefore, we need to use the longer formula which takes both into account:

  0.625 + (0.651 ×  97.35 ÷ 100)
  ≈ 1,2587485

  • In game, the number will be shown as: 1,259.

Short formula

For practical purposes, a shorter formula from the generalized attack speed formula is used in order to calculate attack speed; the "bonus" factor is also always known from the in-game tooltips.

Bonus attack speed is a percentage that represents how much of a unit's attack speed ratio is added on top of their base attack speed. In other words, some scaled multiple of the attack speed ratio is added to the base attack speed, to calculate the unit's total attack speed.

Simple example

Suppose that we have a unit with a base attack speed of $\color{black}{0.7}$ and an attack speed ratio of $\color{black}{0.7}$.

If this unit has 100% bonus attack speed from some number of sources, then the bonus attack speed multiplier is $\color{black}{1.0}$, resulting in a value modified by the attack ratio of $\color{black}{1.0}\times{0.7} = {0.7}$. Then we add this result to their base attack speed to get the total of $\color{black}{1.4}$ attack speed (1.4 attacks per second). The full calculation is:$\color{black}{0.7 + 1.0\times0.7 = 1.4}$

Suppose that same unit had 50% bonus attack speed instead. That means the bonus attack speed multiplier is $\color{black}{0.5}$, resulting in a value modified by the attack ratio of $\color{black}{0.5}\times{0.7} = {0.35}$. Then we add this result to their base attack speed to get the total of $\color{black}{1.05}$ attack speed (1.05 attacks per second).

At 200% bonus attack speed, that unit will have 2.1 total attack speed.

At 10% bonus attack speed, that unit will have 0.77 total attack speed.

Generalization

Let:

• $\color{black}{\rm b}$ be the unit's base attack speed
• $\color{black}{\rm m}$ be the unit's attack speed ratio
• $\color{black}{\rm x}$ be the sum of all attack speed bonuses on the unit
• $\color{black}{\rm y}$ be the unit's total attack speed

Then the total attack speed is calculated through the equation $\color{black}{\rm y = mx+b}$ which is a linear equation of attack speed in terms of its bonuses.

Most champions' base attack speed and attack speed ratio are equal, meaning $\color{black}{\rm m}$ can be replaced with $\color{black}{\rm b}$, resulting in the equation  $\color{black}{\rm y = bx+b}$ or simply $\color{black}{\rm y = b(x+1)}$

Exceeding or altering the attack speed cap

The following game elements will modify the 2.5-attacks-per-second cap:

Removing the cap

Effects that remove the attack speed cap allow characters to fire basic attacks at rates higher than 2.5, given high enough attack speed bonuses. The cap is technically increased to 90.0 for the duration, however limits to the game itself only allow for up to 30 attacks per second, or one per frame. Bel'Veth is the only champion in the game that can exceed the attack speed cap by default.

Champions

• Bel'Veth's Death in Lavender - Increases the attack speed cap to 9999.0
• Jinx's Get Excited!
• Kennen's Lightning Rush
• Varus' Living Vengeance - Increases the attack speed cap to 2.7632.

Runes

• Hail of Blades

Fixed attack speed above the cap

Champions

• Urgot's Purge - This has a fixed rate of 3.0 per second of automatically fired missiles that apply attack effects. It does not interact with bonuses nor the attack speed stat itself.

Reducing the cap

Champions

• New Destiny - Special attack cooldown and attack speed calculation; Graves cannot reach 2.5 attack speed.
• Whisper - Jhin's attack speed does not benefit from any bonuses other than its growth; Jhin cannot reach 2.5 attack speed.
• Sion's Glory in Death effectively reduces his attack speed cap to 1.75 and increases his attack speed floor to 1.75 until the ability ends. Other modifiers are still allowed to alter the cap.
• Zeri's Burst Fire reduces her attack speed cap to 1.5, attack speed from Lightning Crash can exceed this cap.

Attack speed as scaling

The major part of champion abilities that use attack speed will scale with base attack speed. But some abilities scale with the total or bonus attack speed the champion has.

Note that any (bonus) attack speed exceeding the attack speed cap will still improve these ability scalings, as they are not depending on the absolute attack speed stat.

Notes

• All percentages listed in a champion's attack speed statistic are approximations.
• Many abilities can scale indirectly with attack speed (for example, through the flat cooldown reduction per attack with Master Yi's Alpha Strike).

Trivia

• The old stat icon for attack speed was an edited red recolor of the icon of Stinger.
