Attack speed

**Attack speed** (often shortened as **AS** or **ASPD**) is the frequency of a champion's basic attacks. They are measured and displayed as attacks per second.

* **Attack speed cannot be increased beyond {{#vardefine:n|2.5}}2.5 attacks per second** *(or 1 attack every two fifths of a second, or {{#vardefine:n|0.4}}0.4 seconds)*.
	+ ไฟล์:Kog'MawSquare.png Kog'Maw's Bio-Arcane Barrage Bio-Arcane Barrage bypasses this limit (up to {{#vardefine:n|5.00}}5.00 attack per second).

Attack speed bonuses (from items or abilities, etc.) are in **percent**. The bonus is a percentage of the champions base attack speed. Therefore, champions with higher base attack speed benefit more from attack speed increases. Like all stats, one's attack speed can be increased via leveling up, items, runes, masteries, buffs, and abilities. Some items and abilities (only those two) decrease enemy attack speed.

## Calculations

### Base attack speed

Every champion's base attack speed (*AS*base) is calculated using a hidden variable called *attack delay,* which ranges from −{{#vardefine:n|0.10}}0.10 to {{#vardefine:n|0.08}}0.08. (*AS*base) is the total number shown at level 1 without runes, masteries, etc. It is represented this way throughout the wiki.

{\displaystyle \pagecolor{Black}\color{White}{\it AS}\_{\rm base} = {0.625 \over 1 + {\it attack\ delay}}}

### Bonus attack speed sources

* Champions gain AS% at each level, not including level 1. This amount ranges from roughly **0% to 4%** and depends on the champion. This amount depends on the level through the *Statistics* growth formula.
* Items
* Champion abilities
* Masteries
* Attack Speed runes

Bonus AS% stacks additively.

*Example: Stinger Stinger grants +35% attack speed and Nashor's Tooth Nashor's Tooth also grants +50% attack speed, so the champion gains +85% in total.*
**Notes:**

* Final attack speed cannot go above the cap of **{{#vardefine:n|2.5}}2.5 attacks per second**.
* Many in-game tooltip percentages (such as runes) have been rounded, so results may be slightly different unless the precise numbers are known.

### Example

* Calculating base attack speed:
	+ ไฟล์:Twisted FateSquare.png Twisted Fate's attack delay is −0.04.
	+ 0.625

	(

	{\displaystyle \pagecolor{Black}\color{White}{0.625 \over (1 - 0.04)} = {0.625 \over 0.96} = 0.651041 \overline{6}}

	. This is ไฟล์:Twisted FateSquare.png Twisted Fate's base attack speed, seen at level 1 (without runes, masteries, etc.).
	+ The number seen in game is rounded to 3 decimal places: 0.651.
* Calculating "bonus attack speed":
	+ Every time ไฟล์:Twisted FateSquare.png Twisted Fate levels up, he gains bonus AS% based on percentage growth 3.22% and his level through the Statistics growth formula.

		 as bonus AS%.
	+ At 18 he has maxed Stacked Deck Stacked Deck increasing his attack speed by 30%.
	+ Let's say he has the Fury Fury mastery up to 4%.
	+ Let's also say he has Stinger Stinger: +35%.
	+ All together he has: 54.74% + 30% + 4% + 35% = 123.74% bonus AS% or {{#vardefine:n|1.2374}}1.2374 bonus AS as a decimal.
