Attack speed

Template:TOCright**Attack speed** (**AS** or **ASPD**) is a stat that is the frequency of a unit's basic attacks. They are measured and displayed as attacks per second.

Each champion starts with a certain **base** attack speed. Additional bonus **attack speed** can be obtained through level-up or with a variety of items, abilities and runes. Some champions can even start with bonus attack speed at level 1, however it does not count as bonus attack speed. Bonus **attack speed** stacks additively, and each bonus point acquired directly affects its statistic. **Bonus** attack speed is a percentage of the **base** attack speed, therefore, champions with higher base attack speed benefit more from bonus attack speed.

**Attack speed is capped at Template:Fd attacks per second** *(or 1 attack every Template:Fd seconds)*, but it can be removed with certain effects.

Template:Gold value​​​​

* **Attack speed** has a gold value of Template:G per point.

## Calculations

### Bonus attack speed per level

Champions gain an attack speed percentage every time they level up, which ranges from roughly **0 - 6%** (the exact number depending on the specific champion) and can be calculated through the statistics growth formula.

Bonus AS% stacks additively.

*Example: Template:Ii grants +35% attack speed and Template:Ii grants +50% attack speed, so the champion gains +85% in total.*
**Notes:**

* Final attack speed cannot go above the cap of **Template:Fd 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

* Template:Cis base attack speed is Template:Fd.
* Calculating "bonus attack speed":
	+ Every time **Lua error in Module:ImageLink at line 134: attempt to call field 'champion' (a nil value).** levels up, he gains bonus AS% based on his percentage growth Template:Fd% and his level through the statistics growth formula.

	+ Let's say he has maxed Template:Ai increasing his attack speed by 30%.
	+ He also has the Template:Ri rune to 3%.
	+ And he has Template:Ii: +35%.
	+ All together he has: Template:Fd% + 30% + 3% + 35% = Template:Fd% bonus AS% or Template:Fd bonus AS as a decimal.

	+ In game, the number will be shown as: Template:Fd.

## Removing or exceeding the attack speed cap

The following game elements can remove or exceed the Template:Fd-attacks per second cap, potentially allowing infinite amounts of attacks per second or giving a fixed attack speed above the cap respectively.

### Removing the cap

#### Runes

* Template:Ri
* Template:Ri

### Fixed attack speed above the cap

#### Champions

* Template:Cai - This has a fixed attack speed of 3.0, which cannot be affected by bonuses.

## 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.

### Champions

* Template:Cai and Template:Ai
* Template:Cai
* Template:Cai
* Template:Cai

## Decreasing attack speed

Main article: Types of Crowd Control § Cripple
Attack speed reductions stack multiplicatively and take percentages off the final attack speed value after all bonus attack speed has been factored in. Attack speed reductions are affected by Tenacity, but not by Slow resist.

## Capped attack speed

The majority of champions are capped at Template:Fd attacks per second. But some champion abilities make it impossible to reach that cap:

* Template:Cai
* Template:Cai
* Template:Cai

## 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 Template:Cai).
