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 2.5 attacks per second (or 1 attack every 0.4 seconds), but it can be removed with certain effects.

Gold Value ​​​​

  • Attack speed has a gold value of Gold 25 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: Stinger item Stinger grants +35% attack speed and Nashor's Tooth item Nashor's Tooth grants +50% attack speed, so the champion gains +85% in total.

Notes:

  • Final attack speed cannot go above the cap of 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

  • Twisted Fate OriginalSquare Twisted Fate's base attack speed is 0.651.
  • Calculating "bonus attack speed":
    • Every time Twisted Fate OriginalSquare Twisted Fate levels up, he gains bonus AS% based on his percentage growth 3.22% and his level through the statistics growth formula.
      • At level 10 he has gained $ \pagecolor{Black}\color{White}3.22\%\times(10-1)\times(0.7025+0.0175\times(10-1))=24.9228\% $ as bonus AS%.
    • Let's say he has maxed Stacked Deck Stacked Deck increasing his attack speed by 30%.
    • He also has the Legend- Alacrity rune Legend: Alacrity rune to 3%.
    • And he has Stinger item Stinger: +35%.
    • All together he has: 24.9228% + 30% + 3% + 35% = 92.9228% bonus AS% or 0.929228 bonus AS as a decimal.
  • Final calculation:
    $ \pagecolor{Black}\color{White}\begin{align} & 0.651 \times (1 + 0.929228) \\ \approx & 1.255927 \end{align} $
    • In game, the number will be shown as: 1.256.

Removing or exceeding the attack speed cap

The following game elements can remove or exceed the 2.5-attacks per second cap, potentially allowing infinite amounts of attacks per second or giving a fixed attack speed above the cap respectively.

  • Urgot OriginalSquare Urgot's Purge Purge - 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.

Decreasing attack speed

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.
