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 2.5 attacks per second (or 1 attack every two fifths of a second, or 0.4 seconds).

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 (ASbase) is calculated using a hidden variable called attack delay,[1] which ranges from −0.10 to 0.3. (ASbase) is the total number shown at level 1 without runes, masteries, etc. It is represented this way throughout the wiki.

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

Bonus attack speed sources

Bonus AS% stacks additively.

Example: Stinger item.png Stinger grants +35% attack speed and Nashor's Tooth item.png 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 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:
    • Twisted Fate Twisted Fate's attack delay is −0.04.
    • \pagecolor{Black}\color{White}{0.625 \over (1 - 0.04)} = {0.625 \over 0.96} = 0.651041 \overline{6}. This is Twisted Fate 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 Twisted Fate Twisted Fate levels up, he gains bonus AS% based on percentage growth 3.22% and his level through the statistics growth formula.
      • At level 18 he has gained \pagecolor{Black}\color{White}3.22\% \times\left({7 \over 400}\times(18^2-1)+{267\over400}\times(18-1)\right)=54.74\% as bonus AS%.
    • At 18 he has maxed Stacked Deck.png Stacked Deck increasing his attack speed by 30%.
    • Let's say he has the Fury mastery 2016.png Fury mastery up to 4%.
    • Let's also say he has Stinger item.png Stinger: +35%.
    • All together he has: 54.74% + 30% + 4% + 35% = 123.74% bonus AS% or 1.2374 bonus AS as a decimal.
  • Final calculation:
    \pagecolor{Black}\color{White}\begin{align} & {0.625 \over 0.96} + \left({{0.625 \over 0.96} \times 123.74\%}\right) \\ =& 0.651041\overline6 + ({0.651041 \times 123.74\%}) \\ \approx & 1.45664 \end{align}
    • In game, the number will be shown as: 1.457.
