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).
- bypasses this limit (up to 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 (ASbase) is calculated using a hidden variable called attack delay,[1] which ranges from −0.10 to 0.08. (ASbase) is the total number shown at level 1 without runes, masteries, etc. It is represented this way throughout the wiki.
$${\it AS}_{\rm base} = {0.625 \over 1 + {\it attack\ delay}}$$
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.
- Items
- Champion abilities
- Masteries
- Template:Rune runes
Bonus AS% stacks additively.
- Example: grants +50% attack speed and also grants +50% attack speed, so the champion gains +100% 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:
- attack delay is −0.04.
- \({0.625 \over (1 - 0.04)} = {0.625 \over 0.96} = 0.651041\overline6\). This is 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
- At level 18 he has gained \(3.22\% \times 17 = 54.74\%\) as bonus AS%.
levels up, he gains 3.22% as bonus AS%.
- At 18 he has maxed increasing his attack speed by 30%.
- Let's say he has the mastery up to 4%.
- Let's also say he has : +50%.
- All together he has: \(54.74\% + 30\% + 4\% + 50\% = 138.74\%\) bonus AS% or 1.3874 bonus AS as a decimal.
- Every time
- Final calculation:
- \(\begin{align} & {0.625 \over 0.96} + ({{0.625 \over 0.96} \times 139.74\%}) \\ =& 0.651041\overline6 + ({0.651041 \times 138.74\%}) \\ \approx & 1.55429 \end{align}\)
- In game, the number will be shown as: 1.554.
