Attack speed icon.png 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 attack speed ratio, which is also the value given by default to their base attack speed (attack speed at level 1 without any other bonuses). Some champions can start with a base attack speed different from their attack speed ratio. Additional bonus attack speed can be obtained through level-up or with a variety of items, abilities and runes. Bonus attack speed Additive stacking icon.png stacks additively, and each bonus point acquired directly affects its statistic. Bonus attack speed is a percentage of the attack speed ratio, therefore, champions with higher ratio benefit more from bonus attack speed.

Attack speed is capped at 2.5 attacks per second (or 1 attack every 0.4 seconds). It also cannot be reduced below a floor of 0.2 (or 1 attack every 5 seconds). The values of these restrictions can be altered by certain effects.

Gold Value ​​​​​​

  • Attack speed has a gold value of 25 Gold 25 per point.

Calculations

Bonus attack speed per level

Champions gain bonus attack speed % 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 Stinger grants +35% attack speed and Nashor's Tooth 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, unless it is ignored by some effects.
  • 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's Twisted Fate's base attack speed and attack speed ratio are both 0.651.
  • Calculating "bonus attack speed":
    • Every time Twisted Fate 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 3.22% × 9 × (0.7025 + 0.0175 × 9) = 24.9228% as bonus AS%.
    • Let's say he has maxed Stacked Deck Stacked Deck increasing his attack speed by 40%.
    • He also has the Legend: Alacrity Legend: Alacrity rune to 3%.
    • And he has Stinger Stinger: +35%.
    • All together he has: 24.9228% + 40% + 3% + 35% = 102.9228% bonus AS%.
  • Final calculation:
    0.651 × (1 + 102.9228 ÷ 100)
    ≈ 1.321027428
    • In game, the number will be shown as: 1.321.

Exceeding or altering the attack speed cap

The following game elements will exceed or alter the 2.5-attacks-per-second cap:

Removing the cap

Effects that remove the attack speed cap allow characters to fire basic attacks at rates higher than 2.5, given high enough attack speed bonuses. The cap is technically increased to 90.0 for the duration, however limits to the game itself only allow for up to 30 attacks per second, or one per frame.

Champions

Runes

Fixed attack speed above the cap

Champions

  • Urgot's Urgot's Purge Purge - This has a fixed attack speed of 3.0. It does not interact with bonuses nor the attack speed stat itself.

Reducing the cap

Champions

  • Graves' Graves' New Destiny New Destiny - Special attack cooldown and attack speed calculation - cannot reach 2.5 attack speed.
  • Jhin's Jhin's Whisper Whisper - Always fixed to his base attack speed + innate attack speed growth, thus can never reach 2.5 attack speed.
  • Sion's Sion's Glory in Death Glory in Death - Reduces the cap to 1.75 and increases the floor to 1.75 until the effect ends. Effects that remove the attack speed cap (see above) still allow exceeding the cap.

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.

Note that any (bonus) attack speed exceeding the attack speed cap will still improve these ability scalings, as they are not depending on the absolute attack speed stat.
