攻击速度

Attack speed (often shortened as AS or ASPD) is the frequency at which a champion performs basic attacks and are displayed as "attacks per second". Attack speed caps at 2.5 attacks per second, or 1 attack every two fifths of a second.

Attack speed bonuses works by adding a percentage of a champion's base attack speed to his or her "base attack speed." Champions with a low base attack speed will receive less of an attack speed boost from the bonus than champions with a high base attack speed, but the proportional increase in DPS will remain the same for both. One's attack speed can be increased via leveling up, items, runes, masteries, buffs, and abilities. One's attack speed can only be decreased by items, abilities, and the Dragon.

Calculations

Base attack speed

Every champion's "base attack speed" (AS_base) is calculated using a hidden variable called "attack delay." Attack delay is a number between −0.10 and 0.08:

AS_base = 0.625 / (1 + attack delay)

This value is the total number shown at level 1 without runes, masteries, etc. It is represented this way throughout the wiki.

The bonus AS% can come from 6 sources:

• Champions gain AS% at each level, not including level 1. This amount ranges from roughly 1% to 4% and depends on the champion.
• Items
• Champion abilities
• The Alacrity Alacrity mastery
• Alacrity runes
• The Crest of Nature's Fury buff

Bonus AS% stacks additively.

Example: Madred's Bloodrazor grants +40% attack speed and Malady grants +50% attack speed, so the champion gains +90% 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.

Calculation example

• Calculating "base attack speed":
  • Twisted Fate's attack delay = −0.04.
  • 0.625 / (1 − 0.04) = 0.625 / 0.96 = 0.6510416. This is 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 levels up, he gains 3.22% as bonus AS%.
    • At level 18 he has gained 3.22% × 17 = 54.74% as bonus AS%.
  • At 18 he has maxed Stacked Deck increasing his attack speed by 15%.
  • Let's say he has the Alacrity Alacrity mastery up to 4%.
  • Let's also say he has Phantom Dancer: +55%.
  • All together he has: 54.74 + 15 + 4 + 55 = 128.74% as bonus AS%.
• Final calculation:
  • (0.625 / 0.96) × (100% + 128.74%).
  • 0.6510416 × 228.74% = 1.48919271.
  • In game, the rounded number will be shown as: 1.489.
