Attack speed

Attack speed is a champion statistic that indicates the number of basic attacks a champion can output.

Additional bonus attack speed can be obtained through level-up or with a variety of items, abilities and runes. Bonus attack speed 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.

Attack speed cap alteration
The maximum amount of attack speed a champion can have, 2.5, can be exceeded or altered by abilities or game mechanics.
