Attack Speed

Attack speed is the League of Legends stat that determines how many basic attacks a champion can perform per second. Higher attack speed means more autos in the same window, which directly multiplies sustained damage and on-hit effects.

It is a cornerstone stat for marksmen and on-hit fighters, pairing naturally with AD, critical strike, and lifesteal. Attack speed has a hard cap of 2.5 attacks per second, so beyond a point further stacking is wasted. Many champions also gain bonus attack speed by leveling their abilities, on top of what items provide.
