Attack speed in LoL: the 3.003 cap and how much DPS it gives
Attack speed is the stat that multiplies everything: more autos per second is more damage, more on-hit and more chances to crit. But it has a hard ceiling at 3.003, and going past it wastes gold. Here you see exactly how much it returns and where it stops.
What it is: base, bonus and the 3.003 cap
Attack speed is measured in attacks per second. Each champion has a base (marksmen start higher) that grows a little per level, and items and runes give bonus as a percentage. That percentage applies to your base speed, so the same 40% returns more on a champion with a high base.
The key point: there’s a hard cap of 3.003 attacks per second (one auto every 0.33 s). Once you hit it, each extra point of attack speed does absolutely nothing. The chart shows it with the real engine: DPS rises in a straight line… until the elbow, where the line flattens abruptly. Buying attack speed past that point is wasted gold.
That’s why marksman builds don’t stack infinite attack speed: they mix it with attack damage, crit or on-hit so each hit lands harder, instead of trying to throw more hits than the cap allows.
velocidad de ataque = AS_base + AS_base × bonus% (tope: 3.003) DPS de auto = daño por golpe × velocidad de ataque Auto-attack DPS (Caitlyn level 18, no crit) adding attack speed, with the real engine. It rises in a straight line… until attack speed hits the 3.003 attacks/sec cap (raised from 2.5 in 2025): past that, each extra point does nothing. That’s why you mix in AD, crit or on-hit before going over the cap.
Why it multiplies everything: autos, on-hit and crit
Attack speed doesn’t raise the damage of one hit; it raises how many hits you land. Since your DPS is damage-per-hit × attack speed, doubling attack speed doubles your auto DPS — as long as you don’t hit the cap.
And it multiplies more than base damage: each extra auto also applies your on-hit damage (Nashor’s Tooth, poisons, magic-on-attack) and gives you another crit roll. That’s why attack speed is the natural partner of crit and on-hit: more hits = more procs of everything. We cover it in the crit guide.
The flip side: standing still attacking, attack speed is pure gold; but in real fights you lose autos moving and repositioning. That’s why movement speed and range matter so much: they let you turn that attack speed into actual hits.
When it pays off and when it stalls
Attack speed pays off early: you go from little to a lot in percentage, and since it multiplies, the first items feel huge. It pays less as you approach the 3.003 cap, down to nothing past it.
Rule of thumb for a marksman: build attack speed until you have a good hit rhythm, then add damage per hit (AD, crit, penetration) or on-hit. If your build already grazes the cap, the next attack-speed item is nearly wasted: swap it for something that multiplies differently.
Test your real build — champion, level, items — in the Build Lab to see your exact attack speed and DPS, and compare two paths hit by hit in Versus. And check the gold efficiency of each attack-speed item before stacking them.
FAQ
What is the attack speed cap in LoL?
The cap is 3.003 attacks per second for almost all champions (Riot raised it from the old 2.5 in early 2025). Once you reach it, extra attack speed does nothing (barring special cases that reconvert it). That’s why you stop buying it near the cap and switch to damage per hit.
Does attack speed increase ability damage?
Not directly: attack speed multiplies your auto-attacks and on-hit damage. Some abilities reset or use autos (Jinx, Kai’Sa, etc.) and benefit indirectly, but a spell’s own damage doesn’t scale with attack speed.
Why does the same attack speed % differ per champion?
Because the bonus% multiplies the BASE attack speed, which varies by champion. 50% on a 0.7 base adds more attacks than on a 0.6 base. That’s why marksmen, with high bases, get more out of attack-speed items.
