In League of Legends, speed often equals power. For champions who rely on basic attacks—like Jinx, Master Yi, or Vayne—attack speed is a defining stat. It determines how often a champion can land auto attacks, which in turn affects their damage output, objective control, and overall presence in fights.
But even in a game known for its complex scaling and item synergies, there are limits. So, what exactly is the maximum attack speed in League of Legends, and how do players reach it?
The Base Cap: 2.5 Attacks Per Second
According to Riot Games’ official mechanics, the base maximum attack speed a champion can reach is 2.5 attacks per second. This cap applies to most sources of attack speed and ensures a fundamental level of balance across the roster of over 160 champions.
How Players Reach (and Exceed) the Cap
Getting to 2.5 attacks per second and potentially exceeding it requires a strategic combination of runes, items, and abilities, often tailored to specific champions. Here’s how players typically approach it:
- Items: Core items like Kraken Slayer, Guinsoo’s Rageblade, Wit’s End, and Runaan’s Hurricane all provide significant attack speed bonuses.
- Runes: The Precision keystone Lethal Tempo is unique in that it allows eligible champions to temporarily exceed the 2.5 attack speed cap when fully stacked.
- Abilities: Champions like Kayle, Master Yi, or Kog’Maw have built-in abilities that temporarily increase attack speed or reduce the time between auto attacks.
- Buffs: External boosts from allied champions (e.g., Lulu’s Help, Pix! with Whimsy, or Janna’s Eye of the Storm) can further push players toward the base cap.
While champions can technically build more attack speed than the base cap, any value beyond 2.5 attacks per second is wasted unless they have effects like Lethal Tempo allowing them to surpass it, or it interacts with another mechanic (like applying on-hit effects more frequently before a temporary buff ends).

Who Reaches It—and Why It Matters
Reaching or exceeding the attack speed cap is most common on marksmen (ADC) and on-hit fighters, where consistent auto-attacking is central to the champion’s role. Champions like:
- Master Yi, who benefits from attack speed during Wuju Style and Highlander and can leverage Lethal Tempo.
- Vayne, whose Silver Bolts synergize with rapid attacks, making high attack speed valuable, potentially exceeding the cap with Lethal Tempo.
- Jinx, who relies on attack speed to trigger her passive and shred towers, also benefiting greatly from Lethal Tempo.
Does Anything Bypass the Cap?
While the base attack speed cap is 2.5 attacks per second, there is one significant exception: the Lethal Tempo rune. When fully stacked, Lethal Tempo allows eligible champions to temporarily exceed the 2.5 attacks per second cap, increasing their actual attack speed beyond this limit.
Other effects don’t bypass the actual attack frequency cap but can interact with high attack speed in beneficial ways:
- Champion passives like Yasuo and Yone’s double-hit mechanics leverage high attack speed to deliver damage more frequently, even within cap limits or when exceeding them.
- Item procs and on-hit abilities are triggered by basic attacks, so reaching or exceeding the attack speed cap means these effects are applied more often, significantly increasing overall damage per second.
A Matter of Balance
The base 2.5 cap, and the limited ways to exceed it, exist to preserve gameplay balance. Without such limits or controlled exceptions, hyper-carry champions could scale into unstoppable forces, overwhelming opponents with a hail of auto attacks before they could even react. Riot has fine-tuned the system to reward smart itemization while preventing excessive snowballing, allowing specific runes like Lethal Tempo to offer unique power spikes within carefully designed boundaries.
Final Thoughts
The base maximum attack speed in League of Legends may be capped at 2.5 attacks per second for most effects, but the ability of Lethal Tempo to break this limit adds a crucial layer to understanding fast-paced combat. Whether you’re an ADC looking to optimize your build or a support planning to boost your carry, understanding how attack speed works—and when it can exceed its usual limits—is crucial to dominating the Rift.
And while the cap isn’t entirely unbreakable for certain runes, the thrill of pushing right up against (or temporarily past) it remains one of the most satisfying power spikes in the game.
