Understanding Attack Speed

What is Attack Speed?

Attack speed (AS) is a stat that determines how frequently your character performs basic attacks or auto-attacks. It's expressed as attacks per second and directly influences your damage output, especially for builds that rely on consistent hits rather than burst damage.

Formula

Final Attack Speed = Base Attack Speed × (1 + Attack Speed Bonus %)

Example: 1.0 base AS with 50% bonus = 1.0 × 1.5 = 1.5 attacks per second

Base Attack Speed

Your starting attack speed determined by your character/class and weapon type. Different weapons have different base values (daggers are faster, axes are slower).

Attack Speed Bonus

The cumulative percentage increase from items, buffs, passives, and runes. This is added together before being applied to your base attack speed.

When to Build Attack Speed

✓ Build Attack Speed When:
  • Your champion/character scales with auto-attacks
  • You have on-hit effects or attack modifiers
  • You need lifesteal or sustain through attacks
  • Playing ADC, marksman, or auto-attack carry
  • Your abilities reset or enhance basic attacks
✗ Avoid Attack Speed When:
  • Your damage comes primarily from abilities
  • You're playing a burst assassin or mage
  • You lack base damage or crit chance
  • You're a tank focused on utility/CC
  • Already at or near the attack speed cap

Attack Speed Caps

Most games implement attack speed caps to prevent extreme values from breaking game balance. Understanding these caps helps you avoid wasting stats.

League of Legends
Hard cap at 2.5 APS
2.5 Max
Dota 2
Hard cap around 700 AS (varies)
~6.0 Max
Path of Exile
No hard cap, diminishing returns
Unlimited
Diablo IV
Soft cap with diminishing returns
Variable

Optimization Strategies

⚔️

On-Hit Builds

Maximize attack speed when your damage comes from effects that trigger on each hit, like Blade of the Ruined King, Wit's End, or Kraken Slayer.

  • Target 2.0+ attack speed for maximum procs
  • Balance with lifesteal for sustain
  • Don't neglect armor penetration
💥

Crit Builds

For crit-focused builds, attack speed amplifies your crit frequency. Balance AS with crit chance and crit damage for optimal DPS.

  • Aim for 1.5-2.0 attack speed sweet spot
  • Prioritize crit chance to 60% first
  • Add AS after core crit items
🛡️

Tanky DPS

Juggernauts and bruisers benefit from moderate attack speed paired with defensive stats and sustain. Quality over quantity.

  • 1.0-1.5 attack speed is usually sufficient
  • Focus on base damage and survivability
  • Use AS for sticking to targets

Ability Synergy

Some abilities scale with or reset from auto-attacks. Attack speed directly increases your ability uptime and combo potential.

  • Examples: Jax, Irelia, Master Yi
  • Faster autos = more ability procs
  • Stack AS for maximum uptime

Balancing Stats

The DPS Trinity

For maximum damage output, you need to balance three core stats. Focusing on just one creates inefficiency.

⚔️
Attack Damage

Your base damage per hit. Without sufficient AD, attack speed just hits faster for less.

Attack Speed

How often you deal damage. Amplifies your AD and enables on-hit effects to proc more.

💥
Critical Strike

Multiplies your damage through RNG. Works with both AD and AS to create burst potential.

💡 OPTIMIZATION RULE

A balanced build with 70% efficiency in each stat outperforms a build with 100% in one stat and neglecting the others. Aim for equilibrium, not extremes.

Common Mistakes to Avoid

Stacking Only Attack Speed

Without damage, you're just tickling enemies faster. Always have a damage foundation before adding attack speed.

Ignoring Attack Speed Caps

Going beyond the cap wastes gold and item slots. Check your game's AS cap and plan accordingly.

Building AS on Casters

If your champion's kit is ability-based, attack speed provides minimal value. Focus on CDR and ability power instead.

Neglecting Defensive Stats

DPS is zero when you're dead. Even carries need some defensive items to survive burst and focus fire.
