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.
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
Your starting attack speed determined by your character/class and weapon type. Different weapons have different base values (daggers are faster, axes are slower).
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
- → 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
- → 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.
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.
Your base damage per hit. Without sufficient AD, attack speed just hits faster for less.
How often you deal damage. Amplifies your AD and enables on-hit effects to proc more.
Multiplies your damage through RNG. Works with both AD and AS to create burst potential.
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
Without damage, you're just tickling enemies faster. Always have a damage foundation before adding attack speed.
Going beyond the cap wastes gold and item slots. Check your game's AS cap and plan accordingly.
If your champion's kit is ability-based, attack speed provides minimal value. Focus on CDR and ability power instead.
DPS is zero when you're dead. Even carries need some defensive items to survive burst and focus fire.
