A critical strike is a basic attack or an ability that deals twice its normal damage.

All basic attacks can critically strike, but only a few abilities can. It's not possible to critically strike structures, with the exception of JhinSquare Jhin, whose fourth shot can crit against structures, with reduced damage.

Most champions have special attack animations for critical strikes. This includes mages and other champions not meant to be built using basic attacks for damage. Other champions have a sound that plays when they critically strike, typically a grunt of effort.

Players can increase their chances to critically strike and the damage they deal with critical strikes using items, abilities, and runes. Critical strikes are specially valuable for champions who deal damage primarily with basic attacks rather than abilities. Some champions, like AsheSquare Ashe, have an affinity for critical strikes and benefit more than others from items that improve them.

Chance

Critical strike chance is a stat that is the percentage of chance that a basic attack of a champion critically strikes.

Every champion starts with 0% critical strike chance, and level-ups do not grant additional critical strike chance.

Critical strike chance can be increased with items, abilities, and runes, it stacks additively, and each bonus point acquired directly affects its statistic.

Critical strike chance cannot be increased beyond 100%.

Gold Value ​​​

  • Critical strike chance has a gold value of Gold 40 per point.

General

  • Critical strike chance will adjust dynamically based on the number of basic attack that didn't critically strike. At 30% critical strike chance you're sure to have 30 or more attacks critical strike per 100 attacks. If you didn't critical strike for a long time your next attacks will have a higher chance.
  • When averaged over a large number of autoattacks and at base critical damage (100% bonus damage), critical strike chance is essentially a damage multiplier where each 1% of critical chance adds 1% bonus damage.
    • Thus at 50% critical strike chance a champion deals (on average) 150% damage with autoattacks, not counting bonus critical strike damage. Because of this, critical strike chance scales well with both attack damage and attack speed. The formula for this damage multiplier is:
Damage multiplier = 1 + (Critical chance × (1 + Bonus critical damage))

Modifying Critical Strike Damage

Notes
  • Most champions deal 200% the normal damage when they critically strike.
  • The exceptions are JhinSquare Jhin, with 150% damage (reduced to 112% vs structures); and YasuoSquare Yasuo, with 180%.
  • In most cases, critical strike damage stacks additively.
  • Damage modifiers apply to critical strike damage normally.

Champion Abilities

  • FioraSquare Fiora's Bladework Bladework modifies her base critical damage to 140 / 155 / 170 / 185 / 200% from the default of 200% on her second auto attack.
  • JhinSquare Jhin's Whisper Whisper multiplicatively reduces his total critical damage by 25% for basic attacks (e.g. 200% to 150%).
  • ShacoSquare Shaco's Backstab Backstab modifies his base critical damage to 130% from the default of 200%.
  • YasuoSquare Yasuo's Way of the Wanderer Intent multiplicatively reduces his total critical damage by 10% for basic attacks (e.g. 200% to 180%).
  • Note: AsheSquare Ashe's Frost Shot Frost Shot does not modify the base critical damage. Instead, it does the following:
    • Only allows critical strikes on auto-attacks against targets affected by Frost Shot 2 Frost.
    • Removes the randomness of critical strikes. It does so by simultaneously increasing the proc probability to 100% and reducing the extra damage on proc by the same multiplicative factor.
    • Adds straight 10% multiplicative bonus damage that is unrelated to critical strikes.

Abilities Affected by Critical Chance

Champions

Basic attack modifiers

Many abilities in the game enhance basic attacks, causing them to deal increased damage. Since these are auto attacks, they can critically strike with the exception of Twisted FateSquare Twisted Fate's Pick a Card Pick a Card and the first strike of FioraSquare Fiora's Bladework Bladework which can never critically strike. If the the basic attack critically strikes then the ability's damage will be included for the purposes of Infinity Edge item Infinity Edge's passive (with the exception of ViktorSquare Viktor's Discharge Discharge). However, the ability damage itself will only be amplified by a critical strike for the following abilities:

  • JhinSquare Jhin's Whisper Whisper: The fourth shot will always critically strike.

Trivia

  • In many MMO settings, a number of attack damage-based assassins or secondary assassin-based champions also benefit from high critical strike chance in varying forms, as a means to help finish off targets faster as well as to deal more damage in bursts overall.
  • Some champions may actually use their critical strike animation for their empowered-basic attack if they ever activate a single-use on-hit effect, only it does not actually count as an actual critical strike.

  • Critical Strike Chance Amplification:
  • Relevant mathematics:
    • YasuoSquare Yasuo Critical Strike Chance = (Brawler's Gloves item 10% + Zeal item 15%) × Infinity Edge item 2 × Way of the Wanderer 2 = 100% critical chance
