Critical strike

A critical strike is a basic attack or ability that deals 175% of its normal damage by default.

All basic attacks and some abilities can critically strike. Most champions cannot critically strike structures. The exceptions are Fiora, Jhin, and Master Yi.

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

Critical strike chance

Critical strike chance is the chance that a basic attack of a champion critically strikes. Every champion starts with 0% critical strike chance, and level-ups do not increase the critical strike chance.

Critical strike chance can be increased with items and abilities; it stacks additively, and each bonus point acquired directly affects its statistic. It cannot be increased beyond 100%, although some effects will benefit from the stat despite the cap.

Gold Value ​​​​​​​​​​: Critical strike chance has a gold value of 40 per point.

Critical strike chance changes dynamically based on how many times the champion did not critically strike. For instance, with 30% critical strike chance, it is guaranteed that the champion will have roughly 30 critical strikes for every 100 attacks. If the champion did not critically strike for a long period of time, their future attacks will have a higher probability of critically striking, and vice versa; if the champion has been critically striking subsequently overtime, their future attacks have a lesser probability of critically striking.

When averaged over a high number of basic attacks, critical strike chance is essentially a damage multiplier. At base critical damage (75% bonus damage) every 1% of added critical chance adds 0.75% bonus damage. For example, the damage dealt with basic attacks by a champion with 50% critical strike chance and base critical damage is on average 137.5% of the damage they would deal if they had 0% critical strike chance. For this reason, the critical strike chance scales well with both attack damage and attack speed. The formula for this damage multiplier is:

Damage multiplier = 1 + (Critical chance × (0.75 + Bonus critical damage))

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.
• Most champions have special basic attack animations when they critically strike, even champions that do not itemize critical strike chance. Other champions have a sound that plays when they critically strike, typically a grunt of effort.
• 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.
