A critical strike deals extra damage during an attack. This could represent an attack that hits harder, a lucky strike or damaging a weak area on an opponent.
Most champions have different attack animations for critical strike.
Players can increase the chance and the damage of critical strikes with items, abilities, and runes.
It only applies to basic attacks or certain spells like 普朗克的 Parrrley that act like a basic attack or 盖伦的 Judgment, which is something unique.
Critical strike is valuable for all champions who primarily deal damage with automatic attacks, rather than through abilities. Some champions, such as Ashe, have an affinity for critical hits and benefit more from items that improve them.
It's important to note that you cannot score a critical strike against a building such as a tower or inhibitor.
Chance
Critical strike chance is the chance of a champion's basic attack dealing a critical strike. Critical strike chance stacks additively. Runes, items and abilities can increase critical strike chance.
The maximum critical strike chance you can reach at level 1 without items is 20.25%, excluding Ashe's and Tryndamere's passive.
Critical strike chance has a hard cap at 100%, at which point all of your basic attacks will be critical strikes.
