Info
Critical strike is a passive ability that gives a chance to deal bonus damage on a successful attack.
Mechanics

Critical strike is defined by two values: the critical chance and the critical damage multiplier.
Critical damage is physical damage Damage is any means by which unit s current health can be reduced. Heroes, creeps, ancients, Roshan and fountains are all capable of dealing damage. Contents 1 Damage sources 1.1 Attack damage 1.2 Spell damage 2 and is reduced by various types of armor. When a critical strike triggers, the unit`s attack damage number visible in the HUD gets multiplied by the critical strike`s factor. The result of this multiplication shows up as a red number above the target if the attack successfully hits it. This means that the red number displays the damage before any kind of damage reduction or amplification the attack target has. This also goes for illusions. The red number shows the result of the illusion`s attack damage multiplied by the factor, before it gets reduced by the illusion`s outgoing damage reduction and armor. Critical strike does not work against buildings Buildings are special units that are immune to most spells, use structure armor, and are immobile. Destroying a building rewards you with a bounty, similar to most creeps or heroes. Destroying towers rewards the entire , and only very few work against wards This page is about in-game units. For cosmetic pets, see Summoned Unit. Summons are a type of units that are created with spells. Players do not encounter them, unless they play as, with or against
. Because critical strike multiplies the attack damage of a unit, after attack damage modifiers, it is a scaling ability (unlike the damage of Monkey King Bar For the hero, see Monkey King.

`s mini-bash ability).
All critical strikes are subject to pseudo-random distribution.
A ranged critical strike is calculated on projectile ejection rather than on impact. For example a unit which already lost the Soul Rend debuff on impact, still gets struck by critical hit.

Stacking
Multiple critical strike abilities do not independently stack, as they cannot trigger on the same hit.

Chance Stacking Formula
Multiple critical strike damage percentages do not stack. However the chance can stack based on the following formula:
- (1 - critical chance) ₂ₗ (1 - next source of critical chance) = (1 - chance to not crit) = critical strike chance
If critical strike chance is 100% through a given ability, then that critical strike will override and prevent other sources of crit from activating.
