Lifesteal



Lifesteal is a mechanic that allows the attacking unit to gain health when damaging an enemy, which includes any attack modifiers with attack damage. The lifesteal ability can be gained via items, passive abilities or from auras of other units.

Mechanics
The amount of health a unit gains from lifesteal is calculated by a percentage of the total attack damage done to the attacked unit. Therefore, lifesteal heals more on attacks that crit. Usually, if an attack's damage exceeded the target's current health and killed it, the heal is based on damage it would have taken if it would not have died. However, lifesteal is not affected by most damage manipulation effects on the target, such as or.

Lifesteal does not work for magical or pure attack damage (e.g. procs or ), and only physical attack damage is considered when determining the heal amount.

With illusions, they are able to lifesteal but using their modified outgoing damage values. However, when attacking illusions, the heal is not affected by the illusion's incoming damage values.

Instant attacks hitting secondary targets can lifesteal as long as the instant attack can be affected by attack modifiers.

Percentage-based Lifesteal provided by items heals for % of their usual value when attacking creeps (including, excluding Creep-Heroes).

All sources of lifesteal stack additively with each other, and lifesteal manipulation sources stack multiplicatively.

Attack Modifier Interactions
An attack can lifesteal if the attack modifier directly adds physical or pure damage to the attack damage it deals (i.e. bash sources).

Pseudo-Lifesteal
Some lifesteal abilities work differently from regular lifesteal. Their mechanics are unique to the spell they are provided by.
