Lifesteal heals the attacking unit while damaging an enemy. Certain attack modifiers that deal damage in a single instance as the attack damage may conditionally Lifesteal. A unit can gain Lifesteal from abilities, items or talents granting percentage-based values (e.g. Morbid Mask).

Total Lifesteal

Percentage-based lifesteal sources from items, abilities, and talents stack independently and additively of each other after the sources' respectively creep lifesteal multiplier. All lifesteal sources are summed up, then lifesteal amplification is applied to the unit's lifesteal value as a multiplier. All lifesteal manipulation sources stack multiplicatively of each other.

The heal value from lifesteal is based on a percentage of the total physical attack damage dealt to the attacked unit from the attacking unit. Therefore, if an attack damage instance exceeds the target's current health and kills it, the heal value is based on the attack damage value the dying target would have received if it had not died. Lifesteal heals more on critical strike procs and works conditionally on certain attack modifiers.

Neither heals from magical attack damage sources (e.g. Monkey King Bar procs) nor spell damage sources of all damage types. Lifesteal only heals from physical attack damage.

Instant attacks hitting secondary targets can heal from lifesteal as long as attack modifiers work with the instant attack source.

However, the heal value from lifesteal is not affected by most damage manipulation effects on the attacked target (e.g. Flesh Golem or Aeon Disk). For example, for illusions, their heal value from lifesteal is based on their outgoing damage manipulation values (i.e. total attack damage of the illusion), but the heal value from attacking illusions is not affected by the incoming damage manipulation values (i.e. attacking illusions).

There are currently no limits to how much a unit can heal from lifesteal.

Percentage-based lifesteal sources from items heals for 40% of their usual value when attacking creeps. Treats attack against clones, illusions and creep-heroes as heroes, attacks against Roshan as creeps.

Calculating the total lifesteal value of a unit involves using a few values and a multiplier and can be defined as:

• Total Lifesteal
  • ± Lifesteal Sources
    • × Creep Lifesteal Multiplier
  • + Shared Lifesteal Sources
    • × Creep Lifesteal Multiplier
    • × Source Lifesteal Amplification
  • × Wielder Lifesteal Amplification

Conditional Attack Damage Bonus

Main Article: Conditional Attack Damage Bonus

These abilities give direct attack damage bonuses under certain circumstances, these bonuses are not displayed in the HUD and its damage type is not limited to physical damage; nonetheless, they are considered as attack damage since it is dealt in one instance together with a unit's attack damage. Only physical conditional attack damage bonuses increases the healing value from lifesteal.

Pseudo-Lifesteal

Some lifesteal sources work differently and conditionally, their mechanics are unique to the sources themselves. More information can be found in their ability's respective notes.

• Lifestealer - Open Wounds
  
  Heals everyone for all the damage they deal to the debuffed target, including spell damage.
• Lone Druid - Spirit Link
  
  Heals Lone Druid based on the attack damage dealt by his Spirit Bear.
  When cast on an allied hero, the Ability Upgrade heals the affected target based on the attack damage dealt by Lone Druid instead.
• Lycan - Wolf Bite
  
  The lifesteal is granted to the ally immediately upon cast. Grants regular lifesteal and shared lifesteal to both, the caster and the target.
  The shared lifesteal heals both the caster and target as long as they do not exceed the penalty distance.
• Marci - Sidekick
  
  The lifesteal is granted to the ally immediately upon cast. Grants regular lifesteal and shared lifesteal to both, the caster and the target. Applies penalty multiplier to both the lifesteal and shared lifesteal values when the distance between Marci and the affected target exceeds the penalty distance.

Spell Lifesteal

Main Article: Spell Lifesteal

Spell lifesteal allows the hero to heal from spell damage they deal. Just like attack damage lifesteal, spell lifesteal is calculated by a percentage of the actual damage done to units. However, unlike attack damage lifesteal, it does not heal for overkill damage dealt to a unit, so if a spell's damage exceeded the target's current health and killed it, the heal is based on the target's remaining health.

Does not interact with pure spell damage sources.

Lifesteal applies to physical damage from attacks and is reduced by 40% when damaging non-heroes Spell Lifesteal now applies to physical damage from spells and magical damage from spells or attacks and is reduced by 80% when damaging non-heroes Neither Lifesteal nor Spell Lifesteal applies to pure damage Holding Alt while looking at items that provide Lifesteal or Spell Lifesteal will show the lifesteal percentages for attacking and casting spells, and targeting creeps vs heroes The following sources and targets do not provide any lifesteal Attacks that do not proc Attack Modifiers Attack damage against wards, buildings, or couriers Spell damage against illusions, wards, buildings, or couriers Reflected damage Spells that remove Health instead of dealing direct damage Any damage dealt to self or allies A small number of abilities that do not use Lifesteal or Spell Lifesteal still result in healing and can benefit from Lifesteal Amp: Lifestealer's Open Wounds heals attackers for a percentage of the damage done Lifestealer's Feast heals for a percentage of the target's max health
