The amount of health a unit gains from lifesteal is calculated after all damage reductions such as Armor and Damage Block. A unit can lifesteal from Illusions, but the amount is calculated before the damage amplification.
Lifesteal stacks additively.
|Broodmother||Insatiable Hunger||60% / 90% / 120%|
|Chaos Knight||Chaos Strike||75% (only on critical hits)|
|Legion Commander||Moment of Courage||55% / 65% / 75% / 85%|
|Lifestealer||Feast||4.5% / 5.5% / 6.5% / 7.5% |
of current enemy HP
|Monkey King||Jingu Mastery||20% / 30% / 40% / 50%|
|Wraith King||Vampiric Aura||15% / 20% / 25% / 30%|
|Mask of Madness||Lifesteal||15%|
|Vladmir's Offering||Vladmir's Aura||15% for Melee units|
|10% for Ranged units|
Spell Lifesteal behaves as a separate mechanic from normal lifesteal. Rather than basic attacks, it heals the user based on damage from spells. All spell lifesteal abilities can stack with each other. They do not stack with identical spell lifesteal sources.
|Pugna||Life Drain||100% of Life Drain's damage|
|Octarine Core||Spell Lifesteal||25% of spell damage dealt to heroes|
|5% of spell damage dealt to units|
