Omnivamp is a League of Legends stat that heals you for a percentage of every point of damage you deal — whether that damage comes from a basic attack, an ability, or an item active. It is the most broadly applicable form of healing in the game, making it a staple of drain-tank fighters who need to sustain through long trades.
Understanding omnivamp is essential if you play bruisers, fighters, or any champion whose goal is to dish out sustained damage while staying alive in a fight. This guide explains exactly what it does, how it compares to older healing stats like lifesteal, what triggers the reduced-efficiency penalty, and which items and runes grant it.
What Omnivamp Does
At its core, omnivamp works like this: every time you deal damage to an enemy, you recover HP equal to your omnivamp percentage multiplied by the damage dealt. It does not matter whether the damage is physical, magic, or true, and it does not matter whether it was triggered by a basic attack, an ability, or an item passive or active — omnivamp heals from all of it.
For example, if you have 12% omnivamp and you hit an enemy for 200 damage, you immediately heal 24 HP. Do that repeatedly across a team fight and the effect adds up quickly, turning a champion that looked like it was losing a trade into one that is steadily recovering.
Omnivamp vs Lifesteal vs Spellvamp
Prior to Season 2024, League of Legends had three separate healing stats for different damage sources. Lifesteal only healed from basic attacks, while spellvamp only healed from ability damage. Both were removed in later updates and consolidated into omnivamp, which covers everything.
This consolidation was a deliberate design choice to reduce complexity. Instead of building separate items for attack healers and spell healers, you now look for a single stat. The trade-off Riot introduced to keep omnivamp balanced is the AoE efficiency penalty, which is covered in the next section.
The AoE and DoT Efficiency Penalty
Here is the key caveat: when your damage hits multiple targets at once (area-of-effect abilities) or deals damage over time (DoT effects), omnivamp heals at only 33% of its normal efficiency. So with 12% omnivamp, a single-target hit for 100 damage heals 12 HP, but an AoE hit that deals 100 damage to several enemies heals only about 4 HP.
This penalty exists to prevent champions with heavy AoE kits — mages especially — from becoming nearly unkillable simply by stacking omnivamp. It means the stat rewards focused, single-target damage more than splash damage, which is part of why fighters and bruisers benefit so much more than mages do.
Items and Runes That Grant Omnivamp
Omnivamp is built into a handful of fighter and bruiser items. Here are the most commonly built sources:
- Goredrinker — grants roughly 8% omnivamp and includes an active that deals damage in an area while also healing you.
- Sterak's Gage — one of the higher omnivamp items, granting around 20%, combined with a life-saving shield passive.
- Ravenous Hydra — around 15% omnivamp paired with AoE wave-clear, making it popular on split-push fighters. Note that the AoE splash healing is subject to the 33% penalty.
- Divine Sunderer — provides omnivamp through its Spellblade passive, rewarding champions who weave abilities between auto attacks.
- Conqueror (rune) — grants up to about 8% omnivamp when fully stacked, making it the most accessible rune-based source for fighters.
Which Champions Benefit Most
Omnivamp shines brightest on champions that deal high, sustained, mostly single-target damage and spend extended time in melee range. Fighters and bruisers like Darius, Aatrox, and Garen are natural fits: they stay close to enemies, deal damage repeatedly with both auto attacks and abilities, and have the bulk to survive long enough for the healing to matter.
AD carries can make use of omnivamp, though lifesteal-flavored items historically covered their needs more efficiently. Mages get the least value because their damage is almost entirely AoE and DoT-based, meaning they almost always trigger the 33% penalty and heal far less than their omnivamp stat would suggest.
Tips for Using Omnivamp Effectively
- Prioritize single-target trades. When you have heavy omnivamp, extended one-on-one duels are where you recoup the most health. Avoid relying on it to sustain through AoE poke.
- Stack it with a healing amplifier. Items or runes that boost healing and shielding (such as the Revitalize rune) amplify your omnivamp output, making each hit heal more.
- Pair Ravenous Hydra with caution. The AoE splash is great for waveclear, but remember the 33% penalty means you heal far less from the splash than from the primary strike.
- Know when enemies have Grievous Wounds. This debuff — triggered by many items and champion abilities — reduces incoming healing including omnivamp by 40–60%. In those moments, sustaining through a fight becomes far less reliable.
Frequently Asked Questions
Does omnivamp heal from damage dealt to structures like turrets?
No. Omnivamp only triggers from damage dealt to enemy champions and certain monster units. Turret and structure damage does not count toward omnivamp healing.
Does omnivamp stack with lifesteal?
Lifesteal no longer exists as a separate stat in League of Legends following the Season 2024 itemization rework. Omnivamp is now the sole universal sustain stat, so stacking multiple omnivamp sources is the way to increase your healing output.
How does omnivamp interact with Grievous Wounds?
Grievous Wounds reduces the effectiveness of all healing, including omnivamp, by 40% (or 60% from stronger applications). This makes it the primary counter to omnivamp-heavy drain-tank builds.
Does omnivamp apply to damage dealt by my team?
No. Omnivamp only heals the champion who personally deals the damage. Ally damage does not trigger your omnivamp.
Is omnivamp worth building on ability-heavy champions?
Generally not as a primary source. Because AoE ability damage triggers the 33% efficiency penalty, ability-heavy mages and mage supports see very little healing from omnivamp. It is far more valuable on fighters who mix auto attacks and short-cooldown single-target abilities.
The Bottom Line
Omnivamp is League of Legends' universal healing stat — it recovers HP from every source of damage you deal, making it the go-to sustain option for fighter and bruiser champions. The key rules to remember are that single-target damage heals at full efficiency, AoE and DoT damage heals at 33% efficiency, and Grievous Wounds cuts all of it down significantly.
