* Heroes that rely on their high mobility such as Queen of Pain, Slark and Weaver can be constantly engaged against due to your excellent ability to chase over any terrain. Make sure you carry true sight items (such as Dust of Appearance or Gem of True Sight) for invisible heroes that could potentially escape your clutches.

* Lifestealer is not affected by Earthbind or Poof during Rage, making him a difficult target to work around.

* With Aghanim's Scepter upgraded Infest, Lifestealer can use it on enemy heroes to attack them and disarm them from inside, even if they are spell immune, which can give him the edge over the heroes he's weak against like Ursa, Phantom Assassin, Terrorblade or Troll Warlord.

* Heroes with spell immunity or pseudo-blinks which provide invulnerability: Lifestealer, Juggernaut, Omniknight, Huskar, and Tusk have spells which allow them to easily escape Dream Coil.

* Heroes with built-in spell immunity can become immune to all of Outworld Destroyer's spells: Lifestealer's Rage and Juggernaut's Blade Fury.

* Heroes with mobility/escape mechanisms to dodge Ancient Apparition abilites, or to easily jump on him: Riki, Queen of Pain, Phantom Assassin, Windranger, Bounty Hunter, Spirit Breaker, Night Stalker, Storm Spirit, Juggernaut, etc.

Additional:
* Ancient Apparition's only skill to stop Storm Spirit is Cold Feet, which is bad in general when trying to stop a Storm Spirit without any other disable.
* As a fragile support with low Strength gain and no magic resistance, Ancient Apparition is vulnerable to Storm Spirit's combos.

* Any hero with teleport abilities (e.g. Ember Spirit, Storm Spirit) can easily break Static Link.

Additional:
* Ball Lightning breaks Static Link.
* Razor has no way to catch a slippery Storm Spirit.

* Heroes that rely on their high mobility such as Queen of Pain, Slark and Weaver can be constantly engaged against due to your excellent ability to chase over any terrain. Make sure you carry true sight items (such as Dust of Appearance or Gem of True Sight) for invisible heroes that could potentially escape your clutches.

* Escape-type carries: Slark, Storm Spirit, Weaver.

* Ball Lightning makes it almost impossible to catch Storm Spirit without someone else initiating for you.
* Overload is not reduced by Bulwark and the magical damage spam can wear down Mars quickly.
Additional:
* Storm Spirit's abilities all do magical damage, which can bypass Bulwark.
* Ball Lightning can escape through Arena of Blood and it is easy to dodge Spear of Mars.

* Rage, acting as a pseudo-Black King Bar, completely negates Mars' initiation if used in time.
* Feast does damage and heals based on max health, perfect against high-health strength heroes like Mars.
* Infest allows Lifestealer to potentially save allies from Mars' initiation with a quick burst of extra health.

* Storm Spirit can close the distance towards Sniper very easily with his ultimate Ball Lightning.
Additional:
* Sniper is very squishy and cannot deal with heroes that jump onto him and lock him down. Storm Spirit closes the gap in a fight against Sniper, and Sniper has no way to escape except for some items.
* Storm Spirit can dodge Assassinate with a correctly timed Ball Lightning.

* Lifestealer can close the distance to Sniper by using Infest on a fast or durable creep to tank Sniper's damage.
* Open Wounds and Ghoul Frenzy will reduce Sniper's mobility heavily, and Rage's movement speed bonus helps in closing the gap to Sniper. It also protects him from Assassinate and Shrapnel.
* Infest can dodge an incoming Assassinate or to surprise Sniper during ganks. Aghanim's Scepter upgraded Infest can also allow Lifestealer to disarm Sniper and attack him from inside.

* Storm Spirit can exploit every one of Spectre's weaknesses, and thus is one of the best counters against her.
* Spectre has to be in melee range to deal damage, making her likely to trigger Static Remnants and susceptible to being kited by Overload procs.
* Electric Vortex can lock Spectre down as she doesn't like to build Black King Bar.
* Ball Lightning gives Storm Spirit multiple advantages:
* Spectre cannot evade Storm Spirit, as Ball Lightning is superior to Spectral Dagger in terms of mobility.
* Storm Spirit can kite her and her Haunt illusions when it's later in the game due to her having no form of pseudo-blinks (Reality is far inferior to Ball Lightning).
* It is very difficult for Spectre to deal any substantial damage against Storm Spirit with Desolate. Ball Lightning grants invulnerability and can mitigate damage done from Dispersion and Radiance.
* To mitigate this, Spectre needs a team with hard disable to take Storm Spirit out.
Additional:
* Ball Lightning is the ultimate counter to Spectre's entire toolkit. With this ability, he can score easy kills on Spectre without her having any means of escape early game, kite her and her Haunt illusions when it's later in the game due to her having no form of pseudo-blinks.
* Furthermore, it is very difficult for Spectre to deal any substantial damage against Storm Spirit with Desolate, and without both Manta Style and Diffusal Blade he will always remain on the move.
* Also, Ball Lightning grants invulnerability, and as Storm Spirit likes to spam that ability, he can mitigate the damage done from Dispersion and Radiance.

* Feast deals damage and heals lifestealer based on the target max health. Because Spectre often emphasises on building stat items to increase her HP pool, lifestealer can deal a lot of damage to her and heal himself at the same time.
* Ghoul Frenzy slows target, which is bad for Spectre if she does not have Spectral Dagger ready.
* Spectre cannot response to infest if lifestealer choose to stay inside his high mobility allies to approach the backline. Rage's bonus movement speed and spell immunity make it even more frustrating.

* Ball Lightning allows Storm Spirit to bypass Bramble Maze into the backline, and zip back into battle if he gets hit by Terrorize.

* Rage protects and dispels all of Dark Willow's abilities.
Additional:
* Rage protects Lifestealer from all of Dark Willow's abilities.

* Ball Lightning allows Storm Spirit to escape through Viper Strike, wasting Viper's mana.
* It's also very easy to wait out the duration of Nethertoxin's break.

* Rage ignores all of Viper's magical damage, although Viper Strike can pierce spell immunity and slows him down.
* Feast and Open Wounds from Aghanim's Shard can be combined to heal through Viper's physical damage.
* Aghanim's Scepter upgraded Infest can be used to disarm Viper, preventing him from using Poison Attack on Lifestealer's allies.

* Storm Spirit destroys trees and ignores impassable terrains with Ball Lightning, rendering them dangerous places for Tinker to hide within.
* Ball Lightning disjoints projectile from Heat-Seeking Missile and damage from March of the Machines.
* Electric Vortex prevents Tinker from teleporting away, and Static Remnant and Overload can easily burst him down.
Additional:
* He can easily catch Tinker in the trees with Ball Lightning and kill him with Orchid Malevolence and his abilities, which deal both physical and magical damage, making them difficult for Tinker to itemize against.

* Lifestealer's Rage makes him immune to all of Tinker's damage and debuffs.
* Lifestealer can infest a mobile ally (teams usually pick one against Tinker), which may ensure that Tinker will die if he is caught.
Additional:
* Rage will dispel Laser's blind and turns him spell immune for the duration so Tinker cannot damage him.
* Feast will quickly bring down Tinker due to being so fragile.

* Heroes that can easily bypass Chen's creeps to get to Chen: Riki, Tusk, Clinkz, Sniper, Slark, Phantom Assassin, Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, Spirit Breaker.

* Rage gives Lifestealer spell immunity, Chen and his converted creeps have little to no ways of fighting back against Lifestealer whenever he activates it.
* Feast allows Lifestealer to recover himself by damaging Chen's creeps.
* Chen has no escape mechanisms, so he will often be unable to escape from slows applied with Ghoul Frenzy.
* Open Wounds from Aghanim's Shard can severely slow down Chen, and allow Lifestealer and his team to heal themselves by attacking Chen. Open Wounds can also fester and spread if Chen takes enough damage that will trigger the spread while he is affected with Open Wounds.
* Infest allows Lifestealer to infest into one of Chen's converted creeps and take control of it, which allows Lifestealer to either escape from Chen or surprise him. Aghanim's Scepter upgraded Infest can disarm Chen and allow Lifestealer to attack Chen from within, even if Chen is spell immune.

* Heroes with high mobility will be able to avoid Gyrocopter's area attacks: Storm Spirit, Morphling, Ember Spirit

* Rage ignores all of Gyrocopter's magical attacks.
* Feast helps Lifestealer out-damage Gyrocopter at close range.

* Heroes with teleports to escape Solar Blind and Will-O-Wisp: Phantom Assassin, Puck, Queen of Pain, Storm Spirit

* Rage allows him to be immune to all of Ezalor's abilities. Also, the increased movement speed combined with the slow from Ghoul Frenzy and the squishy nature of Ezalor allows Lifestealer to take him down very quickly.

* Heroes with invisibility and high mobility can jump on and focus down Earthshaker before he has a chance to initiate: Clinkz, Slark, Storm Spirit

* Rage prevents Earthshaker from damaging and stunning Lifestealer.
* Feast is very effective against Earthshaker, because of him being a strength hero, allowing Lifestealer to heavily harass and kill him.
* Open Wounds prevents Earthshaker from escaping after he initiated.
* Infest gives Lifestealer an easy way to escape should he get caught out by Earthshaker. And against carry Earthshaker, Aghanim's Scepter upgraded Infest can be used to disarm Earthshaker and attack him from within, rendering him unable to attack with Enchant Totem.

* Heroes that can reliably kite out Dispose, Unleash and dodge Rebound, like Ember Spirit, Void Spirit, Storm Spirit, Anti-Mage, Faceless Void, Puck or always build items like Blink Dagger and Force Staff.

* Lifestealer's Rage renders him immune to all of Marci's disables and magic damage for a good duration.
* His passive Feast deals bonus damage based on the enemy's max health and heals for the same amount. As a tanky Strength hero, Marci's own strength will be her undoing as well.

* Storm Spirit can hunt down Arc Warden with his Ball Lightning and kill him quickly due to his lack of escape abilities.
* None of his abilities are effective against Storm Spirit, as they can be evaded with Ball Lightning.

* Heroes with good escape mechanisms are a nuisance to deal with in the early phase of the game: Slark, Lifestealer, Morphling

* In the early to mid game, Invoker is defenseless against Storm Spirit's ganking with Ball Lightning and Orchid Malevolence.

* Rage grants immunity from Invoker's spells and can dispel most of the disables such as the armor loss from Forge Spirit and the constant stuns of Cold Snap.
Additional:
* Rage protects Lifestealer from all of Invoker's spells (except for Sun Strike).

* Zeus can deal a huge amount of damage, but he lacks defensive abilities, such as good mobility or resistance. Due to that, he doesn't like to be touched by any means. Heroes with higher damage output and good mobility will often get easily near Zeus and trade damage (eventually causing Zeus's downfall). Such Heroes include: Lycan, Slark, Storm Spirit, Spectre and others.

* Heroes who have most or all their abilities (damage or disable) unable to pierce spell immunity: Keeper of the Light, Lina, Lion, Zeus.

Additional:
* Rage is very useful against Zeus, as it negates magic damage and provides spell immunity. In addition, the increased attack speed can tear Zeus apart in combination with Open Wounds.
* Lifestealer can avoid Thundergod's Wrath with Infest.

* Heroes that can easily bypass Io's allies to get to Io: Riki, Tusk, Clinkz, Sniper, Slark, Phantom Assassin, Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, Spirit Breaker, Lifestealer.

* Heroes that can easily bypass Io's allies to get to Io: Riki, Tusk, Clinkz, Sniper, Slark, Phantom Assassin, Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, Spirit Breaker, Lifestealer.

* Heroes that are naturally hard to gank, ranging from beefy tanks like Abaddon and Wraith King to heroes with quick escape mechanisms like Anti-Mage and Storm Spirit are also undesirable targets for a lone, roaming Bounty Hunter to scout out and initiate on.

* Lifestealer with Rage and Infest
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with Mirror Image
* Omniknight with Heavenly Grace
* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.

* Heroes with abilities that can close the gap can easily kill Muerta: Storm Spirit, Earth Spirit, Ember Spirit, Void Spirit, Lycan, Chaos Knight, Tusk.

* Lifestealer can activate Rage to become spell immune, making Pierce the Veil do no damage and preventing Dead Shot from fearing or doing damage.
* Lifestealer can use Infest to avoid Muerta's Gunslinger shots, Dead Shot's fear and surprise Muerta. Aghanim's Scepter upgraded Infest can be used to disarm Muerta while she has Pierce the Veil and even through Black King Bar.
* However, Lifestealer has no way of hurting Muerta through Pierce the Veil outside of Infest, Lifestealer's only source of dealing magical damage. This forces Lifestealer to buy Revenant's Brooch.

* Storm Spirit can easily make his way to Hoodwink with his ultimate Ball lightning, and coupled with Hoodwink's low health and magic resistance, she can be nuked easily.
* Additionally, Ball lightning can destroy a small amount of trees in its destination. Combined with Storm Spirit's frequent usage of his ultimate, he can clear out an area of trees while simultaneously attacking him and dodging incoming attacks.

* Feast will deal a enormous amount of damage because of Tiny's huge health pool.
* Rage protects Lifestealer from Tiny's magical burst damage.

* Rage renders Lifestealer immune to the damage from Burning Spears.
* Feast makes Lifestealer one of few heroes that can outlast Huskar in a one-on-one fight.

* Ball Lightning makes Storm Spirit a target difficult to chase, even for a hero as mobile as Timbersaw.
* The magical damage from Static Remnant and Overload together with Storm Spirit's high mobility allows Storm Spirit to jump on Timbersaw and burst him down, even if he tries to escape.

* The lifesteal of Feast scales accordingly to the max health of its target, which is effective against Pudge due to his high health and further health granted by stacks of Flesh Heap.
* Lifestealer can activate Rage to be spell immune, making Rot deal no damage.
* Pudge's plentiful health makes him an ideal target for Lifestealer's Aghanim's Shard ability, Open Wounds.

* Being a strength hero with a high strength gain means Feast can give her a hard time,especially later in the game.
* However,Starbreaker's physical damage can control him in the laning phase.

* Rage grants Lifestealer immunity to all of Jakiro's spells. Note: magic resistance will not dispel the attack speed slow effects from Dual Breath and Liquid Fire.

* Leshrac's high magic damage is ignored by Rage.
* Lifestealer can get in Leshrac's face with Rage and mitigate any other damage taken by Leshrac with Open Wounds.

* Feast is good against high health strength heroes such as Alchemist.
* Rage allows Lifestealer to not be targetable by Unstable Concoction, possibly making Alchemist stun himself.

* Lifestealer's Rage makes him immune to all of Ogre's magical debuffs and also dispels them.
* Ogre's high health pool makes him an ideal target for Feast.
Additional:
* Ogre Magi has nothing against Rage and his high health pool amplifies Feast.

* Storm Spirit outlanes Earth Spirit wins by having a ranged attack type, and also deals damage to the Earth Spirit every time he approaches the creeps with his ability Static Remnant, which is why he overtakes Earth Spirit in level and gold
* Storm Spirit has the ability to quickly kill Earth Spirit under his ability Electric Vortex, which Earth Spirit cannot do if Storm Spirit buys Falcon Blade at the liner stage, because Storm Spirit will have too much health for Earth Spirit`s abilities and will survive Earth Spirit`s damage.
Additional:
* Storm Spirit outlanes Earth Spirit wins by having a ranged attack type, and also deals damage to the Earth Spirit every time he approaches the creeps with his ability Static Remnant, which is why he overtakes Earth Spirit in level and gold
* Storm Spirit has the ability to quickly kill Earth Spirit under his ability Electric Vortex, which Earth Spirit cannot do if Storm Spirit buys Falcon Blade at the liner stage, because Storm Spirit will have too much health for Earth Spirit`s abilities and will survive Earth Spirit`s damage.

* With Feast and Rage, Lifestealer is nearly impossible for Clockwerk to bring down, and is the last hero Clockwerk wants to be trapped with in Power Cogs.

* Feast is an effective tool against Centaur Warrunner, who generally has high health and low armor, and compensates the reflected damage of Retaliate.
* If activated, Rage can protect Lifestealer from Hoof Stomp, Double Edge, and Stampede.
Additional:
* Centaur Warrunner's active abilities cannot pierce magic immunity. Hoof Stomp's slow wind up can also be anticipated and negated with Rage.
* Lifestealer can offset Retaliate's damage return simply with Feast. Centaur's high strength gain and therefore big health pool makes him an ideal target to Feast on, especially in the late-game.

* Lifestealer is able to endure Undying, especially in the laning phase, where Undying is strongest. Feast can offset Decay's strength steal for its percentage lifesteal. Rage delays Undying from stealing strength and can help Lifestealer destroy Undying's Tombstone uninterrupted. As well, none of Undying's abilities pierce magic immunity.

* Storm Spirit is invulnerable during Ball Lightning, allowing him to zip away from any ganking attempts with Rupture.
* Ball Lightning also prevents Bloodseeker from chasing down an injured Storm Spirit, or catching him in Blood Rite.
Additional:
* Storm Spirit is invulnerable during Ball Lightning, rendering Rupture ineffective against him.

* Feast makes it impossible to for Lifestealer to be culled with Culling Blade and also deals high damage to Axe due to his naturally high health.
* However, Berserker's Call and Counter Helix can pierce through the Rage, and if Axe has allies with him against Lifestealer, Lifestealer may go down very quickly.

* Terrorblade has low mobility, which makes it easy for Storm Spirit to kite him.
* Terrorblade gains a lot of agility and gains very low strength, which makes it easy to burst him down with Storm's magical damage.
* All of Terrorblade's abilities are easily avoided by Storm Spirit as he can simply use Ball Lightning, wasting the duration of Metamorphosis, Conjure Image, and Reflection.
* However, if Storm Spirit's Orchid Malevolence is on cooldown or if he doesn't have it, Terrorblade can easily use Sunder and kill a careless Storm Spirit.
Additional:
* Storm Spirit has heavy magic damage that bypasses Terroblade's high armor.
* Ball Lightning can either use to initiates Terroblade from distance or kite Terroblade from using Sunder as he has no source of disable to deal with Storm Spirit outside of Terror Wave from Aghanim's Scepter.

* With Aghanim's Scepter upgraded Infest, Lifestealer can use it on enemy heroes to attack them and disarm them from inside, even if they are spell immune, which can give him the edge over the heroes he's weak against like Ursa, Phantom Assassin, Terrorblade or Troll Warlord.

* Squishy heroes or heroes without hard disables or silences: Shadow Demon, Shadow Fiend, Venomancer, Ancient Apparition etc.

* Heroes with considerable mobility can easily escape from a rolling Pangolier: Anti-Mage, Queen of Pain, Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, moreover, if a player is familiar with how Rolling Thunder works, they can adjust their movement to avoid it entirely and of course outplay the Pangolier player.

* Heroes that have superior mobility that can easily catch up with Mirana even after she used Leap to escape: Anti-Mage, Queen of Pain, Storm Spirit, Riki.

* Heroes with mobility spells can quickly escape from Stroke of Fate or break out of Soulbind: Anti-Mage, Queen of Pain, Morphling, Storm Spirit

* Juggernaut and Lifestealer have abilities (Blade Fury and Rage respectively) that prevent Crystal Maiden from using her spells on them in the early game, before Black King Bar and other magical reduction is even an issue.

Additional:
* Crystal Maiden is an ideal target for Lifestealer due to her poor mobility and low health pool. Lifestealer can usually catch up to her simply by casting Rage, as none of her abilities pierce through magic immunity. Freezing Field can potentially make her even more vulnerable to Lifestealer while under Rage as she is even more immobile while channeling it.
* Lifestealer commonly buys Abyssal Blade, which allows him to cancel Freezing Field, even if Crystal Maiden is spell immune.
* Alternatively, Aghanim's Scepter upgraded Infest combined with Abyssal Blade and with items that provide attack speed which Lifestealer commonly buys allow him to to cancel Freezing Field from within the Crystal Maiden.

* Heroes with spell immunity-granting spells will render Phoenix useless against them, as Phoenix has almost no spell immunity-piercing ability, other than the stun at the end of Supernova: Lifestealer, Juggernaut.

* Heroes that usually build Linken's Sphere as either a core or situational item: Weaver, Medusa, Morphling, Queen of Pain, Storm Spirit, Luna, Naga Siren.

* Heroes with escaping and disjointing abilities can be good against Juggernaut:Anti-Mage Riki, Queen of Pain, Puck, Storm Spirit, Ember Spirit, Slark etc.

* Heroes with burst damage of their own won't be afraid to go toe to toe with Void Spirit, like Ursa, Lifestealer, or Axe.

* Storm Spirit can quickly close the distance with Lina using Ball Lightning. In addition, Ball Lightning can be used as a way to dodge the abilities of Dragon Slave and Light Strike Array
Additional:
* Storm Spirit can quickly close the distance with Lina using Ball Lightning. In addition, Ball Lightning can be used as a way to dodge the abilities of Dragon Slave and Light Strike Array

* Heroes who have most or all their abilities (damage or disable) unable to pierce spell immunity: Keeper of the Light, Lina, Lion, Zeus.

Additional:
* Rage protects Lifestealer from all of Lina's abilities. However, Lina can paritally counter this if played as Carry, a common role for Lina.
* Open Wounds from Aghanim's Shard can severely slow down Lina and allow Lifestealer and his allies to recover themselves by attacking her.
* Aghanim's Scepter upgraded Infest can be used to disarm Lina even if she is spell immune, rendering her unable to maximize the effect of her Fiery Soul and force her to use her abilities more often than intended. And Lina's only way to counter this is with Linken's Sphere

* An isolated Enigma in the early game can be easily killed by Storm Spirit thanks his higher mobility and dueling potential. However, Storm Spirit can be killed when caught by Enigma's full combo, especially if Enigma has Black King Bar.
* Storm can kill all of Enigma's Eidolons relatively quickly without much risk, slowing down Enigma's farming speed, preventing him from split pushing, and giving Storm its considerable bounty, especially if Enigma chooses the Level 25 Talent that gives him more Eidelons.
* Storm can zip through Black Hole stunning Enigma while he's channelling until Enigma buys Black King Bar.

* Enigma lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Enigma finishes his initiation: Faceless Void, Terrorblade, Ursa, Weaver, Broodmother, Slark, Abaddon, Wraith King, Lifestealer.

* Heroes with spell immunity abilities won't be caught inside by Pit of Malice: Juggernaut, Lifestealer.

* Storm Spirit can steal Aegis of the Immortal during Roshan attempts through the Pit, because of his Ball Lightning.
* Ursa has no way to catch a slippery Storm Spirit, as Earthshock's slow will do nothing to stop Storm Spirit from using Ball Lightning.

* With Aghanim's Scepter upgraded Infest, Lifestealer can use it on enemy heroes to attack them and disarm them from inside, even if they are spell immune, which can give him the edge over the heroes he's weak against like Ursa, Phantom Assassin, Terrorblade or Troll Warlord.

* Ball Lightning allows Storm Spirit to easily catch up to Monkey King, destroying a large number of trees, cancelling Tree Dance, and causing Monkey King to be stunned in the process.
Additional:
* Ball Lightning allows Storm Spirit to destroy a large amount of trees, negating Tree Dance. It also makes it easy to avoid Wukong's Command and Boundless Strike.

* Ball Lightning can be used to clear Nature's Prophet's Treants and easily destroys Sprout.
* Electric Vortex prevents Nature's Prophet's escaping using Teleportation.

* Pugna is a very fragile hero who can easily get caught and killed by Storm Spirit's long range initiation.
* This is especially true if he has Orchid Malevolence or Scythe of Vyse.
* Pugna has no disables that can prevent Storm Spirit from escaping.
* Even though Ball Lightning requires high amount of mana, Nether Ward is ineffective since Storm Spirit is invulnerable while using it.
* Storm Spirit's other abilities cost very insignificant amount of mana for Nether Ward to be effective.

* Rage can protect Lifestealer from most of the Silencer's abilities with the exception of Global Silence, as it will still silence if cast while the target is magic immune. However, it will not work if Lifestealer is infesting a unit.
* Silencer is vulnerable to Open Wounds due to his lack of an innate escape.
* Against a carry Silencer, Aghanim's Scepter upgraded Infest can disarm him and allow Lifestealer to attack Silencer from within, even if Silencer is spell immune.
Additional:
* Rage can protect Lifestealer from most of the Silencer's abilities with the exception of Global Silence.
* If Lifestealer can Infest himself on any unit, he can literally avoid being affected by Global Silence.
* Against a carry Silencer, Aghanim's Scepter upgraded Infest can disarm him and allow Lifestealer to attack Silencer from within, even if Silencer is spell immune.
* Open Wounds from Aghanim's Shard can severely slow down Silencer, and allow Lifestealer and his team to heal themselves by attacking Silencer.

* Rage negates Kunkka's X Marks the Spot.
* As a strength hero with high strength gain and very little armor, as well as low agility gain, Kunkka is vulnerable to Lifestealer's Feast and Open Wounds.

* Shadow Demon will have a hard time catching Storm Spirit, as he can get away with Ball Lightning.
* Static Remnant will make quick work of the spawned illusions from Disruption.
* With very high mobility and usually being paired with Orchid Malevolence, he can catch Shadow Demon with ease both in ganks and in teamfights if Shadow Demon has no survivability items.

* Ball Lightning and Electric Vortex will catch Broodmother before she has a chance to retreat, and is able to catch her through the trees.
* Conversely, Ball Lightning also allows him to easily escape Broodmother, as she has no way to prevent him from using it before getting Orchid Malevolence.

* Ball Lightning disjoints an incoming Magic Missile, avoids Wave Of Terror, and allows Storm Spirit to easily escape if he ever gets Nether Swapped.

* Heroes with AoE abilities are a bane to Beastmaster's summons: Storm Spirit, Magnus, Pangolier.

* Storm Spirit has multiple AoE abilities to deal with Phantom Lancer, especially with Aghanim's Scepter.
* Ball Lightning destroys illusions, avoids Spirit Lance, and makes Storm Spirit very hard to catch, even with Phantom Rush.
Additional:
* Ball Lightning with or without the Static Remnant talent allows Storm Spirit to destroy Phantom Lancer's illusions quickly. It is also easy to dodge Spirit Lance with Ball Lightning and makes Spirit Storm very hard to catch even with Phantom Rush.

* Rage protects Lifestealer from all of Techies's abilities. Reactive Tazer's disarm will also not work on Lifestealer under Rage.
* Rage can also be used to trigger Techies's Proximity Mines safely.
Additional:
* Lifestealer's Rage lets him clear Proximity Mines without taking damage, and allows him to hit heroes whom Techies has used Reactive Tazer on.

* Feast deals damage and heals Lifestealer based on the target's maximum HP, which is greatly effective against naturally high HP heroes such as Doom.
* Rage allows Lifestealer to become spell immune to negate the magical damage of Infernal Blade and Scorched Earth.
* Doom has no effective means of escape from Open Wounds and Ghoul Frenzy. This is particularly devastating in the laning stage, where Doom may have to play a much more passive, conservative play style as a result.

* Heroes who have most or all their abilities (damage or disable) unable to pierce spell immunity: Keeper of the Light, Lina, Lion, Zeus.

Additional:
* Rage makes Lifestealer debuff immune and gives him magic resistance which can drastically reduce magical damage from Lion's abilities while also preventing Lion to do anything to him.
* Lion's lack of inner escape and defensive mechanisms increases Ghoul Frenzy effectiveness, since it applies slows upon attacking.
* Lifestealer's physical damage output is strong against Lion's low health and base armor
* Infest can be used to surprise unsuspecting Lion if he tries to take down alone enemy hero. Aghanim's Scepter upgraded Infest can be used to disarm Lion and attack him from inside, even if Lion is debuff immune with the Aghanim's Shard upgraded Mana Drain.

* Squishy heroes or heroes without hard disables or silences: Shadow Demon, Shadow Fiend, Venomancer, Ancient Apparition etc.

* Rage allows Lifestealer to freely attack Nyx Assassin and hunt him down if Vendetta is on cooldown. Nyx Assassin cannot counter Rage with Spiked Carapace because Rage gives Lifestealer spell immunity. And besides Vendetta, Nyx Assassin has no other way of dealing damage to Lifestealer while he is spell immune.
* Open Wounds from Aghanim's Shard allows Lifestealer to severely slow down Nyx Assassin while also allowing his team to recover themselves while attacking Nyx Assassin. Open Wounds can also fester and spread if Nyx Assassin takes enough damage that will trigger the spread while he is affected with Open Wounds.
* Infest combined with an ancient creep makes Nyx Assassin an easy target to surprise with Dust of Appearance or a Gem of True Sight. Aghanim's Scepter upgraded Infest can also allow Lifestealer to infest, disarm and freely attack Nyx Assassin from within. and Nyx Assassin cannot counter this with Spiked Carapace because Lifestealer is invulnerable while attacking the infested enemy hero from within.
* Overall, any attempt for Nyx Assassin to gank and kill Lifestealer will hurt Nyx Assassin more than Lifestealer.
Additional:
* Like with Juggernaut's Blade Fury, Rage allows Lifestealer to freely attack Nyx Assassin and hunt him down if Vendetta is on cooldown. Nyx Assassin cannot counter Rage with Spiked Carapace because Rage gives Lifestealer spell immunity. And besides Vendetta, Nyx Assassin has no other way of dealing damage to Lifestealer while he is spell immune.
* Open Wounds from Aghanim's Shard allows Lifestealer to severely slow down Nyx Assassin while also allowing his team to recover themselves while attacking Nyx Assassin. Open Wounds can also fester and spread if Nyx Assassin takes enough damage that will trigger the spread while he is affected with Open Wounds.
* Infest combined with an ancient creep makes Nyx Assassin an easy target to surprise with Dust of Appearance or a Gem of True Sight. And similarly to Juggernaut's Omnislash and Swiftslash from Aghanim's Scepter, Aghanim's Scepter upgraded Infest can also allow Lifestealer to infest, disarm and freely attack Nyx Assassin from within. And Nyx Assassin cannot counter this with Spiked Carapace because Lifestealer is invulnerable while attacking the infested enemy hero from within.
* Like with Juggernaut, any attempt for Nyx Assassin to gank and kill Lifestealer will hurt Nyx Assassin more than Lifestealer.

* Rage can be used to escape from a Glimpse and to move out of Kinetic Field.
* Infest allows Lifestealer to dodge Glimpse.

* Ball Lightning allows Storm Spirit to close the gap between him and Weaver in no time. Once locked down with certain items, Weaver is extremely fragile to Storm Spirit and his teammates.

* Ball Lightning can escape quickly fear from Focus Fire. Windranger can not reach Storm Spirit although Windrun active catch him.
Additional:
* The high mobility provided by Ball Lightning makes it hard for Windranger to find a good position to land Shackleshot or a full duration of Focus Fire. It can be also used to dodge Powershot.

* With Aghanim's Scepter upgraded Infest, Lifestealer can use it on enemy heroes to attack them and disarm them from inside, even if they are spell immune, which can give him the edge over the heroes he's weak against like Ursa, Phantom Assassin, Terrorblade or Troll Warlord.

* Lifestealer's Rage negates Sand King's spells which do magical damage.

* Storm Spirit is not only a potent Orchid Malevolence carrier, his Electric Vortex provides an additional disable and Overload provides a great slow. When paired with Static Remnant, they can cut through Flame Guard fast.
* Ball Lightning not only provides great initiation upon Ember Spirit from any position anytime, but also helps dodge Sleight of Fist.

* Heroes with magic immune abilities can negate most of Visage's attacks like Pangolier and Lifestealer.
