* All assassin-type carries in a one against one situation: Meepo, Phantom Assassin, Riki, Ursa. Luna's only chances are that she buys Ethereal Blade or Black King Bar to gain a slight edge against them, or both items if necessary.

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

* Heroes with blind of some sort can be a bad choice for Monkey King to go on: Broodmother, Riki, Keeper of the Light.

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

* Heroes with abilities that blind or cause Legion Commander to miss will prevent her from winning Duels: Arc Warden, Keeper of the Light, Riki, Tinker

* Heroes with high armor like Dragon Knight, or with abilities to cause attacks to miss like Phantom Assassin, Riki and Tinker will be hard to deal with, as Clinkz relies almost entirely on physical attacks.

Additional:
* Smoke Cloud prevents the use of Death Pact, Searing Arrows and Skeleton Walk, so Clinkz can neither defend himself against Riki nor fight back effectively.
* It's hard to gank Riki as Clinkz has to find him first.

* 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 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 with abilities that can lock down Terrorblade and prevent him from using Sunder: Bane, Batrider, Earthshaker, Elder Titan, Faceless Void, Invoker, Legion Commander, Mars, Primal Beast, Riki, Shadow Shaman, Silencer, Vengeful Spirit, Void Spirit.

* 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.

* Sniper has no natural escape and relies on his range and slows to keep himself safe, which Riki can bypass with Blink Strike and quickly deplete his miniature HP pool.

* 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.

* Smoke Screen prevents Dark Willow from using her abilities, rendering her defenseless and unable to deal any serious damage.
* Blink Strike lets Riki jump past Bramble Maze.

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

* 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.

Additional:
* Chen is basically Riki's natural prey: he has little HP, low armor and relies on his persuaded creeps to fight, which in most situations will not save Chen from Riki. Just be wary of {U:Centaur Conqueror}, who can stun Riki outside of Smoke Screen and ruin his attempt at Chen's life.

* 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 silence: Death Prophet, Riki, Drow Ranger.

* 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).

* Heroes with silences: Puck, Doom, Riki.

* 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 a high degree of mobility and invisibility are hard to catch with Meat Hook: Ember Spirit, Riki, Clinkz, Queen of Pain.

* 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.

* Heroes with damage-increasing passive abilities, such as Viper and Riki, will usually kill Silencer in a short time before he even has time to set up his abilities.

* 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.

* Riki with Tricks of the Trade
* Heroes that can dodge Glimpse:
* Puck with Phase Shift
* Riki with Tricks of the Trade
* Phantom Lancer with Doppelganger
* Ember Spirit with Sleight of Fist and Activate Fire Remnant
* Chaos Knight with Phantasm
* Naga Siren with Mirror Image
* Tusk with Snowball
* Juggernaut with Omnislash
* Brewmaster with Primal Split
* Lifestealer with Infest
* Phoenix with Supernova

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

* Earthshaker must be careful not to use Blink Dagger or Aghanim's Scepter upgraded Enchant Totem to blink into Riki's Smoke Screen or Night Stalker's Crippling Fear, as these field effects will instantly silence Earthshaker and prevent him from initiating.

* 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.

* Smoke Screen combined with Diffusal Blade leaves Arc Warden effectively useless for a while as he struggles to escape the silence with low mobility.
* With Arc Warden's low mobility, Tricks of the Trade often deal decent damage to him before he moves out of it.

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

* Blink Strike gives bonus backstab damage and can bypass Bulwark. Defensively, it could be used to teleport away from Mars, especially while inside Arena of Blood.
* Smoke Screen can interrupt Mars' skill combos, especially when cast inside Arena of Blood.
* Tricks of the Trade can be used to evade Mars' skills, which have a slight delay to them. It could also be used to buy himself time while trapped inside of Arena of Blood.
Additional:
* Bulwark is generally irrelevant against Riki as he primarily deals bonus damage from behind.

* 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.

* 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.

* 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.

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

* Riki's Smoke Screen can make it hard for Spectre to escape or burst down Riki with auto attacks.
* Riki can build Aghanim's Scepter and jump inside an allied carry or offlane tank with Tricks of the Trade to do a lot of damage to Spectre while completely avoiding Dispersion.
* Riki is great at destroying supports which are often needed to keep Spectre safe until she comes online. He can take them down quickly in team fights, which will leave Spectre alone against your whole team, a fight that she will most likely not win.
* While on Tricks of the Trade, Riki does not take damage from Dispersion.

* 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.

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

* Smoke Screen effectively disables Crystal Maiden's channeling spell: Freezing Field.
* Due to her low health and armor throughout the game, Riki can kill her easily.

* 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.

* 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.

* Riki has high damage and invisibility, meaning he can easily gank Rubick and kill him before Rubick has the chance to react.
* Cloak and Dagger renders Riki invisible, which makes his spells hard to steal if not being initiated.
* Similar to Clinkz, Rubick has to buy a large amount of Sentry Wards to keep track of Riki due to Cloak and Dagger, preventing Rubick from getting better items.

* Smoke Cloud prevents Queen of Pain from using any of her offensive and defensive spells, rendering her unable to effectively react to Riki's attack.
* It's easy to dodge Sonic Wave by using Blink Strike & Tricks of the Trade.

* Blink Strike gets Riki close to Drow Ranger and disable Marksmanship.
* Cloak and Dagger allow Riki stay close to Drow Ranger without her noticing him, which allows him to disable Marksmanship.
Additional:
* With Blink Strike, Riki can get close to Drow Ranger and disable her Marksmanship, and Smoke Screen will prevent her from using Gust.

* 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 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.

* Without Dust of Appearance or Sentry Wards, Riki is able to silence Witch Doctor with Smoke Screen, and is likely to build a Diffusal Blade, leaving Witch Doctor without mana to cast Voodoo Restoration, as well as Skull Basher to interrupt Death Ward.

* 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.

* Due to his low health and armor, Riki can easily kill Skywrath Mage.
* Smoke Screen prevents Skywrath from using all of his abilities, as he does not tend to buy Black King Bar.
* However, Skywrath Mage can easily kill Riki if he manages to root Riki with Rod of Atos or Gleipnir, followed by Dust of Appearance, Ancient Seal and Mystic Flare.

* 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.

* 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.

* 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.

* 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.

* Cloak and Dagger makes Sven unable to detect where Riki is until he shows or his team provides detection.
* Smoke Screen will make Sven miss attacks before he has his Black King Bar.

* Riki is known for being a successful support killer, something Shadow Shaman is very vulnerable to.
* Smoke Screen is particularly devastating to Shadow Shaman. With neither his various disables nor a solid health pool Shadow Shaman is usually dead. This forces Shadow Shaman to buy a Force Staff if he finds himself in this scenario and buy Sentry Wards if you have the money.

* Riki is a natural Diffusal Blade carrier, and it doesn't help that he's easily capable of sneaking up on Wraith King due to Cloak and Dagger.
* Riki can use Smoke Screen on top of Wraith King as he is reincarnating, making him a sitting duck for his second life. In addition, the blind prevents Wraith King from landing critical hits from Mortal Strike.
* Wraithfire Blast is quite predictable, and if Riki can react fast, he will disjoint it with Tricks of the Trade. There is also a chance he will become invisible again as the projectile travels, disjointing it.

* 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.

* Riki and Disruptor: Smoke Screen and Static Storm, respectively, can be thrown wherever Puck used Phase Shift, making Puck an easy target if it doesn't have Blink Dagger or is on cooldown. Puck is also very susceptible to Riki's high attack damage when attacking from the back. Glimpse also prevents Puck from escaping altogether.

* 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 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.

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

* Riki is another good hero to shutdown Death Prophet with Diffusal Blade as his core item. His Smoke Screen stops her from initiating and casting spells.

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

* 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

* Riki can potentially catch an Enigma out of position and prevent him from properly blinking and initiating, thanks to Cloak and Dagger.
* Before Enigma gets his Black King Bar, Smoke Screen can be used to cancel Black Hole. After Enigma gets Black King Bar, Riki can also cancel Black Hole with Abyssal Blade, which is a common item built on him.
* Tricks of the Trade renders Riki hidden and invulnerable, which in combination with Abyssal Blade allows Riki to cancel Black Hole with little to no worries of getting caught in it.
* Enigma's fragility during all stages of the game makes him extremely prone to Riki's ganking.

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

* Riki: Smoke Screen can prevent Lone Druid from using True Form and Savage Roar, additionally it cause the spirit bear to miss on attacks which reduce the chances of getting rooted from it, with diffusal Blade, he can keep Lone Druid or the Spirit Bear inside the Smoke.

* Riki can detect early Roshan attempts because of Cloak and Dagger if he frequently checks the Pit.
* Ursa cannot Enrage when in Smoke Screen (Black King Bar will help though).
* Even if Ursa gets vision over him, Riki can Blink Strike away or use Tricks of the Trade after Ursa's initiation to avoid all Fury Swipes damage until Earthshock's slow is gone.
Additional:
* Riki can detect early Roshan attempts because of Cloak and Dagger if he frequently checks the Pit.
* Ursa cannot Enrage when caught in Smoke Screen and will miss his attacks (although Black King Bar will help with this issue).
* Even if Ursa gets vision over him and initiates with Earthshock, Riki can Blink Strike away or use Tricks of the Trade after Ursa's initiation to avoid Fury Swipes' damage until Earthshock's slow is gone.

* 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 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.

* 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.

* Smoke Cloud prevents Storm Spirit from using any of his offensive and defensive spells, rendering him unable to effectively react to Riki's attack.
Additional:
* Smoke Screen prevents Storm Spirit from using his abilities once inside the radius. Riki can utilize this ability to allow his team to fight around Smoke Screen so that Storm Spirit cannot spam his spells to proc Overload.

* 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.

* Riki usually buys Diffusal Blade to initiate, which renders Enchantress' movement speed useless, and is usually followed with Smoke Screen.
* Riki can effectively hit Enchantress by Tricks of the Trade alongside with Diffusal Blade and Smoke Screen's initiation. For a hero like Enchantress, 3 to 4 hits from Riki is a big deal, unless Enchantress built Force Staff earlier.

* Because Templar Assassin does not have escape potential in lane, any support hero with roaming potential and a Dust of Appearance can be great at shutting her down early game: Earth Spirit, Spirit Breaker, Tusk, Bounty Hunter, Riki, Warlock.

* Heroes with invisibility: (Riki, Clinkz, Nyx Assassin.

* Heroes with abilities or items that can silence or disable Anti-Mage for long periods of time will prevent him from Blinking away: Lion, Silencer, Shadow Shaman, Grimstroke, Witch Doctor, Riki, Faceless Void, Skywrath Mage, Puck.

Additional:
* Anti-Mage can use neither Blink nor Manta Style to escape from Smoke Cloud.
* Even if he activates a Black King Bar, his Manta Style illusions will still be blinded by Smoke Cloud.
* Riki has a very small mana pool and generally doesn't buy many items that increase it, making Mana Void ineffective.

* Heroes that can gank Shadow Fiend in the early game: Earth Spirit, Nyx Assassin, Riki, Spirit Breaker.

* 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.

* Riki can get on top of Ancient Apparition very easily with Blink Strike. This can also double as a way to dodge Ice Blast, along with Tricks of the Trade.
* Ancient Apparition will frequently resort to casting Ice Blast right before dying. Smoke Screen can be used to prevent this, stopping Ancient Apparition from having any impact.

* Smoke Cloud prevents Shukuchi and Time Lapse, leaving Weaver helpless against Riki.
* The Swarm is ineffective against Riki because invisibility instantly removes the beetles.

* 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.

* Warlock is a very strong hero when positioned correctly, and his long cast range helps him with this. However, some heroes might disrupt or sneakily pass through his allies and deal with him, preventing him from doing his job. Such heroes include Chaos Knight, Spirit Breaker, Riki, and more.

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

* 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.

* Frail heroes who lacks mobility: Crystal Maiden, Enigma, Dark Willow, Vengeful Spirit.

* 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.

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

* With Smoke Screen, Riki will silence and catch Medusa in a surprise with high miss chance flushing her from positions easily in team fights.
* He can deal a huge amount of damage through Cloak and Dagger, even through Mana Shield.
