* Doom disables the toggling of Rot and, if cast at the right time, may leave Pudge with a potentially lethal health drain.
* Doom's naturally high health, strength gain and damage output makes him a poor target for Pudge.
* The damage of Doom's Infernal Blade scales with the target's maximum health, which is particularly effective against Pudge due to his naturally high health and further health granted by stacks of Flesh Heap.
Additional:
* Infernal Blade deals high damage to Pudge due to his high strength grow with Flesh Heap.
* Using Doom with timing against Pudge who had just activated Rot would usually kill him.

* The lifesteal of Feast scales accordingly to the 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 completely negate magic damage, therefore rendering the damage of Rot and Dismember null.
* Pudge's plentiful health makes him an ideal target for Open Wounds.

* Doom completely takes Invoker out of a team fight, a hero who relies on using abilities and items to contribute.
Additional:
* Doom is a good way to shut down Invoker, preventing from casting spells and using items for a lengthy time, thus forcing him to invest on Linken's Sphere.

* Rage protects Lifestealer nearly from all of Invoker's spells.
Additional:
* 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.

* Tinker is heavily reliant on casting his spells and Doom can disable all of his abilities and items. An Aghanim's Scepter only makes it harder for Tinker to survive.
Additional:
* Tinker is heavily dependent on active abilities and Doom prevents him from using any of them.

* 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.
Additional:
* Lifestealer's Rage makes him immune to all of Tinker's damage and debuffs.
* Lifestealer can infest any mobile hero (teams usually pick one against Tinker), which ensures that Tinker will die if he is caught.

* Infernal Blade's damage is calculated by percentage of maximum health, meaning that it will hurt Axe more than most normal attacks, negating some of his tankiness. With Aghanim's Scepter, Counter Helix is also disabled, making him effectively useless for a lengthy duration.
* Doom can pick up several different abilities from neutral creeps using Devour, some of which can be annoying to Axe.
* Mud Golem, Dark Troll Summoner, Harpy Stormcrafter, Satyr Mindstealer or Satyr Tormenter are good examples.
* Doom's naturally low attack speed makes Counter Helix less likely to proc.
* Doom makes Axe less disruptive, preventing him from using his skills or items.
Additional:
* Infernal Blade deals scaling damage and is useful against high HP targets such as Axe.
* Doom has low attack speed because of his high Base-Attack-Time, poor agility gain and limited attack-speed granting items which are commonly built. This means Doom will trigger Counter Helix less often and thus is an unideal target for initiation.
* Doom has naturally high HP so it takes longer for Doom to be brought down to the killing threshold of Culling Blade.
* Axe is highly reliant on his abilities and items to be effective during a fight. Without the usage of Berserker's Call and Blink Dagger, Axe offers very little in the way of damage.

* Feast's lifesteal makes it nearly impossible for Axe to initiate and bring Lifestealer's health low enough for Culling Blade, even with many procs of Counter Helix.
* Feast's damage is calculated as a percentage of health, turning Axe's high health against him. This allow Lifestealer to hit Axe much harder than most other heroes.
Additional:
* Feast makes it impossible to put Lifestealer's health for a Culling Blade and also deals high damage to Axe due to his naturally high health.
* However, Lifestealer's Rage can be pierced by Berserker's Call.

* Doom makes Ogre Magi less disruptive.

* With Aghanim's Scepter he can disable Multicast.

* Ogre's as hero with great durability and high health is great target for Lifestealer in any stage of the game, thanks to Feast.

* 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.

* Silencer's Global Silence and Doom's Doom makes Earthshaker temporarily useless.

* Doom is effective against every hero, and Void Spirit is no exception. Being unable to cast spells or items during fights for 16 seconds nullifies his impact entirely.
* Doom has a very versatile build and can consume creeps which has abilities that can stun or provide additional magic resistance.
* Doom's high strength gain and versatility in items can be effective against Void Spirit's magical damage.

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

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

* Heroes with abilities that break Berserker's Blood, lowering Huskar's attack speed and health regeneration: Doom, Shadow Demon, Viper.

* Doom alone can easily pick off Crystal Maiden since she is fairly fragile, even with using only basic attacks, Infernal Blade, and Scorched Earth.
* Doom prevents her from using any abilities in a fight, making her impact negligible.
* Devour allows Doom to acquire a stun, allowing him to cancel Freezing Field without having to use Doom.

* 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.

* Slark, Lifestealer, Morphling and such with a good escape mechanism are a nuisance to deal with in the early-game.

* Arc Warden relies on items and abilities, as well as his {U:Tempest Double}, to deal damage to enemies. Doom effectively denies that and makes Arc Warden useless in fights.

* Rage completely negates all of Nyx Assassin's abilities except Vendetta, while Open Wounds allow him to quickly close the gap.
* Infest combined with an ancient creep makes Nyx Assassin an easy target with Dust of Appearance or a Gem of True Sight.

* A well-timed Doom prevents Nyx Assassin escaping with Vendetta and does not allow him to disengage with Spiked Carapace.
* Doom's high HP easily shrug off Nyx Assassin's burst damage and fend him off.

* Rage ignores all of Gyrocopter's magical attacks.
* Open Wounds makes it hard for Gyrocopter to get away.
* Feast helps Lifestealer out-damage Gyrocopter at close range.

* Rage allows him to dispel Blinding Light from himself.
* Open Wounds allows him to slow and kill Keeper of the Light.

* 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.

* Rage provides spell immunity to Lifestealer and thus nullifies all of Lion's abilities.
* Open Wounds allows Lifestealer to easily catch Lion out and prevent him from escaping.

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

* Lifestealer's Rage lets him clear Remote Mines and Proximity Mines with proper vision.
Additional:
* Rage protects Lifestealer from all of Techies' magic damage and disables and dispels Stasis Trap's debuff .
* Usually teams will have a hard time pushing high-ground against Techies, but Lifestealer can just pop Rage and walk uphill without fear of Techies.

* Doom can stop Death Prophet from casting spells, which makes her useless during team fights if she didn't cast Exorcism before the fight. Furthermore, Doom can use Scorched Earth to chase after her.

* Doom shuts down Timbersaw completely, negating his mobility and preventing him from doing any damage.
* Infernal Blade can stun Timbersaw several times in a fight, potentially interrupting Timber Chain. It also breaks Reactive Armor's passive bonuses from Aghanim's Scepter.
Additional:
* Infernal Blade deals scaling damage and is useful against high HP targets such as Timbersaw.
* Timbersaw is extremely reliant on his abilities to be effective during a teamfight - both for mobility, damage and crowd control. Timbersaw offers very little impactful right-click damage, and thus Doom is particularly crippling against this hero.
* Additionally, when upgraded with Aghanim's Scepter, Infernal Blade breaks Reactive Armor, which effectively removes the durability which Timbersaw is commonly known for.

* 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.

* Doom prevents Storm Spirit from using all of his abilities and items, rendering Storm Spirit useless in a fight.

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

* Rage protects Lifestealer from all of Lina's abilities (except an upgraded Laguna Blade).
* Open Wounds is great to keep Lina in place because she has no abilities to help her escape.

* Doom shuts down Anti-Mage's escape capabilities with Blink. The ability also deals pure damage, which ignores the protection from Counterspell.
* If Doom has Aghanim's Scepter, Infernal Blade can hit Anti-Mage loses his Mana Break and Counterspell, weakening both his offense and defense.
* Doom's low mana pool causes him to take little damage from Mana Void.
Additional:
* Doom prevents Anti-Mage from maneuvering around a fight or escaping from an initiation using Blink. Additionally, Doom deals pure damage, which is not affected by Counterspell. This can quickly whittle away Anti-Mage's naturally poor health pool.
* Be careful when using Doom as a well-timed Counterspell can block and reflect it back against Doom himself.
* An Aghanim's Scepter upgraded Infernal Blade will also disable Mana Break and Counterspell, which makes Anti-Mage significantly less effective in fights and more susceptible to the high magical damage of Doom's abilities and any allies'.

* Infernal Blade deals scaling damage and is useful against high HP targets such as Elder Titan.
* Doom has very low base armor and naturally high HP, so he isn't significantly affected by Natural Order.

* Infernal Blade deals scaling damage and is useful against high HP targets such as Tidehunter.
* If Doom gets an Aghanim's Scepter, he can also disable Kraken Shell, reducing his survivability and tankiness.
* Doom prevents Tidehunter from casting his Gush, Anchor Smash and Ravage, making him useless in team fights.

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

* Scorched Earth can be used to engage Visage while removing Gravekeeper's Cloak charges.
* Infernal Blade will deal tremendous amounts of damage over time due to Visage's high health pool.
* Doom completely nullifies Gravekeeper's Cloak and prevents Visage from casting spells.

* 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.

* 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.

* Mud Golem, Dark Troll Summoner, Harpy Stormcrafter, Satyr Mindstealer or Satyr Tormenter are good examples.
* Doom makes Spectre less disruptive.

* Any heroes with silences can negate the majority of Outworld Devourer's damage output: Death Prophet, Night Stalker, Drow Ranger, Doom .

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

* The general opinion that Doom can counter Ember Spirit with his Doom is a misconception, as Doom has a long cast animation, so an attentive Ember Spirit can easily dodge it if he has a Fire Remnant nearby. Doom is still an extremely effective early ganker however, as his Scorched Earth and Infernal Blade damage can quickly overwhelm Flame Guard's magic damage absorption, leaving Ember Spirit with no protection against them. Additional skills that Doom can get from Neutral creeps can also help bully Ember Spirit early. Shadow Blade or Blink Dagger on Doom can also help, providing a good way to apply Doom on Ember Spirit.

Additional:
* Ember Spirit cannot use his Activate Fire Remnant while Doomed to escape from Doom.

* Doom, Disruptor with Aghanim's Scepter, and hex abilities all prevent item usage, which is a severe problem for Phantom Assassin as it prevents her from using Black King Bar, the one item that helps protect her against the aforementioned dangers. Doom and Shadow Demon with Aghanim's Scepter also disables Phantom Assassin's Evasion and Critical Strike, removing much of her damage and survivabaility.

* Besides Lone Druid and Meepo, Doom is potentially good versus every hero since Doom will render any hero helpless for a prolonged 15 seconds. This is particularly true for fragile heroes that heavily rely on mobility to stay alive.

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

* Mud Golem, Dark Troll Summoner, Harpy Stormcrafter, Satyr Mindstealer, Satyr Tormenter and etc. are good examples.
* Doom and a ministun from Infernal Blade's prevents Nature's Prophet from escaping with Sprout and Teleportation.

* Doom has several disable abilities to choose from jungle creeps (e.g. War Stomp, Ensnare) to deal with Shadow Fiend who lacks escape abilities.
* When Doom combines creep abilities with Scorched Earth, Infernal Blade, and Doom, Shadow Fiend most likely will die as he cannot use Shadowraze and Requiem of Souls to protect himself, and also cannot even flee by using Shadow Blade or Blink Dagger.
* Although Shadow Fiend has a high physical damage output, Doom has a large health pool to survive it, meaning Doom's combo with high magical damage output will shutdown Shadow Fiend first.
* Doom usually buys Radiance to improve his damage, making his nuke combo more deadly to Shadow Fiend. The blind also prevents Shadow Fiend from landing his attacks often.

* Doom will make Abaddon unable to use Mist Coil, Aphotic Shield, and the active component of Borrowed Time, which means his allies could be easily disabled or killed.

* An Enigma with a Helm of the Dominator can potentially feed his dominated creeps to Doom's Devour, giving Doom the abilities and benefits instead.

* Scorched Earth deals damage to Clinkz during Skeleton Walk.
* Doom shuts down Clinkz entirely, as it prevents him from casting any of his spells and contributing a large amount of damage in teamfights.
