* Crypt Swarm helps clear treant pushes.
* Silence prevents Nature's Prophet from using Sprout or Teleportation.
* Exorcism kills all treants.
Additional:
* Exorcism can quickly kill any Treants or Necronomicon units. Silence also prevents him from using Teleportation to escape or Sprout to lock you down.

* Doom can eats Nature's Prophet's treants with Devour and gains lots of gold.
* Doom usually buys Radiance or using his Scorched Earth deals a lot of damage to Nature's Prophet if they stand close to his Treants, as well as killing all of his Treants and getting lots of gold.
* Doom can pick up several different abilities from neutral creeps using Devour, some of which can be annoying to Nature's Prophet:
* 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 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.

* Because Timbersaw relies heavily on his spells to deal damage, Silence can easily disable him in a team fight.
* Exorcism's spirits do not count as regular attacks, and will not add stacks of Reactive Armor.

* Quas-Exort Invoker is also a good matchup due to the fact he has no Wex to run faster due to the movement impairment on his stealth. The Forge Spirit and Cold Snap combo doesn't harm her as well since you can drain Invoker's HP with Spirit Siphon which forces him to retreat.
* Silence also prevents Invoker from using Invoke or casting his main spells temporarily. There is no way Invoker can block it unless he has Eul's Scepter of Divinity to cyclone himself or has help from allies.

* 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.

* Spirit Siphon and Exorcism can damage through his Resonant Pulse shields.
* Silence can prevent Void Spirit escape or contributing much in fights.

* 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.

* 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.

* High health heroes like Pudge and Undying gain strength by using abilities. Focusing them with Spirit Siphon can let you heal more health and deal more damage to them.

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

* Any heroes with stuns or silences: Death Prophet, Lion, Shadow Shaman, Skywrath Mage

* 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.

* In the same vein, heroes with silences — especially with the AoE ones like Death Prophet's Silence — can also prevent Crystal Maiden from being able to impact a fight.

* Death Prophet abilities disables Earthshaker's Blink Dagger.
* Silence can be used to silence Earthshaker after he blinks in, preventing him from executing his combo.

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

* 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.

* In early to mid stage, Silence is also a great way to counter escape oriented heroes such as Anti-Mage, Queen of Pain, and Phantom Assassin to prevent them from escaping, provided that they don't have any basic dispels.

* Heroes with silencing abilities can be particularly deadly when Slark is trying to escape: Silencer, Death Prophet, Puck, Doom

* Heroes with silencing abilities can be particularly deadly when Slark is trying to escape: Silencer, Death Prophet, Puck, Doom

* Because all of Warlock's abilities are active abilities, silences can make his impact in fights minimal. Be cautious of heroes that carry silences like Death Prophet, Puck, and the aforementioned Silencer.

* Supports with useful teamfight or contribution spells will be helpless against Doom: Dazzle, Oracle, Warlock.

* Faceless Void relies on Time Walk for mobility and survivability but he can be prevented from utilizing it through Doom.
* Doom has a high cooldown duration for every ability except Infernal Blade, so he is not significantly affected by Time Dilation.

* Infernal Blade deals scaling damage and is useful against high health targets such as Bristleback.
* Doom disables Bristleback's low cooldown abilities, preventing him from triggering Warpath. With Aghanim's Scepter, it also breaks Bristleback's passive, rendering him more vulnerable.
Additional:
* Infernal Blade deals scaling damage and is useful against high HP targets such as Bristleback.
* If Doom gets an Aghanim's Scepter, he can disable Bristleback, taking away much of his durability.
* Doom prevents Bristleback from casting his two low cooldown abilities, which then prevents him from utilizing Warpath.

* Heroes that can instantly kill creeps greatly reduce the effectiveness of Chen's converted army: Lifestealer, Doom, Mirana, Clinkz.

* Silence will prevent Chen from activating Hand of God.
* Crypt Swarm and Exorcism can clear Chen's creeps and heavily damage Chen.
* Spirit Siphon heavily damages Chen and slows him, while healing Death Prophet.

* Exorcism kills Primal Split's units very quickly.

* Infernal Blade's damage is calculated by percentage of maximum health, meaning that it will hurt Spectre more than most normal attacks, negating some of her tankiness.
* Doom can pick up several different abilities from neutral creeps using Devour, some of which can be annoying to Spectre.
* Mud Golem, Dark Troll Summoner, Harpy Stormcrafter, Satyr Mindstealer or Satyr Tormenter are good examples.
* Doom makes Spectre less disruptive. Combined with Aghanim's Scepter, it will break Spectre passive skills, reducing her potential in teamfights.

* 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.

* Silence will prevent Queen of Pain from using Blink to escape or chase.
* If Queen of Pain uses Blink to close the gap to Death Prophet, Death Prophet will be in range for Spirit Siphon and typically gain an advantage over Queen of Pain.

* Exorcism's ghosts will automatically clear all Proximity Mines revealed when Death Prophet walks near them, provided that the ghosts do not have a specific target at that time.

* 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.

* Doom makes Ogre Magi less disruptive.
* Infernal Blade effectively negates Ogre Magi's tankiness.
* With Aghanim's Scepter he can disable Multicast.

* 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.

* Doom makes Ursa less disruptive, and it cannot be dispelled with Enrage upgraded with Aghanim's Scepter.
* Aghanim's Scepter upgraded Infernal Blade can break Fury Swipes, negating much of his damage output.

* 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.

* 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.

* 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.

* 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.

* Death Prophet's Silence allows her to prevent Bounty Hunter from escaping with Shadow Walk.
* If Bounty Hunter cannot escape with Shadow Walk while affected by Silence, she will be able to burst him down with Crypt Swarm and Spirit Siphon.

* Doom pierces spell immunity and can prevent Enigma from casting any spells or using items until the duration of the spell depletes, as well as damaging him over time. This can however, be blocked by a Linken's Sphere.
* 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.

* Heroes with break can disable Untouchable for a while: Doom and Shadow Demon (via Aghanim's Scepter), Viper

* 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.

* 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.

* 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'.

* In early to mid stage, Silence is also a great way to counter escape oriented heroes such as Anti-Mage, Queen of Pain, and Phantom Assassin to prevent them from escaping, provided that they don't have any basic dispels.

* As a spellcaster, silences will nullify him entirely. Some notable examples are Death Prophet, Drow Ranger, Bloodseeker, Disruptor and many others.
* Doom, as usual, fits this description nicely.

Additional:
* His low mobility tends to make him an easy target for Spirit Siphon and the ghosts from Exorcism.
* His magical nukes can also be healed with Spirit Siphon.
* Silence is great against any spellcaster, and Zeus is no exception to this.

* 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.

* Lone Druid during True Form and the Spirit bear has high HP, meaning Spirit Siphon can be very effective against them since they deal percentage damage

* Death Prophet is a terrible Flaming Lasso target if Exorcism has already been used, since it can still damage Batrider and his teammates, but if Batrider manages to Lasso her before that, it can lead to Death Prophet being quickly burst down.

* Windranger heavily relies on her abilities for any form of tactical advantage and damage. A well timed silence will make her useless: Puck,Silencer, Death Prophet, Skywrath Mage, Drow Ranger, Earth Spirit, Grimstroke.

* A couple of long-range heroes with excellent laning like Mirana, Lina, Necrophos, Death Prophet. The key to success is sticking together and attacking Luna whenever she enters the range, without even giving Luna a chance to retaliate. Multiple long-range heroes is a reason to pick another hero.

* Silence (and mana burns) will be a persistent problem for Phoenix, as it is heavily reliant on its abilities whether defensively or offensively, so heroes like Death Prophet, Skywrath Mage, and even Nyx Assassin must be closely observed to prevent being shut down by these heroes.
* Hexes are a greater threat to Phoenix as they also disable items, preventing Phoenix from dispelling the debuff on its own.

* Heroes with good counter-push abilities to clear creep waves can hinder Jakiro's early pushing ability: Death Prophet, Sniper, Tinker, Windranger.

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

* Heroes who can silence will shut down Dark Willow entirely: Death Prophet, Silencer, Drow Ranger

* Heroes with silences and hard stuns such as Doom, Silencer, and Lion can keep Mirana from Leaping away.

* With 4 active abilities, Shadow Shaman is weak against silencing foes such as silencer, Drow Ranger and Death Prophet.

* Heroes that can punish aggressive heroes, such as: Leshrac, Shadow Demon, Pugna, Death Prophet.

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

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

* 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.

* 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.

* Heroes that are hard to gank: Axe, Death Prophet, Phantom Lancer

* Supports with useful teamfight or contribution spells will be helpless against Doom: Dazzle, Oracle, Warlock.

Additional:
* Doom can completely shut down Dazzle through Doom, as it prevents him from casting his abilities and, by extension, gaining Bad Juju stacks.

* High health heroes like Pudge and Undying gain strength by using abilities. Focusing them with Spirit Siphon can let you heal more health and deal more damage to them.

* Supports with useful teamfight or contribution spells will be helpless against Doom: Dazzle, Oracle, Warlock.

* An Aghanim's Scepter-upgraded Infernal Blade can be useful against heroes with troublesome passive skills: Phantom Assassin, Enchantress, Huskar, Underlord.

Additional:
* Infernal Blade does damage based on percentage health, and is useful against high health pool hero like Underlord
* Doom can prevent Underlord from spamming his abilities and most important is prevent him from using Dark Rift to escape
