Doom
* Lone Druid is essentially two heroes. Dooming one over the other still leaves Lone Druid or his bear able to do their job during a fight. Additionally, Lone Druid is not hindered as much as other heroes by the silence and mute of Doom since the hero relies more on attacks than abilities.
Additional:
* Doom will be very hestitant to use 
Doom on the Spirit Bear, and using it on Lone Druid himself will not stop the bear from attacking him especially if True Form has already been used.
* 
Devour does not work on the Spirit Bear and pushes the lane so Lone Druid can safely farm under tower.
Ember Spirit
* Lone Druid becomes unkillable and impenetrable for Ember Spirit on the central line, as it has a huge reserve of health from the 
Summon Spirit Bear and a large regeneration from 
Spirit Link, which is why 
Sleight of Fist practically does not break through either one or the other on the line, and Lone Druid at this time can easily expel Ember Spirit from the line, push and gain gold and level
* 
Entangling Claws and 
Savage Roar abilities completely disable Ember Spirit's ability to dodge abilities or get out of an unpleasant fight for him on 
Fire Remnant, which can give the Lone Druid team the opportunity to kill him

Doom
* Besides 
Lone Druid and 
Meepo, Doom is potentially good versus every hero since Doom will render any hero helpless for up to 16 seconds. This is particularly true for fragile heroes that heavily rely on mobility to stay alive.
Doom
* Wraith King has three passive abilities and only a single active ability, so Doom does not hinder him significantly.
* Doom expires upon death, so it is effectively removed after 
Reincarnation activates.
Additional:
* Even if he is Doomed, Wraith King can tear down Doom with physical attacks, and can still reincarnate as long as it is off-cooldown.
Doom
* 
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.
Doom
* Any heroes with low mana pools will die quickly or even instantly to Sanity's Eclipse: 
Doom, 
Phantom Assassin, 
Troll Warlord.
Ember Spirit
* The pure damage provided by 
Arcane Orb is a great addition for killing Ember Spirit.
* 
Astral Imprisonment fully negates all magic damage of Flame Guard and Searing Chains and will temporarily save himself from Sleight of Fist's physical damage, and Ember Spirit is not a hero that can counter these skills.
Doom
* Any heroes with silences can negate the majority of Outworld Destroyer's damage output: 
Death Prophet, 
Night Stalker, 
Drow Ranger, Doom .
Doom
* Doom does not disable 
Mana Shield. As such, Doom's damage is largely mitigated by her mana shield. Additionally, Medusa is not reliant on her abilities to be effective during a teamfight, making Medusa an unproductive hero to target.
* Medusa is an ideal 
Linken's Sphere carrier. Should one be purchased, and without any additional disables, Doom may find that few opportunities exist to effectively lockdown, disable, and kill Medusa.
Doom
* Drow Ranger can be difficult to get on top of, thanks to her 
Frost Arrows and 
Gust. With these two abilities, Drow Ranger is able to effectively 'kite' Doom and minimize his impact during team fights and laning stage.
* Much of Drow Ranger's effectiveness comes from her passive 
Marksmanship, which is not disabled by Doom.
Ember Spirit
* Using 
X Marks the spot Kunkka can prevent Ember Spirit from escaping with Activate Fire Remnant, until he purchase 
Eul's Scepter of Divinity or Linken's Sphere.
Ember Spirit
* Lion possesses two strong disables in 
Earth Spike and 
Hex and heavy magic burst with 
Finger of Death which help lock him down and prevent him from escaping with Activate Fire Remnant. When getting his 
Blink Dagger Lion can punish Ember Spirit's overextension immediately, or initiate a fight on him with disables.
Doom
* Whenever Doom casts his ultimate, Centaur Warrunner can cast Stampede and allow the Doomed hero to run away, wasting Doom's ultimate.
Additional:
* 
Stampede can be used to free an ally from the grasp of Doom. Without any means of effective lockdown, kills can be difficult to secure when against an enemy Centaur Warrunner. Also, Centaur's tendency to have lots of health and HP regen tend to help counter Doom.
Doom
* Due to Doom's naturally high health, strength gain and common itemization for durability, 
Heartstopper Aura is particularly effective. The health loss is also large enough that, throughout all stages of the game, the aura effectively neuters the health regeneration granted by Devour.
* Necrophos can help to keep both himself and his allies alive during Doom through his natural regeneration granted by Heartstopper Aura (which is not disabled by Doom), or in the case of an ally, through his 
Death Pulse. Additionally, Necrophos is an ideal 
Mekansm carrier. Should one be bought, kills against Necrophos' team can be difficult to secure due to the damage-over-time nature of Doom and his abilities.
* Doom typically wants to be a hero that soaks attention from the enemy team and takes the role of an initiator and disabler. As such, Doom is an ideal target for 
Reaper's Scythe, as it is likely Doom will be at the fore-front of any fight.
Doom
* Doom generally does not impede Sven in almost any way, provided he has activated God's Strength beforehand.
Doom
* The slow applied from 
Corrosive Skin offsets the movement speed bonus granted by Scorched Earth and the tick-based damage from Infernal Blade and Doom will continually slow Doom down. This allows Viper, much like Sniper, to 'kite' Doom and keep him at a safe distance between the two. Additionally, Corrosive Skin applies an attack-speed slow which is fairly crippling to a hero such as Doom that, naturally, has a high base attack-time, poor agility gain and builds little attack-speed items.
* Since Doom does not disable auto-cast abilities, Viper's 
Poison Attack will continue to work. Doom may find it hard to close the distance between himself and Viper, and thusly difficult to effectively lockdown and continually deal damage through his abilities.
Ember Spirit
* Batrider has huge damage from his 
Sticky Napalm and hand strikes on the target, with this effect. And Ember Spirit not only has a small reserve of health, but also has a melee type of attack. If these two collide on the center line, then Ember Spirit will have to finish off several creeps from afar with a Sleight of Fist, otherwise he will lose a lot of health from long-range Batrider attacks under Sticky Napalm, and possibly even kill, because Ember Spirit does not have the ability to interrupt Batraider with his damage if he decides to attack
* Ember Spirit is a very tasty target for 
Flaming Lasso, because it has a small reserve of health, and all the power lies in the abilities that Flaming Lasso forbids using, this can help the Batraider team quickly deal with the unpleasant "jumping" Ember Spirit in a fight if he gets into Flaming Lasso

Doom
* Heroes who often build Linken's Sphere: 
Weaver, 
Morphling, 
Medusa.
Doom
* Heroes with a slow attack rate will find themselves struggling to take out Tombstone, like Doom.
Doom
* Heroes who often build Linken's Sphere: Weaver, Morphling, Medusa.
Ember Spirit
* 
Queen of Pain can be a good hero for dealing with Ember Spirit with 
Orchid Malevolence, her pure damage nuke in 
Sonic Wave and a slow in 
Shadow Strike. However, Queen of Pain can be punished by Ember Spirit, as his Searing Chains prevents her from getting 
Blink off.
Doom
* Heroes who can disable Mars but cannot do any damage to him, meaning he just tanks their abilities: Doom, 
Magnus.
Ember Spirit
* Heroes who rely on high mobility are especially vulnerable to Primal Roar: 
Storm Spirit, 
Ember Spirit, Queen of Pain.
Ember Spirit
* Oracle can shut down both of Ember's early game abilities. Fortune's End can dispel 
Flame Guard on Ember Spirit and 
Searing Chains on allies.
* When Ember Spirit is affected by Fortune's End, his Fire Remnants move at 0 movement speed.
* Disarming him with Fate's Edict does affect Ember's Sleight of Fist ability, possibly making him useless for a few seconds in the late game without a dispel or spell immunity. This is especially good if he has a rapier or two. However, positioning for this is difficult when Ember plays far back.
Doom
* Heroes with the ability to heal allies will not be able to heal heroes affected by Doom: 
Chen, 
Dazzle, 
Io, 
Oracle, 
Omniknight, 
Witch Doctor, 
Winter Wyvern, 
Abaddon, etc.
Ember Spirit
* Huskar can destroy Ember Spirit both on the line and in the game. It will be extremely difficult for Ember Spirit to finish off the creeps, because Huskar will not let him approach them, and if Ember Spirit does come up, Huskar just shuts him up with his 
Burning Spear and Ember Spirit will have to go to the base or bring himself treatment, or continue to stand and die. In all cases, Ember Spirit will go into negative
Additional:
* Ember Spirit does minimal damage to Huskar until the very late game.
* Huskar can destroy Ember Spirit both on the line and in the game. It will be extremely difficult for Ember Spirit to finish off the creeps, because Huskar will not let him approach them, and if Ember Spirit does come up, Huskar just shuts him up with his Burning Spear and Ember Spirit will have to go to the base or bring himself treatment, or continue to stand and die. In all cases, Ember Spirit will go into negative
Doom
* Doom with the {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent} talent can be useful against heroes with troublesome passive skills while also disabling them for a long time: Phantom Assassin, 
Enchantress, 
Huskar, 
Underlord.
Ember Spirit
* Impetus will deal huge amounts of damage when he uses a Fire Remnant to escape.
* Flame Guard is useless against Impetus as it deals Pure damage.
* Enchant can be used to dispel Flame Guard.
Doom
* Doom with the {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent} talent can be useful against heroes with troublesome passive skills while also disabling them for a long time: Phantom Assassin, Enchantress, Huskar, Underlord.
Additional:
* Devour can easily eat creeps controlled by Enchant, limiting her ganking potential.
* Doom reduces the amount of healing received by Enchantress and her allies from Nature's Attendants. In addition, when Doom chooses the Doom applies Break talent, it can also disable Untouchable.
Doom
* 
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 team fight - both for mobility, damage and crowd control. Timbersaw offers very little, impactful right-click damage, and thus Doom is particularly crippling against him.
* Additionally, when Doom chooses the {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent} talent, Doom disables 
Reactive Armor, which effectively removes the durability which Timbersaw is commonly known for.
Additional:
* Doom shuts down Timbersaw completely, negating his mobility and preventing him from doing any damage. It also breaks Reactive Armor's passive bonuses from 
Aghanim's Scepter.
* Infernal Blade can stun Timbersaw several times in a fight, potentially interrupting Timber Chain. Also it's useful since Timbersaw has high HP due to the damage scales based on max HP.
Ember Spirit
* Searing Chains prevents usage of Timber Chain.
* Timbersaw is vulnerable to magical burst damage, which Ember Spirit provides with Fire Remnant and Flame Guard.
* Timbersaw's abilities deal pure damage, thus they cannot remove Flame Guard.
Doom
* Doom completely takes Windranger out of a team fight, a hero who relies heavily on using abilities and items to contribute in team fights.
Additional:
* Doom completely takes Windranger out of a team fight, a hero who relies heavily on using abilities and items to contribute in team fights.
Ember Spirit
* The high mobility provided by Fire Remnant makes it hard for Windranger to find a good position to land Shackleshot or a full duration of Focus Fire.
* Flame Guard and Searing Chains deal considerable magical damage to Windranger which she cannot avoid with Windrun.
* Searing chains also negates the mobility from Windrun.
Doom
* Doom can eats Nature's Prophet's treants with Devour and gains lots of gold.
* Doom can buy 
Radiance or use his 
Scorched Earth to quickly wipe out a swarm of Treants.
* Doom and a ministun from Infernal Blade's prevents Nature's Prophet from escaping with Sprout and Teleportation.
Ember Spirit
* Ember Spirit can easily deal with 
Nature's Call by using his Flame Guard and with 
Battle Fury. He also has multiple ways of escaping 
Sprout. Additionally, Ember Spirit can break Sprout's trees with Activate Fire Remnant and interrupt 
Teleportation with Searing Chains.
Additional:
* Sleight of Fist with Battle Fury deals a lot of damage to Nature's Prophet's team if they stand close to his Treants, as well as killing all the Treants with ease.
* Ember Spirit with Fire Remnant and 
Boots of Travel can be very active around the map, which enables him to quickly teleport and defend the objective Nature's Prophet is attacking whenever he tries to push.
Doom
* 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.
Ember Spirit
* Crystal Maiden is extremely fragile and she's an easy target for him. She has no real disables that can lock Ember Spirit down, and all of her skill damage can be negated with Flame Guard. The damage from Searing Chains, Flame Guard, and Sleigh of Fist can easily take her down.
Doom
* 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.
Ember Spirit
* Ember Spirit has much higher mobility in Fire Remnant than Void Spirit.
* Ember's Flame Guard is effective against Void Spirit's spells, as most of them deal magical damage.
* The root from Searing Chains prevents Void Spirit from using Dissimilate or Astral Step.
Doom
* Doom can easily kill Chen's creeps and obtain their abilities with Devour.
* Scorched Earth's area-of-effect can clear multiple of Chen's creeps at once.
* Doom renders Chen completely helpless, and unable to save himself or his allies with 
Hand of God. Aghanim's Scepter upgraded Doom also allows Doom to cast Doom on himself and disable both, Chen and his creeps around him.
Ember Spirit
* 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.
Doom
* Infernal Blade deals high damage to Pudge due to his scaling health and strength gain from 
Flesh Heap.
* Using Doom with timing against Pudge who had just activated 
Rot would usually kill him.
Additional:
* 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.
Ember Spirit
* Heroes with a high degree of mobility and invisibility are hard to catch with Meat Hook: Ember Spirit, Riki, Clinkz, Queen of Pain.
Doom
* Supports with useful teamfight or contribution spells will be helpless against Doom: Dazzle, Oracle, 
Warlock.
Additional:
* Doom will not only prevent Warlock from casting his abilities in team fights, but also it reduces the healing from Shadow Word.
* Devour allows Doom to acquire a stun from neutral creeps, allowing him to interrupt Upheaval without having to use Doom.
Ember Spirit
* A pre-placed Fire Remnant allows Ember Spirit to escape Upheaval.
* Flame Guard blocks Shadow Word's damage.
* Sleight of Fist allows Ember Spirit to attack from outside of Upheaval's range, and Searing Chains lets him interrupt it.
Doom
* Both Infernal Blade and Doom can be used to disable Bane while he is channeling Fiend's Grip.
* A similar effect can be achieved by using Devour on {U:Centaur Conqueror}, which will give him access to 
War Stomp.
Ember Spirit
* Heroes who commonly buy Linken's Sphere: 
Luna, Weaver, Morphling, Queen of Pain, Ember Spirit.
Doom
* Weak damage but high tick rate or persist in a long time: Slark, 
Gyrocopter, Queen of Pain, 
Shadow Shaman (
Shackles), 
Jakiro, 
Pugna, Doom
* Heroes that can quickly deal damage to her, regardless of how weak they are, can easily break through her Refraction:
* Multiple attackers thanks to summoned units or clones: Meepo, Witch Doctor, 
Lycan, 
Enigma, Shadow Shaman
* Multiple attackers thanks to illusions: 
Phantom Lancer, 
Chaos Knight, 
Naga Siren (bonus for her 
Ensnare). Also despite the visual effects, Templar Assassin does not spill damage against illusions or buildings, so she is not a really good hero to clean up illusions.
* Weak damage but high tick rate or persist in a long time: Slark, Gyrocopter, Queen of Pain, Shadow Shaman (Shackles), Jakiro, Pugna, Doom
Ember Spirit
* Searing Chains and Flame Guard quickly burn through 
Refraction instances exposing her low health pool.
* Templar Assassin has no inherent way to prevent Ember Spirit from escaping, a good Ember player also will be able to dodge her meld attack
* Ember Spirit`s Searing chains give true sight into invisibility, why Templar Assassin can't hide from it in 
Meld and get out of the fight using Blink Dagger
Additional:
* Flame Guard burns quickly through Refraction charges, which is why it can interrupt Templar Assassin, giving his team the opportunity to kill her.
* Ember Spirit can dodge a blow from Meld with Sleight of fist, providing him an advantage in a 1v1 situation.
* Searing Chains give true sight into invisibility, why Templar Assassin can't hide from it in Meld and get out of the fight using Blink Dagger.
Doom
* Heroes with the ability to heal allies will not be able to heal heroes affected by Doom: Chen, Dazzle, Io, Oracle, Omniknight, Witch Doctor, Winter Wyvern, Abaddon, etc.
Ember Spirit
* Heroes with either magical, physical or pure damage burst: 
Bane, Ember Spirit, 
Leshrac, 
Lina, Luna, 
Nyx Assassin, Phantom Assassin, 
Skywrath Mage, 
Tinker, 
Ursa, Void Spirit.
Ember Spirit
* Ember Spirit absorbs quite a large amount of magical damage with its Flame Guard, and in addition dodges the abilities of 
Dragon Slave and 
Light Strike Array with its Sleight of Fist
Additional:
* Ember Spirit absorbs quite a large amount of magical damage with its Flame Guard, and in addition dodges the abilities of Dragon Slave and Light Strike Array with its Sleight of Fist.
Ember Spirit
* Disruption is not reliable enough to catch an Ember Spirit with a backup Fire Remnant.
* Sleight of Fist will also make quick work of the spawned illusions.
* The best you can do against an Ember Spirit is to dispel his Flame Guard with your Demonic Purge.
Ember Spirit
* 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.
Doom
* Doom prevents Storm Spirit from using all of his abilities and items, rendering Storm Spirit useless in a fight.
Ember Spirit
* Flame Guard absorbs up to 500 magical damage (700 with Level 10 talents), which helps Ember Spirit survive against Storm Spirit's high magical damage.
* Searing Chains can root enemies up to 3 seconds, making Storm Spirit unable to escape with Ball Lightning.
* Fire Remnant deals high magical damage when casting multiple instances at once, granting Ember Spirit the damage to burst Storm Spirit down in the early to mid game.
Doom
* Doom can stop Death Prophet from casting spells, which makes her useless during team fights if she didn't cast Exorcism before the fight, and also nullifies healing from Exorcism and Spirit Syphon. Furthermore, Doom can use Scorched Earth to chase after her.
Ember Spirit
* Flame Guard blocks Dark Willow's magical burst damage, and harms her if she tries to get close to attack with Bedlam.
* Sleight of Fist and Fire Remnant makes it hard for Dark Willow to fully disable Ember Spirit.
Doom
* Arc Warden relies on items and abilities, as well as his 
Tempest Double, to deal damage to enemies. Doom effectively denies that and makes Arc Warden useless in fights.
Doom
* Doom makes Ogre Magi less disruptive.
* Infernal Blade effectively negates Ogre Magi's durability.
* With Aghanim's Scepter, he can disable Multicast.
Ember Spirit
* Zeus laneing against Ember is going to be punished with Sleight of Fist due to his low health pool
* Zeus's chip damage from 
Arc Lightning and other spells is nullified from Ember's Flame Guard.
Additional:
* Ember Spirit has a built-in antimagic shield, and Zeus has nothing but this magical damage, because of this, their confrontation on the center line can turn out to be sad for Zeus. If on such a line Ember Spirit will finish off all creeps under its Flame Guard, and Zeus with the help of Arc Lightning, then eventually Zeus will lose mana faster, and will be forced to look for ways to replenish it
* Ember Spirit can interrupt Zeus with his "jumping" abilities, the fact is that Zeus deals damage from his abilities directly, while Ember Spirit disappears for milliseconds from the battlefield when flying during the Sleight of Fist action or when flying into Fire Remnant
Doom
* 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 his upgraded level 25 talent, 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.
* Doom prevents Bristleback from casting his two low cooldown abilities, which then prevents him from utilizing 
Warpath.
* If Doom chooses the Level 25 talent {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent}, he can disable 
Bristleback and Warpath, taking away much of his durability and damage potential in team fights.
Ember Spirit
* Searing Chains can stop Charge of Darkness if timed correctly.
* 
Activate Fire Remnant can be used to escape an approaching Spirit Breaker, or lead Spirit Breaker into a bad situation.
* Fire Remnant and Sleight of Fist allows Ember Spirit to dodge Charge of Darkness if timed correctly.
Ember Spirit
* Fire Remnant allows Ember Spirit to escape while Ruptured.
Additional:
* Fire Remnant allows Ember Spirit to escape Bloodseeker while 
Ruptured.
Doom
* Doom's low armor makes him weak against Alchemist's high physical damage output.
Doom
* Doom can disable 
Chemical Rage's increased healing, rendering Alchemist helpless against Doom.
* Attacks from Infernal Blade can deal serious damage to Alchemist as it deals damage based on the hero's maximum health.
Ember Spirit
* Ember's magic damage build is able to burst down Alchemist due to his low strength gain and Alchemist's normal item pick up.
Doom
* Infernal Blade's damage is calculated by percentage of maximum health. Since Spectre is usually tanky, it will hurt her more than most normal attacks.
* Doom can take out Spectre out of a teamfight completely. When combined with the level 25 talent {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent}, it will disable both 
Desolate and 
Dispersion, taking away her extra damage and durability.
Additional:
* 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 disable Spectre passive skills, reducing her potential in teamfights.
Doom
* Infernal Blade's damage is calculated by a percentage of maximum health, meaning that it will hurt Axe more than most normal attacks, negating some of his durability.
* 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, and his high base health allows him to take a few Helixes with no danger.
* Doom makes Axe less disruptive, preventing him from using his skills or items. At level 25, there is a branch of the talent tree that makes Doom apply Break, allowing Doom to disable Counter Helix, making Axe effectively useless for a lengthy duration.
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 due to Doom, Axe offers very little in the way of damage, effectively removing him from a fight.
Doom
* Doom can completely shut down Dazzle through Doom, as it prevents him from casting his abilities and, by extension, gaining Bad Juju stacks.
Doom
* 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 cancelling a 
Black Hole.
* While Doom can be blocked by a Linken's Sphere, which is a common item on Enigma, Aghanim's Scepter upgraded Doom allows Doom to cast Doom on himself to affect enemies near him, and if Doom can combine this with Blink Dagger, he will be able to jump on Enigma while he is channeling Black Hole. Aghanim's Scepter upgraded Doom can also cancel Black Hole if any of Enigma's allies affected by Doom gets too close to him for it's duration, ignoring both, 
Black King Bar and Linken's Sphere.
Ember Spirit
* Ember Spirit easily finishes off all creeps on the line against Earth Sprit, exchanging health with him under his Flame Guard, which is why Earth Spirit can leave the line for ganks very early and without the necessary amount of gold and levels, which will give the Ember Spirit team an advantage to fight off such ganks
* The Sleight of Fist ability helps Ember Spirit dodge all of Earth Spirit's abilities, which makes his gank potential practically useless against Ember Spirit, and with the purchase of Black King Bar, Ember Spirit can use Sleight of Fist to combine with Searing Chains to catch and kill Earth Spirit.
Additional:
* Ember Spirit easily finishes off all creeps on the line against Earth Sprit, exchanging health with him under his Flame Guard, which is why Earth Spirit can leave the line for ganks very early and without the necessary amount of gold and levels, which will give the Ember Spirit team an advantage to fight off such ganks
* The Sleight of Fist ability helps Ember Spirit dodge all of Earth Spirit's abilities, which makes his gank potential practically useless against Ember Spirit, and with the purchase of Black King Bar, Ember Spirit can use Sleight of Fist to combine with Searing Chains to catch and kill Earth Spirit.
Doom
* Doom will make Abaddon unable to use Mist Coil, Aphotic Shield, and the active component of Borrowed Time, also upgraded with Aghanim's Scepter can break Curse of Avernus and the passive component of Borrowed Time ,which means his allies could be easily disabled or killed.
Doom
* Doom completely takes Mirana out of a team fight, a hero who relies heavily on using abilities and items to contribute in team fights.
Doom
* Infernal Blade deals scaling damage and is useful against high HP targets such as Tidehunter.
* Doom prevents Tidehunter from casting his 
Gush, 
Anchor Smash and 
Ravage, making him useless in team fights.
* If Doom chooses the Level 25 talent {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent}, he can also disable 
Kraken Shell, reducing his survivability.
Ember Spirit
* Sleight of Fist keeps Ember Spirit invulnerable until he hits every unit in its area of effect allowing him to stall for large amounts of time against Broodmother and her large amounts of spiderlings, or potentially damaging them enough if equipped with an item to improve wave clearing such as Battle Fury or 
Maelstrom to prevent her pushes entirely.
* Flame Guard will damage any of Broodmother's spiders in an area, deterring her from attempting to kill him. It can also be used during Sleight of Fist to amplify damage done.
* Fire Remnant allows Ember Spirit an escape from Broodmother that is unaffected by her Incapacitating Bite.
Ember Spirit
* Flame Guard makes Dark Seer not deal any damage with his skills to Ember Spirit.
Doom
* Tinker is heavily dependent on his abilities and Doom prevents him from using any of them.
* This becomes even worse if Doom chooses the level 25 talent {ValueColor:1|Doom applies Mute|25tal} {Symbol:Talent}, which will prevent Tinker from using items such as Blink Dagger.
Additional:
* 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.
Ember Spirit
* Ember Spirit's Fire Remnant is an easy way to escape from Clockwerk's Power Cogs.
* Flame Guard blocks most of the magical damage Clockwerk does.
Doom
* Infernal Blade deals scaling damage and is useful against high HP targets such as Elder Titan. It also can interrupt 
Echo Stomp if quick enough.
* Doom has very low base armor and naturally high HP, so he isn't significantly affected by 
Natural Order.
Doom
* 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.
Ember Spirit
* Heroes with high mobility can be prevented from using it to their advantage with Earthbind, even if they pack a dangerous arsenal: Earth Spirit, Ember Spirit, Storm Spirit, 
Nature's Prophet, Phantom Assassin, Riki, 
Anti-Mage, Weaver.
* See items and abilities disabled by roots
Doom
* Besides Lone Druid and Meepo, Doom is potentially good versus every hero since Doom will render any hero helpless for up to 16 seconds. This is particularly true for fragile heroes that heavily rely on mobility to stay alive.
Ember Spirit
* Meepo is quite fragile in the early game and can be easily taken down by Flame Guard's and Searing Chains' damage. Later on, Meepo is very vulnerable to Sleight of Fist's damage due to Battle Fury's cleave on multiple Meepos.
Additional:
* Sleight of Fist combined with Battle Fury, Maelstrom and 
Daedalus will allow Ember Spirit to make a quick work of Meepo if his clones are crowded around each other.
* Searing Chains interrupts Meepo's initiating because Meepo's clones do not have spell immunity.
Doom
* Doom with the {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent} talent can be useful against heroes with troublesome passive skills while also disabling them for a long time: Phantom Assassin, Enchantress, Huskar, Underlord.
Ember Spirit
* Heroes that heavily depend on illusions or summons, (Naga Siren, 
Terrorblade, Phantom Lancer, Lycan,...) are vulnerable to Sleight of Fist and even more so if Ember Spirit has Battle Fury.
Ember Spirit
* 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.
Ember Spirit
* 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.
Doom
* Heroes that can keep Luna locked down for a long time can be a threat (she is very item and spell dependent): Faceless Void, 
Legion Commander, Doom.
Doom
* Phantom Lancer's illusions can make it difficult to Doom the real hero. Should Doom figure out the real hero, the illusions can make it difficult to cast any abilities, as their hitboxes can be used to body-block the real Phantom Lancer.
* Phantom Lancer is an ideal 
Diffusal Blade carrier. With it, he can quite easily deplete Doom's already poor mana pool, potentially making him unable to cast his abilities to escape, retaliate or heal.
* Doom lacks any effective ability to clear waves of creeps and illusions, as the vast majority of his abilities are single-target. Without an answer, Doom may find it difficult to deal with Phantom Lancer's presence.
Doom
* Doom's Doom marks Phantom Lancer with a highly visible effect, and also silences and mutes him.
* Heroes with undispellable debuffs will help identify the real Phantom Lancer through visual effects or debuff indicators, provided that it was cast on the real Phantom Lancer to begin with:
* Doom's Doom marks Phantom Lancer with a highly visible effect, and also silences and mutes him.
* 
Bloodseeker's Rupture shows a clear red trail effect on the real Phantom Lancer.
* 
Ancient Apparition's 
Ice Blast will only debuff Phantom Lancer and not his illusions.
* 
Grimstroke's 
Soulbind is undispellable.
* 
Shadow Demon's 
Demonic Purge is undispellable.
* 
Monkey King's 
Jingu Mastery is undispellable and puts a big yellow Mark over his head.
Ember Spirit
* Sleight of Fist is the natural counter to Phantom Lancer's army of illusions, especially when combined with Battle Fury.
Additional:
* Sleight of Fist, allows Ember Spirit to destroy all of Phantom Lancer's illusions.
* Flame Guard also deals significant damage to illusions, and protects against Spirit Lance.
* Phantom Rush is unable to catch Ember Spirit when he teleports to his Fire Remnants.
Ember Spirit
* Heroes with high physical and magical damage alike are a huge hazard for Muerta, as they can deal serious damage to her even if she has 
Pierce the Veil active: Luna, Lina, Tusk, 
Broodmother, 
Shadow Fiend, Ember Spirit, Gyrocopter, 
Vengeful Spirit, 
Arc Warden, Medusa, Shadow Shaman.
Ember Spirit
* Any hero with teleport abilities (e.g. Ember Spirit, Storm Spirit) can easily break Static Link.
Ember Spirit
* Certain Hero's potential lies on the combo of their abilities. As an example, Ember Spirit can cast Sleight of Fist and Searing Chains together to root and damage enemies from a far distance. Yet for 
Rubick, casting Searing Chains can only catch enemies at a close distance, and Sleight of Fist does little more than a scratch of right click.
* It is arguably possible to group spells together after getting Aghanim's Scepter, but stealing two separate spells from one single enemy is somewhat luxurious in an intense fight.
Doom
* Heroes without blink mechanisms or spell immunity will have a hard time positioning against 
Pit of Malice: 
Sven, 
Tiny, 
Wraith King, 
Dragon Knight, Meepo, Doom, 
Bounty Hunter, 
Dark Seer, 
Undying, 
Alchemist, Legion Commander.
Doom
* Doom with the {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent} talent can be useful against heroes with troublesome passive skills while also disabling them for a long time: 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 to prevent him from using Fiend's Gate to escape.
Ember Spirit
* Heroes with strong area-of-effect damaging and/or disabling abilities will be able to intercept Underlord and his team when they exit from Fiend's Gate: Luna's Aghanim's Scepter upgraded

Doom
* Heroes with silences: Puck, Doom, Riki.
Ember Spirit
* Heroes with good mobility to avoid Jakiro's abilities and with good chase to punish Jakiro from pushing a tower: Bloodseeker, Ember Spirit, 
Juggernaut, Phantom Assassin, Weaver.
Ember Spirit
* Heroes with high mobility will be able to avoid Gyrocopter's area attacks: Storm Spirit, Morphling, Ember Spirit
Doom
* Heroes with silencing abilities can be particularly deadly when Slark is trying to escape: 
Silencer, Death Prophet, Puck, Doom.
Doom
* Heroes with the ability to heal allies will not be able to heal heroes affected by Doom: Chen, Dazzle, Io, Oracle, Omniknight, Witch Doctor, Winter Wyvern, Abaddon, etc.
Ember Spirit
* With 
Vendetta, Nyx Assassin can move closely to Ember Spirit when he's farming with his Flame Guard and use 
Spiked Carapace with 
Impale to provide a reliable and long disable.
Additional:
* Spiked Carapace can be easily triggered by Flame Guard or Battle Fury, setting up a deadly Impale.
Doom
* A well-timed Doom prevents Nyx Assassin escaping with Vendetta and fighting back with Spiked Carapace.
* Doom's high health also allows him to easily shrug off Nyx Assassin's burst damage and fend him off.
Ember Spirit
* Heroes who rely on damage over time as Spiked Carapace can block and reflect only one instance of damage: Jakiro, 
Viper, Venomancer, Huskar, Ember Spirit, Dark Seer, Sand King, Doom, Dawnbreaker. However, this also means they are easily stunned.
Ember Spirit
* Heroes that heavily depend on illusions or summons, (Naga Siren, Terrorblade, Phantom Lancer, Lycan,...) are vulnerable to Sleight of Fist and even more so if Ember Spirit has Battle Fury.
Doom
* Silencer's 
Global Silence and Doom's Doom makes Earthshaker temporarily useless.
Ember Spirit
* Ember Spirit with Sleight of Fist and Activate Fire Remnant
* 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
Ember Spirit
* Heroes with escaping and disjointing abilities can be good against Juggernaut:Anti-Mage Riki, Queen of Pain, Puck, Storm Spirit, Ember Spirit, Slark etc.
Doom
* Heroes with the ability to heal allies will not be able to heal heroes affected by Doom: Chen, Dazzle, Io, Oracle, Omniknight, Witch Doctor, Winter Wyvern, Abaddon, etc.
Doom
* Terrorblade can use 
Sunder to save his allies who are Doomed.
Ember Spirit
* Ember Spirit can deal devastating damage to illusion heroes like Terrorblade with Sleight of Fist. Terrorblade also has no way of preventing Ember Spirit from getting Activate Fire Remnant off. Additionally, Ember Spirit's ability to fight from long range as well as his wide skill set won't give many opportunities for Terrorblade to get Sunder off.
Additional:
* Ember Spirit can deal devastating damage to Terrorblade and his illusions with Sleight of Fist, Flame Guard and Fire Remnant.
* Terrorblade has no disable to lock down Ember Spirit and prevent him from escaping with Fire Remnant. In addition, he doesn't like purchasing disabling items like 
Scythe of Vyse or 
Abyssal Blade, which are the only solutions to deal with Ember Spirit.
Ember Spirit
* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, Storm Spirit, Ember Spirit, Lycan, Bloodseeker, Anti-Mage, 
Timbersaw.
Doom
* Doom is generally tanky and has naturally high health, allowing him to survive Puck's onslaught in any stage of the game.
* His namesake ultimate Doom is one of the best solutions to counter Puck, as it will silence Puck for a lengthy duration. A Puck silenced for more than 3 seconds usually ends up dead.
* In addition, if Doom chooses the Level 25 talent Doom applies Mute, Puck will not be able to use items altogether, most especially Blink Dagger and Eul's Scepter of Divinity, making Doom a nightmare to deal with as Puck.
Doom
* High health heroes (Axe, Doom) fall fast with Fury Swipes stacks.
Doom
* Doom makes Ursa less disruptive, and it cannot be dispelled with Enrage upgraded with Aghanim's Scepter.
Ember Spirit
* Anti-mage is potentially good against Ember Spirit since he can burn Ember Spirit's mana, prevent him from escaping or using his skill. Anti-Mage has high magic resistance, which will reduce most of the damage from Ember Spirit's skill set. However, Anti-Mage lacks any form of stuns or lockdowns, and may struggle to kill Ember Spirit if he still has some mana left.
Doom
* Doom shuts down Anti-Mage's escape capabilities with Blink. The ability also deals pure damage, which ignores the protection from Counterspell.
* However, a well-timed Counterspell can reflect it back.
* If Doom has Aghanim's Scepter, Doom can break 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.
* However, Doom must be careful when using Doom as a well-timed Counterspell can block and reflect it back against Doom himself.
* The Level 25 talent {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent} will also disable 
Mana Break and Counterspell's passive component, which makes Anti-Mage significantly less effective in fights and more susceptible to the high magical damage of Doom's abilities and his allies.
Doom
* Single-target disablers will have difficulty locking down a Chaos Knight with Phantasm active: Bane, 
Beastmaster, Bloodseeker, 
Clockwerk, Doom, Shadow Shaman.
Ember Spirit
* Heroes with strong area damage to destroy Phantasm illusions: Axe, Ember Spirit, Legion Commander, Phoenix
Additional:
* Ember Spirit is evasive and can dodge close encounters with melee heroes like Chaos Knight. Ember Spirit can't be caught with the slow from 
Reality Rift, and Flame Guard and Sleight of Fist can bring Phantasm's illusions down quickly.
Ember Spirit
* 
Shadowraze can easily remove the protection from Flame Guard and kill Ember Spirit due to his low health.
* Ember Spirit is very vulnerable to physical damage from 
Necromastery.
Doom
* 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
* Due to the nature of the hero, Sniper is typically situated in the back of the fight, potentially making him a difficult target to initiate on and fight.
* Sniper is largely a right-click hero, and as such isn't as an effective of a Doom target as other heroes.
* Thanks to 
Shrapnel and 
Headshot, Sniper is able to effectively 'kite' Doom, preventing him from closing the distance between the two.
Ember Spirit
* Ember Spirit can close the distance between Sniper easily with his Activate Fire Remnant and further keep Sniper in place with Searing Chains.
* With the help of Aghanim's Scepter, Sniper cannot outrun Ember Spirit or chase him, even if Sniper builds mobility items.
Ember Spirit
* Faceless Void is one of the best heroes against Ember Spirit, providing a lot of ways of dealing with him. Ember Spirit becomes a lot weaker if affected by 
Time Dilation, as he can no longer spam Sleight of Fist.
* 
Chronosphere is also a reliable lockdown for Ember Spirit, although it can be evaded sometimes by Activate Fire Remnant. Additionally, Void can easily negate Sleight of Fist damage with 
Time Walk.
* And finally, Void is a great Diffusal Blade carrier. Not only 
Manabreak's physical damage not negated by Flame Guard, but it also burns Ember Spirit's mana. That, in turn, prevents him from escaping if he survived Chronosphere.
Doom
* 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.
Ember Spirit
* Ember Spirit's Flame Guard provides no protection against Clinkz's physical damage output.
* Ember Spirit's low armor and health make him easy to kill quickly if a teammate can hold him down.
* If Clinkz has farmed an item that can disable, he can sneak up to and hunt down Ember Spirit while he farms or split pushes alone.
Doom
* 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.
Ember Spirit
* The pure damage provided by 
Purification is a great addition for killing Ember Spirit, as well as a good way of saving teammates.
* 
Guardian Angel will temporarily save his allies from Sleight of Fist's physical damage, and Ember Spirit is not a hero that will get Orchid Malevolence to counter it.
Doom
* Doom applies a basic dispel upon cast, so it can remove Guardian Angel.
* Casting Doom on Omniknight will also prevent him from healing allies with Purification, or casting buffs like 
Repel and Guardian Angel, basically turning him into a harmless creep.
Additional:
* Doom turns Omniknight into a walking creep, or completely takes out his buffed cores, also removing Heavenly Grace and Guardian Angel in the process.
* With Devour used on Satyr Banisher, Doom will have access to Satyr Banisher's 
Purge, which will allow him to remove Heavenly Grace and Guardian Angel.
Ember Spirit
* Ember Spirit has a small mana pool, which is why QW-Invoker can burn it out very effectively with his own 
E.M.P., do not give Ember Spirit the opportunity to play with his abilities and cause damage with them in a fight.
* QW-Invoker Destroys Ember Spirit's Flame Guard with his own 
Tornado, which is why Ember Spirit cannot defend against Invoker's strong magic damage.
Additional:
* Ember Spirit has a small mana pool, which is why QW-Invoker can burn it out very effectively with his own E.M.P., do not give Ember Spirit the opportunity to play with his abilities and cause damage with them in a fight.
* QW-Invoker Destroys Ember Spirit's Flame Guard with his own Tornado, which is why Ember Spirit cannot defend against Invoker's strong magic damage.
Doom
* Doom completely takes Invoker out of a team fight, a hero who relies heavily on using abilities and items to contribute in team fights.
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.
Doom
* Heroes with low mana pools (eg.
Doom and
Tidehunter) will feel the effects of Silencer's Intelligence Steal far more than others.
Ember Spirit
*
Global Silence and 
Last Word can prevent Ember Spirit from casting Activate Fire Remnant to escape.
Glaives of Wisdom also provide high pure damage that is not negated by Flame Guard.
Arcane Curse is also a potent harassing tool in the laneing stage as its cooldown is lower than Flame Guard's.
