Necrophos
* Outworld Destroyer is not exceptionally dangerous to Necrohpos because of his Ghost Shroud, but his 
Astral Imprisonment can save his allies from Necrophos's Reaper's Scythe, though only if he uses it at the right time, If an Outworld Destroyer is nearby, Necrophos should not use Reaper's Scythe unless he has banished himself, or has banished two heroes within 15 seconds
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.
Necrophos
* 
Arcane Curse punishes Necrophos if tries to spam Death Pulse, increasing the duration of the slow and damage taken over time.
* 
Last Word heavily damages Necrophos and also silence him for a lenghty duration.
* 
Glaives of Wisdom will reduce temporarily Necrophos intelligence on each hit dealing hindering his ability to spam Death Pulse, also reducing his attack damage and mana pool; dealing increasing amounts of phisical and pure damage each time. Silencer will permanently steal Necrophos intelligence if Necrophos is killed by him or if he dies nears him.
* 
Global Silence turns Necrophos almost useless for a long time, allowing Silencer and his team to easily dispatch him, since Necrohpos heavily relies on his spells to survive.
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.
Necrophos
* Time Dilation while 
Death Pulse and 
Reaper's Scythe are on cooldown will make these abilities unusable for a long time, rendering Necrophos nearly useless.
* Necrophos cannot use 
Ghost Shroud while he is inside Chronosphere which makes it easy to kill him.
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.
Necrophos
* Tornado allows Invoker to purge Necrophos's Ghost Shroud, nullifying any benefits he could get out of it
* E.M.P. allows Invoker to burn Necrophos's mana, preventing him from using his abilities constantly
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.
Necrophos
* Heroes who possess abilities that can save targets from being killed by Reaper's Scythe: 
Abaddon, 
Bane, 
Outworld Destroyer, 
Shadow Demon, 
Omniknight, etc.
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.
Necrophos
* 
Mana Drain depletes Nercophos's mana pool, preventing him from using his abilities.
* 
Finger of Death deals high magical damage, which becomes amplified by Ghost Shroud.
Ember Spirit
* High priority targets like 
Queen of Pain, 
Drow Ranger, 
Ember Spirit can't get caught out from 
Lion's long range disables, making it harder to them fulfill their roles, and making it easy to target them.
Additional:
* 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.
Necrophos
* The huge physical damage taken from 
Vendetta will force Necrophos to use Ghost Shroud, which is good for a followup with 
Dagon and 
Ethereal Blade, both of which are common items on Nyx Assassin.
* Using Ghost Shroud also sets Necrophos up for a 
Mind Flare or 
Impale.
Ember Spirit
* Spiked Carapace can be easily triggered by Flame Guard or 
Battle Fury, setting up a deadly Impale.
Additional:
* 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.
Ember Spirit
* Heroes who rely on damage over time as Spiked Carapace can block and reflect only one instance of damage: 
Venomancer, 
Huskar, Ember Spirit, 
Dark Seer, 
Sand King, 
Doom, 
Dawnbreaker. However, this also means they are easily stunned.
Necrophos
* Anti-Mage can withstand magical burst damage much better than other carries, making him effective against nukers: 
Lich, 
Necrophos, 
Oracle, and 
Leshrac.
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.
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
* 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.
Necrophos
* 
Nether Ward causes Death Pulse to actually damage Necrophos rather than heal him. Meanwhile, Reaper Scythe's gigantic mana cost while Necrophos is near the Nether Ward can often instantly kill him.
* 
Nether Blast and 
Life Drain both make quick work of Necrophos's small healthpool, especially during Ghost Shroud. The latter also makes him an unappealing target for Reaper's Scythe, and can often force Necrophos to use it defensively as he has no other means of interrupting his channeling.
Necrophos
* 
Ice Blast completely nullifies any healing, making Necrophos unable to stay in a teamfight to sustain his teammates (and himself) or deal gradual damage to the enemy, else he be faced with a quick death if focused on.
Necrophos
* Ghost Shroud amplifies damage taken from all of Grimstroke's abilities. Necrophos is particularly vulnerable to Ink Swell and Phantom's Embrace while in Ghost Shroud.
* Death Pulse works against Necrophos in lane by keeping his creeps alive and add damage to Stroke of Fate.
Necrophos
* Dazzle's 
Shadow Wave is a spammable healing ability that spreads around his entire team, slowing the death of his teammates as effectively as Necrophos spreads damage to them.
* If not immediately, 
Shallow Grave delays his ally from gradually dying to Necrophos's abilities, especially Reaper's Scythe.
* However, bear in mind that Dazzle's 
Poison Touch, Shadow Wave and 
Bad Juju all deal physical damage, and Dazzle has no abilities to help him deal magical damage at all, which can cause problems for Dazzle to kill Necrophos if he uses Ghost Shroud to protect himself.
Additional:
* Reaper's Scythe is very predictable and gives Dazzle plenty of time to react with Shallow Grave: Dazzle just has to keep a close eye on his allies below 50% health.
* However, Dazzle must be sure to use Shadow Wave on that ally immediately after, or they will die from 
Heartstopper Aura when the Shallow Grave ends!
Necrophos
* Viper does large amounts of magic damage over time, meaning that if a Necrophos uses Ghost Shroud, Viper's abilities will greatly reduce Necrophos survivability, and may actually kill him.
* By the same token, Viper can use his 
Viper Strike on Necrophos if he attempts to heal himself with Ghost Shroud, and depending on any other effects Necrophos may have from him, (IE:
Poison Attack,
Corrosive Skin), Viper can often kill Necrophos while he is in his Ghost Shroud.
* Viper's Corrosive Skin helps him take reduced damage from all of Nercophos spells that deal magical damage, which is Necrophos's only source of damage.
Additional:
* 
Nethertoxin prevents Heartstopper Aura from dealing damage or healing Necrophos.
* Viper's magic damage is amplified whenever Ghost Shroud is used.
* Corrosive Skin makes Viper tankier against Death Pulse and Reaper's Scythe.
Necrophos
* Necrophos's Ghost Shroud does not prevent Muerta from attacking him while she uses 
Pierce the Veil, while making Necropohos even more vulnerable.
* Necrophos's Heartstopper Aura does very little to Muerta due to her quickly bursting down Necrophos and having a small health pool.
Necrophos
* Ursa can do damage very fast with his 
Overpower and 
Fury Swipes abilities, Necrohops will have taken large amounts of damage before he can use Ghost Shroud, And if Ursa has 
Skull Basher, Ursa will quickly demolish Necrophos before he can do anything to retaliate.
* Skilled and smart Ursa can bait Necrophos into using Reaper's Scythe on him, and with his 
Aghanim's Scepter upgraded 
Enrage that can negate 80% of the damage, Ursa will often survive and waste Reaper's Scythe.
Necrophos
* Mana Shield can tank most of the damage from Reaper's Scythe; with sufficient mana, the kill threshold drops significantly.
* Necrophos has a movement speed equal to Medusa, and is easy to chase down with a slowing item in Medusa's inventory.
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.
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
Additional:

Necrophos
* Necrophos struggles at clearing away durable illusions or summons. Meepo can overwhelm Necrophos with his many duplicates, especially in the later stages of the game, and his 
Earthbind will prevent Necrophos from getting away, even if he casts Ghost Shroud.
* Meepo's high burst damage from 
Poof can make it difficult for to Necrophos to stay alive, and as Necrophos excels in extended fights, he will not be able to do as much damage as he intends to.
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
Ember Spirit
* Sleight of Fist boosted by Battle Fury and 
Daedalus makes quick work of Meepo if clones are crowded around each other.
* 
Searing Chains interrupts Meepo's initiating because Meepo's clones do not have spell immunity.
Additional:
* 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.
Necrophos
* Heroes who possess abilities that can save targets from being killed by Reaper's Scythe: Abaddon, Bane, Outworld Destroyer, Shadow Demon, Omniknight, etc.
Additional:
* If he isn't silenced, Abaddon can use Borrowed Time to escape Reaper's Scythe during the delay.
Necrophos
* Any hero with a low HP pool is easy for Tinker to nuke down: 
Crystal Maiden, 
Enchantress, 
Gyrocopter, Lion, Riki, 
Techies, 
Terrorblade, Necrophos, 
Invoker.
Necrophos
* Heroes who possess abilities that can save targets from being killed by Reaper's Scythe: Abaddon, Bane, Outworld Destroyer, Shadow Demon, Omniknight, etc.
Necrophos
* Heroes with one single-target abilities such as 
Wraith King, Necrophos, or Doom will struggle against Weaver's Linken Sphere.
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.
Ember Spirit
* Heroes who rely on high mobility are especially vulnerable to Primal Roar: Storm Spirit, Ember Spirit, Queen of Pain.
Necrophos
* Using Reaper's Scythe against Wraith King is a bad idea for Necrophos as his Reincarnation can waste it. And when upgraded with Aghanim's Scepter it can delay the deaths of allies.
Additional:
* Reaper's Scythe can't kill Wraith King while Reincarnation is off cooldown
* In the laning stage Vampiric Spirit can out-heal the slow {tooltip:DoT|Damage over Time} from Heartstopper Aura.
Necrophos
* Heroes who rely on physical damage are easily negated by Ghost Shroud: Phantom Assassin, Wraith King, 
Juggernaut.
Necrophos
* Ghost Shroud can not protect and easy transpierce from 
Lucent Beam and 
Eclipse. Since Her's build Aghanim's Scepter, Ghost Shroud impossible protect and when Eclipse activated discharge Lucent Beam.
Additional:
* Even though Luna has a hard time laning against Necrophos, his Ghost Shroud won’t protect him in teamfights because it will increase the damage from Lucent Beam and Eclipse.
* Luna is a natural 
Black King Bar wielder, and none of Necrophos's spells can bypass spell immunity outside of Heartstopper Aura.
Necrophos
* 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.
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.
Necrophos
* Heroes that have small health pools and little to no escape mechanisms are even easier prey for Necrophos. Ghost Shroud's slow will allow him to catch him with them, and get nuked down with his abilities, even preventing retaliation due to Reaper's Scythe's stun. Such heroes include Crystal Maiden, 
Witch Doctor, 
Warlock or 
Shadow Fiend.
Necrophos
* If Rubick steals Reaper's Scythe, he can turn the powerful ultimate back against Necrophos's team. Even his other spells are useful in Rubick's hands, giving him a sustain or a weak initiation/protection tool.
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.
Necrophos
* Reaper's Scythe can kill Terrorblade quickly before he has chance to use 
Sunder because it instantly disables an enemy hero on which it's casted.
* Even if Terrorblade succeeds to use Sunder on Necrophos, Necrophos can still protect himself from Terroblade's high attack damage with Ghost Shroud and 
Death Seeker from 
Aghanim's Shard, which can turn him ethereal and prevent Terrorblade from attacking him. Ghost Shroud also amplifies any healing Necrophos receives for it's duration, which in combination with Death Pulse allows Necrophos to easily nullify Sunder's effects while Death Seeker can be used to disarm Terrorblade and amplify any magical damage he will take.
* Necrophos often buys 
Radiance, which combined with Death Pulse can help him deal with Terrorblade's illusions from 
Conjure Image and 
Manta Style. Death Seeker from Aghanim's Shard can also spread on Terrorblade's illusions upon impact.
* Terrorblade depends entirely on physical attacks and his damage output is 100% physical. Therefore, since he has no any sources of magical damage output and hates going for items that deal magical damage like Dagon, Ethereal Blade and 
Revenant's Brooch, Ghost Shroud will render him unable to damage Necrophos at all.
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.
* 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.
Necrophos
* Reaper's Scythe can kill Alchemist before Chemical Rage has the time to heal him.
* Ghost Shroud can prevent Alchemist from attacking Necrophos, as well as make him immune to Acid Spray and Unstable Concoction damage.
* Heartstopper Aura will do damage as long as Necrophos is alive based on health percentage, which is a problem for a strength hero such as Alchemist.
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.
Necrophos
* Death Pulse can easily wipe out Broodmother's spiderlings if they're too close while also offering Necrophos a source of regeneration for Broodmother's harass in lane.
* Ghost Shroud prevents Broodmother or her spiderlings from damaging Necrophos temporarily until Broodmother buys 
Nullifieror Revenant's Brooch.
* Heartstopper Aura will regenerate lost health and mana for every spiderling or spiderite Necrophos manages to kill.
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.
Necrophos
* Heroes that have escape abilities (such as Queen of Pain, Storm Spirit or Timbersaw) can be either nullified by Reaper's Scythe or a complimentary item for Necrophos (like 
Rod of Atos or Scythe of Vyse). If Necrophos is quick enough and enters range, they can quickly, if not instantly, die if they are not quick enough.
Additional:
* Heartstopper Aura effectively negates Timbersaw's large HP pool as well as HP regen.
* Death Pulse together with health and mana regeneration from killed creeps helps Necrophos and his teammates survive Timbersaw's burst damage.
* As a tanky hero that stays in the middle of teamfights, Timbersaw is an easy target for Reaper's Scythe.
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.
Necrophos
* Necrophos usually doesn't build itmes that give attack damage, minimalizing effects of Static Link.
* He can use Ghost Shroud to prevent Razor from attacking him with the stolen damage from Static Link.
* Razor is somewhat vulnerable to magical damage, and Reaper's Scythe prevents him from escaping with his high movement speed when things get dangerous.
Ember Spirit
* Any hero with teleport abilities (e.g. Ember Spirit, Storm Spirit) can easily break Static Link.
Necrophos
* Heroes that have small health pools and little to no escape mechanisms are even easier prey for Necrophos. Ghost Shroud's slow will allow him to catch him with them, and get nuked down with his abilities, even preventing retaliation due to Reaper's Scythe's stun. Such heroes include Crystal Maiden, Witch Doctor, Warlock or Shadow Fiend.
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.
Necrophos
* Heartstopper Aura is effective against high health heroes, and Pudge is no exception. Coupled with his self-damage from Rot, being around Heartstopper Aura could prove risky for Pudge.
* Regardless of how much health Pudge gains through Flesh Heap, Reaper's Scythe will often kill Pudge should his health fall below 40%, making Necrophos an ideal counter versus Pudge.
Additional:
* No matter how high Pudge builds up strength with his 
Flesh Heap, all it needs is for him to fall below a certain percentage of health for him to fall to Reaper's Scythe. Considering his constant self-damage with 
Rot, being around Heartstopper Aura will prove risky for an overconfident Pudge.
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.
Necrophos
* Heroes with area heals prevents Bloodseeker from bringing enemies low, and therefore deny him his Thirst bonuses and health return: Necrophos, 
Dazzle
Ember Spirit
* Fire Remnant allows Ember Spirit to escape while Ruptured.
Additional:
* Fire Remnant allows Ember Spirit to escape Bloodseeker while 
Ruptured.
Necrophos
* Death Pulse and Ghost Shroud very effective against her physical damage.
* Heartstopper Aura and Reaper's Scythe are very effective against tanky Strength hero Marci.
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.
Necrophos
* Heroes that have small health pools and little to no escape mechanisms are even easier prey for Necrophos. Ghost Shroud's slow will allow him to catch him with them, and get nuked down with his abilities, even preventing retaliation due to Reaper's Scythe's stun. Such heroes include Crystal Maiden, Witch Doctor, Warlock or Shadow Fiend.
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.
Necrophos
* Heartstopper Aura can do a decent damage overtime to Chen's High-Health-Creep Army, and Chen does not have any source of burst damage to fight back against Necrophos.
* Skilled Necrophos can purchase a 
Spirit Vessel to provide an AOE debuff that can reduce the healing from 
Divine Favor and 
Hand of God.
* Necrophos often builds Radiance, which combined with Death Seeker from Aghanim's Shard allows him to quickly clear Chen's creeps.
* Necrophos can often kill Chen's allies with Reaper's Scythe before Chen can save them with Hand of God.
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.
Necrophos
* Necrophos' largely magical damage completely ignores Bulwark.
* Ghost Shroud protects Necrophos from God's Rebuke but more importantly stops Mars from being a threat in lane.
Necrophos
* Reaper's Scythe will turn Tiny's high health against him.
* Heartstopper Aura does substantial damage to Tiny as a result of his high max health.
* Ghost Shroud protects Necrophos from Tiny's physical damage with Tree Grab and Tree Volley.
Necrophos
* Reaper's Scythe and Heartstopper Aura deal percentage-based damage, ignoring Underlord's high health.
* Ghost Shroud protects Necrophos from Underlord's damage from Atrophy Aura, and also amplifies all the healing Necrophos receives.
Necrophos
* No matter how Tidehunter builds tanky items such as (
Guardian Greaves, 
Crimson Guard or 
Pipe of Insight), all it needs is for him to fall below a certain percentage of health for him to fall to Reaper's Scythe.
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.
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.
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.
Ember Spirit
* Ember Spirit burns quickly 
Refraction thanks to its own Flame Guard, which is why it can interrupt Templar Assassin, giving its team the opportunity to quickly kill her
* Ember Spirit dodges a blow from 
Meld his own Sleight of fist, which can be a big problem for her in a 1-on- 1 fight
* 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:
* 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
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
* 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.
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.
Necrophos
* Frequent healing from Death Pulse and 
Mekansm makes it difficult for Axe to finish off targets with Culling Blade.
* Ghost Shroud's instant cast time allows Necrophos to turn ethereal before being initiated on by Berserker's Call. This prevents him from attacking Axe while taunted, thus lowering the chance to proc Counter Helix.
* Axe's high health is relatively ineffective against Heartstopper Aura's percentage-based health degeneration.
* Reaper's Scythe stops Axe's game plan of using Berserker's Call multiple times and since he's in the middle of the fight, this spell is very easy to grab kills onto him.
Additional:
* Frequent healing from Death Pulse makes it difficult for Axe to finish off targets with 
Culling Blade.
* Reaper's Scythe negates Axe's tankiness, and can kill him quickly after initiation if Axe's health is low enough.
* Heartstopper Aura can be very effective against Axe due to Axe's high strength gain.
* However, bear in mind that 
Berserker's Call can prevent Necrophos from using his Ghost Shroud to defend his fragile self from physical damages. And Heartstopper Aura can unintentionally help Axe to trigger his 
Counter Helix more frequently while also hurting Necrophos with 
Blade Mail during activation.
* Nonetheless Heartstopper Aura is not considered as a normal attack, thus it will not trigger Counter Helix, so anyone who wrote the statement above should be awarded with MVP and considered a TI champion purely for the innovation of new mechanics.
Ember Spirit
* Flame Guard makes Dark Seer not deal any damage with his skills to Ember Spirit.
Necrophos
* Phoenix constantly depletes its own health due to the health costs of its abilities. Unlike heroes that have a similar mechanic, Phoenix does not benefit from low health, nor does it really have a countermeasure for it. As such, Phoenix is a very vulnerable target for Necrophos to prey on, especially when caught off guard before it can cast 
Supernova.
Additional:
* Necrophos becomes a bigger threat the lower one's health gets, and unfortunately for Phoenix, most of its spells have noticeable health costs. Those costs, coupled with his Heartstopper Aura, means that staying in a teamfight for too long under Necrophos' presence will make Phoenix a more valid target for his ultimate, with its stun completely preventing any form of retaliation or protection. Necrophos players are also likely to buy more durability items such as 
Hood of Defiance, making him more able to withstand Phoenix's damage despite having no escape mechanisms.
* However, it is also important to remember that a Scepter-upgraded Supernova can help protect an ally from his ultimate.
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.
Necrophos
* Necrophos is a dangerous opponent to go against with. Regardless of how much strength Undying has gained from Decay, Necrophos can finish off Undying with Reaper's Scythe once Undying's HP falls below a certain threshold.
* Heartstopper Aura will do more damage to Undying if he gained strength from Decay, as it does damage based on a hero's maximum health.
Ember Spirit
* 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.
Additional:
* 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.
Necrophos
* Frequent healing from Death Pulse and Mekansm/Guardian Greaves or Pipe of Insight makes it difficult for Earthshaker to execute his combo with Echo Slam.
* Necrophos usually buys Radiance to improve their burning aura damage from Heartstopper Aura will usually disable Earthshaker's Blink Dagger prior to a teamfight, preventing him from initiating or re-initiating.
* Reaper's Scythe allows to kill Earthshaker while he blinks in, preventing him from executing his combo (although Earthshaker is rarely a primary target).
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.
Necrophos
* Heroes who rely on physical damage are easily negated by Ghost Shroud: Phantom Assassin, Wraith King, Juggernaut.
Necrophos
* Heroes who thrive on teamfights can be a problem, such as Venomancer, Necrophos, 
Centaur Warrunner...
Additional:
* His Heartstopper Aura deals the same gradual damage over time no matter how high Sven builds his strength or health pool up, and should he fall down to a certain percentage, his high health will no longer matter if Necrophos manages to land his Reaper's Scythe, killing him instantly. But it is best if Necrophos can either catch him off guard before he can possibly use his Black King Bar (which is an item Sven players commonly purchase), or bait him out of it.
* Ghost Shroud prevents Sven from hitting Necrophos, and if he doesn't have his 
Storm Hammer available, it could make him completely immune to Sven and allow Necrophos to easily kite him around.
Necrophos
* Necrophos's Reaper's Scythe can finish off a low-health Morphling.
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.
Necrophos
* Heroes that have escape abilities (such as Queen of Pain, Storm Spirit or Timbersaw) can be either nullified by Reaper's Scythe or a complimentary item for Necrophos (like Rod of Atos or Scythe of Vyse). If Necrophos is quick enough and enters range, they can quickly, if not instantly, die if they are not quick enough.
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.
Necrophos
* Heroes with wide AoE abilities will reveal Monkey King through Mischief: Necrophos, 
Phoenix, 
Alchemist, 
Earthshaker, 
Razor, 
Tinker, Leshrac, Queen of Pain
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
Necrophos
* Heroes that have high health but little to no magic resistance are easy prey for Necrophos, as no matter how high they build their health up, Reaper's Scythe will kill them outright as long as they fall under a certain threshold, and Heartstopper Aura will deal the same amount of damage regardless, decaying their health the longer they stay within range. As such, Strength heroes like Chaos Knight, Centaur Warrunner or 
Magnus are good targets for his ultimate.
Ember Spirit
* Heroes with high mobility will be able to avoid Gyrocopter's area attacks: Storm Spirit, 
Morphling, Ember Spirit
Necrophos
* Heroes that have high health but little to no magic resistance are easy prey for Necrophos, as no matter how high they build their health up, Reaper's Scythe will kill them outright as long as they fall under a certain threshold, and Heartstopper Aura will deal the same amount of damage regardless, decaying their health the longer they stay within range. As such, Strength heroes like Chaos Knight, Centaur Warrunner or Magnus are good targets for his ultimate.
Additional:
* With high health and rarely buying Linken's Sphere or Black King Bar, Centaur Warrunner is a good target for Reaper's Scythe. However, Centaur Warrunner can resolve this problem by buying Hood of Defiance and it's upgrade Pipe of Insight to diminish its damage.
* Heartstopper Aura will do well against high health heroes such as Centaur Warrunner.
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 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.
Necrophos
* Heroes that have small health pools and little to no escape mechanisms are even easier prey for Necrophos. Ghost Shroud's slow will allow him to catch him with them, and get nuked down with his abilities, even preventing retaliation due to Reaper's Scythe's stun. Such heroes include Crystal Maiden, Witch Doctor, Warlock or Shadow Fiend.
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.
Necrophos
* Illusions make it difficult for Necrophos to target his Reaper's Scythe correctly, thus giving illusion heroes like Chaos Knight or Naga Siren an edge against Necrophos.

As such, Strength heroes like Chaos Knight, Centaur Warrunner or Magnus are good targets for his ultimate.
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.
Necrophos
* Enemies that possess high defenses through magic resistance, damage reduction, or high regeneration will make it difficult to whittle their health down to get to Reaper's Scythe's threshold. Such heroes include 
Bristleback (although only from behind), 
Spectre, Ursa, and 
Dragon Knight.
Necrophos
* Heartstopper Aura and Reaper's Scythe go right through Dragon Knight's armor.
Necrophos
* Enemies that possess high defenses through magic resistance, damage reduction, or high regeneration will make it difficult to whittle their health down to get to Reaper's Scythe's threshold. Such heroes include Bristleback (although only from behind), Spectre, Ursa, and Dragon Knight.
Necrophos
* Heartstopper Aura deals percentage-based damage flagged as HP removal, so it is not reduced by 
Bristleback, nor does it trigger passive 
Quill Sprays.
* Reaper's Scythe is very effective against Bristleback not only due to its percentage-based damage, but rather because it first stuns and then deals its damage, allowing Necrophos to position in front of Bristleback in time.
Additional:
* Reaper's Scythe and Heartstopper Aura deal percentage-based damage, ignoring Bristleback's high health.
* Heartstopper Aura's HP removal does not trigger Bristleback's passive.
Necrophos
* Enemies that possess high defenses through magic resistance, damage reduction, or high regeneration will make it difficult to whittle their health down to get to Reaper's Scythe's threshold. Such heroes include Bristleback (although only from behind), Spectre, Ursa, and Dragon Knight.
Necrophos
* Death Pulse can single out Spectre from her illusions, as well as heal his team against her. He also usually stands close to his allies for Death Pulse, effectively disabling 
Desolate.
Necrophos
* Blade Fury blocks the damage done by Death Pulse and Reaper's Scythe. Additionally, Ghost Shroud decreases Necrophos's magic resistance, making him take more damage from Blade Fury.
Necrophos
* Heroes who rely on physical damage are easily negated by Ghost Shroud: Phantom Assassin, Wraith King, Juggernaut.
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.
Ember Spirit
* Ember Spirit cannot use his Activate Fire Remnant to escape while under effect from 
Doom.
Necrophos
* 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.
Necrophos
* 
Disruption can save an ally from a fatal Reaper's Scythe.
* 
Demonic Purge can remove Ghost Shroud, making Necrophos vulnerable to physical damage and preventing him from regenerating health.
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
* 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.
Necrophos
* Heroes that have escape abilities (such as Queen of Pain, Storm Spirit or Timbersaw) can be either nullified by Reaper's Scythe or a complimentary item for Necrophos (like Rod of Atos or Scythe of Vyse). If Necrophos is quick enough and enters range, they can quickly, if not instantly, die if they are not quick enough.
Necrophos
* Laguna Blade deals amplified magical damage (pure from Aghanim's Scepter) to Necrophos when he is under the effects of Ghost Shroud.
Additional:
* 
Laguna Blade's damage as well as damage from all of Lina's abilities will be greatly amplified during Ghost Shroud.
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

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.
Necrophos
* Diffusal Blade is a core item on Phantom Lancer. And when combined with his numerous illusions, it allows him to rapidly deplete Necrophos's mana, rendering Necrophos incapable of doing anything.
* It can be difficult to single out the true Phantom Lancer among his army, giving Necrophos a hard time with aiming his ultimate.
* Even if his illusions are defeated, Phantom Lancer can simply create more of them at his disposal with almost no issues.
Ember Spirit
* 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.
Additional:
* Sleight of Fist is the natural counter to Phantom Lancer's army of illusions, especially when combined with Battle Fury.
Necrophos
* Necrophos' Ghost Shroud increases the magic damage taken by Necrophos.
* If Zeus builds both an Ethereal Blade and 
Veil of Discord, it almost always guarantees a kill.
Ember Spirit
* 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
Additional:
* 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.
Ember Spirit
* 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

In all cases, Ember Spirit will go into negative
Necrophos
* Huskar is often at low health, making him easy prey for Reaper's Scythe.
* Ghost Shroud prevents Huskar from stacking Burning Spear, and if Heartstopper Aura stacks are active, can regenerate health lost to existing stacks.
Additional:
* Because Huskar tends to stay at low health to gain the maximum bonuses from Berserker's Blood, it makes him an exceptionally prime target for Reaper's Scythe.
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

Necrophos
* Ghost Shroud can be use both offensively to slow Lone Druid or Defensively to prevent Lone Druid and The Spirit Bear from attacking him.
* Heartstopper aura burns the Spirit bear High HP over time. Additionally, it can deal decent damage to Lone Druid during his True Form.
