* Heartstopper Aura is effective against high health heroes, and Pudge is no exception. Coupled with his constant self-damage from Rot, being around Necrophos could prove risky for an overconfident 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.

* Shukuchi grants Weaver invisibility and a high degree of mobility for a short time, which can make Weaver a difficult target to hook.
* The Swarm with Desolator can remove Pudge little natural armor and makes it difficult to remove Weaver's beetles, due to his low base attack time and poor agility. Additionally, The Swarm can scout out Pudge's location.
* Given that Pudge only has one reliable disable in Dismember, should Weaver survive, Weaver can simply use Time Lapse (or target allies with Aghanim's Scepter) to remove the damage entirely.
Additional:
* While Weaver is in Shukuchi, Rot doesn't slow him and Meat Hook is easy to avoid.
* Even when hooked, Weaver can use Time Lapse, negating both the damage and displacement.
* Pudge has low armor and low attack speed, making him susceptible to The Swarm and physical attacks.
* Dismember is easy to block with Linken's Sphere and it's the only way to break Weaver's Linken Sphere.
* However, the long duration stun of Dismember can be dangerous for Weaver.

* Geminate Attack works on Tombstone, allowing Weaver to kill it quickly.
* Zombies attacking Weaver disappear once he goes invisible with Shukuchi.
* Undying has no way to catch a mobile Weaver.

* Necrophos is a dangerous opponent to go against with. Regardless of how many 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.

* Shukuchi can break Static Link with little trouble.
* Time Lapse can easily be used to avoid damage from Plasma Field and can recover the damage done from Static Link and Eye of the Storm.
* Eye of the Storm can't kill bugs from The Swarm.

* Necrophos usually doesn't build much attack damage to steal from.
* 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.

* Some heroes, such as Necrophos can be an issue if not initiated onto by Sven first.

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.

* Sven can be easily kited since Weaver is a natural Linken's Sphere carrier and Sven relies on Storm Hammer to disable and kill a hero.

* 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.

* Heroes who often build Linken's Sphere: Weaver, Morphling, Medusa.

* 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 Necrophos.
* Necrophos can purchase a Spirit Vessel to provide an AOE debuff that reduce the healing from Divine Favor and Hand of God.

* Invisibility heroes can sneak past Chen's creeps and pick him off: Nyx Assassin, Weaver, Bounty Hunter Riki.

* Reaper's Scythe can kill Terrorblade quickly before he has chance to use Sunder.
* Ghost Shroud protects Necrophos against Terrorblade's high attack damage.

* Heroes, whose core item builds includes Monkey King Bar: Faceless Void, Windranger, Weaver, Juggernaut.

* 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.

* In general, Timbersaw struggles against highly mobile heroes that can avoid his abilities: Puck, Weaver, Ember Spirit and others.

* 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.

* Weaver's Shukuchi allows him to escape from Warlock's Upheaval with maximum move speed.
* His ultimate Time Lapse allows him to ignore damage from {U:Warlock Golem} and escape.

* Shukuchi gets Weaver in front of Bristleback, negating the protection from the Bristleback passive.
* Weaver's mana break talent depletes Bristleback's mana pool, preventing him from spamming abilities.

* 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.
Additional:
* 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.

* 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.

* Any hero who can survive Magnus's initiations and manfight him: Huskar, Faceless Void, Weaver, Abaddon, Troll Warlord, Alchemist, Dragon Knight, Night Stalker, Viper.

* Heroes that are hard to kill without lockdown: Puck, Weaver.

* 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.

* 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.

* Brewmaster is slow and has low armor, making his laning stage very difficult against Geminate Attack.
* Apart from the slow moving Hurl Boulder, which can be disjointed, he has no control to catch Weaver.

* Heroes with good escapes can usually outmaneuver and escape from Spectre: Slark, Clinkz, Weaver

* 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.

* Shukuchi allows Weaver to close the gap between himself and Sniper with high speed, and to maneuver through teamfights to get on top of him.
* A combination of The Swarm and Desolator tears through Sniper's low armor.

* 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.

* The Swarm is not blocked by Rage and can be used to lower Lifestealer's already low armor, making him even more vulnerable to physical damage.
* Shukuchi renders the Open Wounds slow pretty useless, as it gives Weaver maximum movement speed, allowing him to escape or kite around Lifestealer.
* However, Weaver is a common Linken's Sphere carrier to block and Time Lapse to dispel Open Wounds.
Additional:
* Open Wounds's slow is ignored by Shukuchi.
* Lifestealer has no other lockdown and relies on being on top of enemies; Weaver can kite him with ease.

* 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 Pipe of Insight or Hood of Defiance to diminish its damage.
* Heartstopper Aura will do well against high health heroes such as Centaur Warrunner.

* Time Lapse with Aghanim's Scepter dispels Flaming Lasso when used on allied hero.
* Linken's Sphere is core item for a Weaver making him a hard target for Lasso during entire game.

* Weaver doesn't care much about Lich's slows thanks to Shukuchi.
* If he sees Chain Frost is targeting him, he can easily isolate himself with Shukuchi so that it stops bouncing around.
* Unless Lich bursts Weaver immediately, Lich has no hard disables or silences to prevent him from using Time Lapse.

* 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.
Additional:
* 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.

* 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.

* Reaper's Scythe and Heartstopper Aura deal percentage-based damage, ignoring Underlord's high health.

* 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.

* 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.
* Heartstopper Aura will regenerate lost health and mana for every spiderling or spiderite Necrophos manages to kill.

* Heroes with haste can negate Enchant's slow: Weaver, Dark Seer, Lycan, Centaur Warrunner.

* Heroes with magical burst damage can often kill Phantom Assassin before she gets to do much: Necrophos, Nyx Assassin, Gyrocopter.

* Necrophos's Reaper's Scythe can finish off a low-health Morphling.

* 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.

* 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.

* Heroes who can dodge Earth Spirit's abilities: Ember Spirit, Puck, Weaver

* 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.

* Heroes that usually builds Linken's Sphere as a core item: Weaver, Medusa, Morphling, Queen of Pain, Storm Spirit

* 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.
Additional:
* 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.

* Heroes with abilities that reduce armor will make Huskar very vulnerable: Weaver, Dazzle, Bristleback, Vengeful Spirit.

* A well-timed use of The Swarm provides vision over heroes with high mobility: Anti-Mage, Arc Warden, Dark Seer.

* Heroes that can maintain vision on Monkey King can see when he uses Tree Dance: Bloodseeker, Treant Protector with Eyes In The Forest, Sniper, Weaver

* Heroes with wide AoE abilities will reveal Monkey King through Mischief: Necrophos, Phoenix, Alchemist, Earthshaker, Razor, Tinker, Leshrac, Queen of Pain

* Heroes who rely on physical damage are easily negated by Ghost Shroud: Phantom Assassin, Wraith King, Juggernaut.

* Weaver can run away after killing Wraith King once thanks to Shukuchi.
* Wraithfire Blast is quite predictable. If Weaver is quick, he will disjoint it with Shukuchi and proceed to chase Wraith King down.
* Shukuchi does have a fade time. They cannot disjoint it if you use it right next to them. They will be stunned and take damage; however they will still become invisible if they used Shukuchi before the stun hits.
* Weaver can easily harass Wraith King out of his lane thanks to his high base damage and Geminate Attack.
* Weaver can burn Wraith King's mana quickly with his Mana Break or Diffusal Blade, until Wraith King purchases Aghanim's Shard to remove Reincarnation's manacost.
Additional:
* Wraithfire Blast is easy to disjoint with Shukuchi or Time Lapse, and it's the only way to break Weaver's Linken Sphere.
* Wraith King has no other disables and no mobility, allowing Weaver to chase or escape Wraith King as he wishes.
* With the Mana Break talent and Diffusal Blade, Weaver can prevent Reincarnation from triggering until Wraith King has selected the chosen talent.

* A well-timed use of The Swarm provides vision over heroes with high mobility: Anti-Mage, Arc Warden, Dark Seer.

* Heroes with Linken's Sphere as core item: Weaver, Morphling, Medusa.

* Heartstopper Aura and Reaper's Scythe go right through Dragon Knight's armor.

* 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).

* Ursa has no inherent way of disabling a slippery Weaver and prevent him from Shukuchiing or Time Lapseing away, as the slow from Earthshock is useless against Shukuchi's haste effect.
Additional:
* Earthshock's slow is ignored by Shukuchi.
* Ursa can be kited with Shukuchi and his burst damage will be negated with Time Lapse as long as Weaver survives it.
* The Swarm breaks Ursa's Blink Dagger, forcing him to deal with the beetles.

* Escape-type carries: Slark, Storm Spirit, Weaver.

* 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.

* Shukuchi ignores slows and allows Weaver to escape Viper's onslaught.
* Time Lapse dispels Poison Attack and Corrosive Skin and undoes poison damage.
* Weaver's high burst damage allows him to kill Viper before being killed.

* A well-timed use of The Swarm provides vision over heroes with high mobility: Anti-Mage, Arc Warden, Dark Seer.

* 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 negates Axe's tankiness, and can kill him quickly after initiation.
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.
* Heartstopper Aura is effective due to Axe's high strength gain.

* 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.

* 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.

* 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.

* Heroes that rely on slows or low-duration stuns have trouble catching Weaver: Omniknight, Lich.

* Cold Feet is extremely easy to nullify with Shukuchi.
* Ice Vortex does not slow Weaver in Shukuchi.
* Time Lapse will still affect his health, even when hit by Ice Blast.
* Ancient Apparition has no escapes or saves and is very squishy, making him an easy target for Weaver to get on top of.
Additional:
* Time Lapse allows Weaver (or an ally if upgraded with Aghanim's Scepter) to regain HP while affected by Ice Blast.
* Shukuchi completely ignores the slow from Ice Vortex and helps him escape the freeze range of Cold Feet.

* Weaver with Time Lapse
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with Mirror Image
* Omniknight with Heavenly Grace
* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
