Death Prophet
* 
Guardian Angel nullifies the physical damage from Exorcism during teamfights. And when upgraded with 
Aghanim's Scepter, it also prevents Death Prophet from pushing towers. However, Death Prophet can partially counter this issue with 
Eul's Scepter of Divinity, a common item on Death Prophet.
* 
Heavenly Grace dispels 
Silence.
Additional:
* 
Exorcism's damage is blocked by Guardian Angel.
* Heavenly Grace can dispel Silence allies if Omniknight is able to cast it.
Magnus
* Any hero who can counter-initiate in anticipation without getting caught in Reverse Polarity: 
Sven, 
Omniknight, 
Enigma, 
Luna, 
Naga Siren, 
Mars, 
Jakiro, 
Venomancer, 
Elder Titan, 
Faceless Void, 
Rubick, 
Keeper of the Light, 
Pugna, 
Invoker, 
Spectre, 
Alchemist, 
Treant Protector, 
Lina, 
Oracle, 
Zeus, 
Shadow Shaman, 
Phoenix, 
Razor, 
Huskar, 
Batrider, 
Kunkka, 
Tidehunter, 
Wraith King, 
Sand King, 
Medusa, 
Dawnbreaker.
Death Prophet
* Heroes with strong team-fight abilities (especially ultimates) like Tidehunter, 
Brewmaster, 
Death Prophet, etc.
Magnus
* All of Magnus's spells are perfect for Rubick to steal, especially Reverse Polarity for a counter-initiation.
* 
Telekinesis is one of the best instant-disables in the game, completely ruining Magnus's initiation.
Additional:
* 
Reverse Polarity, if stolen, can counter-initiate 
Magnus's team and put them at a huge disadvantage.
* Magnus himself is positioned at the center of teamfight after casting Reverse Polarity, and will be stunned by Rubick's stolen one most of the times.
* Bear in mind that Magnus will usually cass 
Skewer or 
Shockwave after he casts the ultimate, so the time windows left for steal can be short.
* Shockwave allows Rubick to farm fast, and also deals decent AoE damage in teamfights.
* 
Empower can be casted on the carry (especially affective if melee) on Rubick's team to accelerate their farm or amplify their damage in fights.
* Skewer could be used to displace enemy or escape from danger.
* Telekinesis can relocate the enemy in front of Rubick for Skewer.
* With Quick Cast enabled, Rubick can stop the enemy Magnus with careful prediction using Telekinesis to interrupt 
Horn Toss - Skewer combo.
Death Prophet
* Heroes that can kill Death Prophet with nukes can prevent her from using Exorcism to its full duration or using it at all: Lina, 
Lion, 
Puck, 
Morphling.
Magnus
* 
Illusory Orb serves as a good scouting tool whenever Magnus is hiding in the trees, allowing Puck to warn its allies and disrupt his initiation attempts.
* 
Phase Shift allows Puck to dodge Shockwave when timed correctly.
* Even after Magnus successfully uses Reverse Polarity and Skewer Puck's teammates, Puck can usually counter-initiate using both 
Waning Rift and 
Dream Coil.
* Magnus cannot use Skewer when he is affected by Dream Coil, making him vulnerable to follow-up disables.
* Puck usually gets its own 
Blink Dagger as well, which makes it harder to lock down unless Magnus commits Reverse Polarity only for Puck.
Death Prophet
* Heroes that depend on disrupting fights with ability combos or big ultimate abilities are vulnerable to the long stun of Fiend's Grip: 
Disruptor, Death Prophet, Enigma, Faceless Void, Invoker, 
Lich, Magnus, Mars, Medusa, 
Outworld Destroyer, Phoenix, Puck, 
Queen of Pain, 
Shadow Fiend, Treant Protector, 
Underlord, 
Winter Wyvern, 
Witch Doctor, Zeus.
Magnus
* Heroes that depend on disrupting fights with ability combos or big ultimate abilities are vulnerable to the long stun of Fiend's Grip: Disruptor, Death Prophet, Enigma, Faceless Void, Invoker, Lich, Magnus, Mars, Medusa, Outworld Destroyer, Phoenix, Puck, Queen of Pain, Shadow Fiend, Treant Protector, Underlord, Winter Wyvern, Witch Doctor, Zeus.
Death Prophet
* Heroes that can kill Death Prophet with nukes can prevent her from using Exorcism to its full duration or using it at all: Lina, Lion, Puck, Morphling.
Magnus
* Any hero who can counter-initiate in anticipation without getting caught in Reverse Polarity: Sven, Omniknight, Enigma, Luna, Naga Siren, Mars, Jakiro, Venomancer, Elder Titan, Faceless Void, Rubick, Keeper of the Light, Pugna, Invoker, Spectre, Alchemist, Treant Protector, Lina, Oracle, Zeus, Shadow Shaman, Phoenix, Razor, Huskar, Batrider, Kunkka, Tidehunter, Wraith King, Sand King, Medusa, Dawnbreaker.
Magnus
* Tinker can break Magnus's Blink Dagger using 
March of the Machines and 
Heat-Seeking Missile, therefore delaying any initiation or making Magnus use Skewer or 
Force Staff to initiate. His {Ability ID:Defense Matrix|Tinker} will decrease the duration of Reverse Polarity and can also be cast on all of his teammates with {Ability ID:Rearm|Tinker}. Tinker usually gets his own Blink Dagger as well, which makes him harder to lock down unless Magnus commits Reverse Polarity only for Tinker.
Magnus
* Treant Protector can usually scout out Magnus in the trees with 
Eyes in the Forest and disrupt his initiation attempts. He can also counter Magnus' initiation with 
Overgrowth.
Magnus
* Even if Wraith King dies after Magnus disables him, Magnus' entire team will be slowed and vulnerable for counter-initiation.
Death Prophet
* 
God's Strength allows Sven to take down Death Prophet quickly, reducing the damage dealt over time from Exorcism.
* 
Warcry's bonus armor and movement speed is very useful for Sven and his teammates against Exorcism, which deals physical damage.
Magnus
* Any hero who can counter-initiate in anticipation without getting caught in Reverse Polarity: Sven, Omniknight, Enigma, Luna, Naga Siren, Mars, Jakiro, Venomancer, Elder Titan, Faceless Void, Rubick, Keeper of the Light, Pugna, Invoker, Spectre, Alchemist, Treant Protector, Lina, Oracle, Zeus, Shadow Shaman, Phoenix, Razor, Huskar, Batrider, Kunkka, Tidehunter, Wraith King, Sand King, Medusa, Dawnbreaker.
Magnus
* Sven is very vulnerable to chain stun such as Lion, Shadow Shaman or Magnus.
Death Prophet
* 
Duel is a great initiation to kill Death Prophet before she can cast Exorcism. Furthermore, Legion Commander often builds 
Blade Mail and can reflect Exorcism's damage to kill Death Prophet easily.
Magnus
* 
Rupture deals extra damage to Magnus during Skewer or Force Staff, preventing him from escaping or counter-initiating, forcing him to invest on a 
Linken's Sphere.
Magnus
* Magnus has very mediocre damage against Alchemist, because he can survive the stun duration of Reverse Polarity with 
Chemical Rage.
Magnus
* Disruptor can disable Magnus's Blink Dagger using 
Thunder Strike during a considerable duration, disrupting his initiation attempts.
* 
Glimpse brings Magnus back after he escapes with Skewer and/or Force Staff.
* 
Static Storm if used on a fight can prevent Magnus from using Reverse Polarity after he jumps in.
Death Prophet
* Ice Blast prevents Death Prophet from gaining health from 
Spirit Siphon and Exorcism.
Additional:
* 
Ice Blast prevents Death Prophet from gaining health from Spirit Siphon and Exorcism.
* However, there is a way for Death Prophet to counter Ice Blast: Since Death Prophet is not healed until the spirits are returned to her. She can attempt to outrun her spirits to delay their return until Ice Blast duration runs out.
Magnus
* 
Plasma Field can slow Magnus during Skewer, and when combined with 
Eye of the Storm, will potentially disable his Blink Dagger, preventing him from initiating.
* 
Static Link drains the bonus damage from Empower. However, it can be broken by Skewer and/or Force Staff.
* 
Storm Surge gives Razor and his allies high mobility needed to avoid Shockwave & Reverse Polarity.
Magnus
* Magnus is not tanky and struggles against burst damage, something Primal Beast excels at in the early-to-mid game. Primal Beast is also able to out-damage Magnus's Empower and can even contribute to his Uproar stacks.
* Using Skewer to drag Primal Beast while he is trampling will count as movement and will trigger a rapid number of slams, which could prove lethal to Magnus.
Death Prophet
* Death Prophet has a high mana pool and due to her heavy reliance on her spells, she will be a prime target for 
Mana Void.
* Death Prophet has less mobility than Anti-Mage due to 
Blink.
Magnus
* Heroes who build mana boosting items but have low mana regeneration are especially vulnerable against Mana Break and Mana Void: 
Timbersaw, 
Slark, Shadow Fiend, 
Clinkz, 
Bristleback 
Nyx Assassin, Magnus
Additional:
* Anti-Mage can survive against Magnus's Reverse Polarity thanks to the high magic resistance from 
Counterspell.
* Should Anti-Mage survive Magnus's Reverse Polarity and Skewer, Magnus will have exhausted most of his skills and items, preventing him from defending himself against any counter initiation or a follow-up from a blink escape.
* 
Mana Break can deplete Magnus's much needed mana.
* Anti-Mage's Blink will make him a very hard target or Magnus to use Reverse Polarity on, having to solo ult him later on in the game or leave him out of the Reverse Polarity.
* Overall, any attempt for Magnus to gank Anti-Mage will hurt him more than it will hurt Anti-Mage.
Death Prophet
* In early to mid stage, Silence is also a great way to counter escape oriented heroes such as 
Anti-Mage, Queen of Pain, and 
Phantom Assassin to prevent them from escaping, provided that they don't have any basic dispels.
Magnus
* Magnus cannot manfight Huskar even with Empower, 
Berserker's Blood's high attack speed and health regeneration, combined with Huskar's high health and 
Burning Spear stacks will allow Huskar to kill Magnus before he can kill him.
* From a safe distance, Huskar can surprise and counter Magnus's initiation with 
Life Break and Burning Spear.
* Burning Spear also deals damage over time, disabling Blink Dagger and preventing him from initiating or escaping.
Magnus
* Spectre disables Magnus' Blink Dagger using her ultimate, and later into the game can usually outlive Reverse Polarity's duration.
Additional:
* Spectre can use 
Haunt to intercept and disrupt Magnus's initiation attempts.
* 
Spectral Dagger can severely slow down Magnus after he uses Skewer.
* Magnus often travels alone when he is trying to initiate, so 
Desolate can be very effective against him.
* In late game, Spectre can survive Reverse Polarity initiation thanks to 
Dispersion.
Magnus
* Similar to Night Stalker, Venomancer can simultaneously scout Magnus hiding in trees and put Blink Dagger on cooldown with 
Plague Ward, which gives Magnus problems when trying to blink in and initiate.
Additional:
* Venomancer can simultaneously scout Magnus hiding in trees and putting Blink Dagger on cooldown with Plague Wards, which makes Magnus real problems to blink and initiate.
Death Prophet
* 
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.
Magnus
* Any hero who can counter-initiate in anticipation without getting caught in Reverse Polarity: Sven, Omniknight, Enigma, Luna, Naga Siren, Mars, Jakiro, Venomancer, Elder Titan, Faceless Void, Rubick, Keeper of the Light, Pugna, Invoker, Spectre, Alchemist, Treant Protector, Lina, Oracle, Zeus, Shadow Shaman, Phoenix, Razor, Huskar, Batrider, Kunkka, Tidehunter, Wraith King, Sand King, Medusa, Dawnbreaker.

Magnus
* With Aghanim's Scepter, Broodmother will gain access to 
Spinner's Snare, which will allow her to create invisible lines on her webs from 
Spin Web that will root, deal damage over time, and reveal enemy heroes if they unwittingly step on them. This allows Broodmother to keep her allies alerted on heroes who rely on invisibility-themed and movement-themed abilities and items to surprise enemy heroes and disrupt ganking attempts of enemy heroes: Phantom Assassin, Nyx Assassin, 
Mirana, 
Bounty Hunter, 
Templar Assassin, 
Riki, 
Spirit Breaker, Anti-Mage, 
Tusk, 
Ursa, 
Nature's Prophet, Enigma, 
Void Spirit, Magnus etc.

Magnus
* Any hero who can survive Magnus's initiations and manfight him: Huskar, Faceless Void, 
Weaver, 
Abaddon, 
Troll Warlord, Alchemist, 
Dragon Knight, 
Night Stalker, 
Viper.
Additional:
* Most of Magnus's abilities except Empower will trigger damage through 
Corrosive Skin.
* 
Poison Attack and 
Viper Strike can slow Magnus during Skewer, as well as putting his Blink Dagger on cooldown, preventing him from initiating or re-initiating.
Magnus
* Any hero who can survive Magnus's initiations and manfight him: Huskar, Faceless Void, Weaver, Abaddon, Troll Warlord, Alchemist, Dragon Knight, Night Stalker, Viper.

Death Prophet
* Riki is another good hero to shutdown Death Prophet with 
Diffusal Blade as his core item. His 
Smoke Screen stops her from initiating and casting spells.
Magnus
* 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.
Magnus
* Any hero who can survive Magnus's initiations and manfight him: Huskar, Faceless Void, Weaver, Abaddon, Troll Warlord, Alchemist, Dragon Knight, Night Stalker, Viper.
Magnus
* Any hero who can counter-initiate in anticipation without getting caught in Reverse Polarity: Sven, Omniknight, Enigma, Luna, Naga Siren, Mars, Jakiro, Venomancer, Elder Titan, Faceless Void, Rubick, Keeper of the Light, Pugna, Invoker, Spectre, Alchemist, Treant Protector, Lina, Oracle, Zeus, Shadow Shaman, Phoenix, Razor, Huskar, Batrider, Kunkka, Tidehunter, Wraith King, Sand King, Medusa, Dawnbreaker.
Death Prophet
* Heroes that can kill Death Prophet with nukes can prevent her from using Exorcism to its full duration or using it at all: Lina, Lion, Puck, Morphling.
Magnus
* Any hero who can counter-initiate in anticipation without getting caught in Reverse Polarity: Sven, Omniknight, Enigma, Luna, Naga Siren, Mars, Jakiro, Venomancer, Elder Titan, Faceless Void, Rubick, Keeper of the Light, Pugna, Invoker, Spectre, Alchemist, Treant Protector, Lina, Oracle, Zeus, Shadow Shaman, Phoenix, Razor, Huskar, Batrider, Kunkka, Tidehunter, Wraith King, Sand King, Medusa, Dawnbreaker.
Magnus
* Heroes that have an escape that doesn't disjoint projectiles: Mirana, Faceless Void, Magnus
Magnus
* 
Dark Ascension reduces vision for the enemy team, which makes it more difficult for Magnus to initiate with Blink Dagger and Reverse Polarity. It is also more likely that Night Stalker will scout out Magnus with Aghanim's Scepter and a 
Gem of True Sight, after which he can silence Magnus with 
Crippling Fear.
Death Prophet
* Heroes that can punish aggressive heroes, such as: 
Leshrac, 
Shadow Demon, Pugna, Death Prophet.
Magnus
* Phoenix will usually be on the sidelines or further back ready to use 
Sun Ray. Even after Magnus successfully uses Reverse Polarity and skewer Phoenix's teammates, Phoenix can usually counter-initiate using all of its abilities.
Death Prophet
* Silence (and mana burns) will be a persistent problem for Phoenix, as it is heavily reliant on its abilities whether defensively or offensively, so heroes like Death Prophet, 
Skywrath Mage, and even Nyx Assassin must be closely observed to prevent being shut down by these heroes.
* Hexes are a greater threat to Phoenix as they also disable items, preventing Phoenix from dispelling the debuff on its own.
Magnus
* Jakiro's abilities deal damage over time, which can disrupt Magnus's attempts to initiate with Blink Dagger and Reverse Polarity.
* 
Macropyre not only disables Blink Dagger for a considerable duration, but can also destroy Trees, revealing Magnus's cover and position.
Death Prophet
* Heroes with good counter-push abilities to clear creep waves can hinder Jakiro's early pushing ability: Death Prophet, 
Sniper, 
Tinker, 
Windranger.
Death Prophet
* 
Shadowraze (Near), 
Shadowraze (Medium), and 
Shadowraze (Far) can hit hard in the early stages of the game, and due to Shadow Fiend's high attack damage, most of Death Prophet's last hits will be denied in the laning phase. Additionally, 
Requiem of Souls can deal massive damage or kill Death Prophet at the start of team fights in combination with Eul's Scepter of Divinity or 
Shadow Blade.
Magnus
* Squishy core heroes (Shadow Fiend, Sniper, etc)
Magnus
* If Luna can use 
Eclipse in anticipation, Magnus will be killed before he can even manages to cast Reverse Polarity.
* Aghanim's Scepter upgraded Eclipse is a very good counter-initiation tool against Magnus when he casts Reverse Polarity, granted as long as Luna can cast it from safe distance.
Death Prophet
* 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.
Magnus
* Zeus can easily find Magnus who is often hiding in the trees with 
Thundergod's Wrath and 
Lightning Bolt, which allows him to warn allies and disrupt his initiation attempts.
Death Prophet
* Spirit Siphon does a lot of magical damage, especially in the early game. This allows her to demolish low health heroes such as Zeus, Pugna, especially when combined with her other spells.
Magnus
* 
Shrapnel can sometimes scout out Magnus and also place his Blink Dagger on cooldown. Aside from that, Sniper likes to stay far back behind enemy lines, so it's difficult to catch him with Reverse Polarity unless you already have vision on him and can Skewer him to the rest of his team.
Magnus
* Squishy core heroes (Shadow Fiend, Sniper, etc)
Death Prophet
* Silence will prevent Chen from activating 
Hand of God.
* 
Crypt Swarm and Exorcism can clear Chen's creeps and heavily damage Chen.
* Spirit Siphon heavily damages Chen and slows him, while healing Death Prophet.
Additional:
* Silence will prevent Chen from activating Hand of God.
* Crypt Swarm and Exorcism can clear Chen's creeps and heavily damage Chen.
* Spirit Siphon heavily damages Chen and slows him, while healing Death Prophet.
Magnus
* Heroes with strong area-of-effect damage can make quick work of Chen's converted creeps and at same time gain farm: Magnus, Jakiro, Shadow Fiend, Kunkka, Luna, Dragon Knight, Medusa, Alchemist.
Death Prophet
* Exorcism's ghosts will automatically clear all Proximity Mines revealed when Death Prophet walks near them, provided that the ghosts do not have a specific target at that time.
* Death Prophet is a natural Eul's Scepter of Divinity carrier, meaning she can easily escape a Blast Off initiation.
Magnus
* Heroes with forced movement abilities or non-interrupting forced movement, such as Lion, 
Drow Ranger, Magnus, Mars, as they can cancel blast-off mid air, removing his ability to initiate or escape.
Death Prophet
* Crypt Swarm helps clear waves of Treants.
* Silence prevents Nature's Prophet from using Sprout or Teleportation.
* Exorcism kills Treants with ease.
Additional:
* Crypt Swarm helps clear waves of Treants.
* Silence prevents Nature's Prophet from using Sprout or Teleportation.
* Exorcism kills Treants with ease.
Magnus
* Heroes who rely on illusions and spawns (Chaos Knight, 
Beastmaster, Nature's Prophet, Enigma etc.).
Death Prophet

Magnus
* Empower helps Magnus' allies clear out illusions.
* Reverse Polarity and Skewer will pull Phantom Lancer along with his illusions, and reposition them together for easy nuking.
* Shockwave deals significant area damage in the early game,destroys phantoms and may even indicate the real Phantom Lancer.
Magnus
* Skewer and Reverse Polarity will often push Monkey King out of Wukong's Command.
Magnus
* Using Reality Rift sets up a Reverse Polarity on Chaos Knight and his illusions.
* Shockwave and Skewer kill Phantasm's illusions quickly, as can Empower cast on a melee carry.
Additional:
* All Magnus abilities are very good against Chaos Knight's 
Phantasm illusions.
Death Prophet
* Because Timbersaw relies heavily on his spells to deal damage, Silence can easily disable him in a team fight.
* Exorcism's spirits do not count as regular attacks, and will not add stacks of 
Reactive Armor.
Death Prophet
* Exorcism kills Primal Split's units very quickly.
Death Prophet
* Death Prophet's Crypt Swarm and Spirit Siphon can repetively damage Earthshaker, preventing him from using Blink Dagger.
* Silence can be used to silence Earthshaker after he blinks in with Blink Dagger, preventing him from executing his combo.
* Spirits from Exorcism are completely invulnerable and cannot interact with anything at all, which will greatly weaken damage from Echo Slam. This can put Earthshaker in a serious disadvantage against Death Prophet.
Magnus
* Meepo is vulnerable to area damage and disables from Magnus himself as well as his team through Empower.
Death Prophet
* Spirit Siphon exploits her naturally high HP to deal a good amount of DPS. She may break the link with Rebound, but Silence covers that problem.
* Marci's poor armor makes her vulnerable to Exorcism.
Death Prophet
* Spirit Siphon can deal some serious damage to Clockwerk while he is in 
Power Cogs while healing Death Prophet in process. Exorcism can also be used to take down Clockwerk faster while he is in Power Cogs.
* Death Prophet usually buys a 
Hurricane Pike or Eul's Scepter of Divinity which allows her to easily escape from Power Cogs or save her allies from Clockwerk.
* Silence can prevent Clockwerk from using his ablities during teamfight, especially since Clockwerk is an easy target for it while in Power Cogs.
Additional:

Death Prophet
* Death Prophet's Silence allows her to prevent Bounty Hunter from escaping with Shadow Walk.
* If Bounty Hunter cannot escape with Shadow Walk while affected by Silence, she will be able to burst him down with Crypt Swarm and Spirit Siphon.
Additional:
* Death Prophet's Silence allows her to prevent Bounty Hunter from escaping with Shadow Walk.
* If Bounty Hunter cannot escape with Shadow Walk while affected by Silence, she will be able to burst him down with Crypt Swarm and Spirit Siphon.
Magnus
* Reverse Polarity pierces through 
Rage, wasting part of it's duration.
* Magnus is tanky and mobile, making it hard for Lifestealer to focus and kill him in all stages of a game.
Magnus
* Heroes with AoE abilities are a bane to Beastmaster's summons: 
Storm Spirit, Magnus, Pangolier.
Death Prophet
* Because Exorcism's damage is not reduce by damage block abilities or items, Death Prophet can be very good against heroes who rely on armor to survive: Axe, 
Terrorblade, Morphling, Dragon Knight
Magnus
* Any long duration disables that can pierce through both, Pierce The Veil and 
Black King Bar are devastating against Muerta: Enigma's Black Hole, Dawnbreaker's Solar Guardian, Axe's Berserker's Call, Naga Siren's Aghanim's Scepter upgraded 
Ensnare and 
Reel In from Aghanim's Scepter, Jakiro's Aghanim's Scepter upgraded Macropyre,

Fiend's Grip, 
Pudge's 
Dismember, Batrider's Flaming Lasso, Beastmaster's 
Primal Roar, Grimstroke's Soulbind, Medusa's Stone Gaze, Magnus's Reverse Polarity.
Magnus
* Heroes with other kind of disables that pierce spell immunity can hold Pangolier in place during Rolling Thunder: Axe, Beastmaster, Enigma, Magnus, Pudge, Batrider, Bane, Winter Wyvern
Death Prophet
* In the same vein, heroes with silences — especially with the AoE ones like Death Prophet's Silence — can also prevent Crystal Maiden from being able to impact a fight.
Death Prophet
* Any heroes with stuns or silences: Death Prophet, Lion, Shadow Shaman, Skywrath Mage
Death Prophet
* In early to mid stage, Silence is also a great way to counter escape oriented heroes such as Anti-Mage, Queen of Pain, and Phantom Assassin to prevent them from escaping, provided that they don't have any basic dispels.
Additional:
* Silence will prevent Queen of Pain from using Blink to escape or chase.
* If Queen of Pain uses Blink to close the gap to Death Prophet, Death Prophet will be in range for Spirit Siphon and typically gain an advantage over Queen of Pain.
Death Prophet
* Heroes who can continue dealing damage even while being stunned: Luna, Razor, Axe, Bristleback, Leshrac, Death Prophet, Jakiro.
Death Prophet
* Heroes who can silence will shut down Dark Willow entirely: Death Prophet, 
Silencer, Drow Ranger
Death Prophet
* Heroes that are hard to gank: Axe, Death Prophet, 
Phantom Lancer, Slark, Centaur Warrunner, Bristleback, Medusa, Mars.
Death Prophet
* Windranger heavily relies on her abilities for any form of tactical advantage and damage. A well timed silence will make her useless: Puck,Silencer, Death Prophet, Skywrath Mage, Drow Ranger, 
Earth Spirit, Grimstroke.

* In early to mid stage, Silence is also a great way to counter escape oriented heroes such as Anti-Mage, Queen of Pain, and Phantom Assassin to prevent them from escaping, provided that they don't have any basic dispels.
Death Prophet
* Because all of Warlock's abilities are active abilities, silences can make his impact in fights minimal. Be cautious of heroes that carry silences like Death Prophet, Puck, and the aforementioned Silencer.
Magnus
* Any hero who can counter-initiate in anticipation without getting caught in Reverse Polarity: Sven, Omniknight, Enigma, Luna, Naga Siren, Mars, Jakiro, Venomancer, Elder Titan, Faceless Void, Rubick, Keeper of the Light, Pugna, Invoker, Spectre, Alchemist, Treant Protector, Lina, Oracle, Zeus, Shadow Shaman, Phoenix, Razor, Huskar, Batrider, Kunkka, Tidehunter, Wraith King, Sand King, Medusa, Dawnbreaker.
Death Prophet
* Heroes who can clear the waves of Enigma's Eidolons: Lina, Luna, Dawnbreaker, Jakiro, Shadow Shaman, Death Prophet, Keeper of the Light, Invoker, Leshrac, Puck.
Magnus
* Long ranged disables, especially those that pierce spell immunity, cancel Black Hole: Beastmaster's Primal Roar, Bane's Fiend's Grip, Faceless Void's 
Chronosphere, Magnus's Reverse Polarity, Axe's Berserker's Call, Pudge's
Meat Hook.
Death Prophet
* Death Prophet is able to Silence Undying up to 6 seconds. Besides, due to Undying's high strength during a team fight, Spirit Siphon is a powerful ability against Undying thanks to the percentage health drain.
Death Prophet
* Any heroes with silences can negate the majority of Outworld Destroyer's damage output: Death Prophet, Night Stalker, Drow Ranger, 
Doom .
Death Prophet
* Lich is heavily reliant on his abilities to contribute to team fights, so be wary of enemies that can Silence: Bloodseeker, Death Prophet, Silencer, Drow Ranger, Skywrath Mage.
Death Prophet
* Because Exorcism's damage is not reduce by damage block abilities or items, Death Prophet can be very good against heroes who rely on armor to survive: Axe, Terrorblade, Morphling, Dragon Knight
Magnus
* Heroes with cleave or multi-target attacks can quickly take on Familiars and reduce Visage's firepower like Gyrocopter, Kunkka, Magnus and Medusa.
Death Prophet
* Heroes that can kill Death Prophet with nukes can prevent her from using Exorcism to its full duration or using it at all: Lina, Lion, Puck, Morphling.
Death Prophet
* While Morphling can burst her down with 
Adaptive Strike (Agility), Death Prophet does have tools to disrupt him. A Morphling affected by Silence makes it unable to use 
Attribute Shift (Strength Gain) to increase its health pool or use 
Waveform to escape.
Magnus
* Any hero who can counter-initiate in anticipation without getting caught in Reverse Polarity: Sven, Omniknight, Enigma, Luna, Naga Siren, Mars, Jakiro, Venomancer, Elder Titan, Faceless Void, Rubick, Keeper of the Light, Pugna, Invoker, Spectre, Alchemist, Treant Protector, Lina, Oracle, Zeus, Shadow Shaman, Phoenix, Razor, Huskar, Batrider, Kunkka, Tidehunter, Wraith King, Sand King, Medusa, Dawnbreaker.
Death Prophet
* Quas-Exort Invoker is also a good matchup due to the fact he has no 
Wex to run faster due to the movement impairment on his stealth. The 
Forge Spirit and 
Cold Snap combo doesn't harm her as well since you can drain Invoker's HP with Spirit Siphon which forces him to retreat.
* Silence also prevents Invoker from using 
Invoke or casting his main spells temporarily. There is no way Invoker can block it unless he has Eul's Scepter of Divinity to cyclone himself or has help from allies.
Magnus
* Any hero who can counter-initiate in anticipation without getting caught in Reverse Polarity: Sven, Omniknight, Enigma, Luna, Naga Siren, Mars, Jakiro, Venomancer, Elder Titan, Faceless Void, Rubick, Keeper of the Light, Pugna, Invoker, Spectre, Alchemist, Treant Protector, Lina, Oracle, Zeus, Shadow Shaman, Phoenix, Razor, Huskar, Batrider, Kunkka, Tidehunter, Wraith King, Sand King, Medusa, Dawnbreaker.
Death Prophet
* Kraken Shell neither dispels nor provides damage reduction against Spirit Siphon. This ability also drains health based on percentage damage, making Tidehunter's large healthpool a very appealing target. Furthermore, the health gained from the Siphon is independent from the amount of damage dealt, so Death Prophet will always heal a large amount of from Tidehunter's pool even if Tidehunter has magic reduction items or abilities on him, which makes her an untargetable enemy for you as this easily outweights any damage output you can provide.
* Exorcism is yet another ability from which Kraken Shell provides no useful protection, as the spirits completely ignore the damage block and are unaffected by the dispel. This ability also creates an unfriendly area where your blink will be constantly cancelled, reducing your ability to land a good Ravage.
* Ravage does not stop neither Spirit Siphon nor Exorcism, making the ability mostly ineffective against her. Additionally, Death Prophet usually builds Eul's Scepter of Divinity, which can be used to dodge the stun entirely.
Magnus
* Heroes who take a long time to become strong are in for a rough mid game, such as Outworld Destroyer, Magnus, Medusa, and Anti-Mage.
Death Prophet
* Spirit Siphon and Exorcism can damage through his 
Resonant Pulse shields.
* Silence can prevent Void Spirit escape or contributing much in fights.
Magnus
* Any hero who can counter-initiate in anticipation without getting caught in Reverse Polarity: Sven, Omniknight, Enigma, Luna, Naga Siren, Mars, Jakiro, Venomancer, Elder Titan, Faceless Void, Rubick, Keeper of the Light, Pugna, Invoker, Spectre, Alchemist, Treant Protector, Lina, Oracle, Zeus, Shadow Shaman, Phoenix, Razor, Huskar, Batrider, Kunkka, Tidehunter, Wraith King, Sand King, Medusa, Dawnbreaker.
Death Prophet
* Death Prophet is a terrible Flaming Lasso target if Exorcism has already been used, since it can still damage Batrider and his teammates, but if Batrider manages to Lasso her before that, it can lead to Death Prophet being quickly burst down.
Magnus
* Any hero who can counter-initiate in anticipation without getting caught in Reverse Polarity: Sven, Omniknight, Enigma, Luna, Naga Siren, Mars, Jakiro, Venomancer, Elder Titan, Faceless Void, Rubick, Keeper of the Light, Pugna, Invoker, Spectre, Alchemist, Treant Protector, Lina, Oracle, Zeus, Shadow Shaman, Phoenix, Razor, Huskar, Batrider, Kunkka, Tidehunter, Wraith King, Sand King, Medusa, Dawnbreaker.

Death Prophet

Death Prophet
