* Heroes who cannot escape from Trample early might be easy first blood. Heroes like Witch Doctor and Omniknight should play very cautiously alone...

* Heroes with strong area-of-effect damaging and/or disabling abilities will be able to intercept Underlord and his team when they exit from Fiend's Gate: Luna's Aghanim's Scepter upgraded Eclipse, Dawnbreaker's Solar Guardian, Axe's Berserker's Call, Mars's Arena of Blood, Jakiro's Macropyre, Dual Breath and Ice Path, Naga Siren's Song of the Siren, Razor's Eye of the Storm and Plasma Field, Lina's Light Strike Array, Broodmother's Spinner's Snare from Aghanim's Scepter, Elder Titan's Earth Splitter and Echo Stomp, Alchemist's Unstable Concoction and Acid Spray, Queen of Pain's Sonic Wave, Dark Seer's Wall of Replica and Vacuum, Venomancer's Noxious Plague and Poison Nova from Aghanim's Scepter, Oracle's Fortune's End and Rain of Destiny from Aghanim's Shard, Bloodseeker's Blood Rite, Enigma's Black Hole and Midnight Pulse, Shadow Fiend's Requiem of Souls, Batrider's Aghanim's Scepter upgraded Flaming Lasso, Firefly, Flamebreak and Sticky Napalm, Ancient Apparition's Ice Blast, Sand King's Epicenter, Sand Storm and Burrowstrike, Gyrocopter's Call Down, Ember Spirit's Sleight of Fist, Death Prophet's Exorcism and Silence, Monkey King's Wukong's Command, Crystal Maiden's Freezing Field, Muerta's The Calling, Medusa's Stone Gaze, Zeus's Nimbus from Aghanim's Scepter. Dark Willow's Bramble Maze, Pangolier's Swashbuckle, Grimstroke's Soulbind, Ink Swell and Stroke of Fate, Earthshaker's Echo Slam and Fissure, Puck's Dream Coil and Waning Rift, Winter Wyvern's Winter's Curse, Magnus's Reverse Polarity.

* 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.

* 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.

* 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.

* 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.

* Sprout gets destroyed by Trample and Onslaught.

* 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

* Terrorblade has no stun and is vulnerable to Primal Beast's spell comboes due to his low health points in the laning stage and mid game.
* Reflection can be dispelled using Primal Beast's level 15 left talent.
* Sunder is the only real threat Terrorblade has against Primal Beast but he may die before he can even use it.

* 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.

* Primal Beast has a massive healthpool making it very difficult to get through it with a nuke such as Eclipse or Lucent Beam.
* Primal Beast is faster than Luna, as one of her main ways to escape danger, is very problematic for her in the laning stage especially.
* His ultimate goes through debuff immunity, making Luna's Black King Bar less effective.
* Primal Beast commonly buys Blade Mail which is a big problem for a single target bursting hero like Luna.

* 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.

* Primal Beast has multiple ways to cancel Life Drain very quickly.
* Pugna has a very low strength gain and as a support does not have much gold to buy health items, making him vulnerable to Primal Beast's onslaught of magical damage.
* Ironically, Decrepify actually just increases Primal Beast's damage on the targeted ally if Trample is activated. However, it can be used to slow him down and prevent any further Trample damage.

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

* Dark Pact, Shadow Dance and Depth Shroud will do nothing against Onslaught and Trample, as they are both ground area-of-effect spells.
* Primal Beast has a gigantic hitbox, which could be difficult for Slark to escape with Pounce should Primal Beast choose to block him. Pounce also does not completely prevent Primal Beast from trampling offensively, as he still has some room to move.
* Primal Beast has a huge health pool making it difficult to shed it with Essence Shift and may allow Primal Beast to build Uproar stacks against him very rapidly.
* If Primal Beast buys an Aghanim's Scepter he can also break Essence Shift from working on attacks which is a big part of Slark's damage output.

* 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.

* Phantom Assassin is known to be weak against bursts of magical damage, something Primal Beast excels at from the beginning of the game. He can use this to his advantage by constantly hunting Phantom Assassin down, especially if she is left alone to farm.
* Primal Beast is a good carrier of Ethereal Blade, Vanguard and Shiva's Guard all of which are very good against Coup de Grace and Phantom Strike.
* Even though Primal Beast does a lot of physical damage early on, later once Blur becomes more potent, she may find herself being overwhelmed by Trample and Onslaught instead.
* Primal Beast's ultimate goes through spell immunity and his level 25 talent makes it even more devistating against Phantom Assassin.
* Primal Beast can dispel Stifling Dagger and any attack modifers it applies with his left level 15 talent.

* 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.

* Any hero with low mobility and max healthsuch as Silencer, Crystal Maiden etc.

* Heroes who can continue dealing damage even while being stunned: Luna, Razor, Axe, Bristleback, Leshrac, Death Prophet, Jakiro.

* Heroes who rely on burst damage with magical damage will struggle to kill Primal Beast: Spirit Breaker, Gyrocopter, Leshrac

* 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

* Long lockdown is a great way to deal with Axe to prevent Berserker's Call from being used, heroes such as Legion Commander, Beastmaster and Primal Beast are good examples of this.

Additional:
* Berserker's Call will be a stun for Primal Beast and not much else due to Trample making him unable to attack.
* Battle Hunger is neglitable because Primal Beast has a much bigger health than Axe, so he does not need to fear being slowed, or his other abilities including Counter Helix or even a Blade Mail.
* Getting Primal Beast low enough to use a successful Culling Blade can be very difficult due to his massive health advantage over most heroes.
* Not ability related but Primal Beast does not need to fear Axe in lane, as Trample, combined with Uproar and Onslaught will do a ton of damage even if Axe has a Vanguard.

* 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.

* Pierce the Veil does not prevent Primal Beast from using any of his spells to their fullest and is one of the few heroes that can disable her during her ultimate and a common Black King Bar purchase. She will also likely be fatal to herself if Primal Beast has a Blade Mail active.
* Gunslinger will be disabled if Primal Beast buys an Aghanim's Scepter.

* 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 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.

* Primal Beast is one of Sniper's greatest counters, as he has no real means of escape and is very squishy, especially in the early game. Sniper's potshots and Shrapnel can contribute to Primal Beast's Uproar and further make him tankier than he already is. Onslaught allows him to close the gap on Sniper at his own volition, and Trample can deal serious damage to his meager health pool.

* Dispersion reduces damage based on a percentage, which is very minimal against large amounts of small instances of damage such as Trample. It reduces each tick by about 14 at the maximum level, which is very small.
* Desolate is never a threat to Primal Beast due to his large health pool and Uproar is still out-damaging the ability.
* Onslaught can allow Primal Beast to chase Spectre fleeing with Spectral Dagger, as both skills phase through trees and terrain.
* Primal Beast can also dispel Spectral Dagger's slow with his left level 15 talent, making it completely useless against him.
* Primal Beast excels at early aggression, pushing weak carries out of lane and farming areas he wants to control. Overall just not a pleasant matchup for Spectre.
* Should Primal Beast buy an Aghanim's Scepter he can also break both passive abilities.

* 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.

* Onslaught prevents all of Razor's abilities from being effective against him, especially in the laning stage.

* 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.

* Exorcism kills Primal Split's units very quickly.

* Primal Beast can use Uproar to tank a portion of Omnislash, making him much more likely to survive it. Primal Beast can also charge away from Omnislash using Onslaught as the spell ends.
* Blade Fury will never do more damage than Uproar once the stacks are activated.
* Primal Beast is very commonly buying items that are good against Juggernaut, such as Ethereal Blade and Heart of Tarrasque.
* Primal Beast has one of the few ultimates that can prevent Juggernaut from spinning away with a teleport.

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

* 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.

* 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'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.

* While Broodmother can hide in the trees with Spin Web, Primal Beast's ability to trample trees down can give him an edge in catching her.
* Insatiable Hunger will not do much vs Primal Beast's onslaught of disables.
* While Silken Bola can slow Primal Beast down, it's not enough to stop Trample from doing more damage than Broodmother can do back.
* Spawn Spiderlings will be destroyed by Onslaught and Trample very easily.

* 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.

* Any hero who lanes very poorly will struggle with Primal Beast's potential snowball in the very early levels, like Keeper of the Light, Luna, Templar Assassin...

* Illusion heroes will struggle against Primal Beast's area damage capability, such as Chaos Knight, Naga Siren, Terrorblade.

* Heroes who rely on burst damage with magical damage will struggle to kill Primal Beast: Spirit Breaker, Gyrocopter, Leshrac

* 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

* 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.

* Illusion heroes will struggle against Primal Beast's area damage capability, such as Chaos Knight, Naga Siren, Terrorblade.

* Any hero who lanes very poorly will struggle with Primal Beast's potential snowball in the very early levels, like Keeper of the Light, Luna, Templar Assassin...

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

* 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.

* Heroes who have low or high armor but very high health will be difficult for drow to burst down quickly: Primal Beast, Axe, Centaur Warrunner.

* Any hero with low mobility and max healthsuch as Silencer, Crystal Maiden etc.

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

* Heroes who cannot escape from Trample early might be easy first blood. Heroes like Witch Doctor and Omniknight should play very cautiously alone...

* Heroes who rely on burst damage with magical damage will struggle to kill Primal Beast: Spirit Breaker, Gyrocopter, Leshrac

* Heroes that are hard to gank: Axe, Death Prophet, Phantom Lancer, Slark, Centaur Warrunner, Bristleback, Medusa, Mars.

* 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.

* 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.

* 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.

* Special mention to Lifestealer who can use Rage to prevent Trample damage, but Primal Beast's ultimate can still be casted during the spell.

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

* Hard carries who just want to farm and be left alone will not appreciate Primal Beast, heroes such as Medusa, Drow Ranger...

* 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.

* 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.

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

* Since Primal Beast is highly mobile with Onslaught alone, he will be difficult to catch with both Cold Feet and Ice Blast.
* Ice Blast is less effective due to Primal Beast's massive health pool and resistance to taking damage.
* While Chilling Touch can be used to slow Primal Beast briefly, it is not enough to beat him back, and can also contribute to his Uproar stacks.
* Primal Beast has a dispel talent at level 15 that will remove Cold Feet immediately when Uproar is used.

* 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:
* 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.

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

* 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.

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

* Heroes with unorthodox escapes will struggle against Primal Beast, such as Nature's Prophet, Tinker, and Templar Assassin.
