* Viper cannot interrupt heroes with powerful channeling abilities: Bane,
Enigma,
Shadow Shaman,
Warlock
* Malefice will prevent Primal Beast from doing anything for a long duration even in the early game when at his strongest.
* Midnight Pulse will scale with his max health so will do a ton of damage combined with any generic stun or Enigma's own abilities.
* Primal Beast relies completely on mobility to do damage, Black Hole makes sure he cannot use any abilities or threaten heroes he is typically good against.
* Viper cannot interrupt heroes with powerful channeling abilities: Bane,
Enigma,
Shadow Shaman,
Warlock
* Like above, supports with reliable stuns can be a massive problem and force Black King Bar in fights unideally, such as
Shadow Shaman,
Lion,
Nyx Assassin.
* Heroes that can drain mana negatively affect Viper's ability to use Poison Attack, Nethertoxin and Viper Strike: Lion,
Anti-Mage
* Like above, supports with reliable stuns can be a massive problem and force Black King Bar in fights unideally, such as
Shadow Shaman,
Lion,
Nyx Assassin.
* Primal Beast's abilities require movement to deal damage, making Rupture potentially deadly and debilitating. Furthermore, its initial damage based on the target's current health is devastating to a full-health Primal Beast with his high strength gain and thus high HP.
* Due to his reliance on spells, Primal Beast is vulnerable to Blood Rite's powerful silence without items to counter it.
* Viper is an agility hero, and his item build mostly includes agility items, so Natural Order can be devastating, removing all armor and greatly decreasing the effectiveness of Corrosive Skin, weakening Viper's magic resistance. Additionally, Echo Stomp and Earth Splitter deal both magical and physical damage, and can help bringing Viper down fast.
* Aghanim's Scepter may be necessary to take Viper down due to
Nethertoxin's break.
* Oracle can negate and shut down Primal Beast simply with Fate's Edict, especially in the early game, as a majority of his damage-dealing spells are magic.
* Oracle can interrupt Primal Beast's Onslaught charge with a well-timed Fortune's End.
* Primal Beast's lethal burst damage combos can be further stalled with False Promise; combined with Fate's Edict and regen from Purifying Flames, Oracle can even completely negate Primal Beast's offense.
Additional:
* Fate's Edict completely negates all of Primal Beast's major damage-dealing spells in the early game and can render Primal Beast useless when cast on a target he is focusing, or in Oracle's defense against Primal Beast himself.
* Fortune's End keeps Primal Beast in place, especially while trampling or in the middle of an Onslaught charge.
* False Promise can interrupt Primal Beast's abilities, as well as further delay Primal Beast from dealing lethal burst damage. In combination with
Fortune's End, Oracle can potentially save an ally from Primal Beast's spell combos.
* Power Cogs keeps Primal Beast pinned down, preventing him from doing damage with Trample. Primal Beast's slow attack speed makes it hard for him to break the cogs and get away. In addition, Power Cogs' knockback is forced movement and thus will intercept Primal Beast's Onslaught if placed well.
* Battery Assault on a lone Primal Beast in the early game effectively keeps him from winding up Onslaught or basic attacking.
* Rocket Flare and
Jetpack (from purchasing
Aghanim's Shard) give Clockwerk many options to scout for Primal Beast, whose kit benefits greatly from ambushing.
* Viper's frailty and low mobility make him an enticing Duel target and Corrosive Skin doesn't protect him against Legion Commander physical attacks.
* Press the Attack can dispel Poison Attack.
* Viper slows can easily negate by Overwhelming Odds movement speed.
* Enfeeble weakens Viper's attack damage, any healing he receives and his cast range, which makes him unable to harass enemy heroes with
Nethertoxin,
Poison Attack and
Viper Strike.
* Brain Sap allows Bane to heavily harass Viper, damaging him while healing Bane, which allows Bane to fight back against Viper's damage over time output, even through debuff immunity from
Black King Bar.
* Viper's Corrosive Skin is useless against Bane as all of his damaging abilities deal Pure damage.
* Viper has no solutions to cancel Fiend's Grip and in addition, he hates buying disabling items like
Eul's Scepter of Divinity.
Additional:
* Enfeeble weakens Viper's attack damage, any healing he receives and his cast range, which makes him unable to harass enemy heroes with Nethertoxin, Poison Attack and Viper Strike.
* Viper's Corrosive Skin is useless against Bane as all of his damaging abilities deal Pure damage.
* Viper has no solutions to cancel Fiend's Grip and in addition, he hates buying disabling items like
Eul's Scepter of Divinity.
* Clinkz does not have any passive abilities at all, making Nethertoxin nearly useless.
* Viper's Corrosive Skin provides no protection against Clinkz's physical damage output.
* Viper is kind of a mixed package. Tinker is very good against him. but stands a better chance against him than most heroes.
* Viper has a high innate magic resistance, but relies on his primary attacks to really deal damage. making Laser an effective way to save allies from him, and deal damage. Keep in mind that his Corrosive Skin will prevent Tinker from blinking.
* Viper's Viper Strike and
Poison Attack will also have a hard time damaging allies through Tinker's constant casting of
Defense Matrix.
* Viper has no solutions to cancel Rearm nor any of Tinker's escape attempts with
Boots of Travel
* However, if Viper gets a jump on Tinker first. Tinker will unlikely survive versus Viper.
* Heroes who can do scaling health damage to Primal Beast are very threatening for the hero. Such as: Phoenix,
Tinker etc.
* Heroes with unorthodox escapes will struggle against Primal Beast, such as Nature's Prophet,
Tinker, and
Templar Assassin.
* Ice Wall and
Ghost Walk can be used to kite and escape from Viper.
* Chaos Meteor and
Sun Strike deal heavy damage and can quickly bring Viper down.
* Cold Snap,
Tornado, and
Deafening Blast are powerful disables that reduce Viper's effectiveness.
* E.M.P. burns Viper's limited mana pool, reducing his potential poison damage.
* Forge Spirits can melt Viper's armor and reduce his durability.
* Invoker's numerous area-of-effect abilities can interrupt Primal Beast, especially while he is in the middle of a team fight, where Primal Beast thrives. (Tornado,
Cold Snap, and
Ice Wall all help to disable Primal Beast and control him from a distance.
* E.M.P. disintegrates Primal Beast's low mana pool.
* However, Invoker is quite a slow-paced hero and not particularly known for being survivable against a rampaging Primal Beast with Black King Bar.
* Corrosive Skin makes Viper receive less damage from Invoker's spells
* Viper can harass Invoker with his Poison Attack in the early game.
* Viper Strike and
Poison Attack can kill Invoker easily if Ghost Walk is on cooldown.
* Ball Lightning allows Storm Spirit to escape through
Viper Strike, wasting Viper's mana.
* It's also very easy to wait out the duration of Nethertoxin's break.
* Viper has no disable, which means he has no way of preventing Morphling from escaping from any of his abilities or keep him inside Nethertoxin.
* Viper is almost exclusively damage over time, which is weak against Morphling due to Attribute Shift (Strength Gain). Additionally, Morphling has no passive abilities, reducing
Nethertoxin's effectiveness against him even further.
* Morphling can turn into Viper himself, allowing him to use any of Viper's abilities against him (excluding Viper Strike). This is particularly bad due to the fact that Viper is already a very slow hero, making
Poison Attack and
Corrosive Skin's slows especially difficult to deal with.
* Soulbind prevents Primal Beast from being able to use Onslaught or his abilities to great effect for a lengthy amount of time.
* Phantom's Embrace is very difficult for Primal Beast to remove due to his slow attack speed and Trample preventing him from attacking.
* Pit of Malice is very good at preventing Primal Beast from entering the fight and stopping Trample damage at all stages of the game.
* Viper Strike can be countered through Snowball, wasting Viper's mana through his ultimate. It's
Viper Strike's break is also useless because he has no passive abilties at all. And to make things worse,
Viper Strike cannot disable
Walrus PUNCH! because it's an auto-cast ability
* As Tusk is a natural Silver Edge wielder, he can use it to disable Viper's magic resistance from
Corrosive Skin, and make him vulnreable to his other allies.
* If Rubick can use Spell Steal to take
Nethertoxin, he will be able to disable
Corrosive Skin, reducing much of Viper's durability.
* He can also steal Viper Strike, which can be used to hinder a hero on your team (or multiple heroes, if Rubick has
Aghanim's Scepter).
* Although Viper Strike cannot be dispelled by Doppelganger, Viper's lack of mobility and AoE damage makes him an easy target for Phantom Lancer.
* Viper's various slows do not work against Phantom Rush.
* Although Phantom Lancer should be wary due to Nethertoxin applying Break.
Additional:
* Phantom Lancer can overwhelm Viper with spawned illusions from Spirit Lance and
Doppelganger. In addition,
Diffusal Blade, a core item on Phantom Lancer, burns Viper's limited mana pool, reducing his potential poison damage.
* Viper's various slows do not work against Phantom Rush. Additionally, it is almost impossible to keep Lancer inside
Nethertoxin's radius in order to disable the passive.
* Time Walk makes it impossible for Primal Beast to stay on top of Faceless Void with his abilities and allows him to heal burst damage dealt to him.
* Once Faceless Void has an Aghanim's Shard, Onslaught can be easily escaped. He could also choose to get a lower cooldown on Time Walk, making it even harder for Primal Beast to catch him in fights or stop his initiations.
* Time Dilation will make Primal Beast useless for an extended time after casting his abilities if he does not have a dispel.
* Chronosphere has many uses such as stopping Primal Beast from casting abilities on him or allies or even on a teammate, since Primal Beast has no way to assist allies trapped within the sphere.
* Supports who can slow him to the point Trample does very little damage in the lane are also not fun: Lich,
Ogre Magi,
Winter Wyvern.
* Primal Beast is mostly played in the offlane role, so picking a carry who can escape from him is essential. Heroes such as Troll Warlord,
Lone Druid and
Outworld Destroyer, or generally any carry with a stun, slow or ability to fight back will stop him from having the good start he needs.
* Ranged heroes will have a hard time hitting enemies inside Magnetic Field: Silencer,
Viper.
* Supports who can slow him to the point Trample does very little damage in the lane are also not fun: Lich,
Ogre Magi,
Winter Wyvern.
* Primal Beast is mostly played in the offlane role, so picking a carry who can escape from him is essential. Heroes such as Troll Warlord,
Lone Druid and
Outworld Destroyer, or generally any carry with a stun, slow or ability to fight back will stop him from having the good start he needs.
* Any ganking heavy support can be a big problem for Primal Beast, such as: Earth Spirit,
Grimstroke before he has a
Black King Bar.
* Viper cannot interrupt heroes with powerful channeling abilities: Bane,
Enigma,
Shadow Shaman,
Warlock
* Primal Beast really suffers against supports he cannot bully in the lane: this includes Dazzle,
Shadow Demon and
Dark Willow since they can use their respective abilities to stop Primal Beast from dealing burst damage, or make it hard for him to stay in range.
* Primal Beast really suffers against supports he cannot bully in the lane: this includes Dazzle,
Shadow Demon and
Dark Willow since they can use their respective abilities to stop Primal Beast from dealing burst damage, or make it hard for him to stay in range.
* Heroes who do not have nor rely on passive abilities make Nethertoxin much less effective: Clinkz,
Pugna,
Nature's Prophet,
Dark Seer,
Lycan,
Tusk
* Heroes who do not have nor rely on passive abilities make Nethertoxin much less effective: Clinkz,
Pugna,
Nature's Prophet,

Tusk
* Primal Beast really suffers against supports he cannot bully in the lane: this includes Dazzle,
Shadow Demon and
Dark Willow since they can use their respective abilities to stop Primal Beast from dealing burst damage, or make it hard for him to stay in range.
* Illusion or summon-based heroes can be a problem to Viper due to his lack of AoE damage: Naga Siren,
Phantom Lancer,
Beastmaster
* Rage ignores all of Viper's magical damage, although
Viper Strike can pierce spell immunity and slows him down.
* Feast and
Open Wounds from
Aghanim's Shard can be combined to heal through Viper's physical damage.
* Aghanim's Scepter upgraded
Infest can be used to disarm Viper, preventing him from using
Poison Attack on Lifestealer's allies.
* Special mention to Lifestealer who can use
Rage to prevent Trample damage, but Primal Beast's ultimate can still be casted during the spell.
* Viper's Nethertoxin cannot disable
Reincarnation, which could put him in disadvantage against Wraith King if his whole team is with him.
* In addition, Viper doesn't like buying Diffusal Blade, which is the only item that can help him against Wraith King.
* Wraith King's high burst damage allows him to kill Viper before being killed.
* Melee heroes with low mobility can be kited and killed by Viper: Treant Protector,
Kunkka,
Alchemist,
Troll Warlord,
Wraith King,
Tiny,
Sven.
* The Keeper of the Light easily farms on the line against the Viper, due to the fact that it has a long-range Illuminate, and the Viper, in turn, cannot use its advantage of dominance on the center line, due to the fact that it does not reach the Keeper of the Light
Additional:
* The Keeper of the Light easily farms on the line against the Viper, due to the fact that it has a long-range Illuminate, and the Viper, in turn, cannot use its advantage of dominance on the center line, due to the fact that it does not reach the Keeper of the Light
* 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...
* Voodoo Restoration heals to counter damage over time of Viper abilities.
* Viper has no way to cancel Death Ward, even through Rod of Atos.
* Heroes who cannot escape from Trample early might be easy first blood. Heroes like Witch Doctor and
Omniknight should play very cautiously alone...
* The ensnare from melee Berserker's Rage can prevent Primal Beast from dealing further Trample damage and can allow Troll Warlord to relentlessly build
Fervor on him.
* Whirling Axes (Ranged) can slow down Primal Beast while trampling and allow Troll Warlord to better control him from range.
* Whirling Axes (Melee) can blind Primal Beast if he attempts to auto-attack Troll Warlord after a fully charged Uproar.
* Battle Trance will make Primal Beast a sitting duck should he be rooted and attacked to death.
* Melee heroes with low mobility can be kited and killed by Viper: Treant Protector,
Kunkka,
Alchemist,
Troll Warlord,
Wraith King,
Tiny,
Sven.
* Naga Siren can easily disjoint, and dispel Corrosive Skin with Mirror Image.
* Since Viper is mostly a single-target hero, he will not have almost any chance against Naga Siren because she is an illusion based hero.
* Viper has no burst damage, so Naga Siren will have plenty of time to use Aghanim's Shard upgraded
Song of the Siren heal her allies before Viper can finish them off.
* Illusion heroes will struggle against Primal Beast's area damage capability, such as Chaos Knight,
Naga Siren,
Terrorblade.
* Windrun evades
Poison Attack and counteracts the slow.
* Viper's low mobility makes him an easy Shackleshot target.
* Focus Fire grants Windranger significant physical damage output to quickly wear Viper down.
* Powershot is a strong harassment and zoning tool against Viper in lane.
* Since Windranger is bad against magical damage, heroes with continuous magical damage or magical nukes can blast her: Zeus,
Tinker,
Leshrac,
Viper,
Skywrath Mage,
Lion,
Lina,
Venomancer.
* Viper Strike breaks Sniper's passives.
* Corrosive Skin allows Viper to deal more damage to Sniper than Sniper deals to him when laning, especially by briefly stepping into Shrapnel.
* Nethertoxin together with
Poison Attack can slow Sniper and tears through his low health and mobility.
* 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.
* Viper's Poison Attack and
Viper Strike that can slow Razor, and is one of the few heroes that can keep him immobile.
* Altogether, Viper's skills reduce Razor's attack speed, heavily reducing the benefit of the damage drain from Static Link.
Additional:
* Storm Surge is counteracted by
Viper Strike, leaving Razor without his extra movement speed.
* Static Link's damage drain doesn't bother Viper a lot as most of his early to mid game damage is magical.
* Onslaught prevents all of Razor's abilities from being effective against him, especially in the laning stage.
* Corrosive Skin minimizes the damage Viper takes from all of Ancient Apparition's abilities.
* Ancient Apparition's slow movement speed, squishy nature, and lack of escape abilities can easily be taken advantage of through Poison Attack and
Viper Strike.
* 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.
* Nethertoxin disable passives, negating Spectre's damage and survivability by removing both
Dispersion and
Desolate.
* Due to Haunt and
Radiance's burn, Spectre is heavily susceptible to being persistently slowed and damaged by
Corrosive Skin without even directly attacking Viper.
* Poison Attack and
Viper Strike further slow Spectre's movement speed to a crawl, while his improved magic resistance means he can easily shrug off
Radiance's burn.
Additional:
* Viper Strike can disable
Desolate and
Dispersion, leaving Spectre with far less damage output and damage mitigation in engagements.
* Spectre is one of the weakest heroes at early levels. Viper can stifle her farm with early fights before Spectre purchases any major items.
* 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.
* The damage over time from Viper's Poison Attack and
Viper Strike rapidly wear down Refraction charges, allowing Templar Assassin to be damaged. Additionally,
Corrosive Skin causes her attacks to apply damage overtime on her as well.
* Nethertoxin is a big threat to Templar Assassin. Her initially low range making it very hard to deal against Nethertoxin in the laning phase. At any stage of the game, a Nethertoxin can always force her to undo her Meld.
Additional:
* All of Viper's abilities quickly burn through Refraction charges.
* Templar Assassin's short range, aside from Psi Blades' spill damage, makes her vulnerable to
Poison Attack harassment.
* Templar Assassin usually buys health and armor items for damage. Outside of Black King Bar, Viper will almost always be able to kill her when
Refraction is 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...
* Heroes with Break abilities will prevent Slark from regenerating and gaining Essence Shift stacks: Viper,
Shadow Demon, etc.
Additional:
* Viper Strike can disable
Essence Shift and the regeneration aspect of
Shadow Dance.
* Dark Pact doesn't mean a lot against Viper's ubiquitous slows.
* Viper becomes a relevant presence in team fights before Slark can procure his standard items (e.g. Shadow Blade).
* 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.
* 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 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.
* Heroes that can apply early pressure before Phantom Assassin has farm are massive threats: Axe,
Viper,
Meepo,
Jakiro,
Pugna,
Slark,
Venomancer etc.
* 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.
* Poison Attack and
Viper Strike slows Axe significantly, and puts his
Blink Dagger on cooldown, preventing him from initiating.
Viper Strike can also break from Counter Helix.
Additional:
* Viper Strike prevents
Counter Helix from triggering, which significantly lowers Axe's damage output in the early to mid game.
* Viper's various slows and damage over time prevents Axe from initiating as well as putting his Blink Dagger on cooldown.
* 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.
* Heroes who can easily harass Crystal Maiden out of lane in the early game (Clinkz,
Viper) can prevent Crystal Maiden from being able to level effectively, and can ultimately slow down her level 6, 12, and 18 to a point where enemy carries already have items to address her ultimate.
* Any hero with low mobility and max healthsuch as Silencer,
Crystal Maiden etc.
* Heroes that can slow Charge of Darkness by a huge amount: Venomancer,
Viper,
Dazzle,
Arc Warden,
Lion,
Huskar,
Shadow Shaman,
Visage,
Undying,
Jakiro.
* Heroes who rely on burst damage with magical damage will struggle to kill Primal Beast: Spirit Breaker,
Gyrocopter,
Leshrac
* Heroes who can harass Omniknight out of lane will keep him weak in the mid game: Viper,
Venomancer,
Clinkz.
* 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 damage-increasing passive abilities, such as Viper and
Riki, will usually kill Silencer in a short time before he even has time to set up his abilities.
* Any hero with low mobility and max healthsuch as Silencer,
Crystal Maiden etc.
* Corrosive Skin will protect Viper from Techies' magical damage.
* Even though Reactive Tazer will disarm Viper if he attacks Techies with Poison Attack, he does lots of damage with his other abilities that can still kill Techies.
* Nethertoxin prevents the buildup of Jingu Mastery stacks.
* Viper's poison magical damage-over-time stops Monkey King from using Tree Dance. It also ignores the extra armor bestowed by Wukong's Command.
Additional:
* Viper STrike prevents the buildup of
Jingu Mastery stacks.
* Monkey King's high base movement speed is of little worth against the array of slows Viper possesses.
* All of Viper's magical damage over time stops Monkey King from using Tree Dance. It also ignores the extra armor bestowed by
Wukong's Command.
* Nethertoxin both Necromastery and Presence of the Dark Lord, reducing his damage massively.
* Corrosive Skin gives Viper bonus Magic Resistance against Shadowraze and Requiem of Souls.
* Viper can easily take advantage of Shadow Fiend's lack of escape and mobility spells with Viper Strike breaks and
Poison Attack. Poison Attack also serves as a great way to harass Shadow Fiend.
* Nethertoxin breaks the damage block from Bulwark.
* Poison Attack and
Viper Strike's slows make it difficult for Mars to contribute to fights due to his low mobility.
Additional:
* Viper Strike can disable
Bulwark entirely, making Mars far less tanky. Using
Nethertoxin inside
Arena of Blood may discourage enemies from following up with Mars's initiation.
* Rod of Atos is currently common on Viper and keeps Mars in position long enough to be killed.
* However, Viper is not very tanky earlier in the game, so positioning against Mars is important for Viper since a well-timed Spear of Mars can be the end of Viper.
* 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.
* The slow applied from Corrosive Skin offsets the movement speed bonus granted by Scorched Earth and the tick-based damage from Infernal Blade and Doom will continually slow Doom down. This allows Viper, much like Sniper, to 'kite' Doom and keep him at a safe distance between the two. Additionally,
Corrosive Skin applies an attack-speed slow which is fairly crippling to a hero such as Doom that, naturally, has a high base attack-time, poor agility gain and builds little attack-speed items.
* Since Doom does not disable auto-cast abilities, Viper's Poison Attack will continue to work. Doom may find it hard to close the distance between himself and Viper, and thusly difficult to effectively lockdown and continually deal damage through his abilities.
* Viper Strike prevents Timbersaw from gaining stacks on Reactive Armor.
* Tiny has low movement speed and attack speed, making him vulnerable to Viper's slows.
* Corrosive Skin provides magic resistance to lower Tiny's magic burst damage.
* Corrosive Skin means Viper can often outlast Venomancer in a battle of attrition.
* Venomancer has no mobility without items, which makes him vulnerable to constant slows.
* In the early game, a Dragon Knight without Black King Bar is basically defenseless against Viper.
* Viper can harass Dragon Knight at any time with his Poison Attack and
Nethertoxin.
* Corrosive Skin reduces damage from Dragon Fire and inflicts damage to him.
* Viper Strike disables Dragon Blood, negating his main survivability.
* Viper Strike and
Poison Attack can severely slow him down even with his Elder Dragon Form.
Additional:
* Dragon Knight is easily harassed by Poison Attack after the laning stage ends.
* Corrosive Skin protects Viper from
Breathe Fire and returns damage.
* Viper Strike can disable
Dragon Blood, Dragon's Knight main source of armor and health regeneration.
* Between Poison Attack and
Viper Strike, Viper can keep Dragon Knight permanently slowed even in
Elder Dragon Form.
* Nethertoxin disables Bristleback's passive.
* Viper Strike and
Poison Attack slow down Bristleback's movement speed, making him unable to get out from Nethertoxin.
Additional:
* Viper Strike can disable
Bristleback and prevents
Warpath from building stacks. Besides losing his defensive passive, Bristleback also loses his ability to build up damage over lengthy battles.
* Viper can perpetually kite Bristleback with Poison Attack and
Viper Strike.
* Viper wins on the central line of Puck, because he has a huge damage from the Poison Attack ability, which Puck is not able to constantly avoid using
Phase Shift, which will give Viper an advantage in the possible damage inflicted on each other
* Puck takes more damage than it does due to the passive Corrosive Skin ability of the Viper, which makes it unprofitable for the Puck to fight against the Viper at an early stage of the game, when the Puck has a very small pool of health.
Additional:
* Viper wins on the central line of Puck, because he has a huge damage from the Poison Attack ability, which Puck is not able to constantly avoid using
Phase Shift, which will give Viper an advantage in the possible damage inflicted on each other
* Puck takes more damage than it does due to the passive Corrosive Skin ability of the Viper, which makes it unprofitable for the Puck to fight against the Viper at an early stage of the game, when the Puck has a very small pool of health
* Poison Attack and
Viper Strike allowing to kite and slow Earthshaker significally, putting
Blink Dagger on cooldown and preventing him from initiating or re-initiating.
* Nethertoxin breaks Aftershock. The silence from Level 25 talent also prevents Earthshaker from initiating or re-initiating.
Additional:
* Being a melee hero, Earthshaker's movement is liable to suppression by Poison Attack and
Viper Strike.
* Earthshaker's kit, with the exception of Enchant Totem, deals magic damage.
Corrosive Skin effectively blunts his killing potential with a standard Blink combo among other things.
* Viper Strike can disable
Aftershock, which removes the stun and bonus damage from
Enchant Totem and
Echo Slam.
* Viper's Nethertoxin disables
Cloak and Dagger, negating Riki's invisibility and much of his damage. It also makes him more vulnerable to magic damage, which does not go well with Riki's low health pool. With the talent applied, he can't even blink to safety or hide with Tricks of the Trade.
* Corrosive Skin makes it hard for Riki to chase Viper and attack him due to the attack speed slow.
* Viper Strike stays on Riki even after he goes invisible.
* Poison Attack makes it risky for Riki to get last hits and can make the laning phase difficult for him.
* Viper Strike is a strong and breaks Fury Swipes, undispellable slow, making it much easier to kite Ursa for everyone.
* His Poison Attack is very useful against Huskar, since he tends to stay at low health.
* Nethertoxin disables passive skills like Berserker's Blood.
* It is dangerous for Huskar to jump on Viper because Corrosive Skin and
Viper Strike with the slowdown of movement and attack speed which usually will be deadly for Huskar.
Additional:
* Viper Strike can disable
Berserker's Blood, which Huskar relies upon for attack speed and healing.
* The damage from Burning Spear and
Life Break is largely absorbed by
Corrosive Skin. It also will return some damage, making it risky to use Burning Spears in the laning stage.
* Because Huskar wants to be on low health for Berserker's Blood, he is particularly vulnerable to
Poison Attack.
* 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 Necrophos spells that deal magical damage, which is his only source of damage.
Additional:
* Viper Strike 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.
* 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.
* Nethertoxin disables Vengeance Aura.
* Vengeful Spirit has no mobility spells aside from Nether Swap, which Viper can take advantage of with his slows.
* Viper can easily bully Vengeful Spirit out of a lane with Poison Attack.
Additional:
* Viper Strike can disable the attack damage bonus from
Vengeance Aura and the components of
Nether Swap.
* Both Magic Missile and
Wave of Terror are counteracted by
Corrosive Skin, making Vengeful Spirit's fighting harder against Viper.
* Corrosive Skin severely reduces Zeus's damage output throughout the game.
* During the laning stage, Viper can abuse Zeus' reliance on spells by hugging the creep wave. Zeus will take constant damage over time from Corrosive Skin unless he drives Viper from the lane or returns to farming in his absence.
* Prior to buying Blink Dagger or
Force Staff, Zeus is fragile and possesses low mobility. Any of Viper's numerous slows can set up an easy kill.
Additional:
* Corrosive Skin counters Zeus in lane by canceling the effects of
Clarity as Zeus relies on Arc Lightning to farm and secure last hits.
* Corrosive Skin also increases Viper's magic resistance to shrug off Zeus's magical nukes.
* Nethertoxin breaks Static Field.
* Due to Zeus' poor mobility, Viper Strike will cripple Zeus and will allow Viper and his teammates to land a lot of attacks.
* Viper Strike prevents the lifesteal from Ransack.
* Meepo and his clones have a lack of magic resistance, so they're vulnerable to Poison Attack &
Viper Strike directed onto one clone.
* Poison Attack makes it hard for Void Spirit to lane against him.
* Corrosive Skin reduces the magical damage from Void Spirit's spells.
* Viper Strike prevents buildup of Fiery Soul stacks.
* Corrosive Skin provides magic resistance against Lina's spells. However, Lina can counter this with
Silver Edge, a common item on Lina.
* Poison Attack and
Viper Strike can burn away Lina's small health pool.
* Viper STrike cancels out
Kraken Shell and stops the hard dispel from passively activating, preventing Tidehunter from functioning as a frontline tank.
* Anchor Smash is mostly irrelevant against a ranged hero like Viper.
* Tidehunter relies on the threat of Ravage, which has an obscenely long cooldown. Viper can exploit the downtime with his short cooldowns.
* Nethertoxin disables Dawnbreaker's
Luminosity. Since she's a melee hero, she needs to close gap to attack and Nethertoxin will be bad for her since she cannot heal.
* Viper Strike and
Poison Attack will severely slow her down and combined with
Nethertoxin, it will be her death sentence (unless her Celestial Hammer or Solar Guardian are off cooldown). Besides that, chasing her down will be easy due to the slow.
* Viper's poison abilities can slow Bounty Hunter's movement speed and allows to chase him with True Sight items.
* Nethertoxin can break Jinada, and the silence from level 25 prevents Bounty Hunter from using all of his spells.
* Viper Strike can disable
Gravekeeper's Cloak, Visage's primary defense mechanism.
* Viper can ignore Grave Chill's attack speed slow with his magic damage output.
Additional:
* Since Visage is a slow hero, Viper can easily kite him with
Poison Attack and
Viper Strike while successfully chipping away at Gravekeeper's Cloak.
* Nethertoxin removes all layers of Gravekeeper's Cloak, leaving Visage exposed.
* Corrosive Skin makes Viper highly resistant to Soul Assumption.
* Heroes with break can disable Untouchable for a while: Doom and
Shadow Demon (via
Aghanim's Scepter),
Viper,
Shadow Shaman with Hex Breaks talent.
* Melee heroes with low mobility can be kited and killed by Viper: Treant Protector,
Kunkka,
Alchemist,
Troll Warlord,
Wraith King,
Tiny,
Sven.
* Hand of God has a long cooldown, so damage over time spells can be hazardous for Chen, forcing him to use it prematurely: Jakiro,
Venomancer,
Viper,
Dazzle,
Phoenix.
* Melee heroes with low mobility can be kited and killed by Viper: Treant Protector,
Kunkka,
Alchemist,
Troll Warlord,
Wraith King,
Tiny,
Sven.
* Heroes who rely on burst damage with magical damage will struggle to kill Primal Beast: Spirit Breaker,
Gyrocopter,
Leshrac
* Melee heroes with low mobility can be kited and killed by Viper: Treant Protector,
Kunkka,
Alchemist,
Troll Warlord,
Wraith King,
Tiny,
Sven.
* Heroes who rely on burst damage with magical damage will struggle to kill Primal Beast: Spirit Breaker,
Gyrocopter,
Leshrac
* Viper can bully Alchemist out of mid lane quite easily, forcing him to either retreat into jungle, or stay harassed in lane, and get very few last hits. Vipers break also completely disables
Greevil's greed which prevents Alchemist to earn his amazing amounts of money.
* Hard carries who just want to farm and be left alone will not appreciate Primal Beast, heroes such as Medusa,
Drow Ranger...
* 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.
* Heroes who do not have nor rely on passive abilities make Nethertoxin much less effective: Clinkz,
Pugna,
Nature's Prophet,
Dark Seer,
Lycan,
Tusk
* Sprout gets destroyed by Trample and Onslaught.
* Heroes that can drain mana negatively affect Viper's ability to use Poison Attack, Nethertoxin and Viper Strike: Lion,
Anti-Mage
* Viper's skill set makes him an effective early game ganker against Anti-Mage before he is sufficiently farmed.
* Viper's Corrosive Skin and low mana pool causes him to take little damage from Mana Void.
* Nethertoxin disables Mana Break and Counterspell, weakening both his offense and defense.
* Like above, supports with reliable stuns can be a massive problem and force Black King Bar in fights unideally, such as
Shadow Shaman,
Lion,
Nyx Assassin.
* Corrosive Skin minimizes the damage from
Impale and
Mind Flare, and anything else Nyx Assassin tries to throw at Viper.
* Nyx Assassin cannot survive several poison damage-over-time output from Poison Attack,
Nethertoxin,
Corrosive Skin and
Viper Strike, not even while he has
Spiked Carapace active. And to make things worse, Nyx Assassin is not a common
Silver Edge wielder to counter this problem at all.

Nethertoxin,
Corrosive Skin and
Viper Strike, not even while he has
Spiked Carapace active. And to make things worse, Nyx Assassin is not a common
Silver Edge wielder to counter this problem at all.
* Supports who can slow him to the point Trample does very little damage in the lane are also not fun: Lich,
Ogre Magi,
Winter Wyvern.
* Viper Strike breaks Multicast.
* Corrosive Skin minimizes the damage from Ignite and Fireblast.
* As Viper focuses on single-target damage, he has trouble fighting off Phantasm illusions.
* Reality Rift counteracts Viper's slows and reduces his already low durability against physical damage.
Additional:
* Viper has no response to the standard initiation combo of Reality Rift into
Chaos Bolt.
* Phantasm and
Chaos Strike can eliminate Viper almost instantly with it's damage output.
* Besides Nethertoxin, Viper has no other ways of dealing with Phantasm.
* Heroes with Attack speed decreasing skills: Jakiro,
Viper
Lich
* Illusion heroes will struggle against Primal Beast's area damage capability, such as Chaos Knight,
Naga Siren,
Terrorblade.
* Even though Luna has a hard time laning against Viper due to Nethertoxin being able to disable
Moon Glaives and
Lunar Blessing, Luna can take out Viper once she builds either
Black King Bar or
Silver Edge which will allow her to attack Viper freely.
* Eclipse can often finish off Viper from early-to-mid stages of the game before he can retaliate as
Corrosive Skin gives little magic resistance to him early on.
* Manta Style is an item that Luna commonly buys in most of the games, which lets her disjoint
Viper Strike. Additionally, illusions from Manta Style can make Viper waste time attacking them.

* Manta Style is an item that Luna commonly buys in most of the games, which lets her disjoint
Viper Strike. Additionally, illusions from Manta Style can make Viper waste time attacking them.
* 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.
* Almost all of Viper's damage revolves exclusively around single-target damage-over-time effects. Furthermore, without any hard disables, Terrorblade can almost always get a Sunder off.
* Viper has low mobility and Corrosive Skin doesn't protect against physical damage, which means that Terrorblade under Metamorphosis can quickly kill Viper.
Additional:
* Viper's damage over time and lack of disables makes him easy to Sunder.
* Viper's physical damage is mitigated by Terrorblade's high armor.
* Terrorblade under Metamorphosis can quickly kill Viper with heavy physical damage.
* 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.
* Pugna's Decrepify allows him to save allies from being ganked by Viper, since Viper mostly relies on direct attacks in order to deal damage.
* Nether Ward can discourage Viper from spamming his abilities.
* Viper's damage over time is not enough to kill Pugna as he will have more than enough time to save himself (or his allies) with Life Drain and Viper has no solutions to cancel it.
* Pugna has no passive abilities, which renders Nethertoxin nearly useless.
* 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.
* Glimpse can prevent Primal Beast from initiating for most of the game with Onslaught.
* While Static Storm is not much of a threat in terms of damage, it does prevent Primal Beast from casting any spells for a long period of time if also trapped in
Kinetic Field.
* Overall, Disruptor forces Primal Beast to buy a Black King Bar much earlier than he might like but becomes a major threat to Disruptor once he does.
* Corrosive Skin minimizes the damage Viper takes from all of Disruptor's skills.
* Primal Beast is disarmed during Trample so will be unable to destroy a Supernova no matter how close it is to him.
* The same ability can also be used to save allies with the help of an Aghanim's Scepter.
* Sun Ray will do thousands of damage to Primal Beast if surviving a full channel time due to his high health scaling for the ability.
* Icarus Dive is a fantastic way to escape Primal Beast after he has used Onslaught.
* Phoenix has a naturally very high health pool making it hard for Primal Beast to deal with him with his magical damage.
* Corrosive Skin gives Viper additional resistance to Phoenix's magical damage, and since they deal damage over time, Phoenix would be constantly afflicted by his passive's own debuff, making him not an ideal target for Phoenix's harassment. Phoenix's abilities also constantly drain its own health away, becoming more vulnerable to
Poison Attack.
* Viper's lack of escape and durability means he can be ran over in a laning stage by Spawn Spiderlings.
* Broodmother can bring Viper down quickly with Insatiable Hunger activated.
* 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.
* Borrowed Time allows him to both exit his stuns prematurely and turn Trample into healing for himself. His Aghanim Scepter only prevents the automation of the spell, Abaddon himself can still manually activate it.
* Aphotic Shield will immediately debuff any stuns Primal Beast has put on allies but won't stop him from being stunned if casted on Abaddon.
* Because Poison Attack has almost no cooldown, Aphotic Shield is ineffective as a hard dispel.
* Viper Strike can prevent
Borrowed Time from activating passively and block
Curse of Avernus.

To start select enemy heroes in the field above. It's intended to be used with multiple heroes. The more enemy heroes you provide the better results you will get.
This website was made to help you in pick stage of online game Dota 2. It calculates rating for each possible counterpicks based on tips from web-based database made up entirely of user contributions Dota 2 wiki.
You will get the list of recommended hero counters with a list of tips written by Dota 2 wiki contributors explaining why it's good against the particular hero. In comparison to other similar websites, which show only rating based on average hero win rate from dotabuff or similar service.
Take it with a bit of grain of salt, especially if the recommendation has a low rating (<= 1), some heroes
may win a lane in an early game but would lose in late game (and vice versa). That's why sometimes
you could hero names appearing as a counter and as being countered, as on image:
You can also add your own tips, update old data and fix mistakes by editing page on Dota 2 Wiki (it works like Wikipedia - anyone can contribute, you don't even need to register) these edits will appear on this website automatically (data is updated several times per week).
Right now there is no app/overlay that will detect picks automatically (like overwolf dota plus or become the gamer), instead, you can open web version in a steam in-game browser or use mobile version on your smartphone.

Shukuchi allows Weaver to have faster movement speed and can outrun Primal Beast in most instances, such as while he is trampling.
The Swarm can make him vulnerable to ranged attacks. Primal Beast also has an innately slow attack speed and will take a long time destroying the bugs.
Time Lapse allows Weaver to negate and heal burst damage, which Primal Beast is reliant on.
