Queen of Pain
* A good Nyx can reflect Queen of Pain's Sonic Wave with his 
Spiked Carapace, or even initiate a gank on her in 
Vendetta while she farms a creep wave with Scream of Pain.
* Her strength to intelligence ratio is bad enough that he should be able to kill her without even requiring a 
Dagon, provided he can get his full combo off.
Pugna
* 
Nether Blast's animation makes it easy to time Spiked Carapace for a stun.
* Pugna has the largest intelligence gain in the game, making him a prime target for Mana Burn.
* Pugna needs to channel 
Life Drain, making him easy to hit with Impale.
Additional:
* Due to Pugna's incredible intelligence growth and terrible strength growth, Nyx should always be able to take you out with his combo, with or without an added Dagon. 
Mind Flare will deal a large amount of damage in particular, especially in the late game.
* Spiked Carapace is also a great tool versus Pugna. A good player will wait for you in Vendetta until you farm a creep wave with Nether Blast and reflect it back at you as their initiation and setup for 
Impale.
Queen of Pain
* Aggressively blinking is not going to end well against Luna, because Queen of Pain will be an easy target for 
Lucent Beam & 
Eclipse.
* Queen of Pain's HP is abysmal, so Luna can quickly kill Queen of Pain as soon as she initiates with Blink.
Additional:
* Aggressively blinking is not going to end well against Luna, because Queen of Pain will be an easy target for Lucent Beam & Eclipse.
* Queen of Pain's HP is abysmal, so Luna can quickly kill Queen of Pain as soon as she initiates with Blink.
Pugna
* Luna can deal constant damage to Pugna through the low-cooldown Lucent Beam and her right clicks.
* Life Drain will be always canceled by Lucent Beam if Pugna does not have 
Black King Bar.
* 
Decrepify can be suicide against Luna due to Lucent Beam and Eclipse.
* 
Nether Ward is rather weak against Luna because unlike other heroes who rely on magical damage to damage or kill enemies, yet their ablities have very high mana costs, Luna does not have abilities that cost a lot of mana and Luna mostly uses her abilities to initiate a teamfight or to finish off fleeing enemy heroes.
* Luna is a common Black King Bar carrier, which allows her to protect herself against Pugna's only-magical damage output.
Additional:
* Luna can deal constant damage to Pugna through the low-cooldown Lucent Beam and her right clicks.
* Life Drain will be always canceled by Lucent Beam if Pugna does not have Black King Bar.

* Luna is a common Black King Bar carrier, which allows her to protect herself against Pugna's only-magical damage output.
Queen of Pain
* Because Queen of Pain's spells cost a decent amount of mana, Anti-Mage can easily use 
Mana Void if she spams her spells recklessly.
* Anti-Mage has similar mobility through 
Blink, which can allow him to catch up to or flee from her.
* 
Counterspell will reduce the damage done by Shadow Strike and Scream of Pain. Additionally, its active component also reflects Shadow Strike back at her if Anti-Mage times it right.
Pugna
* Pugna only deals magical damage, which Anti-Mage is exceptionally resistant due to Counterspell.
* Anti-Mage can dispel Decrepify with 
Manta Style.
* Pugna has a very large mana pool. This allows Anti-Mage to constantly deal bonus damage to Pugna with Mana Break and devastate Pugna's entire team with Mana Void.
Additional:
* Since Pugna relies on his teammates for protection, it is fairly common for Anti-Mage to get multiple kills with a single use of his Mana Void on Pugna if he's missing a considerable portion of his mana.
* Pugna's massive mana pool will result in Anti-Mage's 
Mana Break almost always dealing the bonus damage from the mana burn.
* Counterspell negates a large amount of Pugna's damage, as most of Pugna's damage comes from his spells.
* Blink can be used to get out of a bad situation, and Pugna has no way to prevent him from casting it.
Queen of Pain
* Chain of Earthbinds prevents her from using 
Blink, allowing Meepo to quickly kill her with Poof and attacks.
* Meepo tends to buy items with attributes, mitigating Queen of Pain's magical burst.
Additional:
* Meepo is the hard counter for Queen of Pain - chaining 
Earthbinds prevents her from using Blink for a long time, and without any other escape options, Queen of Pain cannot survive several 
Poofs and attacks.
* Meepo tends to build items with attributes, mitigating Queen of Pain's magical burst.
Pugna
* 
Pugna's Nether Ward doesn't really hurt Meepo since he usually buys attribute items to tank up and can be killed very quickly by 4 clones. Decrepify can amplify Poof's damage should Pugna use it to avoid Meepo's right clicking.
Queen of Pain
* 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.
Pugna
* 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.
Pugna
* All of Pugna's damage is magical, which can get blocked by 
Fate's Edict's 100% magic resistance.
* Oracle has two abilities that apply a dispel, which can easily remove Decrepify on his ally or Oracle.
Queen of Pain
* Shadow Shaman has many disables to lock down Queen of Pain, preventing her from Blinking away, even through 
Linken's Sphere or her spell block talent.
* 
Mass Serpent Ward can tear through Queen of Pain's low health pool once she's locked down by 
Hex & 
Shackles.
Queen of Pain
* Blood Rite prevents Queen of Pain from escaping with Blink.
* Blink will trigger the extra damage from Rupture.
Additional:
* 
Blood Rite silences her, preventing her from initiating or escaping.
* With 
Thirst, even if she Blinks away, Bloodseeker can catch right up to her.
* 
Rupture will heavily damage Queen of Pain if she tries to Blink away.
* She is, however, one of the few heroes who can avoid the damage from Rupture if she successfully blink-walks.
Pugna
* Earth Spirit does not fly a small distance on 
Rolling Boulder using 
Stone Remnant, which will be a big problem for Life Drain, since Pugna will stop receiving health from breaking the distance of the ability, which will give the Earth Spirit team a chance to kill Pugna, by the way, this also works well with 
Boulder Smash, which pushes the enemy and can annoy the distance
* Earth Spirit has excellent control with a small recharge on Rolling Boulder and 
Geomagnetic Grip, which can knock down Pugna`s Life Drain, as well as completely turn him off in a fight, because he is very dependent on his abilities
* Magic damage from Earth Spirit's abilities can be disastrous for Decrepify, as it will kill him very quickly, and if Earth Spirit collects 
Ethereal Blade in such a game, it can easily destroy Pugna in one Rolling Boulder hit
* Earth Spirit also turns out to be a strong decision against Nether Ward, because he experiences it with his large amount of health, and if he collects 
Heart of Tarrasque(and 
Bracerin early game)in such a game, he may not feel it at all and calmly control Pugna with his abilities

Pugna
* If Ursa uses 
Enrage, Pugna's Life Drain is next to worthless against him, due to Ursa taking 80% less damage, therefor Pugna heals by only 20% of the damage that the spell normally deals.
* It also dispels Decrepify, Even if you wait until he casted it, he can still dispel it with Shard upgraded 
Earthshock
* Ursa also commonly builds 
Skull Basher. With his high Attack Speed from 
Overpower. he can easily cancel Life Drain
* If Decrepify is defensivly casted, Ursa can still cast Earthshock both to slow you, and to deal amplified magic damage. He also commonly builds a 
Nullifier
* If Ursa jumps on you with a 
Blink Dagger he can easily wipe you out with Overpower.
* Ursa's Overpower can destroy a full health Nether Ward and still have a few swipes leftover, Also Ursa's low mana spells means he takes negligible damage from the Nether ward anyway.
* Ursa is also a common 
Diffusal Blade carrier, using it to both amplify his damage, but as his primary way to catch fleeing heroes
* Pugna is also the primary target of Ursa, due to him being both quite squishy, and a serious threat to his team, Ursa prioritizes the weakest link as 
Fury Swipes stacking damage will quickly demolish them, allowing Ursa to safely switch heroes
Queen of Pain
* A good Centaur can catch Queen of Pain with a Blink Dagger and 
Hoof Stomp.
* 
Retaliate with 
Blade Mail reflects all of Queen of Pain's damage, especially Sonic Wave.
* 
Stampede grants a movement speed bonus, which can prevent Queen of Pain from initiating.
* 
Double Edge can shred her low health pool if she's not careful.
Queen of Pain
* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, 
Storm Spirit, 
Ember Spirit, 
Lycan, 
Bloodseeker, Anti-Mage, 
Timbersaw.
Additional:
* Puck will make a game of dodging as many Shadow Strikes as he can with 
Phase Shift. If he's a good player, he will also dodge Sonic Wave. If he's a great player, he will also dodge Scream of Pain, and it's all thanks to this single spell.
* Puck also has a silence in 
Waning Rift to prevent Queen of Pain from blinking away.
* Puck can provide vision to hunt her down if she blinks into the trees with 
Illusory Orb.
* If Queen of Pain is under the effect of 
Dream Coil, she will be unable to blink out.
Pugna
* Puck can dodge Nether Blast and Life Drain with his Phase Shift, easily avoiding Pugna's strong burst magic damage.
* Waning Rift's silence allows Puck and its teammates to easily deal with Pugna, which cannot do the same to it, because with Puck it will be easy to avoid such an attack from the Decrepify.
* The Puck's combo: Waning Rift + Illusory Orb + Dream Coil doesn't have a huge amount of damage to feel the damage of the Pugna from Nether Ward, however, it may be quite enough to kill the Pugna solo at an early stage of the game with 
Witch Blade
Additional:
* Puck easily dodges the Nether Blast and the Pugna Life Drain with his Phase Shift, which is why he can easily avoid his strong magic damage
* The Puck's silence from the Waning Rift ability allows her team to easily cope with the Pugna, which cannot be said about the Pugna, because with the Puck it will be easy to avoid such an attack from the Decrepify
* The Puck's combo: Waning Rift + Illusory Orb + Dream Coil doesn't have a huge amount of damage to feel the damage of the Pugna from Nether Ward, however, it may be quite enough to kill the Pugna solo at an early stage of the game with Witch Blade
Queen of Pain
* Once you farm up an 
Orchid Malevolence or a 
Scythe of Vyse, you're suddenly a lot more fearsome to elusive heroes like Storm Spirit or even that pesky 
Puck.
Pugna
* Both Jakiro's Ice Path and Liquid Frost can be used to cancel Life Drain from either Jakiro or an ally.
* Decrepify only makes Pugna even more vulnerable to Jakiro's magical damage, And it has no adverse effects on Jakiro himself.
* 
Aghanim's Scepter upgraded 
Macropyre can deal pure damage-over-time and pierce debuff immunity, which can discourage Pugna from even trying to use Life Drain.
* Bear in mind, however, that Nether Ward can do some considerable damage to Jakiro due to high mana costs on his abilities.
Queen of Pain
* Ghostship helps your team soak up damage from 
Sonic Wave and 
Scream of Pain.
* Queen of Pain can't escape easily from X Marks the Spot - Torrent combo.
* Outlanes Queen of Pain on the midline, due to the fact that Queen of Pain has a small reserve of health at the beginning of the game, and she suffers very much from 
Tidebringer, which is why she is forced to either spend money on 
Tango, or skip creeps and run for bounty runes, and Kunkka at this time will gain an advantage in level and gold.

* Kunkka will catch her in 
X Marks the Spot and allow his team to kill her for stun from 
Torrent, because Queen of Pain has no way to avoid the cross X Marks the Spot before buying Black King Bar.
Pugna
* 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.
Queen of Pain
* All of Queen of Pain's abilities are worthy choices for Rubick to 
Spell Steal. In addition, he can cast her abilities from further distances than her thanks to 
Arcane Supremacy's increased cast range and spell amplification.
Pugna
* Life Drain does not instantly kill the illusions from 
Phantasm
* 
Chaos Bolt and 
Reality Rift can easily interrupt the channeling from Life Drain.
* Reality Rift makes it harder for Pugna to keep his distance between Chaos Knight.
* Nether Ward barely deals any significant damage on Chaos Knight as Chaos Knight's abilities do not cost a lot of mana
* The overwhelming damage of Chaos Knight and his illusions will do a quick work on Pugna's poor HP pool, or safely remove the Nether Ward from the battlefield.
Pugna
* Phantom Lancer creates way too many illusions for Pugna's Life Drain to destroy, overwhelming him easily.
* 
Doppelganger can dodge Nether Blast or dispel Decrepify.
* Diffusal Blade is a common item for Phantom Lancer to burn Pugna's large mana pool and deals a large amount of damage in the process.
Additional:
* Though Life Drain instantly destroys illusions, Phantom Lancer creates way too many for Pugna to handle.
* A good Phantom Lancer will also dodge your Nether Blast with Doppelganger.
* Phantom Lancer is the most natural Diffusal Blade carrier to burn Pugna's very large pool of mana away and deal a large amount of damage in the process.
Pugna
* Fragile heroes: Bounty Hunter has decent nuking capabilities with Shiruken Toss and Jinada thus making fragile heroes easy picks for ganking. Few examples of such heroes are:
Crystal Maiden, Pugna, 
Skywrath Mage, 
Io, 
Witch Doctor, etc.
Pugna
* Heroes with channeled abilities can be interrupted by a long-range Fissure: Crystal Maiden, Witch Doctor, 
Bane, Pugna, 
Pudge.
Queen of Pain
* Heroes with mobility spells like Queen of Pain, Anti-Mage, Phantom Assassin, 
Riki, Puck, and 
Spirit Breaker that are cancelled by Frostbite can suffer greatly from the presence of Crystal Maiden. It is absolutely critical, however, to have followup from teammates, as all of the above heroes can make quick work of the squishy Crystal Maiden after they are released from her grip.
Queen of Pain
* Heroes who recklessly jump on Pudge with their gap-closing abilities will be easy targets for Pudge's Meat Hook and Dismember Combo: Phantom Assassin, 
Faceless Void, Queen of Pain etc.
Pugna
* Heroes who build a Black King Bar (or have any sources of spell immunity) to channel abilities/items can still get interrupted by Dismember: 
Enigma, 
Juggernaut, Phantom Assassin, Pugna, 
Elder Titan.
Queen of Pain
* Heroes with a high degree of mobility and invisibility are hard to catch with Meat Hook: Ember Spirit, Riki, 
Clinkz, Queen of Pain.
Queen of Pain
* Heroes who rely on high mobility are especially vulnerable to Primal Roar: Storm Spirit, Ember Spirit, Queen of Pain.
Queen of Pain
* Night Stalker has a huge, almost instant silence through 
Crippling Fear. The main problem is that he can get it off while Queen of Pain barely has any vision of him if he creeps up to her during 
Dark Ascension. She'll have to play very carefully before she gets a Black King Bar or a 
Eul's Scepter of Divinity.
Pugna
* Heroes that can punish aggressive heroes, such as: 
Leshrac, 
Shadow Demon, Pugna, 
Death Prophet.
Queen of Pain
* Lina has a very long range of attack, which completely overlaps the range of Queen of Pain's abilities and attacks, which is why even a single 
Shadow Strike roll can become deplorable, since Lina will shoot Queen of Pain from a long distance before and after the Shadow Strike roll. And with the help of the abilities of 
Light Strike Array and 
Laguna Blade, Lina can even kill Queen of Pain because of her small health reserve if she is exposed to a blow
Additional:

And with the help of Light Strike Array and Laguna Blade, Lina can even kill Queen of Pain because of her small health reserve if she is exposed to a blow.
Pugna
* Nether Ward will be problematic for heavy nukers and spammers like Skywrath Mage, 
Lina, 
Lion and 
Invoker, but Pugna must not use Decrepify defensively against them as he will be helping them out more than anything.
Queen of Pain
* Smoke Cloud prevents Queen of Pain from using any of her offensive and defensive spells, rendering her unable to effectively react to Riki's attack.
* It's easy to dodge Sonic Wave by using Blink Strike & Tricks of the Trade.
Pugna
* Heroes who are reliant on physical damage will be nullified by Decrepify: Riki, 
Wraith King, Juggernaut.
Pugna
* Sniper's huge range makes him an unviable target to use Life Drain on, forcing Pugna to risk playing out of position to use it on Sniper.
* Sniper's 
Shrapnel can be used to provide vision on Nether Ward, and his range allows him to easily take it out.
* A clumsy Pugna may accidentally boost Sniper's Shrapnel and 
Assassinate damages if he recklessly uses Decrepify on himself or his allies.
Queen of Pain
* Heroes with high mobility can approach Sniper: Anti-Mage, 
Earth Spirit, Io, 
Nature's Prophet, 
Pangolier, Puck, Queen of Pain and most notably Riki.
Queen of Pain
* Queen of Pain usually outlanes Invoker, giving her team a significant early game advantage while Invoker is still farming.
* Blink allows Queen of Pain to escape from Invoker's combo if he doesn't have disables.
Pugna
* Nether Ward on its own can greatly hinder Invoker from casting many of his abilities, at least until he gets a significant amount of HP or is under the protection of spell immunity from Black King Bar
* Life Drain provides True sight, revealing Invoker through Ghost Walk, and forcing him or his allies to use an ability or item to interrupt its channeling
* Outside of Nether Ward's range, Invoker shall have the advantage, as Invoker has Tornado to purge Pugna's Decrepify when it is used defensively, Tornado or Cold Snap to prevent Pugna from channeling Life Drain
* A poorly used Decrepify on Pugna's allies means Invoker's abilities can be used to deal more damage to them.
Additional:
* Because Invoker relies on casting a large amount of spells to contribute to fights, Nether Ward can force him to not cast anything at all or take a large amount of damage to cast spells.
Queen of Pain
* All of Queen of Pain's abilities are active, making Demonic Purge break from Aghanim's Scepter useless.
* However, Demonic Purge can help his allies kill a squishy Queen of Pain.
* Blink allows Queen of Pain to escape from Shadow Demon's abilities if he doesn't have disables.
* An attempt to save an ally using Disruption can easily become a perfect setup for a Sonic Wave for the enemy.
Pugna
* All of Pugna's abilities are active, making Demonic Purge break from Aghanim's Scepter useless.
* Nether Ward punishes Shadow Demon's constant mana usage from spamming spells, especially Shadow Poison.
* An attempt to save an ally using Disruption can easily become a perfect setup for a Nether Blast for the enemy.
* Life Drain can be used to heal Pugna or an ally to save them from Shadow Demon's abilities.
* However, it can be cancelled by Disruption unless Pugna buys defensive items.
Queen of Pain
* Heroes that can jump on her: 
Slark, Queen of Pain, Anti-Mage
Additional:
* Queen of Pain often relies more on abilities than right-clicks, making 
Untouchable nearly useless against her.
* Enchantress also has a lower health pool than Queen of Pain, making her vulnerable to Queen of Pain's damage burst.
Pugna
* Amazingly, Enchantress has even lower health than Pugna. Though she does pack quite a punch through 
Impetus, she can't use it if she is under Decrepify.
* Pugna's Magical DPS is way greater than the heal from 
Nature's Attendants, which will also harm her quite a bit if she's next to Nether Ward.
Queen of Pain
* Weak damage but high tick rate or persist in a long time: Slark, 
Gyrocopter, Queen of Pain, 
Shadow Shaman (Shackles), 
Jakiro, Pugna, 
Doom
* Heroes that can quickly deal damage to her, regardless of how weak they are, can easily break through her Refraction:
* Multiple attackers thanks to summoned units or clones: 
Meepo, Witch Doctor, Lycan, Enigma, Shadow Shaman
* Multiple attackers thanks to illusions: 
Phantom Lancer, 
Chaos Knight, 
Naga Siren (bonus for her 
Ensnare). Also despite the visual effects, Templar Assassin does not spill damage against illusions or buildings, so she is not a really good hero to clean up illusions.
* Weak damage but high tick rate or persist in a long time: Slark, Gyrocopter, Queen of Pain, Shadow Shaman (Shackles), Jakiro, Pugna, Doom
Pugna
* Pugna's Decrepify can render Templar Assassin's physical attacks useless.
* Pugna can also cast Life Drain on Templar Assassin, burning her Refraction instances.
* On the other hand, Pugna generally has low health and armor. Use this to your advantage.
Queen of Pain
* Timbersaw has a difficult time against magical and pure damage: Lina, Leshrac, 
Enchantress, Queen of Pain
Pugna
* Nether Ward can punish Timbersaw, as Timbersaw is a spell-caster with low cooldowns. Furthermore, Timbersaw usually appears in the midst of battle, placing himself in range of Nether Ward's Mana Flares.
* Timbersaw has no stuns or silences to stop Life Drain. Since all of Pugna's Spells are magical, the damage can be devastating to Timbersaw.
* Decrepify can further increase all the magical damage done to Timbersaw, bypassing the enhanced physical resistance he can get from 
Reactive Armor.
Additional:
* Nether Ward can punish Timbersaw, as Timbersaw is a spell-caster with low cooldowns. Furthermore, Timbersaw usually appears in the midst of battle, placing himself in range of Nether Ward's Mana Flares.
* Timbersaw has no stuns or silences to stop Life Drain. Since all of Pugna's Spells are magical, the damage can be devastating to Timbersaw, especially when combined with Decrepify.
Queen of Pain
* Heroes with high burst damage: Lina, Lion, 
Luna, 
Nyx Assassin, Queen of Pain.
Pugna
* Decrepify prevents Shadow Fiend from attacking for its duration, potentially preventing him from getting a kill.
* Nether Ward can do heavy damage to Shadow Fiend if he tries to cast his 
Requiem of Souls and his 
Shadowraze.
Additional:
* Decrepify prevents Shadow Fiend from attacking for its duration, potentially preventing him from getting a kill.
* Nether Ward can do heavy damage to Shadow Fiend if he tries to cast his Requiem of Souls or spam Shadowraze.
Queen of Pain
* Heroes with teleports to escape Solar Blind and Will-O-Wisp: Phantom Assassin, Puck, Queen of Pain, Storm Spirit
Pugna
* Pugna easily copes on the line with the Keeper of the Light push with his Nether Blast, and in addition to Nether Ward, the Keeper of the Light is not able to throw 
Illuminate on creeps for a long time, so Pugna earns more gold and a level on the line
Additional:
* Pugna easily copes on the line with the Keeper of the Light push with his Nether Blast, and in addition to Nether Ward, the Keeper of the Light is not able to throw Illuminate on creeps for a long time, so Pugna earns more gold and a level on the line
Queen of Pain
* Heroes with escaping and disjointing abilities can be good against Juggernaut:Anti-Mage Riki, Queen of Pain, Puck, Storm Spirit, Ember Spirit, Slark etc.
Pugna
* Decrepify prevents 
Omnislash damage, until Juggernaut gets a Nullifier.
* Without a disable, Pugna's high movement speed makes it harder to chase him with 
Blade Fury.
* Juggernaut has low mana and his skills cost large amount of mana. Nether Ward will hurt him more and even worse, the damage from the ward is inflicted before the Spell immunity provided by Blade Fury.
Additional:
* Decrepify is the perfect tool against Omnislash until he gets a Nullifier, and even then he will probably waste a couple of slashes before he uses it.
* Without an extra disable, Pugna's high movement speed makes it impossible to chase him with Blade Fury.
* Unlike some other carries like Slark or Phantom Assassin, Juggernaut's spells cost a hefty amount of mana and he will seriously get hurt by Nether Ward. Don't forget the damage from the ward is inflicted before the spell immunity is provided by Blade Fury.
Queen of Pain
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, Earth Spirit, Faceless Void, 
Magnus, 
Mirana, 
Monkey King, 
Morphling, Pangolier, Phantom Assassin, 
Phoenix, Puck, Queen of Pain, Riki, 
Sand King, Spirit Breaker, Timbersaw, 
Tusk.
Queen of Pain
* Both Scream of Pain and Sonic Wave should hit Slark during his 
Shadow Dance.
Pugna
* Nether Blast will still hit Slark even if he is hidden during Shadow Dance.
* Even though Pugna can rarely target Slark directly with Decrepify, he can still use it defensively on an ally to prevent Slark from getting stacks.
* Despite being somewhat easy to break with Pounce, Pugna can damage Slark and provide vision over him with Life Drain.
Queen of Pain
* Heroes with mobility spells (such as Queen of Pain's Blink and 
Clockwerk with 
Hookshot) can easily avoid 
Lil' Shredder and 
Mortimer Kisses.
* Heroes with high movement speeds like Pugna and Meepo can run around, to, or away from Snapfire during Mortimer Kisses and dodge the projectiles easily due to their slow speed.
Pugna
* Heroes with high movement speeds like Pugna and Meepo can run around, to, or away from Snapfire during Mortimer Kisses and dodge the projectiles easily due to their slow speed.
* Heroes with mobility spells (such as Queen of Pain's Blink and Clockwerk with Hookshot) can easily avoid Lil' Shredder and Mortimer Kisses.
* Heroes with high movement speeds like Pugna and Meepo can run around, to, or away from Snapfire during Mortimer Kisses and dodge the projectiles easily due to their slow speed.
Queen of Pain
* 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

Rain of Destiny from

Black Hole and 
Midnight Pulse,

Pugna
* Heroes with magical or pure damage output will not have any problems against Atrophy Aura at all: Luna, Lina, Jakiro, Pugna, Bane, 
Snapfire, Muerta, Nyx Assassin, Enigma, 
Tinker, Witch Doctor, Zeus, Crystal Maiden.
Queen of Pain
* Queen of Pain, for the most part, almost exclusively deals magical damage, ignoring Windranger's evasion from 
Windrun.
* Queen of Pain is also a common wielder of Orchid Malevolence, preventing Windranger from using her abilities for a while.
* Blink, when used correctly, allows Queen of Pain to dodge 
Powershot and 
Shackleshot.
Queen of Pain
* Queen of Pain can be an effective tool against Batrider in the game and on the line. She has long-range abilities such as Scream of Pain or Sonic Wave and a long-range type of attack, which is why she can keep Batrider at a distance all the time, and prevent him from attacking with Flaming Lasso or Firefly. Queen of Pain has an effective high-deceleration ability against Batrider - Shadow Strike, which is why he cannot quickly set fire to all enemies under Firefly and fly between all Queen of Pain allies. In addition, Queen of Pain has a wonderful escape in stock - Blink, which can save her at any moment in which batrider decides to attack

Pugna
* Nether Blast can deal high damage to Chen and clear waves of his creeps.
* Decrepify can be used to waste the duration of 
Penitence.
* Nether Ward can discourage Chen from using Penitence, 
Holy Persuasion and 
Hand of God due to their fairly high mana costs.
* Life Drain can often kill Chen or any of his allies before he can save them with Hand of God thanks to it's high damage and low cooldown.
Pugna
* Pugna can save allies with both healing or by making them ethereal but needs to be careful of Sven's Aghanim's Scepter purge.
Queen of Pain
* Blink allows Queen of Pain to avoid ganks and keep her distance, preventing Monkey King from building up Jingu Mastery.
* Scream of Pain and Sonic Wave will hit Monkey King when he is disguised, or on a tree.
* The large AoE and low cooldown also helps Queen of Pain hit the real Monkey King inside of Wukong's Command.
Pugna
* Pugna can turn out to be an effective hero against Dazzle due to the fact that he does not allow him to extend his 
Poison Touch with his Decrepify, which is why Dazzle cannot keep the enemy under prolonged deceleration.
* Pugna has a very strong ability against casters with a small health reserve - Nether Ward, which is why heroes like Dazzle will not be able to constantly throw their Poison Touch 
Bad Juju and 
Shadow Wave at enemies under the action of Nether Ward or will be forced to take a lot of damage

Pugna
* Nether Blast, Decrepify and Life Drain deal high magical damage and bypasses Bulwark.
* Nether Ward reduces the amount of abilities Mars can use during fights and forces Mars to be careful about the heavy mana cost of Arena Of Blood.
* Pugna is one of few heroes that can contest Mars' ability to push and defend towers early on.
Queen of Pain
* Blink makes it hard for Gyrocopter to pin down Queen of Pain.
* Sonic Wave is very effective at ganking Gyrocopter in the early game.
Queen of Pain
* Blink can instantly break Static Link, making it useless against her.
* Queen of Pain doesn't fully rely on her physical attack damage, so she can still fight after being hit with Static Link.
Pugna
* Troll Warlord can't switch targets at will, in order to build 
Fervor stacks, which makes it easy to use Decrepify in order to save allies
* During 
Battle Trance, Pugna can easily use Nether Blast, Decrepify and Life Drain on him
Pugna
* Nether Ward punishes Leshrac's constant mana usage from spamming spells.
* Leshrac needs to be in the thick of the fight to deal damage, and so cannot escape from Nether Blast nor Life Drain easily.
Additional:
* Leshrac needs to be close to target in order to do damage, Pugna can outrun Leshrac with ease due to his superior movement speed.
* 
Split Earth can also be hard to land on Pugna for the same reason.
* Leshrac uses huge amounts of mana to do damage, Nether Ward forces him to either not contribute in a fight or kill himself in the process.
Pugna
* Nether Ward discourages Tinker from using abilities and items due to its high damage against heavy mana usage.
Pugna
* 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.
Queen of Pain
* Husker is the kind of hero that likes to remain at low health, which is perfect for Queen of Pain to burst with Sonic Wave.
* She should be able to Blink away after he jumps on her with 
Life Break.
Pugna
* Even though Pugna's low HP means that he can be quickly burst down, his Nether Ward heavily punishes casters whose spells cost a lot of mana, like Zeus. Casting 4 of his active spells, including Nimbus, close to an enhanced level 4 Nether Ward, can make the ward deal up to 1750 magical damage.
* Decrepify can further increase the damage dealt by Nether Ward upon Zeus. However, if used on Pugna himself or on one of his allies, it will amplify the damage done by Zeus' abilities.
Pugna
* Nether Blast is one of the best tower pushing abilities in the game, with a low cooldown. A competent Pugna will (at the very least) destroy tier 2 towers and make space for his team before Spectre can finally come online.
* Spectre's spells, while not spammable, have a fairly high mana cost, so Nether Ward can be fairly damaging to Spectre early game. The mana degen will also dampen Spectre's early game power significantly.
* Once Pugna gets Aghanim's Scepter, he can spam Life Drain on any illusion Spectre summons, whether it'd be from 
Haunt, Manta Style, or some other means.
* In addition, Pugna can disable Spectre's 
Desolate ability (although its damage is pure, it requires physical attacks) with his Decrepify ability, leaving Spectre only with 
Spectral Dagger.
Pugna
* Enigma's abilities have a huge mana cost, meaning that Nether Ward will deal a lot of damage to Enigma.
* Pugna can heal allies trapped inside Black Hole thanks to Life Drain, Pugna can also damage multiple of Enigma's allies around him with Life Drain when he casts it on Aghanim's Shard upgraded Nether Ward during teamfight.
* Nether Blast can easily kill Eidolons, especially when Enigma is pushing.
* Even though Pugna cannot cancel Black Hole on his own, smart Pugna can buy Orchid Malevolence to stop Enigma from channeling Black Hole and make him more vulnerable to counter-attacks with Decrepify and Life Drain.
Additional:
* Enigma's abilities have a huge mana cost, meaning that Nether Ward will deal a lot of damage to Enigma.
* Pugna can heal allies trapped inside Black Hole thanks to Life Drain.
* Nether Blast can easily kill Eidolons, especially when Enigma is pushing.
Queen of Pain
* Queen of Pain can Blink to both escape and initiate onto Void Spirit.
* She is also a very common Orchid Malevolence carrier, which can prevent Void Spirit from contributing much in fights.
Pugna
* Cold Embrace is a death sentence against Pugna, since its the perfect setup for all his abilities, especially Life Drain.
* Decrepify can be cast to save the ally under Winter's Curse effect, wasting most of its duration.
* Winter Wyvern's abilities require a lot of mana, allowing Nether Ward to deal lots of damage.
Queen of Pain
* Queen of Pain can easily escape Chain Frost thanks to Blink.
* His low survivability makes an easy kill for Shadow Strike, Scream of Pain & Sonic Wave.
Queen of Pain
* Heroes that have superior mobility that can easily catch up with Mirana even after she used Leap to escape: Anti-Mage, Queen of Pain, Storm Spirit, Riki.
Pugna
* Heroes that commonly attack ethereal units will not have any problems against Muerta's Pierce The Veil: Tinker, Jakiro, Lina, Luna, Pugna or 
Ogre Magi, Enigma, Batrider, 
Techies, Broodmother, Dawnbreaker, Shadow Shaman, Bane, Tinker, Venomancer, 
Arc Warden.
Pugna
* As Terrorblade's damage output comes mainly from direct attacks, he will struggle greatly against heroes who have abilities that give evasion, trigger on attack or which can disarm an enemy hero: 
Centaur Warrunner, 
Hoodwink, 
Huskar, Invoker, Leshrac with 
Nihilism from Aghanim's Scepter, 
Lifestealer with Aghanim's Scepter upgraded 
Infest, Pangolier, Phantom Assassin, Pugna, Techies, 
Windranger etc.
Queen of Pain
* Heroes with mobility spells can quickly escape from Stroke of Fate or break out of Soulbind: Anti-Mage, Queen of Pain, Morphling, Storm Spirit
Queen of Pain
* Queen of Pain can be a good hero for dealing with Ember Spirit with Orchid Malevolence, her pure damage nuke in Sonic Wave and a slow in Shadow Strike. However, Queen of Pain can be punished by Ember Spirit, as his Searing Chains prevents her from getting Blink off.
Pugna
* 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.
Pugna
* Heroes that can apply early pressure before Phantom Assassin has farm are massive threats: Axe, 
Viper, Meepo, Jakiro, Pugna, Slark, Venomancer etc.
Pugna
* Any hero that can outrange Plague Ward can neutralize them without putting themselves at risk of receiving Poison Sting: Arc Warden, 
Chen, Clinkz, 
Drow Ranger, Lina, Mirana, Nature's Prophet, Pugna and 
Sniper.
* Special mention to heroes that outrange Plague Ward after obtaining talents that increase attack range.
Pugna
* Pugna's Decrepify makes sure that either Alchemist is unable to hit anyone while also being slowed and susceptible to magical damage, or can protect an ally from physical attacks. Besides, Pugna can push early on, when Alchemist is not strong enough to repel it, so by the time Alchemist comes online, he might be forced to sit in base.
Queen of Pain
* Dark Seer's only disable is Vacuum. Though he starts off with high armor and health, he'll eventually have a hard time dealing with high mobility heroes such as 
Weaver or Queen of Pain.
Queen of Pain
* Heroes with mobility/escape mechanisms to dodge Ancient Apparition abilites, or to easily jump on him: Riki, Queen of Pain, Phantom Assassin, Windranger, 
Bounty Hunter, Spirit Breaker, 
Night Stalker, Storm Spirit, Juggernaut, etc.
Pugna
* Heroes who are reliant on physical damage will be nullified by Decrepify: Riki, Wraith King, Juggernaut.
Queen of Pain
* Heroes who have a high mobility (Queen of Pain, Storm Spirit, Slark, etc.).
Pugna
* Pugna's Decrepify prevents the target from taking physical damage or doing damage, which poses a huge problem for Lycan, as he mainly deals physical damage.
Pugna
* Any heroes with high intelligence, such as Invoker and Pugna.
Queen of Pain
* Blinking heroes like Anti-Mage or Queen of Pain can often chase down an injured Brewmaster after his ultimate expires.
Pugna
* Pugna: Decrepify prevent the Spirit bear from attacking or protect allies from it.
Queen of Pain
* Heroes with damage over time abilities can quickly eat through Gravekeeper's Cloak charges like Huskar, Jakiro and Queen of Pain.
Queen of Pain
* Heroes that have escape abilities (such as Queen of Pain, Storm Spirit or Timbersaw) can be either nullified by Reaper's Scythe or a complimentary item for Necrophos (like 
Rod of Atos or Scythe of Vyse). If Necrophos is quick enough and enters range, they can quickly, if not instantly, die if they are not quick enough.
Pugna
* Nether Ward causes Death Pulse to actually damage Necrophos rather than heal him. Meanwhile, Reaper Scythe's gigantic mana cost while Necrophos is near the Nether Ward can often instantly kill him.
* Nether Blast and Life Drain both make quick work of Necrophos's small healthpool, especially during Ghost Shroud. The latter also makes him an unappealing target for Reaper's Scythe, and can often force Necrophos to use it defensively as he has no other means of interrupting his channeling.
Queen of Pain
* Heroes reliant on abilities to output damage or escape can be shut down by Gust: Queen of Pain.
Queen of Pain
* Often you can burst Drow Ranger down before she has a chance to try and 
Gust you away. Try to have a teammate bait her Gust out before you Blink and get the drop on her.
Queen of Pain
* Heroes with gap-closing abilities will be easy targets for Berserker's Call: Phantom Assassin, Faceless Void, Slark, Chaos Knight, Morphling, Queen of Pain
Additional:
* Berserker's Call prevents Queen of Pain from escaping with Blink and also pierces her Black King Bar.
* Due to her fast attack speed from 
Mjollnir, it will quickly trigger 
Counter Helix.
* 
Culling Blade finishes off Queen of Pain's low health pool before she gets a chance to escape, preventing her from playing the hit-and-run style often associated with Queen of Pain.
Pugna
* Decrepify can be used on allies to prevent them from attacking Axe and triggering Counter Helix during Berserker's Call. He can also cast it on Axe to prevent anyone from attacking him.
* Life Drain can be used to heal himself or allies caught in Berserker's Call, preventing them from dropping low enough for Axe to kill them with Culling Blade.
Queen of Pain
* Time Dilation affects Queen of Pain's low cooldown abilities, making them unusable for a long time, rendering Queen of Pain nearly useless.
* Chronosphere provides excellent lockdown against Queen of Pain, allowing for reliable kills in all stages of the game.
Additional:
* 
Time Walk and 
Backtrack allows Faceless Void to easily negate Queen of Pain's burst damage.
* 
Chronosphere prevents Queen of Pain from escaping with Blink, and her low survivability makes her an easy kill.
* 
Time Dilation will prevent Queen of Pain from using her low-cooldown spells or force her to buy Black King Bar or a Eul's Scepter of Divinity to dispel the debuff and re-engage.
Pugna
* Decrepify prevents Faceless Void from attacking trapped allies inside Chronosphere, wasting a large portion of its duration if Faceless Void can't dispel it.
Pugna
* Pugna's low health and reliance on channeled abilities make him very vulnerable to Tusk, although Pugna can win in a straight up 1v1 later in the game.
Queen of Pain
* Queen Of Pain can similliar abilities from Anti-Mage Blink allows Queen of Pain to escape from an incoming Snowball and Ice Shards.
Pugna
* Heroes who rely on channeling abilities can be interrupted in teamfights by Rolling Thunder: Crystal Maiden, Pugna, Witch Doctor
Queen of Pain
* Heroes with considerable mobility can easily escape from a rolling Pangolier: Anti-Mage, Queen of Pain, 
Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, moreover, if a player is familiar with how Rolling Thunder works, they can adjust their movement to avoid it entirely and of course outplay the Pangolier player.
Queen of Pain
* A good Skywrath Mage with quick fingers will punish Queen of Pain for blinking aggressively. 
Ancient Seal is a six second silence with no cast time, so he can interrupt either her Shadow Strike or Sonic Wave, and a good 
Mystic Flare on top of that will seal the deal for her.
* Ancient Seal also has pretty good range so he could get it off before she blinks away.
Pugna
* Due to the high mana cost of his spells and the low cool down of them, Nether Ward can seriously damage Skywrath Mage if he isn't careful.
* Skywrath Mage's fragility makes him very susceptible to Pugna's high burst damage.
Additional:
* Nether Ward will make Skywrath Mage next to useless in fights, as his low hp pool will not allow him to sustain through the damage of the ward should he choose to cast spells. Be wary though that Skywrath's huge burst will make very quick work of Pugna's low hp should the ward be destroyed, and Decrepify won't help Pugna at all.
Queen of Pain
* High priority targets like Queen of Pain, Drow Ranger, Ember Spirit can't get caught out from Lion's long range disables, making it harder to them fulfill their roles, and making it easy to target them.
Pugna
* Nether Ward will be problematic for heavy nukers and spammers like Skywrath Mage, Lina, Lion and Invoker, but Pugna must not use Decrepify defensively against them as he will be helping them out more than anything.
Queen of Pain
* Heroes that rely on their high mobility such as Queen of Pain, Slark and Weaver can be constantly engaged against due to your excellent ability to chase over any terrain. Make sure you carry true sight items (such as 
Dust of Appearance or 
Gem of True Sight) for invisible heroes that could potentially escape your clutches.
Pugna
* Pugna is a very fragile hero who can easily get caught and killed by Storm Spirit's long range initiation.
* This is especially true if he has Orchid Malevolence or Scythe of Vyse.
* Pugna has no disables that can prevent Storm Spirit from escaping.
* Even though 
Ball Lightning requires high amount of mana, Nether Ward is ineffective since Storm Spirit is invulnerable while using it.
* Storm Spirit's other abilities cost very insignificant amount of mana for Nether Ward to be effective.
Queen of Pain
* Queen of Pain outlanes Storm Spirit due to the fact that it has long-range abilities: Shadow Strike and Scream Of Pain. Storm Spirit's damage from the 
Overload ability is not enough to interrupt her on the line, and the 
Static Remnant will never reach Queen Of Pain, as she will scatter her abilities from afar, which is why she will drive Storm Spirit off the line and get a lot of gold and level, after such a stage of the liner, Queen of Pain will very quickly buy Black King Bar and will not let Storm Spirit catch and kill her at the expense of 
Electric Vortex

Pugna
* Heroes with mana burn: Nyx Assassin, Invoker, 
Outworld Destroyer, Pugna, Lion
Queen of Pain
* Blink and positioning is crucial for Queen of Pain. These factors are heavily countered by a good Glimpse.
* Static Storm is devastating for Queen as she relies heavily on her spells to inflict heavy burst damage.
Additional:
* 
Thunder Strike gives vision of Queen of Pain when she's trying to escape. When combined with 
Glimpse, her mobility and hit-and-run style can be negated.
* While in a team fight, 
Static Storm forces Queen of Pain to only use right-clicks.
* When combined with the 
Kinetic Field, she can only wait until she respawns.
Pugna
* Nether Ward can do a ton of damage to Disruptor because of his high mana costs.
* Life Drain can be used to heal an ally trapped by Static Storm-Kinetic Field combo (if Pugna is not a target).
Pugna
* Heroes with no mobility will take some good damage from Sand King's spells: 
Dragon Knight, Jakiro, Pugna, Earthshaker.
Pugna
* Pugna's Nether Ward damages Sand King when he channels Epicenter, preventing him from using Blink Dagger afterward.
Queen of Pain
* Heroes that rely on escapes to stay alive can be caught and locked down for a long time: Queen of Pain, Phantom Assassin
Queen of Pain
* Heroes that usually build Linken's Sphere as either a core or situational item: Weaver, Medusa, Morphling, Queen of Pain, Storm Spirit, Luna, Naga Siren.
Queen of Pain
* Sonic Wave is a bad choice in abilities if he and the 
Tempest Double both use Blade Mail to reflect the damage to Queen of Pain, potentially killing her outright if her health is low enough.
* 
Magnetic Field protects himself or his ally from Queen of Pain's attacks unless she has 
Monkey King Bar.
* One more advantage of Tempest Double is that he can deny himself if he is close to death with Shadow Strike's debuff.
Pugna
* Arc Warden can't use Magnetic Field to stall the damage of Nether Blast on towers, but he can buy Aghanim's Shard to diminish its damage.
* Arc Warden has no innate disables to stop Life Drain and Decrepify
* The short cooldown of both Life Drain and Decrepify also means Pugna can deal with Arc Warden and Arc Warden's clone simultaneously most of the time
* A good Pugna looks to end the match early while Arc Warden, a very item reliant hero, thrives in longer matches.
Queen of Pain
* 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.
Queen of Pain
* Heroes who commonly buy Linken's Sphere: Luna, Weaver, Morphling, Queen of Pain, Ember Spirit.
Queen of Pain
* 
Duels prevents Queen of Pain from using Blink, which may force her to purchase a Linken's Sphere
* Because Queen of Pain is also not a right-click hero, Legion won't have much difficulties in duels.
* 
Press the Attack dispels Shadow Strike's debuff.
Pugna
* Decrepify on either hero stops Legion Commander from completing a Duel, and dissuades her from initiating Duels on ethereal allies.
* Life Drain can help Pugna's teammates win a fight, either by killing Legion Commander or replenishing her target's health.
Additional:
* Decrepify prevents Legion Commander from attacking allies during Duel, regardless if it's used on her or on the ally .
* Pugna can easily cast Decrepify, Nether Blast and Life Drain on Legion during the 4/4.75/5.5/8 seconds of duel
Pugna
* Pugna's squishiness and lack of mobility make him easy prey for a Hookshot initiation.
* Clockwerk's high health, low mana costs, and lack of reliance on Blink Dagger make Nether Ward ineffective.
* Battery Assault shuts down Aghanim's Scepter upgraded Life Drain, as the repeated ministuns prevent Pugna from channeling for an extended length of time.
Additional:
* Clockwerk loves to Hookshot low health, immobile targets like Pugna.
* Pugna's Life Drain gets immediately and repeatedly (if an Aghanim's Scepter was purchased) cancelled due to 
Battery Assault, especially if Pugna is trapped inside 
Power Cogs.
* Clockwerk also loves to build Blade Mail, which will deal more damage to Pugna than Clockwerk due to Pugna's low health pool.
* Finally, both Hookshot and 
Rocket Flare can allow him to finish off Pugna out of range of his Nether Ward.
Queen of Pain
* Blink allows Quen of Pain to easily escape ganking or initiating attempts with Hookshot and Power Cogs.
Queen of Pain
*
Glaives of Wisdom's intelligence steal will heavily punish Queen of Pain, as the loss of intelligence means that her mana pool is also reduced, since she is heavily reliant on her abilities to be able to make an impact.
Arcane Curse.
Last Word and 
Global Silence will render Queen of Pain defenseless unless she has an item/ally to dispel the silence.
* In the laning stage, Queen of Pain's reliance on spamming Shadow Strike and Scream of Pain will be significantly hindered by
*
Pugna
* Pugna is very reliant on his abilities for damage which Silencer can take advantage off. But he has to be careful around the
Nether Ward as Silencer's abilities cost a lot of mana to use.
