* 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.

* Arcane Orb's pure damage ignores Mars' Bulwark.
* Astral Imprisonment can be used to stop Mars from being disruptive or save allies from his abilities.
* Sanity's Eclipse deals high damage to Mars, due to his low intelligence pool.

* 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

* Arcane Orb's pure damage ignores Timbersaw's Reactive Armor.
* Astral Imprisonment, if timed correctly, can interrupt Timber Chain, preventing him from escaping.
Additional:
* Arcane Orb deals constant pure damage, which bypasses Timbersaw's Reactive Armor.
* Sanity's Eclipse can hit targets inside Astral Imprisonment, which helps Outworld Destroyer finish off Timbersaw before he escapes with Timber Chain. It can also drain his mana, limiting his ability to escape should he survive.

* 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.

* Outworld Destroyer's pure damage from Arcane Orb can go through Cold Embrace.
* Outworld Destroyer can negate the healing from Cold Embrace using Astral Imprisonment, and steal mana while doing so.
* Outworld Destroyer's damage during Winter's Curse is reduced due to Arcane Orb being unable to target allies.
Additional:
* Winter Wyvern must never put her allies in Cold Embrace against Outworld Destroyer as Arcane Orb will continue to deal damage to the defenseless hero.
* Arcane Orb does not hit his allies when he is taunted by Winter's Curse, making it weak against allies, but strong versus enemies.
* Astral Imprisonment can protect a target inflicted with Winter's Curse.

* 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.

* Outworld Destroyer's pure and magical damage is particularly effective against Axe.
* Astral Imprisonment is an excellent way to defend against an initiating Axe.
* Sanity's Eclipse deals high damage to Axe due to his low mana pool.
Additional:
* Berserker's Call bonus armor doesn't block Arcane Orb's pure damage.
* Astral Imprisonment can be used to prevent an ally or Outworld Destroyer himself from an Axe initiation.
* Axe's low mana means he's susceptible to a powerful Sanity's Eclipse.

* 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.

* Astral Imprisonment can save allies from a Black Hole combo. When upgraded with Aghanim's Scepter and Aghanim's Shard, it becomes exceedingly difficult for Enigma to land a good Black Hole against Outworld Destroyer and his team.
* Astral Imprisonment can also cancel Black Hole while Enigma does not have Black King Bar.
* Arcane Orb and Sanity's Eclipse can often make a short work out of Enigma and his Eidolons.

* 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.

* Outworld Destroyer can steal more mana with Astral Imprisonment from Skywrath Mage with Shield of the Scion (granted by Aghanim's Shard). Shield of the Scion grants Skywrath Mage bonus intelligence every time he deals magic damage to an enemy hero with his abilities. The higher his intelligence, the larger his mana pool. Since Astral Imprisonment steals based on the target's max mana, Outworld Destroyer can steal much more mana from Skywrath Mage.

* 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.

* Outworld Destroyer is not exceptionally dangerous to Necrohpos because of his Ghost Shroud, but his Astral Imprisonment can save his allies from Necrophos's Reaper's Scythe, though only if he uses it at the right time, If an Outworld Destroyer is nearby, Necrophos should not use Reaper's Scythe unless he has banished himself, or has banished two heroes within 15 seconds

* Nether Blast will still hit Slark in Shadow Dance.
* Pugna can rarely target Slark directly with Decrepify, but he can 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.

* Outworld Destroyer can disrupt Slark's attacks with Astral Imprisonment either by banishing Slark or his target.
* Slark's low heathpool means he will die quickly to Arcane Orb if he is directly attacked by Outworld Destroyer
* Slark has low intelligence gain, making him easy to finish with Sanity's Eclipse if he tries to run with Shadow Dance
Additional:
* Arcane Orb deals pure damage, which ignores the armor granted from permanent agility stacks.
* Astral Imprisonment can disrupt any Pounce attempt by banishing the leashed ally.
* Slark's low mana pool makes him more susceptible to Sanity's Eclipse.

* 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

* Astral Imprisonment prevents Legion Commander from killing her opponents in Duels.
Additional:
* Outworld Destroyer can save an ally hero caught by Duel with Astral Imprisonment, and he can inflict heavy damage on Legion Commander with Arcane Orb to aid his ally. However, if he gets caught, he is unlikely to survive the duel, due to his lack of durability.

* Heroes that commonly attack etheral units do not have any problems against Muerta such as Tinker, Jakiro, Pugna or Ogre Magi

* Astral Imprisonment can waste over half of Pierce the Veil, or protect an ally from Dead Shot's fear.
* He almost always gets two charges later on, allowing him to waste the entire duration of Pierce the Veil

* Decrepify prevents Faceless Void from attacking trapped allies inside Chronosphere, wasting a large portion of its duration if Faceless Void can't dispel it.

* Any hero that can nullify effects of Chronosphere: (Keeper of the Light with Aghanim's Scepter during daytime, Winter Wyvern), banishing him or Faceless Void (Outworld Destroyer, Shadow Demon, Earth Spirit with Aghanim's Scepter) or protecting him in other ways (Dazzle, Oracle, Abaddon) can greatly limit Chronosphere's potential.

* Pugna can save allies with both healing or by making them ethereal but needs to be careful of Sven's Aghanim's Scepter purge.

* Tanky melee heroes that can easily be kited, which allows Outworld Destroyer to deal heavy damage with Arcane Orb from a distance: Sven, Underlord, Bristleback.

* Heroes who are reliant on physical damage will be nullified by Decrepify: Riki, Wraith King, Juggernaut.

* Sanity's Eclipse does massive damage to Wraith King who naturally has a low mana pool and typically doesn't build items to increase it.
* Wraithfire Blast's slow projectile speed makes it easy to avoid using Astral Imprisonment.

* 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

* Any heroes with low mana pools will die quickly or even instantly to Sanity's Eclipse: Doom, Phantom Assassin, Troll Warlord.

Additional:
* Outworld Destroyer's pure damage from Arcane Orb is very effective at killing Troll Warlord quickly.
* Astral Imprisonment removes Troll Warlord from a fight for four seconds, minimizing his contribution to a teamfight, and potentially wasting over half of Battle Trance's duration.
* Troll Warlord gains a measly 1 intelligence point per level, meaning Sanity's Eclipse is especially effective, often instantly killing him.

* Pugna: Decrepify prevent the Spirit bear from attacking or protect allies from it.

* Arcane Orb deals heavy damage to both Lone Druid and the Spirit Bear.
* Astral Imprisonment can prevent the Spirit Bear from attacking, which is Lone Druid's main damage output.
* Sanity's Eclipse deals heavy damage to Lone Druid.

* 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.

* Astral Imprisonment allows Outworld Destroyer to save himself or ally from Invoker's combo, or remove Invoker from a fight temporarily.
* Arcane Orb's pure damage will deal a lot of damage against Invoker's mediocre strength gain.
* EMP is useless against Outworld Destroyer by activating Equilibrium.
* However, be aware that Sanity's Eclipse will most likely not deal any damage at all, due to Invoker's high intelligence gain compared to Outworld Destroyer's.

* 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.

* Astral Imprisonment allows Outworld Destroyer to save himself or his teamates during Omnislash.
* Juggernaut's low mana from his low intelligence gain means that he'll take a lot of damage from Sanity's Eclipse.

* Heroes who have channeling abilities because Terrorblade has no disables to cancel them at all and does not like buying disabling items at all: Enigma's Black Hole, Witch Doctor's Death Ward, Shadow Shaman's Shackles, Lion's Mana Drain, Bane's Fiend's Grip, Pudge's Dismember, Crystal Maiden's Freezing Field, Pugna's Life Drain, Dawnbreaker's Solar Guardian, and Naga Siren's Reel In from Aghanim's Scepter.

* Most Illusion based heroes (like Chaos Knight and Terrorblade) can't use their illusion beneficially against Sanity's Eclipse's high AoE burst damage.

Additional:
* Arcane Orb deals pure damage against the real Terrorblade, which allows it to bypass his high base armor.
* Arcane Orb and Sanity's Eclipse will make very short work of Terrorblade and his illusions.

* Heroes that can apply early pressure before Phantom Assassin has farm are massive threats: Axe, Viper, Meepo, Pugna, Slark etc.

* Any heroes with low mana pools will die quickly or even instantly to Sanity's Eclipse: Doom, Phantom Assassin, Troll Warlord.

* Sanity's Eclipse only triggers Bristleback's passive once, and deals high damage against Bristleback's low intelligence.
* Outworld Destroyer's high burst damage is not negated by Bristleback's passive, So even if Bristleback turns his back on Outworld, Outworld Destroyer can decimate Bristleback quickly,
* If Bristleback attempts to flee, or tries to close the gap, Outworld can banish him with Astral Imprisonment, both reducing Bristlebacks much needed mana, and allowing Outworld to move in front of him, forcing him to take the full damage from his spells, This will also allow Outworld to land a devasting Sanity's Eclipse, without it being reduced by Bristleback's passive,

* Arcane Orb deals pure damage, effectively bypassing Morphling's high armor from Attribute Shift (Agility Gain).
* Sanity's Eclipse is more effective against a low health and mana pool Morphling, enabling Outworld Destroyer to burst Morphling down before he can shift to Strength.
Additional:
* Arcane Orb deals high damage regardless of Morphling's high armor from Attribute Shift (Agility Gain).
* Because of Morphling's very low intelligence gain and base intelligence, Sanity's Eclipse will almost always be effective against Morphling.

* Arcane Orb's constant pure damage output is devastating to Dragon Knight.
* Dragon Knight's relatively low mana pool leads to heavy damage from Sanity's Eclipse, which also bypasses his armor.

* 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.

* Astral Imprisonment can allow Outworld Destroyer to save himself or allies from Kunkka's full kit.
* Sanity's Eclipse deal a large amount of damage, as Kunkka's mana pool is much smaller than Outworld Destroyer's.
* Arcane Orb deals pure damage, shredding through Kunkka and his team even with Ghostship's buff.

* 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.

* 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).

* The pure damage provided by Arcane Orb is a great addition for killing Ember Spirit.
* Astral Imprisonment fully negates all magic damage of Flame Guard and Searing Chains and will temporarily save himself from Sleight of Fist's physical damage, and Ember Spirit is not a hero that can counter these skills.

* Astral Imprisonment can be used to protect allies by imprisoning either them or Spirit Breaker.
* Arcane Orb will heavily drain Spirit Breaker's intelligence, rendering him almost useless and unable to cast spells. Spirit Breaker's low intelligence also means Sanity's Eclipse will deal a lot of damage to him.

* Kraken Shell's dispel does not restore mana lost through Astral Imprisonment, and the stolen mana can really hurt Tidehunter's ability to initiate
* Arcane Orb high pure damage ignores Tidehunter's Armor, and is barely affected by his Kraken Shell's damage block
* It is also completely unaffected by Anchor Smash, due to it relying on Outworlds Mana pool
* Sanity's Eclipse is effective on Tidehunter's poor mana pool, While it is reduced by Kraken Shell, the damage reduction is negligible.

* 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.

* 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.

* 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.

* Astral Imprisonment wastes Borrowed Time's duration.
* Outworld Destroyer's Sanity's Eclipse can kill Abaddon before Borrowed Time triggers due to the lack of intelligence for Abaddon.

* Sanity's Eclipse will likely instantly kill all illusions.

* 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.

* Outworld Destroyer doesn't care if Razor steals his damage because he does most of his damage through Arcane Orb.
* Astral Imprisonment can prevent Razor from using the stolen damage from Static Link or chasing with Eye of the Storm.
* Sanity's Eclipse will do a ton of damage to Razor due to his low mana pool.

* Astral Imprisonment is a versatile nuisance:
* If it is cast on a low-enough-health unit at least 1 second into Shallow Grave's duration, the Shallow Grave will end during the imprisonment, and the target will take lethal damage when released.
* It can be used remove Dazzle from the fight at a time he could have saved someone.
* It lets himself or an ally dodge all of Poison Touch's effects, for long enough to recover their Blink Dagger.

* Outworld Destroyer's pure damage will mop up Primal Split's units very quickly.

* 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.

* Arcane Orb's pure damage penetrates Guardian Angel's defense.
* Astral Imprisonment's mana steal is devastating to Omniknight's already low mana pool.

* 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.

* 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.

* Shadow Demon, Outworld Destroyer and Tusk can all save a Lasso'd teammate with their defensive spells.

* 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.

* 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.

* 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.

* 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.

* Tanky melee heroes that can easily be kited, which allows Outworld Destroyer to deal heavy damage with Arcane Orb from a distance: Sven, Underlord, Bristleback.

Additional:
* Arcane Orb 's pure damage can do great damage to Underlord.
* Sanity's Eclipse can tear down Underlord's health by a large amount, since his mana pool is very low compare to OD's high mana pool.

* Heroes with channeling spells, for Chen has no disables on his own, hates buying disabling items and his creeps are often not fast enough to cancel them: Enigma's Black Hole, Witch Doctor's Death Ward, Shadow Shaman's Shackles, Lion's Mana Drain, Bane's Fiend's Grip, Pudge's Dismember, Crystal Maiden's Freezing Field, Pugna's Life Drain, Dawnbreaker's Solar Guardian, and Naga Siren's Reel In from Aghanim's Scepter.

* Heroes with pure damage can kill Huskar when he inevitably gets low on health: Outworld Destroyer, Silencer.

Additional:
* Outworld Destroyer can dodge Life Break with Astral Imprisonment, leaving him unharmed while Huskar loses HP.
* Sanity's Eclipse can deal massive damage to Huskar before he builds up his Berserker's Blood stacks due to Huskar's low mana pool.

* Heroes that can protect or dispel stunned allies such as Legion Commander, Outworld Destroyer, Shadow Demon and Oracle can reduce the effectiveness of Sacred Arrow.

* Heroes who are reliant on physical damage will be nullified by Decrepify: Riki, Wraith King, Juggernaut.

* 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.

* Astral Imprisonment protects an ally for much of Rolling Thunder's duration, especially at the lower levels. As Rolling Thunder has a considerable cast animation, an Outworld Destroyer with Blink Dagger can initiate on him and destroy his timing.

* Sanity's Eclipse deals more damage the less max mana the heroes hit by it have, making Pudge an ideal target.
* Outworld Destroyer can save allies or himself caught by Dismember or Meat Hook with Astral Imprisonment.

* Outworld Destroyer's pure and magical damage is particularly effective against Earthshaker.
* Astral Imprisonment catches Earthshaker while he blinks in, preventing him from executing his combo.
* Earthshaker has mana troubles, and Outworld Destroyer's abilities can press this by stealing intelligence comes from Arcane Orb, therefore depleting his mana pool and mana regeneration.
* Sanity's Eclipse deals high damage to Earthshaker, due to his low intelligence and mana pool.

* Nether Ward discourages Tinker from using abilities and items due to its high damage against heavy mana usage.

* Heroes with mana burn: Nyx Assassin, Invoker, Outworld Destroyer, Pugna, Lion

* Heroes with mana burn: Nyx Assassin, Invoker, Outworld Destroyer, Pugna, Lion

* Any heroes with low mana pools will die quickly or even instantly to Sanity's Eclipse: Doom, Phantom Assassin, Troll Warlord.

* 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.

* 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.

* Heroes with hiding abilities can protect disabled allies: Outworld Destroyer, Shadow Demon, Tusk, Phoenix with Aghanim's Scepter.

* Pugna's Nether Ward damages Sand King when he channels Epicenter, preventing him from using Blink Dagger afterward.

* Astral Imprisonment can be used to protect allies from Jakiro's various abilities, It can also be cast on Jakiro to break his combos (Macropyre into Ice path into Dual Breath), while at the same time, stealing his much needed mana.
* Once he gets his Scepter and Shard, not only does he get two charges, he and his allies can move while imprisoned, which allows them to leave the area of your spells
* His Astral Imprisonment/Meteor Hammer combo combined with his high pure damage can quickly decimate Jakiro, And unlike most heroes, Outworld doesn't particularly care who he targets.
* Outworld is also a common Black King's Bar carrier

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

* Arcane Orb's pure damage, making Counterspell ineffective.
* Sanity's Eclipse will hit Anti-Mage while he is disabled from Astral Imprisonment, and forces him to take heavy damage due to his low intelligence.
* Essence Flux keeps Outworld Destroyer at high mana, thus greatly reducing the damage from Mana Void.
Additional:
* Counterspell doesn't work versus Arcane Orb because it does pure damage.
* Anti-Mage cannot burn all of Outworld Destroyer's mana without disables due to Essence Flux.
* Anti-Mage's Manta Style illusions are quickly destroyed by Arcane Orb.
* However, if the enemy has multiple means of removing mana, Mana Void becomes a threat to Outworld Destroyer, Anti-Mage has better mobility than Outworld Destroyer with Blink, and Counterspell blocks a large portion of the damage from Sanity's Eclipse.
