Tiny
* Long ranged heroes like 
Sniper or 
Drow Ranger can kite Tiny effectively if he doesn't get the jump on them first.
Outworld Destroyer
* As Outworld Destroyer has short cast ranges, a short attack range, and no gap-closing abilities, Sniper can kite and harass Outworld Destroyer in lane with his long range and zone him out in fights. The continuous area damage from 
Shrapnel also prevents Astral-Blink escapes.
* However, in the late game, Outworld Destroyer's massive damage can overwhelm Sniper once he obtains 
Blink Dagger, 
Force Staff etc. to close the gap.
Tiny
* Long ranged heroes like Sniper or Drow Ranger can kite Tiny effectively if he doesn't get the jump on them first.
Outworld Destroyer
* Any heroes with silences can negate the majority of Outworld Destroyer's damage output: 
Death Prophet, 
Night Stalker, Drow Ranger, 
Doom .
Tiny
* Heroes with Evasion or abilities that cause Tiny to miss like 
Phantom Assassin and 
Tinker are very effective because of Tiny's low attack speed. Additionally, 
Monkey King Bar is not a good item for Tiny because of its reliance on high attack speed to proc for magical damage.
Outworld Destroyer
* Tinker's 
Laser is useful against Outworld Destroyer, as the blind prevents him from landing Arcane Orbs.
Outworld Destroyer
* Silencer's 
Intelligence Steal will heavily reduce Outworld Destroyer's damage output, particularly from Sanity's Eclipse.
* 
Last Word and 
Global Silence will take Outworld Destroyer out of the fight unless he has built Black King Bar.
Additional:
* Silencer's intelligence steal will heavily reduce Outworld Destroyer's damage output, especially if Destroyer dies a lot near Silencer and loses intelligence permanently.
* Global Silence and Last Word will render Outworld Destroyer helpless unless he has an item/ally to dispel silence.
Outworld Destroyer
* Outworld Destroyer's high intelligence gain and fragility makes him an easy target for a massive Mana Burn, as well as killing him outwards with Nyx Assassin's high burst damage.
* 
Astral Imprisonment can be easily exploited by Nyx Assassin with his abilities. As long as Astral Imprisonment was not cast on Nyx Assassin, it will make an opportunity for an easy stun, either by Spiked Carapace (if Outworld Destroyer hid his allies or your allies) or Impale (if he hid himself). If Astral Imprisonment was cast on Nyx Assassin, using Spiked Carapace while banished will proc the stun after the disable, since Spike Carapace has a 0 second cast time and Astral Imprisonment deals damage right after the disable ends.
* An ill-timed 
Sanity's Eclipse and/or well timed Spiked Carapace can deal a lot of damage to Outworld Destroyer and stun him, unless Outworld Destroyer used 
Black King Bar beforehand.
Additional:
* Outworld Destroyer's high intelligence makes him a good target for 
Mind Flare.
* If timed correctly, 
Spiked Carapace will return the full damage from Sanity's Eclipse back to Outworld Destroyer. Even a reflected Arcane Orb can deal significant damage and make him vulnerable to a follow-up from Nyx Assassin.
* Spiked Carapace is also the perfect tool against Astral Imprisonment: if used on Nyx, he can reflect the damage back as he comes out of the prison by casting the ability while imprisoned.
Tiny
* 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.
Outworld Destroyer
* Shadow Demon's 
Disruption will allow his allies to maneuver around you. It can also be used to protect an ally from your abilities, or Astral Imprisonment - 
Meteor Hammer combo.
* 
Disseminate turns your high damage Arcane Orb and Sanitiy's Eclipse against you and your teammates.
* Scepter upgraded 
Demonic Purge will break your Essence Flux passive for 7 seconds, preventing you from regaining mana, and severely hindering your damage output.
Tiny
* Primal Roar and the slow from Boars make kiting Tiny very easy.
Outworld Destroyer
* Rubick can use 
Spell Steal to steal Astral Imprisonment, and if Rubick gets 
Aghanim's Scepter he gets 2 charges of it. This can overpower Outworld Destroyer in team fights.
* Rubick can also steal Sanity's Eclipse against Outworld Destroyer's teammates.
Outworld Destroyer
* 
Doppelganger and 
Juxtapose allow Phantom Lancer to initiate on Outworld Destroyer, and, although Arcane Orb will normally destroy his illusions instantly, Phantom Lancer will spawn too many to deal with without using Sanity's Eclipse.
* Outworld Destroyer has very little AOE ability; His Astral Imprisonment with Aghanim's Scepter is his primary AOE, and it does too little damage to eliminate Phantom Lancer's illusions.
Additional:
* Although Outworld Destroyer will typically destroy Phantom Lancer's illusions in one shot, Phantom Lancer spawns too many of them for Outworld Destroyer to deal with. However, be careful about initating on Outworld, as Sanity's Eclipse will erase your illusions and deal massive damage to you. He can then follow up with Astral Imprisonment and Meteor Hammer.
Tiny
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (
Clinkz, 
Templar Assassin, 
Ursa, 
Wraith King etc).
Outworld Destroyer
* 
Refraction blocks most of the damage dealt with Arcane Orb and Sanity's Eclipse if used correctly, and is difficult for Outworld Destroyer to deal with.
* If Astral Imprisonment is on cooldown, then an Outworld Destroyer slowed by 
Psionic Trap is an easy kill for Templar Assassin, especially during the laning stage.
Tiny
* Heroes that have disposable area-targeted spells can force her to undo her Meld: 
Leshrac, 
Puck, 
Tiny, 
Jakiro,. An experienced Templar Assassin could try to use Refraction before Meld so she can tank through those damage without getting her Blink disabled.
Outworld Destroyer
* Any heroes with silences can negate the majority of Outworld Destroyer's damage output: Death Prophet, Night Stalker, Drow Ranger, Doom .
Tiny
* 
Blade Fury protects Juggernaut from all of Tiny's magic burst damage.
Outworld Destroyer
* Heroes with built-in spell immunity can become immune to all of Outworld Destroyer's spells: 
Lifestealer's 
Rage and 
Juggernaut's Blade Fury.
Outworld Destroyer
* 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.
Tiny
* Heroes that are able to slow Tiny's attack speed, like 
Tusk and 
Phoenix, will greatly limit his Physical damage output.
Tiny
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (Clinkz, Templar Assassin, Ursa, Wraith King etc).
Tiny
* He can quickly take out heroes with low armor (Tiny) with his great physical damage.
Outworld Destroyer
* Any heroes with silences can negate the majority of Outworld Destroyer's damage output: Death Prophet, Night Stalker, Drow Ranger, Doom .
Outworld Destroyer
* Any heroes with high intelligence, such as 
Invoker and 
Pugna.
Tiny
* Invoker is a big problem for Tiny the whole game because of its multiple disables. For example, the 
Cold Snap ability can catch an attack from Tiny's hand by surprise, because it becomes slower with the pumping of 
Grow. has a giant deceleration, creating a condition for the kite, which Tiny is very afraid of. In addition, Invoker has a 
Deafening Blast that disables Tiny's main weapon - strong blows from the hand
Additional:
* Invoker is a big problem for Tiny the whole game because of its multiple disables. For example, such as 
Tornado + 
E.M.P. create unrealistic conditions for Tiny with mana, which is very necessary for Tiny at least for some attacks in a fight. The Cold Snap ability can catch an attack from Tiny's hand by surprise, because it becomes slower with the pumping of Grow. has a giant deceleration, creating a condition for the kite, which Tiny is very afraid of. In addition, Invoker has a Deafening Blast that disables Tiny's main weapon - strong blows from the hand
Outworld Destroyer
* Any heroes with high intelligence, such as Invoker and Pugna.
Outworld Destroyer
* 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.
* E.M.P. 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.
Tiny
* Heroes that are able to slow Tiny's attack speed, like Tusk and Phoenix, will greatly limit his Physical damage output.
Tiny
* 
Chaos Bolt and 
Reality Rift makes Tiny's low mobility non existent.
* 
Chaos Strike means Chaos Knight will most likely survive longer in a duel between the two because Tiny has much lower attack speed.
* Chaos Knight has a 3.2 strength growth, making him one of the most tanky heroes and a very difficult target for Tiny to burst.
Outworld Destroyer
* Most Illusion based heroes (like 
Chaos Knight and 
Terrorblade) can't use their illusion beneficially against Sanity's Eclipse's high AoE burst damage.
Tiny
* 
Avalanche and 
Toss will never be enough damage to take out Sven in a clean way.
* Tiny is very slow with low armour growth and does not buy items to sustain Sven's damage output.
Outworld Destroyer
* 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.
Outworld Destroyer
* Batrider prevents sharp and brazen attacks of the opponent. First he catches him in a 
Flaming Lasso, and then causes huge damage, in some cases even incompatible with life.
Additional:
* Batrider prevents sharp and brazen attacks of the opponent. First he catches him in a Flaming Lasso, and then causes huge damage, in some cases even incompatible with life.
Outworld Destroyer
* 
Shadow Demon, 
Outworld Destroyer and Tusk can all save a Lasso'd teammate with their defensive spells.
Tiny
* Avalanche and Toss combo makes short work of 
Mirror Image's illusions.
* Tiny's cleave with Tree Grab and area of effect damage with Tree Volley will easily wipe out illusions.
Outworld Destroyer
* Arcane Orb allows Outworld Destroyer's attacks to deal pure damage that can bypass Naga Siren's armor, and which can clear her illusions in no time.
* Astral Imprisonment can be used to harass Naga Siren by reducing her maximum mana and to prevent Naga Siren from escaping with Song of the Siren. Outworld Destroyer can also use Astral Imprisonment to protect himself from Naga Siren.
* Sanity's Eclipse will most likely instantly kill Naga Siren along with her illusions. Even if Naga Siren survives Sanity's Eclipse, it's mana allergy debuff will discourage Naga Siren from using her abilities as the mana allergy will heal Outworld Destroyer if she uses them for it's duration.
Tiny
* Toss and Avalanche deals heavy damage to Slark in the early game, making Tiny a very dangerous target to gank.
* Tiny has 0 agility, which means Slark's 
Essence Shift permanent agility steal does not do much against him.
Outworld Destroyer
* 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.
Tiny
* Tiny can be a serious problem for the distance between Lone Druid and his 
Summon Spirit Bear with his Toss ability, since he will throw one away from the other, giving his team the opportunity to deal with either the Summon Spirit Bear or Lone Druid himself
* Lone Druid will not always be in his 
True Form, since she has her own recharge, which is why Tiny can find him with a 
Shadow Blade or Blink Dagger and kill him in a second with a combination of Avalanche and Toss, due to the fact that Lone Druid has a very small health reserve without True Form
Additional:
* Tiny can be a serious problem for the distance between Lone Druid and his Summon Spirit Bear with his Toss ability, since he will throw one away from the other, giving his team the opportunity to deal with either the Summon Spirit Bear or Lone Druid himself
* Lone Druid will not always be in his True Form, since she has her own recharge, which is why Tiny can find him with a Shadow Blade or Blink Dagger and kill him in a second with a combination of Avalanche and Toss, due to the fact that Lone Druid has a very small health reserve without True Form
Outworld Destroyer
* 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.
Outworld Destroyer
* Astral Imprisonment allows Outworld Destroyer to waste over half of 
Pierce the Veil, or protect an ally from Dead Shot's fear while also reducing Muerta's maximum mana.
* Sanity's Eclipse will deal massive damage to Muerta if her maximum mana gets too low. And even if she survives it, Sanity's Eclipse's Mana Allergy debuff will discourage her from using abilities as that will result in healing Outworld Destroyer.
Outworld Destroyer
* 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.
Outworld Destroyer
* 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.
Outworld Destroyer
* 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.
Outworld Destroyer
* 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
* Arcane Orb and Sanity's Eclipse can often kill Chen or his allies before he can save them with 
Hand of God.
* Arcane Orb, Astral Imprisonment and Sanity's Eclipse can clear waves of Chen's converted creeps.
Outworld Destroyer
* 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.
Outworld Destroyer
* 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.
Outworld Destroyer
* 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.
Outworld Destroyer
* 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.
Outworld Destroyer
* 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.
Outworld Destroyer
* 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.
Outworld Destroyer
* 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
* Outworld Destroyer has a huge damage from Arcane Orb, which is why in a 1 on 1 skirmish Storm Spirit simply cannot defeat him in damage. Since Outworld Destroyer will stop gank Storm Spirit with his Astral Imprisonment, and then kill him if he decides to fight
Additional:
* Outworld Destroyer has a huge damage from Arcane Orb, which is why in a 1 on 1 skirmish Storm Spirit simply cannot defeat him in damage. Since Outworld Destroyer will stop gank Storm Spirit with his Astral Imprisonment, and then kill him if he decides to fight
Outworld Destroyer
* 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.
Outworld Destroyer
* 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.
Outworld Destroyer
* Astral Imprisonment can be used to protect allies by imprisoning either them or Spirit Breaker.
* Arcane Orb will heavily drain Spirit Breaker's maximum mana, rendering him almost useless and unable to cast spells. And considering how Spirit Breaker's intelligence is very low, Sanity's Eclipse will deal a lot of damage to him.
* Even if Spirit Breaker survives Sanity's Eclipse, mana allergy applied by the Sanity's Eclipse will discourage Spirit Breaker from using his abilities as it will cause him to lose health and heal Outworld Destroyer.
Outworld Destroyer
* Arcane Orb's pure damage penetrates Guardian Angel's defense.
* Astral Imprisonment's mana steal is devastating to Omniknight's already low mana pool.
Outworld Destroyer
* 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.
Outworld Destroyer
* 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.
Outworld Destroyer
* 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.
Outworld Destroyer
* 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.
Outworld Destroyer
* 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.
Outworld Destroyer
* Outworld Destroyer's pure damage will mop up Primal Split's units very quickly.
Tiny
* Tiny can quickly clear Spiderlings with his active abilities and cleave.
Outworld Destroyer
* 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.
Outworld Destroyer
* Every hero that can withstand or prevent Eclipse at level 7: Juggernaut, 
Riki, 
Clockwerk, Drow Ranger, 
Abaddon, 
Faceless Void, 
Weaver, Outworld Destroyer.
Outworld Destroyer
* 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.
Outworld Destroyer
* 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.
Outworld Destroyer
* 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.
Outworld Destroyer
* 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.
Tiny
* Squishy heroes, usually supports, like 
Lion, 
Ancient Apparition, Keeper of the Light etc can die quickly to Tiny's magic burst.
Outworld Destroyer
* 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.
Tiny
* Squishy heroes, usually supports, like Lion, Ancient Apparition, Keeper of the Light etc can die quickly to Tiny's magic burst.
Tiny
* Tiny's Avalanche affects all Meepos and Toss can send a singular Meepo into death.
Additional:
* Avalanche and Toss prevents Meepo's from using 
Poof to escape.
* Tiny doesn't need to target the weakest clone while he is affected by Tree Grab.
Tiny
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (Clinkz, Templar Assassin, Ursa, Wraith King etc).
Outworld Destroyer
* 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.
Tiny
* Heroes with high base damage (
Morphling, Tiny, Drow Ranger), heroes with mana burning abilities (
Anti-Mage), and 
Diffusal Blade users (Juggernaut or Riki) will suffer from Reflection's illusions.
Outworld Destroyer
* 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.
* Aghanim's Shard upgraded Astral Imprisonment can be used to save an ally on which Terrorblade has used 
Sunder.
Outworld Destroyer
* Any heroes with silences can negate the majority of Outworld Destroyer's damage output: Death Prophet, Night Stalker, Drow Ranger, Doom .
Outworld Destroyer
* Any heroes with low mana pools will die quickly or even instantly to Sanity's Eclipse: Doom, Phantom Assassin, Troll Warlord.
Tiny
* Tiny's nonexistent armor in the early game makes him very vulnerable to 
Quill Spray's large amounts of physical damage.
* 
Bristleback decreases Tiny's high burst damage against Bristleback.
* 
Viscous Nasal Goo can slow Tiny to a crawl and allows Bristleback to easily kite him with his high movement speed and Quill Spray's long range, as Tiny has no ability to escape.
Outworld Destroyer
* Outworld Destroyer's high burst damage is not negated by Bristleback's passive. So, even if Bristleback turns his back on Outworld, he 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.
Tiny
* Dual Breath and Liquid Fire reduces Tiny's already abysmal Attack Speed.
* If Tiny Tosses a hero onto Jakiro, he can react with Ice Path, and potentially Macropyre.
* Tiny's Avalanche is easily countered with Ice Path.
* As Tiny has a very high Health, Liquid Frost is particularly effective against him.
Outworld Destroyer
* 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.
* Aghanim's Shard upgraded Astral Imprisonment allows Outworld Destroyer and his allies to move while imprisoned, which allows them to leave the area of Jakiro's abilities.
* As Outworld Destroyer is prone to buying Meteor Hammer, he can combine it with Astral Imprisonment and Arcane Orb's high pure damage that 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, and Jakiro's only tool to counter it is the Aghanim's Scepter upgraded 
Macropyre
Tiny
* 
Mana Drain has an fair long range and low cooldown. It can easily deplete most heroes of their entire mana pools, especially those with smaller mana pools such as Tiny or 
Spirit Breaker.
Additional:
* Lion can continuously Mana Drain Tiny in the early game, depleting his small mana pool for his abilities.
Tiny
* Squishy heroes, usually supports, like Lion, Ancient Apparition, Keeper of the Light etc can die quickly to Tiny's magic burst.
Tiny
* Heroes without blink mechanisms or spell immunity will have a hard time positioning against 
Pit of Malice: Sven, Tiny, Wraith King, 
Dragon Knight, 
Meepo, Doom, 
Bounty Hunter, 
Dark Seer, 
Undying, 
Alchemist, Legion Commander.
Outworld Destroyer
* 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 Outworld Destroyer's high mana pool.
Tiny
* Heroes with Evasion or abilities that cause Tiny to miss like Phantom Assassin and Tinker are very effective because of Tiny's low attack speed. Additionally, Monkey King Bar is not a good item for Tiny because of its reliance on high attack speed to proc for magical damage.
Outworld Destroyer
* Any heroes with low mana pools will die quickly or even instantly to Sanity's Eclipse: Doom, Phantom Assassin, Troll Warlord.
Tiny
* 
Reaper's Scythe will turn Tiny's high health against him.
* 
Heartstopper Aura does substantial damage to Tiny as a result of his high max health.
* 
Ghost Shroud protects Necrophos from Tiny's physical damage with Tree Grab and Tree Volley.
Outworld Destroyer
* 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
Tiny
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (Clinkz, Templar Assassin, Ursa, Wraith King etc).
Outworld Destroyer
* Ursa struggles against heroes with strong (and especially undispellable) disables (
Disruptor, Puck, Shadow Demon, Outworld Destroyer and etc).
Outworld Destroyer
* 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.
Outworld Destroyer
* Heroes with hiding abilities can protect disabled allies: Outworld Destroyer, Shadow Demon, Tusk, Phoenix with Aghanim's Scepter.
Outworld Destroyer
* Heroes who take a long time to become strong are in for a rough mid game, such as Outworld Destroyer, Magnus, Medusa, and Anti-Mage.
Tiny
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: Sven, Tiny, Wraith King, 
Ogre Magi.
Tiny
* Familiars will easily be able to kite heroes with a short range or with low attack speed. For example, Tiny and Undying have a very hard time killing Familiars.
Tiny
* Tiny can deal with 
Visage's 
Gravekeeper's Cloak quickly, as Avalanche deals damage in enough instances to completely remove all 4 layers of the passive. With Visage's lower than average Armor, a well positioned stun can allow Tiny to kill Visage easily.
Additional:
* Tiny's Avalanche removes a significant number of layers from Gravekeeper's Cloak. When combined with Toss burns through all of Gravekeeper's Cloak while doing triple times Toss damage to Visage in midair.
* Tiny's already high damage coupled with 
Tree Grab's attack modifier will make short work of Visage's Familiars.
Tiny
*
Feast will deal a enormous amount of damage because of Tiny's huge health pool.
Rage protects Lifestealer from Tiny's magical burst damage.
*
Outworld Destroyer
* Heroes with built-in spell immunity can become immune to all of Outworld Destroyer's spells:
Lifestealer's 
Rage and 
Juggernaut's 
Blade Fury.
