* 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,

* Sharpshooter deals massive damage to Bristleback and applies a high duration disable on his passive.
* Bushwhack and Scurry can be used to easily kite Bristleback.
Additional:
* Bristleback and Warpath can be disabled by Hoodwink's Sharpshooter ability for a long period of time, reducing his both offense and defense.
* Scurry and Bushwhack can be used to kite bristleback.

* 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.

* Sharpshooter can kill easy when Morphling is going on full agility strategy (Only in early and mid game).
* Scurry can help to catch up Morphling when using Waveform or for escape.

* 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.

* Abaddon can be killed without triggering his ultimate Borrowed Time due to the break applied by Sharpshooter.

* 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.

* Durable heroes relied a lot on their main passive effects and items' effects such as Bristleback, Underlord, Spectre and Dragon Knight can be disabled easily with Sharpshooter's break, reducing their potential in teamfights.

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

* Sharpshooter disables both Blur and Coup De Grace, especially with the level 25 talent.
* Because Phantom Assassin is often reliant on critical strikes, Hoodwink can have enough time to simply move near a tree and escape with Scurry.
Additional:
* Sharpshooter disables both Blur and Coup De Grace, especially with the level 25 talent.
* Because Phantom Assassin is often reliant on critical strikes, Hoodwink can have enough time to simply move near a tree and escape with Scurry.

* 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.

* Huskar’s low health play style put him at extreme risk to Sharpshooter's extreme damage. In addition, it breaks Berserker's Blood, nullifying Huskar's power source.

* 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.

* Durable heroes relied a lot on their main passive effects and items' effects such as Bristleback, Underlord, Spectre and Dragon Knight can be disabled easily with Sharpshooter's break, reducing their potential in teamfights.

* Ursa struggles against heroes with strong (and especially undispellable) disables (Disruptor, Puck, Shadow Demon, Outworld Destroyer and etc).

* Heroes with evasions: Phantom Assassin, Brewmaster, Hoodwink, Windranger.

* 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

* Hex and Earth Spike do not cancel Sharpshooter, making those two abilities ineffective against her.
* Although Hoodwink should be wary of his Finger of death, as it can possibly kill her.

* Monkey King often hides in trees, where he can be easily caught with Bushwhack.
* Acorn Shot can target enemies in the fog, including Monkey King when he is on a tree.
* Sharpshooter provides flying vision along the cast indicator while charging, which can be used to scout the trees for Monkey King.

* 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'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.

* 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.

* 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.

* 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.

* 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 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.

* 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 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 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

* 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

* 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.

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

* 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 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.

* 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.

* 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.

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

* Arcane Orb and Sanity's Eclipse will make very short work of Terrorblade and his illusions.

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

* 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.

* 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.

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

* Primal Beast is mostly played in the offlane role, so picking a carry who can escape from him is essential. Heroes such as Troll Warlord, Lone Druid and Outworld Destroyer, or generally any carry with a stun, slow or ability to fight back will stop him from having the good start he needs.

* Any 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.

* Durable heroes relied a lot on their main passive effects and items' effects such as Bristleback, Underlord, Spectre and Dragon Knight can be disabled easily with Sharpshooter's break, reducing their potential in teamfights.

* 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.

* 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.

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

* Bushwhack can tear through Refraction as it does multiple intervals of damage.
