Sniper
* In the mid to late game, the physical attack from 
Sniper can be painful to go through as 
Rubick. However with the help of Rubick's teammates, the abilities of Sniper can turn against his team.
* 
Shrapnel is a great wave-clear ability, and helps with scouting the area.
* Shrapnel already has a long cast range, and together with 
Arcane Supremacy Rubick can put constant damage on Sniper while he stays at back.
* 
Assassinate, if stolen, can be cast to assist a gank while Rubick stays at a range that can merely be found in the area, damaging heroes in the backline including Sniper.
* Arcane Supremacy (combined with Level 25 talent +40% Spell Amp For Stolen Spells, as of 7.31c) increases its damage before reduction to 406.2/611.1/819(531.2/805.1/1079) without considering any further amplification source.
* With 
Aghanim's Scepter, Assassinate becomes an ability with a reliable 1.5 second stun, massive damage, short cooldown and over 3000 cast range which should not be made light of.
* Shrapnel is used frequently and can be easily stolen; Assassinate has a long cast animation for Rubick to forsee the chance to steal.
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.
Sniper
* Tinker is one of the few heroes who is able to defeat a Sniper on the center line thanks to his long-ranged abilities.
* 
Laser allow Tinker to deal damage to Sniper and blind him, causing him to miss attacks more often.
* 
Heat-Seeking Missile can deal heavy damage to Sniper on lane.
* 
Defense Matrix allow Tinker to save himself or allies from Assassinate.
* 
Warp Flare from 
Aghanim's Shard allows Tinker to teleport Sniper away from himself, while also reducing both his attack range and cast range. If Sniper is teleported near Tinker's allies with Warp Flare, he will be bursted down in no time.
Additional:
* Tinker is one of the few characters in Dota 2 who is able to defeat a Sniper on the center line – Tinker. On the center line, he gains an advantage over his opponent, and later acquires additional control. It is these abilities that the enemy should have in the game against the Sniper.
Outworld Destroyer
* 
Tinker's Laser is useful against Outworld Destroyer, as the blind prevents him from landing Arcane Orbs.
Sniper
* Lifestealer can close the distance to Sniper by using 
Infest on a fast or durable creep to tank Sniper's damage.
* 
Open Wounds and 
Ghoul Frenzy will reduce Sniper's mobility heavily, and 
Rage's movement speed bonus helps in closing the gap to Sniper. It also protects him from Assassinate and Shrapnel.
* Infest can dodge an incoming Assassinate or to surprise Sniper during ganks. Aghanim's Scepter upgraded Infest can also allow Lifestealer to disarm Sniper and attack him from inside.
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.
Sniper
* Heroes with high physical damage output but lack of reliable escape mechanisms are always a good target for a solo gank: Sniper, 
Shadow Fiend, 
Troll Warlord, 
Drow Ranger. Those heroes, however, are dangerous if they manage to close the gap, so take caution.
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.
Sniper
* Carry heroes who can close the gap reliably are very problematic: 
Phantom Lancer, 
Ember Spirit, 
Phantom Assassin.
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.
Sniper
* Magnetic Field's evasion completely negates Sniper's attacks unless he has True Strike.
* Sniper always positions himself far away from battles, which makes him especially vulnerable for Flux and Spark Wraith.
Sniper
* Sniper is completely helpless against Broodmother's abilities, and can be seriously damaged by Spiderlings in lane, especially when Shrapnel is on cooldown.
Sniper
* Sniper relies on distance. Bounty Hunter can use Shadow Walk to get close, and Jinada can do massive damage and slow down Sniper in the early game.
* Track gives additional speed to Bounty Hunter and makes 
Shadow Blade useless, which can allow Bounty Hunter to easily kill him with a few attacks.
Sniper
* Sniper's lack of mobility and escape mechanisms makes him one of the easier heroes for Bloodseeker to gank.
Sniper
* 
Headshot and Shrapnel slow is ineffective against a team with haste (which Stampede gives).
* Commonly picked up mobility items and hasted movement during his Stampede (as well as his high health pool) make him extremely hard to kill from a distance, damaging Sniper with Retaliate and 
Blade Mail if he has one.
* A low health pool and no escape mechanism makes him an easy target for Centaur Warrunner's burst damage and initiation (even making his team possible initiators with Stampede).
Sniper
* Clockwerk is also the least optimal target for Sniper to attack in a teamfight, although more experienced players will rarely make this mistake.
* With no mobility or disable skills, getting trapped in Power Cogs is a death sentence for Sniper.
Sniper
* Lina defeats Sniper on the mid, because she has the same attack range as him, and her 
Dragon Slave ability deals much more damage to creeps, as well as to Sniper himself, than Shrapnel, which creates uncomfortable conditions for Sniper to farm on the line, which is why Lina either punches Sniper harder than he either pushes a pack of creeps up to the tower and finishes off his creeps under it, preventing Sniper from earning gold and a level.

Sniper
* 
Viper Strike breaks Sniper's passives.
* 
Corrosive Skin allows Viper to deal more damage to Sniper than Sniper deals to him when laning, especially by briefly stepping into Shrapnel.
* 
Nethertoxin together with 
Poison Attack can slow Sniper and tears through his low health and mobility.
Sniper
* 
Shukuchi allows Weaver to close the gap between himself and Sniper with high speed, and to maneuver through teamfights to get on top of him.
* A combination of 
The Swarm and 
Desolator tears through Sniper's low armor.
Sniper
* Sniper has no natural escape and relies on his range and slows to keep himself safe, which Riki can bypass with Blink Strike and quickly deplete his miniature HP pool.
Sniper
* Slardar can use 
Guardian Sprint with 
Blink Dagger or Shadow Blade to get close, and 
Slithereen Crush will stun Sniper and slow him, making him vulnerable to Slardar's teammates.
* 
Corrosive Haze lowers Sniper's armor and makes Sniper's Shadow Blade useless, easily killing him with a few attacks.
Sniper
* Sniper lacks any protection against 
Lion's disables early in the game.
* Lion's 
Earth Spike and 
Finger of Death may roughly hit Sniper at the latter increased attack range, making it possible to gank and to disable him from afar in clashes.
* Finger of Death is incredibly dangerous for Sniper as it may shred him away from fights, or in the worst scenario, cause his death.
Sniper
* 
Shadow Step and 
Haunt from Aghanim's Scepter instantly allows Spectre to get up and close with Sniper, and 
Spectral Dagger makes it difficult for Sniper to escape from her.
Additional:
* Spectre can reach him easily in the backlines with Spectral Dagger or teleport to him with Haunt.
* He is usually a fair distance away from his allies, so 
Desolate will quickly tear Sniper down.
* 
Dispersion reflect or reduce his damage, making her hard to take down even at late game.
Sniper
* Sniper has no spells to disable Puck. He lacks a silence to prevent spell casting and a stun to disable, allowing Puck to act instantly against Sniper.
* Sniper's main strategy is to attack his enemies from a safe distance. Illusory Orb, combined with Blink Dagger makes it easy for Puck to get close to Sniper. Due to his low health, he is also easily nuked down by Puck.
* The status debuff placed by Assassinate on its target makes it very easy to avoid it. Puck has 2 (3 when having Blink Dagger, 4 when having 
Eul's Scepter of Divinity, 5 when having 
Linken's Sphere) methods to disjoint or dodge the projectile, making it a bad spell for finishing off Puck.
Sniper
* 
Snowball allows Tusk to move himself and allies towards Sniper whilst invulnerable and hidden.
* His 
Ice Shards may also block pathing for Sniper as he has no means of moving through obstacles. In addition, 
Tag Team can hinder Sniper's escape.
Additional:
* Tusk alone or with his teammates can close Sniper's long range easily with Snowball, even wasting Shrapnel, ending with a very vulnerable Sniper.
* Walrus PUNCH!'s very high physical damage output can easily kill Sniper instantly due to his low health and armor.
Sniper
* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: 
Batrider, 
Disruptor, 
Pudge, 
Vengeful Spirit.
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.
Sniper
* Fortune's End can catch out or impair position-based heroes with low mobility, such as Sniper or 
Razor.
Sniper
* 
Clinkz, Sniper, 
Lone Druid, Troll Warlord, 
Legion Commander and 
Wraith King are some of the Heroes that base themselves on attacks with little or no spell power, so they suffer in the grassy hands of Overgrowth.
Outworld Destroyer
* Any heroes with silences can negate the majority of Outworld Destroyer's damage output: 
Death Prophet, 
Night Stalker, Drow Ranger, 
Doom .
Sniper
* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: Batrider, Disruptor, Pudge, Vengeful Spirit.
Sniper
* Sand King is a strong ganker, allowing him to shut down squishy heroes in the early game: Phantom Assassin, Clinkz, Sniper, 
Enchantress.
Sniper
* Invisible heroes all have the element of surprise. Provided they deal enough damage, Sniper should be vanquished very quickly: Clinkz, 
Riki, 
Bounty Hunter.
Sniper
* Low-health, normally mobile carries who rely entirely on raw attack damage are vulnerable to Bane's nukes and disables: 
Anti-Mage, Clinkz, Drow Ranger, 
Faceless Void, 
Gyrocopter, Juggernaut, 
Meepo, 
Mirana, 
Monkey King, 
Morphling, Phantom Assassin, Phantom Lancer, Riki, Shadow Fiend, 
Slark, Sniper, 
Terrorblade, Troll Warlord, 
Weaver.
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.
Sniper
* Marci can be effective against vulnerable squishy heroes that cannot deal with heroes that jump onto them - Sniper, Drow Ranger, 
Lina, Rubick, etc.
Sniper
* Heroes with high mobility can approach Sniper: Anti-Mage, 
Earth Spirit, 
Io, 
Nature's Prophet, 
Pangolier, Puck, Queen of Pain and most notably Riki.
Sniper
* Other heroes that rely on physical attacks to deal damage and not their abilities: Troll Warlord, Sniper, Monkey King, 
Sven.
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.
Outworld Destroyer
* Any heroes with silences can negate the majority of Outworld Destroyer's damage output: Death Prophet, Night Stalker, Drow Ranger, Doom .
Sniper
* Heroes with high mobility can approach Sniper: Anti-Mage, Earth Spirit, Io, Nature's Prophet, Pangolier, Puck, Queen of Pain and most notably Riki.
Sniper
* You can easily kill a squishy Sniper, due to your high movement speed and his lack of escape.
Sniper
* Heroes with high mobility can approach Sniper: Anti-Mage, Earth Spirit, Io, Nature's Prophet, Pangolier, Puck, Queen of Pain and most notably Riki.
Sniper
* Invoker's arsenal of magical spells are troublesome for Sniper who has low HP and high armor, which does not benefit him much against Invoker.
* Besides magical damage, he can be disarmed and repeatedly mini-stunned with 
Cold Snap, preventing him from reacting.
* Leveling 
Quas can allow Invoker to lane effectively against Sniper despite right-click harassment.
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.
Sniper
* Heroes with powerful nuke can waste their precious abilites on her Refraction during a ganking attempt or chaos combat: Lich, Lina, Sniper, Outworld Destroyer Zeus
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.
Sniper
* Sniper destroys Templar Assassin Refraction's only defense with its Shrapnel ability, which is why it can easily punch it and kick it off the line, getting more level and gold.
* The huge range of Sniper's attack due to the 
Take Aim ability allows him to spend the whole game at a distance far from Templar Assassin, constantly punching her with his physical attacks, which is why Templar Assassin remains either to run away or hide in 
Meld, however, even there Sniper will not let her escape with the help of Blink Dagger, since he uses Shrapnel.

Sniper
* Range-reliant heroes: Sniper, Drow Ranger
Sniper
* Sniper's lack of mobility and reliance on attack range makes him an easy target for Phantom Assassin to jump on.
Additional:
* 
Stifling Dagger and 
Phantom Strike allow Phantom Assassin to close the gap with Sniper and prevent his escape.
* 
Blur allows Phantom Assassin to approach Sniper while invisible and dodge much of Sniper's damage. It can also disjoint Assassinate.
* 
Coup De Grace quickly cuts through Sniper's low health; one or two procs will usually kill him.
* 
Fan of Knives from Aghanim's Shard can deal damage to Sniper's maximum health and disable Headshot and Take Aim.
Outworld Destroyer
* Any heroes with low mana pools will die quickly or even instantly to Sanity's Eclipse: Doom, Phantom Assassin, Troll Warlord.
Sniper
* Primal Beast is one of Sniper's greatest counters, as he has no real means of escape and is very squishy, especially in the early game. Sniper's potshots and Shrapnel can contribute to Primal Beast's Uproar and further make him tankier than he already is. Onslaught allows him to close the gap on Sniper at his own volition, and Trample can deal serious damage to his meager health pool.
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.
Sniper
* Sniper is very fragile and has low movement speed, making an exceptionally easy target for Chaos Knight to initiate on.
* Sniper has no innate ability to deal with 
Phantasm or escape a 
Reality Rift and 
Chaos Bolt combo.
* In most cases, Sniper likes to stay far in the backline to deal damage, thus he is vulnerable if Chaos Knight manages to jump on him in the back line, which will usually spell a quick end for Sniper.
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.
Sniper
* His increased attack range makes it very hard to get close enough for Static Link, Eye of the Storm and Razor's own attacks.
* Headshot procs will slow Razor heavily regardless of Storm Surge, as it will knock him back for a brief duration.
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.
Sniper
* With his Take Aim, Sniper can simply sit out of your ability range and deal massive damage if not killed first.
* Assassinate can target allies who are still alive with low health because of Ghostship's buff.
* Headshot makes it harder for Kunkka to position/escape and makes it hard for Kunkka to hit with Tidebringer.
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.
Sniper
* Shrapnel can be used to disable Earthshaker's Blink Dagger from long range.
* Take Aim allows Sniper to harass Earthshaker in lane, and stay out of Echo Slam initiation radius.
Additional:
* Sniper is able to kite Earthshaker with his very long range.
* Sniper can dodge Earthshaker's stuns like 
Fissure and 
Enchant Totem with mobility items such as Blink Dagger, 
Force Staff/
Hurricane Pike and Shadow Blade/
Silver Edge.
* Sharpnel can be used to cancel Earthshaker's Blink Dagger and preventing effective use of his 
Echo Slam in a majority of situations.
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.
Sniper
* Take Aim extends Sniper's attack range, allowing him to position himself safely behind his team, making it difficult to catch him in Enigma's relatively small area-of-effect for 
Black Hole. When left unattended, he can quickly kill a channeling Enigma (often from the high ground) to rout an otherwise strong initiation.
* In the early game, Sniper can cancel Enigma's Black Hole with Assassinate's ministun. Due to the absolutely ginormous 3000 cast range on Assassinate, Sniper does not need to be too close to Enigma to cancel his Black Hole. Aghanim's Scepter upgraded Assassinate can also stun Enigma for a longer duration.
* Both Shrapnel and Assassinate put Enigma's Blink Dagger on cooldown, potentially forcing him to prematurely activate 
Black King Bar.
Additional:
* Sniper has a very long range, so it is rare that Enigma can catch him in a Black Hole.
* Assassinate can easily cancel Black Hole if he is not caught, especially with Aghanim's Scepter.
* Enigma's Eidolons from 
Demonic Conversion are useless to push against a Sniper as he will easily kill them, especially with 
Mjollnir, a common item on Sniper.
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.
Sniper
* Heroes that can easily bypass Chen's creeps to get to Chen: Riki, Tusk, Clinkz, Sniper, Slark, Phantom Assassin, 
Void Spirit, 
Storm Spirit, Ember Spirit, Earth Spirit, 
Spirit Breaker.
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.
Sniper
* Sniper just doesn't give Huskar a chance, as he always just keeps his opponents at a great distance. However, in such a game you will need to have a 
Concussive Grenade and a Hurricane Pike in order to avoid the 
Life Break of Huskar
Additional:
* Sniper just doesn't give Huskar a chance, as he always just keeps his opponents at a great distance. However, in such a game you will need to have a Concussive Grenade and a Hurricane Pike in order to avoid the Life Break of Huskar
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.
Sniper
* Heroes with good counter-push abilities to clear creep waves can hinder Jakiro's early pushing ability: Death Prophet, Sniper, Tinker, 
Windranger.
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
Sniper
* Melee heroes who may struggle to get close to Sniper: Wraith King, 
Kunkka, Doom, 
Tidehunter, Underlord, Troll Warlord, and etc.
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.
Sniper
* Melee heroes who may struggle to get close to Sniper: Wraith King, Kunkka, Doom, Tidehunter, Underlord, Troll Warlord, and 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.
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.
Sniper
* Juggernaut deals most of his damage in the melee range and has no gap-closer. Sniper can easily harrass Juggernaut from afar with his long-ranged attacks and {Ability ID:Headshot|Sniper|16px} procs.Should Juggernaut decide to advance,Sniper has enough time to react and back off.
* Sniper's long range attack can destroy 
Healing Ward from a safe range, preventing any healing done to Juggernaut and/or his teammates.
* However, if Sniper is badly positioned, Juggernaut can easily terminate him.
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.
Sniper
* Heroes that outrange Luna can be a problem for her: Drow Ranger, Sniper.
Outworld Destroyer
* Every hero that can withstand or prevent Eclipse at level 7: Juggernaut, Riki, 
Clockwerk, Drow Ranger, 
Abaddon, Faceless Void, Weaver, Outworld Destroyer.
Sniper
* Melee heroes who may struggle to get close to Sniper: Wraith King, Kunkka, Doom, Tidehunter, Underlord, Troll Warlord, and etc.
Additional:
* Shrapnel and Headshot allows Sniper to kite Troll Warlord effectively.
* Take Aim together with certain items such as Hurricane Pike allow Sniper to sit and fire at Troll Warlord from a safe distance.
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.
Sniper
* Melee heroes who may struggle to get close to Sniper: Wraith King, Kunkka, Doom, Tidehunter, Underlord, Troll Warlord, and etc.
Additional:
* Sniper's very long range allows him to stay out of 
Firestorm, 
Pit of Malice as well as 
Atrophy Aura's range.
* Escapes with 
Fiend's Gate can be canceled with Assassinate that can mini-stun the target.
* However, Fiend's Gate can be used to quickly close the gap on Sniper, and kill him if Underlord brings his allies with him through Fiend's Gate. And Sniper has nothing to intercept arrivals with Fiend's Gate outside of Shrapnel and Concussive Grenade from Aghanim's Shard.
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.
Outworld Destroyer
* Any heroes with silences can negate the majority of Outworld Destroyer's damage output: Death Prophet, Night Stalker, Drow Ranger, Doom .
Sniper
* Due to the nature of the hero, Sniper is typically situated in the back of the fight, potentially making him a difficult target to initiate on and fight.
* Sniper is largely a right-click hero, and as such isn't as an effective of a Doom target as other heroes.
* Thanks to Shrapnel and Headshot, Sniper is able to effectively 'kite' Doom, preventing him from closing the distance between the two.
Outworld Destroyer
* Any heroes with low mana pools will die quickly or even instantly to Sanity's Eclipse: Doom, Phantom Assassin, Troll Warlord.
Sniper
* Sniper can easily destroy 
Plague Ward from long range.
Sniper
* Sniper's position in the far back line makes him unlikely to be hit by any of Grimstroke's abilities during teamfights.
* Sniper is relatively unaffected by the silence from Phantom's Embrace.
* Sniper's long range and fast projectile speed allows him quickly to destroy any Phantoms attacking his allies.
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.
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 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
* 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
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.
Sniper
* Shrapnel can be used to cancel Shadow Fiend's Blink Dagger from a huge range.
* Take Aim and Headshot allow Sniper to harass Shadow Fiend in lane without getting into the range of his Shadowrazes.
Additional:
* Shrapnel can be used to cancel Shadow Fiend's Blink Dagger from a huge range.
* Take Aim and Headshot allow Sniper to harass Shadow Fiend in lane without getting into the range of his 
Shadowraze.
* Assassinate when upgraded with Aghanim's Scepter can be used to cancel Shadow Fiend's 
Requiem of Souls.
Outworld Destroyer
* Outworld Destroyer's pure damage will mop up Primal Split's units very quickly.
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.
Sniper
* Sniper can easily destroy 
Tombstone from long range.
Sniper
* A Sniper who is somewhat competent at positioning is hardly going to be affected by any of Dark Seer's spells thanks to Take Aim.
* However, an illusion of Sniper made with Wall of Replica is extremely powerful, and hard to deal with.
Sniper
* Sniper can easily destroy 
Mass Serpent Wards from long range.
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
* 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.
Sniper
* Sniper can outrange both Medusa's arrows and Stone Gaze, allowing him to focus her down during a teamfight.
Additional:
* Medusa is a fairly immobile hero that deals damage around her with 
Split Shot. Sniper should outrange her and should stay out of harm's way from Split Shot.
* More importantly, Sniper should have enough attack range to fire at Medusa during her 
Stone Gaze without turning to stone, so the ultimate is mostly wasted against him.
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.
Sniper
* Heroes who have high health are a problem for Sniper because he likes to attack the closest target and sit at the back, much like a Terrorblade so when that hero doesn't die; he's forced to show his position for a very long time: 
Centaur Warrunner, Legion Commander, 
Primal Beast.
Additional:
* Sunder can save himself or his allies from Assassinate.
* Sniper relies on right-clicks to deal damage in the late game, and Terrorblade's high armor can reduce his damage significantly.
* Terrorblade is a far harder carry than Sniper is, so a well-farmed Terrorblade can easily defeat a Sniper.
Sniper
* Unlike with other heroes who can summon illusions of themselves, Terrorblade's illusions from 
Conjure Image have different colors than other illusions which can be seen even by enemy team, which can also make Terrorblade weak even against heroes he naturally counters: 
Bane, Lifestealer, 
Spectre, Chaos Knight, Spirit Breaker, Sniper. Terrorblade's only solution to counter this problem is to get 
Manta Style as quickly as possible.
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.
Sniper
* Heroes that can maintain vision on Monkey King can see when he uses Tree Dance: 
Bloodseeker, Treant Protector with Eyes In The Forest, Sniper, Weaver
Sniper
* Pangolier can easily get close to Sniper with Swashbuckle and Rolling Thunder, negating Sniper's range advantage.
* Lucky Shot disarms Sniper and leaves him unable to effectively fight back.
Sniper
* Powerful physical hitters that can destroy Pangolier during his rolling from afar: Drow Ranger, Sniper, 
Templar Assassin, 
Arc Warden
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
* 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.
Sniper
* Long ranged heroes like Sniper or Drow Ranger can kite Tiny effectively if he doesn't get the jump on them first.
Sniper
* Heroes with channeled abilities which Assassinate may cancel at long range: Witch Doctor, 
Crystal Maiden, 
Shadow Shaman, Pugna
Sniper
* Frail heroes who lack mobility can also be an easy target to lock down with Chronosphere, such as Drow Ranger, 
Luna, Sniper, Terrorblade.
Sniper
* Heroes that can easily kill Faceless Void from outside his Cronosphere; Sniper, Skywrath Mage, etc.
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.
Sniper
* Heroes with channeled abilities which Assassinate may cancel at long range: Witch Doctor, Crystal Maiden, Shadow Shaman, Pugna
Sniper
* Axe can easily close the distance to Sniper with Blink Dagger.
* With 
Berserker's Call in combination with 
Counter Helix and 
Battle Hunger, Axe can make short work of Sniper, finishing him off easily with 
Culling Blade due to his low HP & high attack speed in the late game.
Sniper
* Ranged heroes that can easily harass Axe: Drow Ranger, Sniper, Lion.
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.
Sniper
* Heroes with long ranged attacks or abilities can harass Visage from afar like Phoenix and Sniper.
Sniper
* Squishy core heroes (Shadow Fiend, Sniper, etc)
Sniper
* Shrapnel can sometimes scout out Magnus and also place his Blink Dagger on cooldown. Aside from that, Sniper likes to stay far back behind enemy lines, so it's difficult to catch him with Reverse Polarity unless you already have vision on him and can Skewer him to the rest of his team.
Outworld Destroyer
* Any heroes with high intelligence, such as Invoker and Pugna.
Sniper
* 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.
Sniper
* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: Batrider, Disruptor, Pudge, Vengeful Spirit.
Sniper
* Sniper can kill Disruptor while he is trapped by Kinetic Field from a long range.
* Sniper generally stays in the back, making it hard for Disruptor to cast any of his skills on him in lane.
Sniper
* Heroes with high mobility can approach Sniper: Anti-Mage, Earth Spirit, Io, Nature's Prophet, Pangolier, Puck, Queen of Pain and most notably Riki.
Sniper
* Take Aim and Assassinate allow Sniper to reach Io even if it stays in the backline.
Sniper
* Past the early game, Sniper is an easy target for Sven to jump on with Aghanim's Scepter upgraded 
Storm Hammer, Blink Dagger, Silver Edge or 
Harpoon, common items on Sven.
* Sven's high armor and health pool makes it difficult for Sniper to focus, as his main source of damage is his right click, especially if Sven uses 
Warcry.
* Sniper is very squishy, and will not stand a chance against Sven head on.
Sniper
* Special mention to Sven as he may not be able to get close, but if he does, 
God's Strength will make very short work of Sniper.
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.
Sniper
* Morphling's high mobility allows him to easily get close to Sniper, who likes to keep his distance from enemies.
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.
Sniper
* Sniper's Take Aim can be wasted with either Muerta's 
Pierce the Veil or a well aimed 
Dead Shot.
* Dead Shot can displace Sniper from safe spots into the offensive range of Muerta's team, leading to potential kills on Sniper.
* Sniper relies heavily on his basic attacks, which is useless against Pierce the Veil.
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.
Sniper
* 
Ensnare with her attacks allows Naga Siren to gank Sniper easily.
* Rip Tide removes Sniper's very little armor.
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.
Sniper
* Even if he can slow Mars down with Shrapnel and Headshot, Mars can tank Sniper's physical damage simply by facing him with Bulwark, allowing him to endure his auto-attacks into the late-game. Should Sniper choose to attack someone else, Mars can redirect his projectiles with Bulwark's active ability.
* Sniper's poor mobility makes him very vulnerable to Arena of Blood, especially in the early game. Mars can also take advantage of this by pushing him closer to the front line with Spear of Mars.
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.
Sniper
* Anti-Mage can close the gap with 
Blink. Sniper will struggle to escape once he is jumped on due to the lack of mobility.
* 
Counterspell reduces sniper's magic damage from Shrapnel and Assassinate. The active component can also reflect the projectile back to sniper if he dares to target Anti-Mage. This is seriously detrimental for Sniper as he is prone to buying 
Khanda to boost effects of the Assassinate.
* Sniper often relies on mana to use items for escaping, and his abilities cost a lot of mana. 
Mana Break drains Sniper's mana and takes away Sniper's means to disengage.
* Anti-Mage has faster farming speed. He can outfarm and get ahead of Sniper easily.
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.
Sniper
* Storm Spirit can close the distance towards Sniper very easily with his ultimate 
Ball Lightning.
Additional:
* Sniper is very squishy and cannot deal with heroes that jump onto him and lock him down. Storm Spirit closes the gap in a fight against Sniper, and Sniper has no way to escape except for some items.
* Storm Spirit can dodge Assassinate with a correctly timed Ball Lightning.
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
Sniper
* Sniper has a low health pool and strength gain, making him vulnerable to Pudge's magical and pure damage.
* Sniper usually likes to deal damage away from the fight, and Meat Hook is capable of bringing him to the front lines.
* Assassinate won't do much damage against Pudge because of his high strength gain and the strength bonuses from Flesh Heap.
* Shrapnel will be mostly blocked by Flesh Heap's active.
Additional:
* Pudge's 
Meat Hook allows him to bring Sniper in the middle of any fight, and the pure damage does well against his high armor and low health.
* 
Dismember can lock Sniper down, which makes him highly vulnerable and gives enough time for Pudge to kill him alone. Aghanim's Shard upgraded Dismember will also allow Pudge to save an ally from Assassinate.
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.
Sniper
* Sniper hugely lacks mobility and escape abilities so that he is an easy target for ganks from Slark.
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.
Outworld Destroyer
* Any heroes with silences can negate the majority of Outworld Destroyer's damage output: Death Prophet, Night Stalker, Drow Ranger, Doom .
Sniper
* Heroes who outrange Drow Ranger such as Sniper, Tinker.
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.
Sniper
* Due to Sniper having a such a long range, he will rarely get hit by any of Silencer's spells.
* Global Silence will not hinder Sniper much as other heroes since most of his damage output comes from his attacks.
Additional:
* Sniper is a pure right click carry with a very long range, making it hard for Silencer to cast any of his skills on him in lane. During team-fights, Global Silence has little impact on Sniper.
Sniper
* Spirit Breaker can charge towards Sniper from anywhere on the map with 
Charge of Darkness.
* 
Greater Bash deals magical damage, which can prove dangerous to Sniper and his low health.
* Both previous abilities combined with 
Nether Strike ensures that Spirit Breaker can easily solo kill Sniper.
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.
Sniper
* Sniper's low mobility and lack of defensive abilities make him an easy gank target for the entire game, especially if Blink Dagger is picked up.
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.
Sniper
* Ember Spirit can close the distance between Sniper easily with his 
Activate Fire Remnant and further keep Sniper in place with 
Searing Chains.
* With the help of Aghanim's Scepter, Sniper cannot outrun Ember Spirit or chase him, even if Sniper builds mobility items.
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.
Sniper
* Early game gankers can make life very difficult for a Sniper if he keeps being caught: 
Ursa, Pudge, Earth Spirit.
Outworld Destroyer
* Ursa struggles against heroes with strong (and especially undispellable) disables (Disruptor, Puck, Shadow Demon, Outworld Destroyer and etc).
Sniper
* Being mostly a physical damage dealer, Sniper's effectiveness is greatly reduced by Omniknight's 
Guardian Angel.
* Omniknight's 
Degen Aura allows him to slow sniper and catch him. Sniper has to then use some escape item.
* Omniknight can also protect an ally from being finished off by Assassinate by using 
Purification and 
Repel which grants a massive strength boost.
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.
Sniper
*
Assassinate is easy to reflect with Spiked Carapace for massive damage.
Shrapnel's area damage can set up an easy stun with Spiked Carapace, especially when combined with Vendetta.
*
* In the early game, Sniper's low health pool and high intelligence makes him easy prey for Nyx Assassin.
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.
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.
Mind Flare.
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.
*
* An ill-timed
Additional:
* Outworld Destroyer's high intelligence makes him a good target for
* If timed correctly,
