Witch Doctor
* Rubick can steal 
Death Ward easily as it is a channeled ability and then use it to turn teamfight to his advantage.
* However, a skilled Witch Doctor will toggle Voodoo Restoration immediately after placing his Death Ward to prevent that.
Additional:
* 
Witch Doctor's iconic Death Ward is a perfect spell for Rubick to output high damage.
* Death Ward requires channeling which makes Witch Doctor a clear tagret for stealing. Rubick can steal the spell outside of Death Ward's attack range most of the times.
* Note that an skilled Witch Doctor player can cast 
Voodoo Restoration to disrupt their last spell for Rubick to steal.
* 
Telekinesis can interrupt a channeling Death Ward. With Death Ward's high burst damage, combining Death Ward and Telekinesis to hold enemy in place can result in a solo kill in the early game.
* 
Paralyzing Cask provides an additional disable. The ability also helps moderately with farming.
* Voodoo Restoration provides some utility by healing Rubick and his team.
* 
Maledict is a damage-over-time nuke that amplifies the damage enemy taken.
* Telekinesis can reposition the enemy within the range of Maledict.
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.
Witch Doctor
* Heroes with channeled abilities which Assassinate may cancel at long range: Witch Doctor, 
Crystal Maiden, 
Shadow Shaman, 
Pugna
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.
Witch Doctor
* It is especially easy for Oracle to negate the damage from Maledict, and even heal through it with 
Fate's Edict and 
Purifying Flames.
* If by some miracle an enemy is still about to die because of Maledict, he can still save him with 
False Promise.
Witch Doctor
* Without Dust of Appearance or Sentry Wards, Riki is able to silence Witch Doctor with 
Smoke Screen, and is likely to build a Diffusal Blade, leaving Witch Doctor without mana to cast Voodoo Restoration, as well as Skull Basher to interrupt Death Ward.
Outworld Destroyer
* 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.
Additional:
* 
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.
Witch Doctor
* Vengeful Spirit has two abilities to interrupt Death Ward, even through Black King Bar.
Witch Doctor
* 
Arc Warden's 
Magnetic Field dodges all damage from Death Ward.
Witch Doctor
* Stone Form can easily interrupt heroes with long channeling spells, like Crystal Maiden, 
Bane, Witch Doctor, or 
Enigma.
Witch Doctor
* Heroes with plenty of summons, such as 
Broodmother or 
Nature's Prophet can have their minions soak up most of your Paralyzing Cask.
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
* 
Tinker's 
Laser is useful against Outworld Destroyer, as the blind prevents him from landing Arcane Orbs.
Outworld Destroyer
* Any heroes with high intelligence, such as 
Invoker and Pugna.
Witch Doctor
* 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 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 with built-in spell immunity can become immune to all of Outworld Destroyer's spells: 
Lifestealer's 
Rage and 
Juggernaut's 
Blade Fury.
Witch Doctor
* Heroes like 
Slark, Witch Doctor and others also tend to suffer in Ice Blast's heal denial.
Witch Doctor
* Heroes with plenty of summons, such as Broodmother or Nature's Prophet can have their minions soak up most of your Paralyzing Cask.
Witch Doctor
* Generally, any fragile heroes will have a hard time dealing with Undying's tankiness, and even more so if Decay is used on them. Some examples are Crystal Maiden and Witch Doctor.
Witch Doctor
* Heroes with powerful channeling abilities are easily interrupted by Phantom's Embrace: Bane, 
Pudge, Witch Doctor, Crystal Maiden, Enigma.
Witch Doctor
* Channeling heroes will not go well against Warlock, especially those who build 
Black King Bar as Warlock's ultimate ability stun goes through spell immunity. E.g.: Crystal Maiden, Witch Doctor, Enigma, etc.
Witch Doctor
* Heroes with slow movement speeds and small health pools (supports like Crystal Maiden or Witch Doctor) are easy targets for Phoenix. Should they be inflicted by its DOT debuffs, they will be very quickly killed without even getting a chance to fight back.
Witch Doctor
* Low mobility heroes: Heroes with no/little means of traveling fast have difficulty getting to/away from Bounty Hunter due to his slowing Jinada and hastening Track. Few examples of such heroes are: Crystal Maiden, 
Sniper, 
Ursa, Witch Doctor, etc.
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.
Witch Doctor
* Heroes who have channeled abilities can be stunned by Light Strike Array, like Witch Doctor with Death Ward and Bane's 
Fiend's Grip.
Additional:
* 
Light Strike Array cancels out Death Ward from a long distance.
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 silences can negate the majority of Outworld Destroyer's damage output: Death Prophet, Night Stalker, Drow Ranger, Doom .
Witch Doctor
* Death Ward's first target (before it bounces) can evade it, therefore 
Windranger and 
Phantom Assassin are poor choices to use it on.
Witch Doctor
* Fragile supports with low armor are always a good prey, also her Psionic Trap will wear down most attempts to flee with their built-in disables: 
Silencer, Crystal Maiden, 
Warlock, 
Ancient Apparition, 
Grimstroke, Witch Doctor
Outworld Destroyer
* 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
Additional:
* 
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.
Witch Doctor
* Multiple attackers thanks to summoned units or clones: 
Meepo, Witch Doctor, 
Lycan, Enigma, Shadow Shaman
* Heroes that can quickly deal damage to her, regardless of how weak they are, can easily break through her Refraction:
* Multiple attackers thanks to summoned units or clones: Meepo, Witch Doctor, Lycan, Enigma, Shadow Shaman
* Multiple attackers thanks to illusions: 
Phantom Lancer, 
Chaos Knight, 
Naga Siren (bonus for her 
Ensnare). Also despite the visual effects, Templar Assassin does not spill damage against illusions or buildings, so she is not a really good hero to clean up illusions.
* Weak damage but high tick rate or persist in a long time: Slark, 
Gyrocopter, Queen of Pain, Shadow Shaman (
Shackles), 
Jakiro, Pugna, Doom
Witch Doctor
* Low health spellcasters: Lina, Witch Doctor, Tinker, 
Keeper of the Light, all rely heavily on their spells and are fragile heroes. They all also have avoidable spells, allowing Puck to get to them and quickly burst them down.
Outworld Destroyer
* 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.
Additional:
* 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.
Witch Doctor
* Heroes who build Black King Bar as either core or situational item will be able to fight back against Nyx Assassin and freely attack him as Spiked Carapace cannot pierce spell immunity at all: 
Axe, Broodmother, 
Dawnbreaker, Enigma, 
Huskar, Jakiro, 
Legion Commander, Lina, 
Luna, Lycan, 
Slardar, Slark, 
Troll Warlord, Witch Doctor.
Witch Doctor
* 
Lucent Beam interrupts Death Ward from a decent range.
* With Dust of Appearance, 
Eclipse kills Witch Doctor during Death Ward, even through 
Glimmer Cape.
Outworld Destroyer
* Every hero that can withstand or prevent Eclipse at level 7: Juggernaut, 
Riki, 
Clockwerk, Drow Ranger, 
Abaddon, Faceless Void, 
Weaver, Outworld Destroyer.
Witch Doctor
* Beware of placing the Death Ward if 
Chronosphere is off cooldown, as it will cancel the effect and leave Witch Doctor vulnerable if he does not react in time.
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.
Witch Doctor
* Sacred Arrow can be used to interrupt Death Ward from a safe distance, forcing him to cancel it to dodge or get hit.
* Paralyzing Cask is a slow-moving stun, and Mirana can Leap away from her allies to keep it from bouncing.
* Witch Doctor has low health and can easily be killed with an Aghanim's Scepter combo or just when hit with an arrow.
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
* 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.
Witch Doctor
* Paralyzing Cask can save ally from Legion Commander Duel's until she purchases Aghanim's Scepter.
* Voodoo Restoration can heal Witch Doctor allies from Duel's.
* Death Ward can help Witch Doctor allies from winning Duel's, if, he is not a target.
Outworld Destroyer
* 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.
Additional:
* Astral Imprisonment prevents Legion Commander from killing her opponents in Duels.
Witch Doctor
* Paralyzing Cask will repetively bounce between Chen and his converted creeps every single time. This can get even better if Witch Doctor buys Aghanim's Scepter that will allow his Death Ward to bounce between Chen and his converted creeps.
* Paralyzing Cask, Maledict and Death Ward combination will often kill Chen's allies before he can save them with 
Hand of God. And to make things better, Chen has no way to cancel Fiend's Grip on his own, and must rely on outside from {U:Centaur Conqueror} or {U:Mud Golem} under his control.
* 
Voodoo Switcheroo from 
Aghanim's Shard cannot be interrupted by Chen's creeps at all because Witch Doctor is hidden for it's duration.
Additional:
* Paralyzing Cask will repetively bounce between Chen and his converted creeps every single time. This can get even worse if Witch Doctor buys Aghanim's Scepter that will allow his Death Ward to bounce between Chen and his converted creeps.
* Paralyzing Cask, Maledict and Death Ward combination will often kill Chen's allies before he can save them with Hand of God. And to make things worse, Chen has no way to cancel Death Ward on his own, and must rely on outside from {U:Centaur Conqueror} or {U:Mud Golem} under his control.
* Voodoo Switcheroo from Aghanim's Shard cannot be interrupted by Chen's creeps at all because Witch Doctor is hidden for it's duration.
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.
Witch Doctor
* Paralyzing Cask is likely to bounce between him and his bear every single time.
* Lone Druid's lack of mobility makes him vulnerable to Death Ward and Maledict.
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.
Witch Doctor
* Heroes with long-lasting, undispellable debuffs will pinpoint the true Naga Siren: 
Spirit Breaker, 
Bloodseeker, Witch Doctor.
Outworld Destroyer
* Arcane Orb deals pure damage that can bypass Naga Siren's armor, and which can clear her illusions in no time.
* Astral Imprisonment can be used 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.
Witch Doctor
* Maledict cannot be dispelled by Phantasm, and can be used to tag the real Chaos Knight hiding within his illusions.
* If Witch Doctor has an Aghanim's Scepter, Death Ward will bounce between Chaos Knight's illusions, destroying them quickly.
* However, Death Ward is easily interrupted by Chaos Bolt until Witch Doctor buys Glimmer Cape or Black King Bar.
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.
Witch Doctor
* Heroes with abilities or items that can silence or disable Anti-Mage for long periods of time will prevent him from Blinking away: 
Lion, Silencer, Shadow Shaman, Grimstroke, Witch Doctor, Riki, Faceless Void, 
Skywrath Mage, Puck.
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
* 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
* 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
* 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
* 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 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
* 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
* 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
* 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 her taking damage while healing Outworld Destroyer
Witch Doctor
* Voodoo Restoration heals to counter Bloodseeker's 
Thirst.
* 
Rupture is generally useless against Witch Doctor while he is staying on Death Ward.
* Although Witch Doctor needs to be careful as 
Blood Rite can interrupt Death Ward.
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
* Outworld Destroyer's pure damage will mop up Primal Split's units very quickly.
Witch Doctor
* Voodoo Restoration heals to counter damage over time of Viper abilities.
* Viper has no way to cancel Death Ward, even through 
Rod of Atos.
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. Spirit Breakeranity's Eclipse|Outworld Destroyer
* 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
* 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
* 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'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.
Witch Doctor
* Voodoo Restoration heals to counter damage over time of 
Poison Nova and 
Poison Sting.
Witch Doctor
* Paralyzing cask bounces between him and his wolves, keeping him stunned for long amounts of time.
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
* Any heroes with silences can negate the majority of Outworld Destroyer's damage output: Death Prophet, Night Stalker, Drow Ranger, Doom .
Witch Doctor
* Heroes with the ability to heal allies, or those with good defensive abilities: 
Chen, Dazzle, 
Io, Oracle, 
Omniknight, Witch Doctor, Winter Wyvern, Abaddon, etc.
Outworld Destroyer
* Any heroes with low mana pools will die quickly or even instantly to Sanity's Eclipse: Doom, Phantom Assassin, Troll Warlord.
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
* 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.
Outworld Destroyer
* Ursa struggles against heroes with strong (and especially undispellable) disables (Disruptor, Puck, Shadow Demon, Outworld Destroyer and etc).
Witch Doctor
* Heroes with channeling abilities: Enigma, Witch Doctor, Crystal Maiden.
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:
* 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
* 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.
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.
Witch Doctor
* Heroes who rely on channeling abilities can be interrupted in teamfights by Rolling Thunder: Crystal Maiden, Pugna, Witch Doctor
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.
Witch Doctor
* Heroes that have a channeled ability that can be interrupted by Meat Hook: Shadow Shaman, Witch Doctor, Enigma, Bane.
Additional:
* 
Meat Hook interrupts Death Ward from a decent range, even through Black King Bar & Glimmer Cape.
* Pudge can survive the damage from Maledict because of his 
Flesh Heap stacks.
* However the damage-over-time from 
Rot is counteracted by Voodoo Restoration.
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
* 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.
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.
Witch Doctor
* Heroes with channeled abilities can be interrupted by a long-range Fissure: Crystal Maiden, Witch Doctor, Bane, Pugna, Pudge.
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.
Witch Doctor
* Heroes that have small health pools and little to no escape mechanisms are even easier prey for Necrophos. Ghost Shroud's slow will allow him to catch him with them, and get nuked down with his abilities, even preventing retaliation due to Reaper's Scythe's stun. Such heroes include Crystal Maiden, Witch Doctor, Warlock or Shadow Fiend.
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
Witch Doctor
* Heroes with long channeling abilities like Witch Doctor are easy targets for Kunkka to interrupt in team fights.
Additional:
* 
Torrent can cancel Death Ward from a far distance.
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.
Witch Doctor
* Witch Doctor's Maledict burst damage can be prevented by Sunder if timed correctly. But it can kill Terrorblade if he has no target to be Sundered with, especially in the early game.
* Death Ward deals physical damage, and Terrorblade's high armor can help him survive against Death Ward. However, Terrorblade has no disable in his skillset at all, and he cannot stop Witch Doctor from channeling Death Ward to maximum. And if Witch Doctor owns Aghanim's Scepter, attacks from Death Ward will be able to bounce around and wipe out Terrorblade's illusions and his team.
* Terrorblade must be careful as Paralyzing Cask is commonly tricky to dodge for him due to his reliance on illusions.
Witch Doctor
* Heroes who have channeling abilities because Terrorblade has no disables to cancel them at all besides 
Terror Wave from Aghanim's Scepter, and he does not like buying disabling items at all: Enigma's Black Hole, Witch Doctor's Death Ward, Shadow Shaman's Shackles, Lion's 
Mana Drain, Bane's Fiend's Grip, Pudge's 
Dismember, Crystal Maiden's 
Freezing Field, Pugna's 
Life Drain, Dawnbreaker's 
Solar Guardian, and Naga Siren's 
Reel In from Aghanim's Scepter.
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.
Witch Doctor
* Death Ward does little damage against Dragon Knight's armor, and Dragon Knight's high health regeneration minimizes damage from Maledict.
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.
Witch Doctor
* Death Ward's first target (before it bounces) can evade it, therefore Windranger and Phantom Assassin are poor choices to use it on.
Outworld Destroyer
* Any heroes with low mana pools will die quickly or even instantly to Sanity's Eclipse: Doom, Phantom Assassin, Troll Warlord.
Witch Doctor
* Morphling can 
Attribute Shift to strength after being hit by Maledict. Since Maledict deals its damage based on the difference between HP on cast and HP after two seconds, odds are Morphling will have more HP than when Maledict was cast, thus resulting in no damage.
* On the upside, players prone to panicked reactions may Morph to agility, making Maledict even more efficient than intended.
* 
Adaptive Strike (Strength) can interrupt Death Ward at a decent range.
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.
Witch Doctor
* 
Kraken Shell dispels the stun from Paralyzing Cask. However, it does not dispel the damage from Maledict.
* Once Witch Doctor first uses his Death Ward in team fights, Tidehunter can simply cancel it with 
Ravage, turning the tables against him, especially if Witch Doctor does not have a Black King Bar.
* As a precaution, Witch Doctor should let Tidehunter use Ravage first before channeling Death Ward to turn a team fight in his favor.
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.
Witch Doctor
* Paralyzing Cask's short stun rarely prevents Monkey King from ambushing Witch Doctor.
* Death Ward's long channel is easily interrupted by Boundless Strike.
Witch Doctor
* Another hero that should not leave a special circle for his ultimate. The only thing to be afraid is 
Boundless Strike.
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.
Witch Doctor
* Death Ward with Aghanim's Scepter makes quick work of the spawned illusions from Disruption.
* However, it can be cancelled by Disruption until Witch Doctor buys 
Linken's Sphere or Black King Bar.
* All of Witch Doctor's abilities are active, making Demonic Purge break from Aghanim's Scepter useless.
* Voodoo Restoration can out-heal the damage from Shadow Demon's abilities.
* An attempt to save an ally using Disruption can easily become a perfect setup for a Maledict or Paralyzing Cask for the enemy.
Witch Doctor
* Heroes who cannot escape from Trample early might be easy first blood. Heroes like Witch Doctor and Omniknight should play very cautiously alone...
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.
Witch Doctor
* 
Guardian Angel protects allies from Death Ward's physical damage.
* 
Purification and 
Heavenly Grace will most likely save teammates from dying to Maledict.
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.
Witch Doctor
* Death Ward can be easily canceled by Jakiro, or even turned against him with Macropyre, due to it's attack range being smaller then Jakiro's cast range. And Crystal Maiden, his Scepter does not allow him to move while using it. Voodoo Switcheroo is even easier to land Jakiro's Macropyro/Ice Path combo. And unlike Crystal Maiden, Witch Doctor's Aghanim's Scepter upgraded Death Ward does not allow him to move while using it.
* While Maledict can be quite effective on Jakiro, along with repetitive stuns from Paralyzing Cask, it is very difficult to get a strong Maledict on him. Although Witch Doctor's Paralizying Cask, Maledict and Death Ward combo will still quickly eliminate Jakiro.
* On the other hand. Voodoo Restoration will partly protect his allies from Jakiro spells, as it heals based on their Max Health once he gets his Talent (Level 25). Before then though, it won't make a dent in the damage Jakiro deals.
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
Witch Doctor
* Wraithfire Blast cancels Death Ward in decent range.
* Death Ward is meaningless while Reincarnation is off cooldown.
* Vampiric Aura can out-heal the {tooltip:DoT|Damage over Time} from Maledict.
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.
Witch Doctor
* Like any hero with a channeled spell,
Last Word is a counter to it. 
Global Silence goes through spell immunity and prevents Witch Doctor from casting his spells.
*
Outworld Destroyer
* Silencer's intelligence steal will heavily reduce Outworld Destroyer's damage output, especially if Destroyer dies a lot near Silencer and loses intelligence permanently.
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.
* Global Silence and Last Word will render Outworld Destroyer helpless unless he has an item/ally to dispel silence.
Additional:
* Silencer's
*
