* Heroes who can stun multiple units at once: Dark Willow, Spirit Breaker, Slardar, Invoker, and Tidehunter.

* Void Spirit can dodge Earthbind with Dissimilate and Astral Step, giving him a good chance to escape. If he gets caught anyways, Resonant Pulse allows him to retaliate.

* Heroes who can provide True Sight are always credible threats: Slardar, Bounty Hunter, especially Zeus since his Lightning Bolt provides True Sight without the need to detect her beforehand to apply the debuff. So even a late-coming Zeus can easily scout a large area to reveal her, and she cannot purge herself from his sight with the dispel talent.

* While Slardar has Guardian's Sprint activated, Powershot cannot slow him and is easier to avoid.
* Slithereen Crush and Bash of the Deep help Slardar put Windranger in place, even when she uses Windrun to escape.
* Corrosive Haze from Slardar is very effective against Windranger's already low armor. This becomes even worse if she has Aghanim's Scepter-upgraded Windrun, because it also reveals her position and allowing his allies to use their abilities on Windranger.
* Note that the invisibility provided by Aghanim's Scepter-upgraded Windrun is not broken upon attacking, casting abilities or using items, so it's vital to cast Corrosive Haze beforehand.

* Void Spirit deals entirely magical damage in the early game, ignoring her evasion from Windrun.
* A Void Spirit with fast reaction time can use Dissimilate or Astral Step to dodge Powershot.

* A Void Spirit with fast reaction time can use Dissimilate or Astral Step to dodge Powershot.

* Bounty Hunter and Slardar both have ultimates (Corrosive Haze and Track) that reveal Invoker through Ghost Walk.

* A good choice against Invoker, as it has some advantage with the help of abilities.
* With the Dissimilate, Voidspirit can evade Invoker's skills, going to another world where he does not receive damage. The same ability to run away or attack quickly.
* Astral Step moves quickly from point to point, which also reduces the Invoker's probability that he will hit him with skills and cause at least some damage.
Additional:
* A good choice against Invoker, as it has some advantage with the help of abilities.
* With the Dissimilate, Voidspirit can evade Invoker's skills, like Chaos Meteor or E.M.P., going to another world where he does not receive damage. The same ability to run away or attack quickly.
* Astral Step moves quickly from point to point, which also reduces the Invoker's probability that he will hit him with skills and cause at least some damage.

* Slardar deals entirely physical damage. He does not have to worry about Counterspell.
* Slithereen Crush and Bash of the Deep prevent Anti-Mage from using Blink, the latter even if Anti-Mage activates Black King Bar.
* Corrosive Haze allows allies to take down Anti-Mage before he has a chance to Blink, and maintains vision over him even if he does Blink away.
Additional:
* Slithereen Crush and Bash of the Deep deals physical damage, bypassing the magic resistance bonus from Counterspell
* Corrosize Haze significantly increases the damage dealt against Anti-Mage, and makes it harder for him to flee with Blink, although Anti-mage can block its casting with with Counterspell

* 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.

* Slardar's Slithereen Crush allows him to stun Spectre and illusions, and Corrosive Haze prevents her from juking with Spectral Dagger.

* Void Spirit is strong against heroes who cannot deal with his rotations due to his mobility. Such heroes include Spectre, Gyrocopter, Morphling, and Chen.

* Void Spirit can greatly pressure Morphling's farm, which is very bad for a hero who needs a large amount of space.
* Waveform does not provide better mobility than Astral Step.
* If Morphling shifted all of his strength to agility, he can be bursted down by Void Spirit before he can react.
* Doing an Ethereal Blade combo on Void Spirit is incredibly difficult, as Dissimilate and Astral Step can allow him to escape or dodge the projectile.

* Keeping Void Spirit inside Wukong's Command is a very tricky task, especially in the early and mid game. In addition, if Monkey King is in a bad position, a well placed Aether Remnant can easily pull him out of the ring.
* Getting stacks of Jingu Mastery can be difficult when attacking Void Spirit.

* Guardian Sprint allows Slardar to outrun Bristleback, even when slowed by Viscous Nasal Goo.
* Corrosive Haze's armor reduction makes Bristleback much less tanky.

* Void Spirit can easily dodge Gyrocopter's {Ability ID:Homing Missile|gyrocopter} with the help of Dissimilate.
* Void Spirit can partly dodge Call Down via Dissimilate or move out of its range with Astral Step.
* Gyrocopter has no escape abilities, which benefits Void Spirit's high mobility.

* 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 and Bash of the Deep will make short work of Huskar's low armor, even if Slardar is alone.

* Guardian Sprint allows Slardar to avoid Meat Hook.
Additional:
* While Slardar has Guardian Sprint activated, Rot cannot slow him and Meat Hook is easier to avoid.
* Slithereen Crush allows Slardar to interrupt Dismember at close range (when Slardar is not a target).
* Corrosive Haze reveals Pudge's location, making it very difficult for him to land hooks from the fog.

* Corrosive Haze works much like Track, giving the enemy team vision over Riki. While it doesn't give a movement speed or gold bonus, it instead can melt Riki's armor and Slardar can use Guardian Sprint to catch up to him.
* Slardar's Aghanim's Shard, causes Slithereen Crush to apply Corrosive Haze even if Slardar does not have vision over him.
Additional:
* Corrosive Haze makes Riki completely vulnerable to Slardar and his allies, as Riki has no easy way of dispelling it.
* Slardar's physical damage with Slithereen Crush and Bash of the Deep amplified by Corrosive Haze can easily kill Riki.

* Corrosive Haze hinders Nyx Assassin's ganking attempts with Vendetta, as well as reducing his armor and make him very vulnerable due to his low health pool.
* Guardian Sprint allows Slardar to catch up with Nyx Asssassin and finish him off if he has vision over him.

* Dissimilate and Astral Step allow Void Spirit to quickly escape from Cold Feet.
* Void Spirit deals both magical and physical damage, which makes Ancient Apparition an easy target to ambush.
* If Void Spirit purchases Aghanim's Scepter, the silence provided by Resonant Pulse can disrupt Ancient Apparition during fights, as he is entirely reliant upon spells to contribute.

* Weaver relies on Shukuchi to escape and kite enemy heroes. Slardar's Corrosive Haze lowers armor and reveals Weaver, who is already a very frail target.
* Weaver usually builds Linken's Sphere, Corrosive Haze can be used to pop the spell block, additionally the level 25 undispellable talent will prevent Weaver from removing Corrosive Haze with Time Lapse, allowing allied heroes to use their abilities on Weaver.
Additional:
* Corrosive Haze lowers armor and reveals Weaver during Shukuchi, who is already a frail target. In addition, Weaver usually builds Linken's Sphere, and Corrosive Haze can be used to "pop" the spell block. His level 25 talent can also make Corrosive Haze undispellable by Time Lapse, which puts Weaver in an even worse situation.
* Guardian Sprint can dodge Weaver's bugs with the movement speed bonus.

* Corrosive Haze followed by Slithereen Crush takes advantage of Alchemist's main weakness, being physical damage before he has the change to improve his surviability with items.
* Bash of the Deep will deal lots of damage during the laning phase.

* Slardar can reveal Clinkz with Corrosive Haze and make him easy to kill, and his Bash of the Deep also hits hard against Clinkz's naturally low health pool.
* Slardar's Guardian Sprint can catch up with Clinkz's Skeleton Walk.
* The stun and slow from Slardar's Slithereen Crush can hold Clinkz in place.
Additional:
* Clinkz survivability depends entirely on Skeleton Walk. Corrosive Haze not only makes its invisibility useless, but also makes Clinkz even more vulnerable to physical damage.

* Corrosive Haze will reveal Treant Protector even when he is under the effects of Nature's Guise.

* 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.

* Heroes with considerable mobility can easily escape from a rolling Pangolier: Anti-Mage, Queen of Pain, Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, moreover, if a player is familiar with how Rolling Thunder works, they can adjust their movement to avoid it entirely and of course outplay the Pangolier player.

* Heroes with spells that negate invisibility such as Bounty Hunter, Zeus and Slardar prevent her from saving her allies with Moonlight Shadow.

* 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.

* Heroes who can provide True Sight or semi-reveal enemy heroes as Nature's Prophet is prone to buying Shadow Blade: Bounty Hunter, Slardar, Spectre, Zeus, Spirit Breaker.

* Crystal Maiden's already low armor and easily interruptible ultimate, Freezing Field can make Slardar her worst nightmare. Crystal Maiden also often builds Glimmer Cape which is revealed by Corrosive Haze.

* 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.

* Void Spirit's AoE damage can make short work of Broodmother's spiderlings
* Even if she is within the range of her spiderwebs from Spin Web Broodmother cannot escape Void Spirit's mobility.
* However, Spinner's Snare from Aghanim's Scepter can be very hazardous for Void Spirit, as it allows Broodmother to create invisible lines on her webs from Spin Web that will root Void Spirit, deal damage over time to him and reveal him if he unwittingly steps on them, disrupting Void Spirit's ganking or escaping attempts with Dissimilate and Astral Step while also alerting Broodmother on his attempts to ambush her and her allies.

* With armor items like Solar Crest or Assault Cuirass combined with Bash of the Deep, Slardar can easily tank the Duel, If not dueled himself, he can drop Legion Commander's armor during duel and/or buff his teammate and save them, leaving her only the choice of dueling supports which can also be saved with fast Blink into Slithereen Crush.

* Slardar is one of the few meele heroes who can lane against Ursa in the early game, out harassing him with Bash of the Deep, and running away from a bad engagement with Guardian Sprint

* Terrorblade has no disables to prevent Void Spirit from escaping.

* Slardar can chase Dragon Knight down with Guardian Sprint and stun him with both Slithereen Crush and his passive Bash of the Deep. He can also use Corrosive Haze to whittle Dragon Knight's armor.

* Shadow Fiend, a normal Shadow Blade builder often relies on its invisibility to escape fights. Corrosive Haze reveals Shadow Fiend and also weakens his already low armor.

* Corrosive Haze provides True Sight on its target, exposing Bounty Hunter's position regardless of Shadow Walk.
* Guardian Sprint gives a very high movement speed bonus, allowing him to chase Bounty Hunter even if Slardar is tracked.
