Mars
[wiki] rating: 2.0 (winrate: 48% pickrate: 16%)Omniknight
[wiki] rating: 2.0 (winrate: 47% pickrate: 1%)Slark
* Slark's dependence on Pounce and close range makes him very easy to hit with 
Purification.
* Slark's damage, even with a high count of Essence Shift, is easily negated by Omniknight's heals and 
Guardian Angel.
Spectre
* Global Guardian Angel will protect his allies from Spectre's 
Haunt, both when they are alone and in teamfights.
* Purification is a major problem for melee enemies, Spectre included, since they must be next to an enemy in order to attack. The AoE damage also allows Spectre to be singled out from her illusions.
* 
Degen Aura will prevent Spectre from chasing Omniknight, further exacerbated by her terrible mobility outside Haunt.
Viper
[wiki] rating: 2.0 (winrate: 47% pickrate: 6%)Spectre
* Nethertoxin disables 
Desolate and 
Dispersion, leaving Spectre with far less damage output and damage mitigation in engagements.
* Spectre is one of the weakest heroes at early levels. Viper can stifle her farm with early fights before Spectre purchases any major items.
Additional:
* 
Nethertoxin disable passives, negating Spectre's damage and survivability by removing both Dispersion and Desolate.
* Due to Haunt and 
Radiance's burn, Spectre is heavily susceptible to being persistently slowed and damaged by 
Corrosive Skin without even directly attacking Viper.
* 
Poison Attack and 
Viper Strike further slow Spectre's movement speed to a crawl, while his improved magic resistance means he can easily shrug off Radiance's burn.
Slark
* Nethertoxin negates 
Essence Shift and the regeneration aspect of 
Shadow Dance.
* 
Dark Pact doesn't mean a lot against Viper's ubiquitous slows.
* Viper becomes a relevant presence in team fights before Slark can procure his standard items (e.g. 
Shadow Blade).
Night Stalker
[wiki] rating: 1.6 (winrate: 52% pickrate: 5%)Spectre
* Heroes that have a weak laning stage: 
Spectre, 
Nyx Assassin, 
Clockwerk, 
Spirit Breaker, 
Omniknight, 
Pudge.
Slark
* With Dark Ascension he can keep vision on Slark, disabling his Shadow Dance regeneration. Slark is also too weak to seriously threaten Night Stalker in lane.
Disruptor
[wiki] rating: 1.6 (winrate: 49% pickrate: 9%)Spectre
* 
Disruptor can control where she goes with 
Kinetic Field and 
Glimpse. 
Static Storm shuts her down in teamfights.
Slark
* Thunder Strike provides vision on him while Slark is invisible.
* Glimpse's range at lvl 3-4 is more than enough to pull him back to a favorable position for your team to group up and kill him.
* Even though he is capable of picking you off and deal enough damage to kill you, Slark will be literally sticking his neck out, since jumping on Disruptor means being on his battleground.
* AoE silence and the ability to mute Black King Bar is deadly to Slark at all stages of the game.
Additional:
* Static Storm and Kinetic Field locks down Slark, as he cannot use Dark Pact to dispel any disables, or Pounce out while silenced.
* Glimpse puts an end to any attempts at ganking Disruptor or his allies, and also negates Slark's mobility by bringing him back into the fight if he tries to escape with Pounce.
Meepo
[wiki] rating: 1.6 (winrate: 45% pickrate: 1%)Slark
* 
Slark's Dark Pact and Pounce can deny only one Earthbind and Poof can penetrate Shadow Dance if he doesn't build Black King Bar.
Additional:
* 
Earthbind and 
Poof will still hit Slark in Shadow Dance.
* Dark Pact can only remove one Earthbind.
* 
Ransack will still affect Slark, even if he has a 
Black King Bar.
Spectre
* Poof combined with Earthbind can be used to easily lockdown and burst Spectre down.
* As Meepo's playstyle is often to come online early to mid game and take over the whole game, Meepo will often be much further ahead of Spectre in farming.
* Meepo's global map presence allows him to effectively hunt for Spectre and disrupt her farm.
* Spectre has no strong AOE abilities or way to control or lock down Meepo.
Doom
[wiki] rating: 1.6 (winrate: 44% pickrate: 2%)Slark
* Heroes with silencing abilities can be particularly deadly when Slark is trying to escape: 
Silencer, 
Death Prophet, 
Puck, 
Doom
Spectre
* 
Infernal Blade's damage is calculated by percentage of max health. Since Spectre is usually tanky, it will hurt her more than most normal attacks.
* 
Doom can entirely disable Spectre from a teamfight. If upgraded with 
Aghanim's Scepter, it will disable her passive skills which is she relies on, crippling her.
Additional:
* Infernal Blade's damage is calculated by percentage of maximum health, meaning that it will hurt Spectre more than most normal attacks, negating some of her tankiness.
* Doom can pick up several different abilities from neutral creeps using 
Devour, some of which can be annoying to Spectre.
* Mud Golem, Dark Troll Summoner, Harpy Stormcrafter, Satyr Mindstealer or Satyr Tormenter are good examples.
* Doom makes Spectre less disruptive. Combined with Aghanim's Scepter, it will disable Spectre passive skills, reducing her potential in teamfights.
Jakiro
[wiki] rating: 1.2 (winrate: 50% pickrate: 9%)Spectre
* Jakiro's early pushing ability from Liquid Fire makes Jakiro very strong against heroes, that take a long time to get online: 
Morphling, 
Naga Siren, Spectre.
Slark
* Heroes with AoE abilities will hit Slark in Shadow Dance: 
Lina, 
Jakiro, 
Underlord, 
Leshrac, 
Dark Seer, 
Earthshaker, 
Timbersaw, 
Crystal Maiden
Slardar
[wiki] rating: 1.2 (winrate: 50% pickrate: 5%)Spectre
* 
Slardar's 
Slithereen Crush allows him to stun Spectre and illusions, and 
Corrosive Haze prevents her from juking with 
Spectral Dagger.
Slark
* Slardar's level 25 talent makes Corrosive Haze undispellable, thus providing his allies a vision to Slark.
Visage
[wiki] rating: 1.0 (winrate: 54% pickrate: 1%)Spectre
* Familiars will be able to chase Spectre through the trees when she uses Spectral Dagger, while Visage can keep blasting her with Soul Assumption.
* Desolate will almost never proc because Visage will always have nearby Familiars.
Pugna
[wiki] rating: 1.0 (winrate: 53% pickrate: 4%)Spectre
* 
Nether Blast is one of the best tower pushing abilities in the game, with a low cooldown. A competent Pugna will (at the very least) destroy tier 2 towers and make space for his team before Spectre can finally come online.
* Spectre's spells, while not spammable, have a fairly high mana cost, so 
Nether Ward can be fairly damaging to Spectre early game. The mana degen will also dampen Spectre's early game power significantly.
* Once Pugna gets Aghanim's Scepter, he can spam 
Life Drain on any illusion Spectre summons, whether it'd be from Haunt, 
Manta Style, or some other means.
* In addition, Pugna can disable Spectre's Desolate ability (although its damage is pure, it requires physical attacks) with his 
Decrepify ability, leaving Spectre only with Spectral Dagger.
Chaos Knight
[wiki] rating: 1.0 (winrate: 52% pickrate: 3%)Slark
* Dark Pact is minimally effective against Phantasm illusions, and Slark lacks area damage otherwise.
* 
Pounce can be counteracted by Reality Rift.
* Slark is naturally frail and dies quickly to Chaos Knight's burst damage before he can build Essence Shift stacks.
* Be aware, however, that Shadow Dance can make Slark hard to kill as he can't be targeted during its duration.
Additional:
* 
Phantasms have enough health to survive Dark Pact, and Slark has no other source of AoE damage to deal with them.
Phantom Lancer
[wiki] rating: 1.0 (winrate: 51% pickrate: 10%)Slark
* Slark has no sustained AoE to fight off Phantom Lancer's illusions as they continually spawn.
* Spirit Lance can give vision of Slark by spawning an illusion, making it harder for him to juke and gain the passive bonus from Shadow Dance.
* 
Phantom Rush helps Phantom Lancer chase down Slark if he tries to escape with Pounce.
Additional:
* Slark has no sustained AoE to deal with Phantom Lancer's many illusions.
* 
Doppelganger lets Phantom Lancer dodge Dark Pact and Pounce, and partially wastes the duration of Shadow Dance.
* 
Spirit Lance can give vision of Slark via spawning an illusion, making it harder for him to juke and gain the passive bonus from Shadow Dance.
* Phantom Rush helps Phantom Lancer chase down Slark when he jumps away with Pounce.
Outworld Destroyer
[wiki] rating: 1.0 (winrate: 51% pickrate: 13%)Slark
* 
Arcane Orb deals pure damage, which ignores armor granted from permanent agility stacks.
* 
Astral Imprisonment can disrupt any Pounce attempt by banishing the leashed ally.
* Slark's low intelligence and therefore mana pool makes him more susceptible to 
Sanity's Eclipse.
Bloodseeker
[wiki] rating: 1.0 (winrate: 51% pickrate: 4%)Slark
* Thirst prevents Slark from healing with Shadow Dance.
* Rupture will deal damage during Pounce.
* Dark Pact cannot dispel Rupture, preventing Slark from escaping ganks.
Additional:
* 
Thirst makes Slark visible while at low health, canceling out Shadow Dance's passive. For this reason, Bloodseeker is usually considered the hardest counter to Slark.
* 
Rupture cannot be dispelled by Dark Pact, and using Pounce while affected by it will cause Slark to take damage.
Undying
[wiki] rating: 1.0 (winrate: 50% pickrate: 4%)Spectre
* Spectre must chase for kills and relies on movement speed for mobility in fights, and has no way to counter the 
Tombstone zombies.
* The potency of 
Soul Rip can be increased from nearby illusions from Haunt.
* 
Decay will shut down Spectre during the laning phase by effectively cutting down her initial health pool.
Additional:
* Spectre must chase for kills and relies on movement speed for mobility in fights, and has no way to counter the Tombstone zombies.
* The potency of Soul Rip can be increased from nearby illusions, so Undying can use Haunt against Spectre.
* Early game Decay will make Spectre easy to shut down in lane.
Elder Titan
[wiki] rating: 1.0 (winrate: 49% pickrate: 1%)Slark
* Natural Order aura prevents Slark from gaining armor from the agility stolen with Essence Shift.
* Echo Stomp and Earth Splitter can hit Slark through his Shadow Dance ultimate.
* Slark's stats gain is relatively low compared to most agility carries making him quite squishy without his agility-based armor.
Centaur Warrunner
[wiki] rating: 1.0 (winrate: 48% pickrate: 3%)Slark
* Both 
Hoof Stomp and 
Double Edge can hit Slark during Shadow Dance, the latter requiring a unit nearby for the ability to be cast on.
* Slark has very low health in the early game, making him susceptible to the burst from Double Edge.
Shadow Demon
[wiki] rating: 1.0 (winrate: 47% pickrate: 2%)Spectre
* Her illusions with Desolate are very valuable, especially when they are usually paired with Radiance. Unlike blink or force movement, Spectral Dagger's escaping mechanic requires manual movement, and therefore Demonic Purge can hold her back really hard and allow your allies to finish her off.
* If she tries to kill you or any key ally with Haunt at any point of the game, remember to not panic and always use Disruption on the illusion, whether it is fake or the real Spectre herself. When the situation calls, Demonic Purge can save a second victim from a haunting Spectre.
* When upgraded by Aghanim's Scepter, Demonic Purge can remove Spectre from a fight by disabling Desolate and Dispersion, negating her damage and tankiness respectively.
Slark
* Heroes with Break abilities will prevent Slark from regenerating and gaining Essence Shift stacks: 
Viper, 
Shadow Demon etc.
Slark
* Heroes who can dispel will be able to remove Shadow Poison before Shadow Demon can build up a big stack, or remove Soul Catcher's debuff to instantly bring the health of affected heroes back to a considerable amount: 
Abaddon, Slark, 
Legion Commander, 
Oracle.
Terrorblade
[wiki] rating: 1.0 (winrate: 46% pickrate: 4%)Spectre
* If Terrorblade's health gets low enough, Terrorblade's 
Sunder can be used to completely deplete Spectre's health pool without any consequences from Dispersion.
* Terrorblade is one of the few late game heroes that can stand toe to toe and man fight Spectre. Not all is lost if the game goes late when Terrorblade is on your team against Spectre.
Shadow Fiend
[wiki] rating: 1.0 (winrate: 46% pickrate: 18%)Slark
* Shadow Dance does not protect Slark from Shadow Fiend's AoE spells.
Tiny
[wiki] rating: 1.0 (winrate: 45% pickrate: 5%)Slark
* A 
Toss plus 
Avalanche combination deals heavy damage to Slark in the early game, making Tiny a very dangerous target to gank.
Kunkka
[wiki] rating: 1.0 (winrate: 44% pickrate: 3%)Spectre
* Spectre can't escape with Spectral Dagger under X Marks the Spot.
* Kunkka can dominate Spectre's lane using Tidebringer and gain an advantage.
* Ghostship helps your team soak up damage from Haunt.
Abaddon
[wiki] rating: 0.6 (winrate: 52% pickrate: 5%)Slark
* Heroes that can deny Slark early kills will prevent him from snowballing: 
Dazzle, Abaddon
Hoodwink
[wiki] rating: 0.6 (winrate: 52% pickrate: 15%)Spectre
* Durable heroes relied a lot on their main passive effects and items' effects such as 
Bristleback, Underlord, Spectre and 
Dragon Knight can be disabled easily with 
Sharpshooter's break, reducing their potential in teamfights.
Death Prophet
[wiki] rating: 0.6 (winrate: 51% pickrate: 10%)Slark
* Heroes with silencing abilities can be particularly deadly when Slark is trying to escape: Silencer, Death Prophet, Puck, Doom
Dark Seer
[wiki] rating: 0.6 (winrate: 51% pickrate: 3%)Slark
* Heroes with AoE abilities will hit Slark in Shadow Dance: Lina, Jakiro, Underlord, Leshrac, Dark Seer, Earthshaker, Timbersaw, Crystal Maiden
Spectre
* Dark Seer can pull together Spectre's illusions with 
Vacuum, and 
Wall of Replica creates an illusion of Spectre that deals massive damage.
Slark
* Dark Seer relies on Surge for most of his mobility, so he's not very vulnerable to slows, but much more to root effects and walls or pseudo-walls such as Disruptor's Kinetic Field or Slark's Pounce.
Underlord
[wiki] rating: 0.6 (winrate: 51% pickrate: 7%)Slark
* Heroes with AoE abilities will hit Slark in Shadow Dance: Lina, Jakiro, Underlord, Leshrac, Dark Seer, Earthshaker, Timbersaw, Crystal Maiden
Weaver
[wiki] rating: 0.6 (winrate: 51% pickrate: 13%)Spectre
* Heroes with good escapes can usually outmaneuver and escape from Spectre: Slark, 
Clinkz, 
Weaver
Leshrac
[wiki] rating: 0.6 (winrate: 51% pickrate: 3%)Slark
* Heroes with AoE abilities will hit Slark in Shadow Dance: Lina, Jakiro, Underlord, Leshrac, Dark Seer, Earthshaker, Timbersaw, Crystal Maiden
Lion
[wiki] rating: 0.6 (winrate: 50% pickrate: 17%)Spectre
* 
Hex and 
Mana Drain can be used to immediately destroy Spectre's illusion when she Haunts. A fast fingered Lion can protect himself and a teammate.
* Hex and 
Earth Spike are good lockdown spells to control and kill Spectre, especially if she doesn't buy defensive items like 
Linken's Sphere and Black King Bar.
* 
Finger of Death can be used to burst down Spectre when she is low on life as she has very poor magic resistance.
Slark
* Heroes with heavy magical nukes will take advantage of Slark's poor HP or force him to use Shadow Dance early: Lina, 
Lion, 
Zeus
Slark
* Pounce allows Slark to close in on Lion and prevent him from escaping.
* Lion's fragile health pool makes him easy prey for Slark's high burst damage through Pounce, Dark Pact and right-clicks.
* Shadow Dance prevents Lion from casting Hex, Mana Drain, or Finger of Death on Slark.
* Dark Pact allows Slark to dispel any of Lion's disables.
Void Spirit
[wiki] rating: 0.6 (winrate: 50% pickrate: 13%)Spectre
* Void Spirit is strong against heroes who cannot deal with his rotations due to his mobility. Such heroes include Spectre, 
Gyrocopter, Morphling, and 
Chen.
Crystal Maiden
[wiki] rating: 0.6 (winrate: 49% pickrate: 14%)Slark
* Though Slark's large damage output is most certainly a concern for the squishy Crystal Maiden, she does perform fairly well against him when coupled with aid from her team.
* Slark has no innate way to cancel Freezing Field, but the common purchase of 
Skull Basher does make Slark a substantially greater threat to Crystal Maiden as the game progresses.
* Freezing Field can still hit Slark while he is under the effect of Shadow Dance, and for the early and mid game, the damage output of Crystal Maiden's ultimate outscales Slark's passive regeneration, making a quick use of Freezing Field as soon as Slark uses Shadow Dance a great way to combat him.
* Crystal Maiden's Frostbite and Crystal Nova are helpful in disabling and slowing the slippery Slark so he can be killed by her teammates.
Spectre
* Heroes the make heavy use of illusions, like 
Chaos Knight, 
Phantom Lancer, or Spectre can suffer from Crystal Maiden, as Freezing Field can quickly kill off the entire horde if not stopped.
Spectre
* As Crystal Maiden is squishy with very bad movement speed, Spectre can easily stay on Crystal Maiden with Haunt and Spectral Dagger.
* Late game, with enough farm, Spectre can withstand an entire 
Freezing Field, possibly even causing Crystal Maiden to kill herself from Dispersion.
Anti-Mage
[wiki] rating: 0.6 (winrate: 49% pickrate: 13%)Spectre
* Spectre cannot chase down Anti-Mage with Spectral Dagger because of Blink, though it still grants her team vision over him.
* Counterspell reduces much of the damage from Dispersion and Spectre's Radiance.
* Anti-Mage usually builds a Manta Style, preventing Spectre from dealing any Desolate damage to him once he summons his illusions.
Additional:
* Spectre has no way to prevent 
Blink, for escape or initiation. Anti-Mage can easily pick off enemy supports and Spectre cannot do anything about it.
* 
Mana Break burns through Spectre's low mana pool.
* Manta Style's illusions prevent Desolate's damage.
* Even though Anti-Mage is outcarried by Spectre in the later stages of the game, a competent Anti-Mage with a 
Battle Fury can easily outfarm and get ahead of Spectre before she can come online.
Slark
* Heroes who build mana boosting items but have low mana regeneration are especially vulnerable against Mana Break and Mana Void: Timbersaw, Slark, 
Shadow Fiend, Clinkz, Bristleback Nyx Assassin, 
Magnus
Slark
* Pounce prevents Anti-Mage from using Blink, and lets him disengage from Anti-Mage if needed.
* Essence Shift allows Slark to permanently steal agility from Anti-Mage.
* Shadow Dance stops Anti-Mage from being able to fight back in a slippery situation.
Storm Spirit
[wiki] rating: 0.6 (winrate: 49% pickrate: 12%)Slark
* Heroes that rely on their high mobility such as 
Queen of Pain, Slark and Weaver can be constantly engaged against due to your excellent ability to chase over any terrain. Make sure you carry true sight items (such as 
Dust of Appearance or 
Gem of True Sight) for invisible heroes that could potentially escape your clutches.
Spectre
* Ball Lightning is the ultimate counter to Spectre's entire toolkit. With this ability, he can score easy kills on Spectre without her having any means of escape early game, kite her and her Haunt illusions when it's later in the game due to her having no form of pseudo-blinks. Furthermore, it is very difficult for Spectre to deal any substantial damage against Storm Spirit with Desolate, and without both a Manta Style and a 
Diffusal Blade he will always remain on the move. Also, Ball Lightning grants invulnerability, and as Storm Spirit likes to spam that ability, he can mitigate the damage done from Dispersion and Radiance.
Additional:
* Storm Spirit can exploit every one of Spectre's weaknesses, and thus is one of the best counters against her.
* Spectre has to be in melee range to deal damage, making her likely to trigger 
Static Remnants and susceptible to being kited by 
Overload procs.
* 
Electric Vortex can lock Spectre down as she doesn't like to build Black King Bar.
* 
Ball Lightning gives Storm Spirit multiple advantages:
* Spectre cannot evade Storm Spirit, as Ball Lightning is superior to Spectral Dagger in terms of mobility.
* Storm Spirit can kite her and her Haunt illusions when it's later in the game due to her having no form of pseudo-blinks (Reality is far inferior to Ball Lightning).
* It is very difficult for Spectre to deal any substantial damage against Storm Spirit with Desolate. Ball Lightning grants invulnerability and can mitigate damage done from Dispersion and Radiance.
* To mitigate this, Spectre needs a team with hard disable to take Storm Spirit out.
Slark
* Pounce's leash prevents Storm Spirit from using Ball Lightning, making it hard for Storm Spirit to escape a gank from Slark.
* Dark Pact can dispel 
Orchid Malevolence's Soul Burn.
Lycan
[wiki] rating: 0.4 (winrate: 54% pickrate: 3%)Spectre
* The movement speed granted from 
Shapeshift means that Spectre has no way to punish Lycan if he wants to splitpush or pick off supports. Furthermore, he will kite Haunt and cannot be slowed by Spectral Dagger.
* As Lycan typically has 
Summon Wolves out and builds 
Necronomicon, very rarely will he be damaged by Desolate if he does manage to get into a fight against her.
* Lycan is often part of an early game push strategy which is often the best counter to Spectre because she needs a lot of time and space to come online as a late game carry.
Slark
* 
Lycan cannot escape from a Pounce even if he uses Shapeshift, and has no disabling abilities to stop Slark.
Juggernaut
[wiki] rating: 0.4 (winrate: 52% pickrate: 19%)Spectre
* Juggernaut's 
Healing Ward can help save allied supports when Spectre attempts a Haunt kill.
* Juggernaut has a stronger push potential than Spectre, enabling him to end the game early before Spectre can come online.
* Spectre is often paired with two supports that are often weak against Juggernaut.
* Juggernaut also tends to build a Manta Style, which can prevent Desolate from taking effect.
* Juggernaut is invulnerable against Dispersion while using 
Omnislash.
Slark
* Heroes with escaping and disjointing abilities can be good against Juggernaut:
Anti-Mage 
Riki, Queen of Pain, Puck, 
Storm Spirit, 
Ember Spirit, Slark etc.
Puck
[wiki] rating: 0.4 (winrate: 52% pickrate: 17%)Slark
* 
Illusory Orb and 
Phase Shift allows Puck to avoid most ganking attempts.
* 
Waning Rift and 
Dream Coil makes it very hard for Slark to escape bad situations.
* Puck's abilities used together also deals significant magical nuke damage, none of which are targeted and thus cannot be avoided by Shadow Dance.
Slark
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, 
Earth Spirit, 
Faceless Void, Magnus, 
Mirana, 
Monkey King, Morphling, 
Pangolier, 
Phantom Assassin, 
Phoenix, Puck, Queen of Pain, Riki, 
Sand King, Spirit Breaker, Timbersaw, 
Tusk.
Sand King
[wiki] rating: 0.4 (winrate: 51% pickrate: 10%)Slark
* He has a hard time killing Sand King because of the survivability he gets from Burrowstrike and Sand Storm.
* Shadow Dance, which usually allows Slark to survive fights, is ineffective against Sand King's AoE damage.
Slark
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, Earth Spirit, Faceless Void, Magnus, Mirana, Monkey King, Morphling, Pangolier, Phantom Assassin, Phoenix, Puck, Queen of Pain, Riki, Sand King, Spirit Breaker, Timbersaw, Tusk.
Necrophos
[wiki] rating: 0.4 (winrate: 50% pickrate: 3%)Spectre
* 
Death Pulse can single out Spectre from her illusions, as well as heal his team against her. He also usually stands close to his allies for Death Pulse, effectively disabling Desolate.
Spectre
* Enemies that possess high defenses through magic resistance, damage reduction, or high regeneration will make it difficult to whittle their health down to get to Reaper's Scythe's threshold. Such heroes include Bristleback (although only from behind), Spectre, 
Ursa, and Dragon Knight.
Timbersaw
[wiki] rating: 0.4 (winrate: 48% pickrate: 8%)Slark
* Timbersaw can use 
Chakram as a scouting tool to find Slark if he tries to Pounce into the trees.
* None of Timbersaw's abilities require a target to be cast, allowing him to hit Slark inside Shadow Dance.
* 
Reactive Armor can be effective protection against a Slark who attacks quickly, since the strong armor and health regen cannot be stolen by Essence Shift.
* 
Timber Chain makes Timbersaw very mobile, meaning he is among the very few heroes who can actually give chase to a fleeing Slark.
Slark
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, Earth Spirit, Faceless Void, Magnus, Mirana, Monkey King, Morphling, Pangolier, Phantom Assassin, Phoenix, Puck, Queen of Pain, Riki, Sand King, Spirit Breaker, Timbersaw, Tusk.
Queen of Pain
[wiki] rating: 0.4 (winrate: 47% pickrate: 9%)Slark
* Both Scream of Pain and Sonic Wave should hit him during his Shadow Dance.
Slark
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, Earth Spirit, Faceless Void, Magnus, Mirana, Monkey King, Morphling, Pangolier, Phantom Assassin, Phoenix, Puck, Queen of Pain, Riki, Sand King, Spirit Breaker, Timbersaw, Tusk.
Faceless Void
[wiki] rating: 0.4 (winrate: 41% pickrate: 3%)Slark
* Time Dilation while Dark Pact and Pounce are on cooldown will make these abilities unusable for a long time, reducing his escape potential. However, Time Dilation is dispellable with Dark Pact so it needs to be timed well.
* Chronosphere will not reveal Slark during Shadow Dance, but covers the whole duration of Shadow Dance making him unable to use it to attack or escape. Slark still receives the regeneration benefit from Shadow Dance.
Slark
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, Earth Spirit, Faceless Void, Magnus, Mirana, Monkey King, Morphling, Pangolier, Phantom Assassin, Phoenix, Puck, Queen of Pain, Riki, Sand King, Spirit Breaker, Timbersaw, Tusk.
Phantom Assassin
[wiki] rating: -2.0 (winrate: 45% pickrate: 16%)Spectre
* Black King Bar is useless, since all of the Spectre's abilities go through spell immunity,
* Phantom Assassin's Blur cannot evade Desolate because its damage is a separate damage instance and is applied before the attack hits.
* Spectre's high durability provided by Dispersion and damage block items makes her one of the hardest carries to take down.
Additional:
* Dispersion makes it hard for Phantom Assassin to burst down Spectre while also reflecting back Phantom Assassin's high burst damage against herself.
* Desolate ignores the evasion from 
Blur.
* Black King Bar is useless against Spectre as all of her skills pierce spell immunity.
Slark
* Slark's Pounce allows him to close the gap on Phantom Assassin and prevent her from escaping with 
Phantom Strike.
* As a hero who always goes for the 
Silver Edge and 
Abyssal Blade Slark can use it to disable Phantom Assassin and her Blur and 
Coup de Grace, drastically reducing her damage output and ability to evade attacks, and also preventing her from acting.
* Phantom Assassin's Coup de Grace requires Random Number Generation in order to proc, which gives Slark more than enough time to escape and recover himself.
Rubick
[wiki] rating: -2.0 (winrate: 46% pickrate: 16%)Slark
* Pounce and Dark Pact together with some attacks can gank Rubick down quickly. Rubick can seldom retaliate because of the strong dispel of Dark Pact. What is more, Rubick is the type of squishy support that Slark exactly wants to gank.
* Though Shadow Dance is a great spell to steal, Slark's untargetable nature and his low cooldown spells prevents Rubick from stealing it.
* Slark usually builds Diffusal Blade which can prevent Rubick to cast his abilities from Spell Steal.
Spectre
* None of Spectre's spells are very good for Rubick to 
Spell Steal.
Drow Ranger
[wiki] rating: -2.0 (winrate: 47% pickrate: 4%)Spectre
* Spectre can easily close the distance on Drow Ranger with Haunt and stick on her with Spectral Dagger, negating the bonus agility from 
Marksmanship.
Slark
* A well-timed Dark Pact can dispel Frost Arrows and Gust, letting Slark engage and escape freely.
* Shadow Dance lets Slark quickly close the gap and deal heavy damage without giving Drow Ranger a chance to retaliate.
* Pounce counteracts Frost Arrows' slow, letting Slark easily pin Drow Ranger down or flee.
Additional:
* Pounce and items like Shadow Blade makes it very difficult for Drow Ranger to keep her distance from Slark, thereby losing her Marksmanship bonus.
* 
Gust is rarely enough to keep Slark at bay, as Drow Ranger has no movement abilities and will simply be chased down afterwards.
* Drow Ranger's heavy dependence on agility also makes her significantly weaker after being drained by Essence Shift.
Sniper
[wiki] rating: -2.0 (winrate: 49% pickrate: 6%)Spectre
* Haunt instantly allows her to get up and close with Sniper, and Spectral Dagger makes it difficult to escape from her.
* Spectre outcarries Sniper in the late game, so Sniper must try to end the game early before Spectre comes online.
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.
Slark
* Slark is a natural Shadow Blade carrier, and with Pounce Sniper has no opportunity to escape or react.
* With Essence Shift and Shadow Dance, Slark will easily win a fight against Sniper.
Additional:
* Sniper is one of the most gankable heroes in the game, and has no defenses when Pounced on by Slark.
Tinker
[wiki] rating: -2.0 (winrate: 54% pickrate: 12%)Spectre
* His global teleportation with 
Boots of Travel and 
Rearm is easily countered with Haunt, and Spectre can reach him anywhere on the map.
* He is squishy, and if alone Desolate will kill him very fast.
* 
Laser's blind isn't reliable, since Desolate cannot miss.
Slark
* Pounce prevents Tinker from blinking away.
* Slark frequently builds Shadow Blade, which allows him to approach Tinker unnoticed. Since Tinker's farming usually covers a significant amount of area on the map, Sentry Wards may not be cost effective.
* Shadow Dance allows Slark to detect both common and unusual wards. Eliminating common ward causes Tinker trouble farming many lanes if he does not know who may be waiting to jump on him. Slark is also uniquely able to identify some of the less common wards used by Tinker, such as those placed on the cliffs at map edges which Tinker uses to give him vision over the trees he uses to hide in.
* Slark's extremely high move speed from Shadow Dance, potentially stacked with Shadow Blade, allows him to easily follow Tinker between lanes, especially if Tinker has pushed the lanes out.
* Dark Pact dispels Laser's blind.
Nature's Prophet
[wiki] rating: -1.6 (winrate: 44% pickrate: 5%)Spectre
* Nature's Prophet can literally do nothing against Spectre, because she can chase him from anywhere with Haunt.
* Spectre, just like Naga Siren, loves buying Radiance, which can kill Nature's Prophet's treants, and grant her farm simultaneously.
Additional:
* Spectre can get to him anywhere on the map with Haunt.
* Spectre can pass through his trees with Spectral Dagger.
* Desolate's damage will melt him quickly, as he's alone most of the time.
Slark
* Pounce also stops 
Nature's Prophet's 
Teleportation.
Magnus
[wiki] rating: -1.6 (winrate: 44% pickrate: 4%)Slark
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, Earth Spirit, Faceless Void, Magnus, Mirana, Monkey King, Morphling, Pangolier, Phantom Assassin, Phoenix, Puck, Queen of Pain, Riki, Sand King, Spirit Breaker, Timbersaw, Tusk.
Spectre
* Spectre can use Haunt to intercept and disrupt Magnus's initiation attempts.
* Spectral Dagger can severely slow down Magnus after he uses 
Skewer.
* Magnus often travels alone when he is trying to initiate, so Desolate can be very effective against him.
Additional:
* Spectre disables Magnus' Blink Dagger using her ultimate, and later into the game can usually outlive Reverse Polarity's duration.
Bounty Hunter
[wiki] rating: -1.6 (winrate: 54% pickrate: 10%)Spectre
* Spectre can instantly reveal Bounty Hunter's position on the activation of her ultimate Haunt. She can also semi-reveal( visible but not target-able) Bounty Hunter by hitting him with Spectral Dagger.

Enigma
[wiki] rating: -1.6 (winrate: 55% pickrate: 8%)Spectre
* Haunt can ruin Enigma's initiation with Blink Dagger, no matter where he is on the map.
* Dispersion reflects the damage of Midnight Pulse and Black Hole inflicted back to Enigma.
Slark
* Enigma is fragile, and lacks escapes, being dependent on 
Blink Dagger for mobility. Ganking Heroes or Heroes with burst damage will likely kill him before he can do anything. Such Heroes include: Lina, Lion, Puck, Slark, Nyx Assassin, etc.
Lina
[wiki] rating: -1.4 (winrate: 46% pickrate: 9%)Slark
* Heroes with heavy magical nukes will take advantage of Slark's poor HP or force him to use Shadow Dance early: Lina, Lion, Zeus
Spectre
* Spectral Dagger and Haunt allow Spectre to get close to Lina.
* Desolate is very strong against Lina, who's usually a bit isolated in fights because of her high attack and cast range.
* Dispersion can mitigate a good portion of Lina's burst damage, allowing Spectre to turn on her afterwards.
Additional:
* Spectre can very easily close the distance on Lina with Haunt and Spectral Dagger, and due to Lina's abysmal mobility without a Blink Dagger and terrible health pool and armor, Lina easily gets slaughtered due Desolate.
* Dispersion can mitigate a good portion of Lina's burst damage, allowing Spectre to turn against her afterwards.
Slark
* Dark Pact can be cast during the cast animation of Light Strike Array and dispel its stun.
* Pounce allows Slark to close the gap to Lina.
* Shadow Dance prevents Lina from killing Slark with her Laguna Blade when his HP gets low.
Sven
[wiki] rating: -1.0 (winrate: 43% pickrate: 1%)Spectre
* Spectral Dagger hinders Sven's low movement speed, and can be an easy tool to escape against his high damage.
* Dispersion makes it harder for Sven to burst down Spectre in one on one fights, and can reflect Sven's high damage back to him or his nearby teammates.
* Haunt and Radiance disables Sven's Blink Dagger.
* Desolate's pure damage ignores Sven's high armor.
* Spectre should not attempt to stand up to a full slotted Sven, since she will get shredded.
Batrider
[wiki] rating: -1.0 (winrate: 47% pickrate: 1%)Slark
* Dark Pact can dispel Flaming Lasso if is used in anticipation, but a Blink initiation from fog can catch the Slark off guard.
* Slark can also take off any Sticky Napalm stacks with Dark Pact in lane.
Lifestealer
[wiki] rating: -1.0 (winrate: 48% pickrate: 5%)Slark
* Dark Pact can be used to remove Open Wounds.
* Shadow Dance allows Slark to attack Lifestealer for its duration without any way for Lifestealer to fight back.
* Slark commonly buys a Silver Edge, which can break Lifestealer's Feast, severely diminishing his damage output and lifesteal.
Earth Spirit
[wiki] rating: -1.0 (winrate: 48% pickrate: 10%)Slark
* Pounce's root prevents Earth Spirit from using Rolling Boulder to escape, making it easier for Slark to shut him down especially in the laning phase.
Earthshaker
[wiki] rating: -1.0 (winrate: 49% pickrate: 12%)Slark
* Earthshaker's many stuns can lock down slippery heroes like Slark in his Shadow Dance and Weaver in his 
Shukuchi.
Additional:
* Earthshaker's many AoE stuns help lock down Slark, and will often waste the duration of Shadow Dance.
Slark
* Heroes with invisibility and high mobility can jump on and focus down Earthshaker before he has a chance to initiate: Clinkz, Slark, Storm Spirit
Spectre
* Spectral Dagger can be used to traverse past Fissure.
* Haunt will usually disable Earthshaker's Blink Dagger prior to a teamfight, preventing him from initiating.
* On the other hand, Haunt will amplify damage done from Echo Slam. Use this to your advantage.
Additional:
* Spectre can use Haunt to intercept and disrupt Earthshaker's initiation attempts.
* Spectral Dagger can be used to traverse past 
Fissure.
* Earthshaker often travels alone when he is trying to initiate, so Desolate can be very effective against him.
* Beware that the Haunt illusions amplify the damage done from 
Echo Slam, which can prove fatal for Spectre's own team.
Pangolier
[wiki] rating: -1.0 (winrate: 49% pickrate: 12%)Slark
* Dark Pact easily purges away both slow and disarm effect from Lucky Shot.
* With Pounce now apply leash to the target, Pangolier is helpless against Slark since both his Swashbuckle and Rolling Thunder will be disabled. Pounce also help Slark to easily escape from Rolling Thunder.
Warlock
[wiki] rating: -1.0 (winrate: 50% pickrate: 4%)Slark
* 
Upheaval does not interrupt Slark too much, as he can just Pounce out of the area.
* 
Fatal Bonds and 
Shadow Word can be dispelled by Dark Pact.
Tidehunter
[wiki] rating: -1.0 (winrate: 50% pickrate: 10%)Slark

Oracle
[wiki] rating: -1.0 (winrate: 51% pickrate: 10%)Spectre
* Oracle's burst damage is ineffective against Dispersion.
* Disarm provided by Fate's Edict is not as significant debilitation for Spectre as it might be for other carries since She can do damage even without landing attacks.

* Dark Pact dispels Ignite's slow and Fireblast's stun.
* Shadow Dance allows Slark to regenerate HP, even when he is affected by Ignite and Fireblast.
Wraith King
[wiki] rating: -1.0 (winrate: 51% pickrate: 17%)Slark
* Dark Pact, if timed correctly, can dispel Wraithfire Blast's stun and slow.
* Since Wraith King has a lot of health and multiple lives, Slark can keep gaining Essence Shift stacks, increasing armor, damage, and attack speed and can beat down Wraith King twice.
* Slark sometimes carries Diffusal Blade to burn mana as an attempt to shut down Reincarnation.
* Because Wraith King has no AoE abilities, Shadow Dance is particularly useful against Wraith King.
Luna
[wiki] rating: -1.0 (winrate: 51% pickrate: 7%)Slark
* With Dust of Appearance, Luna will be able to use 
Eclipse on invisible heroes. Be mindful that Slark is exception because he'll be able to remove the debuff with Dark Pact.
Slark
* Shadow Dance prevents Luna from damaging Slark, and together with Shadow Blade he can kite her or escape.
* Luna has no way to escape from Pounce's leash.
Additional:
* Luna's lack of mobility and escape abilities makes her easily gankable by Slark.
* Shadow Dance will avoid all the damage from Eclipse.
* For the same reasons, Slark is a good ally for Luna when they are in the same team.
Spectre
* Heroes that create illusions (such as Spectre, Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, 
Terrorblade) or bring other units into the fight (such as Nature's Prophet, 
Lone Druid, Chen, 
Enchantress and the aforementioned 
Meepo and 
Arc Warden) can cause Eclipse to strike the illusions/summons unintentionally. (However, in many cases Moon Glaives can resolve this issue and eliminate them before activating Eclipse).

Additional:
* Spectre can catch up to her with Spectral Dagger, even if she uses 
Windrun.
* Spectre can instantly reach a ratting Windranger with Haunt.
* Windrun's miss chance is countered by Desolate.
* Dispersion can reflect some of her damage, especially from her 
Focus Fire.
Mirana
[wiki] rating: -1.0 (winrate: 51% pickrate: 16%)Slark
* If Slark sees the Sacred Arrow before it hits him, he can use Dark Pact to remove it a moment later.
* Pounce prevents Mirana from escaping with Leap.
* Slark can survive Mirana's Aghanim's Scepter combo with Shadow Dance.

[wiki] rating: -1.0 (winrate: 51% pickrate: 16%)Slark
* Slark can detect early Roshan attempts due to Shadow Dance if he frequently checks the Pit.
* Enrage cannot restore attributes stolen by Essence Shift and will reduce his physical damage output.

Alchemist
[wiki] rating: -1.0 (winrate: 53% pickrate: 14%)Slark
* Shadow Dance allows Slark to not be targeted by Unstable Concoction, making Alchemist stun himself and making himself vulnerable to the enemy.
* Dark Pact also allows him to just purge off the stun if timed correctly.

* Pounce can easily break Static Link, making it less powerful against him.
* Slark is one of the few heroes who can man fight a Razor, because of Essence Shift.
* Shadow Dance can prevent Razor from killing him and may provide an opportunity to kill Razor due to it preventing Razor from attacking Slark.
Medusa
[wiki] rating: -0.6 (winrate: 45% pickrate: 2%)Spectre
* Stone Gaze negates Dispersion's damage reduction and allows Medusa to kite Spectre.
* Spectre's small mana pool is depleted quickly by Mystic Snake.
* Split Shot can clear Haunt illusions quickly.
Spectre
* Heroes that build Diffusal Blade or can fit it well into their item build will also make Medusa much less tanky: Riki, Naga Siren, Terrorblade, Juggernaut, Spectre, Slark,
Drow Ranger.
Slark
* Medusa cannot chase Slark in any way and has no disable beyond her ultimate, making her unable to stop him getting away and regenerating before coming back to finish her off.
* Essence Shift removes 1 of every attribute, lowering Medusa's mana pool's cap and leaving her much more vulnerable in prolonged fights.
Additional:
* Medusa is especially vulnerable to Essence Shift, as both strength and intelligence contribute to her effective HP, while agility contributes to her damage.
* Dark Pact when timed right can be used to dispel Stone Gaze right after it petrifies Slark, allowing him to keep attacking Medusa throughout the duration.
Vengeful Spirit
[wiki] rating: -0.6 (winrate: 45% pickrate: 3%)Slark

Riki
[wiki] rating: -0.6 (winrate: 48% pickrate: 5%)Spectre
* Riki's 
Smoke Screen can make it hard for Spectre to escape or burst down Riki with auto attacks.
* Riki can build Aghanim's Scepter and jump inside an allied carry or offlane tank with 
Tricks of the Trade to do a lot of damage to Spectre while completely avoiding Dispersion.
* Riki is great at destroying supports which are often needed to keep Spectre safe until she comes online. He can take them down quickly in team fights, which will leave Spectre alone against your whole team, a fight that she will most likely not win.
* While on Tricks of the Trade, Riki does not take damage from Dispersion.
Spectre
* Spectral Dagger follows Riki even after he goes invisible and stays on him through Tricks of the Trade, revealing his location.
* Desolate grants Spectre the ability to damage Riki with right clicks regardless of Smoke Screen's blind.

Monkey King
[wiki] rating: -0.6 (winrate: 50% pickrate: 16%)Spectre
* Dispersion will not do anything against throughout the game due to his high lifesteal with Jingu Mastery.
* Monkey King often buys Manta Style, which will deny Desolate benefits in 1v1 situations.
* Haunt will do nothing to stop people trapped within Monkey Kings ultimate.
* In all, Spectre is very easily pressured by Monkey King early into the game and is a very easy gank target to coordinate with your team.
Spectre
* Spectral Dagger maintains vision on Monkey King, and allows Spectre to chase Monkey King into the trees.
* Haunt will still spawn an illusion next to Monkey King while under the effects of Mischief, removing the disguise.
* Monkey King attack range is exactly 300. The best range for Dispersion buff.

* Weak damage but high tick rate or persist in a long time: Slark, Gyrocopter, Queen of Pain, 
Shadow Shaman (
Shackles), 
Pugna
* 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), Pugna
Additional:
* Dark Pact rips through 
Refraction charges and still steals attributes during Refraction.
* Pounce and Dark Pact will still hit Templar Assassin while she is 
Melded. Since she cannot move, both abilities will be easy for Slark to land.

* Heroes with good escapes can usually outmaneuver and escape from Spectre: Slark, Clinkz, Weaver

* 
Hex can be used immediately to destroy Spectre's illusion when she Haunts.
* Shadow Shaman can use Shackles to lock down Spectre for his team.
* Shadow Shaman's 
Mass Serpent Ward and 
Ether Shock help him push lanes and end the game early before Spectre can come online and take over the late game.
Slark
* Nyx Assassin, 
Bounty Hunter and Slark can all sneak up and kill you, Nyx being particularly deadly. Watch Slark carefully, as he can break either (but not both unless you are making a mistake) of your disables, with Dark Pact and leap out of a serpent ward ring. These heroes, however, rely heavily on escape and are themselves not very durable and none of them can survive a full lockdown with Mass Serpent Ward. Having Sentry Wards can turn you from prey to predator.
Spectre
* Spectre's entire ability set is designed to get to and destroy heroes that stay in the backlines, both carries (like the aforementioned Drow Ranger and Sniper) and supports (like Dazzle and Shadow Shaman).
Keeper of the Light
[wiki] rating: 0.0 (winrate: 45% pickrate: 4%)Slark

Sven, Slark
Slark
* Heroes with dispels: Legion Commander, Oracle, Slark
Pudge
[wiki] rating: 0.0 (winrate: 46% pickrate: 19%)Spectre
* Pudge's Dismember does not allow Spectre to escape with Haunt.
* He can easily tank the damage reflected by Dispersion due to his high strength and the healing from Dismember.
* Should Spectre try to get away through the trees or over a cliff with Spectral Dagger, Pudge can hook her back.
* Spectre takes a long time to come online, and Pudge can ruin her early game with ganks.
Slark
* Dark Pact dispels Dismember if timed perfectly.
* Pudge's low attack speed and poor agility can be lowered even further by Essence Shift.
* Shadow Dance grants Slark invisibility and a high degree of mobility, which can make Slark a difficult target to hook and also protects him from Pudge's Dismember (including allies with an Aghanim's Scepter).
Zeus
[wiki] rating: 0.0 (winrate: 46% pickrate: 8%)Spectre
* Zeus is good against heroes that juke in trees or up cliffs, like 
Batrider, Monkey King, Spectre, and 
Tinker, by providing vision in any area with Lightning Bolt, or guaranteeing vision on enemies with Thundergod's Wrath.
Slark
* Heroes with heavy magical nukes will take advantage of Slark's poor HP or force him to use Shadow Dance early: Lina, Lion, Zeus
Slark
* Zeus can deal a huge amount of damage, but he lacks defensive abilities, such as good mobility or resistance. Due to that, he doesn't like to be touched by any means. Heroes with higher damage output and good mobility will often get easily near Zeus and trade damage (eventually causing Zeus's downfall). Such Heroes include: Lycan, Slark, Storm Spirit, Spectre and others.

Axe
[wiki] rating: 0.0 (winrate: 47% pickrate: 8%)Slark
* Berseker's Call catches Slark in Shadow Dance, wasting its duration and preventing him from escaping to regenerate.

Blade Mail.
Additional:
* 
Berserker's Call forces Slark to attack him, even during Shadow Dance.
* 
Counter Helix will hit Slark in Shadow Dance, with pure damage. It also triggers frequently against Slark's high attack speed after having stolen agility with Essence Shift.
* 
Culling Blade finishes off Slark before he gets a chance to slip away and regenerate his health, preventing him from playing the hit-and-run style often associated with Slark.
Spectre
* Dispersion makes Spectre very durable, making it much less likely for Axe to bring her low enough for Culling Blade.
* Spectre can simply use Spectral Dagger to escape against an Axe gank.
Dazzle
[wiki] rating: 0.0 (winrate: 48% pickrate: 5%)Slark
* Heroes that can deny Slark early kills will prevent him from snowballing: Dazzle, Abaddon
Spectre
* Spectre's entire ability set is designed to get to and destroy heroes that stay in the backlines, both carries (like the aforementioned Drow Ranger and Sniper) and supports (like Dazzle and Shadow Shaman).
Winter Wyvern
[wiki] rating: 0.0 (winrate: 49% pickrate: 7%)Spectre
* 
Arctic Burn makes it nearly impossible for Spectre to juke into the trees.
* 
Cold Embrace negates all of Spectre's physical damage. Furthermore, Cold Embrace will generally outheal Desolate.
* 
Winter's Curse can taunt illusions, not only wasting the entire duration of Haunt but also turning its illusions against Spectre's own team.
Slark
* Arctic Burn and Splinter Blast debuffs are dispellable with Dark Pact. Arctic Burn is also no escape against Pounce.
* Cold Embrace just gives Slark free Essence Shift stacks. He also relies mostly on magic damage early in the game.

Ancient Apparition
[wiki] rating: 0.0 (winrate: 52% pickrate: 10%)Slark
* 
Ice Blast stops Shadow Dance's passive health regeneration, even when Slark is not in vision.
Spectre
* As Ancient Apparition likes to stay far away from the fight to get full effectiveness from Ice Blast, he is a very good target for a Haunt gank.
* Ancient Apparition also has no hard disables and escape spells, making him an easy kill for Spectre.
Slark
* Bulwark blocks much of Slark's basic attack damage, even during
Shadow Dance.
Shadow Dance.
Pounce be on cooldown, Slark is very vulnerable inside Arena of Blood.
* Slark finds it very difficult to have a good early/mid game when pressured in the early game by Spear of Mars and God's Rebuke.

Spectral Dagger inside and outside from Arena of Blood, but it doesn't really matter since Mars does best during the early and mid game.
* Spectre can use
* Should Spectre get to the late game, Mars can block a large amount of her damage and split the teamfights in his advantage.
