* 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.

* Pounce and Dark Pact together with some attacks can take Rubick down quickly.
* Rubick's spells are ineffective due to the strong dispel effect of Dark Pact.
* Even though Shadow Dance is a great spell to steal, Slark's untargetable nature and his low cooldown spells prevents Rubick from stealing. Also Slark can freely use other abilities for the duration of Shadow Dance.

* 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.

* 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.

* Batrider has poor survivablilty, relying on his mobility from Firefly to survive. Stunning him with Ice Path of Liquid Frost can easily spell his doom.
* Batrider tends to cast Flaming Lasso on the squishest or the tankiest hero. Which Jakiro is not squishy, nor his generally the tank of the team, Due to this, Jakiro can usually save allies with Ice Path and Liquid Frost, while also potentially removing an entire hero from play for a short period of time.
* Even if Batrider does cast Flaming Lasso on Jakiro, Batrider will generally drag Jakiro into a great setup for Ice Path and Macropyre.

* 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.
Additional:
* Shadow Dance's passive can inform Slark when he's under enemy vision, meaning it'll be very hard to catch Slark off-guard with Flaming Lasso.
* Flaming Lasso is dispelled by Dark Pact. Its casting can be prevented with Shadow Dance or Depth Shroud (it requires Aghanim's Shard).

* All of Jakiro's active skills can be targeted on an area, which is effective at forcing Templar Assassin to move should she Meld away.
* Many of Jakiro's spells utilize damage-over-time mechanics, which makes it easy to strip away layers of Refraction.

* 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.

* Dual Breath, Liquid Fire, Liquid Frost from Aghanim's Shard and Macropyre allows Jakiro can clear Chen's creeps, and kill his allies before he uses Hand of God.
* Macropyre can quickly clear Chen's creeps and deal intense damage to his allies, Aghanim's Scepter upgraded Macropyre can also deal pure damage to Chen and his creeps and allies and pierce spell immunity.
Additional:
* Jakiro's damage over time force Chen to use Hand of God prematurely, potentially wasting chance to save his allies during teamfight.
* Dual Breath and Macropyre can be used to disrupt Chen's jungling work.

* 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.

* Jakiro's abilities deal damage over time, which can disrupt Magnus's attempts to initiate with Blink Dagger and Reverse Polarity.
* Macropyre not only disables Blink Dagger for a considerable duration, but can also destroy Trees, revealing Magnus's cover and position.

* 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.

* Jakiro's skill arsenal can ruin Nature's Prophet's gameplay: Dual Breath and Liquid Fire can clear treants from Nature's Call while simultaneously slowing Nature's Prophet, Ice Path can disrupt Nature's Prophet's escaping attempt with Teleportation, and Macropyre can easily clear treants from Nature's Call.
* Jakiro is a common Hurricane Pike wielder, which allows him to escape from Sprout.
Additional:
* Jakiro's Macropyre can help him to escape from Sprout and quickly clears Treants.
* Jakiro can disrupt Nature's Prophet's escape attempt with Sprout and Teleportation by using Ice Path.

* Pounce also stops Nature's Prophet's Teleportation.

* 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.

* Essence Shift deals 20 extra damage by draining one strength per hit, which cannot be reduced or spread by Dispersion.
* Pounce prevents Spectre from escaping with Spectral Dagger.
* Haunt illusions usually don't deal a lot of damage to Slark as he tends to buy a Shadow Blade, preventing Desolate's and Diffusal Blade's damage and activating Shadow Dance's regeneration to make up for any damage caused by Radiance.
* Slark is a natural carrier of Silver Edge, which helps break both Desolate and Dispersion.

* Heroes with channeling spells are very easy targets for Jakiro's abilities: Crystal Maiden, Dawnbreaker, Enigma, Pudge, Shadow Fiend, Shadow Shaman, Warlock.

* Dark Pact dispels Dismember if timed correctly.
* Pounce allows Slark to escape Pudge's Rot once Dismember is over, and allows him to dodge hooks.
* Shadow Dance hides Slark and grants him a high degree of mobility, which can make him a difficult target to hook and also protects him from Pudge's Dismember (including allies with an Aghanim's Shard).

* Riki can easily be caught in an Ice Path and Macropyre combo as he finishes Tricks of the Trade, Jakiro just has to be careful about Riki's Smoke Screen when dealing with Riki.

* 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.

* Jakiro's area-of-effect ability arsenal allows him to affect multiple heroes at once, giving Io difficulties in saving them as he can only heal one hero at a time with Tether.
* Ice Path can be used to cancel both, Tether and Relocate.
* Jakiro commonly buys Rod of Atos that can be used to cancel Relocate, prevent Io in escaping with Tether and make Io easy target for Ice Path and Macropyre.

* Heroes that can easily bypass Io's allies to get to Io: Riki, Tusk, Clinkz, Sniper, Slark, Phantom Assassin, Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, Spirit Breaker, Lifestealer.

* Heroes with channeling spells are very easy targets for Jakiro's abilities: Crystal Maiden, Dawnbreaker, Enigma, Pudge, Shadow Fiend, Shadow Shaman, Warlock.

* 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.

* Most of the of Jakiro's damage-over-time abilities put Blink Dagger on cooldown, potentially forcing Enigma to prematurely activate Black King Bar.
* Jakiro's Dual Breath, Liquid Fire, Macropyre and Liquid Frost from Aghanim's Shard can take out Enigma's Eidolons, reduce Enigma's attack speed and put Enigma's Blink Dagger on cooldown.
* Jakiro can easily cancel Black Hole with Ice Path as Enigma is a very easy target while channeling it.
* Aghanim's Scepter upgraded Macropyre can deal pure damage-over-time and pierce spell immunity, which can discourage Enigma from even trying to initiate with Black Hole.
Additional:
* Most of the of Jakiro's damage-over-time abilities put Enigma's Blink Dagger on cooldown, potentially forcing him to prematurely activate Black King Bar.
* Jakiro's Dual Breath, Liquid Fire, Macropyre and Liquid Frost from Aghanim's Shard can take out Enigma's Eidolons, reduce Enigma's attack speed and put Enigma's Blink Dagger on cooldown.
* Jakiro can easily cancel Black Hole with Ice Path as Enigma is a very easy target while channeling it.
* Aghanim's Scepter upgraded Macropyre can deal pure damage-over-time and pierce spell immunity, which can discourage Enigma from even trying to initiate with Black Hole.

* Enigma lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Enigma finishes his initiation: Faceless Void, Terrorblade, Ursa, Weaver, Broodmother, Slark, Abaddon, Wraith King, Lifestealer.

* Jakiro's area-of-effect abilities make him strong against heroes who rely on illusions and summons: Terrorblade, Naga Siren Chaos Knight, Phantom Lancer, Broodmother, Nature's Prophet, Lycan, Wraith King, Visage.

* 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.

* Mana Drain can be easily canceled with Ice Path. However, Lion can counter this by buying his Aghanim's Shard though, that is no longer possible, but Jakiro can counter this too with Aghanim's Scepter upgraded Macropyre will deal pure damage through the debuff immunity forcing Lion to cancel it or die.
* Lion has very strong single target capabilities, but usually struggles against multiple heroes, while Jakiro has good multi-target capabilities, His abilities also have a much shorter cast range then Jakiro's, allowing Jakiro to cast his abilities before he can get off his Hex or Earth Spike.
* Jakiro can also save an ally who Lion is attempting to Finger of Death by casting Ice Path on Lion.

* Lion's lack of escapes gives Slark easier time to catch him through Pounce.
* Shadow Dance gives Slark the advantage of being untargetable, nullifying single target abilities (such as non-upgraded Hex, Mana Drain and Finger of Death).
* Dark Pact applies multiple instances of strong dispel on Slark, which is strong against any of Lion's disables.
* Lion's low health pool and low armor make him extremely vulnerable to Slark's damage output.

* Even though Luna can easily kill Jakiro in few strikes, he can also do the same to her is she is not careful.
* Dual Breath and Liquid Fire allow Jakiro to harass Luna more efficiently than she can harass Jakiro with her Lucent Beam.
* Jakiro can save his allies from Luna during her attempts to use Eclipse by casting Ice Path on Luna.
* Aghanim's Scepter upgraded Macropyre can deal pure damage-over-time and pierce spell immunity, which can make it very hard for Luna to be in teamfights without suffering too many damage.
* For the same reasons, Jakiro makes a very powerful ally for Luna when they are in the same team.
Additional:

* For the same reasons, Jakiro makes a very powerful ally for Luna when they are in the same team.

* Shadow Dance prevents Luna from damaging Slark, and together with Silver Edge he can easily chase her or escape from her.
* Luna has no way to escape from Pounce's leash.
* For the same reasons, Slark makes a very powerful ally for Luna when they are in the same team.
Additional:
* Luna's lack of mobility and escape abilities makes her easily to gank for Slark.
* Shadow Dance helps avoid all the damage from Eclipse.
* For the same reasons, Slark makes a very powerful ally for Luna when they are in the same team.

* Even though carry Silencer can easily take down a support Jakiro with his Glaives of Wisdom, Jakiro can also do the same to Silencer if he is not careful and if Jakiro is not played as support. As Silencer is rather squishy and lacks escape mechanisms without items, and Jakiro's damage over time abilities can take advantage of this.
* Ice Path can be used to prevent Silencer from escaping. And if Jakiro uses Ice Path along with Macropyre and Dual Breath in anticipation right before Silencer uses his abilities to disable Jakiro, Jakiro will be able to kill Silencer before he even gets a chance to do anything to Jakiro.
* Dual Breath, Liquid Fire and Liquid Frost from Aghanim's Shard can greatly reduce Silencer's attack speed.
* Aghanim's Scepter upgraded Macropyre can deal huge pure damage to Silencer even if Silencer is spell immune.
* Bear in mind, however, that Jakiro should approach Silencer carefully as Silencer's Arcane Curse, Last Word and Global Silence prevents Jakiro from casting any spell. Jakiro, however, can counter this by going for Guardian Greaves, a common item on support Jakiro, and with Black King Bar and Manta Style, a situational items on Jakiro.

* Slark's Dark Pact allows him to dispel Silencer's debuffs.
* Against a carry Silencer, Essence Shift will lower damage from both Glaives of Wisdom and his basic attack.

* Jakiro relies entirely on dealing damage through his area-of-effect abilities, making Enfeeble less effective against him, although it will still reduce his cast range.
* An ill-timed Nightmare can give Jakiro a good setup for all of his ablities.
* Jakiro can easily cancel Fiend's Grip with Ice Path, as Bane is very easy target while channeling it.
* Aghanim's Scepter upgraded Macropyre can deal pure damage-over-time and pierce spell immunity, which can discourage Bane from even trying to use Fiend's Grip.

* Dark Pact can dispel Enfeeble, as well as Nightmare and Fiend's Grip when timed correctly.
* Shadow Dance can protect Slark from Bane's single-target abilities.

* Tinker's Laser has very little effect on Jakiro.
* Tinker has to sit still for a short period of time due to Rearm, not only making it easy to catch him with Ice Path, but also by stunning him while he is Rearming, Jakiro generally spell Tinker's doom.
* With s high area-of-effect and strong damage-over-time capabilties, Jakiro can quickly burn through his Defense Matrix, and at the same time lock down his Blink Dagger. Both of which he relies heavily to survive on.

* 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.

* 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.

* 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.

* Jakiro's area-of-effect abilities make him strong against heroes who rely on illusions and summons: Terrorblade, Naga Siren Chaos Knight, Phantom Lancer, Broodmother, Nature's Prophet, Lycan, Wraith King, Visage.

* Lycan cannot escape from a Pounce even if he uses Shapeshift, and has no disabling abilities to stop Slark.

* Heroes who rely on damage over time as Spiked Carapace can block and reflect only one instance of damage: Jakiro, Viper, Venomancer, Huskar, Ember Spirit, Dark Seer, Sand King, Doom, Dawnbreaker. However, this also means they are easily stunned.

* 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.

* Heroes that can slow Charge of Darkness by a huge amount: Venomancer, Viper, Dazzle, Arc Warden, Lion, Huskar, Shadow Shaman, Visage, Undying, Jakiro.

* 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.

* Heroes with channeling spells are very easy targets for Jakiro's abilities: Crystal Maiden, Dawnbreaker, Enigma, Pudge, Shadow Fiend, Shadow Shaman, Warlock.

* Nyx Assassin, Bounty Hunter and Slark can all sneak up and kill Shadow Shaman, Nyx being particularly deadly. Shadow Shaman must watch out for Slark carefully, as he can break either (but not both unless he makes a mistake) of Shadow Shaman's 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 Shadow Shaman from prey to predator.

* Jakiro's wide area-of-effect abilities allow him to clear the waves of Terrorblade's illusions and to damage real Terroblade.
* Both, Liquid Fire and Liquid Frost from Aghanim's Shard deal magical damage, which can bypass Terrorblade's high armor.
* Jakiro often buys Hurricane Pike, which combined with +275 Attack Range talent allows Jakiro to harass Terrorblade from safe distance without getting in range of Sunder and outrange Terrorblade greatly, even during Metamorphosis.
* Aghanim's Scepter upgraded Macropyre can deal huge pure damage to Terrorblade and his illusions and can hurt real Terrorblade even if he is protected by Black King Bar thanks to it's ability to pierce spell immunity when upgraded.
* Just bear in mind, however, that Jakiro's abilites are all dealing damage-over-time, so a well-timed Sunder may spell a doom for Jakiro if Terrorblade can get close to him unless Jakiro builds Black King Bar or Linken's Sphere and other items that can give him a burst damage.

* Dark Pact can dispel Venomous Gale and Poison Sting.
* Shadow Dance allows Slark heightened regeneration when out of vision making DoTs effects less threatening.

* Dark Pact easily purges away both slow and disarm effect from Lucky Shot.
* With Pounce now applying 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.

* 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.

* While Jakiro's damage is going to be little more then average against him due to his Bristleback. His large quantity of stuns can prevent Bristleback from getting his much needed Warpath stacks, while also giving his allies a chance to counter his high defense.
* Dual Breath and Liquid Frost both reduce Movement Speed, removing one of Bristlebacks greatest strengths.
* Liquid Fire reduces Bristlebacks Attack Speed, making it harder for him to burst down a hero with Warpath.
* However Bristleback can generally catch and kill a lone Jakiro. And Jakiro is only effective in a group.

* Essence Shift allows Slark to hit Bristleback freely whether on the front or back, stealing attributes and make Bristleback much less tanky.
* Pounce can be used to disengage and recover lost HP with his ultimate passive, and can return to fight in a short period while Bristleback is already injured and got some of his attributes stolen.
* Dark Pact makes it near impossible to keep the Viscous Nasal Goo debuff on Slark.
* Although Dark Pact cannot dispel Quill Spray, meaning that Slark will still receive quill stack damage even if he used Shadow Dance before.
* Slark builds Silver Edge in almost every game, an item that greatly counters Bristleback.

* Slark's Pounce can be used to dodge Hoodwink's abilities or lock her down.
* Shadow Dance makes Slark unhittable from Acorn Shot.
* Dark Pact removes all slows from Hoodwink's abilities.
* Hoodwink's already low health output is a great target for Slark's Essence Shift.

* A well-timed Dark Pact can dispel Frost Arrows and Gust, letting Slark engage and escape freely.
* Essence Shift is very detrimental for Drow Ranger as the loss of agility means that Marksmanship will also suffer from getting weakened.
* Shadow Dance lets Slark quickly close the gap and deal heavy damage without giving Drow Ranger a chance to retaliate.
* Pounce counteracts Frost Arrows's slow, and also allows Slark easily pin Drow Ranger down or flee from her.
* Depth Shroud from Aghanim's Shard will allow Slark to save both, himself and his allies and will also allow them to freely fight back against Drow Ranger without her noticing them.
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.

* 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.

* 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.

* Jakiro's area of effect abilities can hit Dark Willow even while she is hidden during the Shadow Realm.
* Waiting about 2 seconds after Dark Willow casts Shadow Realm to cast Ice Path will stun her while her Shadow Realm is at it's maximum damage.
* Jakiro can stun Dark Willow when there is about 1 second left on Cursed Crown, Jakiro's Ice Path stun lasts slightly longer then Cursed Crown.

* Jakiro's reliance on his abilities can cause struggles for heroes who rely on evasion or blinds to get upper hand: Phantom Assassin, Windranger, Riki, Troll Warlord, Keeper of the Light.

* Pounce helps put Windranger in place, even when she uses Windrun to escape.
* Shadow Dance avoids Windranger's attacks from Focus Fire altogether, and he can regenerate his health and fight back after Windranger uses up all her abilities.
* The stun from Shackleshot and the slow fromPowershot can be both dispelled by Dark Pact, provided Slark casts it at the right moment.

* Jakiro's reliance on his abilities can cause struggles for heroes who rely on evasion or blinds to get upper hand: Phantom Assassin, Windranger, Riki, Troll Warlord, Keeper of the Light.

* Slark's Pounce allows him to close the gap on Phantom Assassin and prevent her from escaping with Phantom Strike.
* As a hero who typically builds Silver Edge, Slark can use it to disable Phantom Assassin's Blur and Coup de Grace, thus taking down her attack evasion and drastically reducing her damage output.
* Because Phantom Assassin is always reliant on critical strikes, Slark will have plenty of time to escape with Pounce, Shadow Dance and Silver Edge (provided that he purchased it already).
* Depth Shroud from Aghanim's Shard will allow Slark to save both, himself and his allies from Phantom Assassin with Shadow Dance, and to freely fightback against her without removing invisibility upon attacking.
* Essence Shift is much more harmful for Phantom Assassin than for other heroes, as losing the agility means that her physical damage will be also reduced, which can also weaken Coup de Grace if Slark manages to steal lots of agility from her.
* Overall, any attempt for Phantom Assassin to take down Slark will hurt her more than Slark.
Additional:

* Overall, any attempt for Phantom Assassin to take down Slark will hurt her more than 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.
* Essence Shift will steal stats over long durations at a time should Alchemist lack the damage to kill Slark.

* 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.

* 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.

* Both Ice Path and Macropyre are the good setup against Earthshaker after he jumps in with Blink Dagger, and stay out of Echo Slam initiation radius.
* Jakiro's damage over time abilities can potentially disable Earthshaker's Blink Dagger.

* Heroes with invisibility and high mobility can jump on and focus down Earthshaker before he has a chance to initiate: Clinkz, Slark, Storm Spirit

* Broodmother and her Spiderlings need to be very careful during the laning stage against Jakiro, as Jakiro can take down Broodmother's Spiderlings, preventing her from pushing as well as gaining a good amount of gold.

* Arctic Burn and Splinter Blast's debuffs are can be dispelled with with Dark Pact. Arctic Burn also cannot be used to escape against Pounce.
* Even though Cold Embrace can protect it's owner from Slark's direct attacks, Slark can still gain Essence Shift stacks from attacking heroes affected by it.
* However, Essence Shift works against allies, and Slark's low health pool means that if he's the target for Winter's Curse, he will go down very quickly as Winter's Curse cannot be dispelled at all.

* 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.
Additional:
* 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 particularly removes 1 intelligence point per hit, thus lowering Medusa's mana pool's cap and leaving her much more vulnerable in prolonged fights.

* 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.
* Even if Ursa initiates with Earthshock, Slark can Pounce away or use Dark Pact after Ursa's initiation to avoid Fury Swipes' damage until Earthshock's slow is gone.

* With Dual Breath, Liquid Fire and Macropyre Jakiro can quickly remove all Living Armor from a target.
* Ice Path allows Jakiro to prevent Treant Protector from using Overgrowth while staying at a safe distance.

* Heroes with strong dispels can remove Primal Roar's stun: Abaddon, Slark, Oracle.

* Jakiro has 3 damage over time spells, 2 of which are from debuffs on Puck (Dual Breath and Liquid Fire) and 1 affecting an entire area (Macropyre), making it easy for him to disable the Blink Dagger.
* Ice Path is also strong against Puck, as he can cast it towards Puck during Phase Shift, who then gets instantly stunned once Phase Shift ends.

* Weaver with Time Lapse

* Jakiro's area-of-effect abilities make him strong against heroes who rely on illusions and summons: Terrorblade, Naga Siren Chaos Knight, Phantom Lancer, Broodmother, Nature's Prophet, Lycan, Wraith King, Visage.

* Melee carries who usually buy an early Black King Bar, and have gap closing abilities can be good against the Arc Warden, such as Slark, Riki, Earthshaker with Aghanim's Scepter, Sven with Aghanim's Scepter etc.

Additional:
* Flux is dispelled by Dark Pact.
* Pounce allows Slark to avoid Spark Wraiths.
* Tempest Double allows Slark to build up Essence Shift stacks, especially when it is being used for split pushing.

* Jakiro's damage over time abilities can clear Naga Siren's illusions and can hurt real Naga Siren even for the duration of Song of the Siren.
* Naga Siren is not a hero that likes to go for Black King Bar, and that makes her very vulnerable to Jakiro's damage over time in every phase of the game.
Additional:
* Jakiro's damage over time abilities can clear Naga Siren's illusions and can hurt real Naga Siren even for the duration of Song of the Siren.
* Since Naga Siren is a hero who barely goes for Black King Bar, this can make her very vulnerable to Jakiro's damage over time in every phase of the game.

* Sniper hugely lacks mobility and escape abilities so that he is an easy target for ganks from 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.

* Weaver has poor health, relying on Shukuchi and Time Lapse to survive, With Jakiro's considerable arsenal of stuns, Weaver cannot initiate on Jakiro without being punished heavily or even killed in return.
* While difficult, Ice Path can catch Weaver during Shukuchi, And since Shukuchi only lasts 4 seconds while Ice Path's stun lasts 3.5, the stun from Ice Path will strip him of his escape.
* Weaver has to be very careful casting Time Lapse around Jakiro, as it could very easily put him inside of a Macropyre or Ice Path.

* All of Jakiro's skills are Area of Effect, which can easily affect all Meepos in a targeted area.

* 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.

* Jakiro's spells inflict AoE damage, meaning he can take down Phantom Lancer's illusion army very quickly.
* Bear in mind, however, that once Phantom Lancer buys Diffusal Blade which can burn Jakiro's mana, Jakiro will be vulnerable to Phantom Lancer 's counter-attacks if he runs out of mana.
Additional:
* Jakiro's AoE abilities are great against Phantom Lancer:
* Dual Breath slows down and damages Phantom Lancer and his illusions.
* Liquid Fire will not only deal AoE damage but also lowers Phantom Lancer's attack speed.
* Ice Path and Macropyre combo can easily clear all of Phantom Lancer's illusions.
* Jakiro can predict Doppelganger and Ice Path on top.

* Jakiro's abilities all deal magical damage over time, which allows him to attack Muerta even through Pierce the Veil.
* Dual Breath and Liquid Fire can be used to harass Muerta on lane.
* Ice Path can be used to stun Muerta when she uses Pierce the Veil, giving his allies time to escape or counter-initiate against Muerta.
* Aghanim's Scepter upgraded Macropyre can deal pure damage and pierce debuff immunity, rendering both, Pierce the Veil and Black King Bar useless.
* However, Jakiro is vulnerable to Muerta's The Calling as it can easily silence him due to his low mobility. In addition, Liquid Fire and Liquid Frost from Aghanim's Shard will not be able to be used on Muerta while Pierce the Veil is active unless she is near the enemy hero Jakiro targets with Liquid Fire and Liquid Frost or until Jakiro buys Revenant's Brooch.

* 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.

* With his AoE damage, Jakiro can easily kill Chaos Knight's Phantasm illusions.
* Chaos Knight usually doesn't buy a Black King Bar, making him vulnerable to an Ice Path into Macropyre combination.

* Chaos Knight usually doesn't buy a Black King Bar, making him vulnerable to an Ice Path into Macropyre combination.

* Dual Breath and Liquid Fire reduces Tiny's already abysmal Attack Speed.
* If Tiny Tosses a hero onto Jakiro, he can react with Ice Path, and potentially Macropyre.
* Tiny's Avalanche is easily countered with Ice Path.
* As Tiny has a very high Health, Liquid Frost is particularly effective against him.

* Ice Path allows Jakiro to easily cancel Freezing Field.
* Freezing Field makes Crystal Maiden an easy target for all of his abilities without a Black King Bar.
* With the Aghanim's Scepter upgraded Macropyre, Black King Bar becomes nearly useless for Crystal Maiden, as its high pure damage over time, long duration and ability to pierce spell immunity will either force Crystal Maiden to forcefully cancel Freezing Field or even discourage her from using it at all.
Additional:
* Ice Path allows Jakiro to easily cancel Freezing Field.
* Freezing Field makes Crystal Maiden an easy target for all of Jakiro's abilities without a Black King Bar.
* Aghanim's Scepter upgraded Macropyre can deal pure damage-over-time and pierce spell immunity, making Black King Bar nearly useless for Crystal Maiden, as its high damage over time and long duration can discourage Crystal Maiden to use Freezing Field. Remember, however, that Crystal Maiden can partially solve this issue by buying Aghanim's Shard, which will allow her to simply walk out of Macropyre.

* 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.

* Despite Jakiro's fragileness, he can easily harass Shadow Fiend with Dual Breath and Liquid Fire than Shadow Fiend can harass Jakiro with Shadowraze.
* Jakiro can easily cancel Requiem of Souls with Ice Path as Shadow Fiend is a very easy target while channeling it.
* Aghanim's Scepter upgraded Macropyre can deal pure damage-over-time and pierce spell immunity, which can discourage Shadow Fiend from even trying to initiate with Requiem of Souls.

* Both Jakiro's Ice Path and Liquid Frost can be used to cancel Life Drain from either Jakiro or an ally.
* Decrepify only makes Pugna even more vulnerable to Jakiro's magical damage, And it has no adverse effects on Jakiro himself.
* Aghanim's Scepter upgraded Macropyre can deal pure damage-over-time and pierce debuff immunity, which can discourage Pugna from even trying to use Life Drain.
* Bear in mind, however, that Nether Ward can do some considerable damage to Jakiro due to high mana costs on his abilities.

* Dark Pact dispels debuffs from Gush, Anchor Smash and even Ravage if timed correctly.
* Kraken Shell cannot restore attributes stolen by Essence Shift or dispel the leash if he gets Pounced.

* Heroes with escaping and disjointing abilities can be good against Juggernaut:Anti-Mage Riki, Queen of Pain, Puck, Storm Spirit, Ember Spirit, Slark etc.

Additional:
* Blade Fury does not offer any protections against Essence Shift, as it can go through spell immunity and reduces attribute.
* Slark can pounce away from Juggernaut and he cannot prevent or chase slark.
* Shadow Dance prevent Juggernaut from using Omnislash altogether, while regen himself at a higher rate. Slark can freely hit juggernaut without any fears of retaliation.

* Clockwerk lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Clockwerk finishes his initiation. Additionally, Clockwerk hates buying Dagon and Ethereal Blade, which are the only itmes that can help him deal with heroes who can recover themselves and turn the fight around to their advantage: Faceless Void, Terrorblade, Ursa, Weaver, Broodmother, Slark, Abaddon, Wraith King, Lifestealer.

* 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.

* Shadow Dance allows Slark to attack Lifestealer for its duration without any way for Lifestealer to fight back, allowing him to steal his stats with Essence Shift, which also reduces Lifestealer's strength and, therefore, health pool.
* Slark can easily escape Lifestealer with Pounce, and can avoid Open Wounds with Dark Pact should Lifestealer be forced to itemize for it.
* Slark commonly buys a Silver Edge, which can break Lifestealer's Feast, severely diminishing his damage output and lifesteal.
* Depth Shroud from Aghanim's Shard allows Slark to save both, himself and his allies with Shadow Dance while also allowing them to fight back against Lifestealer.

* Ice Path is a great stun for Berserker's Call and with a Eul's Scepter of Divinity can really catch Axe off guard.
* Dual Breath and Liquid Fire can be a devastating combination for Axe (especially if he takes Battle Hunger at level 1) before he has any natural regeneration sustain from items.
Additional:
* Ice Path neutralizes initiation attempts with Berserker's Call, and its long area of effect discourages follow-ups from Axe's teammates until Axe buys Black King Bar.
* Ice Path serves as a large obstacle to stop Axe from chasing down fleeing stragglers to kill with Culling Blade until Axe buys Black King Bar.
* Jakiro's many damage-per-second skills prevent Axe from initiating with his Blink Dagger. Forcing Axe to buy Black King Bar prematurely to protect himself against Jakiro's abilities and counter-initiaions.

* Jakiro's area-of-effect abilities that deal magical damsge make it hard for Omniknight to save multiple enemy heroes at once with Purification and Repel, and Guardian Angel and to harass Omniknight on lane.
* Aghanim's Scepter upgraded Macropyre allows Jakiro to deal pure damage and slow enemy heroes which can pierce debuff immunity, rendering both Repel and Guardian Angel useless.
