Zeus
[wiki] rating: 2.0 (winrate: 49% pickrate: 11%)Phantom Lancer
[wiki] rating: 2.0 (winrate: 49% pickrate: 7%)Luna
* Phantom Lancer creates many illusions to tank Luna's Eclipse.
* 
Doppelganger can be used to dodge a number of Lucent Beams during Eclipse.
* Phantom Lancer can chase Luna effectively regardless of her high movement speed thanks to 
Phantom Rush and 
Spirit Lance.
* Although her Moon Glaives kill his illusions quickly, Luna's low health pool is easily exploited by the sheer damage output from his illusions.
Bounty Hunter
* Doppelganger dispels 
Track.
* Bounty Hunter also has no area of effect abilities to help with the illusions.
Rubick
[wiki] rating: 2.0 (winrate: 47% pickrate: 17%)Luna
* 
Lucent Beam is a solid magic nuke.
* 
Eclipse can cause massive damage if cast in the right time.
* Rubick has a good chance to steal Eclipse for Luna has only two cast abilities.
* 
Aghanim's Scepter greatly increased the effectiveness of the ability, including more damage as well as longer cast range. In addition, it allows him to cast it on another hero so Rubick doesn't have to get close to the enemy team in teamfights.
Bounty Hunter
* Rubick is a potential counter to Bounty Hunter as he can steal his Track and use it against his invisibility, and also provide his team with more gold if the tracked hero is killed.
Juggernaut
[wiki] rating: 1.6 (winrate: 53% pickrate: 20%)Bounty Hunter

Time Lapse
* 
Tidehunter with 
Kraken Shell when damage received reaches the threshold.
Luna
* Because of her low range, Luna cannot easily destroy 
Healing Ward.
* Both Blade Fury and 
Omnislash are direct counters to Eclipse, offering Juggernaut spell immunity.
Chaos Knight
[wiki] rating: 1.6 (winrate: 51% pickrate: 4%)Luna
* 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).
Bounty Hunter
* Phantasm dispels Track, and the illusions make it difficult to Track the real Chaos Knight.
* Bounty Hunter is fragile and can easily be killed by Chaos Knight and Phantasm's illusions.
Death Prophet
[wiki] rating: 1.6 (winrate: 50% pickrate: 3%)Bounty Hunter
* Death Prophet's 
Silence allows her to prevent Bounty Hunter from escaping with Shadow Walk.
* If Bounty Hunter cannot escape with Shadow Walk while affected by Silence, she will be able to burst him down with 
Crypt Swarm and 
Spirit Siphon.
Luna
* A couple of long-range heroes with excellent laning like 
Mirana, 
Lina, 
Necrophos, 
Death Prophet. The key to success is sticking together and attacking Luna whenever she enters the range, without even giving Luna a chance to retaliate. Multiple long-range heroes is a reason to pick another hero.
Techies
[wiki] rating: 1.6 (winrate: 48% pickrate: 6%)Luna
* Luna has low HP, low range and often stalks through jungle. She cannot properly disarm 
Proximity Mines and could fall victim to their traps.
* Of course, if Luna happens to catch Techies off-guard, they won't be able to survive for long against Eclipse, Lucent Beam, and right-clicks.
Bounty Hunter
* Techies is very good against roaming supports and gankers such as 
Bounty Hunter, 
Riki, Weaver, 
Earthshaker, 
Nyx Assassin, etc. that are constantly moving around the map.
Spectre
[wiki] rating: 1.6 (winrate: 46% pickrate: 7%)Bounty Hunter

Luna
* 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).
Bristleback
[wiki] rating: 1.6 (winrate: 45% pickrate: 7%)Bounty Hunter
* 
Bristleback's 
Viscous Nasal Goo can catch and slow Bounty Hunter. 
Warpath and 
Quill Spray can defeat him quickly due to his small HP pool when compared to Bristleback's.
Luna
* Quill Spray and 
Bristleback harass Luna more efficiently than she does with Lucent Beam.
* Bristleback withstands Luna’s nukes, and gives lots of damage in return.
* Viscous Nasal Goo and Warpath are enough to outrun a speedy Luna.
* Bristleback tends to be a frequent carrier of 
Crimson Guard, which is good protection from bouncing glaives.
Additional:
* Multiple instances of damage from Eclipse will trigger Bristleback's passive repeatedly in a short time, dealing tremendous damage to Luna and her teammates.
* Luna's damage burst may be high, but it will not be enough for her to take down Bristleback.
Abaddon
[wiki] rating: 1.2 (winrate: 53% pickrate: 3%)Luna
* Every hero that can withstand or prevent Eclipse at level 7: Juggernaut, Riki,

* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Additional:
* Bounty Hunter is a single target dealer, so he will not fare well against Naga Siren. He might as well try to Track her, but her Mirror Image will dispel the effect. Also, Ensnare reveals invisible units while they're rooted, putting Bounty Hunter in a tricky situation.
Luna
* 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).
Storm Spirit
[wiki] rating: 1.2 (winrate: 50% pickrate: 10%)Luna
* Escape-type carries: Slark, 
Storm Spirit, Weaver.
Bounty Hunter

[wiki] rating: 1.0 (winrate: 56% pickrate: 2%)Luna
* Her Spiderlings can harass Luna in lane heavily, as Luna has no AoE abilities to clear Spiderlings.
* Broodmother can knock down towers in the early game quickly, and limit Luna's farming space.
Venomancer
[wiki] rating: 1.0 (winrate: 51% pickrate: 5%)Bounty Hunter
* Venomancer's magical damage-over-time poisons greatly reduce Bounty Hunter's mobility.
* 
Venomous Gale, 
Plague Wards and 
Poison Nova with True Sight items can allow Venomancer and his teammates to gank Bounty Hunter while he is roaming alone.
Bloodseeker
[wiki] rating: 1.0 (winrate: 51% pickrate: 2%)Bounty Hunter
* 
Rupture can turn Bounty Hunter's mobility against him, and prevents him from escaping with Shadow Walk due to the potentially heavy damage.
* 
Thirst can prevent Bounty Hunter from escaping with Shadow Walk should Bounty Hunter's health become low enough, as it provides True Sight.
Slark
[wiki] rating: 1.0 (winrate: 48% pickrate: 12%)Luna
* 
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.
Bounty Hunter
* Slark with Dark Pact
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury

* Ursa with Enrage
* Weaver with Time Lapse

Luna
* 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.
Viper
[wiki] rating: 1.0 (winrate: 48% pickrate: 7%)Bounty Hunter
* Viper's poison abilities can slow Bounty Hunter's movement speed and allows to chase him with True Sight items.

* Meepo can tank Eclipse because of his clones.
*

Lina
[wiki] rating: 1.0 (winrate: 47% pickrate: 14%)Luna

Black King Bar, making Lina even more of a threat.
Night Stalker
[wiki] rating: 0.6 (winrate: 53% pickrate: 5%)Bounty Hunter
* 
Night Stalker's 
Crippling Fear at night prevents Shadow Walk for an extended period of time and his 
Void will make Phase Boots useless. If Night Stalker has True Sight, he can shutdown Bounty Hunter's sneak kill.
Wraith King
[wiki] rating: 0.6 (winrate: 53% pickrate: 21%)Bounty Hunter
* Heroes that are naturally hard to gank, ranging from beefy tanks like Abaddon and Wraith King to heroes with quick escape mechanisms like Anti-Mage and Storm Spirit are also undesirable targets for a lone, roaming Bounty Hunter to scout out and initiate on.

* Every hero that can withstand or prevent Eclipse at level 7: Juggernaut, Riki, Clockwerk, Drow Ranger, Abaddon, Faceless Void, Weaver, Outworld Destroyer.

Lion
[wiki] rating: 0.6 (winrate: 49% pickrate: 15%)Bounty Hunter
* Finger of Death can instantly shred many targets especially fragile Heroes like 
Keeper of the Light, 
Ancient Apparition, or Bounty Hunter.
Anti-Mage
[wiki] rating: 0.6 (winrate: 48% pickrate: 14%)Bounty Hunter
* Heroes that are naturally hard to gank, ranging from beefy tanks like Abaddon and Wraith King to heroes with quick escape mechanisms like Anti-Mage and Storm Spirit are also undesirable targets for a lone, roaming Bounty Hunter to scout out and initiate on.
Grimstroke
[wiki] rating: 0.6 (winrate: 47% pickrate: 8%)Luna
* Hard-hitters who relies mostly on raw stats or good passive and therefore make a perfect target for 
Dark Portrait: Naga Siren, Faceless Void, Terrorblade, Luna, Anti-Mage
Shadow Demon
[wiki] rating: 0.6 (winrate: 46% pickrate: 3%)Luna
* 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:
* Demonic Purge takes off Luna's superior mobility, removing the need for chasing her and allowing your team to reposition in team fights or escape when at low HP. If Shadow Demon has Aghanim's Sceptre it will also take away glaive bounces and extra damage from Luna's passive.
* Luna's illusions created by Disruption are very valuable with their 
Moon Glaives. These will effectively counter her pushing attempts and are painfully effective in team fights.
* Disruption can be used to save an ally from Eclipse.

* A couple of nukers and disablers on the same lane can finish a squishy Luna efficiently despite a teammate's assistance: 
Sven + 
Shadow Shaman.
Spirit Breaker
[wiki] rating: 0.4 (winrate: 51% pickrate: 8%)Bounty Hunter
* Spirit Breaker's 
Charge of Darkness semi-reveals Bounty Hunter, taking away his element of surprise for the duration of the charge. Also, as Charge of Darkness shows Bounty Hunter's position, Spirit Breaker's allies can proceed to gank Bounty Hunter while he is roaming alone.
Luna
* Heroes who continue dealing damage while being stunned: Luna, 
Razor, 
Axe, Bristleback, 
Leshrac,
Slardar
[wiki] rating: 0.4 (winrate: 48% pickrate: 9%)Bounty Hunter
* 
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.
Additional:
* Bounty Hunter's 
Shadow Walk is rendered useless with Corrosive Haze and makes Bounty Hunter an easy target for Slardar and his team.
Luna
* Illusion heroes like the aforementioned Phantom Lancer or Naga Siren, or heroes that tend to buy 
Manta Style, like Luna or Juggernaut, will give Slardar a hard time, as his damage is single-targeted.

* Tidehunter with Kraken Shell when damage received reaches the threshold.
Luna
* Luna often builds Black King Bar, and none of Tidehunter's spells can bypass spell immunity.
* Lucent Beam and Eclipse deal a lot of magic damage in the early and mid-game, which can bypass Kraken Shell.
Io
[wiki] rating: -1.6 (winrate: 47% pickrate: 4%)Bounty Hunter
* Fragile heroes: Bounty Hunter has decent nuking capabilities with Shiruken Toss and Jinada thus making fragile heroes easy picks for ganking. Few examples of such heroes are:Crystal Maiden, 
Pugna, 
Skywrath Mage, 
Io, Witch Doctor, etc.
Luna
* Lucent Beam can cancel Tether and Relocate.
* Moon Glaives and Eclipse make short work of Io and its tethered ally.
Shadow Fiend
[wiki] rating: -1.6 (winrate: 47% pickrate: 19%)Luna
* Heroes with high burst damage: Lina, 
Lion, Luna, Nyx Assassin, 
Queen of Pain.
Bounty Hunter
* Bounty Hunter can absolutely destroy a Shadow Fiend's game by ganking his midlane with Shadow Walk, Jinada and Shuriken Toss.
* If his lane goes bad, a Shadow Fiend usually goes to the jungle. Follow him with Shadow Walk and take half of his experience.
* Due to its ministun, Shuriken Toss is a good way to interrupt Shadow Fiend's long cast animation on 
Requiem of Souls.
Additional:
* 
Shuriken Toss can be used to cancel Requiem of Souls.
* Shadow Walk and 
Jinada allow Bounty Hunter to gank Shadow Fiend early on
* Track prevents Shadow Fiend from escaping with Shadow Blade.
Witch Doctor
[wiki] rating: -1.6 (winrate: 47% pickrate: 12%)Bounty Hunter
* Low mobility heroes: Heroes with no/little means of traveling fast have difficulty getting to/away from Bounty Hunter due to his slowing Jinada and hastening Track. Few examples of such heroes are: Crystal Maiden, Sniper, Ursa, Witch Doctor, etc.
Luna
* Lucent Beam interrupts Death Ward from a decent range.
* Eclipse kills Witch Doctor during Death Ward, even through 
Glimmer Cape.
Pugna
[wiki] rating: -1.6 (winrate: 51% pickrate: 4%)Bounty Hunter
* Fragile heroes: Bounty Hunter has decent nuking capabilities with Shiruken Toss and Jinada thus making fragile heroes easy picks for ganking. Few examples of such heroes are:Crystal Maiden, Pugna, Skywrath Mage, Io, Witch Doctor, etc.
Luna
* 
Life Drain will be always canceled by Lucent Beam if Pugna does not have Black King Bar.
* 
Decrepify can be suicide against Luna due to Lucent Beam and Eclipse.
* 
Nether Ward is rather weak against Luna since she does not have abilities that cost a lot of mana.
Additional:
* Luna can shrug off most damage taken from Nether Ward as she only has two castable skills with average mana cost.
* Luna can deal constant damage to Pugna through the low-cooldown Lucent Beam and her right clicks.
* Lucent Beam's considerable range can reliably cancel Pugna's Life Drain.
* Luna is a common Black King Bar carrier, which totally nullifies Pugna's damage output.
* If Pugna uses Decrepify on himself to avoid Luna's right click, she can burst him down with Lucent Beam and Eclipse.
Crystal Maiden
[wiki] rating: -1.4 (winrate: 50% pickrate: 13%)Bounty Hunter
* Frostbite will reveal invisible heroes for its duration, making it a good tool against any such hero (Riki, Bounty Hunter, Weaver, or Clinkz for example), or as a soft counter to Shadow Blade, if it is used first. This can be an amazing tool to ensure that Dust of Appearance is used on the unit in question, and not wasted in not catching anything.
Bounty Hunter
* Shuriken Toss's stun is useful for cancelling Freezing Field from a distance.
* Track can be used for revealing Crystal Maiden when she uses Glimmer Cape.
* Jinada does burst physical damage (which is even bigger if dealt under Track's crits), which is effective due to Crystal Maiden's low HP and armor.
* Bounty Hunter likes to stay hidden from the fight and is less likely to get caught by Crystal Maiden's spells.
Luna
* Lucent Beam allows Luna to easily cancel Freezing Field.
* Without Black King Bar protection, Lucent Beam and Eclipse can make a short work out of Crystal Maiden's abysmal health.
* Skilled Luna will always buy Dust of Appearance, allowing her team to have a vision on Crystal Maiden while invisible and during channeling Freezing Field.
Riki
[wiki] rating: -1.4 (winrate: 54% pickrate: 10%)Luna
* All assassin-type carries in a one against one situation: Meepo, Phantom Assassin, Riki, Ursa.
Luna
* Luna can push very fast with Moon Glaives, which is something Riki cannot deal with well.
* Luna is naturally very fast, making it hard for Riki to trap her in Smoke Cloud.
* Even though Riki can evade Eclipse with his invisibility, smart Luna will always buy Dust of Appearance, providing vision on Riki to her allies and herself.
Bounty Hunter
* Track gives Riki a hard time, as it prevents much of his ganking capabilities.
Magnus
[wiki] rating: -1.0 (winrate: 46% pickrate: 7%)Luna
* If Luna can use Eclipse in anticipation, Magnus will be killed before he can even manages to cast 
Reverse Polarity.
* Aghanim's Scepter upgraded Eclipse is a very good counter-initiation tool against Magnus when he casts Reverse Polarity, granted as long as Luna can cast it from safe distance.
Nature's Prophet
[wiki] rating: -1.0 (winrate: 47% pickrate: 4%)Luna
* 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).
Luna
* Moon Glaives and 
Lunar Blessing help Luna to tear off Nature's Prophet's treants.
* Luna can easily cancel Teleportation with her Lucent Beam.
Bounty Hunter
* Heroes with detection: Bounty Hunter, 
Disruptor, Razor, 
Slardar, Spectre, 
Spirit Breaker
Queen of Pain
[wiki] rating: -1.0 (winrate: 48% pickrate: 9%)Luna
* Aggressively blinking is not going to end well against Luna, because Queen of Pain will be an easy target for Lucent Beam & Eclipse.
* Queen of Pain's HP is abysmal, so Luna can quickly kill Queen of Pain as soon as she initiates with Blink.
Chen
[wiki] rating: -1.0 (winrate: 50% pickrate: 1%)Luna
* 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).
Bounty Hunter
* Invisibility heroes can sneak past Chen's creeps and pick him off: Nyx Assassin, Weaver, Bounty Hunter Riki.
Luna
* Moon Glaives can easily clear Chen's creeps while Eclipse can kill Chen's allies before he can react.
Additional:
* Luna's Moon Glaives and Lunar Blessing can easily kill Chen's creeps.
Undying
[wiki] rating: -1.0 (winrate: 50% pickrate: 7%)Luna
* Luna has Moon Glaives and Lunar Blessing to help her destroy Tombstone, and this becomes more effective if Luna is equipped with Manta Style.
* Defending with Zombies from Tombstone against Luna is not a good idea because Eclipse will strike only Undying.
Void Spirit
[wiki] rating: -1.0 (winrate: 51% pickrate: 10%)Bounty Hunter
* One hit with Jinada should be sufficient in removing Void Spirit's shield most of the time.
* Track negates much of Void Spirit's escape abilities by revealing his position and prevents him from rotating effectively.
Visage
[wiki] rating: -1.0 (winrate: 51% pickrate: 3%)Luna
* Moon Glaives is effective at destroying Familiars and will remove one instance of Gravekeeper's Cloak upon each hit to Visage, leaving him susceptible to damage.
Winter Wyvern
[wiki] rating: -1.0 (winrate: 51% pickrate: 5%)Luna
* Cold Embrace is no salvation against Lucent Beam and Eclipse.
* Moon Glaives will not hit a hero affected by Winter's Curse, making it weak against allies, but strong versus enemies.
* Luna has better night vision provided by Lunar Blessing than Winter Wyvern when affected by Arctic Burn.

Nyx Assassin
[wiki] rating: -1.0 (winrate: 55% pickrate: 11%)Bounty Hunter
* Nyx Assassin wants to start ganking as soon as he gets his 
Vendetta. Keeping him Tracked prevents him from ganking, and thus from doing his job in the game.
* Nyx Assassin has a lot of armor and health regen, making the nuke damage from Shuriken Toss very good against him.
Additional:
* Track hinders Nyx Assassin's ganking attempts with Vendetta, making him an easy kill for gold as well.
Earthshaker
[wiki] rating: -0.6 (winrate: 49% pickrate: 10%)Luna
* Luna's Lucent Beams and Eclipse will prevent Earthshaker from initiating or re-initiating.
Templar Assassin
[wiki] rating: -0.6 (winrate: 49% pickrate: 5%)Bounty Hunter
* Because Templar Assassin does not have escape potential in lane, any support hero with roaming potential and a Dust of Appearance can be great at shutting her down early game: 
Earth Spirit, Spirit Breaker, 
Tusk, Bounty Hunter, Riki, 
Warlock.
Skywrath Mage
[wiki] rating: -0.6 (winrate: 50% pickrate: 6%)Bounty Hunter
* Fragile heroes: Bounty Hunter has decent nuking capabilities with Shiruken Toss and Jinada thus making fragile heroes easy picks for ganking. Few examples of such heroes are:Crystal Maiden, Pugna, Skywrath Mage, Io, Witch Doctor, etc.
Invoker
[wiki] rating: -0.6 (winrate: 50% pickrate: 18%)Bounty Hunter
* Bounty Hunter and Slardar both have ultimates (Corrosive Haze and Track) that reveal Invoker through Ghost Walk.
Treant Protector
[wiki] rating: -0.6 (winrate: 52% pickrate: 6%)Bounty Hunter
* Invisibility reliant heroes: Heroes with invisibility abilities or those that have invested into invisibility items are hindered by Bounty Hunter's Track. Few examples of such heroes are:Clinkz, Riki, 
Treant Protector, etc.
Ancient Apparition
[wiki] rating: -0.6 (winrate: 52% pickrate: 8%)Bounty Hunter
* Heroes with mobility/escape mechanisms to dodge Ancient Apparition abilites, or to easily jump on him: Riki, Queen of Pain, Phantom Assassin, 
Windranger, Bounty Hunter, Spirit Breaker, Night Stalker, Storm Spirit, Juggernaut, etc.
Clinkz
[wiki] rating: -0.6 (winrate: 53% pickrate: 6%)Bounty Hunter
* Invisibility reliant heroes: Heroes with invisibility abilities or those that have invested into invisibility items are hindered by Bounty Hunter's Track. Few examples of such heroes are:Clinkz, Riki, Treant Protector, etc.
Additional:
* Track reveals Clinkz if he tries to escape with Skeleton Walk, allowing Bounty Hunter to gain lots of gold if he kills Clinkz.
* Jinada with physical damage items can quickly kill Clinkz due to his low health.
Monkey King
[wiki] rating: -0.6 (winrate: 54% pickrate: 18%)Bounty Hunter
* 
Monkey King is also hindered by Track since he relies on trees to hide him from vision.
Additional:
* Track grants vision of Monkey King, even when he's in the trees.
Enchantress
[wiki] rating: -0.4 (winrate: 44% pickrate: 2%)Luna
* 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).
Luna
* Enchantress has pitiful HP so Lucent Beam and Eclipse can kill her very quickly.
* Moon Glaives allows Luna to clear Enchantress' creeps very efficiently.
Additional:
* Enchantress has pitiful HP, even more pitiful than Luna, so Lucent Beam and Eclipse will often harass and/or kill her through her Untouchable.
* With Moon Glaives, Luna can clear Enchantress's creep wave efficiently.
Lifestealer
[wiki] rating: -0.4 (winrate: 45% pickrate: 5%)Bounty Hunter
* Lifestealer with Rage and Infest
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with Mirror Image
* Omniknight with Heavenly Grace
* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Luna
* Although he can avoid Eclipse with Rage and Infest, Luna's physical damage can be enough to deal with him.
* Manta Style is a common pick on Luna, which can help her dispel 
Open Wounds. In addition, Lifestealer is not good against illusions created by Manta Style.
Legion Commander
[wiki] rating: -0.4 (winrate: 49% pickrate: 13%)Bounty Hunter
* Legion Commander with Press the Attack
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with Mirror Image

* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Luna
* Provided Luna is able to cast it in time, Eclipse can help win a 
Duel from Legion Commander.
* If Luna isn't the target, she can easily use Lucent Beam and Eclipse to win the fight for the ally.
Additional:
* A well-timed Eclipse before a Duel usually prevents Legion Commander from winning Duels, if Luna is the target.
* Meanwhile, when Luna is not a target, Eclipse and Lucent Beam can also help an ally win a Duel against Legion Commander.
* However, skilled Legion Commander players will always have a Black King Bar or Aghanim's Scepter handy since both abilities do not pierce through spell immunity.
Necrophos
[wiki] rating: -0.4 (winrate: 49% pickrate: 4%)Luna
* A couple of long-range heroes with excellent laning like Mirana, Lina, Necrophos, Death Prophet. The key to success is sticking together and attacking Luna whenever she enters the range, without even giving Luna a chance to retaliate. Multiple long-range heroes is a reason to pick another hero.
Luna
* Though Luna has a hard time laning against Necrophos, his 
Ghost Shroud won’t protect him in teamfights because it will increase the damage from Lucent Beam and Eclipse.
Omniknight
[wiki] rating: -0.4 (winrate: 50% pickrate: 3%)Bounty Hunter
* Omniknight with Heavenly Grace
* Heroes that can remove the Track debuff with their skills:

* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with Mirror Image

* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Luna
* Guardian Angel does not offer protection from Eclipse, though it will negate damage from Moon Glaives.
Bane
[wiki] rating: -0.4 (winrate: 51% pickrate: 5%)Luna
* Low-health, normally mobile carries with a lot of damage are vulnerable to Bane's nukes and disables: Anti-Mage, Clinkz, Drow Ranger, Faceless Void, 
Gyrocopter, Juggernaut, Luna, Meepo, Mirana, Monkey King, 
Morphling, Phantom Assassin, Phantom Lancer, Riki, 
Shadow Fiend, Slark, Sniper, Terrorblade, Troll Warlord, Weaver.
Luna
* It is almost impossible for Bane to use 
Fiend's Grip properly against Luna's allies due to the huge cast range of the Lucent Beam.
Additional:
* Luna's Lucent Beam can be used to disable Bane while he is channeling Fiend's Grip.
* Luna's Eclipse will often be able to kill Bane before he can even act.
Arc Warden
[wiki] rating: -0.4 (winrate: 51% pickrate: 5%)Luna
* 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).
Luna
* Luna's Moon Glaives allow her to clear Arc Warden's 
Tempest Double.
* Luna's short range and fast movement speed allow her to fight Arc Warden inside his 
Magnetic Field.
Underlord
[wiki] rating: -0.4 (winrate: 54% pickrate: 8%)Bounty Hunter
* In general, melee heroes without blink mechanisms or spell immunity will have a hard time positioning against Pit of Malice: Sven, 
Tiny, Wraith King, 
Dragon Knight, Meepo, 
Doom, Bounty Hunter, 
Dark Seer, 
Undying, 
Alchemist, Legion Commander.
Luna
* Lunar Blessing gives allies bonus damage and armor required to endure against Atrophy Aura early on.
* Eclipse can be devastating for Underlord's team when they're grouped up for Dark Rift, it can also be used to intercept arrivals with Dark Rift. And Pit of Malice does not prevent Luna to use it.
* To make things even better, Aghanim's Scepter upgraded Eclipse can finish off Underlord or any of his teammates escape attempts with Dark Rift if timed correctly.

Terrorblade
[wiki] rating: 0.0 (winrate: 46% pickrate: 6%)Luna
* 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).
Luna
* Heroes that can stall pushes: 
Invoker, Keeper of the Light, Lina, Luna.
Pudge
[wiki] rating: 0.0 (winrate: 47% pickrate: 22%)Luna
* 
Flesh Heap's magic resistance allows him to survive Eclipse, and 
Meat Hook and 
Dismember can disable Luna through her Black King Bar.
* However, Lucent Beam can still cancel Dismember from a safe distance, even if its damage is going to be reduced.
Additional:
* Pudge can easily survive Luna's Lucent Beam and Eclipse, and his Meat Hook and Dismember can pierce Black King Bar, making Luna one of the perfect victims for ganking.
* However, Lucent Beam can cancel Dismember, as Pudge often doesn't build Black King Bar, and if she is farmed enough, Luna might be able to fight back against Pudge.
Bounty Hunter
* Bounty Hunter can easily keep vision on Pudge with Track, making it difficult for Pudge to hook Bounty Hunter or his team mates.
* It's difficult for Pudge to keep up with Bounty Hunter to apply 
Rot on him due to Shadow Walk.
* Shuriken Toss cancels out Dismember from a good range if Bounty Hunter is not the target.
Additional:
* Track can easily keep vision on Pudge, making it impossible to catch up with his Meat Hook for Bounty Hunter's teammates or him.
* It's very difficult for Pudge to use Rot on and hook Bounty Hunter due to Shadow Walk.
* Shuriken Toss cancels out Dismember from a good range.
Sniper
[wiki] rating: 0.0 (winrate: 48% pickrate: 5%)Luna
* Sniper usually sits at the back and it's hard for Luna to get close to him to attack.
* Due to Sniper's 
Shrapnel and his long range, Luna has a hard time taking high ground despite her Moon Glaives being fantastic for taking Barracks and buildings.
Bounty Hunter
* Bounty Hunter can use Shadow Walk to get close, and Jinada can do massive damage and slow down Sniper on the first attack.
* Track gives additional speed to Bounty Hunter and makes Shadow Blade useless, allowing Bounty Hunter to easily kill him with a few attacks.
Additional:
* Sniper relies on distance. Bounty Hunter can use Shadow Walk to get close, and Jinada can do massive damage and slow down Sniper in the early game.
* Track gives additional speed to Bounty Hunter and makes Shadow Blade useless, which can allow Bounty Hunter to easily kill him with a few attacks.
Tinker
[wiki] rating: 0.0 (winrate: 49% pickrate: 8%)Luna
* Tinker's 
March of the Machines and 
Laser both destroy Luna's small health pool and make it hard for Luna to initiate with Eclipse (and making it hard to land glaives in Laser's case).
* Since Tinker typically buys 
Blink Dagger, Luna has a hard time catching him despite her high movement speed.
* Tinker can easily disable and nuke Luna down with 
Dagon or 
Scythe of Vyse before she can use Lucent Beam or Eclipse.
Luna
* Luna can easily prevent Tinker from escaping with 
Boots of Travel or Rearm with Lucent Beam.
* Luna can also quickly tear Tinker to shreds with Eclipse as soon as he jumps in with Blink Dagger.
Mirana
[wiki] rating: 0.0 (winrate: 51% pickrate: 16%)Luna
* A couple of long-range heroes with excellent laning like Mirana, Lina, Necrophos, Death Prophet. The key to success is sticking together and attacking Luna whenever she enters the range, without even giving Luna a chance to retaliate. Multiple long-range heroes is a reason to pick another hero.
Bounty Hunter
* Heroes with spells that negate invisibility such as Bounty Hunter, 
Zeus and Slardar prevent her from saving her allies with Moonlight Shadow.
Shadow Shaman
[wiki] rating: 0.0 (winrate: 52% pickrate: 13%)Luna
* A couple of nukers and disablers on the same lane can finish a squishy Luna efficiently despite a teammate's assistance: Sven + Shadow Shaman.
Bounty Hunter
* 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.
Bounty Hunter
* Bounty Hunter has a very low health pool, allowing Zeus to burst him down quickly.
Shadow Walk, Zeus can gain vision of him with both Lightning Bolt and Thundergod's Wrath.
Lightning Bolt makes roaming behind enemy lines more and more difficult as Zeus becomes powerful enough to spam it. Also, Zeus' Ultimate 
Thundergod's Wrath reveals Bounty Hunter regardless of his position.
* Zeus can cast Lightning Bolt to gain True Sight in any area he suspects Bounty Hunter may be invisible or any area he thinks Bounty Hunter may have warded.
* If Bounty Hunter tries to escape a gank by using
Additional:
*
Luna
* His highly damaging nuke spells with low cooldowns is not something Luna wants to go against.
Thundergod's Wrath can be used before a fight to harm Luna before she activates her Black King Bar, reducing her survivability for that fight.
*
