[wiki] rating: 1.6 (winrate: 51% pickrate: 16%)Underlord
* Provided Ursa can stack Fury Swipes reliably, Atrophy Aura won't do much against it.
* With Overpower, Fury Swipes, and Enrage Ursa could kill Underlord before the latter escapes with 
Dark Rift.
Additional:
* 
Fury Swipes damage is not reduced by Atrophy Aura, essentially bypassing Underlord's only natural defense.
* 
Enrage can quickly dispel the root of Pit of Malice.
Luna
* All assassin-type carries in a one against one situation: 
Meepo, 
Phantom Assassin, 
Riki, 
Ursa.

Juggernaut, Riki, 
Clockwerk, 
Drow Ranger, 
Abaddon, 
Faceless Void, 
Weaver, 
Outworld Destroyer.
Underlord
* 
Arcane Orb 's pure damage can do great damage to Underlord.
* 
Sanity's Eclipse can tear down Underlord's health by a large amount, since his mana pool is very low compare to OD's high mana pool.
Sniper
[wiki] rating: 1.6 (winrate: 49% pickrate: 6%)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.
Underlord
* Heroes who Sniper can kite: 
Sven, 
Wraith King, 
Kunkka, 
Doom, 
Tidehunter, 
Underlord, 
Troll Warlord, and etc.
Additional:
* Sniper's very long range allows him to stay out of Firestorm and Pit of Malice as well as Atrophy Aura range.
Techies
[wiki] rating: 1.6 (winrate: 48% pickrate: 8%)Underlord
* In general, heroes that provide vision will see Dark Rift coming: 
Techies, 
Templar Assassin, 
Treant Protector
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.
Clockwerk
[wiki] rating: 1.2 (winrate: 52% pickrate: 7%)Underlord
* Heroes with long cast animations can be continuously interrupted by Battery Assault:

Razor
[wiki] rating: 1.0 (winrate: 54% pickrate: 6%)Underlord
* 
Static Link greatly reduces Underlord damage, while benefits Razor himself, even when in Atrophy Aura's range.
* Underlord is a slow and low mobility hero, and cannot outrun Razor's high movement speed, easily for Razor to absorb his damage with Static Link to the maximum and burst him down from the bonus damages, combine with the armor reduction from 
Eye of the Storm
Broodmother
[wiki] rating: 1.0 (winrate: 53% 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.
Juggernaut
[wiki] rating: 1.0 (winrate: 52% pickrate: 19%)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.
Underlord
* In general, heroes with spell immunity abilities won't be caught inside by Pit of Malice: Juggernaut, 
Lifestealer.
Underlord
* Heroes with abilities that can save teammates are also effective such as 
Shadow Demon, 
Dazzle, 
Oracle, 
Bane, 
Pugna, 
Tusk, 
Winter Wyvern, 
Io, Underlord, Treant Protector and 
Keeper of the Light.
Monkey King
[wiki] rating: 1.0 (winrate: 50% pickrate: 16%)Underlord
* 
Firestorm will do little percentage damage to a small HP hero like Monkey King.
* All aspects of Jingu Mastery benefits ignore 
Atrophy Aura's base damage reduction.
* Monkey King can get on top of Underlord easily at any stage of the game.
Disruptor
[wiki] rating: 1.0 (winrate: 49% pickrate: 9%)Underlord
* 
Glimpse will return Underlord or any of his teammates attempting to escape with Dark Rift if timed correctly.

Static Storm and 
Kinetic Field, preventing him from using his abilities as well as preventing him using Dark Rift to escape
Zeus
[wiki] rating: 1.0 (winrate: 46% pickrate: 8%)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.
Pudge
[wiki] rating: 1.0 (winrate: 46% pickrate: 19%)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.
Lina
[wiki] rating: 1.0 (winrate: 46% pickrate: 9%)Luna
* Lina has very high magic burst damage to use against the low-health-pool Luna. 
Laguna Blade can also be upgraded with 
Aghanim's Scepter to bypass Luna's Black King Bar, making Lina even more of a threat.
Bristleback
[wiki] rating: 1.0 (winrate: 46% pickrate: 8%)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.
Kunkka
[wiki] rating: 1.0 (winrate: 44% pickrate: 3%)Underlord
* 
X Marks the Spot will return Underlord or his teammate if they escape with Dark Rift.

[wiki] rating: 0.6 (winrate: 54% pickrate: 2%)Luna
* Heroes that create illusions (such as

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).
Shadow Shaman
[wiki] rating: 0.6 (winrate: 52% pickrate: 16%)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.
Chaos Knight
[wiki] rating: 0.6 (winrate: 52% 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.

Hoodwink
[wiki] rating: 0.6 (winrate: 52% pickrate: 15%)Underlord
* 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%)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.
Mirana
[wiki] rating: 0.6 (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.

Storm Spirit, Weaver.
Necrophos
[wiki] rating: 0.6 (winrate: 50% pickrate: 3%)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.
Underlord
* 
Reaper's Scythe and 
Heartstopper Aura deal percentage-based damage, ignoring Underlord's high health.
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.
Treant Protector
[wiki] rating: 0.6 (winrate: 49% pickrate: 5%)Underlord
* In general, heroes that provide vision will see Dark Rift coming: Techies, Templar Assassin, Treant Protector

* 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.
Grimstroke

[wiki] rating: 0.4 (winrate: 51% pickrate: 10%)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.
Underlord

Timbersaw, 
Axe, Bristleback, 
Alchemist and Underlord
Additional:
* Firestorm is very useful for clearing multiple illusions swiftly.

Bane
[wiki] rating: 0.2 (winrate: 54% pickrate: 3%)Underlord

Disruptor, Death Prophet,

Lich, 
Magnus, 
Mars, 
Medusa, Outworld Destroyer, 
Phoenix, 
Puck, 
Queen of Pain, 
Shadow Fiend, Treant Protector, Underlord, Winter Wyvern,

Morphling, Phantom Assassin, Phantom Lancer, Riki, Shadow Fiend, Slark,

* Luna's Eclipse will often be able to kill Bane before he can even act.
Legion Commander

Additional:
* Atrophy Aura makes it hard for Legion Commander to win 
Duels.
* Dark Rift can be used to save Underlord and his allies from a Duel.
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.
Undying
[wiki] rating: -1.6 (winrate: 50% pickrate: 4%)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.

Dust of Appearance, allowing her to provide vision on him to her team, and possibly, kill Bounty Hunter with Eclipse.

* 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).
Underlord

* Pit of Malice can stop Teleportation channeling.

[wiki] rating: -1.0 (winrate: 47% pickrate: 13%)Luna
* Lucent Beam interrupts Death Ward from a decent range.
* Eclipse kills Witch Doctor during Death Ward, even through 
Glimmer Cape.
Queen of Pain
[wiki] rating: -1.0 (winrate: 47% 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.

Omniknight
[wiki] rating: -1.0 (winrate: 47% pickrate: 1%)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.

* Firestorm and Pit of Malice are very disruptive in team fights, completely matching Mars especially since it can all be cast inside Arena Of Blood and also does percentage-based magical damage, negating Bulwark.
* Dark Rift can save any allies of Underlord trapped in Arena Of Blood.
* Atrophy Aura allows Underlord to lane against Mars quite well since he does not have the best base damage during the early game.
* Underlord is a common carrier of both Pipe of Insight and 
Mekansm/
Guardian Greaves, allowing his team to combat Mars in the mid to late game.
Lifestealer
[wiki] rating: -0.4 (winrate: 48% pickrate: 5%)Underlord
* In general, heroes with spell immunity abilities won't be caught inside by Pit of Malice: Juggernaut, Lifestealer.
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.
Tidehunter
[wiki] rating: -0.4 (winrate: 50% pickrate: 10%)Luna
* Heroes that rely on base damage: Luna, Phantom Lancer are easily countered with Anchor Smash.
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.
Templar Assassin
[wiki] rating: -0.4 (winrate: 51% pickrate: 5%)Underlord
* In general, heroes that provide vision will see Dark Rift coming: Techies, Templar Assassin, Treant Protector
Underlord
* Firestorm will destroy 
Refraction charges very quickly.
* Firestorm will hit Templar Assassin while 
Melded.
* Templar Assassin has a hard time maneuvering around Pit of Malice.
Arc Warden
[wiki] rating: -0.4 (winrate: 54% 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
* 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.
Slark
[wiki] rating: -0.2 (winrate: 48% pickrate: 13%)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.
Underlord
* Heroes with AoE abilities will hit Slark in Shadow Dance: Lina, Jakiro, Underlord, Leshrac, Dark Seer, 
Earthshaker, Timbersaw, Crystal Maiden
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.
Sven
[wiki] rating: 0.0 (winrate: 43% pickrate: 1%)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.
Underlord
* 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.
Doom
[wiki] rating: 0.0 (winrate: 44% pickrate: 2%)Underlord
* An Aghanim's Scepter upgraded 
Doom can be useful against heroes with troublesome passive skills while also disabling them for a long time: Phantom Assassin, Enchantress, 
Huskar, Underlord.
Additional:
* 
Infernal Blade does damage based on percentage health, and is useful against high health pool hero like Underlord
* Doom can prevent Underlord from spamming his abilities and most important is prevent him from using Dark Rift to escape
Underlord
* 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.
Shadow Fiend
[wiki] rating: 0.0 (winrate: 46% pickrate: 18%)Underlord
* Shadow Fiend can still dish out heavy damage with 
Requiem of Souls and 
Shadowraze while caught in Pit of Malice.
Luna
* Lucent Beam and Eclipse with ministun talent can be used to cancel Requiem of Souls if Shadow Fiend does not have Black King Bar.
* Moon Glaives and Lunar Blessing allow Luna to outfarm Shadow Fiend in lane.
* A well timed Eclipse will burst and kill Shadow Fiend before he even gets a chance to retaliate, especially when equipped with Aghanim's Scepter and 
Ethereal Blade, this could become even worse for Shadow Fiend if he does not have Black King Bar.
* Even though Shadow Fiend can evade all of Luna's abilities with Shadow Blade, a smart Luna will always buy Dust of Appearance to provide vision on Shadow Fiend to her and her team.
Terrorblade
[wiki] rating: 0.0 (winrate: 46% 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
* Heroes that can stall pushes: Invoker, Keeper of the Light, Lina, Luna.
Drow Ranger
[wiki] rating: 0.0 (winrate: 47% pickrate: 4%)Luna
* Every hero that can withstand or prevent Eclipse at level 7: Juggernaut, Riki, Clockwerk, Drow Ranger, Abaddon, Faceless Void, Weaver, Outworld Destroyer.
Underlord
* Underlord can not only cancel Marksmanship's aura, but his Atrophy Aura also decreases Drow Ranger's attack damage.
Additional:
* Atrophy Aura reduces Drow Ranger's damage significantly, as she relies on agility.
Winter Wyvern
[wiki] rating: 0.0 (winrate: 49% pickrate: 7%)Underlord
* 
Winter's Curse and 
Splinter Blast can devastate Underlord's team when they're grouped up for Dark Rift.
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.
Additional:
* 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.
Io
[wiki] rating: 0.0 (winrate: 51% pickrate: 7%)Underlord
* Io can escape from Pit of Malice with Tether or Relocate.
* Relocate can counter Dark Rift's split pushing.
Luna
* Lucent Beam can cancel Tether and Relocate.
* Moon Glaives and Eclipse make short work of Io and its tethered ally.
Tinker
[wiki] rating: 0.0 (winrate: 54% pickrate: 12%)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.
Underlord
* All of Underlord's abilities are useful for Rubick to
Spell Steal.
Luna
*
Lucent Beam is a solid magic nuke.
Eclipse can cause massive damage if cast in the right time.
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.
*
* Rubick has a good chance to steal Eclipse for Luna has only two cast abilities.
