* Drow has a very low health pool, allowing Lion to burst her down.
* Drow has no innate escape mechanism, making her an easy target for Lion's disables.
* Lion should be wary of Drow's Gust however, as he has no natural means to deal with it.

* Spectre can easily close the distance on Drow Ranger with Haunt and stick on her with Spectral Dagger, effectively disables her Marksmanship.
* Spectre does not care if silenced by Gust, since Spectre will catch her up regardless.
* Dispersion can reflect some damage back to Drow Ranger should she chooses to attack.
* Be careful once she got her Silver Edge as an attempt to shut you down.

* Black King Bar is useless for Phantom Assassin against Spectre, since all of the Spectre's abilities go through spell immunity,
* Blur cannot evade Desolate because its damage is a separate damage instance and is applied before the attack hits.
* Spectre's high durability provided by Dispersion and damage block items makes her one of the hardest carries to take down.
Additional:
* Dispersion makes it hard for Phantom Assassin to burst down Spectre while also reflecting back Phantom Assassin's high burst damage against herself.
* Desolate ignores the evasion from Blur.
* Black King Bar is useless against Spectre as all of her skills pierce spell immunity.

* Despite her high mobility, Hex or Earth Spike can lock Phantom Assassin down and make her vulnerable.
* Although she has high evasion through Blur, Phantom Assassin has a rather low health pool, making her weak to Lion's magical burst.
Additional:
* Hex and Earth Spike's fast cast animations easily catches Phantom Assassin when she jumps in to attack.
* Finger of Death often ends Phantom Assassin before she can do anything in the early to mid game.

* Finger of Death can instantly shred many targets especially fragile Heroes like Keeper of the Light, Ancient Apparition, or Bounty Hunter.

* Spectre can instantly reveal Bounty Hunter's position on the activation of her ultimate Haunt. She can also semi-reveal( visible but not target-able) Bounty Hunter by hitting him with Spectral Dagger.

* As Ancient Apparition likes to stay far away from the fight to get full effectiveness from Ice Blast, he is a very good target for a Haunt gank.
* Ancient Apparition also has no hard disables and escape spells, making him an easy kill for Spectre.

* Finger of Death can instantly shred many targets especially fragile Heroes like Keeper of the Light, Ancient Apparition, or Bounty Hunter.

* Lion's disables are also really effective against channeling Heroes, like Enigma or Crystal Maiden.

* Haunt can ruin Enigma's initiation with Blink Dagger, no matter where he is on the map.
* Dispersion reflects the damage of Midnight Pulse and Black Hole inflicted back to Enigma.

* Spectre can instantly escape Focus Fire or hunt a Windranger with Haunt.
* Spectre can catch up to her with Spectral Dagger, even if she uses Windrun.
* Desolate allows Spectre to hit Windranger through Windrun.
* Dispersion makes Spectre tanky and also reflects some damage back to Windranger.
Additional:
* Spectre can catch up to her with Spectral Dagger, even if she uses Windrun.
* Spectre can instantly reach a ratting Windranger with Haunt.
* Windrun's miss chance is countered by Desolate.
* Dispersion can reflect some of her damage, especially from her Focus Fire.

* Since Windranger is bad against magical damage, heroes with continuous magical damage or magical nukes can blast her: Zeus, Tinker, Leshrac, Viper, Skywrath Mage, Lion, Lina, Venomancer.

* Ranged heroes that can easily harass Axe: Drow Ranger, Sniper, Lion.

* Dispersion makes Spectre very durable, making it much less likely for Axe to bring her low enough for Culling Blade.
* Spectre can simply use Spectral Dagger to escape against an Axe gank.

* Spectre can instantly escape Burning Army or hunt Clinkz with Haunt.
* Spectre can catch up to him with Spectral Dagger, even if he uses Skeleton Walk.
* Desolate allows Spectre to hit Clinkz through Skeleton Walk.
* Dispersion makes Spectre tanky and also reflects some damage back to Clinkz.
Additional:
* Spectre can catch Clinkz with Spectral Dagger, even if he uses Skeleton Walk.
* Spectre can instantly reach a ratting Clinkz with Haunt.
* Desolate's damage will melt him quickly, as he's alone most of the time.

* Hex and Earth Spike can hold Clinkz down, giving him no chance to use Black King Bar or Skeleton Walk.
* Finger of Death quickly kills Clinkz due to his low health.

* Spectre's entire ability set is designed to get to and destroy heroes that stay in the backlines, both carries (like the aforementioned Drow Ranger and Sniper) and supports (like Dazzle and Shadow Shaman).

* Heroes with high burst damage through their physical attacks or spells can kill Dazzle or his allies before he has a chance to use Shallow Grave. (Lina, Lion, etc.)

* Both Hex and Mana Drain destroy Naga Siren's illusions in an instant, making it hard to teamfight or push against a team with Lion. If Lion chooses the AoE effect talent for Hex or the shard for multi-target Mana Drain, it can negate her pushing potential entirely.
* Earth Spike is an AoE disable with good damage. If used well, it can help distinguish the true Naga Siren by the damage they take (illusions take more damage).

* Mana Drain rapidly saps Morphling's already low mana pool, making him unable to use Waveform or Adaptive Strike. Additionally, Hex prevents these abilities as well.
* An Earth Spike and Finger of Death combo can burst an unwary Morphling down if he has his strength fully shifted to agility.

* Hex's instant cast time will force Brewmaster into the awkward situation of needing some form of spell immunity or block to prevent being immediately hex upon blinking in, or wait until Lion has used all his crowd control before entering a fight. His direct magic burst also makes Brewmaster's Drunken Brawler worthless versus Lion.

* Mana Drain is a headache for Bristleback to deal with during the laning stage, as it denies him the ability to get last hits with Quill Spray.
* Finger of Death deals high damage to Bristleback, and only triggers his passive once.

* Nature's Prophet can literally do nothing against Spectre, because she can chase him from anywhere with Haunt.
* Spectre, just like Naga Siren, loves buying Radiance, which can kill Nature's Prophet's treants, and grant her farm simultaneously.
Additional:
* Spectre can get to him anywhere on the map with Haunt.
* Spectre can pass through his trees with Spectral Dagger.
* Desolate's damage will melt him quickly, as he's alone most of the time.

* As Crystal Maiden is squishy with very bad movement speed, Spectre can easily stay on Crystal Maiden with Haunt and Spectral Dagger.
* Late game, with enough farm, Spectre can withstand an entire Freezing Field, possibly even causing Crystal Maiden to kill herself from Dispersion.

* Lion's disables are also really effective against channeling Heroes, like Enigma or Crystal Maiden.

* Lion will continuously Mana Drain Tiny, depleting his small mana pool for his abilities.
* Hex will keep Tiny from using his high damage spells and attack damage.

* Hex greatly reduces Timbersaw's mobility.
* In addition, Lion can follow up with his Earth Spike and Mana Drain combo, preventing Timbersaw to escape with Timber Chain. And he can finish Timbersaw off with Finger of Death if the latter's HP is low enough.

* Spectral Dagger hinders Sven's low movement speed, and can be an easy tool to escape against his high damage.
* Dispersion makes it harder for Sven to burst down Spectre in one on one fights, and can reflect Sven's high damage back to him or his nearby teammates.
* Haunt and Radiance disables Sven's Blink Dagger.
* Desolate's pure damage ignores Sven's high armor.
* Spectre should not attempt to stand up to a full slotted Sven, since she will get shredded.

* Haunt instantly allows her to get up and close with Sniper, and Spectral Dagger makes it difficult to escape from her.
* Spectre outcarries Sniper in the late game, so Sniper must try to end the game early before Spectre comes online.
Additional:
* Spectre can reach him easily in the backlines with Spectral Dagger or teleport to him with Haunt.
* He is usually a fair distance away from his allies, so Desolate will quickly tear Sniper down.
* Dispersion reflect or reduce his damage, making her hard to take down even at late game.

* Spectral Dagger can be used to traverse past Fissure.
* Haunt will usually disable Earthshaker's Blink Dagger prior to a teamfight, preventing him from initiating.
* On the other hand, Haunt will amplify damage done from Echo Slam. Use this to your advantage.
Additional:
* Spectre can use Haunt to intercept and disrupt Earthshaker's initiation attempts.
* Spectral Dagger can be used to traverse past Fissure.
* Earthshaker often travels alone when he is trying to initiate, so Desolate can be very effective against him.
* Beware that the Haunt illusions amplify the damage done from Echo Slam, which can prove fatal for Spectre's own team.

* With a lot of disables with good range, he might cancel your Echo Stomp.
* Mana Drain can be used to drain Elder Titan's already low mana pool.

* Ember lacks any protection against Lion's disables early in the game and often does not acquire any later, allowing Lion to Hex or Earth Spike him before he escapes through his Fire Remnant.
* Although Flame Guard can prevent magic damage, it does not stop Lion's disables, and Lion can usually break through it with Finger of Death.
Additional:
* Lion possesses two strong disables in Earth Spike and Hex and heavy magic burst with Finger of Death which help lock him down and prevent him from escaping with Activate Fire Remnant. When getting his Blink Dagger Lion can punish Ember Spirit's overextension immediately, or initiate a fight on him with disables.

* Enchantress is very fragile without any form of magic resistance, allowing Lion to easily burst her down.
* Nature's Attendants is a slow heal, making it ineffective against Lion's burst.
* Enchantress lacks any escape mechanism apart from her raw movement speed, allowing Lion to disable her.
* Since Lion's damage comes mostly from his skills, Untouchable does nothing to mitigate it.

* Oracle's burst damage is not enough to take down Spectre due to Dispersion.
* Disarm from Fate's Edict does not hinder Spectre that much, since she can deal damage even without landing a single attack.
Additional:
* Oracle's burst damage is ineffective against Dispersion.
* Disarm provided by Fate's Edict is not as significant debilitation for Spectre as it might be for other carries since She can do damage even without landing attacks.

* Heroes with long disables, like Lion, Night Stalker, or Legion Commander, can prevent Oracle from using spells or items.

* Spectral Dagger and Haunt allow Spectre to get close to Lina.
* Desolate is very strong against Lina, who's usually a bit isolated in fights because of her high attack and cast range.
* Dispersion can mitigate a good portion of Lina's burst damage, allowing Spectre to turn on her afterwards.
Additional:
* Spectre can very easily close the distance on Lina with Haunt and Spectral Dagger, and due to Lina's abysmal mobility without a Blink Dagger and terrible health pool and armor, Lina easily gets slaughtered due Desolate.
* Dispersion can mitigate a good portion of Lina's burst damage, allowing Spectre to turn against her afterwards.

* Spectre can use Haunt to intercept and disrupt Magnus's initiation attempts.
* Spectral Dagger can severely slow down Magnus after he uses Skewer.
* Magnus often travels alone when he is trying to initiate, so Desolate can be very effective against him.
* In late game, Spectre can survive Reverse Polarity initiation thanks to Dispersion.
Additional:
* Spectre disables Magnus' Blink Dagger using her ultimate, and later into the game can usually outlive Reverse Polarity's duration.

* Lion has two low cast point disables (Hex and Earth Spike) to control Ursa before he buys a Black King Bar.
* Hex is one of the few abilities that cannot be dispelled even with an Aghanim's Scepter upgraded Enrage.
* Lion can control Ursa's low mana pool via Mana Drain.

* Wraith King has a very low mana pool and depends on it to cast Reincarnation. Mana Drain will render him useless.
* Wraith King has very low mobility, making it easy for Lion to disable and harass him.
Additional:
* While not being able to confront Wraith King by himself, Lion's Mana Drain helps in draining Wraith King's mana, preventing him from reincarnating unless he has his Aghanim's Shard.
* Lion's Earth Spike and Hex provide decent lockdown against Wraith King as well, preventing the latter from benefiting from Vampiric Spirit bonuses.

* Squishy heroes without good escape mechanism: Crystal Maiden, Chen.

* Heroes that can keep Marci for a long time in one place so she can't pursue her targets, like Bane, Lion, Shadow Shaman, Invoker, Disruptor and Kunkka.

* Mana Drain is very effective against heroes that have mana burn abilities such as Anti-Mage, Nyx Assassin and Keeper of the Light.

* Medusa lacks mobility or escape mechanisms. Earth Spike and Hex can neutralize her strong damage potential and allow for Lion's team to focus her down.
* In addition to easily breaking her commonly bought Linken's Sphere with its low cooldown, Mana Drain can quickly drain her Mana Shield, making her far less tanky.

* Heroes that build Diffusal Blade or can fit it well into their item build will also make Medusa much less tanky: Riki, Naga Siren, Terrorblade, Juggernaut, Spectre, Slark,Drow Ranger.

* Mana Drain depletes Nercophos' mana pool, preventing him from using his abilities.
* Finger of Death deals high magical damage, which becomes amplified by Ghost Shroud.

* Enemies that possess high defenses through magic resistance, damage reduction, or high regeneration will make it difficult to whittle their health down to get to Reaper's Scythe's threshold. Such heroes include Bristleback (although only from behind), Spectre, Ursa, and Dragon Knight.

* Heroes with high burst damage: Lina, Lion, Luna, Nyx Assassin, Queen of Pain.

* One of Lion's level 20 talents lets Mana Drain affect 2 secondary targets. This can make things difficult for heroes like Phantom Lancer, Chaos Knight, and Terrorblade who rely on illusion armies.
* Mana Drain and Hex instantly kill any illusions. Finger of Death upgraded with Aghanim's Scepter also shreds most illusions.
* One of Lion's level 20 talents lets Mana Drain affect 2 secondary targets. This can make things difficult for heroes like Phantom Lancer, Chaos Knight, and Terrorblade who rely on illusion armies.

* Heroes that can kill Death Prophet with nukes can prevent her from using Exorcism to its full duration or using it at all: Lina, Lion, Puck, Morphling.

* Heroes with forced movement spells or non-interrupting forced movement, such as Lion, Drow Ranger, Magnus, Mars, as they can cancel blast-off mid air in lane, removing his ability to deny himself and output damage.

* Heroes with high magical burst damage will kill Gyrocopter before he gets to do much: Lina, Lion, Zeus

* Heroes with high magical burst can easily kill Huskar when he is at low health: Lion, Lina, Skywrath Mage

* High priority targets like Queen of Pain, Drow Ranger and even Anti-Mage can't get caught out from Lion's long range disables.

* Mana Drain has an extremely long range and low cooldown. It can easily deplete most heroes of their entire mana pools, especially those with smaller mana pools such as Tiny or Spirit Breaker.

* His global teleportation with Boots of Travel and Rearm is easily countered with Haunt, and Spectre can reach him anywhere on the map.
* He is squishy, and if alone Desolate will kill him very fast.
* Laser's blind isn't reliable, since Desolate cannot miss. Even worse, Dispersion can reflect and reduce his burst damage.

* Although Weaver can potentially Time Lapse out of any burst, Weaver has a fragile health pool, and Lion's disables can kill him before.
* Weaver is very mana dependent and has a rather small mana pool in the beginning of the game. Mana Drain can deplete him of mana and lessen his early game presence.
* Earth Spike can be point targeted and hits through Shukuchi to make him vulnerable.
* Linken's Sphere is easily broken by targeted spells with low cooldown.

* All of Lion's abilities are active making Demonic Purge break from Aghanim's Scepter useless.
* Hex and Mana Drain can make quick work of whatever illusions you're creating, especially when he acquires his Talents at level 20 and 25.
* An attempt to save an ally using Disruption can easily become a perfect setup for a Earth Spike or Finger of Death with Aghanim's Scepter for the enemy.

* None of Spectre's spells are very good for Rubick to Spell Steal.

* Spectral Dagger follows Riki even after he goes invisible and stays on him through Tricks of the Trade, revealing his location.
* Desolate grants Spectre the ability to damage Riki with right clicks regardless of Smoke Screen's blind.
* Riki relies on his high damage to kill is opponents, which is countered by Dispersion.
* Haunt can find Riki globally at any time, negating much of his ganking potential.

* Heroes with silences and hard stuns such as Doom, Silencer, and Lion can keep Mirana from Leaping away.

* If Meepo ganks Lion with Poof and Earthbind, he will be an easy target for Earth Spike & AoE Hex from his level 25 talent.

* Heroes that create illusions: 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, 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, but that will require lots of farming for right-click items.

* Heroes with long or multiple disables will prevent Legion Commander from winning Duels: Shadow Shaman, Lion

* 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.

Additional:
* Zeus burst damage can be reduced by Dispersion and reflect some of the damage back to Zeus himself.
* Zeus has low mobility and stays in backlines, Spectral Dagger or Haunt can easily catch him as he has no escape mechanism.
* Since Zeus has low HP, Spectral Dagger and Desolate will quickly tear Zeus down when he's alone.
