* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, Storm Spirit, Ember Spirit, Lycan, Bloodseeker, Anti-Mage, Timbersaw.

* Melee heroes that get kited easily have hard times dealing with Puck without any lockdowns, as Puck is one of the most mobile heroes. Heroes like Sven, Lifestealer, Ursa and Alchemist may have problems to get to Puck without proper initiation items. They also lack reliable lockdowns, as their disables are easily avoidable for Puck, or are just a soft disable.

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

* Nyx Assassin can reflect Life Break with Spiked Carapace.

* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, Storm Spirit, Ember Spirit, Lycan, Bloodseeker, Anti-Mage, Timbersaw.

* Nyx Assassin might not kill Abaddon with his nuke, but a support Abaddon will struggle to protect an ally from him.

* Heroes that have disposable area-targeted spells can force her to undo her Meld: Leshrac, Puck, Tiny, Jakiro,. An experienced Templar Assassin could try to use Refraction before Meld so she can tank through those damage without getting her Blink disabled.

* Illusory Orb and Phase Shift allows Puck to avoid most ganking attempts.
* Waning Rift and Dream Coil makes it very hard for Slark to escape bad situations.
* Puck's abilities used together also deals significant magical nuke damage, none of which are targeted and thus cannot be avoided by Shadow Dance.

* All of Puck's damaging spells deal AoE magic damage, which focuses on Terrorblade's low health pool and ignores his armor.
* Puck's spells are also great at quickly clearing all of Terrorblade's illusions. Even a single Illusory Orb is enough to drop their health very low, allowing creeps, towers or allies to finish them off very quickly. Waning Rift and Illusory Orb together are usually enough to clear his illusions.
* Waning Rift prevents Terrorblade from casting Sunder at low health.
* Puck is a common Dagon carrier, making it possible to finish off Terrorblade before he has a chance to Sunder.

* Nyx Assassin deals large amounts of pure damage with Vendetta and magical damage with Impale and Mind Flare, allowing him to ignore Terrorblade's armor and burst his low health pool down before he can use Sunder.
* Nyx Assassin commonly buys Urn of Shadows, Dagon and Meteor Hammer which deal magic damage that ignore Terrorblade's armor.

* All of Puck's abilities are area-targeted, and will hit Dark Willow when she uses Shadow Realm.
* Illusory Orb allows Puck to bypass Bramble Maze, close the gap and silence Dark Willow with Waning Rift.
* Phase Shift helps Puck dodge attacks charged by Shadow Realm, and is easily timed against Terrorize's long cast time.

* Nyx Assassin's high burst damage can be the bane of Dark Willow, as her low health makes it difficult to survive long enough to escape through Shadow Realm.
* Spiked Carapace can be triggered by walking deliberately into Bramble Maze, leaving Dark Willow stunned and defenseless.

* Dream Coil leash can stop and stunned moving from Windrun.
* Combinated Wanning Rift and build Blink Dagger can easily avoid from Focus Fire

* Many of Nyx Assassin's abilities are good against Windranger.
* Impale is great for stunning Windranger and allowing additional disables to be landed.
* Mind Flare is useful against Windranger's decent intelligence growth.
* Spiked Carapace is easy to use against Powershot.
* Vendetta allows Nyx Assassin to sneak up on and deal massive damage to Windranger without giving Windranger a chance to use Windrun to evade it.
* Nyx Assassin's item build allows him to easily deal with Windranger.

* Sniper has no spells to disable Puck. He lacks a silence to prevent spell casting and a stun to disable, allowing Puck to act instantly against Sniper.
* Sniper's main strategy is to attack his enemies from safe distance. Illusory Orb, combined with Blink Dagger makes it easy for Puck to get to Sniper. Due to his low health, he is also easily nuked down by Puck.
* The status debuff placed by Assassinate on its target makes it very easy to avoid it. Puck has 2 (3 when having Blink Dagger, 4 when having Eul's Scepter of Divinity, 5 when having Linken's Sphere) methods to disjoint or dodge the projectile, making it a bad spell for finishing off Puck.

* Assassinate is easy to reflect with Spiked Carapace for massive damage.
* Shrapnel's area damage can set up an easy stun with Spiked Carapace, especially when combined with Vendetta.
* In the early game, Sniper's low health pool and high intelligence makes him easy prey for Nyx Assassin.

* Puck Outlanes Invoker with his abilities: Illusory Orb, Waning Rift finishing off all creeps on the line and getting a higher level than him
* Puck dodges Invoker's magic attacks with his abilities: Illusory Orb, Phase Shift in a fight, preventing Invoker from doing damage
Additional:
* Puck Outlanes Invoker with his abilities: Illusory Orb, Waning Rift finishing off all creeps on the line and getting a higher level than him
* Puck dodges Invoker's magic attacks with his abilities: Illusory Orb, Phase Shift in a fight, preventing Invoker from doing damage

* Nyx Assassin can simply activate Spiked Carapace while under many Invoker's abilities to stun him.
* Nyx Assassin takes advantage of Invoker's massive intelligence gain to do tons of damage using Mind Flare, as the spell does more damage based on the target's intelligence.
* Vendetta burns a large amount of Invoker's essential mana pool.

* Although Phoenix has many ways to disable a Blink Dagger, the high cooldown of all of its spells makes them not as reliable for this. Also, its spells cost a lot of health to use, making it easy to get nuked down.
* Waning Rift prevents Phoenix from using Supernova to refresh itself, giving Puck's team time to finish it off, or allow Puck to burst Phoenix down.
* Dream Coil prevents Phoenix from using Icarus Dive without consequences. Waning Rift and Dream Coil are also able to cancel Sun Ray, which is its main source of damage in the late game.

* Spiked Carapace reacts on any of the damage over time from Phoenix's abilities and can interrupt Sun Ray and Icarus Dive.

* Puck easily dodges the Nether Blast and the Pugna Life Drain with his Phase Shift, which is why he can easily avoid his strong magic damage
* The Puck's silence from the Waning Rift ability allows her team to easily cope with the Pugna, which cannot be said about the Pugna, because with the Puck it will be easy to avoid such an attack from the Decrepify
* The Puck's combo: Waning Rift + Illusory Orb + Dream Coil doesn't have a huge amount of damage to feel the damage of the Pugna from Nether Ward, however, it may be quite enough to kill the Pugna solo at an early stage of the game with Witch Blade
Additional:
* Puck easily dodges the Nether Blast and the Pugna Life Drain with his Phase Shift, which is why he can easily avoid his strong magic damage
* The Puck's silence from the Waning Rift ability allows her team to easily cope with the Pugna, which cannot be said about the Pugna, because with the Puck it will be easy to avoid such an attack from the Decrepify
* The Puck's combo: Waning Rift + Illusory Orb + Dream Coil doesn't have a huge amount of damage to feel the damage of the Pugna from Nether Ward, however, it may be quite enough to kill the Pugna solo at an early stage of the game with Witch Blade

* Due to Pugna's incredible intelligence growth and terrible strength growth, Nyx should always be able to take you out with his combo, with or without an added Dagon. Mind Flare will deal a large amount of damage in particular, especially in the late game.
* Spiked Carapace is also a great tool versus Pugna. A good player will wait for you in Vendetta until you farm a creep wave with Nether Blast and reflect it back at you as their initiation and setup for Impale.
Additional:
* Nether Blast's animation makes it easy to time Spiked Carapace for a stun.
* Pugna has the largest intelligence gain in the game, making him a prime target for Mana Burn.
* Pugna needs to channel Life Drain, making him easy to hit with Impale.

* Puck relies mainly on magical burst damage, which Phantom Assassin is most vulnerable against.
* Phase Shift and Illusory Orb disjoint Stifling Dagger, also allowing to kite Phantom Assassin.
* Dream Coil will stun Phantom Assassin if she uses Phantom Strike to blink away.

* Heroes with heavy early and mid-game magical damage are also problematic for Phantom Assassin due to being able to easily kill her before she can gain an item advantage over them: Lina, Necrophos, Nyx Assassin, Gyrocopter.

* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, Storm Spirit, Ember Spirit, Lycan, Bloodseeker, Anti-Mage, Timbersaw.

* Vendetta is capable of removing most of Storm Spirit's large mana pool, along with dealing heavy damage and quickly depleting his chances of escaping a gank or fight.
Additional:
* Mana Burn removes much-needed mana for Ball Lightning.
* Spiked Carapace triggers on Static Remnant for an easy stun.

* Because all of Warlock's abilities are active abilities, silences can make his impact in fights minimal. Be cautious of heroes that carry silences like Death Prophet, Puck, and the aforementioned Silencer.

* Impale and Spiked Carapace interrupts Upheaval with ease.
* Warlock's low health pool, mobility, and high intelligence gain makes him a prime target for Nyx Assassin's burst damage.

* Low health spellcasters: Lina, Witch Doctor, Tinker, Keeper of the Light, all rely heavily on their spells and are fragile heroes. They all also have avoidable spells, allowing Puck to get to them and quickly burst them down.

* Nyx Assassin's whole skillset is good against Tinker:
* Impale prevents Tinker from blinding Nyx Assassin or fighting back, while giving Nyx' allies time to catch up to Tinker's position.
* Mind Flare generally deals more damage to intelligence based heroes like Tinker.
* Spiked Carapace can stun Tinker at a moment of Nyx Assassin's choosing if March of the Machines has been cast. It is also quite easy to time Spiked Carapace against Heat Seeking Missiles.
* Vendetta allows Nyx to approach Tinker in the trees or wait for him in common hiding spots and deal heavy damage to his low armor.
Additional:
* Heat-Seeking Missile allow easy Spiked Carapace stuns.
* As a fragile hero that relies on mana and intelligence items, Tinker is vulnerable to Mana Burn.
* Nyx Assassin's stuns can interrupt Rearm and leave Tinker helpless.

* Puck has both Waning Rift and Dream Coil to stop Freezing Field's channel regardless of whether or not Crystal Maiden has a Glimmer Cape, as both spells fully affect invisible units.

* Crystal Maiden has a very bad movement speed, so Impale is easy to land against her. Furthermore, even while trapped by Frostbite, Nyx Assassin can still cast Impale.
* Crystal Maiden has very low armor, so Vendetta is very effective.
* Nyx Assassin has two ways to stop Freezing Field, provided she doesn't get a Black King Bar. He can either pop Spiked Carapace and simply walk into the field, or he can use Impale to interrupt the field, since Crystal Maiden has to channel it.
Additional:
* Spiked Carapace easily interrupts Freezing Field.
* Frostbite's damage over time sets up an easy Spiked Carapace stun.
* Crystal Maiden is extremely fragile and dies quickly to Nyx Assassin's burst damage.

* Puck dodges the abilities of Lina Dragon Slave and Light Strike Array with his Phase Shift skill, which helps him avoid combining these abilities with Laguna Blade and avoid burst damage from Lina
* Puck forbids Lina to use her abilities with the Waning Rift ability, which will help her teammates survive and even give them the opportunity to kill her
Additional:
* Puck dodges the abilities of Lina Dragon Slave and Light Strike Array with his Phase Shift skill, which helps him avoid combining these abilities with Laguna Blade and avoid burst damage from Lina
* Puck forbids Lina to use her abilities with the Waning Rift ability, which will help her teammates survive and even give them the opportunity to kill her

* Mind Flare does tons of damage against Lina because of her high intelligence.
* The mana burn from Vendetta also prevents Lina from casting her full combo.
* Spiked Carapace can easily be used to counter Lina's abilities because of their long cast animation, and could probably kill Lina outright if Laguna Blade is reflected.

* Heroes that are hard to kill without lockdown: Puck, Weaver.

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

* Mass summoning heroes: Broodmother, Nature's Prophet and Enigma all have summons Puck can clear clear with Illusory Orb and Waning Rift instantly, due to their summons having low health.

* Heroes with invisibility: (Riki, Clinkz, Nyx Assassin.

* Nyx can walk into Firefly with Spiked Carapace and stun Batrider if he has no Spell Immunity, even if Batrider is focusing on other enemy hero.

* Vendetta can deal great damage against her. However, it requires an direct attack, so Nyx Assassin may have difficulties applying Vendetta on her.
* Enchantress's lack of mobility makes her a primary target for ganking with Vendetta.
* Mind Flare can deal a great damage against her due to being an Intelligence hero.
* Spiked Carapace can reflect Impetus and stun Enchantress.
Additional:
* Spiked Carapace reflects the damage from Impetus.
* Enchantress is a rather squishy hero, making her fall easily to Nyx Assassin's high burst damage.

* Spiked Carapace stops Snapfire's Mortimer Kisses.

* Dream Coil and Wanning Rift prevent Pangolier from using Swashbuckle and Rolling Thunder. If Puck has Aghanim's Scepter, Dream coil will stop Rolling Thunder from moving entirely.
Additional:
* Illusory Orb and Waning Rift provides great mobility, allowing Puck to catch up Pangolier when he is attempting to disengage with his own skills.
* Dream Coil's leash act almost as a literal silence to Pangolier, disabling half of his arsenal and also piercing his spell immunity during Rolling Thunder. Also Dream Coil's very long duration will make Pangolier wasting his entire ultimate rolling in place.

* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, Storm Spirit, Ember Spirit, Lycan, Bloodseeker, Anti-Mage, Timbersaw.

* Spiked Carapace can be easily triggered by Flame Guard or Battle Fury, setting up a deadly Impale.
Additional:
* With Vendetta, Nyx Assassin can move closely to Ember Spirit when he's farming with his Flame Guard and use Spiked Carapace with Impale to provide a reliable and long disable.

* With her passive Split Shot, Medusa can be easily interrupted by Spiked Carapace during combat, especially during her precious Stone Gaze.
* Mana Burn quickly destroys Mana Shield, especially if Medusa only increases her mana pool by bolstering intelligence (which has the added bonus of increasing Mana Burn's damage).
* Uncontrollable damage from Mystic Snake and Split Shot can trigger Spiked Carapace.
* Medusa lacks single target damage, making a Burrowed Nyx Assassin hard to kill.
Additional:
* Vendetta burns a significant amount of mana on hit, and the damage from the ability drains Medusa's mana pool even further.
* Due to the passive nature of Mystic Snake and Split Shot, it can possibly proc Nyx's Spiked Carapace if he's within range of Medusa's abilities and isn't invisible.
* Medusa lacks single target damage, making Nyx with Aghanim's Scepter extremely hard to deal with if Medusa is the team's main damage source.

* Ravage's travel time allows Nyx Assassin to easily stun Tidehunter with Spiked Carapace.
* Vendetta can instantly deplete Tidehunter's low mana pool, especially in the early game, potentially preventing Tidehunter from casting Ravage.

* Puck can initiate on Mirana with Waning Rift to prevent her from going invisible or Leaping.
* A Mirana caught in Dream Coil will stun herself if she tries to Leap away.
* Puck's Burst damage takes advantage of Mirana's below average health.
* Puck can easily dodge Sacred Arrow and Starstorm with Phase Shift.
Additional:
* Mirana's spells are laid out to assassinate enemies. Puck can easily avoid the slow moving Sacred Arrow, and also can avoid Starstorm with Phase Shift, since the meteors have a delay.
* If Puck casts either Waning Rift or Dream Coil in the area, Mirana cannot Leap away.

* All of Puck's abilities are active making Demonic Purge break from Aghanim's Scepter useless.
* Shadow Demon will find a hard time catching a Puck, as he can get away with Illusory Orb or even Waning Rift;
* Puck can dodge Shadow Poison waves and potentially avoid the damage from Demonic Purge with Phase Shift. Furthermore, after Disruption ended, Puck can use Phase Shift to avoid any further danger and can blink away with Blink Dagger.
* Waning Rift can be used to initiate Shadow Demon, prevent him from using any spells.

* Nyx Assassin has a lot of burst damage from his Impale, Mind Flare, Dagon, and the bonus damage from Vendetta. All of this damage is enough to kill Drow Ranger.
* Nyx Assassin is usually invisible most of the time thanks to his ability Vendetta, which allows him to gank Drow Ranger easily.

* Nyx's Spiked Carapace can reflect the damage of Sharpshooter, instantly killing hoodwink. Nyx can also use Vendetta to position himself in such a way to screen allies from Sharpshooter and catch Hoodwink by surprise.

* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, Storm Spirit, Ember Spirit, Lycan, Bloodseeker, Anti-Mage, Timbersaw.

Additional:
* Puck will make a game of dodging as many Shadow Strikes as he can with Phase Shift. If he's a good player, he will also dodge Sonic Wave. If he's a great player, he will also dodge Scream of Pain. All through a single spell.
* Puck also has a silence to stop her blink with Waning Rift.
* Puck will have vision to hunt her down if she blinks into the trees with Illusory Orb.
* If Queen of Pain is under the effect of Dream Coil, she will be unable to blink out.

* A good Nyx can reflect Queen of Pain's Sonic Wave with his Spiked Carapace, or even initiate a gank on her in Vendetta while she farms a creep wave with Scream of Pain.
* Her strength to intelligence ratio is bad enough that he should be able to kill her without even requiring a Dagon, provided he can get his full combo off.

* Nyx Assassin's high burst damage, excellent ganking potential and multiple disables pose a threat to Muerta at all stages of the game.
* Mind Flare abuses Muerta's high intelligence to make short work of her low health.
* Spiked Carapace and Vendetta allow Nyx to escape or initiate well against Muerta's low mobility.
* As with most retaliation based abilities, Spiked Carapace can easily take advantage of Gunslinger's stray shots.

* Void Spirit can easily be bursted down by Puck's high magic damage spells in early game.
* Wanning Rift and Dream Coil prevent him from using two of his important mobility abilities: Dissimilate and Astral Step.
Additional:
* Dream Coil prevents the usage of Void Spirit's escape abilities and limits his damage output in fights almost entirely.
* Killing Puck in the late game becomes difficult when they obtain a Eul's Scepter of Divinity, Blink Dagger, and Phase Shift.

* Nyx Assassin's Spiked Carapace will stun Leshrac when hit by any of his AOE abilities.
* Mind Flare deals high damage due to Leshrac's high intelligence gain.
* Vendetta burns a large amount of Leshrac's essential mana pool.

* Spiked Carapace allows Nyx to get an easy long-duration stun on Weaver once he uses Shukuchi, and then he can follow up with Impale.
* Vendetta works as a great setup for both Impale and Spiked Carapace and can deal decent damage to Weaver. Additionally he can neutralize The Swarm beetles due to his invisibility duration.

* Vendetta disables Vengeance Aura and allows him to attack Vengeful Spirit with Impale and Mind Flare.
* Spiked Carapace is easy to use against a Wave of Terror or Magic Missile.

* Phase Shift can easily disjoint Phantom Embrace and waste half of the Soulbind's duration.
* Puck is very mobile hero who can jump backsides and burst Grimstroke before he can cast anything.

* Phase Shift allows Puck to dodge all of Earthshaker's abilites.
* Waning Rift disables Earthshaker's stuns, leaving him and his team vulnerable.
* Dream Coil takes a stun from Earthshaker if he tries to escape from Blink Dagger or Enchant Totem upgraded from Aghanim's Scepter.

* The huge physical damage taken from Vendetta will force Necrophos to use Ghost Shroud, which is good for a followup with Dagon and Ethereal Blade, both of which are common items on Nyx Assassin.
* Using Ghost Shroud also sets Necrophos up for a Mind Flare or Impale.

* Outworld Destroyer's high intelligence makes him a good target for Mind Flare.
* If timed correctly, Spiked Carapace will return the full damage from Sanity's Eclipse back to Outworld Destroyer. Even a reflected Arcane Orb can deal significant damage and make him vulnerable to a follow-up from Nyx Assassin.
* Spiked Carapace is also the perfect tool against Astral Imprisonment: if used on Nyx, he can reflect the damage back as he comes out of the prison by casting the ability while imprisoned.
Additional:
* Outworld Destroyer's high intelligence gain and fragility makes him an easy target for a massive Mana Burn, as well as killing him outwards with Nyx Assassin's high burst damage.
* Astral Imprisonment can be easily exploited by Nyx Assassin with his abilities. As long as Astral Imprisonment was not cast on Nyx Assassin, it will make an opportunity for an easy stun, either by Spiked Carapace (if Outworld Destroyer hid his allies or your allies) or Impale (if he hid himself). If Astral Imprisonment was cast on Nyx Assassin, using Spiked Carapace while banished will proc the stun after the disable, since Spike Carapace has a 0 second cast time and Astral Imprisonment deals damage right after the disable ends.
* An ill-timed Sanity's Eclipse and/or well timed Spiked Carapace can deal a lot of damage to Outworld Destroyer and stun him, unless Outworld Destroyer used Black King Bar beforehand.

* Puck's area of effect nukes in the form of Illusory Orb and Waning Rift clears Phantasm illusions from the early game to mid game.
* Phase Shift can be used to disjoint Chaos Bolt.

* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, Storm Spirit, Ember Spirit, Lycan, Bloodseeker, Anti-Mage, Timbersaw.

* Melee heroes that get kited easily have hard times dealing with Puck without any lockdowns, as Puck is one of the most mobile heroes. Heroes like Sven, Lifestealer, Ursa and Alchemist may have problems to get to Puck without proper initiation items. They also lack reliable lockdowns, as their disables are easily avoidable for Puck, or are just a soft disable.

* Heroes with silencing abilities that are not blocked by Linken's Sphere, like Puck's Waning Rift, Death Prophet's Silence or Silencer's Global Silence.

* 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.

* Puck with Phase Shift
* Heroes that can dodge Glimpse:
* Puck with Phase Shift
* Riki with Tricks of the Trade
* Phantom Lancer with Doppelganger
* Ember Spirit with Sleight of Fist and Activate Fire Remnant
* Chaos Knight with Phantasm
* Naga Siren with Mirror Image
* Tusk with Snowball
* Juggernaut with Omnislash
* Brewmaster with Primal Split
* Lifestealer with Infest
* Phoenix with Supernova

* Heroes that can pick you off: Clinkz, Nyx Assassin, Puck, Riki.

* Melee heroes that get kited easily have hard times dealing with Puck without any lockdowns, as Puck is one of the most mobile heroes. Heroes like Sven, Lifestealer, Ursa and Alchemist may have problems to get to Puck without proper initiation items. They also lack reliable lockdowns, as their disables are easily avoidable for Puck, or are just a soft disable.

* Low health spellcasters: Lina, Witch Doctor, Tinker, Keeper of the Light, all rely heavily on their spells and are fragile heroes. They all also have avoidable spells, allowing Puck to get to them and quickly burst them down.

* Large area-of-effect with delay or require channeling: Enigma, Crystal Maiden, Invoker, Shadow Fiend, Pugna, Keeper of the Light, Dawnbreaker.

Additional:
* Spiked Carapace can be used to reflect Illuminate damage and stun Keeper of the Light.
* Vendetta allows Nyx Assassin to follow Keeper of the Light around if he tries to split-push.
* Keeper of the Light is very squishy and will very quickly die to Vendetta and it's followup abilities.

* Melee heroes that get kited easily have hard times dealing with Puck without any lockdowns, as Puck is one of the most mobile heroes. Heroes like Sven, Lifestealer, Ursa and Alchemist may have problems to get to Puck without proper initiation items. They also lack reliable lockdowns, as their disables are easily avoidable for Puck, or are just a soft disable.

* Like above, supports with reliable stuns can be a massive problem and force Black King Bar in fights unideally, such as Shadow Shaman, Lion, Nyx Assassin.

* Slow-moving projectiles: Skywrath Mage, Tinker, Necrophos

Additional:
* Skywrath Mage's low health makes him rather easy prey for Nyx Assassin and his lack of armor generally means he'll take the full brunt of a Vendetta strike.
* Mind Flare turns Skywrath Mage's high intelligence growth against him and deals heavy damage.
* Spiked Carapace gives Nyx some degree of protection against Skywrath's spells.

* Puck silences Ogre Magi with Waning Rift, and Phase Shift makes Puck untargetable for the duration.

* Heroes that can reliably kite out Dispose, Unleash and dodge Rebound, like Ember Spirit, Void Spirit, Storm Spirit, Anti-Mage, Faceless Void, Puck or always build items like Blink Dagger and Force Staff.

* Heroes with silence and mana drain abilites, as Ancient Apparition relies entirely on his abilities: Invoker, Silencer, Nyx Assassin, Skywrath Mage, Shadow Shaman, Lion and etc.

* 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.

* Heroes with long range abilities are also able to touch Zeus, such as Clockwerk, Kunkka, Puck, Skywrath Mage, Spirit Breaker, Tusk and others.

* Heroes with either magical, physical or pure damage burst: Bane, Ember Spirit, Leshrac, Lina, Luna, Nyx Assassin, Phantom Assassin, Skywrath Mage, Tinker, Ursa, Void Spirit.

* Heroes with either magical, physical or pure damage burst can often kill Chen or his allies before he can use Hand of God: Lina, Luna, Techies, Shadow Fiend, Pugna, Nyx Assassin.

* Heroes with powerful area-of-effect disables can initiate on Meepo and his clones and shut him down, such as Enigma, Invoker, Magnus, Puck, and Sand King.

* Waning Rift silences and damages enemies affected by the ability, diminishing Lion's punishing powers.
* High burst damage potential plus mobility and disable through Illusory Orb, Waning Rift, and Dream Coil allows Puck to effortlessly chase, lock and/or kill Lion, as the Demon Witch lacks proper ways to avoid so.
* Phase Shift allows Puck to dodge Earth Spike, Finger of Death and breaks Mana Drain's link.

* Spiked Carapace interrupts Starbreaker before Dawnbreaker has her Aghanim's Shard, as well as Solar Guardian during the initial channel, making her ineffective at joining and dealing damage in teamfights.
* The slow projectile and damage over time effect of Celestial Hammer makes it easy to stun Dawnbreaker if she attemps to engage or chase.
Additional:
* Spiked Carapace can stop Dawnbreaker's Solar Guardian which will eliminate her global presence and limits her movement around the map.

* Impale and Spiked Carapace can be used to cancel Dismember easily, and can even do so when Pudge uses it on Nyx Assassin, if timed correctly.

* Illusory Orb and Waning Rift are effective nukes against Phantom Lancer's illusions, especially in the early game.
* Dream Coil limits Phantom Rush and Doppelganger's mobility during teamfights.

* Waning Rift silences Anti-Mage, preventing him from blinking away.
* However, Waning Rift can be dispelled by Manta Style.
* Dream Coil stops Anti-Mage from blinking, with Aghanim's Scepter also locks down Anti-Mage for long duration.

* Mass summoning heroes: Broodmother, Nature's Prophet and Enigma all have summons Puck can clear clear with Illusory Orb and Waning Rift instantly, due to their summons having low health.

* Enigma is fragile, and lacks escapes, being dependent on Blink Dagger for mobility. Ganking Heroes or Heroes with burst damage will likely kill him before he can do anything. Such Heroes include: Lina, Lion, Luna, Puck, Slark, Nyx Assassin, etc.

Additional:
* Enigma's uncontrollable damage from Malefice and Midnight Pulse make him easy to stun with Spiked Carapace.
* Black Hole can be easily interrupted by Impale or Spiked Carapace.

* Puck can forbid the opportunity to avoid trouble for Earth Spirit on his own Rolling Boulder, using abilities: Dream Coil, Waning Rift
Additional:
* Puck can forbid the opportunity to avoid trouble for Earth Spirit on his own Rolling Boulder, using abilities: Dream Coil, Waning Rift

* Silencer is rather squishy and has poor mobility without items, making him an easy target for Nyx.
* Silencer's intelligence steal ability is a complete disadvantage against Nyx Assassin as Mind Flare will deal increasing damage for each point of intelligence Silencer has stolen, turning Silencer's intelligence steal against him.
Additional:
* Last Word is extremely easy to reflect with Spiked Carapace for large amounts damage, due to triggering when Nyx Assassin casts a spell, but can still silence Nyx Assassin. It also has the added bonus of dealing more damage the more Intelligence Silencer has.
* Glaives of Wisdom quickly builds Silencer's Intelligence, making him a particularly prime target for Mana Burn.
* Silencer rarely builds survivability items, nor is he able to steal much Intelligence while surrounded by his team, and so is an excellent target for Vendetta.
* Silencer has no reliable way of dealing with a burrowed Nyx, and also lacks the ability to prevent Nyx from escaping with Vendetta,

* Heroes who can drain mana can make Omniknight useless after he uses one or two abilities: Lion, Anti-Mage, Nyx Assassin.

* Low health spellcasters: Lina, Witch Doctor, Tinker, Keeper of the Light, all rely heavily on their spells and are fragile heroes. They all also have avoidable spells, allowing Puck to get to them and quickly burst them down.

* Mass summoning heroes: Broodmother, Nature's Prophet and Enigma all have summons Puck can clear clear with Illusory Orb and Waning Rift instantly, due to their summons having low health.
