Spirit Breaker
* Heroes with summons and illusions as Spirit Breaker has no strong AoE capabilities to deal with them: 
Chaos Knight, 
Phantom Lancer, 
Terrorblade, 
Naga Siren, 
Broodmother, 
Warlock, 
Visage, 
Nature's Prophet, 
Shadow Shaman, 
Lycan, 
Wraith King.
Skywrath Mage
* In the early-mid game, Skywrath consistently needs to use his entire mana pool to kill a hero, but Wraith King's 
Reincarnation allows him to finish off Skywrath after the first death, as Skywrath Mage will have likely expended all his mana.
Spirit Breaker
* Heroes that have a weak laning stage: 
Spectre, 
Nyx Assassin, 
Clockwerk, 
Spirit Breaker, 
Omniknight, 
Pudge.
Skywrath Mage
* Heroes with silence such as 
Riki, 
Silencer, or 
Night Stalker prevents Skywrath Mage from using his spells.
Spirit Breaker
* 
Mana Drain has an fair 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.
Skywrath Mage
* Skywrath's pitiful defences also make him easy meat to heroes with high burst like 
Juggernaut, 
Lion, or 
Phantom Assassin, the latter occasionally downing a support Skywrath in a single 
Stifling Dagger.
Spirit Breaker
* Heroes with summons and illusions as Spirit Breaker has no strong AoE capabilities to deal with them: Chaos Knight, Phantom Lancer, Terrorblade, Naga Siren, Broodmother, Warlock, Visage, Nature's Prophet, Shadow Shaman, Lycan, Wraith King.
Skywrath Mage
* Skywrath Mage also has a terrible time fighting against anything that isn't a hero. His skills are mostly target-based and he has terrible strength and agility, he can easily be kited or harassed by illusion-based heroes like Chaos Knight and Phantom Lancer, or by Heroes that summon other units like 
Lone Druid, Lycan and 
Beastmaster.
Spirit Breaker
* In the early game, Omniknight can look like an easy target for Spirit Breaker, but with 
Purification and 
Hammer of Purity, what could be an opportunity could quickly turn into disaster.
* 
Repel can be used to counter Charge of Darkness by minimizing the damage and lowering the stun duration with status resistance.
* Spirit Breaker's Greater Bash from all sources (Charge of Darkness or normal attacks) will deal no damage at all if Omniknight and his allies are protected with presence.
* Due to this, Spirit Breaker's damage will always be lower when targeting Omniknight.
Skywrath Mage
* Fate Edict can completely negate Skywrath Mage's heavy magic damage.
* Fortune End dispels 
Ancient Seal.
Spirit Breaker
* If Medusa activates 
Stone Gaze before Spirit Breaker reaches her with Charge of Darkness, the charge will inevitably fail.
* Medusa has three ways to counter Spirit Breaker's Charge of Darkness: Stone Gaze can disable Spirit Breaker's Charge of Darkness if he faces Medusa directly. 
Aghanim's Scepter upgraded 
Mystic Snake can disable Spirit Breaker and cancel his Charge of Darkness if it hits him. And 
Cold Blooded provided by 
Aghanim's Shard that can cast a single-targeted Mystic Snake at Spirit Breaker if he uses Charge of Darkness on her.
* 
Mana Shield and overall tankiness allows Medusa to easily survive Spirit Breaker's initiation. And to make things worse, Spirit Breaker is not a common 
Diffusal Blade nor 
Disperser wielder to counter this problem at all.
* Overall, any attempt for Spirit Breaker to gank and kill Medusa will hurt him more than the other way around.
Spirit Breaker
* 
Nature's Grasp severely slows down Spirit Breaker, reducing effects of Charge of Darkness and Greater Bash.
* 
Living Armor can mitigate a large portion of Spirit Breaker's damage since his attacks are slow.
* Treant Protector can also counter-initiate against Spirit Breaker with 
Leech Seed, 
Overgrowth and with his root from Aghanim's Shard upgraded 
Nature's Guise before he manages to escape.
* Aghanim's Scepter gives Treant Protector access to 
Eyes In The Forest ability, which allows him to turn trees into wards that provide vision, allowing him to keep his allies warned about Spirit Breaker's attempts to gank them. Eyes In The Forest will also trigger Overgrowth if Spirit Breaker is in range of the tree affected by it.
Additional:
* Spirit Breaker's slow attacks cannot harm a hero shielded by Living Armor.
Spirit Breaker
* 
Pit of Malice can be cast in the path of Spirit Breaker's Charge of Darkness to cancel it.
* Spirit Breaker's damage output is entirely physical, therefore 
Atrophy Aura is very hazardous for him in most of the stages, particularly since it also affects 
Greater Bash, hindering Spirit Breaker's main source of damage.
* 
Fiend's Gate provides a way to escape from a gank for Underlord and his teammates. Likewise, Fiend's Gate can be used to ambush Spirit Breaker who has little to no ways of intercepting Underlord and his teammates when they use it to move around the map.

Spirit Breaker
* If Luna chooses to use 
Eclipse in anticipation right before Spirit Breaker gets to her with Charge of Darkness, she will be able to kill Spirit Breaker before he will be able to kill her as Spirit Breaker's attack speed is rather low.
* Meanwhile, when Spirit Breaker is focusing on any of Luna's allies with Charge of Darkness, Aghanim's Scepter upgraded Eclipse can be used to counter-initate against Spirit Breaker.
* Aghanim's Shard upgraded 
Moon Glaives allows Luna to reduce damage from Greater Bash and Nether Strike inflicts on her, and damage Spirit Breaker whenever he is close to her, even while he is invisible.
* 
Lucent Beam can be used to cancel Spirit Breaker's Charge of Darkness under the condition that Luna is able to cast it on time. Lucent Beam can also be used to cancel Nether Strike. But bear in mind, however, that Spirit Breaker can counter this with 
Planar Pocket from Aghanim's Shard which can be used to reflect Lucent Beam back at Luna.
* If Luna buys 
Linken's Sphere, it will become nearly impossible for Spirit Breaker to reach Luna unless some of Spirit Breaker's allies can pop it and put it on a cooldown.
* Even though Spirit Breaker can evade all of Luna's abilities with 
Shadow Blade, smart Luna will always buy 
Dust of Appearance to provide vision on Spirit Breaker to her and her team. Luna can also buy 
Gleipnir to counter Spirit Breaker's Charge of Darkness and Shadow Blade combo.
Additional:
* If Luna chooses to use Eclipse in anticipation right before Spirit Breaker gets to her with Charge of Darkness, she will be able to kill Spirit Breaker before he will be able to kill her as Spirit Breaker's attack speed is rather low.

Spirit Breaker
* Solar Guardian can save an ally getting targeted and focused by Spirit Breaker.
Spirit Breaker
* 
Malefice prevents Spirit Breaker from using his spells for the duration.
* Eidolons from 
Demonic Summoning have high magic resistance, receiving little damage from Charge of Darkness and Greater Bash.
* 
Midnight Pulse can deal big damage to Spirit Breaker, as it deals damage based on enemy hero's max health.
* 
Black Hole makes it very dangerous for Spirit Breaker to reach Enigma with Charge of Darkness unless if he has Nether Strike available to use.

* Black Hole makes it very dangerous for Spirit Breaker to reach Enigma with Charge of Darkness unless if he has Nether Strike available to use.
Spirit Breaker
* Due to Spirit Breaker's low attack speed, 
Tombstone is problematic for Spirit Breaker as the zombies summoned from Tombstone apply a stacking movement speed slow, which can significantly reduce Greater Bash's damage.
* 
Soul Rip and 
Decay allows Undying and his allies to survive and recover from any incoming ganks by Spirit Breaker.
Spirit Breaker
* 
Earthbind's root prevents/interrupts Charge of Darkness.
* As a single-target focused hero without much damage output, Spirit Breaker is ineffective in general against Meepo.
Skywrath Mage
* 
Skywrath Mage's abilities are single targeted and he can't use Mystic Flare to its fullest potential, since all Meepos spread the damage between them. He also has no disables to prevent Meepo from Poofing to another one (unless he can get Ancient Seal off first).
Spirit Breaker
* Heroes who can stun multiple units at once: 
Dark Willow, Spirit Breaker, 
Slardar, 
Invoker, and 
Tidehunter.
Spirit Breaker
* Ice Wall can slow down 
Charge of Darkness in its tracks at max level, allowing counterplays such as Cold Snap to end the charge, bursting down with Tornado, Meteor, and right clicks, or even teleporting back to spawn to drag Spirit Breaker into the fountain.
* Cold Snap (if timed right) and Invoker's other disables like Tornado can interrupt Charge of Darkness, especially since Charge is telegraphed by the symbol appearing over head.
Additional:
* 
Cold Snap allows Invoker to interrupt Charge of Darkness and Nether Strike.
* 
Tornado's long range can be used to cancel Charge of Darkness.
* 
Deafening Blast prevents Spirit Breaker from right clicking and thus proccing his Greater Bash.
Skywrath Mage
* Due to the high mana cost of his spells and the low cool down of them, Nether Ward can seriously damage Skywrath Mage if he isn't careful.
* Skywrath Mage's fragility makes him very susceptible to Pugna's high burst damage.
Additional:
* 
Nether Ward will make Skywrath Mage next to useless in fights, as his low hp pool will not allow him to sustain through the damage of the ward should he choose to cast spells. Be wary though that Skywrath's huge burst will make very quick work of Pugna's low hp should the ward be destroyed, and 
Decrepify won't help Pugna at all.
Spirit Breaker
* 
Nether Strike can't remove Static Link and reduces Spirit Breaker's physical damage output.
* Eye of the Storm melts Spirit Breaker's armor, and makes him much less tanky.
Additional:
* 
Plasma Field can slow Spirit Breaker and reduce damage from Greater Bash.
* 
Static Link drains damage bonus from Greater Bash, and it cannot be removed by Nether Strike.
* 
Storm Surge will proc on Spirit Breaker every time he attacks Razor or if he uses Charge of Darkness on Razor, damaging him and alerting Razor to Spirit Breaker's incoming ganks, no matter how far Spirit Breaker is from Razor.
* 
Eye of the Storm can rapidly reduce Spirit Breaker's armor, making him much less durable, especially in teamfights.
Spirit Breaker
* 
Searing Chains can stop Charge of Darkness if timed correctly.
* 
Activate Fire Remnant can be used to escape an approaching Spirit Breaker, or lead Spirit Breaker into a bad situation.
* 
Fire Remnant and 
Sleight of Fist allows Ember Spirit to dodge Charge of Darkness if timed correctly.
Spirit Breaker
* Spirit Breaker's slow attack speed and moderate damage do very little to harm Dragon Knight, even if ganked with Charge of Darkness.
Spirit Breaker
* Rubick can cancel Spirit Breaker's Charge of Darkness with 
Telekinesis under the condition that Rubick is able to cast it on time. And considering Rubick commonly buys 
Eul's Scepter of Divinity that can also cancel Charge of Darkness, Spirit Breaker will have a hard time charging Rubick or his allies until Spirit Breaker buys Shadow Blade. Telekinesis can also be used to cancel Nether Strike and Aghanim's Shard upgraded Telekinesis also allows Rubick to save his allies from Spirit Breaker.
* 
Fade Bolt weakens Spirit Breaker's damage output, reducing damage of Greater Bash.
* If Rubick succeeds to steal Charge of Darkness, he will be able to reduce much of Spirit Breaker's global presence. Rubick can also steal Nether Strike to further disable Spirit Breaker once he disables him with stolen Charge of Darkness. But bear in mind, however, that a skilled Spirit Breaker can use Bulldoze to prevent all that.
Skywrath Mage
* Skywrath Mage's very low health allows Monkey King to ambush and finish him off quickly.
Skywrath Mage
* In general, heroes that deal burst in multiple instances will trigger Borrowed Time and heal Abaddon for a large amount, such as Skywrath Mage, 
Techies, Juggernaut, Shadow Shaman, or 
Ogre Magi.
Additional:
* 
Aphotic Shield removes silences, slows and stuns, possibly foiling a full-duration Mystic Flare.
* 
Borrowed Time makes it impossible to burst 
Abaddon down, even healing him up due to Mystic Flare's damage.
Spirit Breaker
* Heroes with summons and illusions as Spirit Breaker has no strong AoE capabilities to deal with them: Chaos Knight, Phantom Lancer, Terrorblade, Naga Siren, Broodmother, Warlock, Visage, Nature's Prophet, Shadow Shaman, Lycan, Wraith King.
Spirit Breaker
* Heroes that punish mobile heroes: 
Bloodseeker, 
Keeper of the Light, 
Kunkka, 
Disruptor.
Spirit Breaker
* Heroes that can slow Charge of Darkness by a huge amount: 
Venomancer, 
Viper, 
Dazzle, 
Arc Warden, Lion, 
Huskar, Shadow Shaman, Visage, 
Undying, 
Jakiro.
Spirit Breaker
* Heroes with gap-closing abilities who attempt to use them for escaping Bloodseeker will suffer serious damage from Rupture: Phantom Assassin, 
Anti-Mage, 
Faceless Void, Riki, 
Slark, Spirit Breaker.
Skywrath Mage
* Skywrath's pitiful defences also make him easy meat to heroes with high burst like Juggernaut, Lion, or Phantom Assassin, the latter occasionally downing a support Skywrath in a single Stifling Dagger.
Skywrath Mage
* 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.
Spirit Breaker
* Heroes that can cancel Charge of Darkness: Ogre Magi, 
Earthshaker, Lion, 
Rubick, 
Lina, 
Luna, Jakiro, 
Dawnbreaker, 
Alchemist, Ogre Magi, 
Axe, Shadow Shaman, Naga Siren, 
Mars, 
Bane, Pudge, Clockwerk.
Spirit Breaker
* Heroes with ways to protect themselves or allies from Spirit Breaker's initiation: 
Shadow Demon, 
Outworld Destroyer, Omniknight, Dawnbreaker.
Spirit Breaker
* Heroes that can cancel Charge of Darkness: Ogre Magi, Earthshaker, Lion, Rubick, Lina, Luna, Jakiro, Dawnbreaker, Alchemist, Ogre Magi, Axe, Shadow Shaman, Naga Siren, Mars, Bane, Pudge, Clockwerk.
Spirit Breaker
* Heroes who can continue dealing damage even while being stunned: Luna, 
Razor, Axe, 
Bristleback, 
Leshrac, 
Death Prophet, Jakiro.
Skywrath Mage
* Heroes with silence such as Riki, Silencer, or Night Stalker prevents Skywrath Mage from using his spells.
Spirit Breaker
* Heroes that can slow Charge of Darkness by a huge amount: Venomancer, Viper, Dazzle, Arc Warden, Lion, Huskar, Shadow Shaman, Visage, Undying, Jakiro.

* Heroes that can cancel Charge of Darkness: Ogre Magi, Earthshaker, Lion, Rubick, Lina, Luna, Jakiro, Dawnbreaker, Alchemist, Ogre Magi, Axe, Shadow Shaman, Naga Siren, Mars, Bane, Pudge, Clockwerk.
Spirit Breaker
* Durable heroes: Axe, Dawnbreaker, Bristleback, Mars, Omniknight, Tidehunter, Wraith King, 
Primal Beast, 
Underlord.
Spirit Breaker
* Heroes with mobility spells like 
Queen of Pain, Anti-Mage, Phantom Assassin, Riki, 
Puck, and Spirit Breaker that are cancelled by Frostbite can suffer greatly from the presence of Crystal Maiden. It is absolutely critical, however, to have followup from teammates, as all of the above heroes can make quick work of the squishy Crystal Maiden after they are released from her grip.
Spirit Breaker
* Heroes who can continue dealing damage even while being stunned: Luna, Razor, Axe, Bristleback, Leshrac, Death Prophet, Jakiro.
Spirit Breaker
* Heroes who rely on burst damage with magical damage will struggle to kill Primal Beast: Spirit Breaker, 
Gyrocopter, Leshrac
Spirit Breaker
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, 
Earth Spirit, Faceless Void, 
Magnus, 
Mirana, 
Monkey King, 
Morphling, 
Pangolier, Phantom Assassin, 
Phoenix, Puck, Queen of Pain, Riki, 
Sand King, Spirit Breaker, 
Timbersaw, 
Tusk.
Spirit Breaker
* Heroes that can slow Charge of Darkness by a huge amount: Venomancer, Viper, Dazzle, Arc Warden, Lion, Huskar, Shadow Shaman, Visage, Undying, Jakiro.
Spirit Breaker
* Heroes who rely on armor or evasion to survive can easily be bursted down, like Phantom Assassin, Terrorblade, Underlord, Spirit Breaker.
Skywrath Mage
* Skywrath Mage also has a terrible time fighting against anything that isn't a hero. His skills are mostly target-based and he has terrible strength and agility, he can easily be kited or harassed by illusion-based heroes like Chaos Knight and Phantom Lancer, or by Heroes that summon other units like Lone Druid, Lycan and Beastmaster.
Spirit Breaker
* Heroes with summons and illusions as Spirit Breaker has no strong AoE capabilities to deal with them: Chaos Knight, Phantom Lancer, Terrorblade, Naga Siren, Broodmother, Warlock, Visage, Nature's Prophet, Shadow Shaman, Lycan, Wraith King.

Spirit Breaker
* Charge of Darkness provides shared vision over its target, keeping track of heroes who rely on invisibility, mobility, or illusions: Riki, Broodmother, Phantom Lancer
Spirit Breaker
* Clockwerk can use Power Cogs to repel Spirit Breaker when he charges in with Charge of Darkness.
* Spirit Breaker's slow 0.6 second attack animation attacks do little damage against Clockwerk. It can also constantly be interrupted by Battery Assault.
* Nether Strike's 1.2 second charge time gives Clockwerk plenty of time to activate 
Blade Mail and for Battery Assault to cancel it.
Additional:
* 
Battery Assault will continuously prevent Spirit Breaker from using Nether Strike, Charge of Darkness and even right clicking because of his slow base attack speed.
Skywrath Mage
* Skywrath Mage's 
Mystic Flare can deal huge damage to Clockwerk inside his Power Cogs.
Spirit Breaker
* Can easily interrupt and disable Spirit Breaker with hex if being charged.
Spirit Breaker
* Heroes that are squishy by nature are an easy target for Spirit Breaker: 
Sniper, 
Drow Ranger, Shadow Shaman
Spirit Breaker
* Heroes that can slow Charge of Darkness by a huge amount: Venomancer, Viper, Dazzle, Arc Warden, Lion, Huskar, Shadow Shaman, Visage, Undying, Jakiro.
Skywrath Mage
* Skywrath Mage's armor and agility gain is very low, so when Huskar's 
Burning Spears stack they can take him down very quickly at any point of the game.
* 
Berserker's Blood grants bonuses as Huskar uses Burning Spears to harass Skywrath Mage, granting him attack speed, magic resistance, and strength as health regen, making it possible that Huskar can harass Skywrath Mage out of lane and sustain through his magic burst through staying injured throughout lane, or even the game.
* 
Life Break allows Huskar to jump onto Skywrath Mage, closing the distance between them and busting him down so he cannot run. This can be combed with 
Inner Fire, adding a movement speed slow if Aghanim's Shard is applied so Skywrath Mage cannot escape.
Spirit Breaker
* Spirit Breaker's stuns pierce spell immunity, making him a good choice against heroes that heavily rely on 
Black King Bar; Huskar
Skywrath Mage
* Heroes with high magical burst can easily kill Huskar when he is at low health: Lion, Lina, Skywrath Mage
Spirit Breaker
* Due to Spirit Breaker's low attack speed, 
Supernova is problematic for Spirit Breaker to take down, and even more so with 
Fire Spirits debuff applied.
Skywrath Mage
* Silence (and mana burns) will be a persistent problem for Phoenix, as it is heavily reliant on its abilities whether defensively or offensively, so heroes like Death Prophet, Skywrath Mage, and even Nyx Assassin must be closely observed to prevent being shut down by these heroes.
* Hexes are a greater threat to Phoenix as they also disable items, preventing Phoenix from dispelling the debuff on its own.
Skywrath Mage
* Due to his low health and armor, Riki can easily kill Skywrath Mage.
* Smoke Screen prevents Skywrath from using all of his abilities, as he does not tend to buy Black King Bar.
* However, Skywrath Mage can easily kill Riki if he manages to root Riki with Rod of Atos or Gleipnir, followed by Dust of Appearance, Ancient Seal and Mystic Flare.
Spirit Breaker
* Charge of Darkness provides shared vision over its target, keeping track of heroes who rely on invisibility, mobility, or illusions: Riki, Broodmother, Phantom Lancer
Skywrath Mage
* Templar Assassin easily withstands all the damage from Skyrwrath Mage, thanks to its first ability 
Refraction. In addition, Templar Assassin can kill Skywrath Mage with a single hit from under the second ability 
Meld.
Additional:
* Templar Assassin easily withstands all the damage from Skyrwrath Mage, thanks to its first ability Refraction. In addition, Templar Assassin can kill Skywrath Mage with a single hit from under the second ability Meld.
Spirit Breaker
* 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.
Spirit Breaker
* Heroes with summons and illusions as Spirit Breaker has no strong AoE capabilities to deal with them: Chaos Knight, Phantom Lancer, Terrorblade, Naga Siren, Broodmother, Warlock, Visage, Nature's Prophet, Shadow Shaman, Lycan, Wraith King.
Skywrath Mage
* Once you get a Black King Bar, squishy spellcasters like 
Zeus, Skywrath Mage and others will be probably easy to deal with.
Spirit Breaker
* Charge of Darkness allows Spirit Breaker to catch up to Lycan after he uses Shapeshift.
Additional:
* Vision from Charge of Darkness will easier to catch Lycan 
Shapeshift and Charge of Darkness out of reach Lycan 
Summon Wolves and Lycan's other creeps. Until upgrade Aghanim's Scepter faster catching Lycan Shapeshift.
Spirit Breaker
* Magic Missile has a considerably long cast time, making it difficult to stop Charge of Darkness with it.
* Other than Magic Missile, Vengeful Spirit has no way of canceling Nether Strike.
Skywrath Mage
* Skywrath Mage should have the upper hand against Vengeful Spirit with Ancient Seal.
* Vengeful is highly dependant on her abilities and has no natural means to deal against silences.
* Her low attack range allows Skywrath Mage to easily bully her out of the lane.
Spirit Breaker
* Tinker relies on his high mobility from 
Boots of Travel and 
Blink Dagger to survive. Those items don't help him if Spirit Breaker manages to cast Charge of Darkness on him.
* Spirit Breaker can easily cancel 
Rearm and Boots of Travel.
Skywrath Mage
* Skywrath Mage stands perfectly on the center line against Tinker, thanks to his nuke and silence. Also, thanks to his abilities, he can quickly kill a victim, and Tinker is one of the most subtle heroes in the game
Additional:
* Skywrath Mage stands perfectly on the center line against Tinker, thanks to his nuke and silence. Also, thanks to his abilities, he can quickly kill a victim, and Tinker is one of the most subtle heroes in the game
Spirit Breaker
* Possibly Clinkz's worst enemy. He has many tools to utterly destroy Clinkz.
* Charge of Darkness can be used on Clinkz if Spirit Breaker's team spots him anywhere. This charge will track his location through Skeleton Walk's invisibility and movement speed bonuses.
* When Spirit Breaker charges onto Clinkz, he can easily use Dust of Appearance to guarantee a reveal on him while stunned.
* All three of Spirit Breaker's spells help him and his team quickly close the gap to Clinkz even at the edge of his attack range or when running away with Skeleton Walk.
* Spirit Breaker's high strength and above average armor makes him able to endure Clinkz's onslaught, meanwhile Clinkz will be heavily threatened if Spirit Breaker procs a Greater Bash.
Additional:
* Once caught with dust, Clinkz could be locked down for a long time by Spirit Breaker and has nowhere to escape.
* Charge of Darkness provides shared vision over its target, showing Clinkz even when he is in 
Skeleton Walk.
Skywrath Mage
* Even though Linken's Sphere will block your silence, you can cast Arcane Bolt to break it or wait until someone on your team breaks it. In addition, Linken's Sphere builders are usually squishy targets vulnerable to silences: 
Weaver, Queen of Pain, Morphling, 
Clinkz, etc. Don't forget that Ancient Seal also increases the magical damage these enemies take, along with silencing them.
Spirit Breaker
* Charge of Darkness can be used to escape or counter-initiate against a Relocate gank.
* Greater Bash and Nether Strike is devastating due to Io's low armor, and can even knock it away from his 
Tethered target.
Skywrath Mage
* 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.
Spirit Breaker
* Heroes that can easily bypass Chen's creeps to get to Chen: Riki, Tusk, Clinkz, Sniper, Slark, Phantom Assassin, Void Spirit, 
Storm Spirit, Ember Spirit, Earth Spirit, Spirit Breaker.
Skywrath Mage
* 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.
Spirit Breaker
* Heroes with long range abilities are also able to touch Zeus, such as Clockwerk, Kunkka, Puck, Skywrath Mage, Spirit Breaker, Tusk and others.
Skywrath Mage
* Heroes with long range abilities are also able to touch Zeus, such as Clockwerk, Kunkka, Puck, Skywrath Mage, Spirit Breaker, Tusk and others.
Spirit Breaker
* Windranger tends to fare badly against high mobility heroes that can easily dodge Powershot, close the gap on her when she uses Windrun or escape from Focus Fire's reach. Examples of such heroes include Spirit Breaker, Lycan, Storm Spirit, Earth Spirit, Void Spirit, Slark and others.
Skywrath Mage
* 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.
Spirit Breaker
* 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.
Skywrath Mage
* 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.
Spirit Breaker
* Heroes with summons and illusions as Spirit Breaker has no strong AoE capabilities to deal with them: Chaos Knight, Phantom Lancer, Terrorblade, Naga Siren, Broodmother, Warlock, Visage, Nature's Prophet, Shadow Shaman, Lycan, Wraith King.
Spirit Breaker
* Unlike with other heroes who can summon illusions of themselves, Terrorblade's illusions from 
Conjure Image have different colors than other illusions which can be seen even by enemy team, which can also make Terrorblade weak even against heroes he naturally counters: Bane, 
Lifestealer, Spectre, Chaos Knight, Spirit Breaker, Sniper. Terrorblade's only solution to counter this problem is to get 
Manta Style as quickly as possible.
Skywrath Mage
* 
Arcane Bolt can target Terrorblade's low health pool in the laning phase.
* Ancient Seal can prevent Terrorblade from casting Sunder.
* Mystic Flare can be used to great effect to burst Terrorblade down before he gets a Manta Style or a Black King Bar.
Spirit Breaker
* Charge of Darkness can be used to chase down Pangolier if he escapes with Swashbuckle or Rolling Thunder.
* Nether Strike ignores Rolling Thunder's spell immunity, and will still hit Pangolier if he rolls or dashes away.
Spirit Breaker
* Spirit Breaker can charge towards Sniper from anywhere on the map with Charge of Darkness.
* Greater Bash deals magical damage, which can prove dangerous to Sniper and his low health.
* Both previous abilities combined with Nether Strike ensures that Spirit Breaker can easily solo kill Sniper.
Spirit Breaker
* Heroes that usually build Linken's Sphere as either a core or situational item: Weaver, 
Medusa, Morphling, Queen of Pain, Storm Spirit, Luna, Naga Siren.
Spirit Breaker
* 
Shukuchi vision can easily target Charge of Darkness before Weaver purchase Linken's Sphere.
Additional:
* Spirit Breaker's strong escape combo abilities from Charge of Darkness and 
Bulldoze can easily catch Shukuchi from Weaver.
* Time Lapse cannot dispel neither Charge of Darkness nor Nether Strike.
* However, Weaver is a common Linken's Sphere wielder. And if he has it, Spirit Breaker will not be able to catch up with Weaver neiter with Charge of Darkness nor with Nether Strike.
Skywrath Mage
* Even though Linken's Sphere will block your silence, you can cast Arcane Bolt to break it or wait until someone on your team breaks it. In addition, Linken's Sphere builders are usually squishy targets vulnerable to silences: Weaver, Queen of Pain, Morphling, Clinkz, etc. Don't forget that Ancient Seal also increases the magical damage these enemies take, along with silencing them.
Additional:
* Arcane Bolt has a long range and a low cooldown, and is a great spell to waste Linken's Sphere. It also serves as an effective spell to harass Weaver with.
* Ancient Seal prevents Weaver from using Shukuchi or Time Lapse.
Skywrath Mage
* Magical burst damage is Timbersaw's weakness, and Ancient Seal not only amplifies it but also prevents him from using 
Timber Chain to escape for up to 6 seconds.
* He generally doesn't build early items to deal with silences.
* 
Reactive Armor does not trigger on magic damage or spells, meaning that even a 
Pipe of Insight won't give him the massive sustain he normally gets from attacks.
Additional:
* Skywrath Mage's long range and low cooldown magic damage spells can easily harass Timbersaw out of lane.
* Ancient Seal is not only a long lasting silence, (one of Timbersaw's biggest weaknesses) but it also makes him even more vulnerable to magical burst damage.
Skywrath Mage
* Skywrath's pitiful defences also make him easy meat to heroes with high burst like Juggernaut, Lion, or Phantom Assassin, the latter occasionally downing a support Skywrath in a single Stifling Dagger.
Spirit Breaker
* Heroes that rely on escapes to stay alive can be caught and locked down for a long time: Queen of Pain, Phantom Assassin
Skywrath Mage
* While Phantom Assassin can kill Skywrath Mage in a few strikes, Skywrath Mage can also do the same to her if she is not careful.
* Arcane Bolt's long range and low cooldowns allows Skywrath Mage to severely harass Phantom Assassin in lane.
* Ancient Seal prevents Phantom Assassin from escaping or engaging with 
Phantom Strike.
* Mystic Flare's heavy magical damage nukes Phantom Assassin down quickly during the early to mid game.
Additional:
* While Phantom Assassin can kill Skywrath Mage in a few strikes, Skywrath Mage can also do the same to her if she is not careful.
* Arcane Bolt's long range and low cooldowns allows Skywrath Mage to severely harass Phantom Assassin in lane.
* Ancient Seal prevents Phantom Assassin from escaping or engaging with Phantom Strike.
* Mystic Flare's heavy magical damage nukes Phantom Assassin down quickly during the early to mid game.
Spirit Breaker
* Heroes that usually build Linken's Sphere as either a core or situational item: Weaver, Medusa, Morphling, Queen of Pain, Storm Spirit, Luna, Naga Siren.
Spirit Breaker
* Heroes that rely on escapes to stay alive can be caught and locked down for a long time: Queen of Pain, Phantom Assassin
Skywrath Mage
* A good Skywrath Mage with quick fingers will punish Queen of Pain for blinking aggressively. Ancient Seal is a six second silence with no cast time, so he can interrupt either her Shadow Strike or Sonic Wave, and a good Mystic Flare on top of that will seal the deal for her.
* Ancient Seal also has pretty good range so he could get it off before she blinks away.
Skywrath Mage
* Ancient Seal's instant cast time will often silence Brewmaster before he can do anything.
* Brewmaster also has no defense against Skywrath Mage's massive magical damage.
Skywrath Mage
* Mystic Flare can easily burst down Legion Commander while she is Dueling.
Skywrath Mage
* 
Cold Embrace is a perfect setup for Mystic Flare.
* Winter Wyvern is a spellcaster, and the 6 second silence from Ancient Seal can prevent her from contributing much.
* Because Skywrath Mage tends to stay back in fights, Winter Wyvern will have to get close to a teamfight to cast 
Winter's Curse on him. And if she chooses to cast it on one of his allies, his low attack speed and damage means that he won't do much.
* However, bear in mind that Skywrath Mage has seriously awful armor, and that can make him an adequate target to being turned against his own team with Winter's Curse, which can result in his death quickly.
Additional:
* Cold Embrace is the perfect setup for Mystic Flare, and his 6-second silence is good against Winter Wyvern in general.
Spirit Breaker
* Heroes that rely on invisibility can be tracked with Charge of Darkness opening them to team attacks: Bounty Hunter, Mirana, Riki
Skywrath Mage
* Heroes that can easily kill Faceless Void from outside his Cronosphere; Sniper, Skywrath Mage, etc.
Skywrath Mage
* Heroes with powerful spammable abilities will prove problematic for Grimstroke as Ink Swell does not protect him from them: Zeus, Skywrath Mage, Tinker, Lina
Skywrath Mage
* 
Mana Break drains Skywrath Mage of his mana, slowing him and dealing bonus damage while rendering him unable to cast his spells.
* 
Blink makes it incredibly easy for Anti-Mage to close the gap between himself Skywrath Mage to right-click him down. He can also use Blink to get away and escape into fog of war.
* Anti-Mage passively reduces enemy spell damage with 
Counterspell, and can activate the ability to block and send back Skywrath's Ancient Seal or Arcane Bolt, causing him to silence himself or deal massive damage to himself.
* Skywrath Mage's large mana-costs makes him an easy target for 
Mana Void.
* Anti-Mage often builds Black King Bar and Manta Style which can dispel Ancient Seal and Concussive Shot.
Spirit Breaker
* Anti-Mage usually relies on Blink to escape, but with vision from Charge of Darkness it is easier to catch him.
* Spirit Breaker could single-handedly lock Anti-Mage down for 4 seconds (or even more with lucky bashes), allowing his teammates to follow up.
* As Anti-Mage is an elusive hero who likes to farm alone, Spirit Breaker could choose to charge whenever Anti-Mage is in sight.
Skywrath Mage
* Heroes with abilities or items that can silence or disable Anti-Mage for long periods of time will prevent him from Blinking away: Lion, Silencer, Shadow Shaman, 
Grimstroke, 
Witch Doctor, Riki, Faceless Void, Skywrath Mage, Puck.
Spirit Breaker
* Axe, Bristleback, 
Centaur Warrunner, Spirit Breaker, Pudge, Huskar, Wraith King, 
Doom: These heroes are too tanky for Puck to burst down. Also, all of them have spells which can deal with and shut Puck down reliably.
Spirit Breaker
* Generally, heroes that can close the gap on Drow Ranger to cancel her Marksmanship such as Phantom Assassin, Spirit Breaker, and Tusk are effective at limiting her power and bursting her down.
Skywrath Mage
* Lich is heavily reliant on his abilities to contribute to team fights, so be wary of enemies that can Silence: Bloodseeker, Death Prophet, Silencer, Drow Ranger, Skywrath Mage.
Spirit Breaker
* Heroes with summons and illusions as Spirit Breaker has no strong AoE capabilities to deal with them: Chaos Knight, Phantom Lancer, Terrorblade, Naga Siren, Broodmother, Warlock, Visage, Nature's Prophet, Shadow Shaman, Lycan, Wraith King.
Spirit Breaker
* Spirit Breaker can chase Nature's Prophet from anywhere on the map with Charge of Darkness, making it hard for Nature's Prophet to split-push.
* Charge of Darkness and Nether Strike gives vision of Nature's Prophet when he tries to Sprout himself and teleport away.
Additional:
* Charge of Darkness allows Spirit Breaker to catch Nature's Prophet out when he tries to split push.
* Nature's Prophet can't hide in his 
Sprout against Spirit Breaker, as his Charge of Darkness provides vision on its target.
* Spirit Breaker can easily cancel Nature's Prophet's 
Teleportation.
Spirit Breaker
* Heroes that can slow Charge of Darkness by a huge amount: Venomancer, Viper, Dazzle, Arc Warden, Lion, Huskar, Shadow Shaman, Visage, Undying, Jakiro.
Skywrath Mage
* Ancient Seal can silence Jakiro and make him vulnerable to magical spells up to 6 seconds.
* Skywrath Mage can usually burst down Jakiro with his high damage magical spells.
Spirit Breaker
* Heroes that usually build Linken's Sphere as either a core or situational item: Weaver, Medusa, Morphling, Queen of Pain, Storm Spirit, Luna, Naga Siren.
Skywrath Mage
* Similar to Timbersaw, Storm Spirit builds items that don't help against silences.
* An 
Orchid Malevolence will most likely silence you first. However, if you grab a Eul's Scepter of Divinity, you might dispel his silence and turn the tides to your favor.
* Root and silence are Storm Spirit's ultimate counters. Skywrath Mage has a silence in his kit, and has 
Rod of Atos as his core item. If he dispels one, you cast the other, both leaving him vulnerable.
* If he builds Black King Bar, he spends 4050 gold that doesn't help him snowball effectively.
Skywrath Mage
* Skywrath Mage also has a terrible time fighting against anything that isn't a hero. His skills are mostly target-based and he has terrible strength and agility, he can easily be kited or harassed by illusion-based heroes like Chaos Knight and Phantom Lancer, or by Heroes that summon other units like Lone Druid, Lycan and Beastmaster.
Skywrath Mage
* Mystic Flare can be used to effectively ignore the Spirit Bear entirely and burst Lone Druid during the early mid game.
* 
Concussive Shot and Arcane Bolt will provide vision of Lone Druid allowing for better chase in teamfights before the Spirit Bear can do too much damage.
* Ancient Seal denies the ability to transform into 
True Form and receive bonus HP from the skill.
Skywrath Mage
* Heroes with a low health pool (
Crystal Maiden, Skywrath Mage etc)
Spirit Breaker
* Charge of Darkness allows Spirit Breaker to gank Shadow Fiend in the early game, preventing him from getting Necromastery stacks.
* Nether Strike and Charge of Darkness can be used to prevent Shadow Fiend from casting Requiem of Souls.
Spirit Breaker
* Heroes that can cancel Charge of Darkness: Ogre Magi, Earthshaker, Lion, Rubick, Lina, Luna, Jakiro, Dawnbreaker, Alchemist, Ogre Magi, Axe, Shadow Shaman, Naga Siren, Mars, Bane, Pudge, Clockwerk.
Skywrath Mage
* Skywrath Mage can easily harass Alchemist in the laning phase with multiple Arcane Bolts. Additionally, if Alchemist is in the process of throwing an 
Unstable Concoction, and has no way to dispel Ancient Seal, the self stun becomes an easy set up for Mystic Flare.
* Caution, however, as a decently farmed Alchemist with {Item ID:Radiance} and {Item ID:Manta Style} can easily send illusions to harass and force Skywrath Mage out.
Skywrath Mage
* 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.
Spirit Breaker
* 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.
Spirit Breaker
* Spirit Breaker won’t do much harm to Enchantress because of Untouchable and Nature's Attendants. Unless Enchantress is low on HP, Spirit Breaker won’t be able to catch her with mere spells.
Spirit Breaker
* Heroes with nukes that can jump her: Clockwerk, 
Snapfire, Spirit Breaker, Techies
Skywrath Mage
* Heroes with nukes: Bane, 
Lich, Lion, Skywrath Mage
Additional:
* 
Untouchable is useless versus constant Arcane Bolts, and it doesn't help that her strength gain is the lowest in the game.
* A jungle Enchantress can weaken lanes and make Skywrath Mage's job easier.
* The magic amplification from Ancient Seal makes her even squishier to Skywrath and his allies' magic nukes.
Spirit Breaker
* 
Morph allows Morphling to copy abilities of Spirit Breaker and combine them with 
Waveform to turn things around. Aghanim's Scepter upgraded Morph also allows Morphling to create a strong illusion of Spirit Breaker that can cast all of his basic abilities. This allows Morphling to give Spirit Breaker a taste of his own medicine.
* Spirit Breaker's low attack speed and lack of burst damage makes it unlikely for him to win against Morphling when he has 
Attribute Shift (Strength Gain) toggled on.
Skywrath Mage
* Arcane Bolt's low cooldown allows him to deal consistent damage to Morphling, and is a viable way to disable Linken's Sphere.
* Ancient Seal prevents Morphling from using any of his skills, giving Skywrath Mage and his team ample time to burst Morphling down.
* Mystic Flare coupled with a stun/root can easily burst Morphling down, especially if he has more stats shifted to Agility.
* Alternatively, Morphling can use Morph to use Skywrath Mage's own silence and nukes against him.
Spirit Breaker
* Durable heroes: Axe, Dawnbreaker, Bristleback, Mars, Omniknight, Tidehunter, Wraith King, Primal Beast, Underlord.
Skywrath Mage
* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, Dark Willow, 
Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, 
Oracle.
Spirit Breaker
* Heroes who can continue dealing damage even while being stunned: Luna, Razor, Axe, Bristleback, Leshrac, Death Prophet, Jakiro.
Spirit Breaker
* Spirit Breaker's Nether Strike with Aghanim's Shard disables Bristleback's passives.
Spirit Breaker
* Heroes with summons and illusions as Spirit Breaker has no strong AoE capabilities to deal with them: Chaos Knight, Phantom Lancer, Terrorblade, Naga Siren, Broodmother, Warlock, Visage, Nature's Prophet, Shadow Shaman, Lycan, Wraith King.
Spirit Breaker
* Heroes with long-lasting, undispellable debuffs will pinpoint the true Naga Siren: Spirit Breaker, Bloodseeker, Witch Doctor.
Spirit Breaker
* Fissure interrupts Spirit Breaker during Charge of Darkness.
Skywrath Mage
* Arcane Bolt allows Skywrath Mage to harass Earthshaker out of lane.
* Ancient Seal is an instant silence that can be pre-cast onto Earthshaker to disrupt his combo, before he uses Blink Dagger to initiate.
* Mystic Flare will nuke Earthshaker down while he stands in place during his long cast animations.
Spirit Breaker
* Bramble Maze stops Charge of Darkness in its tracks. Its very long duration means it can be used as an obstacle to block off an incoming Spirit Break during teamfights.
* Shadow Realm and Bedlam can be activated when Dark Willow sees Charge of Darkness coming, preventing Spirit Breaker from using Nether Strike after the initial stun.
Skywrath Mage
* Ancient Seal instantly shuts down Dark Willow's abilities, rendering her defenseless against his high burst damage spells, while she cannot cast spells of her own.
* Mystic Flare deals immense burst damage in an area, damaging Dark Willow through Shadow Realm.
Spirit Breaker
* Heroes with summons and illusions as Spirit Breaker has no strong AoE capabilities to deal with them: Chaos Knight, Phantom Lancer, Terrorblade, Naga Siren, Broodmother, Warlock, Visage, Nature's Prophet, Shadow Shaman, Lycan, Wraith King.
Spirit Breaker
* Warlock is a very strong hero when positioned correctly, and his long cast range helps him with this. However, some heroes might disrupt or sneakily pass through his allies and deal with him, preventing him from doing his job. Such heroes include Chaos Knight, Spirit Breaker, Riki, and more.
Spirit Breaker
* With Aghanim's Scepter, Broodmother will gain access to 
Spinner's Snare, which will allow her to create invisible lines on her webs from 
Spin Web that will root, deal damage over time, and reveal enemy heroes if they unwittingly step on them. This allows Broodmother to keep her allies alerted on heroes who rely on invisibility-themed and movement-themed abilities and items to surprise enemy heroes and disrupt ganking attempts of enemy heroes: Phantom Assassin, Nyx Assassin, Mirana, Bounty Hunter, 
Templar Assassin, Riki, Spirit Breaker, Anti-Mage, Tusk, Ursa, Nature's Prophet, Enigma, Void Spirit, Magnus etc.
Spirit Breaker
* Charge of Darkness provides shared vision over its target, keeping track of heroes who rely on invisibility, mobility, or illusions: Riki, Broodmother, Phantom Lancer
Spirit Breaker
*
Astral Imprisonment can be used to protect allies by imprisoning either them or Spirit Breaker.
Arcane Orb will heavily drain Spirit Breaker's maximum mana, rendering him almost useless and unable to cast spells. And considering how Spirit Breaker's intelligence is very low, 
Sanity's Eclipse will deal a lot of damage to him.
Sanity's Eclipse, mana allergy applied by the 
Sanity's Eclipse will discourage Spirit Breaker from using his abilities as it will cause him to lose health and heal Outworld Destroyer.
*
* Even if Spirit Breaker survives
Skywrath Mage
* Outworld Destroyer can steal more mana with
Astral Imprisonment from 
Skywrath Mage with 
Shield of the Scion (granted by 
Aghanim's Shard). Shield of the Scion grants Skywrath Mage bonus intelligence every time he deals magic damage to an enemy hero with his abilities. The higher his intelligence, the larger his mana pool. Since Astral Imprisonment steals based on the target's max mana, Outworld Destroyer can steal much more mana from Skywrath Mage.
