Mirana
* 
Sacred Arrow can be instantly dispelled by Aphotic Shield.
Additional:
* Abaddon can remove Sacred Arrow's stun from his teammates with 
Aphotic Shield, or remove it from himself with 
Borrowed Time.
* Borrowed Time makes Abaddon almost impossible to burst down with Mirana's 
Aghanim's Scepter combo.
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.
Mirana
* Heroes that have superior mobility that can easily catch up with Mirana even after she used Leap to escape: 
Anti-Mage, 
Queen of Pain, 
Storm Spirit, 
Riki.
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.
Mirana
* Mirana's Leap is ineffective if Lycan uses 
Shapeshift. It also allows him to dodge Sacred Arrow.
Skywrath Mage
* Once you get a Black King Bar, squishy spellcasters like 
Zeus, Skywrath Mage and others will be probably easy to deal with.
Mirana
* Heroes that can protect or dispel stunned allies such as 
Legion Commander, 
Outworld Destroyer, 
Shadow Demon and 
Oracle can reduce the effectiveness of Sacred Arrow.
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.
Mirana
* The long silence of 
Crippling Fear at night prevents Mirana from escaping with Moonlight Shadow and Leap. She also has really low base health, so Night Stalker can usually kill her during one cast of Crippling Fear at night.
* With 
Dark Ascension and 
Gem of True Sight, Night Stalker can find and kill Mirana, and he is a tanky hero capable of fighting Mirana any stage of the game.
Skywrath Mage
* Heroes with silence such as Riki, 
Silencer, or 
Night Stalker prevents Skywrath Mage from using his spells.
Mirana
* 
Track detects Mirana and her allies during Moonlight Shadow.
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.
Mirana
* 
Mirana cannot use Leap while rooted by Earthbind and her Moonlight Shadow is countered by Meepo's true sight that is provided by Earthbind.
Additional:
* 
Earthbind prevents Mirana from Leaping or going invisible with Moonlight Shadow. She can be easily killed by 
Poof and 
Ransack while disabled.
* Landing a Sacred Arrow on Meepo does not render him helpless, as all of the other Meepos can still fight back.
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).
Mirana
* Heroes with summons or illusions makes Sacred Arrow harder to land: Shadow Demon, 
Phantom Lancer, 
Nature's Prophet.
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.
Mirana
* Heroes with silences and hard stuns such as 
Doom, Silencer, and 
Lion can keep Mirana from Leaping away.
Skywrath Mage
* Heroes with silence such as Riki, Silencer, or Night Stalker prevents Skywrath Mage from using his spells.
Mirana
* Arc Warden can use his summons to prevent Sacred Arrow from hitting himself or his allies.
* Mirana doesn't build items that give armor often, so she usually can't fight against a late game Arc Warden.
Additional:
* 
Flux will slow and damage Mirana even after she Leaps, since she will likely not be near allies.
* Arc Warden can place 
Magnetic Field on an ally who has been hit by Sacred Arrow to protect them.
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.
Mirana
* Though Mirana can clear waves of Broodmother's spiderlings with 
Starstorm, Broodmother will often stick with her spiderlings from 
Spawn Spiderlings, which in combination with the huge speed provided by 
Spin Web can make it hard for Mirana to hit her with Sacred Arrow.
* Broodmother commonly buys 
Orchid Malevolence and it's upgrade 
Bloodthorn, which allows her to prevent Mirana from escaping with both, 
Leap and 
Moonlight Shadow and from fighting back with Starstorm.

* Broodmother commonly buys Orchid Malevolence and it's upgrade Bloodthorn, which allows her to prevent Mirana from escaping with both, Leap and Moonlight Shadow and from fighting back with Starstorm.
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.
Mirana
* Moonlight Shadow does little good against Dragon Slave and Light Strike Array.
* Lina's damage burst can quickly kill Mirana's teammates before she saves them with Moonlight Shadow.
Additional:
* 
Eul's Scepter of Divinity is an item Lina commonly buys, which in combination with and 
Light Strike Array can disable Mirana if she tries to Leap away.
* 
Laguna Blade's magical (pure with Laguna Blade damage is Pure and pierces Spell Immunity talent) burst damage takes advantage of Mirana's below average health.
Mirana
* Thirst detects Mirana or her ally at low health during Moonlight Shadow.
* Rupture deals high damage when Mirana uses Leap.
Additional:
* 
Rupture can quickly kill Mirana if she tries to Leap away.
* 
Thirst detects Mirana and her allies during Moonlight Shadow.
Mirana
* If Slark sees the Sacred Arrow before it hits him, he can use 
Dark Pact to remove it a moment later.
* 
Pounce prevents Mirana from escaping with Leap.
* Slark can survive Mirana's Aghanim's Scepter combo with 
Shadow Dance.
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.
Skywrath Mage
* Skywrath Mage's very low health allows Monkey King to ambush and finish him off quickly.
Mirana
* 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.
Mirana
* All abilities from Mirana can shut down with 
Doom and Mirana can not escape with Leap since Doom activated.
* Doom also catch Mirana disabled used combo items Doom from ugrade Aghanim's Scepter and 
Blink Dagger or 
Overwhelming Blink make Mirana can not move escaping notably Leap and Moonlight Shadow.
Mirana
* Heroes with spells that negate invisibility such as 
Bounty Hunter, Zeus and 
Slardar prevent her from saving her allies with Moonlight Shadow.
Mirana
* Overgrowth has a great duration, which prevents the units caught from attacking, moving and Blinking. Heroes like Storm Spirit, Mirana, Anti-Mage and others won't be able to do much if they're caught.
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
* 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.
Mirana
* Heroes with summons or illusions makes Sacred Arrow harder to land: Shadow Demon, Phantom Lancer, Nature's Prophet.
Mirana
* Heroes that rely on invisibility can be tracked with Charge of Darkness opening them to team attacks: Bounty Hunter, Mirana, Riki
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
* Heroes with a low health pool (Crystal Maiden, Skywrath Mage etc)
Mirana
* Heroes with summons or illusions makes Sacred Arrow harder to land: Shadow Demon, Phantom Lancer, Nature's Prophet.
Mirana
* Heroes with silences and hard stuns such as Doom, Silencer, and Lion can keep Mirana from Leaping away.
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.
Mirana
* Lion lacks mobility or escape mechanisms, making him an easy target for abilities like Mirana's Sacred Arrow or 
Leshrac's 
Split Earth, or combos like 
Kunkka's 
X Marks the Spot into 
Torrent.
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
* 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.
Skywrath Mage
* Heroes with high magical burst can easily kill Huskar when he is at low health: Lion, 
Lina, Skywrath Mage
Mirana
* Even though Luna is the kind of hero that Mirana can handle due to Moonlight Shadow rendering her safe from 
Eclipse with Moonlight Shadow, smart Luna can buy 
Dust of Appearance, allowing her to provide vision on her to her team, and possibly, kill Mirana.
* Luna's high movement speed allows her to evade Sacred Arrow, giving Mirana difficulties in hitting her with it.
* Aghanim's Scepter upgraded Eclipse combined with Dust of Appearance allows Luna to cast it on a hero that is struck by Sacred Arrow and/or after Mirana jumps in with Leap.
Additional:
* Even though Luna is the kind of hero that Mirana can handle due to Moonlight Shadow rendering her safe from Eclipse with Moonlight Shadow, smart Luna can buy Dust of Appearance, allowing her to provide vision on her to her team, and possibly, kill Mirana.
* Luna's high movement speed allows her to evade Sacred Arrow, giving Mirana difficulties in hitting her with it.
* Aghanim's Scepter upgraded Eclipse combined with Dust of Appearance allows Luna to cast it on a hero that is struck by Sacred Arrow and/or after Mirana jumps in with Leap.
Mirana
* A couple of long-range heroes with excellent laning like Mirana, Lina, Necrophos, 
Death Prophet. The key to success is sticking together and attacking Luna whenever she enters the range, without even giving Luna a chance to retaliate. Multiple long-range heroes is a reason to pick another hero.
Mirana
* 
Windrun quickly dodge Mirana's Sacred Arrow and misses her attacks.
* 
Shackleshot through tree with 
Focus Fire via Aghanim's Scepter combo can kill Mirana quickly, before using Leap or Moonlight Shadow.
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.
Mirana
* Sacred Arrow's long stun duration can prevent Morphling from casting his Waveform or Morph Replicate, making him unable to escape and easier to gank.
* Moonlight Shadow also allows Mirana's team to surprise Morphling while he tries to push towers.
* Mirana usually buys 
Linken's Sphere to protect herself from single-target abilities, making Morphling's Adaptive Strike and 
Ethereal Blade harder to use on her.
* However, Mirana also provides a chance to become a good Morph target, allowing Morph to use Leap to run away, if necessary.
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.
Mirana
* Leap allows Mirana to easily escape the freezing range of Cold Feet. Mirana also tends to build 
Manta Style which dispels Cold Feet.
* During Moonlight Shadow, the invisibility makes it hard to catch Mirana's team with Ice Blast.
* Ancient Apparition's lack of mobility/escape capabilities makes him an easy target for Mirana at any stage of the game.
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.
Mirana
* Heroes that can instantly kill creeps greatly reduce the effectiveness of Chen's converted army: 
Lifestealer, Doom, Mirana, 
Clinkz.
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.
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
* 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.
Mirana
* Techies spends lots of time standing still planting stacks of 
Land Mines away from creep waves.
* Sacred Arrow can be used to scout hidden Land Mines among trees and at uphill places. It can also be used to catch Techies while he's planting them.
* If Techies is hit with a Sacred Arrow, he can be killed before he has a chance to use 
Blast Off!.
* Mirana has a high attack range to destroy his traps from a safe distance.
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.
Mirana
* Sacred Arrow can be used to interrupt Freezing Field from a safe distance, forcing her to cancel it to dodge or get hit.
* Crystal Maiden has very slow movement speed, making her an easy Sacred Arrow target.
* Crystal Maiden has low health and can easily be killed with an Aghanim's Scepter combo or just when hit with an arrow.
* If 
Frostbite has already been used, Mirana can Leap away even when slowed by 
Crystal Nova or 
Freezing Field.
Mirana
* Mirana can use Leap to jump right next to Drow Ranger or can approach her while under cover of the invisibility granted by Moonlight Shadow, which cancels the bonus granted to Drow Ranger by 
Marksmanship.
* Her low health makes her easy to burst down with Mirana's spells, especially with Aghanim's Scepter.
* Mirana can dodge 
Gust with good reaction time, or Leap away if Drow tries to slow her without Gust.
Mirana
* Heroes that can protect or dispel stunned allies such as Legion Commander, Outworld Destroyer, Shadow Demon and Oracle can reduce the effectiveness of Sacred Arrow.
Mirana
* Heroes that cannot move in fights such as a 
Dueling Legion Commander or anyone channeling a spell like Bane, 
Pudge, or 
Enigma are easy Sacred Arrow targets.
Skywrath Mage
* Mystic Flare can easily burst down Legion Commander while she is Dueling.
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
* 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
* 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.
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.
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.
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
Mirana
* Mirana can disturb Shadow Shaman's channeling even if he is under the effect of invisibility thanks to Sacred Arrow.
* Mirana armed with an Aghanim's Scepter is known to be able to quickly burst down heroes - especially supports. Together with Ethereal Blade the bullying towards Shadow Shaman can continue for the whole match.
Mirana
* Sacred Arrow can be used to interrupt Death Ward from a safe distance, forcing him to cancel it to dodge or get hit.
* 
Paralyzing Cask is a slow-moving stun, and Mirana can Leap away from her allies to keep it from bouncing.
* Witch Doctor has low health and can easily be killed with an Aghanim's Scepter combo or just when hit with an arrow.
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.
Mirana
* Leap allows Mirana to easily escape Torrent and Ghostship.
Mirana
* Heroes that have an escape that doesn't disjoint projectiles: Mirana, 
Faceless Void, 
Magnus
Mirana
* Mirana can instantly kill creeps with Sacred Arrow, making her decent at crippling the armies of 
Chen or 
Enchantress.
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.
Skywrath Mage
* Heroes with high magical or pure damage will bypass Bulwark: 
Timbersaw, 
Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, Oracle.
Mirana
* Heroes that cannot move in fights such as a Dueling Legion Commander or anyone channeling a spell like Bane, Pudge, or Enigma are easy Sacred Arrow targets.
Skywrath Mage
* Skywrath Mage's Mystic Flare can deal huge damage to Clockwerk inside his Power Cogs.
Mirana
* Heroes that cannot move in fights such as a Dueling Legion Commander or anyone channeling a spell like Bane, Pudge, or Enigma are easy Sacred Arrow targets.
Additional:
* If Meat Hook is used before Leap, Mirana may be able to escape Pudge's grasp by leaping to safety.
* The invisibility from Moonlight Shadow gives a degree of mobility, which can make Mirana or her teammates difficult targets to hook.
* Sacred Arrow can be used to cancel Dismember from long distances.
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
* 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
* Heroes with powerful spammable abilities will prove problematic for Grimstroke as Ink Swell does not protect him from them: Zeus, Skywrath Mage, Tinker, Lina
Mirana
* Mirana can destroy Tombstone, and evade zombies using Leap and Moonlight Shadow's invisibility.
Mirana
* Any hero that can outrange Plague Ward can neutralize them without putting themselves at risk of receiving Poison Sting: 
Arc Warden, Chen, Clinkz, 
Drow Ranger, Lina, Mirana, Nature's Prophet, Pugna and 
Sniper.
* Special mention to heroes that outrange Plague Ward after obtaining talents that increase attack range.
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.
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.
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
* 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.
Mirana
* Heroes that have superior mobility that can easily catch up with Mirana even after she used Leap to escape: Anti-Mage, Queen of Pain, Storm Spirit, Riki.
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.
Mirana
* Heroes that have superior mobility that can easily catch up with Mirana even after she used Leap to escape: Anti-Mage, Queen of Pain, Storm Spirit, Riki.
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
* 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.
Mirana
* Heroes who rely on invisibility, such as Bounty Hunter, Clinkz, Mirana, Nyx Assassin and Riki, as they will be revealed if caught by Chronosphere.
Skywrath Mage
* Heroes that can easily kill Faceless Void from outside his Cronosphere; Sniper, Skywrath Mage, etc.
Mirana
* Low-health, normally mobile carries who rely entirely on raw attack damage are vulnerable to Bane's nukes and disables: Anti-Mage, Clinkz, Drow Ranger, Faceless Void, 
Gyrocopter, Juggernaut, 
Meepo, Mirana, 
Monkey King, Morphling, Phantom Assassin, Phantom Lancer, Riki, 
Shadow Fiend, 
Slark, Sniper, 
Terrorblade, 
Troll Warlord, Weaver.
Mirana
* Heroes that cannot move in fights such as a Dueling Legion Commander or anyone channeling a spell like Bane, Pudge, or Enigma are easy Sacred Arrow targets.
Mirana
* Heroes that have superior mobility that can easily catch up with Mirana even after she used Leap to escape: Anti-Mage, Queen of Pain, Storm Spirit, Riki.
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
