* Arc Warden can't use Magnetic Field to stall the damage of Nether Blast on towers, but he can buy Aghanim's Shard 20 minutes into the game to diminish its damage
* Arc Warden has no innate disables to stop Life Drain and Decrepify
* The short cooldown of both Life Drain and Decrepify also means Pugna can deal with Arc Warden and Arc Warden's clone simultaneously most of the time
* A good Pugna looks to end the match early while Arc Warden, a very item reliant hero, thrives in longer matches.

* Amazingly, Enchantress has even lower health than Pugna. Though she does pack quite a punch through Impetus, she can't use it if she is under Decrepify.
* Pugna's Magical DPS is way greater than the heal from Nature's Attendants, which will also harm her quite a bit if she's next to Nether Ward.

* Smoke Screen combined with Diffusal Blade leaves Arc Warden effectively useless for a while as he struggles to escape the silence with low mobility.
* With Arc Warden's low mobility, Tricks of the Trade often deal decent damage to him before he moves out of it.

* Riki usually buys Diffusal Blade to initiate, which renders Enchantress' movement speed useless, and is usually followed with Smoke Screen.
* Riki can effectively hit Enchantress by Tricks of the Trade alongside with Diffusal Blade and Smoke Screen's initiation. For a hero like Enchantress, 3 to 4 hits from Riki is a big deal, unless Enchantress built Force Staff earlier.

* None of Arc Warden's abilities are very effective against Broodmother and her spiderlings.
* A good Broodmother looks to end the match early while Arc Warden, a very item reliant hero, thrives in longer matches.
* Arc Warden has no innate disables to stop Broodmother from lifestealing with Insatiable Hunger and shredding through his relatively lower armor.

* Enchantress is well known for taking control of various summons with her Enchant. However, Broodmother's summons are not a good target for that, because she can swarm up a bunch of her summons with Spawn Spiderlings and Enchantress has no good waveclear (Spawn Spiderlings can also kill creeps controlled with Enchant).
Additional:
* Enchantress' lack of AoE abilities allows Broodmother to swarm her with Spiderlings.
* Spawn Spiderlings can kill enchanted creeps.

* Anti-Mage Blinks directly into Magnetic Field, bypassing its protection.
* Anti-Mage's high mobility allows him to deal with Tempest Double while it is split-pushing.
Additional:
* Arc Warden's high reliance on casting abilities leads him to be dependent on mana, which Anti-Mage can quickly burn with Mana Break.
* Blink mitigates the threat of Flux slow and allows Anti-Mage to close the distance between himself and Arc Warden.
* Anti-Mage's ability to farm quickly allows him keep up with Arc Warden's farm while also de-pushing the lanes Arc Warden shoves in with his Tempest Double.
* Anti-Mage also frequently buys Manta Style, and can use it so dispel Arc Warden's items that can threaten an Anti-Mage like Bloodthorn.
* Counterspell significantly reduces the effectiveness of Arc Warden's magical damage.
* However, do keep in mind that when Arc Warden has a Black King Bar, jumping him alone may not be the best idea as it puts you in a bad position, while Arc Warden summons his doubles and rain damage into you.

* Heroes that can jump on her: Slark, Queen of Pain, Anti-Mage

* Chain Frost can deliver high amounts of damage to Arc and his clone

* Heroes with nukes: Bane, Lich, Lion, Skywrath Mage

* Flux is dispelled by Dark Pact.
* Pounce allows Slark to avoid Spark Wraiths.
* Tempest Double allows Slark to build up Essence Shift stacks, especially when it is being used for split pushing.

* Heroes that can jump on her: Slark, Queen of Pain, Anti-Mage

* Heroes with haste can negate Enchant's slow: Weaver, Dark Seer, Lycan, Centaur Warrunner.

* He can't take you very easily, and his nukes are not strong enough to deal with Centaur Warrunner.
* Centaur Warrunner deals huge AoE damage and applies an AoE disable through Hoof Stomp, affecting the double as well the main Arc Warden.
* Magnetic Field is not very effective against melee heroes.
* This ability also increases his allies' attack speed, meaning Retaliate will deal more damage.
* Stampede catches him easily due to the lack of escape mechanisms.

* Heroes with break can disable Untouchable for a while: Doom and Shadow Demon (via Aghanim's Scepter), Viper

* Arc Warden relies on items and abilities, as well as his Tempest Double, to deal damage to enemies. Doom effectively denies that and makes Arc Warden useless in fights.

* A well-timed use of The Swarm provides vision over heroes with high mobility: Anti-Mage, Arc Warden, Dark Seer.

* Heroes with haste can negate Enchant's slow: Weaver, Dark Seer, Lycan, Centaur Warrunner.

* Song of the Siren stops Arc Warden from acting and allows Naga Siren's team to close in on him, past his Magnetic Field.
* Mirror Image dispels Flux. The illusions created from it also disable the slow from Flux if Arc Warden casts it after Mirror Image.
* Arc Warden's playstyle heavily favors split-pushing, which Naga Siren can compete against with her illusions.
Additional:
* Her Mirror Image illusions can depush the lanes pushed by the Tempest Double, relieving the pressure.
* Mirror Image dispels Flux, and the illusions stop Flux from working.

* Flux is paused if even one illusion remains near Phantom Lancer. It can also be dispelled with Doppelganger.
* Phantom Lancer can also easily dodge an activated Spark Wraith, or use his illusions to trigger it safely.
* Phantom Rush allows Lancer to quickly close gap to get inside of Arc Warden's Magnetic Field.
* Phantom Lancer and his clones are able to quickly drain Arc Warden of his mana with a Diffusal Blade. This means Warden's Tempest Double will also be summoned without mana.
Additional:
* Doppelganger dispels Flux.
* Phantom Rush closes the distance between Phantom Lancer and Arc Warden.
* Juxtapose overwhelms Arc Warden and nullifies his kit which is only effective against isolated enemies.

* Enchantress has a very low health pool, allowing Zeus to burst her down quickly before she can heal off the damage.
* Zeus will not be affected by Untouchable, as he won't try to attack her with right clicks anyway.
* Zeus can stay out of her attack range while trying to kill her, especially if he has bought an Aether Lens.
* Most heroes would want to get on top of Zeus to kill him, but Enchantress does not have this option as doing so would severely limit her Impetus damage.
* The exception is the laning phase, where Enchantress can gank Zeus if she Enchants a good creep.

* Blade Fury dispels the slow from Enchant, spell immunity and used to burst her down during the early laning stage.
* Omnislash and Swiftslash's physical damage burst ignore Untouchable.
* Silver Edge is an ideal item for Juggernaut to deal with Untouchable, making her vulnerable to melee attacks.
Additional:
* Blade Fury dispels the slow from enchant, and can burst her down during the laning stage.
* Omnislash and Swiftslash's physical damage burst ignore untouchable.
* Silver Edge is a common item for Juggernaut for dealing with Untouchable.

* Vendetta breaks Untouchable and deals great damage against her.
* Enchantress' lack of mobility makes her a primary target for ganking with Vendetta.
* Spiked Carapace can reflect Impetus and stun Enchantress.
* Mana Burn can deal tremendous damage against her due to being an Intelligence hero.
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.

* Untouchable doesn't work against Unleash, as Marci gains 1000+ attack speed for the fury combo.
* Enchantress' low health makes her a fragile target for Marci's damage blasts.
* Marci can use Rebound on one of her enchanted creeps to easily reach the Enchantress and negate the bonus damage dealt by her Impetus. It helps that most of her best creeps have a low attack range, creating a makeshift bridge towards their master.

* Static Link 's damage instants fully ignore Untouchable, combine with Eye of the storm and high movement speed compare to Enchantress with no mobility, Razor can easily take away her squishy health pool.

* Storm Spirit can hunt down Arc Warden with his Ball Lightning and kill him quickly due to his lack of escape abilities.
* None of his abilities are effective against Storm Spirit, as they can be evaded with Ball Lightning.

* Battle Trance and Fervor can help cancel out Untouchable.
Additional:
* Untouchable's attack speed slow is easily remedied by Fervor stacks and Battle Trance.
* Troll Warlord is a natural Silver Edge carrier, disabling Enchantress' Untouchable.

* Windrun's speed allows easy pursuit or escape, while the evasion greatly reduces the threat of Enchantress' Impetus, especially when retreating.
* Shackleshot is a powerful disable if Enchantress gets too close to one of her own minions.
* Focus Fire negates Untouchable.

* His Forge Spirit can negate Flux.
* Provided he does a right combo with Chaos Meteor, Invoker can easily burst down Arc Warden (plus his clone if he spawns it.)
* An early Orchid Malevolence can shut down Arc Warden pretty hard, especially when Invoker has a good lane against him if he kills him early on.
* Deafening Blast and Ice Wall limit's Arc Wardens mobility and damage, crippling him greatly.

* Enchantress has pitiful health, and cannot tank Lina's heavy magic damage.
* Untouchable is decently countered by Fiery Soul, exposing Enchantress' weakness to physical damage due to her low armor.
* Lina is decent at clearing creeps and can kill Enchantress' creeps quickly.
Additional:
* Enchantress has a very small health pool and cannot tank Lina's heavy magic burst.
* Untouchable is decently countered by Fiery Soul, exposing Enchantress' weakness to physical damage due to her low armor.
* Lina is decent at clearing creeps and can kill Enchantress' creeps quickly.

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

* Arc Warden's Flux is meaningless against Meepo who loves to group up. Meepo is also a very good gap closer, so Arc Warden's Magnetic Field becomes useless.

Additional:
* Flux is severely impaired against Meepo because of Divided We Stand.
* Meepo's farming speed and early powerspikes allows him to pressure Arc Warden before he is capable of fighting effectively.
* Without Black King Bar, Earthbind and Poof can finish Arc Warden quickly before he has time to do much.

* Meepo can quickly kill Enchantress with a Poof combo, rendering Untouchable useless.

* Chen in the early game is a faster pusher than Arc Warden until Arc Warden buys Maelstrom.

* Chen can use Holy Persuasion on creeps controlled by Enchant.
* Ironically, Enchantress can Enchant Chen's creeps.

* Luna's Moon Glaives allow her to clear Arc Warden's Tempest Double.
* Luna's short range and fast movement speed allow her to fight Arc Warden inside his Magnetic Field.

* Enchantress has pitiful HP so Lucent Beam and Eclipse can kill her very quickly.
* Moon Glaives allows Luna to clear Enchantress' creeps very efficiently.
Additional:
* Enchantress has pitiful HP, even more pitiful than Luna, so Lucent Beam and Eclipse will often harass and/or kill her through her Untouchable.
* With Moon Glaives, Luna can clear Enchantress's creep wave efficiently.

* Magnetic Field is useless against melee heroes, so Lycan can attack Arc Warden without missing.
* Flux doesn't affect Lycan that much, because Shapeshift grants immunity to slows and because he is never alone.
* If their Tempest Double has been called, Lycan can still kill Arc Warden before the double expires.

* Heroes with haste can negate Enchant's slow: Weaver, Dark Seer, Lycan, Centaur Warrunner.

* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, Enchantress, Gyrocopter, Lion, Riki, Techies, Terrorblade, Necrophos, Invoker.

* Heroes with nukes: Bane, Lich, Lion, Skywrath Mage

* Sand King is a strong ganker, allowing him to shut down squishy heroes in the early game: Phantom Assassin, Clinkz, Sniper, Enchantress,...

* Heroes with haste can negate Enchant's slow: Weaver, Dark Seer, Lycan, Centaur Warrunner.

* Melee carries who usually buy an early Black King Bar, and have gap closing abilities can be good against the Arc Warden, such as Phantom Assassin , Sven with Aghanim's Scepter etc.

* 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.

* Heroes with little health or magic resistance are easily picked off with Oracle's magic burst, such as Skywrath Mage, Crystal Maiden, or Enchantress.

* Heroes with summons or illusions counter Flux, such as Beastmaster , Chen, or Shadow Demon.

* Heroes with break can disable Untouchable for a while: Doom and Shadow Demon (via Aghanim's Scepter), Viper

* Heroes with nukes that can jump her: Clockwerk, Snapfire, Spirit Breaker, Techies

* Heroes with nukes that can jump her: Clockwerk, Snapfire, Spirit Breaker, Techies

* Heroes with damage-over-time abilities will not only proc Bristleback's passive continuously, they will also do little harm to him when he is facing away from the source: Venomancer, Arc Warden

Additional:
* Arc Warden has relatively lower armor and mobility, which makes him an easy target to apply Quill Spray and Viscous Nasal Goo stacks.
* Arc Warden also does not like to build a Silver Edge as it takes a long time to build up and may slow down the timings for other important items needed in the game. (eg. an Orchid Malevolence versus a Storm Spirit)
* However, do note that in a game where your team has many jumping capabilities or good passives, like a Tidehunter or Spectre, a Silver Edge becomes incredibly valuable on Arc Warden as not only can he run away from the jumps, he effectively gets 2 breaks, and Bristleback may not be the best pick.

* Heroes with nukes that can jump her: Clockwerk, Snapfire, Spirit Breaker, Techies

* Heroes like Enchantress and Chen, or heroes that make use of Helm of the Dominator are weak to Crystal Maiden, as Frostbite can do wonders against Enchant, Holy Persuasion, or dominated creeps. Careful though, as an army of carefully controlled creeps (Enchantress and Chen) can hold many stuns that will cancel Freezing Field.

Additional:
* Frostbite does 1000 magical damage to Enchantress's creeps and roots them for 10 seconds, which hinders her ability to gank.

* Untouchable won't mitigate Venomancer's magical damage, and Enchantress is vulnerable to magic damage.
* Both Venomous Gale and Poison Nova lowers the amount of healing received by Enchantress and her allies from Nature's Attendants.

* Rolling Thunder hits Arc Warden, his Tempest Double and any allies through Magnetic Field.
* Rolling Thunder also causes Pangolier to take no damage from existing stacks of Flux as well as clear all Spark Wraiths on the way.

* The burst damage from Timbersaw's abilities is more than enough to deal with Enchantress and her creeps.
* Timbersaw doesn't rely on his physical attacks, which makes Untouchable useless against him.
* Timber Chain can close the gap between them and minimize damage from Impetus.
* Be aware, however, that Timber Chain could work against him if used to escape.
* However, Impetus can ignore Reactive Armor if Enchantress is not a primary target for Timbersaw or if he is disabled.
