Enchantress
* 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.
Ancient Apparition
* Riki can get on top of Ancient Apparition very easily with 
Blink Strike. This can also double as a way to dodge Ice Blast, along with Tricks of the Trade.
* Ancient Apparition will frequently resort to casting Ice Blast right before dying. Smoke Screen can be used to prevent this, stopping Ancient Apparition from having any impact.
Enchantress
* Heroes with little health or magic resistance are easily picked off with Oracle's magic burst, such as 
Skywrath Mage, 
Crystal Maiden, or 
Enchantress.
Ancient Apparition
* 
False Promise can dispel the stun from Cold Feet and can save an ally that's about to shatter from Ice Blast, even allowing healing with 
Purifying Flames by delaying it until after the debuff expires.
* Purifying Flames allows Oracle to deny his allies if they're affected by Ice Blast. If he brings his allies' health to or below the shatter threshold, it will count as him denying the ally. However, this does not work on Oracle himself.
* 
Fate's Edict provides 100% magic resistance, making it good against all of Ancient Apparition's abilities at all stages of the game.
* 
Fortune's End can dispel Cold Feet from allies.
Additional:
* False Promise can prevent the shatter from 
Ice Blast and Fate's Edict can protect an ally from the magical damage over time for a while.
* Oracle can deny allies who are frostbitten. If he uses Purifying Flames to reach the shatter threshold, it will count as a deny.
* Fortune's End can dispel 
Cold Feet on affected allies, preventing them from getting frozen.
Enchantress
* Heroes with break can disable Untouchable for a while: 
Doom and 
Shadow Demon (via 
Aghanim's Scepter), 
Viper, 
Shadow Shaman with Hex Breaks talent.
Ancient Apparition
* 
Corrosive Skin minimizes the damage Viper takes from all of Ancient Apparition's abilities.
* Ancient Apparition's slow movement speed, squishy nature, and lack of escape abilities can easily be taken advantage of through 
Poison Attack and 
Viper Strike.
Enchantress
* 
Windrun's speed allows easy pursuit or escape, while the evasion greatly reduces the threat of Enchantress's Impetus, especially when retreating.
* 
Shackleshot is a powerful disable if Enchantress gets too close to one of her own minions.
* 
Focus Fire can negate 
Untouchable.
Ancient Apparition
* 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.
Enchantress
* Heroes with haste can negate Enchant's slow: 
Weaver, 
Dark Seer, 
Lycan, 
Centaur Warrunner.
Ancient Apparition
* 
Time Lapse allows Weaver (or an ally if upgraded with Aghanim's Scepter) to regain HP while affected by Ice Blast.
* 
Shukuchi completely ignores the slow from Ice Vortex and helps him escape the freeze range of Cold Feet.
Additional:
* Cold Feet is extremely easy to nullify with Shukuchi.
* 
Ice Vortex does not slow Weaver in Shukuchi.
* Time Lapse will still affect his health, even when hit by Ice Blast.
* Ancient Apparition has no escapes or saves and is very squishy, making him an easy target for Weaver to get on top of.
Enchantress
* 
Blade Fury dispels the slow from Enchant, and can burst Enchantress 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.
Additional:
* 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.
Ancient Apparition
* 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.
Enchantress
* 
Vendetta can deal great damage against her. However, it requires an direct attack, so Nyx Assassin may have difficulties applying Vendetta on her.
* Enchantress's lack of mobility makes her a primary target for ganking with Vendetta.
* 
Mind Flare can deal a great damage against her due to being an Intelligence hero.
* 
Spiked Carapace can reflect Impetus and stun Enchantress.
Additional:
* Spiked Carapace reflects the damage from 
Impetus.
* Enchantress is a rather squishy hero, making her fall easily to Nyx Assassin's high burst damage.
Ancient Apparition
* 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.
Enchantress
* Heroes that can jump on her: 
Slark, Queen of Pain, 
Anti-Mage
Ancient Apparition
* Anti-Mage can 
Blink away from Cold Feet or build a 
Manta Style to dispel it.
* 
Counterspell minimizes the damage Anti-Mage takes from all of Ancient Apparition's abilities.
* 
Mana Break and 
Mana Void deal a lot of damage to Ancient Apparition due to his high mana pool.
Additional:
* Anti-Mage easily Blinks out of Cold Feet's freeze radius.
* Ancient Apparition lacks mobility, thus making him fall easily to Mana Void.
* Counterspell reduces all Ancient Apparition's spell damage.
Enchantress
* Heroes with break can disable Untouchable for a while: Doom and Shadow Demon (via Aghanim's Scepter), Viper, Shadow Shaman with Hex Breaks talent.
Ancient Apparition
* 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.
Enchantress
* 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.
Ancient Apparition
* 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.
Enchantress
* Heroes that can jump on her: Slark, Queen of Pain, Anti-Mage
Additional:
* Queen of Pain often relies more on abilities than right-clicks, making Untouchable nearly useless against her.
* Enchantress also has a lower health pool than Queen of Pain, making her vulnerable to Queen of Pain's damage burst.
Ancient Apparition
* 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.
Enchantress
* Heroes with nukes: Bane, Lich, Lion, Skywrath Mage
Additional:
* 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 not as much effective against Lion's burst as it could be.
* Her raw movement speed is a fair escape/mobility mechanism, which may allow her to avoid a blindly cast 
Earth Spike, but does nothing against the rest of Lion's abilities, since they are single target and can't miss.
* Since Lion's damage comes mostly from his skills, Untouchable does nothing to mitigate it.
Ancient Apparition
* 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.
Enchantress
* All of Tinker's damage is magic/pure and completely ignores Enchantress's Untouchable. And Tinker's nukes can quickly decimate her small HP pool, sometimes even preventing Enchantress from even responding.
* As Enchantress relies solely on her primary attacks to deal damage, and rarely builds something to dispel it, Laser's Blind is particularly effective.
* However, Enchantress will probably build a Linken's Sphere against Tinker's Laser, so getting an additional disable is highly recommended.
Enchantress
* Magnetic Field makes Impetus miss; if Enchantress decides to enter the field, she is giving up bonus damage since Impetus deals greater damage at higher distance away from targets.
Enchantress
* Enchantress often has a small army of neutral creeps, allowing Medusa to hit her with a later bounce of her Mystic Snake.
Enchantress
* 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.
Ancient Apparition
* 
Dissimilate and 
Astral Step allow Void Spirit to quickly escape from Cold Feet.
* Void Spirit deals both magical and physical damage, which makes Ancient Apparition an easy target to ambush.
* If Void Spirit purchases Aghanim's Scepter, the silence provided by 
Resonant Pulse can disrupt Ancient Apparition during fights, as he is entirely reliant upon spells to contribute.
Ancient Apparition
* 
Primal Split makes Brewmaster invulnerable for the duration, rendering effects of Cold Feet and Ice Blast useless.
* 
Dispel Magic can dispel Cold Feet from allies.
* Brewmaster can easily run Ancient Apparition down with the slow from 
Thunder Clap and 
Cinder Brew.
Enchantress
* 
Battle Trance and 
Fervor can help Troll Warlord deal with Enchantress through 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.
Ancient Apparition
* Since Primal Beast is highly mobile with Onslaught alone, he will be difficult to catch with both Cold Feet and Ice Blast.
* Ice Blast is less effective due to Primal Beast's massive health pool and resistance to taking damage.
* While 
Chilling Touch can be used to slow Primal Beast briefly, it is not enough to beat him back, and can also contribute to his Uproar stacks.
* Primal Beast has a dispel talent at level 15 that will remove Cold Feet immediately when Uproar is used.
Enchantress
* 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.
Ancient Apparition
* As Ancient Apparition likes to stay far away from the fight to get full effectiveness from Ice Blast, he is a very good target for a 
Haunt gank.
* Ancient Apparition also has no hard disables and escape spells, making him an easy kill for Spectre.
Enchantress
* Enchantress has a very low health pool, allowing Zeus to burst her down quickly before she can heal off the damage with Nature's Attendants.
* 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 damage from Impetus.
* The exception is the laning phase, where Enchantress can gank Zeus if she Enchants a good creep.
Additional:
* 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.
Enchantress
* Mirana can instantly kill creeps with Sacred Arrow, making her decent at crippling the armies of 
Chen or Enchantress.
Ancient Apparition
* 
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.
Enchantress
* Heroes that have an escape that doesn't disjoint projectiles: 
Mirana, 
Faceless Void, 
Magnus
Enchantress
* Untouchable won't mitigate Venomancer's magical damage, and Enchantress is vulnerable to magic damage.
* Both 
Venomous Gale and 
Poison Nova lower the amount of healing received by Enchantress and her allies from Nature's Attendants.
Ancient Apparition
* 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.
Ancient Apparition
* Lone Druid's early game is good against slow, squishy supports since his bear is very strong early game and an Entangling Claws proc almost always guarantees a kill: 
Ancient Apparition, Crystal Maiden, Shadow Shaman, etc.
Ancient Apparition
* 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.
Enchantress
* Heroes with haste can negate Enchant's slow: Weaver, Dark Seer, Lycan, Centaur Warrunner.
Enchantress
* Heroes with nukes: Bane, Lich, Lion, Skywrath Mage
Enchantress
* Sand King is a strong ganker, allowing him to shut down squishy heroes in the early game: Phantom Assassin, 
Clinkz, 
Sniper, Enchantress.
Enchantress
* Heroes with nukes: Bane, Lich, Lion, Skywrath Mage
Enchantress
* Heroes with haste can negate Enchant's slow: Weaver, Dark Seer, Lycan, Centaur Warrunner.
Enchantress
* Heroes with break can disable Untouchable for a while: Doom and Shadow Demon (via Aghanim's Scepter), Viper, Shadow Shaman with Hex Breaks talent.
Ancient Apparition
* Ancient Apparition has no escape or reliable control and is very fragile, which makes him an easy target for anyone who can get on top of him, like Phantom Assassin or Clinkz.
Ancient Apparition
* 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.
Ancient Apparition
* 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.
Additional:
* Ancient Apparition's only skill to stop Storm Spirit is Cold Feet, which is bad in general when trying to stop a Storm Spirit without any other disable.
* As a fragile support with low Strength gain and no magic resistance, Ancient Apparition is vulnerable to Storm Spirit's combos.
Enchantress
* Heroes with haste can negate Enchant's slow: Weaver, Dark Seer, Lycan, Centaur Warrunner.
Ancient Apparition
* 
Shapeshift increases Lycan's movement speed and renders him unslowable, allowing him to easily avoid and escape Ancient Apparition's abilities.
* Lycan has fast summons, both his wolves from 
Summon Wolves can do heavy damage to Ancient Apparition due to his immobility and low armor.
Enchantress
* Lycan relies heavily on right clicks making Untouchable very effective against him.
* If he tries to run away Impetus will do huge amounts of damage.
Additional:
* She can Enchant one of the wolves to her side.
* Lycan will struggle greatly to harm Enchantress through her Untouchable which can seriously slow down Lycan's attack speed even if Lycan is spell immune.
Ancient Apparition
* Squishy heroes, usually supports, like Lion, Ancient Apparition, 
Keeper of the Light etc can die quickly to Tiny's magic burst.
Ancient Apparition
* 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.
Ancient Apparition
* Fragile supports with low armor are always a good prey, also her Psionic Trap will wear down most attempts to flee with their built-in disables: Silencer, Crystal Maiden, 
Warlock, Ancient Apparition, 
Grimstroke, 
Witch Doctor
Enchantress
* 
Doom with the {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent} talent can be useful against heroes with troublesome passive skills while also disabling them for a long time: Phantom Assassin, Enchantress, 
Huskar, 
Underlord.
Additional:
* 
Devour can easily eat creeps controlled by Enchant, limiting her ganking potential.
* Doom reduces the amount of healing received by Enchantress and her allies from Nature's Attendants. In addition, when Doom chooses the Doom applies Break talent, it can also disable Untouchable.
Enchantress
* Heroes with nukes that can jump her: 
Clockwerk, 
Snapfire, Spirit Breaker, 
Techies
Additional:
* Techies does huge amounts of magical damage, which will bypass Untouchable.
* Enchantress depends on abilities to do damage and heal, which Blast Off's silence prevents.
Ancient Apparition
* For the same reason, he has to be slightly more cunning when playing against heroes that can scout the treeline, such as Ancient Apparition and his Ice Vortex and Shadow Demon and his 
Shadow Poison.
Enchantress
* 
Meepo can quickly kill Enchantress with a 
Poof combo, rendering Untouchable useless.
Enchantress
* Enchantress's Untouchable slows down Meepos attacks and Impetus can deal heavy pure damage to a single Meepo, however once Meepo has closed the gap she is an easy target for Poof.
Ancient Apparition
* 
Icarus Dive helps Phoenix escape from Cold Feet.
* However, all of Pheonix's basic abilities do cost health, which can be harmful under the effects of Ice Blast.
* 
Supernova can save Phoenix from Ice Blast.
Additional:
* Supernova with or without Aghanim's Scepter allows to save ally or himself through Ice Blast.
* Icarus Dive quickly escapes from Cold Feet.
Ancient Apparition
* Since all of Phoenix's abilities (except for Supernova) have health costs, heroes like Ancient Apparition or 
Necrophos can turn Phoenix's abilities against it. However, Supernova does completely protect Phoenix from Ice Blast.
Ancient Apparition
* 
Sunder allows Terrorblade (or an ally) to regain HP while affected by Ice Blast.
* Terrorblade often buys Manta Style which can dispel Cold Feet.
Additional:
* Sunder is not affected by Ice Blast and will still swap health with any target as usual.
Enchantress
* Heroes that can dominate his illusions or create their own illusions of him: Dark Seer, 
Morphling, Enchantress, Shadow Demon, Grimstroke with Aghanim's Scepter.
Ancient Apparition
* Phantom Lancer can dispel or escape from Cold Feet with 
Doppelganger and 
Phantom Rush, respectively. Phantom Lancer also frequently builds a Manta Style which dispels Cold Feet.
* Ancient Apparition has trouble dealing with Phantom Lancer's illusions due to a lack of Area of Effect damage other than Ice Blast.
* Phantom Lancer tends to build a Diffusal Blade, which greatly amplifies his damage against Ancient Apparition due to Ancient Apparition's high mana pool.
* Ancient Apparition has no escape/mobility mechanisms, making him an easy target for Phantom Lancer at any stage of the game.
Ancient Apparition
* Ancient Apparition's Ice Blast will only debuff Phantom Lancer and not his illusions.
* Heroes with undispellable debuffs will help identify the real Phantom Lancer through visual effects or debuff indicators, provided that it was cast on the real Phantom Lancer to begin with:
* Doom's Doom marks Phantom Lancer with a highly visible effect, and also silences and mutes him.
* 
Bloodseeker's 
Rupture shows a clear red trail effect on the real Phantom Lancer.
* Ancient Apparition's Ice Blast will only debuff Phantom Lancer and not his illusions.
* Grimstroke's 
Soulbind is undispellable.
* Shadow Demon's 
Demonic Purge is undispellable.
* 
Monkey King's 
Jingu Mastery is undispellable and puts a big yellow Mark over his head.
Enchantress
* Heroes with nukes that can jump her: Clockwerk, Snapfire, Spirit Breaker, Techies
Ancient Apparition
* 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.
Enchantress
* 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.
Enchantress
* Enchantress can turn Chen's own creeps against him with Enchant. The creeps still keep the health buff Holy Persuasion granted them. 
Aghanim's Shard gives Enchantress 
Little Friends ability, which allows her to turn multiple of Chen's creeps all at once against him.
* Untouchable and Nature's Attendants make her difficult to kill.
Additional:
* Even though Chen can use 
Holy Persuasion on creeps controlled by Enchant, Enchantress can also use Enchant on Chen's creeps, making it somewhat of a double-edged sword type of matchup.
* Aghanim's Shard gives Enchantress Little Friends ability, which she can use to turn all of Chen's creeps against him for a short time when casted on him.
* Impetus's high burst damage can often kill any of Chen's allies before he can save them with 
Hand of God.
Ancient Apparition
* Ice Blast prevents 
Divine Favor and Hand of God from healing his allies or himself.
Additional:
* Ice Blast can prevent healing from Hand of God and kill Chen's creeps.
* Ancient Apparition can easily harass Chen on lane with Chilling Touch due to it's high range and damage. This can get even worse if Ancient Apparition buys Aghanim's Scepter and combines it with items that can give him bonus attack damage and attack speed.
* Chilling Touch combined with Ice Vortex makes it impossible for Chen to escape from Cold Feet. Ice Vortex can also make Chen's creeps more vulnerable to Ancient Apparition and his allies's magical damage.
Enchantress
* Untouchable makes it near impossible to stack Burning Spears.
* Impetus' pure damage puts an instant end to Huskar's low-health brinkmanship.
Ancient Apparition
* Ice Blast prevents Huskar from healing with 
Berserker's Blood and negates any lifesteal, making him significantly weaker in battle.
* 
Burning Spear and 
Life Break cost Huskar his own health, killing him under the effects from Ice Blast.
* Huskar often builds 
Armlet of Mordiggian which can be deadly during Ice Blast.
Additional:
* Ice Blast prevents Huskar from healing, regeneration, health gained from activating an Armlet of Mordiggian and will kill him when his health dips below a threshold. This makes it very dangerous for him to use his abilities.
Enchantress
* Untouchable greatly reduces Chemical Rage's attack speed advantage.
Ancient Apparition
* Ice Blast cancels out Chemical Rage's rapid health regeneration. It can also take advantage of Alchemist's Armlet of Mordiggian toggling, as it will make HP drain insanely fast, essentially killing the bearer in no time.
Additional:
* Ice Blast nullifies the health regeneration granted by 
Chemical Rage, which Alchemist greatly relies on to stay alive in battle.
* Alchemist tends to build Armlet of Mordiggian which can be deadly during Ice Blast.
Enchantress
* Since Untouchable pierces Spell Immunity, Lifestealer cannot burst her down even with 
Rage; meaning she can heal herself back to full HP.
Ancient Apparition
* Ice Blast prevents Lifestealer from lifestealing and healing with Infest in fights.
Enchantress
* Impetus is not blocked by 
Guardian Angel. A {U:Satyr Banisher} can also be controlled to dispel Guardian Angel.
Additional:
* Enchantress's Impetus deals pure damage instead of physical damage and ignores Guardian Angel, thus fully negating one of Omniknight's most important abilities for teamfights.
* Similar to Doom, Enchantress can use Enchant on Satyr Banisher, which will give her access to Satyr Banisher's 
Purge, and allow her to remove Heavenly Grace and Guardian Angel.
Ancient Apparition
* Heroes with large magical AoE damage will fare well against Omniknight: Lich, Ancient Apparition, 
Jakiro, 
Disruptor.
Enchantress
* Untouchable negates Inner Beast's attack speed bonus, making her hard to kill even if stunned by Primal Roar.
* Enchantress can also take control of Beastmaster's summons.
Additional:
* Enchant can control Beastmaster's boars with Enchant, mitigating his effectiveness during the laning stage and teamfights.
Ancient Apparition
* Ice Blast stops Morphling from gaining additional health with 
Attribute Shift.
* Using Attribute Shift would even bring Morphling closer to the shatter threshold.
* In the lane, Ice Vortex slows Morphling's already poor movement speed to a crawl; this, coupled with the amplification of magic damage, can set up an early kill on Morphling if Ancient Apparition has a suitable lane partner.
Additional:
* Ice Blast stops Attribute Shift (Strength Gain) from recovering adional health, and using it will even bring Morphling closer to the shatter threshold.
* In lane, Ice Vortex slows Morphling's already poor movement speed to a crawl; this, coupled with the amplification of magic damage, can set up an early kill on Morphling if Ancient Apparition has a suitable lane partner.
Ancient Apparition
* Muerta doesn't have the speed to easily escape Cold Feet, potentially controlling her during Pierce the Veil.
* Ancient Apparition outranges Muerta with Chilling Touch, allowing him to poke her down safely.
Enchantress
* Impetus pure damage ignores the extra armor granted from Wukong's Command.
* Enchant can dispel Monkey King's Jingu Mastery bonuses.
* Untouchable makes it hard for Monkey King to land Jingu Mastery stacks.
* 
Sproink allows Enchantress to escape from Wukong's Command.
Ancient Apparition
* 
Shallow Grave prevents Ice Blast's shatter for up to 5 seconds, but can mostly only delay it as Ice Blast's debuff lasts 10 seconds and prevents 
Shadow Wave from healing them.
Additional:
* Ice Blast negates healing from Shadow Wave, and lasts longer than Shallow Grave.
Enchantress
* Untouchable will significantly slow down Chaos Knight's physical damage with Phantasm.
* Impetus deals double damage to illusions, making it effective against Phantasm.
Additional:
* Untouchable makes all of Chaos Knight's attacks slow therefore he is unable to deal damage, especially his critical damage of 
Chaos Strike, also enables Enchantress to escape easily from his attacks.
* However, 
Reality Rift can still pose a danger to Enchantress because Chaos Knight can decrease a good amount of armor, making it dangerous because of her little armor stat, as he can burst down Enchantress easily if any of Chaos Knight's allies can apply a break on Enchantress.
Ancient Apparition
* Ice Blast completely nullifies any healing, making Necrophos unable to stay in a teamfight to sustain his teammates (and himself) or deal gradual damage to the enemy, else he be faced with a quick death if focused on.
Ancient Apparition
* Ice Blast prevents Death Prophet from gaining health from 
Spirit Siphon and 
Exorcism.
Additional:
* Ice Blast prevents Death Prophet from gaining health from Spirit Siphon and Exorcism.
* However, there is a way for Death Prophet to counter Ice Blast: Since Death Prophet is not healed until the spirits are returned to her. She can attempt to outrun her spirits to delay their return until Ice Blast duration runs out.
Ancient Apparition
* Ice Blast prevents Io from healing an ally with 
Tether and prevents healing from 
Overcharge
* Io is a common 
Mekansm builder which is useless if he is affected by Ice Blast.
Additional:
* Ice Blast prevents Io from healing the target.
* Ancient Apparition can easily harass Io on lane with Chilling Touch due to it's high range and damage. This can get even worse if Ancient Apparition buys Aghanim's Scepter and combines it with items that can give him bonus attack damage and attack speed.
* Chilling Touch combined with Ice Vortex makes it nearly impossible for Io to escape from Cold Feet. Ice Vortex can also make Io and it's tethered target more vulnerable to Ancient Apparition and his allies's magical damage.
Enchantress
* Against her Untouchable, Sven is barely able to hit Enchantress even with his 
Black King Bar.
Enchantress
* Impetus will deal huge amounts of damage when he uses a 
Fire Remnant to escape.
* 
Flame Guard is useless against Impetus as it deals Pure damage.
* Enchant can be used to dispel Flame Guard.
Ancient Apparition
* 
Cold Embrace makes its target immovable, allowing Ancient Apparition to easily land Ice Blast, or a Cold Feet stun.
* Ice Blast also negates healing from Cold Embrace.
Additional:
* Ice Blast disables the healing component of Cold Embrace, making it essentially a 4 second stun on an ally and a perfect setup for Ice Blast.
* If Cold Feet is cast on an Allied hero affected by Cold Embrace, it will almost guarantee the Ally comes out stunned.
Enchantress
* Untouchable makes her heavily reduce Elder Titan's physical damage output on her without Spell Immunity.
* Enchant can purge 
Astral Spirit's buff without Spell immunity.
* Nature's Attendants can protect her if she survives the full combo and manages to juke around.
Enchantress
* Enchant can dispel 
Overpower.
* Enchant's slow can help kite Ursa in fights and also in lane.
* Enchantress can out harass Ursa in lane by using her long attack range and Untouchable, as well as out sustaining him with Nature's Attendants.
Ancient Apparition
* Ice Blast's nullifies Abaddon healing from Borrowed Time and Mist Coil and it is not dispelled by Aphotic Shield.
Additional:
* Ice Blast nullifies 
Borrowed Time's and 
Mist Coil's healing.
Ancient Apparition
* Heroes that withstand damage like 
Timbersaw, 
Bristleback, 
Dragon Knight and others will have their durability largely reduced when hit by an Ice Blast due to the risk of shattering.
Enchantress
* Heroes that have an escape that doesn't disjoint projectiles: Mirana, Faceless Void, Magnus
Ancient Apparition
* Heroes that withstand damage like Timbersaw, Bristleback, Dragon Knight and others will have their durability largely reduced when hit by an Ice Blast due to the risk of shattering.
Additional:
* Cold Feet and Ice Vortex both hinder Dragon Knight's movement greatly during teamfights.
* Ice Blast ignores Dragon Knight's armor, disables his health regeneration, and kills him prematurely.
Enchantress
* Range-reliant heroes: Sniper, 
Drow Ranger
Enchantress
* Heroes that have an escape that doesn't disjoint projectiles: Mirana, Faceless Void, Magnus
Enchantress
* 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.
Additional:
* Though Enchantress's Untouchable can greatly reduce Luna's attack speed, and can go through any form of Spell Immunity, she has a pitiful HP so Lucent Beam and Eclipse can kill her very quickly.
* Moon Glaives allows Luna to clear Enchantress's creeps very efficiently.
Enchantress
* Heroes that create illusions: 
Spectre, Shadow Demon, 
Phantom Lancer, 
Naga Siren, 
Chaos Knight, 
Terrorblade) or bring other units into the fight (such as 
Nature's Prophet, 
Lone Druid, Chen, Enchantress, Meepo and 
Arc Warden) can cause Eclipse to strike the illusions/summons unintentionally. However, in many cases Moon Glaives can resolve this issue and eliminate them before activating Eclipse, but that will require lots of farming for right-click items.
Ancient Apparition
* Despite Ancient Apparition's fragileness, he can easily harass Luna on lane with Chilling Touch due to it's high range and damage. This can get even worse if Ancient Apparition buys Aghanim's Scepter and combines it with items that can give him bonus attack damage and attack speed.
* Chilling Touch combined with Ice Vortex can make it difficult for Luna to escape from Cold Feet
* Ice Blast can nullify any healing Luna receives and any attempt for her to save herself with 
Satanic, even through Black King Bar.
* For the same reasons, Ancient Apparition makes a very powerful ally for Luna when they are in the same team.
Enchantress
* Range-reliant heroes: Sniper, Drow Ranger
Ancient Apparition
* Heroes like Slark, Witch Doctor and others also tend to suffer in Ice Blast's heal denial.
Ancient Apparition

Zeus, Invoker,

Enchantress
* Heroes with nukes that can jump her: Clockwerk, Snapfire, Spirit Breaker, Techies
Ancient Apparition
* Snapfire is vulnerable while she is casting 
Mortimer Kisses making her an easy target for the effects of Cold Feet and Ice Blast.
Additional:
* Ice Blast, Cold Feet, and Ice Vortex are easier to land on Snapfire while she channels her Mortimer Kisses.
Enchantress
* 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.
Ancient Apparition
* Cold feet can be used to ensure that the full channel of Freezing Field doesn't go off.
Ancient Apparition
* Ancient Apparition has no escape or reliable control and is very fragile, which makes him an easy target for anyone who can get on top of him, like Phantom Assassin or Clinkz.
Enchantress
* Untouchable prevents Clinkz from harassing Enchantress in lane by lowering his attack speed.
* Nature's Attendants helps Enchantress to sustain through Clinkz's harassment in lane.
Enchantress
* 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.
* Bear in mind, however, that Timber Chain can also work against Timbersaw if used to escape and that Impetus can ignore 
Reactive Armor if Enchantress is not a primary target for Timbersaw or if he is disabled.
* Timbersaw is a common wielder of 
Lotus Orb, which will allow him to reflect Enchant back at Enchantress and dispel most debuffs as well.
Enchantress
* Timbersaw has a difficult time against magical and pure damage: Lina, 
Leshrac, Enchantress, Queen of Pain
Ancient Apparition
* Heroes that withstand damage like Timbersaw, Bristleback, Dragon Knight and others will have their durability largely reduced when hit by an Ice Blast due to the risk of shattering.
Enchantress
* Heroes that can jump on her: Slark, Queen of Pain, Anti-Mage
Ancient Apparition
* Heroes like Slark, Witch Doctor and others also tend to suffer in Ice Blast's heal denial.
Additional:
* Ice Blast stops Shadow Dance's passive health regeneration, even when Slark is not in vision.
Enchantress
* Enchant can not control golem 
Chaotic Offering from Warlock.
Ancient Apparition
* Ice Blast cancels Warlock's Golem's and Shadow Word's healing.
* Cold Feet stuns Warlock if he stands in place, forcing him to stop channeling Upheaval immediately or be forced to stop channeling it by it's stun.
Enchantress
* Heroes with nukes that can jump her: Clockwerk, Snapfire, Spirit Breaker, Techies
Ancient Apparition
* Ancient Apparition's Cold Feet will freeze Clockwerk in place if he stays inside his Power Cogs. His immobility while in his cogs also makes him a very easy target to Ice Vortex and Ice Blast.
Enchantress
* Enchantress's lack of area-of-effect abilities allows Broodmother to swarm her with Spiderlings.
* 
Spawn Spiderlings can kill enchanted creeps and create Spiderlings in their place.
* However, bear in mind that Untouchable makes it harder for Broodmother to actually hit Enchantress, even if Broodmother is spell immune. And Broodmother's only way to counter this is either by buying Silver Edge, buying items that deal high magical damage like 
Dagon, or by buying items that give high attack speed like 
Moon Shard.
Additional:
* Enchantress can be easily overwhelmed with Broodmother's spiderlings from Spawn Spiderlings and Enchantress can only control one of them with Enchant and she has no good waveclear (Spawn Spiderlings can also kill creeps controlled with Enchant).
* However, Untouchable's attack speed reduction can make it difficult for Broodmother to kill Enchantress even with any form of spell immunity.
Ancient Apparition
* Ice Blast prevents 
Insatiable Hunger lifesteal, 
Spin Web regeneration and quickly kills spiderlings.
Enchantress
* Enchantress has a very small health pool and cannot tank Lina's heavy magic burst.
Fiery Soul, exposing Enchantress's weakness to physical damage due to her low armor.
Untouchable is decently countered by Fiery Soul, exposing Enchantress's weakness to physical damage due to her low armor.
* Untouchable is decently countered by
* Lina is decent at clearing creeps and can kill Enchantress's creeps quickly.
Additional:
* Enchantress has pitiful health, and cannot tank Lina's heavy magic damage.
*
* Lina is decent at clearing creeps and can kill Enchantress' creeps quickly.
Ancient Apparition
* Lina builds
Shadow Blade (and upgrades it into a 
Silver Edge), which makes it hard for Ancient Apparition to land his abilities.
* Laguna Blade can kill Ancient Apparition easily due to his low health pool and lack of mobility.
