* 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.

* Heroes with strong area-of-effect damaging and/or disabling abilities will be able to intercept Underlord and his team when they exit from Fiend's Gate: Luna's Aghanim's Scepter upgraded Eclipse, Dawnbreaker's Solar Guardian, Axe's Berserker's Call, Mars's Arena of Blood, Jakiro's Macropyre, Dual Breath and Ice Path, Naga Siren's Song of the Siren, Razor's Eye of the Storm and Plasma Field, Lina's Light Strike Array, Broodmother's Spinner's Snare from Aghanim's Scepter, Elder Titan's Earth Splitter and Echo Stomp, Alchemist's Unstable Concoction and Acid Spray, Queen of Pain's Sonic Wave, Dark Seer's Wall of Replica and Vacuum, Venomancer's Noxious Plague and Poison Nova from Aghanim's Scepter, Oracle's Fortune's End and Rain of Destiny from Aghanim's Shard, Bloodseeker's Blood Rite, Enigma's Black Hole and Midnight Pulse, Shadow Fiend's Requiem of Souls, Batrider's Aghanim's Scepter upgraded Flaming Lasso, Firefly, Flamebreak and Sticky Napalm, Ancient Apparition's Ice Blast, Sand King's Epicenter, Sand Storm and Burrowstrike, Gyrocopter's Call Down, Ember Spirit's Sleight of Fist, Death Prophet's Exorcism and Silence, Monkey King's Wukong's Command, Crystal Maiden's Freezing Field, Muerta's The Calling, Medusa's Stone Gaze, Zeus's Nimbus from Aghanim's Scepter. Dark Willow's Bramble Maze, Pangolier's Swashbuckle, Grimstroke's Soulbind, Ink Swell and Stroke of Fate, Earthshaker's Echo Slam and Fissure, Puck's Dream Coil and Waning Rift, Winter Wyvern's Winter's Curse, Magnus's Reverse Polarity.

* 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.

* 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.

* 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.

* Pierce the Veil does not prevent Primal Beast from using any of his spells to their fullest and is one of the few heroes that can disable her during her ultimate and a common Black King Bar purchase. She will also likely be fatal to herself if Primal Beast has a Blade Mail active.
* Gunslinger will be disabled if Primal Beast buys an Aghanim's Scepter.

* 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.

* Primal Beast has a massive healthpool making it very difficult to get through it with a nuke such as Eclipse or Lucent Beam.
* Primal Beast is faster than Luna, as one of her main ways to escape danger, is very problematic for her in the laning stage especially.
* His ultimate goes through debuff immunity, making Luna's Black King Bar less effective.
* Primal Beast commonly buys Blade Mail which is a big problem for a single target bursting hero like Luna.

* Ice Blast prevents Insatiable Hunger lifesteal, Spin Web regeneration and quickly kills spiderlings.

* While Broodmother can hide in the trees with Spin Web, Primal Beast's ability to trample trees down can give him an edge in catching her.
* Insatiable Hunger will not do much vs Primal Beast's onslaught of disables.
* While Silken Bola can slow Primal Beast down, it's not enough to stop Trample from doing more damage than Broodmother can do back.
* Spawn Spiderlings will be destroyed by Onslaught and Trample very easily.

* Cold feet can be used to ensure that the full channel of Freezing Field doesn't go off.

* Any hero with low mobility and max healthsuch as Silencer, Crystal Maiden etc.

* 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.

* Dark Pact, Shadow Dance and Depth Shroud will do nothing against Onslaught and Trample, as they are both ground area-of-effect spells.
* Primal Beast has a gigantic hitbox, which could be difficult for Slark to escape with Pounce should Primal Beast choose to block him. Pounce also does not completely prevent Primal Beast from trampling offensively, as he still has some room to move.
* Primal Beast has a huge health pool making it difficult to shed it with Essence Shift and may allow Primal Beast to build Uproar stacks against him very rapidly.
* If Primal Beast buys an Aghanim's Scepter he can also break Essence Shift from working on attacks which is a big part of Slark's damage output.

* Ice Blast prevents Lifestealer from lifestealing and healing with Infest in fights.

* Special mention to Lifestealer who can use Rage to prevent Trample damage, but Primal Beast's ultimate can still be casted during the spell.

* Heroes like Slark, Witch Doctor and others also tend to suffer in Ice Blast's heal denial.

* Heroes who cannot escape from Trample early might be easy first blood. Heroes like Witch Doctor and Omniknight should play very cautiously alone...

* Heroes with large magical AoE damage will fare well against Omniknight: Lich, Ancient Apparition, Jakiro, Disruptor.

* Heroes who cannot escape from Trample early might be easy first blood. Heroes like Witch Doctor and Omniknight should play very cautiously alone...

* 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.

* 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.

* 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.

* Magnus is not tanky and struggles against burst damage, something Primal Beast excels at in the early-to-mid game. Primal Beast is also able to out-damage Magnus's Empower and can even contribute to his Uproar stacks.
* Using Skewer to drag Primal Beast while he is trampling will count as movement and will trigger a rapid number of slams, which could prove lethal to Magnus.

* Sprout gets destroyed by Trample and Onslaught.

* Primal Beast is one of Sniper's greatest counters, as he has no real means of escape and is very squishy, especially in the early game. Sniper's potshots and Shrapnel can contribute to Primal Beast's Uproar and further make him tankier than he already is. Onslaught allows him to close the gap on Sniper at his own volition, and Trample can deal serious damage to his meager health pool.

* 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.

* 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.

* Primal Beast has multiple ways to cancel Life Drain very quickly.
* Pugna has a very low strength gain and as a support does not have much gold to buy health items, making him vulnerable to Primal Beast's onslaught of magical damage.
* Ironically, Decrepify actually just increases Primal Beast's damage on the targeted ally if Trample is activated. However, it can be used to slow him down and prevent any further Trample damage.

* Onslaught prevents all of Razor's abilities from being effective against him, especially in the laning stage.

* 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.

* 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.

* 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.

* 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.

* Illusion heroes will struggle against Primal Beast's area damage capability, such as Chaos Knight, Naga Siren, Terrorblade.

* 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.

* Heroes who rely on burst damage with magical damage will struggle to kill Primal Beast: Spirit Breaker, Gyrocopter, Leshrac

* 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.

* Illusion heroes will struggle against Primal Beast's area damage capability, such as Chaos Knight, Naga Siren, Terrorblade.

* Any hero who lanes very poorly will struggle with Primal Beast's potential snowball in the very early levels, like Keeper of the Light, Luna, Templar Assassin...

* 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.

* Heroes who have low or high armor but very high health will be difficult for drow to burst down quickly: Primal Beast, Axe, Centaur Warrunner.

* Heroes who rely on burst damage with magical damage will struggle to kill Primal Beast: Spirit Breaker, Gyrocopter, Leshrac

* Heroes with global abilities can give Legion Commander's opponent an edge in Duels from anywhere on the map: Nature's Prophet, Ancient Apparition, Zeus, Invoker, Treant Protector

* Long lockdown is a great way to deal with Axe to prevent Berserker's Call from being used, heroes such as Legion Commander, Beastmaster and Primal Beast are good examples of this.

Additional:
* Berserker's Call will be a stun for Primal Beast and not much else due to Trample making him unable to attack.
* Battle Hunger is neglitable because Primal Beast has a much bigger health than Axe, so he does not need to fear being slowed, or his other abilities including Counter Helix or even a Blade Mail.
* Getting Primal Beast low enough to use a successful Culling Blade can be very difficult due to his massive health advantage over most heroes.
* Not ability related but Primal Beast does not need to fear Axe in lane, as Trample, combined with Uproar and Onslaught will do a ton of damage even if Axe has a Vanguard.

* Hard carries who just want to farm and be left alone will not appreciate Primal Beast, heroes such as Medusa, Drow Ranger...

* 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.

* Primal Beast can use Uproar to tank a portion of Omnislash, making him much more likely to survive it. Primal Beast can also charge away from Omnislash using Onslaught as the spell ends.
* Blade Fury will never do more damage than Uproar once the stacks are activated.
* Primal Beast is very commonly buying items that are good against Juggernaut, such as Ethereal Blade and Heart of Tarrasque.
* Primal Beast has one of the few ultimates that can prevent Juggernaut from spinning away with a teleport.

* Phantom Assassin is known to be weak against bursts of magical damage, something Primal Beast excels at from the beginning of the game. He can use this to his advantage by constantly hunting Phantom Assassin down, especially if she is left alone to farm.
* Primal Beast is a good carrier of Ethereal Blade, Vanguard and Shiva's Guard all of which are very good against Coup de Grace and Phantom Strike.
* Even though Primal Beast does a lot of physical damage early on, later once Blur becomes more potent, she may find herself being overwhelmed by Trample and Onslaught instead.
* Primal Beast's ultimate goes through spell immunity and his level 25 talent makes it even more devistating against Phantom Assassin.
* Primal Beast can dispel Stifling Dagger and any attack modifers it applies with his left level 15 talent.

* 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.

* Terrorblade has no stun and is vulnerable to Primal Beast's spell comboes due to his low health points in the laning stage and mid game.
* Reflection can be dispelled using Primal Beast's level 15 left talent.
* Sunder is the only real threat Terrorblade has against Primal Beast but he may die before he can even use it.

* Any hero who lanes very poorly will struggle with Primal Beast's potential snowball in the very early levels, like Keeper of the Light, Luna, Templar Assassin...

* Dispersion reduces damage based on a percentage, which is very minimal against large amounts of small instances of damage such as Trample. It reduces each tick by about 14 at the maximum level, which is very small.
* Desolate is never a threat to Primal Beast due to his large health pool and Uproar is still out-damaging the ability.
* Onslaught can allow Primal Beast to chase Spectre fleeing with Spectral Dagger, as both skills phase through trees and terrain.
* Primal Beast can also dispel Spectral Dagger's slow with his left level 15 talent, making it completely useless against him.
* Primal Beast excels at early aggression, pushing weak carries out of lane and farming areas he wants to control. Overall just not a pleasant matchup for Spectre.
* Should Primal Beast buy an Aghanim's Scepter he can also break both passive abilities.

* Any hero with low mobility and max healthsuch as Silencer, Crystal Maiden etc.

* Heroes who rely on burst damage with magical damage will struggle to kill Primal Beast: Spirit Breaker, Gyrocopter, Leshrac

* 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.

* Heroes with unorthodox escapes will struggle against Primal Beast, such as Nature's Prophet, Tinker, and Templar Assassin.
