* Flame Guard blocks Dark Willow's magical burst damage, and harms her if she tries to get close to attack with Bedlam.
* Sleight of Fist and Fire Remnant makes it hard for Dark Willow to fully disable Ember Spirit.

* None of Dark Willow's spells pierce Spell Immunity, making Blade Fury a good counter against her.
* Dark Willow is generally fragile, which results in Omnislash being devastating against her.
* However, if Shadow Realm is activated during Omnislash then the attack damage is negated (though Omnislash can still jump to other enemies).
Additional:
* Blade Fury dispels most of Dark Willow's abilities, allowing Juggernaut to pass through Bramble Maze and cancel out Cursed Crown before the stun occurs.

* Juggernaut is invulnerable while using Omnislash, meaning that neither Blade Mail or Power Cogs will save Clockwerk, this is especially common during the early laning phase.
* Blade Fury will also ignore any damage dealt by Battery Assault, as well as dealing heavy damage. As long as Juggernaut has mana to cast it, any engagement with Power Cogs will hurt Clockwerk a lot more than Juggernaut.

* Ember Spirit's Fire Remnant is an easy way to escape from Clockwerk's Power Cogs.
* Flame Guard blocks most of the magical damage Clockwerk does.

* Heroes with high mobility will be able to avoid Gyrocopter's area attacks: Storm Spirit, Morphling, Ember Spirit

* Blade Fury and Omnislash allows Juggernaut to avoid Gyrocopter's area attacks entirely.

* Blade Fury allows Juggernaut to simply move out of Kinetic Field and to dodge Glimpse.
* Healing Ward can keep heroes trapped in the Static Storm alive.
* Omnislash can be used to dodge Glimpse.

* Ember Spirit with Sleight of Fist and Activate Fire Remnant
* Heroes that can dodge Glimpse:
* Puck with Phase Shift

* Chaos Knight with Phantasm
* Naga Siren with Mirror Image
* Tusk with Snowball
* Juggernaut with Omnislash
* Brewmaster with Primal Split
* Lifestealer with Infest
* Phoenix with Supernova

* Crystal Maiden is extremely fragile and she's an easy target for him. She has no real disables that can lock Ember Spirit down, and all of her skill damage can be negated with Flame Guard. The damage from Searing Chains, Flame Guard, and Sleigh of Fist can easily take her down.

* Juggernaut and Lifestealer have abilities (Blade Fury and Rage respectively) that prevent Crystal Maiden from using her spells on them in the early game, before Black King Bar and other magical reduction is even an issue.

* Heroes with good mobility to avoid Jakiro's abilities and with good chase to punish Jakiro from pushing a tower: Bloodseeker, Ember Spirit, Juggernaut, Phantom Assassin, Weaver.

* Heroes with good mobility to avoid Jakiro's abilities and with good chase to punish Jakiro from pushing a tower: Bloodseeker, Ember Spirit, Juggernaut, Phantom Assassin, Weaver.

* Ember Spirit can close the distance between Sniper easily with his Activate Fire Remnant and further keep Sniper in place with Searing Chains.
* With the help of Aghanim's Scepter, Sniper cannot outrun Ember Spirit or chase him, even if Sniper builds mobility items.

* Sleight of Fist with Battle Fury deals a lot of damage to Nature's Prophet's team if they stand close to his Treants, as well as killing all of his Treants and getting lots of gold.
* Ember Spirit with Fire Remnant and Boots of Travel can teleport and defend tower whenever Nature's Prophet tries to push.
Additional:
* Ember Spirit can easily deal with Nature's Call by using his Flame Guard and with Battle Fury. He also has multiple ways of escaping Sprout. Additionally, Ember Spirit can break Sprout's trees with Activate Fire Remnant and interrupt Teleportation with Searing Chains.

* Wraithfire Blast is quite predictable, and players with good reflexes will disjoint it with Blade Fury.
* Omnislash with Diffusal Blade & Aghanim's Scepter can prevent Wraith King from reincarnating unless he picks the level 20 talent that removes the mana cost from Reincarnation.

* Blade Fury protects Juggernaut from all of Tiny's magic burst damage, as well as dealing magic damage that bypasses the armor from Grow.

* Blade Fury makes Juggernaut immune against all of Snapfire's spells and allows him to get closer.
* A well-timed Omnislash allows Juggernaut to dodge Snapfire's spells, and she has no way to deal with it.

* Ember's magic damage build is able to burst down Alchemist due to his low strength gain and Alchemist's normal item pick up.

* Searing Chains prevents usage of Timber Chain.
* Timbersaw is vulnerable to magical burst damage, which Ember Spirit provides with Fire Remnant and Flame Guard.
* Timbersaw's abilities deal pure damage, thus they cannot remove Flame Guard.

* Juggernaut's instant spell immunity from Blade Fury helps him dodge Invoker's combos. He can dispel the disables from Cold Snap and Deafening Blast and dodge the damage from Chaos Meteor, as well as walk through Ice Wall.
* Juggernaut's high DPS allows him to kill split pushing Forge Spirit(s) effortlessly, and his high armor prevents them from being a threat to him.
* However, Invoker can hit Juggernaut with Sun Strike through Blade Fury, making the Tornado > Sun Strike combo a threat if he does not dodge Tornado.
Additional:
* Blade Fury, similar to Rage, grants immunity to Invoker's spells and can dispel some debuffs as well.
* Omnislash renders Juggernaut invulnerable to Invoker's spells and can easily take Invoker down.

* Blade Fury's damage over time dispels Refraction almost instantly.
* Juggernaut's high armor allows him to survive for long enough to remove Refraction and threaten her with Omnislash as long as he or his team carries detection.
* Templar Assassin's short attack range makes it difficult for her to target a well-placed healing ward. She cannot splash onto it with Psi Blades.

* Flame Guard makes Dark Seer not deal any damage with his skills to Ember Spirit.

* Ember Spirit has much higher mobility in Fire Remnant than Void Spirit.
* Ember's Flame Guard is effective against Void Spirit's spells, as most of them deal magical damage.
* The root from Searing Chains prevents Void Spirit from using Dissimilate or Astral Step.

* Juggernaut's high attack speed lets him destroy a Supernova easily. He can even attack a Supernova during Blade Fury with his regular attacks.
* Blade Fury protects Juggernaut from all of Phoenix's spells (except Supernova, which pierces spell immunity).
* Blade Fury can also dispel the attack speed slow from Fire Spirits and the movement speed slow from Icarus Dive.
* Phoenix's Icarus Dive will not protect it from Omnislash unless it dives into creeps, and Phoenix's low armor makes for an easy kill.

* Because of her low range, Luna cannot easily destroy Healing Ward.
* Both Blade Fury and Omnislash are direct counters to Eclipse, offering Juggernaut spell immunity.

* Searing Chains can stop Charge of Darkness if timed correctly.
* Activate Fire Remnant can be used to escape an approaching Spirit Breaker, or lead Spirit Breaker into a bad situation.
* Activate Fire Remnant and Sleight of Fist allows Ember Spirit to dodge Charge of Darkness if timed correctly.

* A pre-placed Fire Remnant allows Ember Spirit to escape Upheaval.
* Flame Guard blocks Shadow Word's damage.
* Sleight of Fist allows Ember Spirit to attack from range, ignoring Upheaval, and Searing Chains lets him interrupt it.

* Blade Fury makes Juggernaut immune to Elder Titan's stun, so there is a high chance he wont get caught in your ultimate although Earth Splitter pierces spell immunity.

* None of Zeus's abilities can damage a Juggernaut in Blade Fury.
* Zeus's short attack range makes it difficult for him to target a well-placed healing ward. His frequent use of Arc Lightning will have almost no effect on allies being healed by Juggernaut.
* Zeus has no way to defend himself, even if Juggernaut cannot use Blade Fury. He can be easily taken out if cornered, sometimes even without Omnislash.
Additional:
* Blade Fury negates all magical damage from Zeus.
* Omnislash can easily take down Zeus. However, be aware that most players will get a Eul's Scepter of Divinity or a Ghost Scepter against Juggernaut.

* Juggernaut's Healing Ward can help save allied supports when Spectre attempts a Haunt kill.
* Juggernaut has a stronger push potential than Spectre, enabling him to end the game early before Spectre can come online.
* Spectre is often paired with two supports that are often weak against Juggernaut.
* Juggernaut also tends to build a Manta Style, which can prevent Desolate from taking effect.
* Juggernaut is invulnerable against Dispersion while using Omnislash

* Fire Remnant allows Ember Spirit to escape while Ruptured.

* Sleight of Fist keeps Ember Spirit invulnerable until he hits every unit in its area of effect allowing him to stall for large amounts of time against Broodmother and her large amounts of spiderlings, or potentially damaging them enough if equipped with an item to improve wave clearing such as Battle Fury or Maelstrom to prevent her pushes entirely.
* Flame Guard will damage any of Broodmother's spiders in an area, deterring her from attempting to kill him. It can also be used during Sleight of Fist to amplify damage done.
* Fire Remnant allows Ember Spirit an escape from Broodmother that is unaffected by her Incapacitating Bite.

* Heroes that build Diffusal Blade or can fit it well into their item build will also make Medusa much less tanky: Riki, Naga Siren, Terrorblade, Juggernaut, Spectre, Slark,Drow Ranger.

* Heroes that heavily depend on illusions or summons, (Naga Siren, Terrorblade, Phantom Lancer, Lycan,...) are vulnerable to Sleight of Fist and even more so if Ember Spirit has Battle Fury.

* Heroes with considerable mobility can easily escape from a rolling Pangolier: Anti-Mage, Queen of Pain, Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, moreover, if a player is familiar with how Rolling Thunder work, they can adjust their movement to avoid it entirely and of course outplay the Pangolier player.

* Heroes who can dodge Earth Spirit's abilities: Ember Spirit, Puck, Weaver

* Juggernaut's low mana pool means that Mana Break and Mana Void will deal little damage to him. His Blade Fury allows him to Block the damage from Mana Break

* Skywrath's pitiful defences also make him easy meat to heroes with high physical burst like Juggernaut or Phantom Assassin, the latter occasionally downing a support Skywrath in a single Stifling Dagger.

* Juggernaut with Blade Fury
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with Mirror Image
* Omniknight with Heavenly Grace
* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.

* 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.

* Illusion heroes like the aforementioned Phantom Lancer or Naga Siren, or heroes that tend to buy Manta Style, like Luna or Juggernaut, will give Slardar a hard time, as his damage is single-targeted.

* Heroes with spell immunity: Juggernaut, Pangolier, Huskar.

* Heroes with stronger lane presence that can threaten to kill him: Batrider, Juggernaut, Ursa, Monkey King, Razor.

* Juggernaut's Healing Ward keeps his team healthy even when pushing against Keeper of the Light's Illuminate.
* Blade Fury can dispel Blinding Light, as well as dodge an incoming Illuminate. Juggernaut can attack towers during Blade Fury, so he can dodge an Illuminate without having to stop pushing.
* Keeper of the Light has low health, low armor, and no natural defense against Omnislash.

* Sleight of Fist, allows Ember Spirit to destroy all of Phantom Lancer's illusions.
* Flame Guard also deals significant damage to illusions, and protects against Spirit Lance.
* Phantom Rush is unable to catch Ember Spirit when he teleports to his Fire Remnants.
Additional:
* Sleight of Fist is the natural counter to Phantom Lancer's army of illusions, especially when combined with Battle Fury.

* Disruption is not reliable enough to catch an Ember Spirit with a backup Fire Remnant.
* Sleight of Fist will make quick work of the spawned illusions.
* Ember Spirit usually builds Eul's Scepter of Divinity to dispel Shadow Poison and Soul Catcher and Linken's Sphere to block Disruption and Demonic Purge.
* The best you can do against an Ember Spirit is to dispel his Flame Guard with your Demonic Purge.

* Ember Spirit can deal devastating damage to illusion heroes like Terrorblade with Sleight of Fist. Terrorblade also has no way of preventing Ember Spirit from getting Activate Fire Remnant off. Additionally, Ember Spirit's ability to fight from long range as well as his wide skill set won't give many opportunities for Terrorblade to get Sunder off.
Additional:
* Ember Spirit can deal devastating damage to Terrorblade and his illusions with Sleight of Fist.
* Terrorblade has no disable to lock down Ember Spirit and prevent him from escaping with Fire Remnant. In addition, he doesn't like purchasing disabling items, which are the only solutions to deal with Ember Spirit.

* Blade Fury blocks the damage done by Death Pulse and Reaper's Scythe. Additionally, Ghost Shroud decreases Necrophos's magic resistance, making him take more damage from Blade Fury.

* 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.

* Blade Fury negates Kunkka's X Marks the Spot.
* Kunkka has no way to dodge Omnislash.
* Kunkka has no way to hit Healing Ward directly in battle, and it mitigates Ghostship and Tidebringer's damage.

* Juggernaut can attack Remote Mines and trigger Proximity Mines while in Blade Fury.

* Cleave heroes will clear her illusions. Such heroes include Sven, Magnus, Dragon Knight in Elder Dragon Form, Ember Spirit (via item), Phantom Assassin (via talent or item), etc.

* The high mobility provided by Fire Remnant makes it hard for Windranger to find a good position to land Shackleshot or a full duration of Focus Fire.
* Flame Guard deals considerable magical damage to Windranger.

* Blade Fury makes Juggernaut immune to the damage from Life Break and Burning Spears.
* It can be instantly activated the second Juggernaut sees Huskar flying towards him with Life Break, blocking all damage.
* Healing Ward effectively negates any damage-over-time from Burning Spears.
* Huskar has no defense against Omnislash and takes heavy damage due to his low armor.

* Blade Fury completely counters all of Nyx Assassin's abilities except Vendetta, and does not allow him to disengage with Spiked Carapace.
* Omnislash makes quick work of Nyx Assassin, and Spiked Carapace offers no protection at all.

* Any hero with teleport abilities (e.g. Ember Spirit, Storm Spirit) can easily break Static Link.

* Ember Spirit is evasive and can dodge close encounters with melee heroes like Chaos Knight. Ember Spirit can't be caught with the slow from Reality Rift, and Flame Guard and Sleight of Fist can bring Phantasm's illusions down quickly.

* In general, heroes with spell immunity abilities won't be caught inside by Pit of Malice: Juggernaut, Lifestealer.
