Oracle
[wiki] rating: 2.0 (winrate: 50% pickrate: 9%)Kunkka
[wiki] rating: 2.0 (winrate: 44% pickrate: 4%)Dark Seer
* 
X Marks the Spot prevents Dark Seer or his allies from escaping with Surge.
Ember Spirit
* Using X Marks the spot Kunkka can prevent Ember Spirit from escaping with Activate Fire Remnant, until he purchase 
Eul's Scepter of Divinity or 
Linken's Sphere.
Nyx Assassin
[wiki] rating: 1.6 (winrate: 54% pickrate: 14%)Ember Spirit
* With 
Vendetta, Nyx Assassin can move closely to Ember Spirit when he's farming with his Flame Guard and use 
Spiked Carapace with 
Impale to provide a reliable and long disable.
* 
Mana Burn is also good, as Ember Spirit relies on his limited mana pool for the early to midgame.
Additional:
* Spiked Carapace can be easily triggered by 
Flame Guard or 
Battle Fury, setting up a deadly Impale.
Dark Seer
* Deals damage over time: 
Venomancer, 
Huskar, 
Ember Spirit, 
Dark Seer, 
Sand King, 
Doom
* The nature of some abilities turn them into an easy target for a turnover from Spiked Carapace:
* Slow-moving projectiles: 
Skywrath Mage, 
Tinker, 
Necrophos
* Large area-of-effect with delay or require channeling: 
Enigma, 
Crystal Maiden, 
Invoker, 
Shadow Fiend, 
Pugna, 
Keeper of the Light
* Deals damage over time: Venomancer, Huskar, Ember Spirit, Dark Seer, Sand King, Doom
Queen of Pain
[wiki] rating: 1.2 (winrate: 48% pickrate: 9%)Dark Seer
* Dark Seer's only disable is Vacuum. Though he starts off with high armor and health, he'll eventually have a hard time dealing with high mobility heroes such as 
Weaver or 
Queen of Pain.
Ember Spirit
* Queen of Pain can be a good hero for dealing with Ember Spirit with 
Orchid Malevolence, her pure damage nuke in 
Sonic Wave and a slow in 
Shadow Strike. However, Queen of Pain can be punished by Ember Spirit, as his Searing Chains prevents her from getting 
Blink off.
Outworld Destroyer
[wiki] rating: 1.0 (winrate: 53% pickrate: 17%)Ember Spirit
* The pure damage provided by 
Arcane Orb is a great addition for killing Ember Spirit.
* 
Astral Imprisonment fully negates all magic damage of Flame Guard and Searing Chains and will temporarily save himself from Sleight of Fist's physical damage, and Ember Spirit is not a hero that can counter these skills.
Clinkz
[wiki] rating: 1.0 (winrate: 52% pickrate: 5%)Ember Spirit
* Ember Spirit's Flame Guard provides no protection against Clinkz's physical damage output.
* Ember Spirit's low armor and health make him easy to kill quickly if a teammate can hold him down.
* If Clinkz has farmed an item that can disable, he can sneak up to and hunt down Ember Spirit while he farms or split pushes alone.
Huskar
[wiki] rating: 1.0 (winrate: 51% pickrate: 3%)Ember Spirit
* Ember Spirit does minimal damage to Huskar until the very late game.
Omniknight
[wiki] rating: 1.0 (winrate: 51% pickrate: 1%)Ember Spirit
* The pure damage provided by 
Purification is a great addition for killing Ember Spirit, as well as a good way of saving teammates.
* 
Guardian Angel will temporarily save his allies from Sleight of Fist's physical damage, and Ember Spirit is not a hero that will get Orchid Malevolence to counter it.
Lion
[wiki] rating: 1.0 (winrate: 50% pickrate: 16%)Ember Spirit
* Lion possesses two strong disables in 
Earth Spike and 
Hex and heavy magic burst with 
Finger of Death which help lock him down and prevent him from escaping with Activate Fire Remnant. When getting his 
Blink Dagger Lion can punish Ember Spirit's overextension immediately, or initiate a fight on him with disables.
Additional:
* Ember lacks any protection against Lion's disables early in the game and often does not acquire any later, allowing Lion to Hex or Earth Spike him before he escapes through his 
Fire Remnant.
* Although Flame Guard can prevent magic damage, it does not stop Lion's disables, and Lion can usually break through it with Finger of Death.
Drow Ranger
[wiki] rating: 1.0 (winrate: 49% pickrate: 5%)Ember Spirit
* Ember Spirit greatly relies on his spells to engage in battle. Drow Ranger can simply silence him with Gust and make him useless for a few seconds, which Ember Spirit cannot afford during a teamfight.
Silencer
[wiki] rating: 1.0 (winrate: 48% pickrate: 7%)Ember Spirit
* 
Global Silence and 
Last Word can prevent Ember Spirit from casting Activate Fire Remnant to escape.
* 
Glaives of Wisdom also provide high pure damage that is not negated by Flame Guard.
* 
Arcane Curse is also a potent harassing tool in the laning stage as its cooldown is lower than Flame Guard's.
Techies
[wiki] rating: 1.0 (winrate: 48% pickrate: 7%)Ember Spirit
* Ember Spirit relies on his Fire Remnant to keep a steady push and then retreat to a safe distance. Keeping two or three patches of Remote Mines on a lane will severely impair him from pushing that lane without risking his life.
Anti-Mage
[wiki] rating: 1.0 (winrate: 47% pickrate: 14%)Dark Seer
* Dark Seer's strength lies in his high-mana cost skills. So 
Mana Break can be a great nuisance for him, since it can reduce his mana and prevent him from casting his spells.
* 
Mana Void can deal a lot of damage if Dark Seer spent a lot of mana on his abilities.
Shadow Fiend
[wiki] rating: 1.0 (winrate: 46% pickrate: 18%)Ember Spirit
* 
Shadowraze can easily remove the protection from Flame Guard and kill Ember Spirit due to his low health.
* Ember Spirit is very vulnerable to physical damage from 
Necromastery.
Faceless Void
[wiki] rating: 1.0 (winrate: 41% pickrate: 4%)Ember Spirit
* Faceless Void is one of the best heroes against Ember Spirit, providing a lot of ways of dealing with him. Ember Spirit becomes a lot weaker if affected by 
Time Dilation, as he can no longer spam Sleight of Fist.
* 
Chronosphere is also a reliable lockdown for Ember Spirit, although it can be evaded sometimes by Activate Fire Remnant. Additionally, Void can easily negate Sleight of Fist damage with 
Time Walk.
* And finally, Void is a great 
Diffusal Blade carrier. Not only 
Manabreak's physical damage not negated by Flame Guard, but it also burns Ember Spirit's mana. That, in turn, prevents him from escaping if he survived Chronosphere.
Beastmaster
[wiki] rating: 0.6 (winrate: 56% pickrate: 7%)Ember Spirit
* Heroes who rely on high mobility are especially vulnerable to Primal Roar: 
Storm Spirit, Ember Spirit, Queen of Pain.
Puck
[wiki] rating: 0.6 (winrate: 53% pickrate: 18%)Ember Spirit
* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, Storm Spirit, Ember Spirit, 
Lycan, 
Bloodseeker, 
Anti-Mage, 
Timbersaw
Underlord
[wiki] rating: 0.6 (winrate: 53% pickrate: 8%)Dark Seer
* In general, melee heroes without blink mechanisms or spell immunity will have a hard time positioning against Pit of Malice: 
Sven, 
Tiny, 
Wraith King, 
Dragon Knight, 
Meepo, Doom, 
Bounty Hunter, Dark Seer, 
Undying, 
Alchemist, 
Legion Commander.
Monkey King
[wiki] rating: 0.6 (winrate: 51% pickrate: 17%)Dark Seer
* In general, heroes who are melee with no way to fight back can be very easily poked by Monkey King to gain his Jingu Mastery stacks: Dark Seer, 
Riki, 
Rubick.
Weaver
[wiki] rating: 0.6 (winrate: 50% pickrate: 8%)Dark Seer
* A well-timed use of The Swarm provides vision over heroes with high mobility: Anti-Mage, 
Arc Warden, Dark Seer.
Doom
[wiki] rating: 0.6 (winrate: 46% pickrate: 3%)Ember Spirit
* The general opinion that Doom can counter Ember Spirit with his 
Doom is a misconception, as Doom has a long cast animation, so an attentive Ember Spirit can easily dodge it if he has a Fire Remnant nearby. Doom is still an extremely effective early ganker however, as his 
Scorched Earth and 
Infernal Blade damage can quickly overwhelm Flame Guard's magic damage absorption, leaving Ember Spirit with no protection against them. Additional skills that Doom can get from Neutral creeps can also help bully Ember Spirit early. 
Shadow Blade or Blink Dagger on Doom can also help, providing a good way to apply Doom on Ember Spirit.
Additional:
* Ember Spirit cannot use his 
Activate Fire Remnant while Doomed to escape from Doom.
Enchantress
[wiki] rating: 0.4 (winrate: 40% pickrate: 1%)Ember Spirit
* Impetus will deal huge amounts of damage when he uses a Fire Remnant to escape.
* Flame Guard is useless against Impetus.
* Enchant dispels Flame guard.
Dark Seer
* Heroes with haste can negate Enchant's slow: Weaver, Dark Seer, Lycan, 
Centaur Warrunner.
Terrorblade
[wiki] rating: -2.0 (winrate: 48% pickrate: 4%)Dark Seer
* Dark Seer's 
Vacuum and 
Ion Shell allows him to clear a wave of Terrorblade's illusions.
* 
Wall of Replica can create stronger illusions of Terrorblade.
* If Dark Seer can use Vacuum to help teammates land their AoE skills, Terrorblade will be quickly killed before he even gets a chance to use Sunder.
Additional:
* Dark Seer's Vacuum and Ion Shell allows him to clear the wave of Terrorblade's illusions.
* Wall of Replica can create stronger illusions of Terrorblade.
* If Dark Seer can use Vacuum to help teammates land their AoE skills, Terrorblade will be quickly killed before he even gets a chance to use 
Sunder.
Ember Spirit
* 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.
Warlock
[wiki] rating: -2.0 (winrate: 51% pickrate: 5%)Dark Seer
* 
Surge allows for Dark Seer and his allies to escape from 
Upheaval due to it ignoring any slow.
Ember Spirit
* 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.
Broodmother
[wiki] rating: -2.0 (winrate: 56% pickrate: 2%)Dark Seer
* Ion Shell zones out Broodmother in the laning phase, and can kill her spiderlings if used on one Spiderling in a group.
* Vacuum can pull Broodmother out of the treeline.
Additional:
* Ion Shell is a very powerful weapon against Broodmother's Spiderlings and makes her laning much harder.
Ember Spirit
* 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.
Chaos Knight
[wiki] rating: -1.6 (winrate: 49% pickrate: 3%)Ember Spirit
* 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.
Dark Seer
* Heroes that rely on illusions will suffer against Ion Shell, which kills them very quickly: 
Phantom Lancer, 
Chaos Knight, 
Naga Siren, Meepo.
* Heroes that rely on illusions typically spawn very strong illusions inside your Wall of Replica that you should use against them or their team.
Phantom Lancer
[wiki] rating: -1.6 (winrate: 50% pickrate: 9%)Dark Seer
* Heroes that rely on illusions will suffer against Ion Shell, which kills them very quickly: Phantom Lancer, Chaos Knight, Naga Siren, Meepo.
* Heroes that rely on illusions typically spawn very strong illusions inside your Wall of Replica that you should use against them or their team.
Ember Spirit
* 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.
Meepo
[wiki] rating: -1.4 (winrate: 46% pickrate: 1%)Ember Spirit
* Heroes with high mobility can be prevented from using it to their advantage with Earthbind, even if they pack a dangerous arsenal: 
Earth Spirit, Ember Spirit, Storm Spirit, 
Nature's Prophet, 
Phantom Assassin, Riki, Anti-Mage, Weaver.
* See items and abilities disabled by roots
Dark Seer
* Dark Seer can take great advantage of 
Divided We Stand by putting an Ion Shell on a clone in order to harass them effectively.
* Vacuum can take a single Meepo and disable them for him and his teammates to take out.
Ember Spirit
* Meepo is quite fragile in the early game and can be easily taken down by Flame Guard's and Searing Chains' damage. Later on, Meepo is very vulnerable to Sleight of Fist's damage due to Battle Fury's cleave on multiple Meepos.
Additional:
* Sleight of Fist boosted by Battle Fury and 
Daedalus makes quick work of Meepo if clones are crowded around each other.
* Searing Chains interrupts Meepo's initiating because Meepo's clones do not have spell immunity.
Pangolier
[wiki] rating: -1.2 (winrate: 49% pickrate: 9%)Ember Spirit
* 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.
Dark Seer
* Certain heroes can mess up with Pangolier's positioning and timing (especially if he intends to use Rolling Thunder during combat): 
Vengeful Spirit, Keeper of the Light, Huskar, Dark Seer
Naga Siren
[wiki] rating: -1.2 (winrate: 51% pickrate: 2%)Ember Spirit
* 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.

Razor
[wiki] rating: -1.2 (winrate: 55% pickrate: 4%)Dark Seer
* Dark Seer can increase the movement speed of allies with Surge, breaking Static Link.
Ember Spirit
* Any hero with teleport abilities (e.g. Ember Spirit, Storm Spirit) can easily break Static Link.
Nature's Prophet
[wiki] rating: -1.0 (winrate: 45% pickrate: 7%)Ember Spirit
* 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

Crystal Maiden
[wiki] rating: -1.0 (winrate: 50% pickrate: 14%)Ember Spirit
* 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.
Windranger
[wiki] rating: -1.0 (winrate: 50% pickrate: 16%)Ember Spirit
* 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.
Venomancer
[wiki] rating: -1.0 (winrate: 50% pickrate: 5%)Dark Seer
* Venomancer is a low health hero and low range distance attack hero easily to harass putting Ion Shell in a distance creep enemy in early game .
* Venomancer depends entirely on all his slows poison skills to keep distance or chasing enemy heroes, but Surge ignores slows, so is nearly impossible hunt or run away of Dark Seer or his surged teammates.

Void Spirit
[wiki] rating: -1.0 (winrate: 51% pickrate: 12%)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.
Treant Protector
[wiki] rating: -1.0 (winrate: 51% pickrate: 5%)Dark Seer
* 
Living Armor can be destroyed quickly with Ion Shell.
Alchemist
[wiki] rating: -1.0 (winrate: 53% pickrate: 7%)Ember Spirit

Additional:
* Fire Remnant allows Ember Spirit to escape while Ruptured.
Slark
[wiki] rating: 0.0 (winrate: 47% pickrate: 13%)Dark Seer
* Dark Seer relies on Surge for most of his mobility, so he's not very vulnerable to slows, but much more to root effects and walls or pseudo-walls such as 
Disruptor's 
Kinetic Field or Slark's 
Pounce.
Dark Seer
* Heroes with AoE abilities will hit Slark in Shadow Dance: 
Lina, 
Jakiro, 
Underlord, 
Leshrac, Dark Seer, 
Earthshaker, Timbersaw, Crystal Maiden
Shadow Demon
[wiki] rating: 0.0 (winrate: 48% pickrate: 2%)Dark Seer
* The constant dispel from Demonic Purge will make any attempt to save the victim or himself by Surge become futile. For what it's worth, Demonic Purge will also dispel Ion Shell.
Ember Spirit
* Disruption is not reliable enough to catch an Ember Spirit with a backup Fire Remnant.
* Sleight of Fist will also make quick work of the spawned illusions.
* Ember Spirit usually builds Eul's Scepter of Divinity to dispel 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.
Sniper
[wiki] rating: 0.0 (winrate: 48% pickrate: 6%)Dark Seer
* A Sniper who is somewhat competent at positioning is hardly going to be affected by any of Dark Seer's spells thanks to 
Take Aim.

Ember Spirit
* 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.
Storm Spirit
[wiki] rating: 0.0 (winrate: 48% pickrate: 11%)Ember Spirit
* Storm Spirit is not only a potent Orchid Malevolence carrier, his 
Electric Vortex provides an additional disable and 
Overload provides a great slow. When paired with 
Static Remnant, they can cut through Flame Guard fast.
* 
Ball Lightning not only provides great initiation upon Ember Spirit from any position anytime, but also helps dodge Sleight of Fist.
Ember Spirit
* Flame Guard absorbs up to 500 magical damage (700 with Level 10 talents), which helps Ember Spirit survive and react to Storm Spirit's high magical damage.

* Fire Remnant deals high magical damage when casting multiple instances at once, granting Ember Spirit the damage to burst Storm Spirit down in the early to mid game.
Disruptor
[wiki] rating: 0.0 (winrate: 49% pickrate: 9%)Dark Seer

* Fortune's End can dispel
Ion Shell, which cripples Dark Seer economy since it's his most efficient tool for farming.
Surge, effectively slowing his movement speed making him vulnerable to ganks or skirmishes.
Fortune's End dispels Ion Shell and Surge, making any gank attempt on Dark Seer in the laning phase likely to succeed.
Fate's Edict prevents all magical damage that comes from Dark Seer's abilities. 
Fortune's End dispels Ion Shell on creeps, which Dark Seer relies on to farm and zone.
* Fortune's End can dispel
Additional:

Ember Spirit
* Oracle can shut down both of Ember's early game abilities. Fortune's End can dispel
Flame Guard on Ember Spirit and 
Searing Chains on allies.
Fire Remnants move at 0 movement speed.
Sleight of Fist ability, possibly making him useless for a few seconds in the late game without a dispel or spell immunity. This is especially good if he has a rapier or two. However, positioning for this is difficult when Ember plays far back.
* When Ember Spirit is affected by Fortune's End, his
* Disarming him with Fate's Edict does affect Ember's
