Warlock
* 
Impale and 
Spiked Carapace interrupts Upheaval with ease.
* Warlock's low health pool, mobility, and high intelligence gain makes him a prime target for Nyx Assassin's burst damage.
Dark Willow
* Nyx Assassin's high burst damage can be the bane of Dark Willow, as her low health makes it difficult to survive long enough to escape through Shadow Realm.
* Spiked Carapace can be triggered by walking deliberately into Bramble Maze, leaving Dark Willow stunned and defenseless.
Warlock
* Because Warlock's abilities are all active abilities, Silencer can make his impact minimal.
* 
Arcane Curse prevents Warlock from using his abilities without increasing it's duration, which since all of Warlock's abilities are actives it is very effective against him.
* 
Last Word can prevent Warlock from casting his Fatal Bonds, Chaotic Offering, and Upheaval combo.
* 
Global Silence can nullify Warlock's impact in fights by preventing him from casting Fatal Bonds and Chaotic Offering, or by interrupting his Upheaval.

* 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.
Warlock

Crystal Maiden, 
Dawnbreaker, 
Enigma, 
Pudge, 
Shadow Fiend, 
Shadow Shaman, 
Warlock.
Dark Willow
* Jakiro's area of effect abilities can hit Dark Willow even while she is hidden during the 
Shadow Realm.
* Waiting about 2 seconds after Dark Willow casts Shadow Realm to cast Ice Path will stun her while her Shadow Realm is at it's maximum damage.
* Jakiro can stun Dark Willow when there is about 1 second left on 
Cursed Crown, Jakiro's Ice Path stun lasts slightly longer then Cursed Crown.
Warlock
* Warlock is a very strong hero when positioned correctly, and his long cast range helps him with this. However, some Heroes might disrupt or sneakily pass through his allies and deal with him, preventing him from doing his job. Such heroes include 
Chaos Knight, 
Spirit Breaker, 
Riki, and more.
Dark Willow
* 
Smoke Screen prevents Dark Willow from using her abilities, rendering her defenseless and unable to deal any serious damage.
* 
Blink Strike lets Riki jump past Bramble Maze.
Warlock
* Because all of Warlock's abilities are active abilities, silences can make his impact in fights minimal. Be cautious of heroes that carry silences like 
Death Prophet, 
Puck, and the aforementioned 
Silencer.
Dark Willow
* All of Puck's abilities are area-targeted, and will hit Dark Willow when she uses Shadow Realm.
* 
Illusory Orb allows Puck to bypass Bramble Maze, close the gap and silence Dark Willow with 
Waning Rift.
* 
Phase Shift helps Puck dodge attacks charged by Shadow Realm, and is easily timed against Terrorize's long cast time.
Warlock
* With God's Strength, Warlock Golem goes down in a matter of seconds. The two weaker golems granted by 
Aghanim's Scepter will fare worse due to Great Cleave hitting both.

Shadow Word.
Additional:
* 
God's Strength combined with 
Great Cleave destroys Chaotic Offering golems within seconds.

* 
Storm Hammer disrupts Upheaval.
Dark Willow
* Heroes with high burst damage and 
Black King Bar can take down Dark Willow quickly: 
Phantom Assassin, 
Sven, 
Wraith King
Warlock
* Because all of Warlock's abilities are active abilities, silences can make his impact in fights minimal. Be cautious of heroes that carry silences like Death Prophet, Puck, and the aforementioned Silencer.
Dark Willow
* Heroes who can silence will shut down Dark Willow entirely: Death Prophet, Silencer, 
Drow Ranger
Dark Willow
* 
Magnetic Field lets Arc Warden or allies evade Dark Willow's shadow realm attacks. The duration of the evasion can be extended with the clone.
* 
Spark Wraith also exploits Dark Willow's low mobility.
Warlock
* Ghostship helps your team soak up damage from 
Chaotic Offering and hit summons hard.
* Tidebringer clears summons later in the game.
* Most of your spells can interrupt 
Upheaval.
Dark Willow
* 
Fortune's End not being disjointable is almost an ensured disable if Dark Willow tries to escape with Shadow Realm. Dispels Cursed Crown and Terrorize.
* 
Fate's Edict negates all her magic damage in case she catches a single hero.
* 
False Promise's strong dispel removes Dark Willow's disables.
Additional:
* Fortune's End can easily dispel Cursed Crown before it times out and stuns. He can also save a stunned ally with False Promise.
* Fate's Edict can easily negate 
Bedlam's over-time damage, since the spell provides no form of control. Similarly, he can also negate the magic burst from Shadow Realm.
* Fortune's End can dispel the fear effect from 
Terrorize, and it can remove the root from 
Bramble Maze if cast quick enough. Be mindful that Fortune's End only dispels your allies' debuffs on the primary target.
Warlock
* 
Shapeshift allows Lycan to escape from Upheaval with maximum movement speed.
* Warlock doesn't have a good solution to deal with Lycan's wolves from 
Summon Wolves.
Warlock
* 
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.

Dark Willow
*

Dark Willow
*

Octarine Core make cooldown reduction abilities from Rubick and addition instanly Warlock's Golem from Chaotic Offering stollen.
* Telekinesis from Rubick can help stopped from Upheaval chancelled. Telekinesis also stopped from Upheaval with throw creeps and enemy hero touch down to Warlock. Rubick's can build 
Aghanim's Shard save the his allies trapped from Upheaval.

* Fatal Bonds makes Rubick simplify fighting from target.
Additional:
* All abilities from Warlock is very vulnearble stealing by Rubick with 
Spell Steal primarily Chaotic Offering.
* Rubick always purchase Aghanim's Scepter will additionally Rubick's instanly Chaotic Offering stolen although Warlock's without purchase Aghanim's Scepter.
* 
Telekinesis can cancelled Upheaval lift up Warlock's and also can cancel from Upheaval with nearby creeps and enemy hero from Telekinesis can throw and touch down to Warlock's. Additionally, Telekinesis can save allies from Upheaval trap will upgrade with Aghanim's Shard.
Dark Willow
* Heroes with high burst damage and Black King Bar can take down Dark Willow quickly: Phantom Assassin, Sven, Wraith King
Warlock
* Warlock is a very strong hero when positioned correctly, and his long cast range helps him with this. However, some Heroes might disrupt or sneakily pass through his allies and deal with him, preventing him from doing his job. Such heroes include Chaos Knight, Spirit Breaker, Riki, and more.
Warlock
* Heroes that have small health pools and little to no escape mechanisms are even easier prey for Necrophos. Ghost Shroud's slow will allow him to catch him with them, and get nuked down with his abilities, even preventing retaliation due to Reaper's Scythe's stun. Such heroes include Crystal Maiden, 
Witch Doctor, Warlock or Shadow Fiend.
Warlock
* Heroes that rely on summons will suffer against Ion Shell, which kills them very quickly: 
Beastmaster, 
Broodmother, Enigma, 
Nature's Prophet, 
Visage, Warlock, Wraith King.
Additional:
* 
Surge allows for Dark Seer and his allies to escape from Upheaval due to it ignoring any slow.
Warlock
* 
Ursa can shred Warlock's Golems in a few seconds with 
Fury Swipes and 
Overpower.
Warlock
* Heroes who rely on summons will see them destroyed easily by Overwhelming Odds: 
Lycan, 
Arc Warden, Warlock, 
Chen
Warlock
* Supports with useful teamfight or contribution spells will be helpless against Doom: 
Dazzle, 
Oracle, Warlock.
Dark Willow
* 
Rage protects and dispels all of Dark Willow's abilities.
Additional:
* Rage protects Lifestealer from all of Dark Willow's abilities.
Warlock
* Heroes with summons: Lycan, Broodmother, Visage, Nature's Prophet, Warlock.
Dark Willow
* 
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.
* However, Dark Willow can tank 
Omnislash with Shadow Realm. As she is a valid target, but invulnerable to right clicks.
Additional:
* None of Dark Willow's spells pierce Spell Immunity, making Blade Fury a good counter against her. Additionally, it dispels Cursed Crown and Bramble Maze.
* 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).
Warlock
* Chaotic Offering can stop heroes who like to use spell immunity and teleport scrolls to safely farm during the early to mid game, since it stuns and also goes through spell immunity. Notable examples: 
Juggernaut, 
Lifestealer.
Dark Willow
* 
Gust can hit Dark Willow beyond a defensive Bramble Maze, and before she gets close enough to hit Drow Ranger with Bedlam.
* Drow Ranger's long range allows her to hit Dark Willow's team without venturing into her Bramble Maze.
Warlock
* While heroes with strong mobility are able to get close or flee from Upheaval, heroes with no escaping abilities or that lack long disables will perish against Warlock. Once the Warlock Golem lands with its stun, its hardly possible to escape when he casts Upheaval. Notable examples: 
Huskar, Drow Ranger, 
Lion, 
Elder Titan, etc.
Warlock
* Warlock has strong counter initiation which reduces Marci's effectiveness throughout the game.
* Fatal Bonds cancels 
Blink Dagger, which means Marci can move in and out of fights less effectively.
* Chaotic Offering paired with Upheaval provides a ministun, a movement slow and paired with Fatal Bonds has the potential to deal a lot of damage to Marci while she jumps on a target. The ministun also means that Marci will have a harder time casting Rebound. If Warlock does build Aghanim's Scepter and 
Refresher Orb, the physical damage from Golems will overwhelm Marci, especially when played as a support.
Dark Willow
* Bramble Maze will very likely catch Marci midair, disabling Marci's chasing/fleeing ability.
* Shadow Realm prevents Marci from bursting Willow down since she relies on physical attacks and unit target spells. With Aghanim's Scepter, Willow can hit Marci while Marci can't hit Willow.
* Bedlam and 
Eul's Scepter of Divinity allows Willow to manfight if Marci initiates with Rebound.
* Terrorize and Cursed Crown combo can waste Marci's ultimate for almost half of its duration.
Warlock
* Fatal Bonds links the Meepos together, which combined with area of effect damage or Cleave will be devastating.
Dark Willow
* Casting Bramble Maze on top of Meepo guarantees a root, as it is nearly impossible to leave the thorns with all of Meepo's clones.
* Terrorize and Cursed Crown offer great disables against the grouped Meepos and can prevent them from using 
Poof to escape.
Dark Willow
* Bramble Maze prevents Timbersaw from 
Timber Chaining away without getting rooted.
* Cursed Crown can still catch Timbersaw if he Timber Chains away.
* 
Reactive Armor offers little protection against Dark Willow's high magical damage.
Warlock
* Chaotic Offering's spell immunity piercing stun can stop Black Hole's channeling. Due to this ability's large area of effect, it can be cast at a safe distance from the Black Hole. It also goes through Black King Bar and ignores 
Linken's Sphere.
* Fatal Bonds and Aghanim's Shard upgraded Shadow Word can be used to make Enigma's Eidolons easier to kill, potentially feeding the enemy team. Also,their constant damage will put Blink Dagger on cooldown, potentially forcing Enigma to prematurely activate Black King Bar.
Additional:
* Chaotic Offering pierces spell immunity and is an area of effect ability, therefore it doesn't matter if Enigma buys Black King Bar or Linken's Sphere, Warlock will always be able to cancel the channeling of 
Black Hole.
* Enemies often get clumped up around Black Hole to hit your allies, giving you a perfect opportunity to cast Fatal Bonds, Chaotic Offering, and Upheaval on multiple enemies.
Dark Willow
* Terrorize forces Monkey King out of 
Wukong's Command.
Dark Willow
* 
Windrun does not protect Windranger from Cursed Crown's stun or Dark Willow's magical nukes.
* 
Focus Fire cannot target Dark Willow in Shadow Realm and will be interrupted if targeted earlier, wasting the ultimate.
Additional:
* Windrun does not protect Windranger from Cursed Crown stun or Dark Willow's magical nukes.
* Focus Fire cannot target Dark Willow in Shadow Realm and will be interrupted if targeted earlier, wasting the ultimate.
Warlock
* Chaotic Offering's vast area-effect can destroy trees and stun Hoodwink.
* Upheaval makes retreating with 
Scurry difficult.
Dark Willow
* Bramble Maze greatly hinders Bloodseeker's ability to run around in teamfights and pick off dying allies.
* Shadow Realm prevents Bloodseeker from attacking dark Willow, allowing her to safely teleport away.
Dark Willow
* Terrorize, Bedlam and Cursed Crown can damage Muerta through Pierce the Veil.
* Shadow Realm can be used to escape Pierce the Veil's high damage, as Muerta cannot attack her while she is in it.
Dark Willow
* Terrorize forces Faceless Void out of 
Chronosphere.
Warlock
* Warlock is a very strong hero when positioned correctly, and his long cast range helps him with this. However, some Heroes might disrupt or sneakily pass through his allies and deal with him, preventing him from doing his job. Such heroes include Chaos Knight, Spirit Breaker, Riki, and more.
Warlock
* Heroes with summons and illusions as Spirit Breaker has no strong AoE capabilities to deal with them: Chaos Knight, 
Phantom Lancer, 
Terrorblade, 
Naga Siren, Broodmother, Warlock, Visage, Nature's Prophet, Shadow Shaman, Lycan.
Dark Willow
* Bramble Maze stops 
Charge of Darkness in its tracks. Its very long duration means it can be used as an obstacle to block off an incoming Spirit Break during teamfights.
* Shadow Realm and Bedlam can be activated when Dark Willow sees Charge of Darkness coming, preventing Spirit Breaker from using 
Nether Strike after the initial stun.
Dark Willow
* Dark Willow's burst damage and stun prevents Troll Warlord from approaching her until he has Black King Bar.
* Troll Warlord's lack of burst damage makes it hard for him to kill Dark Willow before she slips into Shadow Realm.
Warlock
* Warlock Golems do plenty of physical and pure damage to bring down Huskar when he is at low health. Warlock is always a hazard for Huskar to initiate by using 
Life Break, because Chaotic Offering can stun him instantly, even when Black King Bar is activated, and allows Warlock's team to gather their wit and retaliate.
* After using Life Break to jump in, Huskar will not have any means to escape Upheaval. Which since he is an attack-dependent hero, this will nullify his impact in fights.
Dark Willow
* Heroes with high magical or pure damage will bypass Bulwark: 
Timbersaw, 
Dark Willow, Enigma, 
Invoker, 
Pugna, 
Skywrath Mage, 
Tinker, 
Zeus, Oracle.
Dark Willow
* Heroes with powerful rooting abilities will disable most of Pangolier's skills, a bonus point if it pierces spell immunity since it will also be able to stop Pangolier during his Rolling Thunder: 
Treant Protector, 
Meepo, Crystal Maiden, Dark Willow, 
Underlord, Naga Siren
Warlock
* While heroes with strong mobility are able to get close or flee from Upheaval, heroes with no escaping abilities or that lack long disables will perish against Warlock. Once the Warlock Golem lands with its stun, its hardly possible to escape when he casts Upheaval. Notable examples: Huskar, Drow Ranger, Lion, Elder Titan, etc.
Warlock
* Channeling heroes will not go well against Warlock, especially those who build Black King Bar as Warlock's ultimate ability stun goes through spell immunity. E.g.: Crystal Maiden, Witch Doctor, Enigma, etc.
Warlock
* Heroes with channeling spells because Shadow Fiend has nothing to cancel channeling outside of Requiem of Souls: 
Bane, Enigma, Pudge, Shadow Shaman, Dawnbreaker, Warlock, Crystal Maiden.
Additional:
* Because Shadow Fiend lacks escaping mechanisms, and is dependent on fair positioning for channeling 
Requiem of Souls, it's easier for Warlock with his long range crowd control abilities to lock Shadow Fiend down for his team.
Warlock
* Viper cannot interrupt heroes with powerful channeling abilities: Bane, Enigma, Shadow Shaman, Warlock
Dark Willow
* Primal Beast really suffers against supports he cannot bully in the lane: this includes Dazzle, 
Shadow Demon and Dark Willow since they can use their respective abilities to stop Primal Beast from dealing burst damage, or make it hard for him to stay in range.
Warlock
* Warlock often stays back and counter-initiates by dropping his Chaotic Offering on Earthshaker and his allies.
Warlock
* Heroes with illusions and summons can swarm Bane, who has no area abilities outside from Aghanim's Shard upgraded 
Brain Sap: Broodmother, Chaos Knight, Naga Siren, Nature's Prophet, Phantom Lancer, Terrorblade, Visage, Warlock, Wraith King.
Warlock
* Channeling heroes will not go well against Warlock, especially those who build Black King Bar as Warlock's ultimate ability stun goes through spell immunity. E.g.: Crystal Maiden, Witch Doctor, Enigma, etc.
Warlock
* Heroes with both illusions and summons, for Io has nothing to deal with multiple enemies at once outside from Spirits's weak area-of-effect: Beastmaster, Broodmother, Chaos Knight, Lycan, Naga Siren, Nature's Prophet, Phantom Lancer, Shadow Shaman, Terrorblade, Visage, Warlock, Wraith King.
Warlock
* While heroes with strong mobility are able to get close or flee from Upheaval, heroes with no escaping abilities or that lack long disables will perish against Warlock. Once the Warlock Golem lands with its stun, its hardly possible to escape when he casts Upheaval. Notable examples: Huskar, Drow Ranger, Lion, Elder Titan, etc.
Warlock
* Illusion and heroes with summons are difficult to kill with Chen's single-target offensive spells: Terrorblade, Phantom Lancer, Chaos Knight, Broodmother, Naga Siren, Lycan, Visage, Beastmaster, Warlock, Wraith King. And even though Chen can convert enemy summons with Holy Persuasion, their much greater numbers will often overwhelm Chen and his creeps.
Dark Willow
* Heroes with high burst damage and Black King Bar can take down Dark Willow quickly: Phantom Assassin, Sven, Wraith King
Warlock
* Heroes with illusions and summons can be hard for Phantom Assassin to deal with, as she lacks any AoE abilities to deal with them without items: Broodmother, Phantom Lancer, Chaos Knight, Lycan, Naga Siren, Shadow Shaman, Visage, Nature's Prophet, Terrorblade, Warlock, Wraith King.
Warlock
* 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
Warlock
* Because Templar Assassin does not have escape potential in lane, any support hero with roaming potential and a 
Dust of Appearance can be great at shutting her down early game: 
Earth Spirit, Spirit Breaker, 
Tusk, 
Bounty Hunter, Riki, Warlock.
Additional:
* Warlock can cast Upheaval when Templar Assassin uses 
Meld, preventing her from escaping at the right moment.
* Warlock can also send his Warlock Golem near where she used Meld, preventing escape by Blink Dagger due to the Warlock Golem's 
Permanent Immolation.
* Warlock's Golem's Permanent Immolation will burn away 
Refraction with its damage over time.
Warlock
*
Mana Break prevents Warlock from casting his spells, particularly in the laning phase.
Blink allows Anti-Mage to escape from Upheaval.
Counterspell reduces damage from Shadow Word and Warlock's Golem's 
Permanent Immolation passive. Additionally, it can reflect Shadow Word and Fatal Bonds.
Mana Void deals heavy damage after Anti-Mage has drained Warlock's large mana pool.
*
*
*
Dark Willow
*
Counterspell negates Dark Willow's high magic burst damage. Its active blocks 
Cursed Crown.
Blink allows Anti-Mage to dodge Terrorize during its long cast animation, as well as avoiding the obstacles from Bramble Maze. On the other hand, if Anti-Mage gets caught inside Bramble Maze, he's unable to Blink away.
Mana Voids.
*
* Dark Willow's chained magic burst requires a lot of mana, setting her up for damaging
