Vendetta disables Vengeance Aura and allows him to attack Vengeful Spirit with 
Impale and 
Mind Flare.
* 
Spiked Carapace is easy to use against a Wave of Terror or Magic Missile.
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.
Vengeful Spirit
* 
Ball Lightning disjoints an incoming 
Magic Missile, avoids 
Wave Of Terror, and allows Storm Spirit to easily escape if he ever gets 
Nether Swapped.
Dark Willow
* Ball Lightning allows Storm Spirit to bypass Bramble Maze into the backline, and zip back into battle if he gets hit by Terrorize.
Vengeful Spirit
* Strong nuking supports like 
Skywrath Mage. Vengeful Spirit has subpar attack range, making it harder for her to harass and last hit safely. With enough pressure she can be bullied out of a lane.
Additional:
* Skywrath Mage should have the upper hand against Vengeful Spirit with Ancient Seal.
* Vengeful is highly dependant on her abilities and has no natural means to deal against silences.
* Her low attack range allows Skywrath Mage to easily bully her out of the lane.

* 
Spark Wraith also exploits Dark Willow's low mobility.
Dark Willow
* 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.
Additional:
* 
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.
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.

* 
Phantom Rush with his illusions can chase Vengeful Spirit efficiently.

* Viper can easily bully Vengeful Spirit out of a lane with 
Poison Attack.
Additional:
* Nethertoxin prevents the attack damage bonus from 
Vengeance Aura and the components of Nether Swap.
* Both Magic Missile and Wave of Terror are counteracted by 
Corrosive Skin, making Vengeful Spirit's fighting harder against Viper.
Dark Willow
* 
Quill Spray's constant AoE damage will hit Dark Willow even in Shadow Realm. Its automatic damage will hurt her if she tries to get close and use Bedlam.
Dark Willow
* 
Berserker's Call forces Dark Willow to attack, cancelling Shadow Realm.
Dark Willow
* 
Rot and 
Meat Hook hits Dark Willow even when she uses Shadow Realm.

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.
Vengeful Spirit
* Vengeful Spirit should carefully consider whether to use her Nether Swap on Tidehunter, as it can easily position him for a 
Ravage on Vengeful Spirit and her allies.
* Due to Magic Missile's high damage, 
Kraken Shell will often proc and clear Tidehunter's debuffs.
Vengeful Spirit
* All of Vengeful Spirit abilities are very good for Rubick to 
Spell Steal:
* Magic Missile provides an additional nuke/disable to pair with 
Fade Bolt and 
Telekinesis, respectively.
* Wave of Terror serves as a good scouting/armor reduction skill that Rubick and his team can benefit from.
* Nether Swap complements Rubick's mobility and pairs well with other mobility items he usually builds. He can also use it to save an ally from danger.
Additional:
* Magic Missile is a solid damage source and lockdown that fits nicely with Rubick's kit.
* Rubick also acquires the secondary Magic Missile with 
Aghanim's Shard.
* Wave of Terror can be used to scout an area to prevent juking or initiate with Telekinesis, as well as reducing the armor of enemy team during a teamfight.
* Nether Swap does what it does - saving an ally from danger, initiating on an enemy, or helping with caughting a fleeing hero.
* With Aghanim's Shard, Rubick can lift himself up and drop quickly to a place of safety after the swap. Note that Rubick can only choose to either disable the enemy or save himself at one time with Telekinesis.
Dark Willow
* 
Flame Guard blocks Dark Willow's magical burst damage, and harms her if she tries to get close to attack with Bedlam.

Vengeful Spirit
* With the exception of Magic Missile (unless the player takes the Level 25 Talent "Magic Missile Pierces Spell Immunity"), all of Vengeful Spirit's spells ignore Spell Immunity. This also makes her good against heroes with built-in Spell Immunity like 
Lifestealer or 
Juggernaut or heroes that tend to pick up Black King Bar, like Sven.
Dark Willow
* Rage protects Lifestealer from all of Dark Willow's abilities.
Additional:
*

Light Strike Array before Vengeful Spirit lands her Magic Missile.
* 
Laguna Blade deals massive damage, often being enough to kill a squishy Vengeful Spirit.
Vengeful Spirit
* Heroes with abilities that can pull Lina out of position can easily bring her to their team mates, like 
Batrider with 
Flaming Lasso, 
Pudge with Meat Hook and Vengeful Spirit with Nether Swap.
Dark Willow
* 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).
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.
* However, Dark Willow can tank Omnislash with Shadow Realm. As she is a valid target, but invulnerable to right clicks.
Vengeful Spirit
* With the exception of Magic Missile (unless the player takes the Level 25 Talent "Magic Missile Pierces Spell Immunity"), all of Vengeful Spirit's spells ignore Spell Immunity.

Vengeful Spirit
* With Nether Swap, Vengeful Spirit can isolate one of the Meepos, making him an easier kill for the team.

Poof, preventing isolated Meepos from fleeing.
Dark Willow
* Heroes who can stun multiple units at once: Dark Willow, 
Spirit Breaker, 
Slardar, 
Invoker, and 
Tidehunter.
Additional:
* 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.
Vengeful Spirit
* 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
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
Vengeful Spirit
* With her Nether Swap, Vengeful Spirit can save the life of an ally who gets caught with Flaming Lasso. Nether Swap also makes it highly dangerous for Batrider to attempt a lasso, as it can lead to his own demise far behind enemy lines.

Dark Willow
* Terrorize, Bedlam and Cursed Crown can damage Muerta through Pierce the Veil.

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.

Vengeful Spirit
* Vengeful Spirit has two abilities to interrupt Death Ward, even through Black King Bar.
Vengeful Spirit

Disruptor, Pudge, Vengeful Spirit.

Vengeful Spirit
* Past the mid game, an isolated Vengeful Spirit makes for an easy kill for Anti-Mage.

Counterspell.
* Magic Missile is the only disable Vengeful Spirit has against Anti-Mage, but he can either
* Nether Swap isn't very effective against Anti-Mage - if used offensively, Anti-Mage can simply blink away to safety, and if used defensively, Blink's low cooldown allows him to persistently chase as well.
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
