Lina
* 
Dragon Slave is easy to steal, and provides Rubick with a useful nuke.
* 
Light Strike Array serves as a cheap nuke as well as a crowd control ability.
* Rubick uses the fixed 0.15 second cast time when casting Light Strike Array, much faster than 
Lina herself.
* Rubick can gurantee a stun by throwing the victim into the area with 
Telekinesis, extending the overall lockdown duration.
* 
Laguna Blade is an awesome ultimate that gives huge burst damage.
* 
Arcane Supremacy (combined with Level 25 talent +40% Spell Amp For Stolen Spells, as of 7.31c) increases its damage before reduction to a whopping 660/882/1134(830/1162/1494) (and even more so with 
Aghanim's Scepter), without considering spell amplification from items.
* Laguna Blade is an intelligence hero with no regen ability, and casting Laguna Blade back to Lina can result in her unexpected sudden death, or severly hinder her presence in the rest of teamfight. Nevertheless, the skill can also be cast on other squishy heroes or help bursting down enemy carries.
* Light Strike Array and Laguna Blade has a short cast range, and Rubick can extend its range thanks to Arcane Supremacy.
Brewmaster
* Heroes with strong team-fight abilities (especially ultimates) like 
Tidehunter, 
Brewmaster, 
Death Prophet, etc.
Lina
* 
Arcane Curse makes it too difficult Lina from using her abilities, preventing her from building up Fiery Soul stacks without causing harm to herself.
* 
Last Word and 
Global Silence are great against Lina for the same reason, as well as interrupting her combos and preventing her from casting spells.
Brewmaster
* Outworld Destroyer's pure damage will mop up Primal Split's units very quickly.
Lina
* Puck can dodge Lina's Dragon Slave and Light Strike Array with his 
Phase Shift skill, which helps him avoid combining these abilities with Laguna Blade and avoid burst damage from Lina.
* Puck forbids Lina to use her abilities with the 
Waning Rift ability, which will help her teammates survive and even give them the opportunity to kill her.
Additional:
* Puck can dodge Lina's Dragon Slave and Light Strike Array with Phase Shift. A good Puck player can even dodge Laguna Blade, as it has an invisible projectile, therefore avoiding all the burst damage from Lina.
* Puck forbids Lina to use her abilities with Waning Rift, which will help Puck's teammates survive and even give them the opportunity to kill her.
Lina
* 
Spectral Dagger and 
Haunt allow Spectre to get close to Lina.
* 
Desolate is very strong against Lina, who's usually a bit isolated in fights because of her high attack and cast range.
* 
Dispersion can mitigate a good portion of Lina's burst damage, allowing Spectre to turn on her afterwards.
Additional:
* Spectre can very easily close the distance on Lina with Haunt and Spectral Dagger, and due to Lina's abysmal mobility without a 
Blink Dagger and terrible health pool and armor, Lina easily gets slaughtered due Desolate.
* Dispersion can mitigate a good portion of Lina's burst damage, allowing Spectre to turn against her afterwards.
Brewmaster
* 
Hex's instant cast time will force Brewmaster into the awkward situation of needing some form of spell immunity or block to prevent being immediately hex upon blinking in, or wait until Lion has used all his crowd control before entering a fight. His direct magic burst also makes Brewmaster's Drunken Brawler worthless versus Lion.
Brewmaster
* 
Ancient Seal's instant cast time will often silence Brewmaster before he can do anything.
* Brewmaster also has no defense against Skywrath Mage's massive magical damage.
Lina
* Ember Spirit absorbs quite a large amount of magical damage with its 
Flame Guard, and in addition dodges the abilities of Dragon Slave and Light Strike Array with its 
Sleight of Fist
Additional:
* Ember Spirit absorbs quite a large amount of magical damage with its Flame Guard, and in addition dodges the abilities of Dragon Slave and Light Strike Array with its Sleight of Fist.
Brewmaster
* Brewmaster is slow and has low armor, making his laning stage very difficult against Geminate Attack.
* Apart from the slow moving 
Hurl Boulder, which can be disjointed, he has no control to catch Weaver.
Lina
* Sven has a high health pool and is a natural 
Black King Bar holder and is very hard to kill for Lina.
* Sven also has high physical damage, making it easy for him to burst her down.
Lina
* 
Viper Strike prevents buildup of Fiery Soul stacks.
* 
Corrosive Skin provides magic resistance against Lina's spells. However, Lina can counter this with 
Silver Edge, a common item on Lina.
* 
Poison Attack and Viper Strike can burn away Lina's small health pool.
Lina
* Heroes who have most or all their abilities (damage or disable) unable to pierce spell immunity: 
Keeper of the Light, Lina, 
Lion, 
Zeus.
Additional:
* 
Rage protects Lifestealer from all of Lina's abilities. However, Lina can paritally counter this if played as Carry, a common role for Lina.
* 
Open Wounds from 
Aghanim's Shard can severely slow down Lina and allow Lifestealer and his allies to recover themselves by attacking her.
* Aghanim's Scepter upgraded 
Infest can be used to disarm Lina even if she is spell immune, rendering her unable to maximize the effect of her 
Fiery Soul and force her to use her abilities more often than intended. And Lina's only way to counter this is with 
Linken's Sphere
Lina
* Heroes with spell immunity unless Lina chooses to play Carry role like 
Lifestealer with Rage and 
Juggernaut with 
Blade Fury.
Lina
* Heroes with long animations can be frequently interrupted with Cold Snap: 
Earthshaker, 
Monkey King, 
Shadow Fiend Lina
Lina
* Heroes with a lot of burst damage, especially those who rely on casting spells: Lina, Zeus.
Lina
* Nether Ward will be problematic for heavy nukers and spammers like 
Skywrath Mage, Lina, Lion and 
Invoker, but Pugna must not use Decrepify defensively against them as he will be helping them out more than anything.
Lina
* Heroes with low mobility that rely on spells: Zeus, Lina, 
Crystal Maiden.
Lina
* Squishy heroes (
Io, Crystal Maiden, Lina...), as Earth Spirit can deal tons of damage with Magnetize.
Lina
* Marci can be effective against vulnerable squishy heroes that cannot deal with heroes that jump onto them - 
Sniper, 
Drow Ranger, Lina, 
Rubick, etc.
Lina
* 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.
Brewmaster
* 
Hex's instant cast time will force Brewmaster into the awkward situation of needing some form of spell immunity or block to prevent being immediately hex upon blinking in, or wait until Shaman has used all his crowd control before entering a fight.
* Brewmaster also has no defense against Shadow Shaman lockdowns.
Lina
* Heroes with summons and illusions can find themselves easily bested by Lina, like 
Broodmother, 
Nature's Prophet, 
Chen, 
Terrorblade, 
Naga Siren, 
Visage, 
Wraith King, 
Lycan, 
Phantom Lancer, 
Shadow Shaman.
Brewmaster
* After Brewmaster has committed Thunder Clap and Cinder Brew to gank, Bane can use 
Nightmare on Brewmaster to wait out the debuffs, and might even turn the tables by buying time for allied reinforcements.
* Bane can also prevent Brewmaster from using Primal Split with his long disables.
Lina
* Heroes who have channeled abilities can be stunned by Light Strike Array, like 
Witch Doctor with 
Death Ward and 
Bane's 
Fiend's Grip.
Brewmaster
* 
Exorcism kills Primal Split's units very quickly.
Lina
* Heroes that can kill Death Prophet with nukes can prevent her from using Exorcism to its full duration or using it at all: Lina, Lion, 
Puck, 
Morphling.
Lina
* 
Dark Pact can be cast during the cast animation of Light Strike Array and dispel its stun.
* 
Pounce allows Slark to close the gap to Lina.
* 
Shadow Dance prevents Lina from killing Slark with her Laguna Blade when his HP gets low.
Lina
* Heroes with heavy magical nukes will take advantage of Slark's poor HP or force him to use Shadow Dance early: Lina, Lion, Zeus
Lina
* 
Time Walk will easily backtrack Lina's burst damage (especially Laguna Blade) if not timed correctly.
* During 
Chronosphere, squishy heroes like Lina will be main target of Faceless Void in his ultimate.
Brewmaster
* In general, Brewmaster's Cinder Brew and Thunder Clap makes him good against physical damage carries: 
Ursa, 
Clinkz, 
Faceless Void, 
Troll Warlord, 
Templar Assassin, 
Phantom Assassin.
Additional:
* 
Thunder Clap and 
Drunken Brawler prevent Faceless Void from maximising his damage potential in fights.
* 
Cyclone disables Faceless Void during Chronosphere or in general.
Lina
* 
Doppelganger can be used to easily dodge Light Strike Array if timed correctly.
* While Lina can clear Phantom Lancer's illusions with her abilities, Phantom Lancer can quickly deplete Lina's mana pool with his illusions and deal massive damage from it simultaneously since Phantom Lancer is a natural 
Diffusal Blade carrier.
Lina
* Heroes with summons and illusions can find themselves easily bested by Lina, like Broodmother, Nature's Prophet, Chen, Terrorblade, Naga Siren, Visage, Wraith King, Lycan, Phantom Lancer, Shadow Shaman.
Lina
* 
Guardian Angel is generally useless against Lina as she primarily relies on magical damage. Lina can also dispel it with 
Eul's Scepter of Divinity as she is a hero who often goes for it. Eul's Scepter of Divinity can later be upgraded into 
Wind Waker, which will allow Lina to escape from Omniknight.
* Laguna Blade can often finish off Omniknight's allies before he can save them with 
Purification and 
Repel. This can become even worse once Lina picks Laguna Blade damage is pure and pierces spell immunity talent, which will allow it to ignore both, any form of spell immunity and Guardian Angel.
Brewmaster
* 
Dispel Magic from {U:Storm} instantly removes Heavenly Grace and Guardian Angel from Omniknight's allies in its radius of effect.
Lina
* Lina interrupts Huskar on the center line because of her attack range, she can constantly be at a long distance, punching Huskar with her hand, while Huskar needs a very close distance to use 
Burning Spear
Additional:
* Lina can interrupt Huskar on the center line because of her attack range, she can constantly be at a long distance, punching Huskar with her hand, while Huskar needs a very close distance to use Burning Spear.
Brewmaster
* Brewmaster can use Cyclone to disable Huskar's healer for much longer than most other heroes can, to make Huskar vulnerable.
* Huskar has no way to stop Brewmaster from using Primal Split by himself, but can cut a good amount of his high health away if Huskar's team wants to burst Brewmaster down during a different disable.
Lina
* Lina builds 
Shadow Blade (and upgrades it into a Silver Edge), which makes it hard for Ancient Apparition to land his abilities.
* Laguna Blade can kill Ancient Apparition easily due to his low health pool and lack of mobility.
Brewmaster
* 
Primal Split makes Brewmaster invulnerable for the duration, rendering effects of Cold Feet and Ice Blast useless.
* Dispel Magic can dispel Cold Feet from allies.
* Brewmaster can easily run Ancient Apparition down with the slow from Thunder Clap and 
Cinder Brew.
Lina
* Heroes with summons and illusions can find themselves easily bested by Lina, like Broodmother, Nature's Prophet, Chen, Terrorblade, Naga Siren, Visage, Wraith King, Lycan, Phantom Lancer, Shadow Shaman.
Brewmaster
* Brewmaster can waste a large portion of Lycan's ultimate by putting him in Cyclone.
* Lycan has no way to stop Brewmaster from using Primal Split by himself.
* Lycan's team often tries to push towers as a group, and Brewmaster excels at winning teamfights while trying to defend a tower.
Lina
* Light Strike Array in combination with Dragon Slave can easily clear Broodmother's spiders.
* Laguna Blade offers extensive damage that can kill Broodmother early on or before she is able to use Insatiable Hunger in attempts to salvage a fight.
Brewmaster
* Heroes who produce many summons will have a hard time against Storm's Dispel Magic during teamfight: Broodmother, 
Enigma, Nature's Prophet.
Lina
* Lina's damage burst can quickly kill Clinkz before he saves them with 
Skeleton Walk.
* Fiery Soul attack speed bonus removes 
Burning Army easily in all stages of the game.
Brewmaster
* In general, Brewmaster's Cinder Brew and Thunder Clap makes him good against physical damage carries: Ursa, Clinkz, Faceless Void, Troll Warlord, Templar Assassin, Phantom Assassin.
Lina
* Both Lion's 
Finger of Death and Lina's Laguna Blade have a 0.25 second delay before the damage is dealt.
Lina
* Lina is a common Eul's Scepter of Divinity carrier which can waste some duration of Borrowed Time and following up with Laguna Blade if timed correctly.
Brewmaster
* {U:Storm} can use Cyclone on Abaddon when he activates Borrowed Time, wasting its duration.
* Drunken Brawler and Thunder Clap hinder Abaddon from applying Curse of Avernus' silence on him.
Additional:
* Dispel Magic can remove Abaddon's 
Aphotic Shield or 
Curse of Avernus on an allied hero.
* Cyclone's lengthy duration wastes much of 
Borrowed Time's duration.
Lina
* Heroes with summons and illusions can find themselves easily bested by Lina, like Broodmother, Nature's Prophet, Chen, Terrorblade, Naga Siren, Visage, Wraith King, Lycan, Phantom Lancer, Shadow Shaman.

Brewmaster
* Heroes with area dispel can kill multiple skeletons at once: Brewmaster, 
Oracle.
Lina
* Fragile support heroes are all ideal targets for the Phantom Assassin. Heroes such as Lina and Witch Doctor are all prime targets that may not be able to react quickly and fight back due to Phantom Assassin's sudden appearance.
Lina
* Laguna Blade is one of the best tools to kill Phantom Assassin before she can do anything in early-to-mid game due to its high magical (pure with Laguna Blade damage is Pure and pierces Spell Immunity talent) burst damage.
* 
Blur offers no protection against Lina's abilities. Likewise, Lina can counter Blur's evasion by buying either Silver Edge or 
Monkey King Bar.
* Lina just has to be careful about 
Fan of Knives from Aghanim's Shard and 
Coup De Grace, as Fan of Knives can deal pure damage to Lina and disable Fiery Soul awhile Coup De Grace can deal serious damage to her even if she is spell immune, which may force Lina to buy 
Ethereal Blade to deal with Phantom Assassin.

Brewmaster
* In general, Brewmaster's Cinder Brew and Thunder Clap makes him good against physical damage carries: Ursa, Clinkz, Faceless Void, Troll Warlord, Templar Assassin, Phantom Assassin.
Lina
* Lina has very high magic burst damage to use against the low-health-pool Luna. Laguna Blade can also be upgraded with Laguna Blade damage is Pure and pierces Spell Immunity to bypass Black King Bar, making Lina even more of a threat. Luna however, can easily counter this problem with Linken's Sphere, which is a common item for her.
* For the same reasons, Lina makes a very powerful ally for Luna when they are in the same team.
Lina
* Lina's high damage burst from Dragon Slave, Light Strike Array and Laguna Blade can easily kill Chen's allies or Chen himself before he can use 
Hand of God.
Additional:
* Lina's high damage burst from Dragon Slave, Light Strike Array and Laguna Blade can easily kill Chen's allies or Chen himself before he can use Hand of God.
Lina
* Enchantress has a very small health pool and cannot tank Lina's heavy magic burst.
* Untouchable is decently countered by Fiery Soul, exposing Enchantress's weakness to physical damage due to her low armor.
* Lina is decent at clearing creeps and can kill Enchantress's creeps quickly.
Additional:
* Enchantress has pitiful health, and cannot tank Lina's heavy magic damage.
* 
Untouchable is decently countered by Fiery Soul, exposing Enchantress's weakness to physical damage due to her low armor.
* Lina is decent at clearing creeps and can kill Enchantress' creeps quickly.
Lina
* Dragon Slave deals reliable magic damage during the laning phase against Mars.
* Lina's Eul's Scepter of Divinity and Light Strike Array combo can interrupt Mars from being disruptive for a decent amount of time and leave him vulnerable for follow up stuns.
* Laguna Blade deals massive magical damage, and pure damage with Aghanim's Scepter.
Lina
* Lina can outlanes Shadow Fiend on the central line, due to the fact that Lina's attack range exceeds the attack range of Shadow Fiend, which makes it difficult for him to fend off her attacks and approach creeps, thus Lina has more level and gold.
* Lina can defeat Shadow Fiend with the combination of her abilities on lane and during teamfights: Light Strike Array, Dragon Slave, Laguna Blade, Shadow Fiend does not have a large pool of health before buying items for extra strength and health like 
Satanic, which is why Lina's strong magic damage is enough to kill him quickly.
Additional:
* Outlanes Shadow Fiend on the central line, due to the fact that Lina's attack range exceeds the range of Shadow Fiend, which makes it difficult for him to fend off her attacks and approach creeps, thus Lina has more level and gold
* Defeats Shadow Fiend` from Burst with a combination of skills: Light Strike Array, Dragon Slave, Laguna Blade, Shadow Fiend does not have a large pool of health before buying an item: Satanic , which is why Lina's strong magic damage is enough to kill him quickly
Brewmaster
* Cinder Brew and Drunken Brawler makes it hard for Monkey King to stack Jingu Mastery.
* Cyclone can remove Monkey king for 6 seconds if his allies lack dispels.
* Dispel Magic can dispel Jingu Mastery's bonuses.
Lina
* Light Strike Array and Dragon Slave allows Lina to destroy trees, countering 
Nature's Guise and 
Eyes in the Forest.
* Lina has many tools to bypass 
Living Armor's protection.
Lina
* Lina defeats Sniper on the mid, because she has the same attack range as him, and her Dragon Slave ability deals much more damage to creeps, as well as to Sniper himself, than 
Shrapnel, which creates uncomfortable conditions for Sniper to farm on the line, which is why Lina either punches Sniper harder than he either pushes a pack of creeps up to the tower and finishes off his creeps under it, preventing Sniper from earning gold and a level.

Lina
* Being a hero with low health and abysmal mobility, Lina can nuke her down easily.
* Since Crystal Maiden's 
Freezing Field is a channeled ability, Lina can use her Light Strike Array to cancel it easily.
Brewmaster
* Storm's Dispel Magic combined with Thunder Clap deals high damage against Chaos Knight's illusions even in the late game.
* Chaos Knight's reliance on physical damage is easily hindered by Drunken Brawler.
* Chaos Knight's lack of area effect and mobility makes him easily overwhelmed by Primal Split.
Additional:
* Dispel Magic from {U:Storm} can instantly kill Phantasms early on, and can still deal a lot of damage to them late game, revealing the real Chaos Knight.
Lina
* Venomancer has low health, which makes him vulnerable to Lina's heavy magic damage.
* Fiery Soul attack speed bonus removes 
Plague Wards easily in all stages of the game.
Lina
* Laguna Blade is one of the best tools to kill Terrorblade before he can use 
Sunder due to its high magical damage.
* Dragon Slave and Light Strike Array allows Lina to clear Terrorblade's illusions from both, Conjure Image and 
Manta Style.
* Lina commonly buys items that allow her attacks to deal magical damage to Terrorblade that can ignore his high armor, like 
Gleipnir, Monkey King Bar or 
Revenant's Brooch.
Additional:
* Laguna Blade is one of the best tools to kill Terrorblade before he can use Sunder due to its high magical (pure with Laguna Blade damage is Pure and pierces Spell Immunity talent) burst damage.
* Dragon Slave and Light Strike Array allows Lina to clear Terrorblade's illusions from both, Conjure Image and Manta Style.
Lina
* Dragon Slave will make quick work of the spawned illusions from Disruption.
* An attempt to save an ally using Disruption can easily become a perfect setup for a Light Strike Array for the enemy.
* Shadow Demon doesn't have the burst damage to take Lina out of the fight quickly, although Demonic Purge can help his allies kill a squishy Lina.
Lina
* Laguna Blade ends Gyrocopter very quickly in the early to mid game.
Lina
* 
Ghost Shroud is not a good defensive ability against Lina as all of her abilities deal magical damage.
* Lina has a very long range of attack, which completely overlaps the range of 
Death Pulse and 
Heartstopper Aura.
* However, once Necrophos gets Aghanim's Shard, he will gain access to 
Death Seeker which will allow him to turn into a larger Death Pulse that can be used to close the gap on Lina and kill her if she is not careful.
Additional:
* Laguna Blade's damage as well as damage from all of Lina's abilities will be greatly amplified during Ghost Shroud.
Lina
* 
Moonlight Shadow does little good against Dragon Slave and Light Strike Array.
* Lina's damage burst can quickly kill Mirana's teammates before she saves them with Moonlight Shadow.
Additional:
* Eul's Scepter of Divinity is an item Lina commonly buys, which in combination with and Light Strike Array can disable Mirana if she tries to Leap away.
* Laguna Blade's magical (pure with Laguna Blade damage is Pure and pierces Spell Immunity talent) burst damage takes advantage of Mirana's below average health.
Brewmaster
* Brewmaster can make the Spirit Bear a much smaller threat with Cinder Brew.
* Cyclone removes the bear from a fight so that his team can easily focus on the hero.
* While most heroes would be worn down by a Spirit Bear 
Radiance in the time it takes to kill Lone Druid, Brewmaster is protected in Primal Split.
Lina
* Light Strike Array catches Morphling while he jumps in from 
Waveform and also prevents Morphling from using his abilities.
* Laguna Blade can kill Morphling quickly before he shifts into 
Attribute Shift (Strength Gain).
Brewmaster
* {U:Earth} has passive 
Spell Immunity, allowing him to walk into the Echo Stomp radius to stun Elder Titan with his Hurl Boulder.
* {U:Storm}'s Cyclone can cancel the channeling of Echo Stomp and take Elder Titan out of the fight for {show:A|Storm|Cyclone|value2} seconds.
Lina
* Light Strike Array can catch Meepo and his clones off-guard if he tries to gank Lina with 
Earthbind & 
Poof.
* Laguna Blade can quickly kill Meepo and his clones before they escape with Poof.
Lina
* Since Windranger is bad against magical damage, heroes with continuous magical damage or magical nukes can blast her: Zeus, 
Tinker, Leshrac, 
Viper, Skywrath Mage, Lion, Lina, 
Venomancer.
Lina
* Heroes with high physical and magical damage alike are a huge hazard for Muerta, as they can deal serious damage to her even if she has 
Pierce the Veil active: Luna, Lina, 
Tusk, Broodmother, Shadow Fiend, 
Ember Spirit, 
Gyrocopter, Vengeful Spirit, 
Arc Warden, 
Medusa, Shadow Shaman.

Brewmaster
* In general, Brewmaster's Cinder Brew and Thunder Clap makes him good against physical damage carries: Ursa, Clinkz, Faceless Void, Troll Warlord, Templar Assassin, Phantom Assassin.
Lina
* Heroes with powerful spammable abilities will prove problematic for Grimstroke as Ink Swell does not protect him from them: Zeus, Skywrath Mage, Tinker, Lina
Lina
* Heroes who have channeled abilities can be stunned by Light Strike Array, like Witch Doctor with Death Ward and Bane's Fiend's Grip.
Additional:
* Light Strike Array cancels out Death Ward from a long distance.
Lina
* Heroes who rely on armor or evasion to survive can easily be bursted down, like Phantom Assassin, Terrorblade, Underlord, Spirit Breaker.
Lina
* 
Mind Flare does tons of damage against Lina because of her high intelligence.
* 
Vendetta can deal heavy damage to Lina while also burning her mana, preventing Lina from casting her abilities.
* 
Spiked Carapace can easily be used to counter Lina's abilities because of their long cast animation, and could probably kill Lina outright if Laguna Blade is reflected. However, Lina can counter this with Eul's Scepter of Divinity, a common item on Lina.
Lina
* Heroes who build Black King Bar as either core or situational item will be able to fight back against Nyx Assassin and freely attack him as Spiked Carapace cannot pierce spell immunity at all: 
Axe, Broodmother, Dawnbreaker, Enigma, Huskar, Jakiro, 
Legion Commander, Lina, Luna, Lycan, 
Slardar, 
Slark, Troll Warlord, Witch Doctor.
Brewmaster
* Cyclone from Storm in Primal Split can waste Nyx's Spiked Carapace, since its duration is shorter than the Cyclone's.
Lina

Additional:
* Laguna Blade can kill Dazzle quickly before he casts 
Shallow Grave.
Lina
* Any hero with high attack speed will be a threat to Phoenix when it initiates, as they can easily tear down a 
Supernova, perhaps even while debuffed by Fire Spirits: Juggernaut, Clinkz, Troll Warlord, 
Beastmaster, Lina.
Lina
* Heroes with either magical, physical or pure damage burst: Bane, Ember Spirit, Leshrac, Lina, Luna,

Brewmaster
* Blinking heroes like 
Anti-Mage or 
Queen of Pain can often chase down an injured Brewmaster after his ultimate expires.
Lina
* Lina has a very long range of attack, which completely overlaps the range of Queen of Pain's abilities and attacks, which is why even a single 
Shadow Strike roll can become deplorable, since Lina will shoot Queen of Pain from a long distance before and after the Shadow Strike roll. And with the help of the abilities of Light Strike Array and Laguna Blade, Lina can even kill Queen of Pain because of her small health reserve if she is exposed to a blow

Lina
* 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.
Lina
* Pudge has low armor and mobility, making him suspectible to her physical attacks (if Lina is the carry).
* Because 
Dismember is a channeled ability, it can be canceled through Light Strike Array within a distance.
Lina
* 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.
Lina
* Lina can burst Vengeful Spirit down, provided she can land Light Strike Array before Vengeful Spirit lands her Magic Missile.
* Laguna Blade deals massive damage, often being enough to kill a squishy Vengeful Spirit.
Lina
* Heroes that can close the gap can easily chase Lina down, such as Timbersaw with 
Timber Chain and Anti-Mage with 
Blink.
Lina
* Timbersaw has a difficult time against magical and pure damage: Lina, Leshrac, 
Enchantress, Queen of Pain
Lina
* Storm Spirit can quickly close the distance with Lina using

* Lina can win on a line against Storm Spirit because of the range of her abilities and attacks, and Storm Spirit will be forced to survive on such a line, not farm
Lina
* Templar Assassin can outmatch Lina on the center line thanks to her own 
Psi Blades, which is why the advantage of Lina's long-range attacks become turned against her.
* 
Refraction is good defense against Lina's burst damage. But remember that Lina can partially counter this with Dragon Slave's damage over time.
Additional:
* Outlanes Lina on the center line thanks to her own Psi Blades, which is why the advantage of Lina's long-range attacks become turned against her
* Closes from Lina's magic attacks with her own Refraction, which is why Lina can't make her combination: Light Strike Array, Dragon Slave, Laguna Blade and kill Templar Assassin quickly
Brewmaster
* The three Primal Split brewlings all attacking Templar Assassin at once will remove her Refraction quickly, especially with Fire's Permanent Immolation.
* Templar Assassin has no way to stop Brewmaster from using Primal Split by herself, and may get unlucky and miss her 
Meld if trying to burst him during her ally's disable.
Lina
* Light Strike Array has a long delay, making her vulnerable for Ursa's burst.
* Enrage can protect Ursa against Lina's high magical burst.
Brewmaster
* If Ursa uses 
Enrage Brewmaster can use Cyclone to render him harmless during his ultimate.
* Brewmaster has two spells to slow down Ursa, allowing his team to kite around him easily.
Lina
*
Blink allows Anti-Mage to get on top of Lina and deal damage with his 
Mana Break.
Counterspell makes Anti-Mage tanky against Lina's heavy magic damage. It can also be used block and reflect Laguna Blade.
Mana Void is very hazardous for Lina, who has a high mana pool and quickly depletes it during fights.

Brewmaster
* Blinking heroes like
Anti-Mage or 
Queen of Pain can often chase down an injured Brewmaster after his ultimate expires.
