Lich
* Heroes that depend on disrupting fights with ability combos or big ultimate abilities are vulnerable to the long stun of Fiend's Grip: 
Disruptor, 
Death Prophet, 
Enigma, 
Faceless Void, 
Invoker, 
Lich, 
Magnus, 
Mars, 
Medusa, 
Outworld Destroyer, 
Phoenix,

Queen of Pain, 
Shadow Fiend, 
Treant Protector, 
Underlord, 
Winter Wyvern, 
Witch Doctor, 
Zeus.
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.
Lich
* Lich is heavily reliant on his abilities to contribute to team fights, so be wary of enemies that can Silence: 
Bloodseeker, Death Prophet, 
Silencer, 
Drow Ranger, 
Skywrath Mage.
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.

* Lich is heavily reliant on his abilities to contribute to team fights, so be wary of enemies that can Silence: Bloodseeker, Death Prophet, Silencer, Drow Ranger, Skywrath Mage.
Brewmaster
* 
Exorcism kills Primal Split's units very quickly.
Lich
* Queen of Pain can easily escape Chain Frost thanks to 
Blink.
* His low survivability makes an easy kill for 
Shadow Strike, 
Scream of Pain & 
Sonic Wave.
Brewmaster
* Blinking heroes like 
Anti-Mage or Queen of Pain can often chase down an injured Brewmaster after his ultimate expires.
Lich
* Anti-Mage can withstand magical burst damage much better than other carries, making him effective against nukers: Lich, 
Necrophos, 
Oracle, and 
Leshrac.
Additional:
* Although he can be effective against Anti-Mage in an aggro offlane, Lich has a hard time nuking down Anti-Mage in the midgame due to his Counterspell.
* All of Lich's abilities are also targeted, which makes it much harder to disable Anti-Mage.
* In the lategame, Anti-Mage can easily pick off Lich with 
Blink, and the high mana cost of Chain Frost along with Lich's large mana pool makes him vulnerable to 
Mana Void.
* Blink allows Anti-Mage to escape Chain Frost.
Brewmaster
* Blinking heroes like Anti-Mage or Queen of Pain can often chase down an injured Brewmaster after his ultimate expires.
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.
Lich
* Bloodseeker is not affected by slows when he is affected by 
Thirst.
* If he sees Chain Frost is targeting him, he can easily isolate himself with the movement speed buff from Thirst so that it stops bouncing around.
* Lich heavily relies on his abilities to contribute to team fights, making 
Blood Rite effective against him.
Brewmaster
* Outworld Destroyer's pure damage will mop up Primal Split's units very quickly.
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.
Lich
* Lich does not pose a big threat to Zeus in teamfights, as his spells don't have great cast range and Zeus should be too far back for a 
Chain Frost to bounce among him and his allies.
* Lich has a low health pool, allowing Zeus to burst him down quickly.
Lich
* Heroes with low health: Lich, 
Crystal Maiden, 
Lion.
Lich
* Heroes with low health will die easily during Duels, and can be farmed for damage in the early game: Crystal Maiden, Lich, 
Techies, 
Rubick
Lich
* The haste provided by 
Dark Seer's 
Surge or a {Rune:Haste} renders Lich's slows ineffective.
Lich
* Lich is heavily reliant on his abilities to contribute to team fights, so be wary of enemies that can Silence: Bloodseeker, Death Prophet, Silencer, Drow Ranger, Skywrath Mage.

Brewmaster
* Heroes with strong team-fight abilities (especially ultimates) like 
Tidehunter, 
Brewmaster, Death Prophet, etc.
Lich
* Heroes who lack burst damage will have a hard time against Mars: 
Phantom Lancer, 
Nature's Prophet, Lich.
Lich
* Phantom Assassin can easily escape Lich's slows with 
Phantom Strike.
* Phantom Assassin's 
Coup De Grace can be used to burst down the squishy Lich.
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.
Lich
* Chain Frost can bounce to the treants that Nature's Prophet summons.
* Nature's Prophet's 
Sprout can be used to isolate and burst down the squishy Lich.
Additional:
* His treants can prevent Chain Frost from jumping to Nature's Prophet or his allies.
Brewmaster
* Heroes who produce many summons will have a hard time against Storm's Dispel Magic during teamfight: 
Broodmother, Enigma, Nature's Prophet.
Lich
* Lich's Chain Frost, especially after obtaining its respective talent that provides unlimited bounces, can take out all of Chaos Knight's illusions quickly.
* An 
Aghanim's Scepter-upgraded 
Sinister Gaze can hypnotize Chaos Knight and his illusions while also draining his already low mana pool.
Additional:
* Chain Frost can eliminate Chaos Knight's 
Phantasm army, especially after he clumped up using 
Reality Rift.
* Frost Shield will heavily reduce his army's effectiveness.
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.
Lich
* Chain Frost can deliver high amounts of damage to Lone Druid itself and his bear if they do not separate fast from each other.
Additional:
* Chain Frost will bounce between Lone Druid and his bear, forcing them to separate or suffer high amounts of damage.
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.
Lich
* 
Frost Shield helps offset the armor reduction from Natural Order.
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.
Lich
* 
Frost Blast and Chain Frost can kite Troll Warlord effectively.
* Frost Shield can single-handedly waste most of the duration of Battle Trance, due to the extreme resistance to physical damage Frost Shield provides. In addition, Troll Warlord is incapable of switching targets during Battle Trance, so he cannot pick an easier target.
* Troll Warlord has little to no ability to regenerate HP, so Frost Blast together with Frost Shield can harass him effectively.
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.
Lich
* Heroes with large magical AoE damage will fare well against Omniknight: Lich, 
Ancient Apparition, 
Jakiro, Disruptor.
Brewmaster
* Dispel Magic from {U:Storm} instantly removes Heavenly Grace and Guardian Angel from Omniknight's allies in its radius of effect.
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.
Lich
* Lich's constant slows with Frost Blast and Chain Frost will slow Dragon Knight to a crawl, especially in a crowded teamfight.
Brewmaster
* Cyclone from Storm in 
Primal Split can waste Nyx's Spiked Carapace, since its duration is shorter than the Cyclone's.
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.
Lich
* Lich's Chain Frost forces Io to either give up providing buff to his ally with 
Tether or suffer devastating damage with his Tethered ally.
* Lich can easily use Sinister Gaze to disable Io from getting away with Tether or 
Relocate.
Lich
* 
Poof combo puts all of the Meepos very close together, making them vulnerable to Frost Blast's AoE slow and multiple bounces from Chain Frost.
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.
Lich
* Chain Frost can deliver high amounts of damage to Arc Warden and his double if they do not separate fast from each other.
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.
Lich
* Heroes with nukes: 
Bane, Lich, Lion, Skywrath Mage
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.
Lich
* Supports who can slow him to the point Trample does very little damage in the lane are also not fun: Lich, 
Ogre Magi, Winter Wyvern.
Brewmaster
* Brewmaster with Primal Split
* Heroes that can dodge Glimpse:
* Puck with 
Phase Shift
* 
Riki with 
Tricks of the Trade
* Phantom Lancer with 
Doppelganger
* 
Ember Spirit with 
Sleight of Fist and 
Activate Fire Remnant
* 
Chaos Knight with Phantasm
* 
Naga Siren with 
Mirror Image
* 
Tusk with 
Snowball
* 
Juggernaut with 
Omnislash

Brewmaster
* Heroes with area dispel can kill multiple skeletons at once: Brewmaster, Oracle.
Lich
* Heroes with powerful nuke can waste their precious abilites on her Refraction during a ganking attempt or chaos combat: Lich, 
Lina, 
Sniper, Outworld Destroyer Zeus
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.
Lich
* Vulnerable spellcasters with no escape mechanisms are easy targets for Huskar: Lich, Crystal Maiden, Silencer, 
Keeper of the Light, 
Venomancer, etc.
Additional:
* Lich is going to have a hard time nuking Huskar because of his high health regeneration from 
Berserker's Blood.
* Lich is a squishy support without an escape mechanism, making Lich an easy kill thanks to 
Life Break and 
Burning Spear.
* Once Huskar has 
Armlet of Mordiggian, even a maxed out Frost Blast will struggle to finish Huskar off.
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.
Lich
* Lycan doesn't care much about Lich's slows thanks to 
Shapeshift.
* Chain Frost can bounce to the wolves that Lycan summons.
Additional:
* Lich possesses a lot of slows, which Lycan doesn't care about when he Shapeshifts.
* Lich has no in-built escape, which makes him a good target for Lycan.
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.
Lich
* Support heroes with low mobility can be slowed further by Incapacitating Bite, and swarmed by Spiderlings for an easy kill: 
Shadow Shaman, 
Visage, 
Dazzle, Rubick, Lich.
Additional:
* Chain Frost can bounce to the Spiderlings that Broodmother spawns.
Brewmaster
* Heroes who produce many summons will have a hard time against Storm's Dispel Magic during teamfight: Broodmother, Enigma, Nature's Prophet.
Lich
* Weaver doesn't care much about Lich's slows thanks to
Shukuchi.
Time Lapse.
* If he sees Chain Frost is targeting him, he can easily isolate himself with Shukuchi so that it stops bouncing around.
* Unless Lich bursts Weaver immediately, Lich has no hard disables or silences to prevent him from using
Brewmaster
* Brewmaster is slow and has low armor, making his laning stage very difficult against Geminate Attack.
Hurl Boulder, which can be disjointed, he has no control to catch Weaver.
* Apart from the slow moving
