Broodmother
* 
Overwhelming Odds's damage stacks with each enemy unit in its radius. If this hits Broodmother and a large number of spiders it can deal significant amounts of damage.
* 
Moment of Courage has a high chance to proc if Broodmother and all of her spiders are attacking her.
* 
Duel can keep Broodmother in place long enough for Legion's team to kill her.
Additional:
* Overwhelming Odds is great at killing many stacked up spiderlings, thus giving Legion Commander a large buff.
* Duel is a reliable way to lock down Broodmother, preventing her from running into the treeline.
Primal Beast
* Duel prevents Primal Beast from using all of his spells and stops all of his damage output.
* Moment of Courage will not proc if Primal Beast is using Trample so you may want to play around with that if you're looking for duel damage with a 
Blade Mail.
* 
Press the Attack can be used to dispel Pulverize immediately and make allies survive Trample for a short duration with the heal.
Broodmother
* Your AoE abilities should make quick work of her spiderlings.
Primal Beast
* 
Diabolic Edict makes Leshrac very effective at threatening early towers and objectives which can directly cause unfavorable conflicts with Primal Beast early before he has 
Black King Bar to deal with the magical damage.
* 
Pulse Nova and the rest of Leshrac's spells can overwhelm Primal Beast with magical damage.
* Leshrac has generally faster movement speed than Primal Beast, especially if he has items such as 
Boots of Travel and 
Eul's Scepter of Divinity.
* 
Bloodstone also makes him heal much more than Primal Beast can damage him at any stage of the game.
Broodmother
* Heroes with area of effect abilities that increase in power based on the number of units struck: 
Earthshaker, 
Legion Commander, 
Grimstroke.
Additional:
* Stroke of Fate can deal heavy damage to Broodmother and her spiders, and with enough spiders it can kill her instantly.
* Phantom's Embrace provides vision on Broodmother when she's fleeing into the trees.
Primal Beast
* Any ganking heavy support can be a big problem for Primal Beast, such as: 
Earth Spirit, Grimstroke before he has a Black King Bar.
Broodmother
* 
Broodmother, 
Nature's Prophet, 
Phantom Lancer by their nature offer very good target for Splinter Blast and Winter's Curse.
Primal Beast
* 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.
Broodmother
* 
X Marks the Spot prevents Broodmother from escaping.
* 
Tidebringer can clear Broodmother's spiders if they get in range.
Additional:
* Kunkka's entire kit is great for taking out multiple units at once.
* Tidebringer's cleave will split through a wave of spiderlings.
* X Marks the Spot is great for dragging Broodmother back out of her web for Kunkka's team to set up on her.
* Torrent and Ghostship will demolish any spiderlings within the radius.
Broodmother
* 
Echo Stomp can impede Broodmother's ability to push towers due to its low cooldown and long sleep duration.
* 
Astral Spirit can provide Elder Titan large amounts of damage, armor, and movement speed from her spiderlings.
* 
Natural Order negates Broodmother and her spiderling's base armor and magic resistance, increasing most damage dealt to them.
Primal Beast
* The ensnare from melee 
Berserker's Rage can prevent Primal Beast from dealing further Trample damage and can allow Troll Warlord to relentlessly build 
Fervor on him.
* 
Whirling Axes (Ranged) can slow down Primal Beast while trampling and allow Troll Warlord to better control him from range.
* 
Whirling Axes (Melee) can blind Primal Beast if he attempts to auto-attack Troll Warlord after a fully charged Uproar.
* 
Battle Trance will make Primal Beast a sitting duck should he be rooted and attacked to death. However, using Pulverize after this can render Troll Warlords ultimate completely useless.
Broodmother
* Broodmother and her Spiderlings need to be very careful during the laning stage against Jakiro, as Jakiro can take down Broodmother's Spiderlings, preventing her from pushing as well as gaining a good amount of gold.
Broodmother
* 
Earthbind prevents Broodmother from escaping Meepo's attacks.
* 
Poof will quickly clear any nearby spiders.
* Broodmother often picks off single target heroes. With Meepo's 
Divided We Stand, it gets a lot harder once every Meepo Poofs in.
Broodmother
* 
Aftershock in combination with 
Enchant Totem prevents Broodmother from continuing to attack Earthshaker without being repeatedly stunned.
* 
Echo Slam is greatly amplified by Spiderlings, often instantly killing Broodmother, her swarm, and anyone else unfortunate enough to be nearby.
* Earthshaker's vast amount of stuns makes it difficult for Broodmother to continue attacking enemies (to continue lifestealing with Insatiable Hunger) without Black King Bar.
Additional:
* Echo Slam's damage potential increases phenomenally due to Broodmother's hordes of spiderlings and spiderites.
* Long ranged Fissures can hit Broodmother if she runs into the treeline at the edges of the map.
Broodmother
* 
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.
Broodmother
* 
Death Pulse can easily wipe out Broodmother's spiderlings if they're too close while also offering Necrophos a source of regeneration for Broodmother's harass in lane.
* 
Ghost Shroud prevents Broodmother or her spiderlings from damaging Necrophos temporarily until Broodmother buys 
Nullifieror 
Revenant's Brooch.
* 
Heartstopper Aura will regenerate lost health and mana for every spiderling or spiderite Necrophos manages to kill.
Primal Beast
* 
Borrowed Time allows him to both exit his stuns prematurely and turn Trample into healing for himself. His Aghanim Scepter only prevents the automation of the spell, Abaddon himself can still manually activate it.
* 
Aphotic Shield will immediately debuff any stuns Primal Beast has put on allies but won't stop him from being stunned if casted on Abaddon.
Primal Beast
* 
Shukuchi allows Weaver to have faster movement speed and can outrun Primal Beast in most instances, such as while he is trampling.
* Trample disarms Primal Beast, so casting 
The Swarm can make him vulnerable to ranged attacks. Primal Beast also has an innately slow attack speed and will take a long time destroying the bugs.
* 
Time Lapse allows Weaver to negate and heal burst damage, which Primal Beast is reliant on.
Broodmother
* 
Burrowstrike can be used as an escape or initiation against Broodmother.
* 
Sand Storm quickly kills any spiderlings caught inside if Sand King can manage to stun them.
Additional:
* Caustic Finale allows Sand King to easily kill Broodmother's Spiderlings throughout the game.
* Sand King can usually catch a split pushing Broodmother with 
Blink Dagger and Burrowstrike.
Primal Beast
* Primal Beast's abilities require movement to deal damage, making 
Rupture potentially deadly and debilitating. Furthermore, its initial damage based on the target's current health is devastating to a full-health Primal Beast with his high strength gain and thus high HP.
* Due to his reliance on spells, Primal Beast is vulnerable to 
Blood Rite's powerful silence without items to counter it. While silenced, Primal Beast cannot use Pulverize to defend himself.
Broodmother
* Alchemist can easily farm Spiderlings with Acid Spray and Greevil's Greed.
* Alchemist's Chemical Rage nullifies Broodmother's 
Insatiable Hunger
Additional:
* 
Greevil's Greed makes Broodmother’s spiderlings far more valuable to Alchemist making it important that he does farm them as opposed to other heroes where the spider's bounties are negligible.
* 
Acid Spray makes it difficult to attack Alchemist in lane without losing some spiderlings to the damage over time, potentially giving him farm he wouldn't have otherwise.
Primal Beast
* 
Time Walk makes it impossible for Primal Beast to stay on top of Faceless Void with his abilities and allows him to heal burst damage dealt to him.
* Once Faceless Void has an 
Aghanim's Shard, Onslaught can be easily escaped. He could also choose to get a lower cooldown on Time Walk, making it even harder for Primal Beast to catch him in fights or stop his initiations.
* 
Time Dilation will make Primal Beast useless for an extended time after casting his abilities if he does not have a dispel.
* 
Chronosphere has many uses such as stopping Primal Beast from casting abilities on him or allies or even on a teammate, since Primal Beast has no way to assist allies trapped within the sphere.
Broodmother
* 
Swashbuckle can be used for Pangolier to escape or kill Broodmother's spiders. Combined with 
Lucky Shot Pangolier can potentially disarm Broodmother preventing her from lifestealing off enemies.
* 
Shield Crash can be used for wave clear to deal with Broodmother's spiders.
* 
Rolling Thunder can be used as an escape or a means of initiating on Broodmother.
Additional:
* Swashbuckle and Shield Crash quickly destroys Broodmother's spiderlings and spiderites.
* Lucky Shot's disarm is very valuable when dealing with a Broodmother during her Insatiable Hunger.
Broodmother
* Spiderlings are a good source of farm for 
Necromastery and can be quickly killed with 
Shadowraze.
* Shadow Fiend is a natural Black King Bar carrier, protecting him from any of Broodmother's abilities.
* 
Requiem of Souls combined with Eul's Scepter of Divinity can potentially kill Broodmother before she gets a Black King Bar.
Broodmother
* Quill Spray destroys spiderlings, and hits Broodmother even when she's regenerating in her webs. This makes Bristleback one of her hardest counters in lane.
Additional:
* 
Bristleback reduces most of Broodmother's and her spiderlings' damage.
* 
Quill Spray will hit any spiders in its proximity, hindering Broodmother's fighting and farming capabilities.
Broodmother
* 
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.
Broodmother
* Void Spirit's AoE damage make short work of Broodmother's spiderlings
* Even in she is within the range of her spiderwebs from 
Spin Web Broodmother cannot escape Void Spirit's mobility.
Additional:
* Void Spirit's AoE damage make short work of Broodmother's spiderlings
* Broodmother cannot escape Void Spirit's mobility, even in her webs.
Broodmother
* 
Kraken Shell makes Tidehunter take nearly no damage from Spiderlings.
* 
Anchor Smash kills Spiderlings in one or two casts, should Broodmother try to swarm Tidehunter with them.
Primal Beast
* 
Glimpse can prevent Primal Beast from initiating for most of the game with Onslaught.
* While 
Static Storm is not much of a threat in terms of damage, it does prevent Primal Beast from casting any spells for a long period of time if also trapped in 
Kinetic Field.
* Overall, Disruptor forces Primal Beast to buy a Black King Bar much earlier than he might like but becomes a major threat to Disruptor once he does.
Broodmother
* 
Ball Lightning and 
Electric Vortex will catch Broodmother before she has a chance to retreat, and is able to catch her through the trees.
* Conversely, Ball Lightning also allows him to easily escape Broodmother, as she has no way to prevent him from using it before getting 
Orchid Malevolence.
Broodmother
* 
Breathe Fire will clear Broodmother's spiderites while significantly damaging her spiderlings and decreasing their damage output.
* 
Dragon Blood's added armor and regen mitigates the damage done by Broodmother and her spiders.
* 
Elder Dragon Form at level 2 and above applies splash damage to Dragon Knight's auto attacks.
Broodmother
* Tiny can quickly clear Spiderlings with his active abilities and cleave.
Broodmother
* 
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.
Broodmother
* 
Reactive Armor prevents Broodmother's spiderlings from being able to effectively harass Timbersaw in the lane.
* 
Timber Chain's high mobility makes Silken Bola's slow irrelevant, unless Broodmother already bought her Orchid.
* Silken Bola's miss chance doesnt affect Rizzrack that much because he does not rely on his autoattacks much.
* 
Lotus Orb items for Timbersaw make Silken Bola useless.
* Timbersaw's abilities can destroy any trees that Broodmother attempts to hide in and his AoE abilities can quickly clear her Spiderlings.
Additional:
* Spiderlings deal almost no damage against Reactive Armor. They also die quickly from Timbersaw's AoE abilities.
* Broodmother has no mobility ability except the movement speed buff from Spin Web, allowing Timbersaw to easily escape her 
Silken Bola with Timber Chain.
* Timbersaw's tree-cutting abilities make it difficult for Broodmother to hide, especially near the edges of the map.
Primal Beast
* Primal Beast is mostly played in the offlane role, so picking a carry who can escape from him is essential. Heroes such as 
Troll Warlord, 
Lone Druid and 
Outworld Destroyer, or generally any carry with a stun, slow or ability to fight back will stop him from having the good start he needs.
Broodmother
* Heroes with no AoE abilities will struggle against Phantom Lancer: 
Phantom Assassin, Broodmother
Primal Beast
* Primal Beast is mostly played in the offlane role, so picking a carry who can escape from him is essential. Heroes such as Troll Warlord, Lone Druid and Outworld Destroyer, or generally any carry with a stun, slow or ability to fight back will stop him from having the good start he needs.
Broodmother
* Heroes who produce many summons will have a hard time against Storm's Dispel Magic during teamfight: Broodmother, 
Enigma, Nature's Prophet.
Primal Beast
* 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.
Primal Beast
* 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.
Primal Beast
* Any ganking heavy support can be a big problem for Primal Beast, such as: Earth Spirit, Grimstroke before he has a Black King Bar.
Primal Beast
* 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.
Broodmother
* Mass summoning heroes: Broodmother, Nature's Prophet and Enigma all have summons Puck can clear clear with Illusory Orb and Waning Rift instantly, due to their summons having low health.
Primal Beast
* Like above, supports with reliable stuns can be a massive problem and force Black King Bar in fights unideally, such as 
Shadow Shaman, 
Lion, 
Nyx Assassin.
Broodmother
* Heroes who cannot fight back during Arena of Blood in the early and mid game: 
Abaddon, 
Anti-Mage, Broodmother, 
Luna, 
Sniper, Troll Warlord, 
Weaver, 
Clinkz.
Broodmother
* Heroes reliant on illusions or summons: Broodmother, 
Chaos Knight, 
Naga Siren.
Primal Beast
* Oracle can negate and shut down Primal Beast simply with Fate's Edict, especially in the early game, as a majority of his damage-dealing spells are magic.
* Oracle can interrupt Primal Beast's 
Onslaught charge with a well-timed Fortune's End.
* Primal Beast's lethal burst damage combos can be further stalled with False Promise; combined with Fate's Edict and regen from Purifying Flames, Oracle can even completely negate Primal Beast's offense.
Additional:
* 
Fate's Edict completely negates all of Primal Beast's major damage-dealing spells in the early game and can render Primal Beast useless when cast on a target he is focusing, or in Oracle's defense against Primal Beast himself.
* 
Fortune's End keeps Primal Beast in place, especially while trampling or in the middle of an Onslaught charge.
* 
False Promise can interrupt Primal Beast's Pulverize, as well as further delay Primal Beast from dealing lethal burst damage. In combination with Fortune's End, Oracle can potentially save an ally from Primal Beast's spell combos.
Broodmother
* Oracle cannot easily deal with swarms of units, making him weak against heroes like Phantom Lancer or Broodmother.
Broodmother
* Berserker's Call can catch Broodmother in her web, as well as groups of spiderlings. This is particularly effective when Broodmother attempts to push towers with her spiderlings.
* Counter Helix destroys spiderlings very quickly and earns Axe a good deal of gold.
Additional:
* 
Berserker's Call forces Broodmother and her spiderlings to attack, allowing for large amounts of pure damage to be done through 
Counter Helix.
Primal Beast
* Long lockdown is a great way to deal with Axe to prevent Berserker's Call from being used, heroes such as Legion Commander, 
Beastmaster and 
Primal Beast are good examples of this.
Additional:
* Berserker's Call will be a stun for Primal Beast and not much else due to Trample making him unable to attack.
* 
Battle Hunger is neglitable because Primal Beast has a much bigger health than Axe, so he does not need to fear being slowed, or his other abilities including Counter Helix or even a Blade Mail.
* Getting Primal Beast low enough to use a successful 
Culling Blade can be very difficult due to his massive health advantage over most heroes.
* Not ability related but Primal Beast does not need to fear Axe in lane, as Trample, combined with Uproar and Onslaught will do a ton of damage even if Axe has a 
Vanguard.
Broodmother
* Illuminate wipes out Broodmother's spiders and prevents her from pushing the lane. It also gives vision to reveal where broodmother is hiding in the trees.
Primal Beast
* Any hero who lanes very poorly will struggle with Primal Beast's potential snowball in the very early levels, like 
Keeper of the Light, Luna, 
Templar Assassin...
Primal Beast
* 
Power Cogs keeps Primal Beast pinned down, preventing him from doing damage with Trample. Primal Beast's slow attack speed makes it hard for him to break the cogs and get away. In addition, Power Cogs' knockback is forced movement and thus will intercept Primal Beast's Onslaught if placed well.
* 
Battery Assault on a lone Primal Beast in the early game effectively keeps him from winding up Onslaught or basic attacking.
* 
Rocket Flare and 
Jetpack (from purchasing Aghanim's Shard) give Clockwerk many options to scout for Primal Beast, whose kit benefits greatly from ambushing.
Broodmother
* Clockwerk lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Clockwerk finishes his initiation. Additionally, Clockwerk hates buying 
Dagon and 
Ethereal Blade, which are the only itmes that can help him deal with heroes who can recover themselves and turn the fight around to their advantage: 
Faceless Void, 
Terrorblade, 
Ursa, Weaver, Broodmother, 
Slark, Abaddon, 
Wraith King, 
Lifestealer.
Broodmother
* Sniper is completely helpless against Broodmother's abilities, and can be seriously damaged by Spiderlings in lane, especially when 
Shrapnel is on cooldown.
Primal Beast
* Primal Beast is one of Sniper's greatest counters, as he has no real means of escape and is very squishy, especially in the early game. Sniper's potshots and Shrapnel can contribute to Primal Beast's Uproar and further make him tankier than he already is. Onslaught allows him to close the gap on Sniper at his own volition, and Trample can deal serious damage to his meager health pool. Should Sniper acquire an item of escape, Primal Beast can still delay him with Pulverize. Overall, Sniper is an ideal target for Primal Beast to constantly threaten in all stages of the game, and it can force Sniper to itemize for him.
Broodmother
* Phantom Assassin's single target abilities make her very helpless against swarms of Spiderlings without Battle Fury.
* Because Phantom Assassin is always reliant on critical strikes, Broodmother will usually have enough time to use Spin Web to save herself.
* Silken Bola can cripple Phantom Assassin greatly due to her being 100% reliant on physical attacks.
Additional:
* Phantom Assassin's single target abilities make her very helpless against swarms of Spiderlings without Battle Fury.
* Because Phantom Assassin is always reliant on critical strikes, Broodmother will usually have enough time to use Spin Web to save herself.
* Silken Bola can cripple Phantom Assassin greatly due to her being 100% reliant on physical attacks.
Primal Beast
* Phantom Assassin is known to be weak against bursts of magical damage, something Primal Beast excels at from the beginning of the game. He can use this to his advantage by constantly hunting Phantom Assassin down, especially if she is left alone to farm.
* Primal Beast is a good carrier of Ethereal Blade, Vanguard and 
Shiva's Guard all of which are very good against 
Coup de Grace and 
Phantom Strike.
* Even though Primal Beast does a lot of physical damage early on, later once 
Blur becomes more potent, she may find herself being overwhelmed by Trample and Pulverize instead.
* Primal Beast also has a level 25 talent which makes Pulverize go through spell immunity which is especially effective against a hero like Phantom Assassin who relies on it.
Broodmother
* Webbed areas can be used to hit and run, covering distance hastily weakening her on the way and initiating ganks.
* Even though Medusa can hunt down Spiderlings easily when given enough range, Silken Bola will cause her attacks to miss and get her swarmed in no time.
* Medusa usually does not build a Black King Bar to benefit from 
Mana Shield fully while Broodmother can fit a 
Diffusal Blade to burn away all of Medusa's mana.
Additional:
* Spin Web will allow Broodmother to pick her own fights and sometimes slip away to ambush Medusa.
* Though Medusa's Split Shot and Mystic Snake can help Medusa deal with Broodmother's spiderlings, Broodmother will create too much of them for her to handle, allowing her to outnumber Medusa's targets from Split Shot and shield her team in process.
Primal Beast
* Hard carries who just want to farm and be left alone will not appreciate Primal Beast, heroes such as 
Medusa, 
Drow Ranger...
Broodmother
* Drow Ranger's lack of mobility makes her easy prey for Broodmother and her Spiderlings.
Primal Beast
* Heroes who have low or high armor but very high health will be difficult for drow to burst down quickly: Primal Beast, 
Axe, 
Centaur Warrunner.
Broodmother
* Broodmother relies less on abilities and more on right-clicks.
* Spiderlings can overwhelm Silencer, who has mediocre armor and no escape tool.
Primal Beast
* Any hero with low mobility and max healthsuch as 
Silencer, 
Crystal Maiden etc.
Broodmother
* 
Sprout cannot protect Nature's Prophet if Broodmother puts down a web.
* Nature's Prophet's low mobility means he is defenseless against Silken Bola.
* Spiderlings can absorb much of the damage from 
Wrath of Nature.
Additional:
* Broodmother can destroy Nature's Prophet's Treants with 
Spawn Spiderlings and summon spiderlings in their place.
* Broodmother loves buying Orchid Malevolence, which can prevent Nature's Prophet from escaping with Sprout and Teleportation.
Primal Beast
* Heroes with unorthodox escapes will struggle against Primal Beast, such as Nature's Prophet, 
Tinker, and Templar Assassin.
Broodmother
* Heroes who can summon illusions and summons because Terrorblade has no abilities to deal with multiple enemies at once outside Reflection: Shadow Shaman, Naga Siren, Broodmother, 
Lycan, Enigma, Chaos Knight, Phantom Lancer, Shadow Demon, 
Dark Seer, Nature's Prophet, 
Invoker, 
Morphling, 
Visage, Grimstroke with 
Aghanim's Scepter.
Primal Beast
* Illusion heroes will struggle against Primal Beast's area damage capability, such as Chaos Knight, Naga Siren, Terrorblade.
Broodmother
* Heroes with summons: Lycan, Broodmother, Visage, Nature's Prophet, 
Warlock.
Primal Beast
* Special mention to Lifestealer who can use 
Rage to prevent Trample damage, but Pulverize can still stun and do damage.
Broodmother
* Heroes with plenty of summons, such as Broodmother or Nature's Prophet can have their minions soak up most of your Paralyzing Cask.
Primal Beast
* Heroes who cannot escape from Trample early might be easy first blood. Heroes like 
Witch Doctor and 
Omniknight should play very cautiously alone...
Broodmother
* Illusion-based and multi-unit heroes can take advantage of Chaos Knight's lack of area damage: Naga Siren, Phantom Lancer, Broodmother
Primal Beast
* Illusion heroes will struggle against Primal Beast's area damage capability, such as Chaos Knight, Naga Siren, Terrorblade.
Broodmother
* Enchantress's lack of AoE abilities allows Broodmother to swarm her with Spiderlings.
* Spawn Spiderlings can kill enchanted creeps.
* However, keep in mind that 
Untouchable makes it harder for Brood to actually hit Enchantress, even if Broodmother is spell immune.
Additional:
* Enchantress can be easily overwhelmed with Broodmother's spiderlings from Spawn Spiderlings and Enchantress can only control one of them with 
Enchant and she has no good waveclear (Spawn Spiderlings can also kill creeps controlled with Enchant).
* However, Untouchable's attack speed reduction can make it difficult for Broodmother to kill Enchantress even with any form of spell immunity.
Primal Beast
* Morphling relies on 
Attribute Shift (Agility Gain) to take last-hits. Primal Beast's burst damage ability can constantly threaten Morphling, especially due to his short attack range. If forced to escape with 
Waveform, Primal Beast can catch up with Onslaught.
Primal Beast
* Magnus is not tanky and struggles against burst damage, something Primal Beast excels at in the early-to-mid game. Primal Beast is also able to out-damage Magnus's 
Empower and can even contribute to his Uproar stacks.
* Using 
Skewer to drag Primal Beast while he is trampling will count as movement and will trigger a rapid number of slams, which could prove lethal to Magnus.
Broodmother
* Though Mirana can clear waves of Broodmother's spiderlings with 
Starstorm, Broodmother will often stick with her spiderlings from Spawn Spiderlings, which in combination with the huge speed provided by Spin Web can make it hard for Mirana to hit her with 
Sacred Arrow.
* Broodmother commonly buys Orchid Malevolence and it's upgrade 
Bloodthorn, which allows her to prevent Mirana from escaping with both, 
Leap and 
Moonlight Shadow and from fighting back with Starstorm.
Additional:
* Though Mirana can clear waves of Broodmother's spiderlings with Starstorm, Broodmother will often stick with her spiderlings from Spawn Spiderlings, which in combination with the huge speed provided by Spin Web can make it hard for Mirana to hit her with Sacred Arrow.
* Broodmother commonly buys Orchid Malevolence and it's upgrade Bloodthorn, which allows her to prevent Mirana from escaping with both, Leap and Moonlight Shadow and from fighting back with Starstorm.
Primal Beast
* Primal Beast can use Uproar to tank a portion of 
Omnislash, giving him an edge in surviving it. Primal Beast can also dash away after Omnislash with Onslaught, disallowing Juggernaut from any follow-ups.
* 
Blade Fury will never do more damage than Uproar once the stacks are activated.
* Primal Beast is very commonly buying items that are good against Juggernaut, such as Ethereal Blade and 
Heart of Tarrasque.
* Pulverize goes through Blade Fury, making him one of the few heroes who can stop Juggernaut from spinning and teleporting to safety.
Primal Beast
* Onslaught prevents all of Razor's abilities from being effective against him, especially in the laning stage.
Primal Beast
* Trample and Pulverize can be used to cancel 
Life Drain very quickly.
* Pugna has a very low strength gain and as a support does not have much gold to buy health items, making him vulnerable to Primal Beast's onslaught of magical damage.
* Ironically, 
Decrepify actually just increases Primal Beast's damage on the targeted ally if Trample is activated. However, it can be used to slow him down and prevent any further Trample damage.
Primal Beast
* 
Dark Pact, 
Shadow Dance and 
Depth Shroud will do nothing against Onslaught and Trample, as they are both ground area-of-effect spells.
* Primal Beast has a gigantic hitbox, which could be difficult for Slark to escape with 
Pounce should Primal Beast choose to block him. Pounce also does not completely prevent Primal Beast from trampling offensively, as he still has some room to move.
* Primal Beast has a huge health pool; shedding it with 
Essence Shift can take time and may allow Primal Beast to build Uproar against him. Should he survive Slark's slew of skills, Primal Beast can simply Pulverize him to finish him off.
Broodmother
* Bounty Hunter's single-targeted arsenal of abilities make him an easy target for Broodmother and her Spiderlings.
* Broodmother often buys Orchid Malevolence and it's upgrade Bloodthorn, which allows her to stop Bounty Hunter from escaping with Shadow Walk.
Additional:
* Like with Bane, Bounty Hunter's single-targeted arsenal of abilities make him an easy target for Broodmother and her Spiderlings.
* Broodmother often buys Orchid Malevolence and it's upgrade Bloodthorn, which allows her to stop Bounty Hunter from escaping with 
Shadow Walk.
Broodmother
* Bane's single-targeted arsenal of abilities make him an easy target for Broodmother and her Spiderlings.
* Broodmother often buys Orchid Malevolence and it's upgrade Bloodthorn, which allows her to cancel 
Fiend's Grip, and completely shut Bane down.
Additional:
* Bane's single-targeted arsenal of abilities make him an easy target for Broodmother and her Spiderlings.
* Broodmother often buys Orchid Malevolence and it's upgrade Bloodthorn, which allows her to cancel Fiend's Grip, and completely shut Bane down.
Broodmother
* Viper's lack of escape and durability means he can be ran over in a laning stage by Spawn Spiderlings.
* Broodmother can bring Viper down quickly with Insatiable Hunger activated.
Primal Beast
* 
Dispersion reduces damage based on a percentage, which is very minimal against large amounts of small instances of damage such as Trample. It reduces each tick by about 14 at the maximum level, which is very small.
* 
Desolate is never a threat to Primal Beast due to his large health pool and Uproar is still out-damaging the ability.
* Onslaught can allow Primal Beast to chase Spectre fleeing with 
Spectral Dagger, as both skills phase through trees and terrain.
* Primal Beast can be strong enough to force a farming Spectre to flee with 
Haunt, putting it on a long cooldown and potentially leading her to an ally that can finish her off.
* Primal Beast excels at early aggression, pushing weak carries out of lane and farming areas he wants to control. Overall just not a pleasant matchup for Spectre.
Broodmother
* Broodmother can easily clear Wraith King's skeletons with Spawn Spiderlings and summon spiderlings in their place.
* With Diffusal Blade, Broodmother can prevent Wraith King from reincarnating unless Wraith King has his Aghanim's Shard.
Broodmother
* None of Arc Warden's abilities are very effective against Broodmother and her spiderlings.
* A good Broodmother looks to end the match early while Arc Warden, a very item reliant hero, thrives in longer matches.
* Arc Warden has no innate disables to stop Broodmother from lifestealing with Insatiable Hunger and shredding through his relatively lower armor.
Broodmother
* Chen's low mobility and lack of AoE abilities makes him an easy target for Broodmother and her Spiderlings.
* Broodmother can easily pick off Chen's creeps with Spawn Spiderlings, and by ambushing them through terrain in her web.
Additional:
* Chen has no area-of-effect spells to deal with Broodmother's spiderlings and must rely on his creeps to take care of them.
* Spawn Spiderlings can kill Chen's creeps and spawn spiderlings in their place.
* Spin Web allows Broodmother to disrupt Chen's jungling.
* Silken Bola will cause Chen and his creeps's attack to miss more often while also making them more vulnerable to magical damage, especially if Broodmother picks 400 AoE Silken Bola talent.
* Broodmother is a natural Bloodthorn wielder, which will allow her to prevent Chen from trying to save himself with 
Hand of God while also making him more vulnerable to damage, and when combined with Insatiable Hunger, it will spell a quick and certain death for Chen. Bloodthorn's passive ability will also reduce any spell damage Chen tries to inflict with his creeps.
* 
Spinner's Snare from Aghanim's Scepter allows Broodmother to create invisible lines on her webs from Spin Web that will root Chen and his creeps, deal damage over time to them and reveal them if they unwittingly steps on them, disrupting Chen's jungling even more while also alerting Broodmother on their attempts to ambush her and her allies.
Broodmother
* Spiderlings melt away 
Living Armor almost instantly.
* The vision from 
Eyes In The Forest may prove dangerous for Broodmother, however.
Broodmother
* 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.
Broodmother
* Heroes with summons like Broodmother, Enigma, Nature's Prophet; or illusions, like Naga Siren, Terrorblade are effective at keeping the choke points and rune spawns safe from Proximity Mines.
Broodmother
* Heroes with blind of some sort can be a bad choice for Monkey King to go on: Broodmother, 
Riki, Keeper of the Light.
Primal Beast
* Any hero with low mobility and max healthsuch as Silencer, Crystal Maiden etc.
Primal Beast
* Any hero who lanes very poorly will struggle with Primal Beast's potential snowball in the very early levels, like Keeper of the Light, Luna, Templar Assassin...
Primal Beast
* Third and final special mention to Ursa who can resist Trample damage with 
Enrage but Pulverize will still stun for the full duration.
Primal Beast
* Any hero who lanes very poorly will struggle with Primal Beast's potential snowball in the very early levels, like Keeper of the Light, Luna, Templar Assassin...
Broodmother
* Charge of Darkness provides shared vision over its target, keeping track of heroes who rely on invisibility, mobility, or illusions: Riki, Broodmother, Phantom Lancer
Broodmother
* 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.
Primal Beast
* Durable heroes: Axe, 
Bristleback, 
Tidehunter, Wraith King, Primal Beast, 
Underlord.
Primal Beast
* Heroes who cannot escape from Trample early might be easy first blood. Heroes like Witch Doctor and Omniknight should play very cautiously alone...
Broodmother
* 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.
Primal Beast
* Illusion heroes will struggle against Primal Beast's area damage capability, such as Chaos Knight, Naga Siren, Terrorblade.
Primal Beast
* Heroes with unorthodox escapes will struggle against Primal Beast, such as Nature's Prophet, Tinker, and Templar Assassin.
Broodmother
* Heroes with illusions and summons can manfight Night Stalker: Terrorblade, Beastmaster, Broodmother.
Broodmother
* Heroes with very little to no area-of-effect abilities will struggle greatly against Broodmother: Sniper, Phantom Assassin, Nyx Assassin, 
Bane, Visage, 
Bounty Hunter.
Primal Beast
* 
Malefice will prevent Primal Beast from doing anything for a long duration even in the early game when at his strongest.
* 
Midnight Pulse will scale with his max health so will do a ton of damage combined with any generic stun or Enigma's own abilities.
* Primal Beast relies completely on mobility to do damage, 
Black Hole makes sure he cannot use any abilities or threaten heroes he is typically good against.
Broodmother
* Broodmother can kill Enigma's Eidolons with Spawn Spiderlings, and spawn her spiderlings in their place. But remember that Enigma can do the same to Broodmother's spiderlings with 
Demonic Conversion and Midnight Pulse.
* Without the protection from Black King Bar, Broodmother can cancel Enigma's Black Hole with Bloodthorn and make him more vulnerable to damage. Broodmother can also buy 
Abyssal Blade to cancel Enigma's Black Hole even through Black King Bar.
* Silken Bola causes Enigma's attacks to miss a lot and renders him more vulnerable to magical damage. And if Broodmother takes 400 AoE Silken Bola, then she will be able to use to cause Enigma's Eidolons to miss their attacks as well. In addition, Enigma does not like to buy items to provide him true strike such as Bloodthorn, 
Monkey King Bar, 
Witch Blade and it's upgrade Revenant's Brooch.
* If Broodmother is lucky enough to survive being trapped in Black Hole, she will be able to recover her lost health with Insatiable Hunger.
* Aghanim's Scepter gives Broodmother access to Spinner's Snare, which allows her to create invisible lines on her webs from Spin Web that will root Enigma, deal damage over time to Enigma and reveal Enigma if he unwittingly steps on them, disrupting his attempts to initiate with Black Hole, prevent him from using Blink Dagger, while also alerting Broodmother on his attempts to ambush her and her allies.

Primal Beast
* 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.
Broodmother
* 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.
Primal Beast
* 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.
Broodmother
* 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.
Broodmother
* 
Ice Blast prevents Insatiable Hunger lifesteal, Spin Web regeneration and quickly kills spiderlings.
Primal Beast
* Since Primal Beast is highly mobile with Onslaught alone, he will be difficult to catch with both 
Cold Feet and Ice Blast.
* Ice Blast is less effective due to Primal Beast's massive health pool and resistance to taking damage.
* While 
Chilling Touch can be used to slow Primal Beast briefly, it is not enough to beat him back, and can also contribute to his Uproar stacks.
* Primal Beast has a dispel talent at level 15 that will remove Cold Feet immediately when Uproar is used.
Primal Beast
* Like above, supports with reliable stuns can be a massive problem and force Black King Bar in fights unideally, such as Shadow Shaman, Lion, Nyx Assassin.
Broodmother
* 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.

Primal Beast
* Invoker's numerous area-of-effect abilities can interrupt Primal Beast, especially while he is in the middle of a team fight, where Primal Beast thrives. (
Tornado, 
Cold Snap, and 
Ice Wall all help to disable Primal Beast and control him from a distance.
* 
E.M.P. disintegrates Primal Beast's low mana pool.
* However, Invoker is quite a slow-paced hero and not particularly known for being survivable against a rampaging Primal Beast with Black King Bar.
Broodmother
* Broodmother can kill Invoker easily in the early game with her Spawn Spiderlings and her spiderlings.
* Broodmother is both an Orchid Malevolence and a Nullifier carrier. As she can farm it early, she can kill Invoker easily.
Broodmother
*
Great Cleave cleans up Spiderlings quicker than most spells, as it ignores their magic resistance.
Black King Bar carrier, protecting him from Silken Bola, Spawn Spiderlings and 
Orchid Malevolence.
Warcry and 
God's Strength allow Sven to easily out-damage Broodmother.
* Sven is a natural
*
Additional:
* Great Cleave clears Spiderlings quickly to increase gold income.
* Warcry shields Sven and his allies against Broodmother and her Spiderlings.
Primal Beast
*
Storm Hammer will allow Sven to run away in the laning stage very easily or turn the tide of the fight.
Warcry can be used to outrun Primal Beast, or in response to his Uproar damage boost.
God's Strength will make sure work of Primal Beast if caught alone due to his low armor.
