* Beastmaster's Hawk can find Monkey King easily while he is sitting on tree.
* Beastmaster's Wild Axes can knock out Monkey King from tree.
* Beastmaster's Boars drastically reduce Monkey King's attack speed, making it harder for him to gain Jingu Mastery stacks.
Additional:
* Wild Axes can chop down trees, making it difficult for Monkey King to utilize Tree Dance well.
* Call of the Wild Hawk can scout Monkey King when he is perched on top of trees.

* Charge of Darkness keeps vision of Monkey King, even when he is in the trees.
* Nether Strike locks onto Monkey King and focuses damage on him during Wukong's Command.

* Beastmaster's Hawk can find Tinker easily while he is pushing or blinking into trees.

* Tinker relies on his high mobility from Boots of Travel and Blink Dagger to survive. Those items don't help him if Spirit Breaker manages to cast Charge of Darkness on him.
* Spirit Breaker can easily cancel Rearm and Boots of Travel.

* Attacks from Boars and Inner Beast will quickly wear down Refraction.
* True Sight provided by Level 3 Necronomicon can see Templar Assassin in Meld.

* Because Templar Assassin does not have escape potential in lane, any support hero with roaming potential and a Dust of Appearance can be great at shutting her down early game: Earth Spirit, Spirit Breaker, Tusk, Bounty Hunter, Riki, Warlock.

* Magic Missile has a considerably long cast time, making it difficult to stop Charge of Darkness with it.
* Other than Magic Missile, Vengeful Spirit has no way of canceling Nether Strike.

* Heroes who relies on illusions and summons (Beastmaster, Chaos Knight, etc.).

* Heroes with disables that ignore spell immunity will render Phantom Assassin quite useless in teamfights throughout the game: Enigma, Vengeful Spirit, Doom, Bane, Beastmaster, Pudge.

* Heroes that rely on escapes to stay alive can be caught and locked down for a long time: Queen of Pain, Phantom Assassin

* Spirit Breaker can chase Nature's Prophet from anywhere on the map with Charge of Darkness, making it hard for Nature's Prophet to split-push.
* Charge of Darkness and Nether Strike gives vision of Nature's Prophet when he tries to Sprout himself and teleport away.
Additional:
* Charge of Darkness allows Spirit Breaker to catch Nature's Prophet out when he tries to split push.
* Nature's Prophet can't hide in his Sprout against Spirit Breaker, as his Charge of Darkness provides vision on its target.
* Spirit Breaker can easily cancel Nature's Prophet's Teleportation.

* Charge of Darkness can be used to escape or counter-initiate against a Relocate gank.
* Greater Bash and Nether Strike is devastating due to Io's low armor, and can even knock it away from tethered target.

* Spirit Breaker can charge towards Sniper from anywhere on the map with Charge of Darkness.
* Greater Bash deals magical damage, which can prove dangerous to Sniper and his low health.
* Both previous abilities combined with Nether Strike ensures that Spirit Breaker can easily solo kill Sniper.

* Primal Roar pierces Rage and can disable Lifestealer in fights.

* Primal Roar and the slow from Boars makes kiting Tiny very easy.

* Primal Roar and the slow from Boars makes kiting Ursa very easy.

* Call of the Wild Hawk can scout Techies as they are placing mines.
* Call of the Wild Boar can clear Proximity Mines.
* The stun of Primal Roar will usually be enough to deal with the squishy Techies before they can try to suicide with Blast Off!.

* Charge of Darkness can be used to chase down Pangolier if he escapes with Swashbuckle or Rolling Thunder.
* Nether Strike ignores Rolling Thunder's spell immunity, and will still hit Pangolier if he rolls or dashes away.

* Heroes with other kind of disables that pierce spell immunity can hold Pangolier in place during Rolling Thunder: Axe, Beastmaster, Enigma, Magnus, Pudge, Batrider, Bane, Winter Wyvern

* Charge of Darkness allows Spirit Breaker to gank Shadow Fiend in the early game, preventing him from getting Necromastery stacks.
* Nether Strike and Charge of Darkness can be used to prevent Shadow Fiend from casting Requiem of Souls.

* Primal Roar and the slow from Boars makes kiting Troll Warlord very easy.

* Spirit Breaker's Charge of Darkness semi-reveals Bounty Hunter, taking away his element of surprise for the duration of the charge. Also, as Charge of Darkness shows Bounty Hunter's position, Spirit Breaker's allies can proceed to gank Bounty Hunter while he is roaming alone.

* Primal Roar allows Beastmaster to keep Lycan in place after he used his Shapeshift.

* Primal Roar takes Sven out of the fight completely, even with Black King Bar.

* Anti-Mage usually relies on Blink to escape, but with vision from Charge of Darkness it is easier to catch him.
* Spirit Breaker could single-handedly lock Anti-Mage down for 4 seconds (or even more with lucky bashes), allowing his teammates to follow up.
* As Anti-Mage is an elusive hero who likes to farm alone, Spirit Breaker could choose to charge whenever Anti-Mage is in sight.

* Possibly Clinkz's worst enemy. He has many tools to utterly destroy Clinkz.
* Charge of Darkness can be used on Clinkz if Spirit Breaker's team spots him anywhere. This charge will track his location through Skeleton Walk's invisibility and movement speed bonuses.
* When Spirit Breaker charges onto Clinkz, he can easily use Dust of Appearance to guarantee a reveal on him while stunned.
* All three of Spirit Breaker's spells help him and his team quickly close the gap to Clinkz even at the edge of his attack range or when running away with Skeleton Walk.
* Spirit Breaker's high strength and above average armor makes him able to endure Clinkz's onslaught, meanwhile Clinkz will be heavily threatened if Spirit Breaker procs a Greater Bash.
Additional:
* Once caught with dust, Clinkz could be locked down for a long time by Spirit Breaker and has nowhere to escape.
* Charge of Darkness provides shared vision over its target, showing Clinkz even when he is in Skeleton Walk.

* Bristleback, Centaur Warrunner, Spirit Breaker, Pudge, Huskar: These heroes are too tanky for Puck to burst down. Also, all of them have spells which can deal with and shut Puck down reliably.

* Heroes with long-lasting, undispellable debuffs will pinpoint the true Naga Siren: Spirit Breaker, Bloodseeker.

* Heroes with mobility/escape mechanisms to dodge Ancient Apparition abilites, or to easily jump on him: Riki, Queen of Pain, Phantom Assassin, Windranger, Bounty Hunter, Spirit Breaker, Night Stalker, Storm Spirit, Juggernaut, etc.

* Skywrath mage also has a terrible time fighting against anything that isn't a hero. As Mystic Flare only affects heroes, his skills are mostly target-based and he has terrible strength and agility, he can easily be kited or harassed by illusion-based heroes like Chaos Knight and Phantom Lancer, or by Heroes that summon other units like Lone Druid, Lycan and Beastmaster.

* Spirit Breaker's stuns pierce spell immunity, making him a good choice against heroes that heavily rely on Black King Bar; Huskar

* Warlock is a very strong hero when positioned correctly, and his long cast range helps him with this. However, some Heroes might disrupt or sneakily pass through your allies and deal with you, preventing you from doing your job. Such heroes include Chaos Knight, Spirit Breaker, Riki, and some others.

* Heroes that rely on invisibility can be tracked with Charge of Darkness opening them to team attacks: Bounty Hunter, Mirana, Riki

* Mana Break can deplete Wraith King's mana and prevent him from using Reincarnation.
* Wraith King's lack of area effect spell makes him easily overwhelmed by Beastmaster's summons.

* Because only one clone needs to be killed in order to kill Meepo, heroes that excel at singling out enemies can also be a detriment to him, such as Batrider, Beastmaster, Pudge and Clockwerk.

* Heroes who can stun multiple units at once: Dark Willow, Spirit Breaker, Slardar, Invoker, and Tidehunter.

* Inner Beast helps Beastmaster's team destroy Supernova quickly.

* Illusion or summon-based heroes can be a problem to Viper due to his lack of AoE damage: Naga Siren, Phantom Lancer, Beastmaster

* Heroes with illusions and summons can manfight Night Stalker: Terrorblade, Beastmaster, Broodmother.
