Spirit Breaker
* 
Astral Imprisonment can be used to protect allies by imprisoning either them or Spirit Breaker.
* 
Arcane Orb will heavily drain Spirit Breaker's maximum mana, rendering him almost useless and unable to cast spells. And considering how Spirit Breaker's intelligence is very low, 
Sanity's Eclipse will deal a lot of damage to him.
* Even if Spirit Breaker survives Sanity's Eclipse, mana allergy applied by the Sanity's Eclipse will discourage Spirit Breaker from using his abilities as it will cause him to lose health and heal Outworld Destroyer.
Lone Druid
* Arcane Orb deals heavy damage to both Lone Druid and the Spirit Bear.
* Astral Imprisonment can prevent the Spirit Bear from attacking, which is Lone Druid's main damage output.
* Sanity's Eclipse deals heavy damage to Lone Druid.
Spirit Breaker
* Due to Spirit Breaker's low attack speed, 
Supernova is problematic for Spirit Breaker to take down, and even more so with 
Fire Spirits debuff applied.
Lone Druid
* Lone druid's bear attacks on Phoenix's Supernova Egg don't increase the hit count. Given that Lone Druid's main hero often doesn't have much farm, the Supernova Egg is less likely to get killed.
Spirit Breaker
* 
Nature's Grasp severely slows down Spirit Breaker, reducing effects of Charge of Darkness and Greater Bash.
* 
Living Armor can mitigate a large portion of Spirit Breaker's damage since his attacks are slow.
* Treant Protector can also counter-initiate against Spirit Breaker with 
Leech Seed, 
Overgrowth and with his root from 
Aghanim's Shard upgraded 
Nature's Guise before he manages to escape.
* 
Aghanim's Scepter gives Treant Protector access to 
Eyes In The Forest ability, which allows him to turn trees into wards that provide vision, allowing him to keep his allies warned about Spirit Breaker's attempts to gank them. Eyes In The Forest will also trigger Overgrowth if Spirit Breaker is in range of the tree affected by it.
Additional:
* Spirit Breaker's slow attacks cannot harm a hero shielded by Living Armor.
Lone Druid
* 
Clinkz, 
Sniper, 
Lone Druid, 
Troll Warlord, 
Legion Commander and 
Wraith King are some of the Heroes that base themselves on attacks with little or no spell power, so they suffer in the grassy hands of Overgrowth.
Spirit Breaker
* 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, Wraith King.
Lone Druid
* Reality Rift lets Chaos Knight bypass the Spirit Bear and jump onto Lone Druid.
* The Spirit Bear's lack of scaling means it dies quickly to Chaos Knight during the late-game.
Spirit Breaker
* Heroes that can slow Charge of Darkness by a huge amount: 
Venomancer, 
Viper, 
Dazzle, 
Arc Warden, 
Lion, 
Huskar, Shadow Shaman, Visage, 
Undying, 
Jakiro.
Lone Druid
* Dazzle easily breaks the position of Lone Druid and his 
Summon Spirit Bear with his 
Poison Touch, As it always hits from afar and prolongs the slowdown on the Summon Spirit Bear, which is why he cannot catch up with Dazzle and treat his master with 
Spirit Link
* Dazzle helps his team survive the physical attacks of the Summon Spirit Bear thanks to the treatment from 
Shadow Wave and armor from 
Bad Juju, which can enable his team to kill Lone Druid
* The Lone Druid Summon Spirit Bear has a small amount of armor at the start of the game, because of Mid Dazzle, it can very much break through it and prevent Lone Druid from gaining an advantage at the very beginning of the game, giving his team the opportunity to overtake Lone Druid on items for killing him, by type: 
Spirit Vessel

Spirit Breaker
* 
Morph allows Morphling to copy abilities of Spirit Breaker and combine them with 
Waveform to turn things around. Aghanim's Scepter upgraded Morph also allows Morphling to create a strong illusion of Spirit Breaker that can cast all of his basic abilities. This allows Morphling to give Spirit Breaker a taste of his own medicine.
* Spirit Breaker's low attack speed and lack of burst damage makes it unlikely for him to win against Morphling when he has 
Attribute Shift (Strength Gain) toggled on.
Lone Druid
* Morphling can ignore Spirit Bear and shorten the distance to Lone Druid with Waveform.
* Morphling can use his nukes to burst Lone Druid down, provided he is not rooted/disabled by Spirit Bear beforehand.
Lone Druid
* Heroes who just want to farm and avoid Lone Druid early will find it very hard to do so when he starts knocking on towers: 
Templar Assassin, 
Phantom Assassin, 
Ember Spirit, 
Morphling.
Spirit Breaker
* In the early game, Omniknight can look like an easy target for Spirit Breaker, but with 
Purification and 
Hammer of Purity, what could be an opportunity could quickly turn into disaster.
* 
Repel can be used to counter Charge of Darkness by minimizing the damage and lowering the stun duration with status resistance.
* Spirit Breaker's Greater Bash from all sources (Charge of Darkness or normal attacks) will deal no damage at all if Omniknight and his allies are protected with presence.
* Due to this, Spirit Breaker's damage will always be lower when targeting Omniknight.
Spirit Breaker
* If Medusa activates 
Stone Gaze before Spirit Breaker reaches her with Charge of Darkness, the charge will inevitably fail.
* Medusa has three ways to counter Spirit Breaker's Charge of Darkness: Stone Gaze can disable Spirit Breaker's Charge of Darkness if he faces Medusa directly. Aghanim's Scepter upgraded 
Mystic Snake can disable Spirit Breaker and cancel his Charge of Darkness if it hits him. And 
Cold Blooded provided by Aghanim's Shard that can cast a single-targeted Mystic Snake at Spirit Breaker if he uses Charge of Darkness on her.
* 
Mana Shield and overall tankiness allows Medusa to easily survive Spirit Breaker's initiation. And to make things worse, Spirit Breaker is not a common 
Diffusal Blade nor 
Disperser wielder to counter this problem at all.
* Overall, any attempt for Spirit Breaker to gank and kill Medusa will hurt him more than the other way around.
Lone Druid
* 
Cold Embrace can protect allies from Lone Druid and the Spirit bear, who mainly deal physical damage
* 
Winter's Curse can turn Lone Druid and the Spirit Bear against his teammates.
Lone Druid
* 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.
Spirit Breaker
* Due to Spirit Breaker's low attack speed, 
Tombstone is problematic for Spirit Breaker as the zombies summoned from Tombstone apply a stacking movement speed slow, which can significantly reduce Greater Bash's damage.
* 
Soul Rip and 
Decay allows Undying and his allies to survive and recover from any incoming ganks by Spirit Breaker.
Spirit Breaker
* 
Malefice prevents Spirit Breaker from using his spells for the duration.
* Eidolons from 
Demonic Summoning have high magic resistance, receiving little damage from Charge of Darkness and Greater Bash.
* 
Midnight Pulse can deal big damage to Spirit Breaker, as it deals damage based on enemy hero's max health.
* 
Black Hole makes it very dangerous for Spirit Breaker to reach Enigma with Charge of Darkness unless if he has Nether Strike available to use.

* Black Hole makes it very dangerous for Spirit Breaker to reach Enigma with Charge of Darkness unless if he has Nether Strike available to use.
Spirit Breaker
* Clockwerk can use Power Cogs to repel Spirit Breaker when he charges in with 
Charge of Darkness.
* Spirit Breaker's slow 0.6 second attack animation attacks do little damage against Clockwerk. It can also constantly be interrupted by Battery Assault.
* 
Nether Strike's 1.2 second charge time gives Clockwerk plenty of time to activate 
Blade Mail and for Battery Assault to cancel it.
Additional:
* 
Battery Assault will continuously prevent Spirit Breaker from using Nether Strike, Charge of Darkness and even right clicking because of his slow base attack speed.
Spirit Breaker
* Fissure interrupts Spirit Breaker during Charge of Darkness.
Spirit Breaker
* Bramble Maze stops Charge of Darkness in its tracks. Its very long duration means it can be used as an obstacle to block off an incoming Spirit Break during teamfights.
* Shadow Realm and Bedlam can be activated when Dark Willow sees Charge of Darkness coming, preventing Spirit Breaker from using Nether Strike after the initial stun.
Lone Druid
* 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.
Lone Druid
* Paralyzing Cask is likely to bounce between him and his bear every single time.
* Lone Druid's lack of mobility makes him vulnerable to Death Ward and Maledict.
Spirit Breaker
* Nether Strike can't remove Static Link and reduces Spirit Breaker's physical damage output.
* Eye of the Storm melts Spirit Breaker's armor, and makes him much less tanky.
Additional:
* 
Plasma Field can slow Spirit Breaker and reduce damage from Greater Bash.
* 
Static Link drains damage bonus from Greater Bash, and it cannot be removed by Nether Strike.
* 
Storm Surge will proc on Spirit Breaker every time he attacks Razor or if he uses Charge of Darkness on Razor, damaging him and alerting Razor to Spirit Breaker's incoming ganks, no matter how far Spirit Breaker is from Razor.
* 
Eye of the Storm can rapidly reduce Spirit Breaker's armor, making him much less durable, especially in teamfights.
Spirit Breaker
* If Luna chooses to use 
Eclipse in anticipation right before Spirit Breaker gets to her with Charge of Darkness, she will be able to kill Spirit Breaker before he will be able to kill her as Spirit Breaker's attack speed is rather low.
* Meanwhile, when Spirit Breaker is focusing on any of Luna's allies with Charge of Darkness, Aghanim's Scepter upgraded Eclipse can be used to counter-initate against Spirit Breaker.
* Aghanim's Shard upgraded 
Moon Glaives allows Luna to reduce damage from Greater Bash and Nether Strike inflicts on her, and damage Spirit Breaker whenever he is close to her, even while he is invisible.
* 
Lucent Beam can be used to cancel Spirit Breaker's Charge of Darkness under the condition that Luna is able to cast it on time. Lucent Beam can also be used to cancel Nether Strike. But bear in mind, however, that Spirit Breaker can counter this with 
Planar Pocket from Aghanim's Shard which can be used to reflect Lucent Beam back at Luna.
* If Luna buys 
Linken's Sphere, it will become nearly impossible for Spirit Breaker to reach Luna unless some of Spirit Breaker's allies can pop it and put it on a cooldown.
* Even though Spirit Breaker can evade all of Luna's abilities with 
Shadow Blade, smart Luna will always buy 
Dust of Appearance to provide vision on Spirit Breaker to her and her team. Luna can also buy 
Gleipnir to counter Spirit Breaker's Charge of Darkness and Shadow Blade combo.
Additional:

Lone Druid
* Illusions and summons are double-edge sword type of matchup for Luna. On one hand, they can tank damage from Eclipse, but on the other hand, she can easily clear them before Eclipse with Moon Glaives. Examples include 
Spectre, 
Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, Terrorblade) or bring other units into the fight (such as Nature's Prophet, Lone Druid, 
Chen, 
Enchantress, 
Meepo and Arc Warden).
Lone Druid
* Heroes that create illusions: Spectre, Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, Terrorblade) or bring other units into the fight (such as Nature's Prophet, Lone Druid, Chen, Enchantress, Meepo and Arc Warden) can cause Eclipse to strike the illusions/summons unintentionally. However, in many cases Moon Glaives can resolve this issue and eliminate them before activating Eclipse, but that will require lots of farming for right-click items.
Lone Druid
* 
Ghost Shroud can be use both offensively to slow Lone Druid or Defensively to prevent Lone Druid and The Spirit Bear from attacking him.
* 
Heartstopper aura burns the Spirit bear High HP over time. Additionally, it can deal decent damage to Lone Druid during his True Form.
Spirit Breaker
* Rubick can cancel Spirit Breaker's Charge of Darkness with 
Telekinesis under the condition that Rubick is able to cast it on time. And considering Rubick commonly buys 
Eul's Scepter of Divinity that can also cancel Charge of Darkness, Spirit Breaker will have a hard time charging Rubick or his allies until Spirit Breaker buys Shadow Blade. Telekinesis can also be used to cancel Nether Strike and Aghanim's Shard upgraded Telekinesis also allows Rubick to save his allies from Spirit Breaker.
* 
Fade Bolt weakens Spirit Breaker's damage output, reducing damage of Greater Bash.
* If Rubick succeeds to steal Charge of Darkness, he will be able to reduce much of Spirit Breaker's global presence. Rubick can also steal Nether Strike to further disable Spirit Breaker once he disables him with stolen Charge of Darkness. But bear in mind, however, that a skilled Spirit Breaker can use Bulldoze to prevent all that.
Spirit Breaker
* Heroes that can slow Charge of Darkness by a huge amount: Venomancer, Viper, Dazzle, Arc Warden, Lion, Huskar, Shadow Shaman, Visage, Undying, Jakiro.
Lone Druid
* Huskar jumps on the hero without any problems, throwing the Summon Spirit Bear away from him and forbidding him to beat, which knocks down the regeneration of Lone Druid from the Spirit Link ability, in addition, Huskar instantly deals fatal damage to Lone Druid, in some cases he does not even have time to squeeze the 
True Form
Additional:

Spirit Breaker
* Spirit Breaker's stuns pierce spell immunity, making him a good choice against heroes that heavily rely on 
Black King Bar; Huskar
Lone Druid
* Tiny can be a serious problem for the distance between Lone Druid and his Summon Spirit Bear with his 
Toss ability, since he will throw one away from the other, giving his team the opportunity to deal with either the Summon Spirit Bear or Lone Druid himself
* Lone Druid will not always be in his True Form, since she has her own recharge, which is why Tiny can find him with a Shadow Blade or 
Blink Dagger and kill him in a second with a combination of 
Avalanche and Toss, due to the fact that Lone Druid has a very small health reserve without True Form
Additional:
* Tiny can be a serious problem for the distance between Lone Druid and his Summon Spirit Bear with his Toss ability, since he will throw one away from the other, giving his team the opportunity to deal with either the Summon Spirit Bear or Lone Druid himself

Spirit Breaker
* Spirit Breaker's slow attack speed and moderate damage do very little to harm Dragon Knight, even if ganked with Charge of Darkness.
Spirit Breaker
* Heroes who can continue dealing damage even while being stunned: 
Luna, 
Razor, 
Axe, 
Bristleback, 
Leshrac, 
Death Prophet, Jakiro.
Lone Druid
* Lone Druid and The Spirit Bear cannot burst down Bristleback due to 
Bristleback
* Bristleback can easily run to Lone Druid without any hesitation, with 
Viscous Nasal Goo to reduce armor and slow the Spirit Bear or Lone Druid and 
Quill Spray can deal damage to both Lone Druid and the Spirit Bear at the same time
Spirit Breaker
* 
Spirit Breaker's Nether Strike with Aghanim's Shard disables Bristleback's passives.
Lone Druid
* Grimstroke's 
Soulbind will always reliably connect onto both of them if they are close together.
Spirit Breaker
* 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, Wraith King.
Lone Druid
* Unless Lone Druid purchases a Black King Bar for his Spirit Bear, Ensnare will easily kite the Spirit Bear.
* Song of the Siren allows Naga Siren and her team to completely bypass the Spirit Bear and hunt for the Lone Druid himself when starting a fight.
* Lone Druid's lack of innate AoE capabilities mean that Naga Siren's illusions have no problem against him.
Spirit Breaker
* Heroes with long-lasting, undispellable debuffs will pinpoint the true Naga Siren: Spirit Breaker, 
Bloodseeker, 
Witch Doctor.
Spirit Breaker
* 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, Wraith King.
Lone Druid
* Lone Druid and his Spirit Bear lack mobility, and are easy overwhelmed after being slowed by Diffusal Blade.
* 
Savage Roar is useless since Phantom Lancer can return to fight him again with his 
Phantom Rush.
Spirit Breaker
* Charge of Darkness provides shared vision over its target, keeping track of heroes who rely on invisibility, mobility, or illusions: 
Riki, Broodmother, Phantom Lancer
Spirit Breaker
* 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, Wraith King.
Spirit Breaker

Nyx Assassin, 
Clockwerk, Spirit Breaker, 
Omniknight, 
Pudge.
Spirit Breaker
* 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, Wraith King.
Spirit Breaker
* Heroes with gap-closing abilities who attempt to use them for escaping Bloodseeker will suffer serious damage from Rupture: Phantom Assassin, 
Anti-Mage, 
Faceless Void, Riki, 
Slark, Spirit Breaker.
Spirit Breaker
* Heroes that can cancel Charge of Darkness: 
Ogre Magi, 
Earthshaker, Lion, 
Rubick, 
Lina, Luna, Jakiro, 
Dawnbreaker, 
Alchemist, Ogre Magi, Axe, Shadow Shaman, Naga Siren,

Kunkka, 
Disruptor.

Lone Druid
* 
Pugna: 
Decrepify prevent the Spirit bear from attacking or protect allies from it.
Lone Druid
* Timbersaw: Lone Druid will have a hard time dealing with Timbersaw due to his tankiness and high Armor from 
Reactive Armor
Spirit Breaker
* Heroes that punish mobile heroes: Bloodseeker, Keeper of the Light, Kunkka, Disruptor.
Spirit Breaker
* 
Mana Drain has an fair long range and low cooldown. It can easily deplete most heroes of their entire mana pools, especially those with smaller mana pools such as 
Tiny or Spirit Breaker.
Spirit Breaker
* Heroes that can slow Charge of Darkness by a huge amount: Venomancer, Viper, Dazzle, Arc Warden, Lion, Huskar, Shadow Shaman, Visage, Undying, Jakiro.
Lone Druid
* Heroes that have doubles or clones such as Arc Warden, Meepo or Lone Druid are vulnerable to Muerta's 
Gunslinger.
Spirit Breaker
* 
Earthbind's root prevents/interrupts Charge of Darkness.
* As a single-target focused hero without much damage output, Spirit Breaker is ineffective in general against Meepo.
Spirit Breaker
* Heroes who can stun multiple units at once: 
Dark Willow, Spirit Breaker, 
Slardar, 
Invoker, and Tidehunter.
Lone Druid
* 
Mystic Flare can be used to effectively ignore the Spirit Bear entirely and burst Lone Druid during the early mid game.
* 
Concussive Shot and 
Arcane Bolt will provide vision of Lone Druid allowing for better chase in teamfights before the Spirit Bear can do too much damage.
* 
Ancient Seal denies the ability to transform into True Form and receive bonus HP from the skill.
Lone Druid
* Skywrath Mage also has a terrible time fighting against anything that isn't a hero. 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
* Spirit Breaker won’t do much harm to Enchantress because of Untouchable and Nature's Attendants. Unless Enchantress is low on HP, Spirit Breaker won’t be able to catch her with mere spells.
Spirit Breaker
* Heroes with nukes that can jump her: Clockwerk, 
Snapfire, Spirit Breaker, 
Techies
Spirit Breaker
* Axe, Bristleback, 
Centaur Warrunner, Spirit Breaker, Pudge, Huskar, Wraith King, 
Doom: 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.
Lone Druid
* Lone Druid has a huge reserve of health on the Summon Spirit Bear and a quick regeneration of his health with the help of Spirit Link, which makes the Puck's magical abilities useless, since they cannot break through such a large pool of health
* The ability of the Summon Spirit Bear and in the True Form of the Lone Druid 
Entangling Claws allows you to catch Puck when he released the 
Illusory Orb, since Puck will not be able to apply 
Ethereal Jaunt during the root action
Additional:
* Lone Druid has a huge reserve of health on the Summon Spirit Bear and a quick regeneration of his health with the help of Spirit Link, which makes Puck's magical abilities almost useless, since they cannot break through such a large pool of health.
* The ability of the Summon Spirit Bear and in the True Form of the Lone Druid, Entangling Claws, allows him to catch Puck when it releases the Illusory Orb, since Puck will not be able to apply Ethereal Jaunt during the root.
Spirit Breaker
* 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, Wraith King.
Spirit Breaker
* 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.
Lone Druid
* Once caught in Bear's Entangle, Nature's Prophet cannot escape with Teleportation.
Spirit Breaker
* 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.
Lone Druid
* Heroes who just want to farm and avoid Lone Druid early will find it very hard to do so when he starts knocking on towers: Templar Assassin, Phantom Assassin, Ember Spirit, Morphling.
Spirit Breaker
* 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.
Lone Druid
* Lone Druid's early game is good against slow, squishy supports since his bear is very strong early game and an Entangling Claws proc almost always guarantees a kill: 
Ancient Apparition, 
Crystal Maiden, Shadow Shaman, etc.
Spirit Breaker
* Heroes that rely on escapes to stay alive can be caught and locked down for a long time: Queen of Pain, Phantom Assassin
Lone Druid
* Heroes who just want to farm and avoid Lone Druid early will find it very hard to do so when he starts knocking on towers: Templar Assassin, Phantom Assassin, Ember Spirit, Morphling.
Spirit Breaker
* 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.
Spirit Breaker
* 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.
Spirit Breaker
* 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.
Spirit Breaker
* 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.
Lone Druid
* Silencer's disables are useless on Lone Druid since he is more reliant on physical attacks rather than spells.
* Silencer has poor mobility so Lone Druid can run him down.
* Lone Druid's Shard will remove most of Silencer's spells once used.
Lone Druid
* 
Omnislash spreads on both the bear and the druid, allowing them to survive.With enough levels,the bear can soak the ability alone and possibly dragging him to a dangerous location.
* Juggernaut cannot manfight the duo in the early game,because of their tankiness. If opposed in lane,Lone Druid can shut him down.
Spirit Breaker
* 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 his 
Tethered target.
Spirit Breaker
* 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.
Spirit Breaker
* 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.
Spirit Breaker
* 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.
Spirit Breaker
* Heroes that can easily bypass Chen's creeps to get to Chen: Riki, Tusk, Clinkz, Sniper, Slark, Phantom Assassin, 
Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, Spirit Breaker.
Spirit Breaker
* Heroes that rely on invisibility can be tracked with Charge of Darkness opening them to team attacks: Bounty Hunter, Mirana, Riki
Spirit Breaker
* Heroes with long range abilities are also able to touch Zeus, such as Clockwerk, Kunkka, Puck, 
Skywrath Mage, Spirit Breaker, Tusk and others.
Spirit Breaker
* Generally, heroes that can close the gap on Drow Ranger to cancel her Marksmanship such as Phantom Assassin, Spirit Breaker, and Tusk are effective at limiting her power and bursting her down.
Lone Druid
* Nukers who have set amounts of damage will really struggle against Lone Druid especially in True Form: Puck, Void Spirit, Mars.
Spirit Breaker
* Windranger tends to fare badly against high mobility heroes that can easily dodge Powershot, close the gap on her when she uses Windrun or escape from Focus Fire's reach. Examples of such heroes include Spirit Breaker, Lycan, Storm Spirit, Earth Spirit, Void Spirit, Slark and others.
Lone Druid
* Heroes who can fight back easily are not ideal matchups for Sven, such as Troll Warlord as mentioned above, Lone Druid and Templar Assassin.
Lone Druid
* Besides Lone Druid and Meepo, Doom is potentially good versus every hero since Doom will render any hero helpless for up to 16 seconds. This is particularly true for fragile heroes that heavily rely on mobility to stay alive.
Lone Druid
* Lone Druid is essentially two heroes. Dooming one over the other still leaves Lone Druid or his bear able to do their job during a fight. Additionally, Lone Druid is not hindered as much as other heroes by the silence and mute of Doom since the hero relies more on attacks than abilities.
Additional:
* Doom will be very hestitant to use 
Doom on the Spirit Bear, and using it on Lone Druid himself will not stop the bear from attacking him especially if True Form has already been used.
* 
Devour does not work on the Spirit Bear and pushes the lane so Lone Druid can safely farm under tower.
Spirit Breaker
* 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, Wraith King.
Spirit Breaker
* Charge of Darkness allows Spirit Breaker to catch up to Lycan after he uses Shapeshift.
Additional:
* Vision from Charge of Darkness will easier to catch Lycan 
Shapeshift and Charge of Darkness out of reach Lycan 
Summon Wolves and Lycan's other creeps. Until upgrade Aghanim's Scepter faster catching Lycan Shapeshift.
Spirit Breaker
* Heroes that usually build Linken's Sphere as either a core or situational item: 
Weaver, 
Medusa, Morphling, Queen of Pain, Storm Spirit, Luna, Naga Siren.
Lone Druid
* True Form gives Lone Druid a huge amount of health that no amount of 
Ball Lightning will chip through.
* Entangling Claws can mean a very quick end to the Storm Spirit as it prevents him from using Ball Lightning all together.
* Storm Spirit is a single target nuker, with the Shard Lone Druid can always fear him away from himself or the bear, defending the target he does not go on. This is assuming he cannot try and proc his entangle or a potential 
Skull Basher.
Spirit Breaker
* Heroes that usually build Linken's Sphere as either a core or situational item: Weaver, Medusa, Morphling, Queen of Pain, Storm Spirit, Luna, Naga Siren.
Spirit Breaker
* 
Shukuchi vision can easily target Charge of Darkness before Weaver purchase Linken's Sphere.
Additional:
* Spirit Breaker's strong escape combo abilities from Charge of Darkness and 
Bulldoze can easily catch Shukuchi from Weaver.
* Time Lapse cannot dispel neither Charge of Darkness nor Nether Strike.
* However, Weaver is a common Linken's Sphere wielder. And if he has it, Spirit Breaker will not be able to catch up with Weaver neiter with Charge of Darkness nor with Nether Strike.
Spirit Breaker
* Heroes that can cancel Charge of Darkness: Ogre Magi, Earthshaker, Lion, Rubick, Lina, Luna, Jakiro, Dawnbreaker, Alchemist, Ogre Magi, Axe, Shadow Shaman, Naga Siren, Mars, Bane, Pudge, Clockwerk.
Lone Druid
* Alchemist likes to farm fast and be ahead, unfortunately Lone Druid likes to do the same by taking towers.
* 
Acid Spray will never prove a threat to Lone Druid or his Spirit Bear.
* 
Chemical Rage may not prove so useful once Lone Druid procs entangled keeping him in place.
* 
Monkey King Bar is a very good choice on Lone Druid's Spirit Bear and it directly counters any potential Radiance from Alchemist.
* 
Assault Cuirass is another very good Spirit Bear item that further makes Alchemist vulnerable to physical damage, which is all Lone Druid does.
* Alchemist is not the kind of hero who wants to go on single target summon units, by the time he has killed the Spirit Bear his teammates might had already been slayed by his teammates. Not to mention Lone Druid can just resummon it, even if he is successful.
Spirit Breaker
* Heroes that can slow Charge of Darkness by a huge amount: Venomancer, Viper, Dazzle, Arc Warden, Lion, Huskar, Shadow Shaman, Visage, Undying, Jakiro.
Lone Druid
* Because of his weak laning phase, Lone Druid absolutely overpowers him in the early to mid game. Lone Druid also directly counters most of his abilities.
* 
Flux is nullified when the Spirit Bear is nearby.
* 
Spark Wraith can get soaked by the bear.
* Lone Druid can easily go inside 
Magnetic Field and punish Zet.
Spirit Breaker
* Can easily interrupt and disable Spirit Breaker with hex if being charged.
Spirit Breaker
* Heroes that are squishy by nature are an easy target for Spirit Breaker: Sniper, 
Drow Ranger, Shadow Shaman
Lone Druid
* Lone Druid's early game is good against slow, squishy supports since his bear is very strong early game and an Entangling Claws proc almost always guarantees a kill: Ancient Apparition, Crystal Maiden, Shadow Shaman, etc.
Spirit Breaker
* 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, Wraith King.
Spirit Breaker
* Unlike with other heroes who can summon illusions of themselves, Terrorblade's illusions from 
Conjure Image have different colors than other illusions which can be seen even by enemy team, which can also make Terrorblade weak even against heroes he naturally counters: Bane, 
Lifestealer, Spectre, Chaos Knight, Spirit Breaker, Sniper. Terrorblade's only solution to counter this problem is to get 
Manta Style as quickly as possible.
Spirit Breaker
* Durable heroes: Axe, Dawnbreaker, Bristleback, Mars, Omniknight, Tidehunter, Wraith King, Primal Beast, Underlord.
Lone Druid
* Nukers who have set amounts of damage will really struggle against Lone Druid especially in True Form: Puck, Void Spirit, Mars.
Spirit Breaker
* Ice Wall can slow down Charge of Darkness in its tracks at max level, allowing counterplays such as Cold Snap to end the charge, bursting down with Tornado, Meteor, and right clicks, or even teleporting back to spawn to drag Spirit Breaker into the fountain.
* Cold Snap (if timed right) and Invoker's other disables like Tornado can interrupt Charge of Darkness, especially since Charge is telegraphed by the symbol appearing over head.
Additional:
* 
Cold Snap allows Invoker to interrupt Charge of Darkness and Nether Strike.
* 
Tornado's long range can be used to cancel Charge of Darkness.
* 
Deafening Blast prevents Spirit Breaker from right clicking and thus proccing his Greater Bash.
Lone Druid
* Lone Druid has a very large reserve of health against Invoker abilities, this allows him to survive a large number of attacks from Invoker and kill him, also Entangling Claws reveal invisibility from 
Ghost Walk, which allows the Lone Druid team to catch the popular QW-Invoker

Spirit Breaker
* Heroes with mobility spells like Queen of Pain, Anti-Mage, Phantom Assassin, Riki, Puck, and Spirit Breaker that are cancelled by Frostbite can suffer greatly from the presence of Crystal Maiden. It is absolutely critical, however, to have followup from teammates, as all of the above heroes can make quick work of the squishy Crystal Maiden after they are released from her grip.
Lone Druid
* Lone Druid's early game is good against slow, squishy supports since his bear is very strong early game and an Entangling Claws proc almost always guarantees a kill: Ancient Apparition, Crystal Maiden, Shadow Shaman, etc.
Spirit Breaker
* Heroes who rely on burst damage with magical damage will struggle to kill Primal Beast: Spirit Breaker, 
Gyrocopter, Leshrac
Lone Druid
* 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.
Spirit Breaker
* Heroes that usually build Linken's Sphere as either a core or situational item: Weaver, Medusa, Morphling, Queen of Pain, Storm Spirit, Luna, Naga Siren.
Spirit Breaker
* Heroes that rely on escapes to stay alive can be caught and locked down for a long time: Queen of Pain, Phantom Assassin
Lone Druid
* Riki: 
Smoke Screen can prevent Lone Druid from using True Form and Savage Roar, additionally it cause the spirit bear to miss on attacks which reduce the chances of getting rooted from it, with diffusal Blade, he can keep Lone Druid or the Spirit Bear inside the Smoke.
Spirit Breaker
* Charge of Darkness provides shared vision over its target, keeping track of heroes who rely on invisibility, mobility, or illusions: Riki, Broodmother, Phantom Lancer
Spirit Breaker
* Solar Guardian can save an ally getting targeted and focused by Spirit Breaker.
Lone Druid
* Savage Roar interrupts 
Starbreaker.
* Dawnbreaker is a slow moving hero. Although tanky, Lone Druid can eventually wear her down with his better movement speed.
Spirit Breaker
* Heroes with ways to protect themselves or allies from Spirit Breaker's initiation: Shadow Demon, Outworld Destroyer, Omniknight, Dawnbreaker.
Lone Druid
* Chaos Knight, Lone Druid, Meepo and Arc Warden can be hard targets since Shadow Demon's spells are ill-suited to fight many enemies at once.
Spirit Breaker
* 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, Wraith King.
Spirit Breaker
* 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 his allies and deal with him, preventing him from doing his job. Such heroes include Chaos Knight, Spirit Breaker, Riki, and more.
Spirit Breaker
* With Aghanim's Scepter, Broodmother will gain access to 
Spinner's Snare, which will allow her to create invisible lines on her webs from 
Spin Web that will root, deal damage over time, and reveal enemy heroes if they unwittingly step on them. This allows Broodmother to keep her allies alerted on heroes who rely on invisibility-themed and movement-themed abilities and items to surprise enemy heroes and disrupt ganking attempts of enemy heroes: Phantom Assassin, Nyx Assassin, Mirana, Bounty Hunter, Templar Assassin, Riki, Spirit Breaker, Anti-Mage, Tusk, 
Ursa, Nature's Prophet, 
Enigma, Void Spirit, Magnus etc.
Spirit Breaker
* Charge of Darkness provides shared vision over its target, keeping track of heroes who rely on invisibility, mobility, or illusions: Riki, Broodmother, Phantom Lancer
Spirit Breaker
* 
Searing Chains can stop Charge of Darkness if timed correctly.
* 
Activate Fire Remnant can be used to escape an approaching Spirit Breaker, or lead Spirit Breaker into a bad situation.
* 
Fire Remnant and 
Sleight of Fist allows Ember Spirit to dodge Charge of Darkness if timed correctly.
Lone Druid
* Lone Druid becomes unkillable and impenetrable for Ember Spirit on the central line, as it has a huge reserve of health from the Summon Spirit Bear and a large regeneration from Spirit Link, which is why Sleight of Fist practically does not break through either one or the other on the line, and Lone Druid at this time can easily expel Ember Spirit from the line, push and gain gold and level
* Entangling Claws and Savage Roar abilities completely disable Ember Spirit's ability to dodge abilities or get out of an unpleasant fight for him on Fire Remnant, which can give the Lone Druid team the opportunity to kill him

Lone Druid
* 
Laser blinds Lone Druid, making his attacks miss.
Spirit Breaker
* 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.
Spirit Breaker
*
Pit of Malice can be cast in the path of Spirit Breaker's Charge of Darkness to cancel it.
Atrophy Aura is very hazardous for him in most of the stages, particularly since it also affects 
Greater Bash, hindering Spirit Breaker's main source of damage.
Fiend's Gate provides a way to escape from a gank for Underlord and his teammates. Likewise, 
Fiend's Gate can be used to ambush Spirit Breaker who has little to no ways of intercepting Underlord and his teammates when they use it to move around the map.
