* Void can interrupt Icarus Dive.
* His Crippling Fear's silence will shutdown a spell caster Phoenix.
* However, Phoenix punishes Night Stalker with Supernova because it will turn night into day, and it has a higher priority than Dark Ascension, effectively canceling the passive bonuses Night Stalker gets from Hunter in the Night.

* Any heroes with silences can negate the majority of Outworld Destroyer's damage output: Death Prophet, Night Stalker, Drow Ranger, Doom .

* Heroes with low health: Lich, Crystal Maiden, Lion.

* Heroes who can fight back easily are not ideal matchups for Sven, such as Troll Warlord as mentioned above, Lone Druid and Templar Assassin.

* 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.

* Storm Spirit is absolutely helpless if caught within Night Stalker's silence range.
* Common items a Storm Spirit will build will not remove the AoE silence.
Additional:
* Crippling Fear is a silence that can last up to 8 seconds during night, rendering Storm Spirit tied limited to his items in a fight.
* Dark Ascension allows Night Stalker to initiate on Storm Spirit across the impassable terrain around the middle lane, rendering Storm vulnerable in the early game and prevent him from snowballing.

* 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.

* Puck cannot use any of its normal means to survive should Night Stalker catch it within Crippling Fear, and goes down quickly.
Additional:
* Void is a potent nuke that is devastating to Puck's low health pool.
* Crippling Fear silence can prevent Puck from casting spells, leaving it vulnerable.

* 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.

* Crippling Fear is a good way to shut down and gank Invoker in the early game..
* Void deals good damage to Invoker and makes escaping harder.
* With Hunter in the Night and Void, Invoker can't get away from Night Stalker and won't be able to catch him with Sun Strike during the night.

* 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

* Heroes with low mobility that rely on spells: Zeus, Lina, Crystal Maiden.

* 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.

* 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'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.

* Dark Ascension also allows Night Stalker to fly over Proximity Mines without triggering them.
* Crippling Fear is effective in stopping Techies from using Blast Off and Void is effective in stopping them from running to the safety of their mines.

* 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.

* Void can be used to cancel Requiem of Souls.
* Crippling Fear prevents Shadow Fiend from using Shadowraze or Requiem of Souls.
* With Dark Ascension and Gem of True Sight, Night Stalker can find and kill Shadow Fiend easily. He is also a tanky hero that can fight Shadow Fiend at any stage of the game.

* Crippling Fear silences nearby heroes and cannot be dispelled, which hinders Rubick's way to retaliate when being jumped on.
* With Hunter in the Night and Dark Ascension, Night Stalker can find Rubick easily in teamfights. The two spells grants more than enough damage to hunt Rubick down without defensive items.

* Night Stalker has a huge, almost instant silence through Crippling Fear. The main problem is that he can get it off while Queen of Pain barely has any vision of him if he creeps up to her during Dark Ascension. She'll have to play very carefully before she gets a Black King Bar or a Eul's Scepter of Divinity.

* The long silence at night prevents Clinkz from escaping with invisibility if Night Stalker can sneak up on him. He also has really low base health, so Night Stalker can usually kill him alone during one cast of Crippling Fear at night.

* Crippling Fear makes it so Axe might use Blink Dagger right into an AoE silence in the middle of everyone.
* Void cripples Axe's already bad movement speed and attack speed.
* Hunter in the Night makes it impossible for Axe to catch up to fleeing or escape from Night Stalker during the night.
* Lastly, Dark Ascension gives full vision over Axe before he initiates, making the opponents all recognize his location immediately and allowing Night Stalker to prevent it or vocally tell his team if needed.
* Night Stalker has very high strength gain, even in the lane, so a successful Culling Blade is very unlikely.
* Axe's Blade Mail will likely do nothing to Night Stalker because of his high health and certain requirements for him to do the most damage to be true.

* Crippling Fear prevents Keeper of the Light from using his spells to keep his team alive during team-fights.
* Dark Ascension is very strong against Keeper of the Light, as it allows Night Stalker to jump the backline and quickly kill the squishy Ezalor, especially when combined with the slow from Void.
Additional:
* Keeper of the Light's Aghanim's Scepter upgrade loses much of its power, due to Night Stalker being able to reduce the duration of daytime by a lot.

* Once caught in Bear's Entangle, Nature's Prophet cannot escape with Teleportation.

* With Dark Ascension he can keep vision on Slark, disabling his Shadow Dance regeneration.
* Night Stalker is very fast so without the Pounce in lane, he can simply out distance him during the night.
* Slark is matched in night vision by only a few heroes, Night Stalker happens to be one of them.

* 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.

* Dark Ascension reduces vision for the enemy team, which makes it more difficult for Magnus to initiate with Blink Dagger and Reverse Polarity. It is also more likely that Night Stalker will scout out Magnus with Aghanim's Scepter and a Gem of True Sight, after which he can silence Magnus with Crippling Fear.

* Crippling Fear makes Night Stalker one of the best early game gankers to shut down Anti-Mage.
* Night Stalker's low mana pool causes him to take little damage from Mana Void.

* Crippling Fear can silence Faceless Void for a long time, preventing him from using his Time Walk and Chronosphere.

* 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

* Savage Roar interrupts Starbreaker.
* Dawnbreaker is a slow moving hero. Although tanky, Lone Druid can eventually wear her down with his better movement speed.

* The long silence of Crippling Fear at night prevents Weaver from using his Shukuchi or Time Lapse.
* With Dark Ascension and Gem of True Sight, Night Stalker can easily find and probably kill Weaver.
* Hunter In the Night's attack speed bonus removes The Swarm's beetles very quickly.

* May effortlessly get to and take down Disruptor.
* Void deals heavy single target damage and slow. Lacking innate escape mechanisms justs puts Disruptor in trouble
* Crippling Fear silences, and Disruptor is extremely dependant on abilities to work and to fend for himself.
* Hunter in the Night provides Night Stalker movement speed, attack speed and strengthens his abilities during night time, allowing him to easily catch up and obliterate Disruptor
* With Black King Bar, it's mostly assured to target down Disruptor.

* The long silence of Crippling Fear at night prevents Mirana from escaping with Moonlight Shadow and Leap. She also has really low base health, so Night Stalker can usually kill her during one cast of Crippling Fear at night.
* With Dark Ascension and Gem of True Sight, Night Stalker can find and kill Mirana, and he is a tanky hero capable of fighting Mirana any stage of the game.

* 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.

* Heroes with low mobility that rely on spells: Zeus, Lina, Crystal Maiden.

* 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.

* 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.

* Heroes that have a weak laning stage: Spectre, Nyx Assassin, Clockwerk, Spirit Breaker, Omniknight, Pudge.

* Durable heroes can stand against Tusk during 1v1: Axe, Dragon Knight, Night Stalker, Centaur Warrunner, Wraith King and more.

* Heroes that have a weak laning stage: Spectre, Nyx Assassin, Clockwerk, Spirit Breaker, Omniknight, Pudge.

Additional:
* Void's mini-stun and silence from Crippling Fear will stop Pudge from using Dismember or turning off his Rot.
* Night Stalker has naturally high health, strength gain and common itemization for survivability through magic resistance, making Night Stalker a poor target for Pudge.

* Nukers who have set amounts of damage will really struggle against Lone Druid especially in True Form: Puck, Void Spirit, Mars.

* Heroes with low health: Lich, Crystal Maiden, Lion.

* Heroes with weaker mobility will struggle to keep up with Night Stalker: Gyrocopter, Ursa, Drow Ranger

* Heroes that have a weak laning stage: Spectre, Nyx Assassin, Clockwerk, Spirit Breaker, Omniknight, Pudge.

* Heroes that have a weak laning stage: Spectre, Nyx Assassin, Clockwerk, Spirit Breaker, Omniknight, Pudge.

* Night Stalker's Crippling Fear at night prevents Shadow Walk for an extended period of time and his Void will make Phase Boots useless. If Night Stalker has True Sight, he can shutdown Bounty Hunter's sneak kill.

* Heroes that have a weak laning stage: Spectre, Nyx Assassin, Clockwerk, Spirit Breaker, Omniknight, Pudge.

* Heroes with low mobility that rely on spells: Zeus, Lina, Crystal Maiden.

* Earthshaker must be careful not to use Blink Dagger or Aghanim's Scepter upgraded Enchant Totem to blink into Riki's Smoke Screen or Night Stalker's Crippling Fear, as these field effects will instantly silence Earthshaker and prevent him from initiating.

Additional:
* Fissure has a short stun and creates an impassable ridge. However, Night Stalker can fly over it during Dark Ascension.
* Night Stalker can find Earthshaker, disable his Blink Dagger with Void, and then take him out with Crippling Fear.
* Earthshaker may fail his blink combo against Night Stalker's team if he is not careful, as he can blink into the silence.

* Heroes with weaker mobility will struggle to keep up with Night Stalker: Gyrocopter, Ursa, Drow Ranger

* Heroes that have a weak laning stage: Spectre, Nyx Assassin, Clockwerk, Spirit Breaker, Omniknight, Pudge.

* 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.

* Heroes with long disables, like Lion, Night Stalker, or Legion Commander, can prevent Oracle from using spells or items.

* Heroes that have long silences, such as Night Stalker and Silencer, will prevent Abaddon from saving his allies effectively and disable the active component of Borrowed Time.

* 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.

* With Dark Ascension and Gem of True Sight, Night Stalker can easily find and kill Riki. Riki will also find it harder to kill the tanky Night Stalker than he would many other heroes.

* 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.

* Heroes with silence such as Riki, Silencer, or Night Stalker prevents Skywrath Mage from using his spells.

* 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.

* 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.

* Nukers who have set amounts of damage will really struggle against Lone Druid especially in True Form: Puck, Void Spirit, Mars.

* 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.

* Heroes with weaker mobility will struggle to keep up with Night Stalker: Gyrocopter, Ursa, Drow Ranger

* Night Stalker is one of the best heroes to find (and silence) Tinker in the trees during Dark Ascension.
Additional:
* Night Stalker can easily find Tinker in the trees during Dark Ascension.
* Void's mini-stun will stop Rearm and Keen Conveyance
* Crippling Fear's silence will prevent Tinker from fighting back, as Tinker relies on his spells.
