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

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

* 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.

* Echo Slam is good against Snowball since it bunches everyone up. This can set up some prime opportunities for Blink Echo Slams.

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

* Fissure interrupts Spirit Breaker during Charge of Darkness.

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

* Earthshaker's many stuns can lock down slippery heroes like Slark in his Shadow Dance and Weaver in his Shukuchi.

* 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.

* Heroes with channeled abilities can be interrupted by a long-range Fissure: Crystal Maiden, Witch Doctor, Bane, Pugna, Pudge.

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

* Heroes with channeled abilities can be interrupted by a long-range Fissure: Crystal Maiden, Witch Doctor, Bane, Pugna, Pudge.

* 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.

* Echo Slam will deal immense damage due to the amount of creeps Chen will have.
* Fissure and Enchant Totem deal large amounts of AOE damage, wearing down non-ancient creeps that Chen converts.

* Earthshaker's Aftershock combos and Fissure can stun Muerta consecutively and minimize Pierce the Veil's effective duration.

* 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.

* 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.

* Treants increase Echo Slam's damage.
* Earthshaker's AoE stuns can hit Nature's Prophet through Sprout, without having direct line of sight, in order to interrupt Teleportation.
Additional:
* Echo Slam can do a lot of damage to Nature's Prophet and his teammates if they stand close to his Treants.

* 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 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.

* 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.

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

* 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.

* 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.

* Earthshaker's many stuns can lock down slippery heroes like Slark in his Shadow Dance and Weaver in his Shukuchi.

Additional:
* Earthshaker's many AoE stuns help lock down Slark and will often waste the duration of Shadow Dance.
* As a frequent Force Staff buyer, he can later on escape or save teammates from Pounce.

* 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.

* Fissure does a great job at interrupting Black Hole immediately, especially with Blink Dagger and Aether Lens.
* Echo Slam's damage potential increases due to the eidolons created by Demonic Conversion.

* Zombies summoned from Tombstone will amplify the damage of Echo Slam due to them increasing the echo damage.

* Earthshaker's AoE stuns can save ally against Duel, forcing Legion Commander to spend Aghanim's Scepter or Black King Bar.

* 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.

* All of his spells can stun Elder Titan and interrupt Echo Stomp's channeling thanks to Aftershock.
* Fissure is particularly good for that purpose thanks to its long range.
* Elder Titan relies heavily on his spells and a chain-stun combo will usually be followed by certain death.

* 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.

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

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

* Heroes with channeled abilities can be interrupted by a long-range Fissure: Crystal Maiden, Witch Doctor, Bane, Pugna, Pudge.

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

* 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 with strong area-of-effect damaging and/or disabling abilities will be able to intercept Underlord and his team when they exit from Fiend's Gate: Luna's Aghanim's Scepter upgraded Eclipse, Dawnbreaker's Solar Guardian, Axe's Berserker's Call, Mars's Arena of Blood, Jakiro's Macropyre, Dual Breath and Ice Path, Naga Siren's Song of the Siren, Razor's Eye of the Storm and Plasma Field, Lina's Light Strike Array, Broodmother's Spinner's Snare from Aghanim's Scepter, Elder Titan's Earth Splitter and Echo Stomp, Alchemist's Unstable Concoction and Acid Spray, Queen of Pain's Sonic Wave, Dark Seer's Wall of Replica and Vacuum, Venomancer's Noxious Plague and Poison Nova from Aghanim's Scepter, Oracle's Fortune's End and Rain of Destiny from Aghanim's Shard, Bloodseeker's Blood Rite, Enigma's Black Hole and Midnight Pulse, Shadow Fiend's Requiem of Souls, Batrider's Aghanim's Scepter upgraded Flaming Lasso, Firefly, Flamebreak and Sticky Napalm, Ancient Apparition's Ice Blast, Sand King's Epicenter, Sand Storm and Burrowstrike, Gyrocopter's Call Down, Ember Spirit's Sleight of Fist, Death Prophet's Exorcism and Silence, Monkey King's Wukong's Command, Crystal Maiden's Freezing Field, Muerta's The Calling, Medusa's Stone Gaze, Zeus's Nimbus from Aghanim's Scepter.

* Melee carries who usually buy an early Black King Bar, and have gap closing abilities can be good against the Arc Warden, such as Slark, Riki, Earthshaker with Aghanim's Scepter, Sven with Aghanim's Scepter etc.

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

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

* 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.

* Having many summons out will cause Echo Slam to deal extra damage.

* 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.

* 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.

* Echo Slam will deal a colossal amount of damage to your Phantasms, as will Fissure at lower levels.
* The area stuns from Aftershock will always stun Chaos Knight's illusions, since they can't use Black King Bar.
* However, Earthshaker should not attempt to fight a farmed Chaos Knight, since he will be completely obliterated by Chaos Knight's colossal damage output, even if he managed to land an Echo Slam
Additional:
* Echo Slam's damage potential increases due to Chaos Knight's Phantasm illusions.

* 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.

* 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.

* Each of Meepo's clones count as real heroes, meaning that an Echo Slam hitting them will deal catastrophic damage to Meepo and his team.
* Eathshaker's AoE stuns can interrupt Meepo's Poof cast animation.
Additional:
* Echo Slam will deal catastrophic damage against a cluster of Meepos and anyone nearby.
* Aftershock allows Earthshaker's abilities to potentially stun any number of Meepos for a fairly long duration, often enough to finish one off.

* 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.

* 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.

* Phantom Lancer's many illusions increase Echo Slam's damage.
Additional:
* Echo Slam deals tremendous damage when multiplied by Phantom Lancer's illusions.
* Earthshaker's AoE abilities can quickly kill Phantom Lancer's illusions.

* Heroes with abilities that can lock down Terrorblade and prevent him from using Sunder: Bane, Batrider, Earthshaker, Elder Titan, Faceless Void, Invoker, Legion Commander, Mars, Primal Beast, Riki, Shadow Shaman, Silencer, Vengeful Spirit, Void Spirit.

* Heroes with wide AoE abilities will reveal Monkey King through Mischief: Necrophos, Phoenix, Alchemist, Earthshaker, Razor, Tinker, Leshrac, Queen of Pain

* Mirror Image's illusions increase Echo Slam's damage.
Additional:
* Earthshaker's strong AoE abilities can clear Naga Siren's illusions, or at least make it easier to distinguish the real one by the damage they take.
* Echo Slam deals more damage against more enemies, which can be devestating against Naga Siren and her illusions.

* 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.

* A well landed Fissure can potentially take Lycan out of the fight for several seconds, who heavily relies on precious seconds from Black king bar and Shapeshift to fight.
* Aftershock reduces the effectiveness of his summons and can prove quite irritating for Lycan.
* Echo Slam is very powerful with the sheer amount of Lycan's units and will cause him to think twice when pushing towers.

* Heroes with channeled abilities can be interrupted by a long-range Fissure: Crystal Maiden, Witch Doctor, Bane, Pugna, Pudge.

* 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.

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