* Frail heroes who lack mobility can also be an easy target to lock down with Chronosphere, such as Drow Ranger, Luna, Sniper, Terrorblade.

* Heroes with high burst damage through their physical attacks or spells can kill Dazzle or his allies before he has a chance to use Shallow Grave. (Lina, Lion, etc.)

* Hex abilities can cancel the channelling of Fiend's Grip : Lion, Shadow Shaman, Dazzle from Aghanim's Shard with upgraded Poison Touch.

* Heroes who can drain mana can make Omniknight useless after he uses one or two abilities: Lion, Anti-Mage, Nyx Assassin.

* Hex greatly reduces Timbersaw's mobility.
* In addition, Lion can follow up with his Earth Spike and Mana Drain combo, preventing Timbersaw to escape with Timber Chain. And he can finish Timbersaw off with Finger of Death if the latter's HP is low enough.

* Time Dilation is similar to a long duration silence, making Timbersaw useless in team fights, or forcing him to adapt his build.
* Time Walk negates Timbersaw's burst damage.
* Time Lock provides magical damage and lock down, and is effective against both Reactive Armor and Timber Chain.
* In conjunction with Time Lock's magical damage, Chronosphere can destroy Timbersaw before he has time to react, and creates a large obstacle that obstruct's Timber Chain's mobility.

* Mana Drain rapidly saps Morphling's already low mana pool, making him unable to use Waveform or Adaptive Strike. Additionally, Hex prevents these abilities as well.
* An Earth Spike and Finger of Death combo can burst an unwary Morphling down if he has his strength fully shifted to agility.

* Time Dilation affects Morphling's low cooldown spells, making them unusable for a long time, rendering Morphling nearly useless.
* Morphling cannot use Attribute Shift while he is inside Chronosphere which makes it easy to kill him.

* Mana Drain depletes Necrophos's mana pool, preventing him from using his abilities.
* Finger of Death deals high magical damage, which becomes amplified by Ghost Shroud.

* Time Dilation while Death Pulse and Reaper's Scythe are on cooldown will make these abilities unusable for a long time, rendering Necrophos nearly useless.
* Necrophos cannot use Ghost Shroud while he is inside Chronosphere which makes it easy to kill him.

* Lion possesses two strong disables in Earth Spike and Hex and heavy magic burst with Finger of Death which help lock him down and prevent him from escaping with Activate Fire Remnant. When getting his Blink Dagger Lion can punish Ember Spirit's overextension immediately, or initiate a fight on him with disables.

* Faceless Void is one of the best heroes against Ember Spirit, providing a lot of ways of dealing with him. Ember Spirit becomes a lot weaker if affected by Time Dilation, as he can no longer spam Sleight of Fist.
* Chronosphere is also a reliable lockdown for Ember Spirit, although it can be evaded sometimes by Activate Fire Remnant. Additionally, Void can easily negate Sleight of Fist damage with Time Walk.
* And finally, Void is a great Diffusal Blade carrier. Not only Manabreak's physical damage not negated by Flame Guard, but it also burns Ember Spirit's mana. That, in turn, prevents him from escaping if he survived Chronosphere.

* Weaver's exceptional ability to elude and survive through clashes and ganks is hard countered by Lion in every aspect.
* Weaver is very mana dependent and has a rather small mana pool in the beginning of the game, of which Mana Drain can deplete and lessen his early game presence.
* Earth Spike followed by Finger of Death in the huge majority of the time is enough to kill Weaver.
* Earth Spike can be point targeted to hit through Shukuchi.
* Hex's has a fair long duration, by which Weaver will not be able to deal damage, or even survive a coordinated attack, and it is single target, of which cannot be dodged.
* Mana Drain easily breaks Linken's Sphere. Its low cooldown allows Lion to infinitely break it whenever it recharges.
* Earth Spike and Hex when paired for the longer lengths of disables may diminish Time Lapse efficiency, possibly causing Weaver to not undo as much damage as he would.

* Time Dilation while Shukuchi and Geminate Attack are on cooldown will make these abilities unusable for a long time, reducing Weaver's escape potential.
* Chronosphere will reveal Weaver during Shukuchi.
Additional:
* The wide range of Chronosphere makes it difficult for Weaver to avoid it with Shukuchi and, once caught, his low survivability makes him an easy kill.
* With no significant source of burst damage, it is easy for Void to survive combat with Weaver using Time Walk.
* Time Dilation will prevent Weaver from using Shukuchi or force him to use Time Lapse to dispel the debuff and re-engage.

* Drow Ranger has a very low health pool, allowing Lion to burst her down.
* Lack of any innate escape mechanism makes her an easy target for Lion's disables.
* Early on she can't deal as much damage to be life threatning. Her Gust is her best weapon against Lion.

* Time Walk can be used to close the distance within Drow Ranger, hindering her Marksmanship bonus.
* Faceless Void can also lock down Drow Ranger with Chronosphere before she has the chance to retaliate due to her low health pool.

* Since Windranger is bad against magical damage, heroes with continuous magical damage or magical nukes can blast her: Zeus, Tinker, Leshrac, Viper, Skywrath Mage, Lion, Lina, Venomancer.

* Time Dilation while renders Windrun movement speed useless slow.
* Time Walk fast cooldown can escaping avoided to Focus Fire. Additionally, Time Walk can dodge to Powershot
* Chronosphere trap can attacking Windranger can not escaping with Windrun.
Additional:
* Time Dilation affects Windranger's low cooldown abilities, making them unusable for a long time, reducing Windranger's escape potential.
* The high mobility provided by Time Walk makes it hard for Windranger to find a good position to land Shackleshot or a full duration of Focus Fire.
* Chronosphere provides excellent lockdown against Windranger, allowing for reliable kills in all stages of the game.
* Faceless Void tends to go for items that require Javelin, such as Maelstrom, Mjollnir and Monkey King Bar, allowing him to bypass the evasion from Windrun.

* Lion's Mana Drain is a headache for Bristleback to deal with during the laning stage, as it denies him the ability to get last hits with Quill Spray.

* Time Dilation prevents Bristleback from spamming his low-cooldown abilities, greatly reducing his damage and effectiveness.
* Chronosphere allows allies to reposition and hit Bristleback from the front, bypassing his defensive bonus from behind.
* Bristleback has no way to prevent Void from using Time Walk.
Additional:
* Time Dilation while Quill Spray and Viscous Nasal Goo are on cooldown will make these abilities unusable for a long time, rendering Bristleback nearly useless.
* Bristleback cannot turn inside the Chronosphere, which makes it easy to attack him from the front, completely bypassing his passive damage reduction.

* Heroes with mana burn: Nyx Assassin, Invoker, Outworld Destroyer, Pugna, Lion

* Time Dilation while Static Remnant and Electric Vortex are on cooldown will make these abilities unusable for a long time, reducing Storm Spirit's potential.
* Faceless Void can catch Storm Spirit during Ball Lightning with a well-timed Chronosphere or Time Walk.

* High priority targets like Queen of Pain, Drow Ranger, Ember Spirit can't get caught out from Lion's long range disables, making it harder to them fulfill their roles, and making it easy to target them.

* Time Dilation affects Queen of Pain's low cooldown abilities, making them unusable for a long time, rendering Queen of Pain nearly useless.
* Chronosphere provides excellent lockdown against Queen of Pain, allowing for reliable kills in all stages of the game.
Additional:
* Time Walk and Backtrack allows Faceless Void to easily negate Queen of Pain's burst damage.
* Chronosphere prevents Queen of Pain from escaping with Blink, and her low survivability makes her an easy kill.
* Time Dilation will prevent Queen of Pain from using her low-cooldown spells or force her to buy Black King Bar or a Eul's Scepter of Divinity to dispel the debuff and re-engage.

* Heroes with high magical burst damage will kill Gyrocopter before he gets to do much: Lina, Lion, Zeus

* Time Walk makes it hard for Gyrocopter to pin down Faceless Void. With Backtrack it also negates most of his attacks.
* Time Dilation will prevent Gyrocopter from using his cooldown spells.

* Hex and Earth Spike can hold Clinkz down, giving him no chance to use Black King Bar or Skeleton Walk.
* Finger of Death quickly kills Clinkz due to his low health.

* Heroes who rely on invisibility, such as Bounty Hunter, Clinkz, Mirana, Nyx Assassin and Riki, as they will be revealed if caught by Chronosphere.

* Heroes that can keep Marci for a long time in one place so she can't pursue her targets, like Bane, Lion, Shadow Shaman, Invoker, Disruptor and Kunkka.

* Heroes that can reliably kite out Dispose, Unleash and dodge Rebound, like Ember Spirit, Void Spirit, Storm Spirit, Anti-Mage, Faceless Void, Puck or always build items like Blink Dagger and Force Staff.

* Lion may upgrade Mana Drain, Hex and Finger of Death through Talent Tree and Aghanim's itens to make them affect secondary targets or turn them into AoE abilities. This can make things difficult for heroes like Phantom Lancer, Naga Siren and Terrorblade, who rely on illusion armies.

* Frail heroes who lack mobility can also be an easy target to lock down with Chronosphere, such as Drow Ranger, Luna, Sniper, Terrorblade.

* Long range disables are really effective against dangerous area controllers and channeling Heroes, like Enigma, Faceless Void or Crystal Maiden, as it may cancel them or prevent enemies from doing further damage while keeping Lion in a relatively safe distance in the warzone.

* In general, heroes with AoE or long range disables (such as Faceless Void with Chronosphere, Pudge with Meat Hook and Elder Titan with Echo Stomp) hinder Crystal Maiden, preventing her from using Freezing Field to help her team in a fight.

* Finger of Death can instantly shred many targets, especially fragile Heroes like Keeper of the Light, Ancient Apparition or Bounty Hunter.

* Heroes who rely on invisibility, such as Bounty Hunter, Clinkz, Mirana, Nyx Assassin and Riki, as they will be revealed if caught by Chronosphere.

* Enigma is fragile, and lacks escapes, being dependent on Blink Dagger for mobility. Ganking Heroes or Heroes with burst damage will likely kill him before he can do anything. Such Heroes include: Lina, Lion, Luna, Puck, Slark, Nyx Assassin, etc.

* Enigma lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Enigma finishes his initiation: Faceless Void, Terrorblade, Ursa, Weaver, Broodmother, Slark, Abaddon, Wraith King, Lifestealer.

* Heroes with high magical burst can easily kill Huskar when he is at low health: Lion, Lina, Skywrath Mage

* Carries that can out damage Huskar will do well against him: Legion Commander, Faceless Void, Troll Warlord, Phantom Assassin.

* Time Walk will easily backtrack Lina's burst damage (especially Laguna Blade) if not timed correctly.
* During Chronosphere, squishy heroes like Lina will be main target of Faceless Void in his ultimate.

* Despite her high mobility, Hex or Earth Spike can lock Phantom Assassin down, make her vulnerable and mitigate her damage output.
* Lion relies entirely on his abilities to be effective, rendering Phatnom Assassin's high evasion through ineffective against him. And Phantom Assassin's low health pool makes her vulnerable to Lion's magical burst without Black King Bar.

* Chronosphere's large obstacle denies Pangolier the room to roll around during teamfights, as well as wasting his ultimate's duration.

* Time Dilation while Spear of Mars and God's Rebuke are on cooldown will make these abilities unusable for a long time, rendering Mars nearly useless.
* Mars cannot turn inside the Chronosphere, which makes it easy to attack him from the back, bypassing Bulwark completely.
Additional:
* Time Walk allows Faceless Void to escape or enter Arena Of Blood, and helps him recover from Mars' burst damage.
* Time Lock's magical damage ignores Bulwark.
* Chronosphere allows Faceless Void to reposition behind Mars, ignoring his Bulwark while he is helplessly frozen in time.

* Hex and Mana Drain can be used to immediately destroy Spectre's illusion when she Haunts. A fast fingered Lion can protect himself and a teammate.
* Hex and Earth Spike are good lockdown spells to control and kill Spectre, especially if she doesn't buy defensive items like Linken's Sphere and Black King Bar.
* Finger of Death can be used to burst down Spectre when she is low on life as she has very poor magic resistance.

* Sniper lacks any protection against Lion's disables early in the game.
* Lion's Earth Spike and Finger of Death may roughly hit Sniper at the latter increased attack range, making it possible to gank and to disable him from afar in clashes.
* Finger of Death is incredibly dangerous for Sniper as it may shred him away from fights, or in the worst scenario, cause his death.

* Frail heroes who lack mobility can also be an easy target to lock down with Chronosphere, such as Drow Ranger, Luna, Sniper, Terrorblade.

* Lion's instant cast point shuts down his initiation and buys time for his allies to catch up.
* Void Spirit has to be cautious when fighting, as he has no protection against Finger of Death. If caught out in a stun, the high magic damage could end him quickly.

* Time Walk can get out to Sprout.
* Chronosphere will interupt his Teleportation and Faceless Void's can attack kill him within Chronosphere.

* Beware of placing the Death Ward if Chronosphere is off cooldown, as it will cancel the effect and leave Witch Doctor vulnerable if he does not react in time.

* Time Dilation can limit Zeus to casting his abilities only once in a fight, effectively serving as a 6/8/10/12 second silence.
* Time Walk negates Zeus's burst damage.
* Chronosphere makes Zeus the best target for Void because of his low mobility.

* Time Walk can easily avoid Invoker's combo damage if doesn't have disables.
* Chronosphere will reveal Invoker during Ghost Walk.
* All of Invoker's hidden cooldowns are affected by Time Dilation, so Faceless Void can easily slow him down a lot.
Additional:
* Time Dilation prevents Invoker from further invoking for the entire duration of the debuff, as well as massively slowing Invoker based on the large amount of spells he has.
* Time Walk will completely negate Invoker's combo damage.
* If Invoker is caught in Chronosphere, he will most likely be the primary target due to the large teamfight contribution he can provide.

* Lion has two low cast point disables (Hex and Earth Spike) to control Ursa before he buys a Black King Bar.
* Hex is one of the few abilities that cannot be dispelled even with an Aghanim's Scepter upgraded Enrage.
* Lion can control Ursa's low mana pool via Mana Drain.

* Wraith King has a very low mana pool and is extremely dependant on it to cast his high mana cost abilities, so Mana Drain will make him struggle way too hard, even not being able to active his passive ability Reincarnation, forcing the Wraith King to buy Aghanim's Shard as soon as possible.
* Althought Wraith King may not be as fragile to struggle against Lion's damage, it's much easier to disable and harass him, as Wraith King doesn't have any mobility at all, his only gap closer being Wraithfire Blast which costs too much mana for his mana pool, and may only affect one target.
Additional:
* While not being able to confront Wraith King by himself, Lion's Mana Drain helps in draining Wraith King's mana, preventing him from reincarnating unless he has his Aghanim's Shard.
* Lion's Earth Spike and Hex provide decent lockdown against Wraith King as well, preventing the latter from benefiting from Vampiric Spirit bonuses.

* Medusa lacks mobility or escape mechanisms. Earth Spike and Hex can neutralize her strong damage potential and allow for Lion's team to focus her down.
* Mana Drain is a perfect ability to weaken Medusa's durability as it can quickly drain her Mana Shield, making her far less tanky. Mana Drain can also be used to restore mana of Lion's allies, which can nullify the mana steal from Mystic Snake.
* Mana Drain, along with Hex, destroy illusions instantly, which may be extremely helpfull and efficient against core builders of Manta Style, like Medusa herself.

* Blade Fury will not protect Juggernaut against Chronosphere or Time Lock.
* Faceless Void can Time Walk out of the range of Omnislash at all points of the game and with ease.

* With a lot of disables with good range, he might cancel your Echo Stomp.
* Mana Drain can be used to drain Elder Titan's already low mana pool.

* If Meepo ganks Lion with Poof and Earthbind, he will be an easy target for Earth Spike & AoE Hex from his level 25 talent.

* Lion may upgrade Mana Drain, Hex and Finger of Death through Talent Tree and Aghanim's itens to make them affect secondary targets or turn them into AoE abilities. This can make things difficult for heroes like Phantom Lancer, Naga Siren and Terrorblade, who rely on illusion armies.

* Heroes with channeling spells, for Chen has no disables on his own, hates buying disabling items and his creeps are often not fast enough to cancel them: Enigma's Black Hole, Witch Doctor's Death Ward, Shadow Shaman's Shackles, Lion's Mana Drain, Bane's Fiend's Grip, Pudge's Dismember, Crystal Maiden's Freezing Field, Pugna's Life Drain, Dawnbreaker's Solar Guardian, and Naga Siren's Reel In from Aghanim's Scepter.

* Heroes with forced movement abilities or non-interrupting forced movement, such as Lion, Drow Ranger, Magnus, Mars, as they can cancel blast-off mid air, removing his ability to initiate or escape.

* Faceless Void can lock Lycan down with his Chronosphere pinning him down as long as his ultimate is up.

* Heroes that can drain mana negatively affect Viper's ability to use Poison Attack, Nethertoxin and Viper Strike: Lion, Anti-Mage

* Sven is very vulnerable to chain stun such as Lion, Shadow Shaman or Magnus.

* Heroes with high burst damage: Lina, Lion, Luna, Nyx Assassin, Queen of Pain.

* Heroes that can kill Death Prophet with nukes can prevent her from using Exorcism to its full duration or using it at all: Lina, Lion, Puck, Morphling.

* 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.

* Heroes who rely on invisibility, such as Bounty Hunter, Clinkz, Mirana, Nyx Assassin and Riki, as they will be revealed if caught by Chronosphere.

* Backline supports (Lion,Crystal Maiden) can keep Puck pinned long enough for a kill.

* Puck cannot use spells if affected by Time Dilation, especially Phase Shift for main survivability as it effectively triples its cooldown.
* Chronosphere can end Puck's life quickly, as stun, more than 3 seconds will be a death sentence to Puck.
* If not silenced, Faceless Void can just Time Walk to undo Puck's Burst damage.
Additional:
* Hard lockdowns such as Chronosphere can be used to quickly take down Puck. Whenever Puck is disabled for longer than 3 seconds, he will usually end up dead.
* As the type of hero that spams spells, Time Dilation counters Puck very effectively. Phase Shift is Puck's main ability for survivability, and Time Dilation effectively triples its cooldown.
* If not silenced, Faceless Void can use Time Walk can easily undo the damage dealt by Illusory Orb, Dream Coil and Dagon.

* Heroes who rely on invisibility, such as Bounty Hunter, Clinkz, Mirana, Nyx Assassin and Riki, as they will be revealed if caught by Chronosphere.

* Any hero who can survive Magnus's initiations and manfight him: Huskar, Faceless Void, Weaver, Abaddon, Troll Warlord, Alchemist, Dragon Knight, Night Stalker, Viper.

* Due to her slow movement speed,heroes with crowd control and slows can shut down Dawnbreaker:Lion, Crystal Maiden ,Venomancer etc.

* Time Walk can easily avoid Dawnbreaker's abilities or to escape her gank attempts and backtrack any damage she deals.
* Time Dilation can prevent Dawnbreaker from using her abilities after initiating, and slowing her down severely.
* Time Lock combined with his high attack speed can lock Dawnbreaker in place, preventing her escape with Celestial Hammer.
* Chronosphere locks down Dawnbreaker in place right after she uses Solar Guardian.
* On the other hand, if Solar Guardian is cast beforehand from afar, it may discourage Faceless Void from casting Chronosphere in its location

* 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.

* Heroes with silences and hard stuns such as Doom, Silencer, and Lion can keep Mirana from Leaping away.

* Heroes who rely on invisibility, such as Bounty Hunter, Clinkz, Mirana, Nyx Assassin and Riki, as they will be revealed if caught by Chronosphere.

* Heroes with silence and mana drain abilites, as Ancient Apparition relies entirely on his abilities: Invoker, Silencer, Nyx Assassin, Skywrath Mage, Shadow Shaman, Lion and etc.

* Hex's instant cast time will force Brewmaster into the awkward situation of needing some form of spell immunity or block to prevent being immediately hex upon blinking in, or wait until Lion has used all his crowd control before entering a fight. His direct magic burst also makes Brewmaster's Drunken Brawler worthless versus Lion.

* Time Walk can break Static Link very quickly, preventing Razor from building up to attack damage.

* Time Walk negates Rupture's damage.
* Chronosphere prevents Bloodseeker from running down and picking off weak enemies during teamfights.
Additional:
* Time Walk will not make Rupture deal damage for the distance jumped and can be used to quickly escape from Blood Rite.

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

* Time Walk and Backtrack allow Faceless Void to easily negate Oracle's burst damage.
* Time Dilation is effective against Oracle's low-cooldown spells. Although dispellable with Fortune's End, it can still catch Oracle off guard if Fortune's End is on cooldown.
* However, False Promise is one of the best abilities in the game to delay or even potentially save any ally caught in Chronosphere. Combined with Fate's Edict, a well-positioned Oracle denies Faceless Void and his team from attempts at solo-Chronosphering key targets to open up a teamfight.

* Chronosphere provides excellent lockdown against Rage.
* Faceless Void's Time Lock stops Lifestealer from getting health regeneration from auto-attacks

* Heroes with abilities or items that can silence or disable Anti-Mage for long periods of time will prevent him from Blinking away: Lion, Silencer, Shadow Shaman, Grimstroke, Witch Doctor, Riki, Faceless Void, Skywrath Mage, Puck.

* Heroes with abilities or items that can silence or disable Anti-Mage for long periods of time will prevent him from Blinking away: Lion, Silencer, Shadow Shaman, Grimstroke, Witch Doctor, Riki, Faceless Void, Skywrath Mage, Puck.

Additional:
* Chronosphere provides excellent lockdown against Anti-Mage, allowing for reliable kills in all stages of the game.
* Time Dilation while Blink and Counterspell are on cooldown will make these abilities unusable for a long time, shutting down his mobility and defensiveness.
* Faceless Void's low mana pool makes him a poor target for Mana Void, although he is very vulnerable should Anti-Mage burn all of his mana.

* Lion may upgrade Mana Drain, Hex and Finger of Death through Talent Tree and Aghanim's itens to make them affect secondary targets or turn them into AoE abilities. This can make things difficult for heroes like Phantom Lancer, Naga Siren and Terrorblade, who rely on illusion armies.

Additional:
* Both Hex and Mana Drain destroy Naga Siren's illusions in an instant, making it hard for her to teamfight or push against a team with Lion. If Lion chooses the AoE effect talent for Hex or the shard for multi-target Mana Drain, it can negate her pushing potential entirely.
* Earth Spike is an AoE disable with good damage. If used well, it can help distinguish the true Naga Siren by the damage they take (illusions take more damage).

* Heroes with nukes: Bane, Lich, Lion, Skywrath Mage

Additional:
* Enchantress is very fragile without any form of magic resistance, allowing Lion to easily burst her down.
* Nature's Attendants is a slow heal, making not as much effective against Lion's burst as it could be.
* Her raw movement speed is a fair escape/mobility mechanism, which may allow her to avoid a blindly cast Earth Spike, but does nothing against the rest of Lion's abilities, since they are single target and can't miss.
* Since Lion's damage comes mostly from his skills, Untouchable does nothing to mitigate it.

* Skywrath's pitiful defences also make him easy meat to heroes with high burst like Juggernaut, Lion, or Phantom Assassin, the latter occasionally downing a support Skywrath in a single Stifling Dagger.

* All of Lion's abilities are active making Demonic Purge break from Aghanim's Scepter useless.
* Hex and Mana Drain can make quick work of whatever illusions you're creating, especially when he acquires his Talents at level 20 and 25.
* An attempt to save an ally using Disruption can easily become a perfect setup for a Earth Spike or Finger of Death with Aghanim's Scepter for the enemy.

* Time Dilation, while Spell Steal with Aghanim's Scepter is on cooldown will make it unusable for a long time, reducing Rubick's potential.
* Rubick's own Chronosphere stolen with Spell Steal cannot stun Faceless Void.

* Ranged heroes that can easily harass Axe: Drow Ranger, Sniper, Lion.

* Finger of Death can instantly shred many targets, especially fragile Heroes like Keeper of the Light, Ancient Apparition or Bounty Hunter.

* Heroes with heavy magical nukes will take advantage of Slark's poor HP or force him to use Shadow Dance early: Lina, Lion, Zeus

* Time Dilation while Dark Pact and Pounce are on cooldown will make these abilities unusable for a long time, reducing his escape potential. However, Time Dilation is dispellable with Dark Pact so it needs to be timed well.
* Chronosphere will not reveal Slark during Shadow Dance but covers the whole duration of Shadow Dance making him unable to use it to attack or escape. Slark still receives the regeneration benefit from Shadow Dance.

* 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.

Additional:
* Lion can continuously Mana Drain Tiny in the early game, depleting his small mana pool for his abilities.

* Heroes with long or multiple disables will prevent Legion Commander from winning Duels: Shadow Shaman, Lion
