Weaver
* Heroes with high mobility can be prevented from using it to their advantage with Earthbind, even if they pack a dangerous arsenal: 
Earth Spirit, 
Ember Spirit, 
Storm Spirit, 
Nature's Prophet, 
Phantom Assassin, 
Riki, 
Anti-Mage, 
Weaver.
* See items and abilities disabled by roots
Legion Commander
* When Legion Commander uses 
Duel on one Meepo, he can use his other Meepos to kill her. If he wasn't dueled, he can help the teammate who was duelled to give the teammate the damage instead of Legion Commander.
* However, if Legion Commander picked up an Aghanim's Scepter and she duels one Meepo, that might be the end of Meepo if Legion managed to gather enough damage from previous duels.
Weaver
* Earthshaker's many stuns can lock down slippery heroes like 
Slark in his 
Shadow Dance and Weaver in his 
Shukuchi.
Legion Commander
* Earthshaker's AoE stuns can save ally against Duel, forcing Legion Commander to spend 
Aghanim's Scepter or 
Black King Bar.
Weaver
* Even though 
Linken's Sphere will block your silence, you can cast Arcane Bolt to break it or wait until someone on your team breaks it. In addition, Linken's Sphere builders are usually squishy targets vulnerable to silences: Weaver, 
Queen of Pain, 
Morphling, 
Clinkz, etc. Don't forget that Ancient Seal also increases the magical damage these enemies take, along with silencing them.
Additional:
* 
Arcane Bolt has a long range and a low cooldown, and is a great spell to waste Linken's Sphere. It also serves as an effective spell to harass Weaver with.
* 
Ancient Seal prevents Weaver from using Shukuchi or Time Lapse.
Legion Commander
* 
Mystic Flare can easily burst down Legion Commander while she is Dueling.
Weaver
* 
Arc Lightning has a low cooldown can used to pop his Linken's Sphere.
* 
Lightning Bolt or (
Nimbus upgraded from Aghanim's Scepter) detects Weaver during Shukuchi, preventing his ganks.
* 
Thundergod's Wrath can kill Weaver quickly before he can cast his Time Lapse at low health.
Legion Commander
* Heroes with global abilities can give Legion Commander's opponent an edge in Duels from anywhere on the map: Nature's Prophet, 
Ancient Apparition, 
Zeus, 
Invoker, 
Treant Protector
Weaver
* Shukuchi cannot help Weaver escape from Arena of Blood, and can most likely die if detected through invisibility.
* If pinned to the arena's walls, 
Time Lapse tends to not be enough to save Weaver, as God's Rebuke can keep him burst down thanks to its damage scaling.
* 
The Swarm and 
Geminate Attack are not enough to pierce through Bulwark.
Legion Commander
* Because Duel requires both combatants to face each other, 
Bulwark's effectiveness will be increased by a huge margin, which makes it much more difficult for Legion Commander to win any duels against him.
* 
Spear of Mars and 
God's Rebuke pushes Legion Commander away during Duels against allies.
Additional:
* Bulwark immensely mitigates Duel, even with bonus physical damage, as Bulwark scales by percentage. Mars can also buy time for a dueled ally by pushing Legion Commander away with Spear of Mars.
Legion Commander
* 
Legion Commander is both good and bad vs Mars, on the plus side she can dispel Spear of Mars with 
Press the Attack and is a good 
Silver Edge carrier. However, Mars is not an ideal Duel target, as Bulwark will force her to 1: Buy Silver Edge, and 2: Hit Mars with it before the Duel, allowing a skilled Mars to react, especially with 
Eul's Scepter of Divinity. In teamfights, Mars will happily draw attention after using his abilities, and tank the Duel with all spells on cooldown.
Legion Commander
* 
Gravekeeper's Cloak protects Visage from Legion Commander's attacks for most of Duel's duration.
* Chain stuns from Visage's familiars prevents Legion Commander from winning Duels.
Legion Commander
* 
Cold Embrace saves allies from dying in Duels.
* 
Winter's Curse turns Legion Commander's high damage against her allies, giving the enemy team little time to react.
* However, Winter Wyvern lanes very poorly against Legion Commander due to Press the Attack removing all the debuffs she can give. Winter Wyvern also has little chances of surviving if she gets Dueled herself.
Additional:
* Cold Embrace is very effective against Duel.
* Also, casting Winter's Curse at Legion Commander while an ally is in a Duel will stun her for most of the duration, possibly preventing lethal damage dealt to your ally. It can also turn her high-damage against her teammate.
Weaver
* Shadow Shaman's many disables can lock down Weaver. Even with Linken's Sphere, Weaver might not be able to escape should Shadow Shaman uses Shackles quickly enough following Hex.
* Mass Serpent Wards can make short work of Weaver once he is locked down.
Legion Commander
* Heroes with long or multiple disables will prevent Legion Commander from winning Duels: 
Shadow Shaman, 
Lion
Legion Commander
* 
Pudge, Legion Commander and 
Axe will make the match a living hell for Shadow Shaman, since they are known for surprise attacks from the fog and quickly killing low HP heroes. They can also interrupt Shadow Shaman's channeling, Legion being especially problematic, as she can use Press the Attack on an ally who is hexed as well.
Legion Commander
* 
Astral Imprisonment prevents Legion Commander from killing her opponents in Duels.
Additional:
* Outworld Destroyer can save an ally hero caught by Duel with Astral Imprisonment, and he can inflict heavy damage on Legion Commander with Arcane Orb to aid his ally. However, if he gets caught, he is unlikely to survive the duel, due to his lack of durability.
Legion Commander
* Solar Guardian can save allies who are being dueled and will interrupt her Duel initiation.
Legion Commander
* 
Shallow Grave prevents Legion Commander from killing her opponents in Duels.
* 
Shadow Wave will heal an ally caught in a Duel, as well as dealing damage to Legion Commander.
Legion Commander
* If he isn't broken (break), Abaddon can use Borrowed Time to waste Legion Commander's Duel, As Borrowed Time has a shorter cooldown, Legion Commander can't win duels, effectively reducing her targets by one, Duel also means that Borrowed Time heals Abaddon for the duration of the duel, as Legion can't stop attacking.
Additional:
* 
Aphotic Shield and 
Mist Coil makes it hard for Legion Commander to kill Abaddon's teammates in Duels.
* 
Borrowed Time makes Abaddon nearly impossible to kill in Duels, and often replenishes much of his health because Legion Commander cannot manually stop attacking during Duels.
Legion Commander
* 
Mana Shield makes Medusa very hard to take down in Duels.
* 
Stone Gaze stops Legion Commander from Dueling altogether, regardless of who she targets.
Weaver
* 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.
Weaver
* Shukuchi will trigger extra damage from Rupture.
* Shukuchi's invisibility is detected by Thirst.
* Time Lapse cannot dispel Rupture, preventing Weaver from escaping ganks. However, smart Weaver will buy Linken's Sphere to counter this problem for him.
Additional:
* 
Rupture is particularly crippling against Weaver, who relies on high movement speed from Shukuchi to fight and escape, and it cannot be dispelled by Time Lapse.
* 
Thirst detects Weaver through Shukuchi whenever his health is low.
* 
Blood Rite combined with Rupture forces Weaver to either take damage from the latter, or to get silenced for a long duration.
Legion Commander
* 
Decrepify on either hero stops Legion Commander from completing a Duel, and dissuades her from initiating Duels on ethereal allies.
* 
Life Drain can help Pugna's teammates win a fight, either by killing Legion Commander or replenishing her target's health.
Additional:
* Decrepify prevents Legion Commander from attacking allies during Duel, regardless if it's used on her or on the ally .
* Pugna can easily cast Decrepify, Nether Blast and Life Drain on Legion during the 4/4.75/5.5/8 seconds of duel
Weaver
* 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.
Legion Commander
* Heroes with long or multiple disables will prevent Legion Commander from winning Duels: Shadow Shaman, Lion
Legion Commander
* Lion is extremely dependent on his abilities. Silences like 
Silencer's 
Last Word, magic resistance like 
Oracle's 
Fate's Edict, and dispels like Legion Commander's Press the Attack all make his abilities less effective.
Legion Commander
* 
Paralyzing Cask can save ally from Legion Commander Duel's until she purchases Aghanim's Scepter.
* 
Voodoo Restoration can heal Witch Doctor allies from Duel's.
* 
Death Ward can help Witch Doctor allies from winning Duel's, if, he is not a target.
Weaver
* 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.
Weaver
* Phantom's Embrace and Soulbind prevent Weaver from using Shukuchi or Time Lapse to escape.
* Ink Swell discourages Weaver from moving through and damaging allies with Shukuchi.
Weaver
* 
Ball Lightning allows Storm Spirit to close the gap between him and Weaver in no time. Once locked down with certain items, Weaver is extremely fragile to Storm Spirit and his teammates.
Weaver
* Sprout with True Sight items (
Sentry Ward or 
Dust of Appearance) make it possible to trap Weaver in lane, unless he buys 
Quelling Blade or until he unlocks Time Lapse.
* The Swarm beetles can be destroyed with Nature's Prophet's Treants.
Legion Commander
* Heroes with global abilities can give Legion Commander's opponent an edge in Duels from anywhere on the map: Nature's Prophet, Ancient Apparition, Zeus, Invoker, Treant Protector
Legion Commander
* Legion Commander's 
Overwhelming Odds deals damage for every Treant it hits, which allows it to easily wipe out large waves of them.
Legion Commander
* 
Atrophy Aura's percentage-based damage reduction greatly diminishes Legion Commander's overall damage output, even if she has won many Duels
* Legion Commander cannot get out the way of Firestorm because she is stationary.
Additional:
* Atrophy Aura makes it hard for Legion Commander to win Duels.
* 
Fiend's Gate can be used to save Underlord and his allies from a Duel or to intercept Legion Commander, because outside from Overwhelming Odds, Legion Commander has no other area-of-effect abilities.
Legion Commander
* 
Lucky Shot can disarm Legion Commander and reduce her armor, which can reduce her chances of winning a duel. If an ally is targeted, Pangolier can simply use 
Swashbuckle to inflict it on her.
* If an enemy Pangolier casts a well-timed 
Rolling Thunder before Legion Commander can cast Duel, it might result in her chasing down Pangolier until his or her ultimate ends, whichever duration ends first, resulting in an open window for enemy allies to target Legion Commander, making her vulnerable and susceptible to any source of attacks. If Legion Commander has an Aghanim's Scepter in her inventory, the risk of wasting a solid 8 seconds would result in a futile duel.
* Dueling Pangolier is normally a mistake, Pangolier can disarm you in the duel, and potentially gain some Duel damage, Only duel Pangolier if at least 1 ally is nearby, and he is on low health, And even then, be wary, A good duel can easily turn against you with one Lucky Shot (Due to Lucky Shot lasting 4 seconds).
Additional:
* Swashbuckle can be used to disarm Legion Commander while she is Dueling an ally, granting her opponent a considerable advantage, Lucky Shot lasts 4 seconds at most wasting Legion Commander's entire Duel, (Or half, if Legion Commander has the Scepter).
* Legion Commander will try not to duel Pangolier alone, as she will almost inevitably lose, thanks to Lucky Shot's disarm, If Legion Commander wants to duel a Pangolier, she must be with atleast a teammate, and if she has her scepter, 3 or 4 teammates.
* Legion Commander is often with her allies, allowing you to rack up some considerable damage resistance with Shield Crash.
Legion Commander
* Heroes who can hide the Dueled target (
Outworld Destroyer, 
Shadow Demon, 
Tusk, 
Phoenix with Aghanim's Scepter etc).
Additional:
* Legion Commander relies on her powerful attack and her Duel to be effective. But if Phoenix gets the jump on her first, she can find herself severely slowed, taking heavy damage, and find herself unable to Duel a burning Supernova.
* It must be noted that Press the Attack will both dispel the attack slow of Fire Spirits and grant her or whoever she targets bonus attack speed. This allows her to easily destroy a Supernova if caution is not taken to prevent this from occurring. As such, it would be a better decision to simply avoid a farmed or skilled Legion Commander instead of attempting to overpower her.
* If an ally is caught by Duel, Phoenix can use Sun Ray to heal the ally and damage Legion Commander, possibly swinging the Duel in their team's favor. Or with Aghanim's Scepter, Phoenix can save an ally from dying in Duel with Supernova and cancel the Duel as well.
Legion Commander
* Heroes with global abilities can give Legion Commander's opponent an edge in Duels from anywhere on the map: Nature's Prophet, Ancient Apparition, Zeus, Invoker, Treant Protector
Legion Commander
* 
Troll Warlord's melee bash and high attack speed can often help him and his allies win Duels against Legion Commander.
Legion Commander
* Heroes who can hide the Dueled target (Outworld Destroyer, Shadow Demon, Tusk, Phoenix with Aghanim's Scepter etc).
Additional:
* Walrus PUNCH! makes Legion Commander lose Duel easily, especially when she doesn't have 
Blade Mail. Tusk can also snowball dueled allies, preventing them from taking damage for a large portion of the duel's duration.
Weaver
* Smoke Cloud prevents Shukuchi and Time Lapse, leaving Weaver helpless against Riki.
* The Swarm is ineffective against Riki because invisibility instantly removes the beetles.
Legion Commander
* Heroes with abilities that blind or cause Legion Commander to miss will prevent her from winning Duels: 
Arc Warden, 
Keeper of the Light, Riki, 
Tinker
Legion Commander
* Another great threat to Riki since her Duel forces him to fight from the front and expose him for the entire duration, almost always guaranteeing an easy win (unless Riki has allies helping him).
* 
Moment of Courage can become hard to deal with as it doesn't cease with silence.
Weaver
* Heroes that lack burst damage will have a difficult time taking down Monkey King, and fare badly against Jingu Mastery: Legion Commander, 
Lifestealer, Weaver, 
Wraith King
Legion Commander
* Heroes that lack burst damage will have a difficult time taking down Monkey King, and fare badly against Jingu Mastery: Legion Commander, Lifestealer, Weaver, Wraith King
Weaver
* Heroes that can maintain vision on Monkey King can see when he uses Tree Dance: 
Bloodseeker, Treant Protector with Eyes In The Forest, 
Sniper, Weaver
Legion Commander
* Fate's Edict prevents Legion Commander from attacking for a few seconds, potentially saving Oracle's ally.
* 
Fortune's End dispels Press the Attack's healing and attack speed buff, as well as the movement speed bonus from Overwhelming Odds.
* 
False Promise protects allies and prevents Legion Commander from winning Duels and gaining bonus damage.
Additional:
* Provided that the enemy team does not have an Axe, Oracle can guarantee that his ally survives for the duration of the Duel with False Promise and has decent nuke potential to help ally to win a Duel. He can also disarm Legion Commander with Fate's Edict.
* Oracle can dispel enemy buffs like Overwhelming Odds and Press the Attack with Fortune's End.
Legion Commander
* Heroes with long disables, like Lion, 
Night Stalker, or Legion Commander, can prevent Oracle from using spells or items.
Legion Commander
* Battery Assault's mini-stuns can severely disrupt Legion Commander's attack animation when she enters a Duel, potentially saving Clockwerk (or his allies) and possibly even giving him an edge in securing a win himself.
* Power Cogs pushes Legion Commander away from Clockwerk's allies when she enters a Duel.
Weaver
* 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.
Legion Commander
* Invoker's spells will disable and destroy Legion Commander while she's locked in a Duel.
Legion Commander
* Heroes with long lockdowns: Shadow Shaman, Legion Commander.
Legion Commander
* 
Purification prevents Legion Commander from killing her target, and will always hit her during Duels.
* 
Guardian Angel completely wastes Duel's duration and can save an ally across the map when upgraded with Aghanim's Scepter.
Additional:
* Both Guardian Angel and Purification are perfect counters against Duel.
Weaver
* Heroes that rely on slows or low-duration stuns have trouble catching Weaver: 
Omniknight, 
Lich.
Weaver
* Low-health, normally mobile carries who rely entirely on raw attack damage are vulnerable to Bane's nukes and disables: Anti-Mage, Clinkz, 
Drow Ranger, Faceless Void, 
Gyrocopter, 
Juggernaut, 
Meepo, 
Mirana, 
Monkey King, Morphling, Phantom Assassin, 
Phantom Lancer, Riki, 
Shadow Fiend, Slark, Sniper, Terrorblade, Troll Warlord, Weaver.
Legion Commander
* Bane has powerful single-target abilities that can help his allies win Duels, or at least cripple Legion Commander for the duration.
* Nightmare can waste Duel's entire duration as the dueled units transfer the Nightmare back and forth. This may be prevented if a non-Dueling unit attacks the Nightmared Dueler.
Additional:
* 
Enfeeble, 
Nightmare and 
Fiend's Grip all prevent Legion Commander from winning Duels, especially when Bane has 
Blink Dagger.
Weaver
* Heroes who commonly buy Linken's Sphere: 
Luna, Weaver, Morphling, Queen of Pain, Ember Spirit.
Legion Commander
* Heroes with strong dispels can dispel Bane's disables from their allies: Oracle, Legion Commander, Omniknight.
Weaver
* Berserker's Call is one of the best ways to lock down Weaver before he has a chance to use Time Lapse. It can also catch Weaver in Shukuchi.
* Weaver's high attack speed, along with high attack damage from Geminate Attack, triggers Counter Helix continuously and the output damage would be returned by Blade Mail.
Additional:
* 
Berserker's Call is one of the best ways to lock down Weaver before he has a chance to use Time Lapse. It can also catch Weaver in Shukuchi.
* Due to his fast attack speed from Geminate Attack and items that give attack speed, 
Counter Helix will activate a lot, and the damage would be returned by Blade Mail, which hurts Weaver far more than it hurts Axe.
* 
Culling Blade can finish off Weaver's low health pool before he escapes with Shukuchi and Time Lapse.
* 
Battle Hunger is a good tool to pop Weaver's Linken's Sphere due to its low cooldown.
Legion Commander
* Long lockdown is a great way to deal with Axe to prevent Berserker's Call from being used, heroes such as Legion Commander, 
Beastmaster and 
Primal Beast are good examples of this.
Weaver
* 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.
Weaver
* 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.
Weaver
* Weaver has poor health, relying on Shukuchi and Time Lapse to survive, With Jakiro's considerable arsenal of stuns, Weaver cannot initiate on Jakiro without being punished heavily or even killed in return.
* While difficult, Ice Path can catch Weaver during Shukuchi, And since Shukuchi only lasts 4 seconds while Ice Path's stun lasts 3.5, the stun from Ice Path will strip him of his escape.
* Weaver has to be very careful casting Time Lapse around Jakiro, as it could very easily put him inside of a Macropyre or Ice Path.
Weaver
* Heroes with good mobility to avoid Jakiro's abilities and with good chase to punish Jakiro from pushing a tower: Bloodseeker, Ember Spirit, Juggernaut, Phantom Assassin, Weaver.
Weaver
* A well-timed Fireblast with Multicast can prevent Weaver from escaping with Shukuchi and even Time Lapse.
* Ignite's high damage early on applies heavy pressure onto Weaver's very small health pool.
* However, the slow from Ignite is generally useless against Shukuchi, and Time Lapse dispels it if needed.
Legion Commander
* Heroes rely on their debuff to control the opponent will have a hard time against Press the Attack: 
Venomancer, Earth Spirit, 
Ogre Magi
Weaver
* Arcane Bolt has a long range and a low cooldown, and is a great spell to waste Linken's Sphere. It also serves as an effective spell to harass Weaver with.
* Ancient Seal prevents Weaver from using Shukuchi or Time Lapse.
Legion Commander
* Heroes with low health will die easily during Duels, and can be farmed for damage in the early game: 
Crystal Maiden, Lich, 
Techies, 
Rubick
Legion Commander
* Song of the Siren lasts long enough to prevent a successful Duel (but only if Naga wasn't the target).
Legion Commander
* Heroes who rely on illusions will see them destroyed easily by Overwhelming Odds: Phantom Lancer, 
Chaos Knight, Terrorblade, Naga Siren
Legion Commander
* 
Untouchable makes Enchantress one of the hardest heroes for Legion Commander to Duel against, as her attack speed will be significantly slowed for the duration, even with any form of spell immunity.
* Meanwhile, when Enchantress is not a target, Enchantress can use both 
Impetus and 
Enchant on Legion Commander to help her ally win the Duel.
Weaver
* Heroes with haste can negate Enchant's slow: Weaver, 
Dark Seer, 
Lycan, 
Centaur Warrunner.
Weaver
* Weaver can easily kill Chen's creeps and kite Chen with The Swarm and Shukuchi.
* Neither Chen nor his converted creeps have burst damage at all, so Weaver will always have plenty of time to save himself with Time Lapse or his allies with Aghanim's Scepter upgraded Time Lapse.
Legion Commander
* Chen's fragility and low mobility make him an enticing Duel target.
* Overwhelming Odds and Moment of Courage can take advantage of converted creeps's numbers.
* With enough damage from Duel stacks, Legion Commander can also often kill any of Chen's unfortunate allies before he can use Hand of God.
Additional:
* Chen's frailty and low mobility make him an enticing Duel target.
* Overwhelming Odds and Moment of Courage can take advantage of converted creeps' numbers.
* With enough damage from Duel stacks, Legion Commander can also often kill any of Chen's unfortunate allies before he can use 
Hand of God.
Weaver
* Time Lapse with Aghanim's Scepter dispels Flaming Lasso when used on allied hero.
* Linken's Sphere is core item for a Weaver making him a hard target for Lasso during entire game.
Legion Commander
* Press the Attack dispels Flaming Lasso.
* Batrider is unlikely to win a Duel in any stage of the game.
Weaver
* Shukuchi ignores slows and allows Weaver to escape Viper's onslaught.
* Time Lapse dispels 
Poison Attack and 
Corrosive Skin and undoes poison damage.
* Weaver's high burst damage allows him to kill Viper before being killed.
Legion Commander
* Viper's frailty and low mobility make him an enticing Duel target and Corrosive Skin doesn't protect him against Legion Commander physical attacks.
* Press the Attack can dispel Poison Attack.
* Viper slows can easily negate by Overwhelming Odds movement speed.
Weaver
* Shukuchi allows Weaver to close the gap between himself and Sniper with high speed, and to maneuver through teamfights to get on top of him.
* A combination of The Swarm and 
Desolator tears through Sniper's low armor.
Legion Commander
* Sniper's low mobility and lack of defensive abilities make him an easy gank target for the entire game, especially if Blink Dagger is picked up.
Weaver
* Shukuchi grants Weaver invisibility and a high degree of mobility for a short time, which can make him a difficult target to hook.
* The Swarm beetles are difficult for Pudge to remove, due to his low base attack time and poor agility. Additionally, it can be used to can scout out Pudge's location.
* Should an ally get snagged by Meat Hook, Weaver can use Aghanim's Scepter upgraded Time Lapse on them to send them back to where they were before hooked, even if Pudge has already started to Dismember them.
Additional:
* While Weaver is in Shukuchi, 
Rot doesn't slow him and 
Meat Hook is easy to avoid.
* Even when hooked, Weaver can use Time Lapse, negating both the damage and displacement.
* Pudge has low armor and low attack speed, making him susceptible to The Swarm and physical attacks.
* 
Dismember is easy to block with Linken's Sphere and it's the only way to break Weaver's Linken Sphere.
* However, the long duration stun of Dismember can be dangerous for Weaver.
Legion Commander
* Legion Commander can use Press the Attack on an ally to dispel Dismember. The bonus health regeneration also partially counters the damage of Rot
* Duel can be used on Pudge whilst Rot is active, disabling toggling which may result in a lethal health drain that leaves Legion Commander with a successful duel.
Weaver
* Shukuchi gets Weaver in front of Bristleback, negating the protection from 
Bristleback.
* Weaver's mana break talent depletes Bristleback's mana pool, preventing him from spamming abilities.
Legion Commander
* Duel makes Bristleback fight Legion Commander face to face, forcing him to take full damage.
* Press the Attack dispels the slow from stacks of Viscous Nasal Goo.
Additional:
* When dueled, Bristleback will have to face Legion head on, not allowing his passive Bristleback to come into effect.
Weaver
* Heroes whose core item builds includes 
Monkey King Bar: Faceless Void, 
Windranger, Weaver, Juggernaut.
Legion Commander
* Duel's long duration prevents Terrorblade from swapping his health with 
Sunder.
* Overwhelming Odds deals high damage to Terrorblade's illusions.
Weaver
* Weaver doesn't care much about Lich's slows thanks to Shukuchi.
* If he sees Chain Frost is targeting him, he can easily isolate himself with Shukuchi so that it stops bouncing around.
* Unless Lich bursts Weaver immediately, Lich has no hard disables or silences to prevent him from using Time Lapse.
Legion Commander
* Heroes with low health will die easily during Duels, and can be farmed for damage in the early game: Crystal Maiden, Lich, Techies, Rubick
Weaver
* Weaver's Shukuchi allows him to escape from Warlock's Upheaval with high move speed.
* Time Lapse allows Weaver to ignore damage from Warlock's Golem and escape.
Legion Commander
* Heroes who rely on summons will see them destroyed easily by Overwhelming Odds: Lycan, Arc Warden, 
Warlock, 
Chen
Weaver
* A well-timed use of The Swarm provides vision over heroes with high mobility: Anti-Mage, Arc Warden, Dark Seer.
Legion Commander
* Duel renders Anti-Mage's escape capabilities with Blink and Counterspell useless. Blade Mail and Moment of Courage work well against Anti-Mage's relatively low health.
* A good initiation from Legion Commander and her team is enough to effortlessly kill Anti-Mage.
Additional:
* 
Counterspell offer no protection against Duel at all.
* Duel locks down Anti-Mage for a long duration, preventing him from escaping with 
Blink. One successful Duel initiation is usually enough for Legion Commander's team to kill Anti-Mage.
Weaver
* Heroes who can dodge Earth Spirit's abilities: Ember Spirit, 
Puck, Weaver
Legion Commander
* Heroes rely on their debuff to control the opponent will have a hard time against Press the Attack: Venomancer, Earth Spirit, Ogre Magi
Legion Commander
* Press The Attack can save her allies dispels the stun from Shackleshot.
* Duel can lock down Windranger before she can escape with Windrun.
* Legion Commander tends to go for Blade Mail, which returns the damage she takes from Focus Fire.
Weaver
* Marci's Dispose is blocked by Linken's Sphere which is a common item for Weaver.
* Shukuchi allows Weaver to escape from 
Rebound slow.
* The swarm beetle require 4 hits to kill. Weaver can use it on her when she use Unleash. This give Marci a hard choice: ignore The swarm and her armor keep decreasing or kill the beetle and wasting 4 attacks of Unleash.
Weaver
* Brewmaster is slow and has low armor, making his laning stage very difficult against Geminate Attack.
* Apart from the slow moving 
Hurl Boulder, which can be disjointed, he has no control to catch Weaver.
Legion Commander
* Duels prevents Queen of Pain from using Blink, which may force her to purchase a Linken's Sphere
* Because Queen of Pain is also not a right-click hero, Legion won't have much difficulties in duels.
* Press the Attack dispels Shadow Strike's debuff.
Legion Commander
* Duel is a great initiation to kill Death Prophet before she can cast Exorcism. Furthermore, Legion Commander often builds Blade Mail and can reflect Exorcism's damage to kill Death Prophet easily.
Legion Commander
* 
Searing Arrows and Clinkz physical damage items are almost suicidal when used on Legion Commander, as it invites an instant Duel and Legion Commander herself is a natural Blade Mail carrier.
* Duel locks down Clinkz for a long duration, preventing him from escaping with 
Skeleton Walk.
Weaver
* Geminate Attack works on 
Tombstone, allowing Weaver to kill it quickly.
* Zombies attacking Weaver disappear once he goes invisible with Shukuchi.
* Undying has no way to catch a mobile Weaver.
Legion Commander
* Overwhelming Odds's damage stacks with each enemy unit in its radius. If this hits Broodmother and a large number of spiders it can deal significant amounts of damage.
* Moment of Courage has a high chance to proc if Broodmother and all of her spiders are attacking her.
* Duel can keep Broodmother in place long enough for Legion's team to kill her.
Additional:
* Overwhelming Odds is great at killing many stacked up spiderlings, thus giving Legion Commander a large buff.
* Duel is a reliable way to lock down Broodmother, preventing her from running into the treeline.
Legion Commander
* Duel pierces spell immunity and forces him to attack Legion Commander, making him unable to use 
Omnislash.
Weaver
* Though The Swarm can be blocked by Rage, it can be used to lower Lifestealer's already low armor, making him even more vulnerable to physical damage while Rage is on cooldown.
* Lifestealer has no strong disables on his own and thus cannot catch up with nor escape from Weaver's Shukuchi.
* Lifestealer's reliance on meticulous auto-attacks will not help against Time Lapse, which can undo Lifestealer's already slow build-up of damage. Aghanim's Scepter upgraded Time Lapse can also be used to save allies from getting killed by Lifestealer, but that will require targeting the allied hero rather than just pressing the button that will trigger the Time Lapse.
Additional:
* 
Open Wounds's slow is ignored by Shukuchi.
* Lifestealer has no other lockdown and relies on being on top of enemies; Weaver can kite him with ease.
Weaver
* Heroes who often build Linken's Sphere: Weaver, Morphling, Medusa.
Legion Commander
* Heroes who rely on illusions will see them destroyed easily by Overwhelming Odds: Phantom Lancer, Chaos Knight, Terrorblade, Naga Siren
Additional:
* Overwhelming Odds deals high damage to Phantom Lancer's illusions.
* Duel's long duration prevents Phantom Lancer from using Doppelganger.
Weaver
* In general, Timbersaw struggles against highly mobile heroes that can avoid his abilities: Puck, Weaver, Ember Spirit and others.
Weaver
* Heroes with Linken's Sphere as core item: Weaver, Morphling, Medusa.
Weaver
* Any hero who can survive Magnus's initiations and manfight him: 
Huskar, Faceless Void, Weaver, Abaddon, Troll Warlord, 
Alchemist, 
Dragon Knight, Night Stalker, 
Viper.
Weaver
* Heroes that are hard to kill without lockdown: Puck, Weaver.
Legion Commander
* Heroes with strong area damage to destroy Phantasm illusions: Axe, Ember Spirit, Legion Commander, Phoenix
Legion Commander
* Heroes rely on their debuff to control the opponent will have a hard time against Press the Attack: Venomancer, Earth Spirit, Ogre Magi
Additional:
* Press the Attack dispels Venomous Gale and Poison Sting from Legion Commander or her teammates.
* Venomancer is an ideal target for Duel due to his lack of mobility and low starting health.
Legion Commander
* Special mention to Legion Commander, as she can lock down Void Spirit for a long amount of time without worrying too much about being killed by him during the Duel.
Weaver
* Heroes with one single-target abilities such as Wraith King, 
Necrophos, or 
Doom will struggle against Weaver's Linken Sphere.
Weaver
* Heroes with good escapes can usually outmaneuver and escape from Spectre: Slark, Clinkz, Weaver
Legion Commander
* Heroes who rely on summons will see them destroyed easily by Overwhelming Odds: Lycan, Arc Warden, Warlock, Chen
Weaver
* 
Bounty Hunter has a cheap way to break Linken's Sphere and keep track of Weaver while he is using Shukuchi, though both can be dispelled with Time Lapse.
Weaver
* Weaver with Time Lapse
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with 
Life Break
* Juggernaut with 
Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with 
Rage and 
Infest
* Naga Siren with 
Mirror Image
* Omniknight with 
Heavenly Grace
* Oracle with Fortune's End and False Promise
* Phantom Lancer with 
Doppelganger
* Slark with 
Dark Pact
* Ursa with 
Enrage
* Weaver with Time Lapse
* 
Tidehunter with 
Kraken Shell when damage received reaches the threshold.
Legion Commander
* Legion Commander with Press the Attack
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with Mirror Image
* Omniknight with Heavenly Grace
* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Weaver
* Dark Seer's only disable is Vacuum. Though he starts off with high armor and health, he'll eventually have a hard time dealing with high mobility heroes such as Weaver or Queen of Pain.
Weaver
* Frostbite will reveal invisible heroes for its duration, making it a good tool against any such hero (Riki, Bounty Hunter, Weaver, or Clinkz for example), or as a soft counter to 
Shadow Blade, if it is used first. This can be an amazing tool to ensure that Dust of Appearance is used on the unit in question, and not wasted in not catching anything.
Legion Commander
* Duel is a great initiation to target Crystal Maiden with, as it prevents her from using Freezing Field or any other abilities and allowing the enemy team to quickly kill her before she can aid her team in a fight.
Legion Commander
* Heroes with abilities that blind or cause Legion Commander to miss will prevent her from winning Duels: Arc Warden, Keeper of the Light, Riki, Tinker
Legion Commander
* Press the Attack can dispel Blinding Light or Solar Bind from a hero.
* Duel can be used to instantly take Keeper of the Light out of a team-fight.
Legion Commander
* Heroes with abilities that blind or cause Legion Commander to miss will prevent her from winning Duels: Arc Warden, Keeper of the Light, Riki, Tinker
Legion Commander
* Press the Attack can dispel Laser's blind while providing great attack speed and health regeneration.
* Once caught in a Duel, Tinker, who completely relies on his spells to be effective, has little chances of survival with his low health pool and armor.
Legion Commander
* Heroes with global abilities can give Legion Commander's opponent an edge in Duels from anywhere on the map: Nature's Prophet, Ancient Apparition, Zeus, Invoker, Treant Protector
Weaver
* Time Lapse allows Weaver (or an ally if upgraded with Aghanim's Scepter) to regain HP while affected by Ice Blast.
* Shukuchi completely ignores the slow from Ice Vortex and helps him escape the freeze range of Cold Feet.
Additional:
* 
Cold Feet is extremely easy to nullify with Shukuchi.
* 
Ice Vortex does not slow Weaver in Shukuchi.
* Time Lapse will still affect his health, even when hit by 
Ice Blast.
* Ancient Apparition has no escapes or saves and is very squishy, making him an easy target for Weaver to get on top of.
Legion Commander
* Wraith King's 
Reincarnation allows him to severely punish Legion Commander after he revives, as her abilities are on cooldown. Legion Commander is still awarded a Duel win if Wraith King reincarnates.
Additional:
* Wraith King makes a poor Duel target, as he can be already quite hard to bring down once, and then you have to worry about his second life.
* However, even if Legion Commander does win the duel when Reincarnation is off cooldown, she still receives the permanent victory damage bonus because taking down Wraith King's first life still counts as a "kill".
Weaver
* 
Wraithfire Blast is easy to disjoint with Shukuchi or Time Lapse, and it's the only way to break Weaver's Linken Sphere.
* Wraith King has no other disables and no mobility, allowing Weaver to chase or escape Wraith King as he wishes.
* With the Mana Break talent and 
Diffusal Blade, Weaver can prevent Reincarnation from triggering until Wraith King gets his shard.
Additional:
* Weaver can run away after killing Wraith King once thanks to Shukuchi.
* Wraithfire Blast is quite predictable. If Weaver is quick, he will disjoint it with Shukuchi and proceed to chase Wraith King down.
* Shukuchi does have a fade time. They cannot disjoint it if you use it right next to them. They will be stunned and take damage; however they will still become invisible if they used Shukuchi before the stun hits.
* Weaver can easily harass Wraith King out of his lane thanks to his high base damage and Geminate Attack.
* Weaver can burn Wraith King's mana quickly with his {ValueColor:1|Mana Break|15tal} {Symbol:Talent} talent or Diffusal Blade, until Wraith King purchases Aghanim's Shard to remove Reincarnation's manacost.
Legion Commander
* A well-timed 
Eclipse before a Duel usually prevents Legion Commander from winning Duels, if Luna is the target.
* Meanwhile, when Luna is not a target, Eclipse and 
Lucent Beam can also help an ally win a Duel against Legion Commander.
* However, skilled Legion Commander will always buy a Black King Bar to block Eclipse and Lucent Beam or Aghanim's Scepter to reduce it's damage.
Additional:
* A well-timed Eclipse before a Duel usually prevents Legion Commander from winning Duels if Luna is the target. Luna can also buy Linken's Sphere to block Duel.
* Meanwhile, when Luna is not a target, Eclipse and Lucent Beam can also help an ally win a Duel against Legion Commander.
* Bear in mind, however, that skilled Legion Commander will always buy a Black King Bar to block Eclipse and Lucent Beam or Aghanim's Scepter to reduce their damage.
Weaver
* Escape-type carries: Slark, Storm Spirit, Weaver.
Legion Commander
* Heroes that can keep Luna locked down for a long time can be a threat (she is very item and spell dependent): Faceless Void, Legion Commander, Doom.
Legion Commander
* Magnetic Field prevents Legion Commander from getting wins with Duel.
Additional:
* 
Magnetic Field prevents Legion Commander from easily gaining wins with Duel.
Weaver
* A well-timed use of The Swarm provides vision over heroes with high mobility: Anti-Mage, Arc Warden, Dark Seer.
Legion Commander
* Heroes who rely on summons will see them destroyed easily by Overwhelming Odds: Lycan, Arc Warden, Warlock, Chen
Weaver
* Weaver cannot Time Lapse out of Huskar's burn damage.
Weaver
* Heroes with abilities that reduce armor will make Huskar very vulnerable: Weaver, 
Dazzle, 
Bristleback, 
Vengeful Spirit.
Legion Commander
* Carries that can out damage Huskar will do well against him: Legion Commander, Faceless Void, Troll Warlord, Phantom Assassin.
Additional:
* Life Break is almost suicidal when used on Legion Commander, as it invites an instant Duel and Legion Commander herself is a natural Blade Mail carrier.
* Huskar's low survivability and mostly on low health make him particularly vulnerable to Legion Commander's high physical damage.
Weaver
* Techies is very good against roaming supports and gankers such as Bounty Hunter, Riki, Weaver, 
Earthshaker, 
Nyx Assassin, etc. that are constantly moving around the map.
Legion Commander
* Heroes with low health will die easily during Duels, and can be farmed for damage in the early game: Crystal Maiden, Lich, Techies, Rubick
Legion Commander
* 
Static Link drains Legion Commander's accumulated damage, effectively neutralizing her overall primary advantage, and prevents her from winning Duels.
* 
Storm Surge's movement speed buff makes Razor and his allies harder to catch and initiate.
* 
Eye of the Storm, if used beforehand, will always hit Legion Commander during Duels, due to her forced proximity. This drastically lowers her survivability during Duel.
Weaver
* Shukuchi can break Static Link with little trouble.
* Time Lapse can easily be used to avoid damage from Plasma Field and can recover the damage done from Static Link and Eye of the Storm.
* Eye of the Storm can't kill bugs from The Swarm.
Legion Commander
* 
God's Strength makes Sven one of the worst heroes to Duel.
* 
Storm Hammer can be used to interrupt Duels.
* 
Warcry gives a big boost in passive defensive ability with the active component to nearby allies.
* With the Aghanim Shard Warcry also gives nearby allies passive increases.
Weaver
* Sven can be easily kited since Weaver is a natural Linken's Sphere carrier and Sven relies on Storm Hammer to disable and kill a hero.
Legion Commander
* Heroes who can hide the Dueled target (Outworld Destroyer, Shadow Demon, Tusk, Phoenix with Aghanim's Scepter etc).
Additional:
* Disruption can save allies and mess up an initiation from an enemy Legion Commander. Using Disruption on your ally that is affected by Duel will leave her totally exposed without the benefit of the life steal from Moment of Courage. A precise decision to Disrupt Legion Commander or her victim is crucial to waste Duel's potential.
* Demonic Purge cannot be dispelled by a hard dispel from Press the Attack, which in turn can be dispelled by your ultimate.
Weaver
* You can potentially kill a fragile Weaver by using Disruption during Shukuchi with a well-placed Sentry Ward, wasting the Shukuchi. But odds are he'll wait to get low health, Time Lapse the damage away and Shukuchi away once more.
Legion Commander
* Enigma can be a perfect counter-initiator with his ultimate. A perfectly timed Black Hole will turn the tide of any initiation, especially from heroes like; 
Spirit Breaker, Legion Commander, Axe, Puck, and 
Slardar.
Weaver
* 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.
Legion Commander
* 
Fury Swipes can give Ursa the edge in Duels.
* Enrage's instant cast time allows it to be used before Legion Commander initiates a Duel, causing Ursa to take almost no damage for a brief period of time.
* However, Duel stops Ursa from casting Enrage at the most critical moment
Weaver
* The swarm beetle can waste Ursa's 
Overpower attacks.
* Ursa has no inherent way of disabling a slippery Weaver by preventing him from Shukuchiing or Time Lapseing away, as the slow from Earthshock is useless against Shukuchi's haste effect.
Additional:
* 
Earthshock's slow is ignored by Shukuchi.
* Ursa can be kited with Shukuchi and his burst damage will be negated with Time Lapse as long as Weaver survives it.
* The Swarm breaks Ursa's Blink Dagger, forcing him to deal with the beetles.
Weaver
* A well-timed Gust will prevent Weaver from escaping, and a silenced Weaver usually dies very quickly.
* Weaver gains a lot of armor, which is bypassed by Marksmanship.
Additional:
* A well-timed 
Gust followed by 
Frost Arrows will prevent Weaver from escaping with Shukuchi. A Weaver silenced for more than 3 seconds usually dies very quickly.
* Due to her high attack speed, Drow Ranger can easily kill The Swarm beetles.
Legion Commander
* Drow Ranger's low mobility and lack of defensive abilities make her an easy gank target in the early to mid-game.
* A Dueling Drow Ranger will lose her precious 
Marksmanship, reduce her damage output significantly, and will more likely lose that Duel.
Legion Commander
* Heroes that cannot move in fights such as a Dueling Legion Commander or anyone channeling a spell like 
Bane, Pudge, or 
Enigma are easy Sacred Arrow targets.
Legion Commander
* Heroes that can protect or dispel stunned allies such as Legion Commander, Outworld Destroyer, Shadow Demon and Oracle can reduce the effectiveness of Sacred Arrow.
Weaver
* 
Spiked Carapace allows Nyx to get an easy long-duration stun on Weaver once he uses Shukuchi, and then he can follow up with 
Impale.
* 
Vendetta works as a great setup for both Impale and Spiked Carapace and can deal decent damage to Weaver. Additionally he can neutralize The Swarm beetles due to his invisibility duration.
Legion Commander
* Duel's long duration prevents Nyx Assassin escaping from Vendetta. With Aghanim's Scepter, she can also bypass Spiked Carapace.
Weaver
* Silences and other types of lockdown that prevent Weaver from using his spells: Silencer, Riki, Lion, Legion Commander, Shadow Shaman, Bane.
Legion Commander
* Heroes that can disable or silence Silencer for a long time, such as Bane and Legion Commander, can lock down Silencer while their allies put him down.
Legion Commander
* 
Tethered heroes are much harder for Legion Commander to kill in Duels.
* 
Relocate can cancel Duels and save allies.
Legion Commander
* Duel is very effective against Io due to its low health and armor.
Weaver
* Weaver relies on
Shukuchi to escape and kite enemy heroes. Slardar's Corrosive Haze lowers armor and reveals Weaver, who is already a very frail target.
Linken's Sphere, Corrosive Haze can be used to pop the spell block, additionally the level 25 undispellable talent will prevent Weaver from removing Corrosive Haze with 
Time Lapse, allowing allied heroes to use their abilities on Weaver.
Corrosive Haze lowers armor and reveals Weaver during Shukuchi, who is already a frail target. In addition, Weaver usually builds 
Linken's Sphere, and 
Corrosive Haze can be used to "pop" the spell block. His level 25 talent can also make Corrosive Haze undispellable by Time Lapse, which puts Weaver in an even worse situation. 
Guardian Sprint can dodge Weaver's bugs with the movement speed bonus.
* Weaver usually builds
Additional:
*
*
Legion Commander
* With armor items like
Solar Crest or 
Assault Cuirass combined with Bash of the Deep, Slardar can easily tank the 
Duel, If not dueled himself, he can drop 
Legion Commander's armor during duel and/or buff his teammate and save them, leaving her only the choice of dueling supports which can also be saved with fast Blink into Slithereen Crush.
