Timbersaw
* Timbersaw's physical survivability revolves around 
Reactive Armor, which is largely ignored by Fury Swipes due to the extreme amounts of damage it does in a very few number of attacks.
* Timbersaw's burst damage will not do much against Enrage, although he could easily use 
Timber Chain to escape, wasting the duration of it.
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
Timbersaw
* Nether Ward can punish Timbersaw, as Timbersaw is a spell-caster with low cooldowns. Furthermore, Timbersaw usually appears in the midst of battle, placing himself in range of Nether Ward's Mana Flares.
* Timbersaw has no stuns or silences to stop Life Drain. Since all of Pugna's Spells are magical, the damage can be devastating to Timbersaw.
* Decrepify can further increase all the magical damage done to Timbersaw, bypassing the enhanced physical resistance he can get from Reactive Armor.
Additional:
* 
Nether Ward can punish Timbersaw, as Timbersaw is a spell-caster with low cooldowns. Furthermore, Timbersaw usually appears in the midst of battle, placing himself in range of Nether Ward's Mana Flares.
* Timbersaw has no stuns or silences to stop 
Life Drain. Since all of Pugna's Spells are magical, the damage can be devastating to Timbersaw, especially when combined with 
Decrepify.
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
Timbersaw
* Magical burst damage is Timbersaw's weakness, and Ancient Seal not only amplifies it but also prevents him from using Timber Chain to escape for up to 6 seconds.
* He generally doesn't build early items to deal with silences.
* Reactive Armor does not trigger on magic damage or spells, meaning that even a 
Pipe of Insight won't give him the massive sustain he normally gets from attacks.
Additional:
* Skywrath Mage's long range and low cooldown magic damage spells can easily harass Timbersaw out of lane.
* 
Ancient Seal is not only a long lasting silence, (one of Timbersaw's biggest weaknesses) but it also makes him even more vulnerable to magical burst damage.
Legion Commander
* 
Mystic Flare can easily burst down Legion Commander while she is Dueling.
Timbersaw
* 
Rolling Thunder's stuns make it harder for Timbersaw to escape with Timber Chain.
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.
Timbersaw
* Zeus deals enormous amounts of magic damage, being one of the best heroes to burst down Timbersaw early in the game.
* 
Lightning Bolt's mini-stun can stop Timbersaw's from escaping a fight with Timber Chain.
Additional:
* Reactive Armor will not trigger from Zeus's spells or protect Timbersaw from their damage.
* Early game Timbersaw's strength is average and Zeus can heavily aid in bursting him down.
* Late game, if Timbersaw has built a lot of HP items, Zeus's passive Static Field will be more effective at chipping away Timbersaw's large HP pool.
* A Timbersaw who builds Pipe of Insight will be much more difficult to kill, as Zeus has no way to hold Timbersaw down, but Timbersaw will have less armor, mana, and damage than normal if he buys this item early game just to counter Zeus.
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
Timbersaw
* 
Brain Sap's pure damage ignores stacks of Reactive Armor.
* 
Nightmare prevents Timbersaw from using Timber Chain, setting him up for chain stuns and burst damage.
* 
Enfeeble highly reduces regeneration granted by reactive armor.
* 
Fiend's Grip immobilizes Timbersaw and drains his low mana pool, preventing escape afterwards. It also pierces 
Black King Bar.
* Bane's multiple disables often force Timbersaw or his teammates to spend gold on a 
Linken's Sphere.
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.
Legion Commander
* Heroes with strong dispels can dispel Bane's disables from their allies: 
Oracle, 
Legion Commander, 
Omniknight.
Timbersaw
* 
Cold Snap can prevent Timbersaw from using both Timber Chain and Chakram due to the frequent stuns interrupting the lengthy cast animations, as well as stopping him mid-chain. This can negate Timbersaw's attempts to escape or dole out extra ability damage.
* Later in the game, Invoker's heavy magical and pure damage can be difficult to avoid, meaning Timbersaw's armor is less useful.
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.
Timbersaw
* Heroes that withstand damage like 
Timbersaw, 
Bristleback, 
Dragon Knight and others will have their durability largely reduced when hit by an Ice Blast due to the risk of shattering.
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
* 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.
Timbersaw
* Rupture and Blood Rite locks down Timbersaw, preventing him from escaping with Timber Chain. However, Timbersaw may reflect a good deal of damage with 
Blade Mail.
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.
Timbersaw
* 
Hex greatly reduces Timbersaw's mobility.
* The stun and damage over time from 
Shackles mitigates Reactive Armor's HP and armor regen.
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
* Solar Guardian can save allies who are being dueled and will interrupt her Duel initiation.
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.
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.
Legion Commander
* Earthshaker's AoE stuns can save ally against Duel, forcing Legion Commander to spend Aghanim's Scepter or Black King Bar.
Timbersaw
* Bramble Maze prevents Timbersaw from Timber Chaining away without getting rooted.
* Cursed Crown can still catch Timbersaw if he Timber Chains away.
* Reactive Armor offers little protection against Dark Willow's high magical damage.
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
* 
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.
Timbersaw
* 
Ball Lightning makes Storm Spirit a target difficult to chase, even for a hero as mobile as Timbersaw.
* The magical damage from 
Static Remnant and 
Overload together with Storm Spirit's high mobility allows Storm Spirit to jump on Timbersaw and burst him down, even if he tries to escape.
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.
Timbersaw
* 
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.
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.
Timbersaw
* Timbersaw relies heavily on his abilities so Phantom's Embrace's silence makes it more difficult for him.
* Timbersaw cannot use 
Return Chakram or attack the phantom during Phantom's Embrace, forcing him to take full damage and refreshes Phantom's Embrace's cooldown.
Additional:
* Timbersaw is completely powerless against 
Phantom's Embrace if 
Chakram is out.
Timbersaw
* 
Searing Chains prevents usage of Timber Chain.
* Timbersaw is vulnerable to magical burst damage, which Ember Spirit provides with 
Fire Remnant and 
Flame Guard.
* Timbersaw's abilities deal pure damage, thus they cannot remove Flame Guard.
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.
Timbersaw
* 
Infernal Blade deals scaling damage and is useful against high HP targets such as Timbersaw.
* Timbersaw is extremely reliant on his abilities to be effective during a team fight - both for mobility, damage and crowd control. Timbersaw offers very little, impactful right-click damage, and thus 
Doom is particularly crippling against him.
* Additionally, when Doom chooses the {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent} talent, Doom disables Reactive Armor, which effectively removes the durability which Timbersaw is commonly known for.
Additional:
* Doom shuts down Timbersaw completely, negating his mobility and preventing him from doing any damage. It also breaks Reactive Armor's passive bonuses from Aghanim's Scepter.
* Infernal Blade can stun Timbersaw several times in a fight, potentially interrupting Timber Chain. Also it's useful since Timbersaw has high HP due to the damage scales based on max HP.
Timbersaw
* Reactive Armor's armor increase does not affects Muerta's Pierce the Veil despite Muerta often building high attack speed.
* Muerta's 
Dead Shot destroys trees preventing Timbersaw from escaping with his Timber Chain.
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.
Timbersaw
* Templar Assassin 
Meld`s ability will break Timbersaw's armor, which makes it very easy to break through and not feel his Reactive Armor, which will allow the team to kill Timbersaw quickly, or drive him out of the fight.
* Templar Assassin's 
Refraction ability gives her the ability to avoid damage from 
Whirling Death, which will give her the ability to deal Timbersaw more damage than he will deal.
Additional:
* Templar Assassin Meld`s ability will break Timbersaw's armor, which makes it very easy to break through and not feel his Reactive Armor, which will allow the team to kill Timbersaw quickly, or drive him out of the fight.
* Templar Assassin's Refraction ability gives her the ability to avoid damage from Whirling Death, which will give her the ability to deal Timbersaw more damage than he will deal. However, he may easily burn through Refraction with Chakram.
Timbersaw
* 
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.
Timbersaw
* Heroes who are melee but cannot fight back against Eclipse will really struggle with Luna: 
Monkey King, 
Alchemist, Timbersaw.
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.
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
* 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.
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.
Timbersaw
* Heroes that have escape abilities (such as 
Queen of Pain, 
Storm Spirit or Timbersaw) can be either nullified by Reaper's Scythe or a complimentary item for Necrophos (like 
Rod of Atos or 
Scythe of Vyse). If Necrophos is quick enough and enters range, they can quickly, if not instantly, die if they are not quick enough.
Additional:
* 
Heartstopper Aura effectively negates Timbersaw's large HP pool as well as HP regen.
* 
Death Pulse together with health and mana regeneration from killed creeps helps Necrophos and his teammates survive Timbersaw's burst damage.
* As a tanky hero that stays in the middle of teamfights, Timbersaw is an easy target for 
Reaper's Scythe.
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".
Timbersaw
* Timbersaw has a difficult time against magical and pure damage: 
Lina, 
Leshrac, 
Enchantress, Queen of Pain
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.
Timbersaw
* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, Storm Spirit, 
Ember Spirit, 
Lycan, 
Bloodseeker, 
Anti-Mage, Timbersaw.
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.
Legion Commander
* Magnetic Field prevents Legion Commander from getting wins with Duel.
Additional:
* 
Magnetic Field prevents Legion Commander from easily gaining wins with Duel.
Legion Commander
* Heroes who rely on summons will see them destroyed easily by Overwhelming Odds: Lycan, 
Arc Warden, 
Warlock, 
Chen
Timbersaw
* Timbersaw is heavily reliant on his abilities for damage and escape, allowing Silencer to effectively disable him and make him useless in both team fights and 1v1 scenarios.
Additional:
* 
Arcane Curse deals repeated stacks of damage to Timbersaw because he relies on constantly using his abilities.
* 
Glaives of Wisdom deals pure damage and when cast manually, nearby creeps will not attack silencer, making it an effective harassment tool. The intelligence steal is also especially potent against Timbersaw since he often uses up all of his mana throughout the entire game.
* Although Last Word takes a while to trigger, it will break Timbersaw's ability combo and can be used to silence him.
* 
Global Silence will silence Timbersaw no matter where he is on the map. This can be used to help allies get a kill on him, or prevent Timbersaw from killing someone.
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
* 
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.
Timbersaw
* Heroes who rely on abilities to deal damage (e.g. Timbersaw, 
Tinker) can fight a Razor even after Static Link.
Additional:
* Razor deals mostly physical damage towards the later game, and Timbersaw is also very mobile, making him a difficult kill to earn.
* Timbersaw rarely resorts to attacks, thus does not suffer when his damage is stolen with Static Link.
Timbersaw
* Timbersaw's abilities combos all deal magical and pure damage, completely ignoring Terrorblade's high base armor and clearing his illusions very quickly due to the AoE damage.
* Reactive Armor negates most of Terrorblade's damage against Timbersaw, and its high health regeneration and armor bonuses can help Timbersaw survive after Terrorblade has used 
Sunder on him.
Additional:
* Timbersaw can take down Terrorblade's illusions with his area damage burst.
* Reactive Armor plus another armor item reduce much of Terrorblade's damage.
Legion Commander
* Duel's long duration prevents Terrorblade from swapping his health with Sunder.
* Overwhelming Odds deals high damage to Terrorblade's illusions.
Timbersaw
* With Timber Chain, Timbersaw can slow, catch up with, or escape from Chen and his creeps.
* Chakram and 
Flamethrower from 
Aghanim's Shard can clear Chen's creeps and slow him.
* Attacks from multiple creeps will quickly build Reactive Armor stacks, making attacks of Chen and his creeps only tickle Timbersaw.
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.
Timbersaw
* Whirling Death deals damage while also reducing {Show:A|Timbersaw|Whirling Death|value4} of Bristleback's strength, making him less tanky.
* Reactive Armor can sustain through multiple Viscous Nasal Goo and Quill Spray stacks.
* Timber Chain makes it hard for Bristleback to slow down Timbersaw even with Viscous Nasal Goo.
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.
Timbersaw
* The percentage-based primary-attribute reduction effect of Whirling Death can be devastating for Pudge due to his high strength gain through Flesh Heap.
* Reactive Armor's health regeneration and common itemization for magic resistance and durability makes Timbersaw a poor target for Pudge.
* Timber Chain's high mobility makes it difficult for Pudge to hook or deal much Rot damage to Timbersaw.
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.
Timbersaw
* Reactive Armor prevents Broodmother's spiderlings from being able to effectively harass Timbersaw in the lane.
* Timber Chain's high mobility makes Silken Bola's slow irrelevant, unless Broodmother already bought her Orchid.
* Silken Bola's miss chance doesnt affect Rizzrack that much because he does not rely on his autoattacks much.
* 
Lotus Orb items for Timbersaw make Silken Bola useless.
* Timbersaw's abilities can destroy any trees that Broodmother attempts to hide in and his AoE abilities can quickly clear her Spiderlings.
Additional:
* Spiderlings deal almost no damage against Reactive Armor. They also die quickly from Timbersaw's AoE abilities.
* Broodmother has no mobility ability except the movement speed buff from 
Spin Web, allowing Timbersaw to easily escape her 
Silken Bola with Timber Chain.
* Timbersaw's tree-cutting abilities make it difficult for Broodmother to hide, especially near the edges of the map.
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.
Timbersaw
* All Timbersaw's abilities deal AoE pure damage and can easily deal with Phantom Lancer's illusions.
* Reactive Armor highly negates Phantom Lancer's physical damage, making him having a hard time killing Timbersaw.
Additional:
* Phantom Lancer's lack of burst damage and constant attacks will increase Reactive Armor to max level immediately.
* Coupled with Timber Chain, it makes an easy escape and almost impossible for Timbersaw to be killed by Phantom Lancer.
* Whirling Death and Chakram can instantly destroy large groups of illusions, negating Phantom Lancer's advantage, although Phantom Lancer usually builds 
Diffusal Blade. It can be a problem in late game.
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.
Timbersaw
* Strong area damage, particularly from Whirling Death and Chakram, lets Timbersaw clear out illusions quickly.
* Whirling Death directly reduces Strength from both Chaos Knight and his Phantasm illusions, reducing both the damage output and raw health that the hero relies on.
* Reactive Armor quickly builds stacks against Phantasm illusions, making Timbersaw harder to kill.
Additional:
* Reactive Armor helps Timbersaw to endure the damage from 
Chaos Bolt and 
Reality Rift combo.
* Timbersaw's large amount of pure damage AoE nukes clears Chaos Knight's illusions quickly, drastically reducing his damage.
Legion Commander
* Heroes with strong area damage to destroy Phantasm illusions: Axe, Ember Spirit, Legion Commander, Phoenix
Timbersaw
* All of Timbersaw's spells deal AoE damage, killing Lycan's summons very quickly.
* Reactive Armor will gain stacks quickly because of Lycan's summons.
Legion Commander
* Heroes who rely on summons will see them destroyed easily by Overwhelming Odds: Lycan, Arc Warden, Warlock, Chen
Timbersaw
* Special mention to Timbersaw as he has a way to deal with Axe in the laning stage, but still needs to be careful about Berserker's Call stun, the pure damage from Counter Helix and Culling Blade finishing him off before he can escape or heal from his passive.
Additional:
* Whirling Death reduces Axe's strength by 15%, which makes him less durable, especially from early game. It's also stackable.
* Blade Mail are not effective against attribute changes, and Timber Chain can wait out Blade Mail's duration to wear off.
* Reactive Armor makes it harder for Axe to finish off Timbersaw with 
Culling Blade.
* Chakram disarms Timbersaw, which makes Axe's 
Counter Helix useless against him.
* All Timbersaw skills deal pure damage, which bypass Axe's high armor or bonus armor from 
Berserker's Call.
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.
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.
Legion Commander
* Press the Attack dispels Flaming Lasso.
* Batrider is unlikely to win a Duel in any stage of the game.
Timbersaw
* Timbersaw’s reliance on nearby trees means he’ll usually be close to Hoodwink.
* More significantly, Timbersaw's tree destroying abilities cut off Hoodwink's escape options, passive and easily foil 
Acorn Shot or 
Bushwhack combos.
* While channeling 
Sharpshooter, Timbersaw can simply sit his Chakram on top of her and unleash his full combo, forcing her to cancel and disengage.
* Timber Chain can be used to dodge Sharpshooter.
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
Timbersaw
* All three of Timbersaw’s abilities give him an easy way out of Sprout, and can also destroy nearby trees so Nature's Prophet can’t spawn Treants.
* If Prophet tries to escape with a self Sprout/Teleport, Timbersaw can easily cut down all its trees to get to him and deal increased Whirling Death damage as well.
* Chakram heavily discourages teleports.
* Timbersaw is quite well suited to clearing massive waves of Treants almost instantly with all of his area of effect pure damage abilities, preventing Nature's Prophet from pushing.
* Treants can give Reactive Armor many charges quite quickly.

* Timbersaw can easily cut down trees from 
Sprout, making it very difficult for Nature's Prophet to teleport away or trap enemies.
* Timbersaw's abilities quickly clear out treants.
* Reactive Armor negates most of the damage of Nature's Prophet's treants, and Timbersaw can often allow himself to be attacked in order to heal himself.
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
* 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.
Timbersaw
* Timbersaw is often too mobile and durable for Gyrocopter to bring down with his area attacks.
Timbersaw
* Reactive Armor is very effective against Beastmaster's summons during laning stage and entire game.
* Timbersaw can quickly clear Beastmaster's summons with his nukes.
* Lotus Orb item for Timbersaw can releases roar from the target position, stunning and damaging Beastmaster and knocking away, damaging and slowing allies that stand on the way.
Timbersaw
* Timbersaw's pure damage will kill Dragon Knight surprisingly fast, especially if he gets caught in a bad position while laning.
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.
Timbersaw
* Timbersaw Defeats Kunkka on the center line, due to the fact that he has a huge resistance to physical damage by Reactive Armor, which is why 
Tidebringer almost does not break through Timbersaw, and due to Whirling Death Timbersaw can very much break through Kunkka and force him to leave the line, or spend money on 
Tango.
Additional:
* Timbersaw easily beats Kunkka on the midlane, due to the fact that he has huge physical damage resistance from Reactive Armor, which is why Tidebringer almost does not break through Timbersaw, and due to Whirling Death and Kunkka being a strength hero, Timbersaw can very much break through Kunkka and force him to leave the lane, or spend money on Tango.
Timbersaw
* Reactive Armor helps Timbersaw sustain harassment from 
Stifling Dagger.
* Phantom Assassin has a moderate health pool and usually appears in the front line of battle, making her vulnerable to Timbersaw's pure burst damage output.
* Timbersaw can easily escape from Phantom Assassin thanks to his Timber Chain.
Additional:
* Reactive Armor helps Timbersaw sustain harassment from Stifling Dagger, as well as ganking attempts.
* Phantom Assassin is a hero with moderate HP pool, and usually appears in the front line of battle. Because 
Blur does nothing against spells, she is vulnerable to Timbersaw's skills.
* Timbersaw can easily escape from Phantom Assassin thanks to his Timber Chain.
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.
Legion Commander
* Duel's long duration prevents Nyx Assassin escaping from 
Vendetta. With Aghanim's Scepter, she can also bypass 
Spiked Carapace.
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
* Duel pierces spell immunity and forces him to attack Legion Commander, making him unable to use 
Omnislash.
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).
Timbersaw
* Timbersaw's innate durability provided by Reactive Armor is very hard to deal with as Naga Siren as she mostly relies on sustained damage rather than burst damage unless if she is played as Nuker.
* Timbersaw's high pure damage and low-cooldown area-of-effect nukes which are Whirling Death, Timber Chain, Chakram and Flamethrower from Aghanim's Shard can also destroy Naga Siren's illusions very fast.
* Timbersaw is a common Lotus Orb wielder which allows him to reflect 
Ensnare back at Naga SIren.
Legion Commander
* Heroes who rely on illusions will see them destroyed easily by Overwhelming Odds: Phantom Lancer, Chaos Knight, Terrorblade, Naga Siren
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
* 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
* Heroes who rely on summons will see them destroyed easily by Overwhelming Odds: Lycan, Arc Warden, Warlock, Chen
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.
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
* Heroes rely on their debuff to control the opponent will have a hard time against Press the Attack: Venomancer, Earth Spirit, Ogre Magi
Timbersaw
* Reactive Armor makes Timbersaw very effective against heroes that control a lot of units, such as 
Broodmother, Lycan and 
Undying.
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.
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.
Timbersaw
* Timbersaw: Lone Druid will have a hard time dealing with Timbersaw due to his tankiness and high Armor from Reactive Armor
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
Timbersaw
* Timbersaw has a difficult time against magical and pure damage: Lina, Leshrac, Enchantress, Queen of Pain
Timbersaw
* The burst damage from Timbersaw's abilities is more than enough to deal with Enchantress and her creeps.
* Timbersaw doesn't rely on his physical attacks, which makes Untouchable useless against him.
* Timber Chain can close the gap between them and minimize damage from Impetus.
* Bear in mind, however, that Timber Chain can also work against Timbersaw if used to escape and that Impetus can ignore Reactive Armor if Enchantress is not a primary target for Timbersaw or if he is disabled.
* Timbersaw is a common wielder of Lotus Orb, which will allow him to reflect Enchant back at Enchantress and dispel most debuffs as well.
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
Timbersaw
* Timbersaw's low cooldown and low mana cost abilities destroys the trees that Monkey King depends on.
* Timber Chain allows Timbersaw to escape Wukong's Command.
Additional:
* Timbersaw can easily cut down the tree that Monkey King is standing on, stunning him for a lengthy period.
* Timbersaw can use Timber Chain to easily escape 
Wukong's Command and 
Primal Spring's slow.
* However, when facing Monkey King mid, Timbersaw might get harassed out of the lane because of 
Jingu Mastery.
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
Timbersaw
* Timbersaw can use his plethora of tree cutting abilities to level entire sections of the forest, making hiding in the trees more difficult for Treant Protector and his team.
* Timbersaw can easily cut down Treant Protector's 
Eyes In The Forest once his team has detection. He may even do it unknowingly due to the sheer destructive and chaotic nature of his abilities.
Additional:
* Not only are all of Timbersaw's active abilities capable of cutting down trees, but Whirling Death and Timber Chain also require it to be effective, counteracting both Treant Protector's Nature's Guise and Eyes in the Forest abilities.
Legion Commander
* Troll Warlord's melee bash and high attack speed can often help him and his allies win Duels against Legion Commander.
Timbersaw
* Timber Chain can kite Troll Warlord extremely effectively.
* Whirling Death and Chakram deals lots of damage to Troll Warlord.
* Reactive Armor makes Timbersaw extremely resilient to Troll's attack damage and extreme attack speed, especially during Battle Trance.
Timbersaw
* Timbersaw has a difficult time against magical and pure damage: Lina, Leshrac, Enchantress, Queen of Pain
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.
Timbersaw
* Heroes who build mana boosting items but have low mana regeneration are especially vulnerable against Mana Break and Mana Void: Timbersaw, Slark, 
Shadow Fiend, 
Clinkz, Bristleback 
Nyx Assassin, 
Magnus
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.
Timbersaw
* In general, Timbersaw struggles against highly mobile heroes that can avoid his abilities: Puck, Weaver, Ember Spirit and others.
Legion Commander
* Duel's long duration prevents Weaver from activating Time Lapse or escaping with 
Shukuchi.
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
* 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.
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.
Timbersaw
* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, 
Dark Willow, 
Enigma, Invoker, 
Pugna, 
Skywrath Mage, Tinker, Zeus, Oracle.
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
* 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.
Timbersaw
* Heroes who are not easily crippled by Fate's Edict or Fortune's End, such as Timbersaw, or those who can dispel them, such as Phantom Lancer, can kill Oracle unhindered.
Legion Commander
* Heroes with long disables, like Lion, 
Night Stalker, or Legion Commander, can prevent Oracle from using spells or items.
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.
Timbersaw
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, Earth Spirit, Faceless Void, Magnus, 
Mirana, Monkey King, 
Morphling, 
Pangolier, Phantom Assassin, Phoenix, Puck, Queen of Pain, Riki, 
Sand King, Spirit Breaker, Timbersaw, Tusk.
Timbersaw
* Heroes with AoE abilities will hit Slark in Shadow Dance: Lina, 
Jakiro, 
Underlord, Leshrac, 
Dark Seer, 
Earthshaker, Timbersaw, Crystal Maiden.
Additional:
* Timbersaw can use Chakram as a scouting tool to find Slark if he tries to 
Pounce into the trees.
* None of Timbersaw's abilities require a target to be cast, allowing him to hit Slark inside 
Shadow Dance.
* Reactive Armor can be effective protection against a Slark who attacks quickly, since the strong armor and health regen cannot be stolen by 
Essence Shift.
* Timber Chain makes Timbersaw very mobile, meaning he is among the very few heroes who can actually give chase to a fleeing Slark.
Timbersaw
* All Tinker's damage is magic/pure and completely ignores Timbersaw's Reactive Armor.
* Timbersaw very rarely builds Black King Bar, making him very vulnerable if Tinker builds Scythe of Vyse.
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
Timbersaw
* Timbersaw's ability to destroy trees can be a serious problem for some heroes that use them, as either a way of enhancing their spells like Treant Protector, or heroes that tend to hide inside of them like Tinker and Monkey King.
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.
Timbersaw
* Because Timbersaw relies heavily on his spells to deal damage, Silence can easily disable him in a team fight.
* Exorcism's spirits do not count as regular attacks, and will not add stacks of Reactive Armor.
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.
Timbersaw
* 
Viper Strike prevents Timbersaw from gaining stacks on Reactive Armor.
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.
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.
Timbersaw
* Because multiple Meepos tend to clump up, they present an easy target for Timbersaw's many area abilities.
* Although be careful since Timbersaw cannot use Timber Chain to escape if rooted from 
Earthbind.
Timbersaw
* Timbersaw has a difficult time against magical and pure damage: Lina, Leshrac, Enchantress, Queen of Pain
Timbersaw
* Heroes that can close the gap can easily chase Lina down, such as Timbersaw with Timber Chain and Anti-Mage with Blink.
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.
Timbersaw
* Timbersaw relies on dealing massive amounts of pure damage, making Cold Embrace a good setup for his nukes.
* If he has Reactive Armor stacks, Timbersaw can tank the damage from his allies if he is targeted by Winter's Curse. If he's not the target, Timbersaw's abysmal attack damage will contribute next to nothing when he is cursed to attack an ally.
* As Timbersaw commonly buys Lotus Orb, he can use it to reflect Winter's Curse back to Winter Wyvern if she uses it impulsively on him or any other hero while affected by it.
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.
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.
Timbersaw
* Reactive Armor will quickly stack up from Familiar attacks, making Timbersaw hard to kill.
* Visage's low mobility makes it easy for Timbersaw to line up his abilities.
Timbersaw
* Arcane Orb's pure damage ignores Timbersaw's
Reactive Armor.
Timber Chain, preventing him from escaping.
Arcane Orb deals constant pure damage, which bypasses Timbersaw's Reactive Armor.
Sanity's Eclipse can hit targets inside 
Astral Imprisonment, which helps Outworld Destroyer finish off Timbersaw before he escapes with Timber Chain. It can also drain his mana, limiting his ability to escape should he survive.
* Astral Imprisonment, if timed correctly, can interrupt
Additional:
*
*
Legion Commander
*
Astral Imprisonment prevents Legion Commander from killing her opponents in Duels.
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.
Additional:
* Outworld Destroyer can save an ally hero caught by
