* Nature's Prophet has no innate way to deal with Gravekeeper's Cloak or kill {U:Familiar}s effectively.
* Familiars can fly over the trees created by Sprout. They can also use Stone Form when Nature's Prophet is trying to use Teleportation.
* Aghanim's Shard upgraded Stone Form alow allows Visage himself to stun Nature's Prophet whenever he is trying to use Teleportation.
* Aghanim's Scepter gives Visage Silent as the Grave ability, which allows him and his {U:Familiar}s to either escape from Nature's Prophet or give him a surprise attack.
Additional:
* Nature's Prophet has no natural method of dealing with Gravekeeper's Cloak and Familiars.
* Familiar's low base attack time can chip away Nature Prophet's health.
* Familiar's Stone Form destroys trees created by Sprout.
* Familiars can scout woods and foggy areas where Nature's Prophet is trying to use Teleportation.

* 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.

* Firestorm makes quick work of Treants and Atrophy Aura gives him temporary damage for every Treant killed.
* Pit of Malice can stop Teleportation channeling.
* Atrophy Aura greatly reduces Nature's Prophet's damage and he has no other good way to deal damage.
* Fiend's Gate can counter split-pushing, which is something that Nature's Prophet relies on a lot. Fiend's Gate can also be used to either escape from Nature's Prophet or to prepare an ambush on Nature's Prophet, and outside from Nature's Wrath, Nature's Prophet has no other ways to intercept arrivals with Fiend's Gate.

* 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.

* Clockwerk's long range initiation and catch makes it incredibly difficult for Nature's Prophet to split push and show on the map alone.
* Rocket Flare can be used to scout Nature's Prophet if he is hiding in the forest, and can provide vision inside of Sprout.

* 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.

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

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

* Starbreaker and Celestial Hammer does high AoE damage which easily clears {U:Treant}, shutting down most of Nature's Prophets damage and pushing power.
* Dawnbreaker can teleport to deal with split-pushing Nature's Prophet and rejoin her team with Solar Guardian when they require it.
* Since Starbreaker clears trees in its path followed by a stun at the end Nature's Prophet will be unable to escape the dangerous situation by using Sprout on himself and teleporting away with either Teleportation or Town Portal Scroll.
Additional:
* Starbreaker and Celestial Hammer does high AoE damage which easily clears {U:Treant}, shutting down most of Nature's Prophets damage and pushing power.
* Dawnbreaker can teleport to deal with split-pushing Nature's Prophet and rejoin her team with Solar Guardian when they require it.
* Since Starbreaker clears trees in its path followed by a stun at the end Nature's Prophet will be unable to escape the dangerous situation by using Sprout on himself and teleporting away with either Teleportation or Town Portal Scroll.

* Solar Guardian can save allies who are being dueled and will interrupt her Duel initiation.

* Broodmother, Nature's Prophet, Phantom Lancer by their nature offer very good target for Splinter Blast and Winter's Curse.

* 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.

* Nature's Prophet is heavily countered by Meepo, not only Meepo can kill the treants with a single Poof, but he can also stop Nature's Prophet from using Teleportation, and can gain vision inside Sprout.

Additional:
* Meepo can net Nature's Prophet's treants with Earthbind and then Poof them, putting an end to his pushing.
* Skilled Meepos can rival and even exceed Nature's Prophet's global presence by combining Poof with Boots of Travel, meaning that he can not only stop his push, but also can kill him if he is not careful.

* 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.

* Heroes who can provide True Sight or semi-reveal enemy heroes as Nature's Prophet is prone to buying Shadow Blade: Bounty Hunter, Slardar, Spectre, Zeus, Spirit Breaker.

* 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.

* Heroes who have summons, which can be quickly cleared by his powerful area of effect skill: Nature's Prophet, Enigma, Lycan

* 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.

* Naga Siren is a natural split-pusher. With Rip Tide, she will easily out-push Nature's Prophet, farming his treants in the process.
* Ensnare prevents Teleportation. Even if he hides inside Sprout, Song of the Siren lasts long enough to prevent him from escaping.
Additional:
* Naga Siren is a natural split-pusher. With a Radiance equipped, she will easily keep the lanes pushed out, therefore keeping backdoor protection enabled and preventing Nature's Prophet from dealing building damage.
* Ensnare can prevent Teleportation. Aghanim's Scepter upgraded Ensnare can also affect Nature's Prophet even if he is spell immune. And Reel In from Aghanim's Scepter can also be used to separate Nature's Prophet from his treant and bring him close to Naga Siren and her team to burst him down.
* Song of the Siren will stop Nature's Prophet from escaping even if he has hidden inside of Sprout. Aghanim's Shard upgraded Song of the Siren can also heal her allies and save them from Nature's Prophet.

* Song of the Siren lasts long enough to prevent a successful Duel (but only if Naga wasn't the target).

* Heroes who can provide True Sight or semi-reveal enemy heroes as Nature's Prophet is prone to buying Shadow Blade: Bounty Hunter, Slardar, Spectre, Zeus, Spirit Breaker.

* 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

* 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.

* 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.

* 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.

* Mana Shield makes Medusa very hard to take down in Duels.
* Stone Gaze stops Legion Commander from Dueling altogether, regardless of who she targets.

* Astral Spirit can give Elder Titan a lot of damage and movement speed if Nature's Prophet sends all of his Treants together.

* Earth Splitter can clear Nature's Prophet's Treants effectively.

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

* Ember Spirit can easily deal with Nature's Call by using his Flame Guard and with Battle Fury. He also has multiple ways of escaping Sprout. Additionally, Ember Spirit can break Sprout's trees with Activate Fire Remnant and interrupt Teleportation with Searing Chains.
Additional:
* Sleight of Fist with Battle Fury deals a lot of damage to Nature's Prophet's team if they stand close to his Treants, as well as killing all the Treants with ease.
* Ember Spirit with Fire Remnant and Boots of Travel can be very active around the map, which enables him to quickly teleport and defend the objective Nature's Prophet is attacking whenever he tries to push.

* Shadow Shaman's Mass Serpent Ward together with Ether Shock can easily kill lots of Treants if played defensively.
* Hex and Shackles can disrupt Nature's Prophet's escape attempts with Teleportation.
Additional:

* 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.

* 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.

* Undying's Tombstone will cheerfully chew through treants, incidentally netting you some extra income during fights.
* The above interaction tends to ensure that skirmishes are heavily populated with units, thereby buffing Soul Rip

* Sand King's Caustic Finale combined with Sand Storm will kill Treants easily.
* Sand King can interrupt Teleportation with Burrowstrike, even through Sprout.
Additional:
* With Caustic Finale, Sand King can easily kill the treants from Nature's Call.

* Sprout can't stop her to Rebound.
* Treants can be used as targets for Rebound and Dispose as well.

* Mystic Flare can easily burst down Legion Commander while she is Dueling.

* Jakiro's skill arsenal can ruin Nature's Prophet's gameplay: Dual Breath and Liquid Fire can clear treants from Nature's Call while simultaneously slowing Nature's Prophet, Ice Path can disrupt Nature's Prophet's escaping attempt with Teleportation, and Macropyre can easily clear treants from Nature's Call.
* Jakiro is a common Hurricane Pike wielder, which allows him to escape from Sprout.
Additional:
* Jakiro's Macropyre can help him to escape from Sprout and quickly clears Treants.
* Jakiro can disrupt Nature's Prophet's escape attempt with Sprout and Teleportation by using Ice Path.

* If Shadow Fiend buys Boots of Travel and Shadow Blade, he can counteract Nature's Prophet's split-push.

* 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.
Additional:
* Timbersaw can easily cut down trees from Sprout, making it very difficult for Nature's Prophet to teleport away or trap enemies.

* Shadow Wave will heal an ally caught in a Duel, as well as dealing damage to Legion Commander.

* Heroes who lack burst damage will have a hard time against Mars: Phantom Lancer, Nature's Prophet, Lich.

* 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.

* Even though Nature's Prophet can evade all of Luna's abilities with Shadow Blade, a smart Luna will always buy Dust of Appearance to provide vision on Nature's Prophet to her and her team.

* 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.

* 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

* 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".

* Heroes that rely on summons will suffer against Ion Shell, which kills them very quickly: Beastmaster, Broodmother, Enigma, Nature's Prophet, Visage, Warlock, Wraith King.

* 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.

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.

* Similarly, heroes with low cooldown teleports can be afraid to split push against X Marks the Spot, such as Tinker and Nature's Prophet.

* 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.

* Pounce also stops Nature's Prophet's Teleportation.

* Mass summoning heroes: Broodmother, Nature's Prophet and Enigma all have summons Puck can clear with Illusory Orb and Waning Rift instantly, due to their summons having low health.

* Heroes who rely on illusions and spawns (Chaos Knight, Beastmaster, Nature's Prophet, Enigma etc.).

* Heroes who can hide the Dueled target (Outworld Destroyer, Shadow Demon, Tusk, Phoenix with Aghanim's Scepter etc).

* Sprout cannot protect Nature's Prophet if Broodmother puts down a web.
* Nature's Prophet's low mobility means he is defenseless against Silken Bola.
* Spiderlings can absorb much of the damage from Wrath of Nature.
* Aghanim's Scepter gives Broodmother access to Spinner's Snare, which allows her to create invisible lines on her webs from Spin Web that will root Nature's Prophet, deal damage over time to Nature's Prophet and reveal Nature's Prophet if he unwittingly steps on them, disrupting his attempts to perform surprise attacks on Broodmother's allies with Silver Edge and also prevent him from using Silver Edge to esacape, while also alerting Broodmother on his attempts to ambush her and her allies.
Additional:
* Broodmother can destroy Nature's Prophet's Treants with Spawn Spiderlings and summon spiderlings in their place.
* Broodmother loves buying Orchid Malevolence, which can prevent Nature's Prophet from escaping with Sprout and Teleportation.
