* Lifestealer is a susceptible target to Fervor due to his non-mobile nature and lack of disables. Troll Warlord's ranged Berserker's Rage can also be used to kite Lifestealer safely. The root from its melee form also pierces magic immunity, which can potentially keep Lifestealer in place even while he is in Rage.
* Both Whirling Axes (melee) and Whirling Axes (ranged) can force Lifestealer to cast Rage too quickly and allow Troll Warlord to change strategies mid-fight, especially thanks to their separate cooldowns.
* Battle Trance allows Troll Warlord to survive Lifestealer's Feast and turn the fight in his favor.
Additional:
* The passive armor provided by Berserker's Rage makes Troll Warlord resilient to Feast in early game.
* The 60% miss chance given by Whirling Axes (Melee) is useful when Rage is not active.
* Battle Trance can purge Open Wounds, negating a large amount of Lifestealer's sustain in fights.

* Jakiro's reliance on his abilities can cause struggles for heroes who rely on evasion or blinds to get upper hand: Phantom Assassin, Windranger, Riki, Troll Warlord, Keeper of the Light.

* Heroes with channeling spells are very easy targets for Jakiro's abilities: Crystal Maiden, Dawnbreaker, Enigma, Pudge, Shadow Fiend, Shadow Shaman, Warlock.

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

* Jakiro's wide area-of-effect abilities allow him to clear the waves of Terrorblade's illusions and to damage real Terroblade.
* Both, Liquid Fire and Liquid Frost from Aghanim's Shard deal magical damage, which can bypass Terrorblade's high armor.
* Jakiro often buys Hurricane Pike, which combined with +275 Attack Range talent allows Jakiro to harass Terrorblade from safe distance without getting in range of Sunder and outrange Terrorblade greatly, even during Metamorphosis.
* Aghanim's Scepter upgraded Macropyre can deal huge pure damage to Terrorblade and his illusions and can hurt real Terrorblade even if he is protected by Black King Bar thanks to it's ability to pierce spell immunity when upgraded.
* Just bear in mind, however, that Jakiro's abilites are all dealing damage-over-time, so a well-timed Sunder may spell a doom for Jakiro if Terrorblade can get close to him unless Jakiro builds Black King Bar or Linken's Sphere and other items that can give him a burst damage.

* Terrorblade cannot go one on one against Troll Warlord as Troll Warlord will overwhelm him faster than the other way around thanks to Whirling Axes (Melee) that will cause his attacks to miss, and Fervor that can give Troll Warlord huge amounts of attack speed to outmatch Terrorblade, even during Metamorphosis.
* Troll Warlord's high attack speed from Fervor combined with Skull Basher and Abyssal Blade means that Terrorblade will have almost no chance to use Sunder to save himself.
* Even if Terroblade manages to use Sunder on Troll Warlord, Troll Warlord will simply be able to nullify it's effect with Battle Trance.
* Overall, any attempt for Terrorblade to engage and kill Troll Warlord will hurt him more than the other way around.

* Even if Terroblade manages to use Sunder on Troll Warlord, Troll Warlord will simply be able to nullify it's effect with Battle Trance.

* Jakiro's abilities deal damage over time, which can disrupt Magnus's attempts to initiate with Blink Dagger and Reverse Polarity.
* Macropyre not only disables Blink Dagger for a considerable duration, but can also destroy Trees, revealing Magnus's cover and position.

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

* Jakiro's early pushing ability from Liquid Fire makes Jakiro very strong against heroes, that take a long time to get online: Morphling, Naga Siren, Spectre.

* Generally speaking, Spectre is a strong teamfighter but a weak manfighter. She has no tool to deal with troll warlord once he has his sight locked on her.
* Troll often buys Silver Edge and Monkey King Bar, which greatly countered Spectre's passive and item build (Silver Edge can disable passive while providing some damage, Monkey King Bar provides accuracy to counter Radiance and Butterfly miss chance).
* Black King Bar allows troll to bypass the damage return from Blade mail should Spectre attempts to fight back Troll. However, Black King Bar is generally not very effective against Spectre as her skills can pierce the spell immunity. Still, it offers protection against Blade mail, a common item for Spectre in the mid game.
* Troll has high lifesteal from Battle Trance and Satanic, which help him survive the damage from Desolate should the break duration is over.
* Battle Trance and Fervor mean Spectre will have a hard time fighting troll and cannot take him down, even with equal farm.

* All of Jakiro's skills are Area of Effect, which can easily affect all Meepos in a targeted area.

* Troll Warlord can root and deal a lot of damage to a single Meepo while lifestealing through the assault from the other Meepos. Meepo needs expensive items like Ethereal Blade or Heaven's Halberd to be able to fight him.

* Heroes who rely on damage over time as Spiked Carapace can block and reflect only one instance of damage: Jakiro, Viper, Venomancer, Huskar, Ember Spirit, Dark Seer, Sand King, Doom, Dawnbreaker. However, this also means they are easily stunned.

* Heroes who build Black King Bar as either core or situational item will be able to fight back against Nyx Assassin and freely attack him as Spiked Carapace cannot pierce spell immunity at all: Axe, Broodmother, Dawnbreaker, Enigma, Huskar, Jakiro, Legion Commander, Lina, Luna, Lycan, Slardar, Slark, Troll Warlord, Witch Doctor.

* Jakiro's early pushing ability from Liquid Fire makes Jakiro very strong against heroes, that take a long time to get online: Morphling, Naga Siren, Spectre.

* Heroes that rely on right-clicks will find that their attacks will miss a lot, due to Whirling Axes (Melee)'s miss chance. Such heroes include Phantom Assassin, Terrorblade, and Morphling.

* Jakiro's reliance on his abilities can cause struggles for heroes who rely on evasion or blinds to get upper hand: Phantom Assassin, Windranger, Riki, Troll Warlord, Keeper of the Light.

* Whirling Axes (Melee) makes it hard for Phantom Assassin to land a Coup De Grace.
* Troll Warlord often buys Silver Edge and Monkey King Bar, the items that greatly help against Phantom Assassin's Blur ability.
* Battle Trance completely negates Phantom Assassin's large damage output, preventing Troll Warlord from dying easily. The lifesteal also allows Troll Warlord to restore much of his health.
Additional:
* Troll Warlord can build a Silver Edge or a Monkey King Bar to completely ignore Blur.
* Whirling Axes (Melee) provides a 60% miss chance, making a Coup de Grace critical strike very hard to land.
* Battle Trance negates Coup de Grace, preventing Troll Warlord from dying to her critical hits.

* Battle Trance and Fervor can help Troll Warlord deal with Enchantress through Untouchable.
Additional:
* Untouchable's attack speed slow is easily remedied by Fervor stacks and Battle Trance.
* Troll Warlord is a natural Silver Edge carrier, disabling Enchantress' Untouchable.

* Dual Breath, Liquid Fire, Liquid Frost from Aghanim's Shard and Macropyre allows Jakiro can clear Chen's creeps, and kill his allies before he uses Hand of God.
* Macropyre can quickly clear Chen's creeps and deal intense damage to his allies, Aghanim's Scepter upgraded Macropyre can also deal pure damage to Chen and his creeps and allies and pierce spell immunity.
Additional:
* Jakiro's damage over time force Chen to use Hand of God prematurely, potentially wasting chance to save his allies during teamfight.
* Dual Breath and Macropyre can be used to disrupt Chen's jungling work.

* Jakiro's damage over time abilities can clear Naga Siren's illusions and can hurt real Naga Siren even for the duration of Song of the Siren.
* Naga Siren is not a hero that likes to go for Black King Bar, and that makes her very vulnerable to Jakiro's damage over time in every phase of the game.
Additional:
* Jakiro's damage over time abilities can clear Naga Siren's illusions and can hurt real Naga Siren even for the duration of Song of the Siren.
* Since Naga Siren is a hero who barely goes for Black King Bar, this can make her very vulnerable to Jakiro's damage over time in every phase of the game.

* Batrider has poor survivablilty, relying on his mobility from Firefly to survive. Stunning him with Ice Path of Liquid Frost can easily spell his doom.
* Batrider tends to cast Flaming Lasso on the squishest or the tankiest hero. Which Jakiro is not squishy, nor his generally the tank of the team, Due to this, Jakiro can usually save allies with Ice Path and Liquid Frost, while also potentially removing an entire hero from play for a short period of time.
* Even if Batrider does cast Flaming Lasso on Jakiro, Batrider will generally drag Jakiro into a great setup for Ice Path and Macropyre.

* Jakiro's spells inflict AoE damage, meaning he can take down Phantom Lancer's illusion army very quickly.
* Bear in mind, however, that once Phantom Lancer buys Diffusal Blade which can burn Jakiro's mana, Jakiro will be vulnerable to Phantom Lancer 's counter-attacks if he runs out of mana.
Additional:
* Jakiro's AoE abilities are great against Phantom Lancer:
* Dual Breath slows down and damages Phantom Lancer and his illusions.
* Liquid Fire will not only deal AoE damage but also lowers Phantom Lancer's attack speed.
* Ice Path and Macropyre combo can easily clear all of Phantom Lancer's illusions.
* Jakiro can predict Doppelganger and Ice Path on top.

* Dual Breath and Liquid Fire reduces Tiny's already abysmal Attack Speed.
* If Tiny Tosses a hero onto Jakiro, he can react with Ice Path, and potentially Macropyre.
* Tiny's Avalanche is easily countered with Ice Path.
* As Tiny has a very high Health, Liquid Frost is particularly effective against him.

* Even though Luna can easily kill Jakiro in few strikes, he can also do the same to her is she is not careful.
* Dual Breath and Liquid Fire allow Jakiro to harass Luna more efficiently than she can harass Jakiro with her Lucent Beam.
* Jakiro can save his allies from Luna during her attempts to use Eclipse by casting Ice Path on Luna.
* Aghanim's Scepter upgraded Macropyre can deal pure damage-over-time and pierce spell immunity, which can make it very hard for Luna to be in teamfights without suffering too many damage.
* For the same reasons, Jakiro makes a very powerful ally for Luna when they are in the same team.
Additional:
* Even though Luna can easily kill Jakiro in few strikes, he can also do the same to her is she is not careful.
* Dual Breath and Liquid Fire allow Jakiro to harass Luna more efficiently than she can harass Jakiro with her Lucent Beam.

* For the same reasons, Jakiro makes a very powerful ally for Luna when they are in the same team.

* 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.

* Whirling Axes (Melee)'s blind makes Sven nearly useless in the early game and allows Troll Warlord to take him on comfortably.
* Battle Trance will mean Sven will never take Troll out in a 1vs1 with equal farm.
Additional:
* Berserker's Rage together with Troll Warlord's high attack speed gives Troll a high chance of rooting enemies, which allows Troll Warlord to man-fight Sven.
* Whirling Axes (Melee) provides a 60% miss chance, and the passive armor provided by Berserker's Rage makes Troll resilient to physical damage in early game. Sven's God's Strength is much less effective as a result.
* Beware that Sven can farm much faster than Troll Warlord by stacking ancients and clearing them with Great Cleave.

* Despite Jakiro's fragileness, he can easily harass Shadow Fiend with Dual Breath and Liquid Fire than Shadow Fiend can harass Jakiro with Shadowraze.
* Jakiro can easily cancel Requiem of Souls with Ice Path as Shadow Fiend is a very easy target while channeling it.
* Aghanim's Scepter upgraded Macropyre can deal pure damage-over-time and pierce spell immunity, which can discourage Shadow Fiend from even trying to initiate with Requiem of Souls.

* Aghanim's Scepter upgraded Macropyre can deal pure damage-over-time and pierce spell immunity, which can discourage Shadow Fiend from even trying to initiate with Requiem of Souls.

* Riki can easily be caught in an Ice Path and Macropyre combo as he finishes Tricks of the Trade, Jakiro just has to be careful about Riki's Smoke Screen when dealing with Riki.

* Death Ward can be easily canceled by Jakiro, or even turned against him with Macropyre, due to it's attack range being smaller then Jakiro's cast range. And Crystal Maiden, his Scepter does not allow him to move while using it. Voodoo Switcheroo is even easier to land Jakiro's Macropyro/Ice Path combo. And unlike Crystal Maiden, Witch Doctor's Aghanim's Scepter upgraded Death Ward does not allow him to move while using it.
* While Maledict can be quite effective on Jakiro, along with repetitive stuns from Paralyzing Cask, it is very difficult to get a strong Maledict on him. Although Witch Doctor's Paralizying Cask, Maledict and Death Ward combo will still quickly eliminate Jakiro.
* On the other hand. Voodoo Restoration will partly protect his allies from Jakiro spells, as it heals based on their Max Health once he gets his Talent (Level 25). Before then though, it won't make a dent in the damage Jakiro deals.

* Mana Drain can be easily canceled with Ice Path. However, Lion can counter this by buying his Aghanim's Shard though, that is no longer possible, but Jakiro can counter this too with Aghanim's Scepter upgraded Macropyre will deal pure damage through the debuff immunity forcing Lion to cancel it or die.
* Lion has very strong single target capabilities, but usually struggles against multiple heroes, while Jakiro has good multi-target capabilities, His abilities also have a much shorter cast range then Jakiro's, allowing Jakiro to cast his abilities before he can get off his Hex or Earth Spike.
* Jakiro can also save an ally who Lion is attempting to Finger of Death by casting Ice Path on Lion.

* Whirling Axes (Melee) provides a 60% miss chance, which can make the attack speed bonus from Hunter in the Night largely ineffective.
* Berserker's Rage together with Battle Trance and Fervor stacks gives him a high chance of rooting Night Stalker, which allows Troll Warlord to man-fight Night Stalker in any stage of the game, regardless of whether or not it's night.
* Night Stalker is not a common Monkey King Bar carrier to counteract this problem.

* Jakiro has 3 damage over time spells, 2 of which are from debuffs on Puck (Dual Breath and Liquid Fire) and 1 affecting an entire area (Macropyre), making it easy for him to disable the Blink Dagger.
* Ice Path is also strong against Puck, as he can cast it towards Puck during Phase Shift, who then gets instantly stunned once Phase Shift ends.
Additional:

* Ice Path is also strong against Puck, as he can cast it towards Puck during Phase Shift, who then gets instantly stunned once Phase Shift ends.

* Most of the of Jakiro's damage-over-time abilities put Blink Dagger on cooldown, potentially forcing Enigma to prematurely activate Black King Bar.
* Jakiro's Dual Breath, Liquid Fire, Macropyre and Liquid Frost from Aghanim's Shard can take out Enigma's Eidolons, reduce Enigma's attack speed and put Enigma's Blink Dagger on cooldown.
* Jakiro can easily cancel Black Hole with Ice Path as Enigma is a very easy target while channeling it.
* Aghanim's Scepter upgraded Macropyre can deal pure damage-over-time and pierce spell immunity, which can discourage Enigma from even trying to initiate with Black Hole.

* Aghanim's Scepter upgraded Macropyre can deal pure damage-over-time and pierce spell immunity, which can discourage Enigma from even trying to initiate with Black Hole.

* Even though carry Silencer can easily take down a support Jakiro with his Glaives of Wisdom, Jakiro can also do the same to Silencer if he is not careful and if Jakiro is not played as support. As Silencer is rather squishy and lacks escape mechanisms without items, and Jakiro's damage over time abilities can take advantage of this.
* Ice Path can be used to prevent Silencer from escaping. And if Jakiro uses Ice Path along with Macropyre and Dual Breath in anticipation right before Silencer uses his abilities to disable Jakiro, Jakiro will be able to kill Silencer before he even gets a chance to do anything to Jakiro.
* Dual Breath, Liquid Fire and Liquid Frost from Aghanim's Shard can greatly reduce Silencer's attack speed.
* Aghanim's Scepter upgraded Macropyre can deal huge pure damage to Silencer even if Silencer is spell immune.
* Bear in mind, however, that Jakiro should approach Silencer carefully as Silencer's Arcane Curse, Last Word and Global Silence prevents Jakiro from casting any spell. Jakiro, however, can counter this by going for Guardian Greaves, a common item on support Jakiro, and with Black King Bar and Manta Style, a situational items on Jakiro.

* Both Ice Path and Macropyre are the good setup against Earthshaker after he jumps in with Blink Dagger, and stay out of Echo Slam initiation radius.
* Jakiro's damage over time abilities can potentially disable Earthshaker's Blink Dagger.

* Broodmother and her Spiderlings need to be very careful during the laning stage against Jakiro, as Jakiro can take down Broodmother's Spiderlings, preventing her from pushing as well as gaining a good amount of gold.

* Due to Fervor and Battle Trance, Troll Warlord has a significant attack speed, enabling him to crush Tombstone quickly.
* Undying usually stays at the front line with no disables, making him an easy target for Troll Warlord.

* All of Jakiro's active skills can be targeted on an area, which is effective at forcing Templar Assassin to move should she Meld away.
* Many of Jakiro's spells utilize damage-over-time mechanics, which makes it easy to strip away layers of Refraction.

* Jakiro's area-of-effect ability arsenal allows him to affect multiple heroes at once, giving Io difficulties in saving them as he can only heal one hero at a time with Tether.
* Ice Path can be used to cancel both, Tether and Relocate.
* Jakiro commonly buys Rod of Atos that can be used to cancel Relocate, prevent Io in escaping with Tether and make Io easy target for Ice Path and Macropyre.

* Mobility heroes will often be rooted by Troll Warlord and unable to escape, like Storm Spirit.

* Ice Path allows Jakiro to easily cancel Freezing Field.
* Freezing Field makes Crystal Maiden an easy target for all of his abilities without a Black King Bar.
* With the Aghanim's Scepter upgraded Macropyre, Black King Bar becomes nearly useless for Crystal Maiden, as its high pure damage over time, long duration and ability to pierce spell immunity will either force Crystal Maiden to forcefully cancel Freezing Field or even discourage her from using it at all.
Additional:
* Ice Path allows Jakiro to easily cancel Freezing Field.
* Freezing Field makes Crystal Maiden an easy target for all of Jakiro's abilities without a Black King Bar.
* Aghanim's Scepter upgraded Macropyre can deal pure damage-over-time and pierce spell immunity, making Black King Bar nearly useless for Crystal Maiden, as its high damage over time and long duration can discourage Crystal Maiden to use Freezing Field. Remember, however, that Crystal Maiden can partially solve this issue by buying Aghanim's Shard, which will allow her to simply walk out of Macropyre.

* Heroes with a low attack speed or are fragile will find themselves unable to deal with Troll Warlord's high physical damage and attack speed, like Crystal Maiden or Sven.

* Jakiro's reliance on his abilities can cause struggles for heroes who rely on evasion or blinds to get upper hand: Phantom Assassin, Windranger, Riki, Troll Warlord, Keeper of the Light.

* Troll Warlord's melee bash and high attack speed can often help him and his allies win Duels against Legion Commander.

* Any hero with high attack speed will be a threat to Phoenix when it initiates, as they can easily tear down a Supernova, perhaps even while debuffed by Fire Spirits: Juggernaut, Clinkz, Troll Warlord, Beastmaster, Lina.

Additional:
* Due to Fervor and Battle Trance, Troll Warlord is one of the best heroes to deal with Supernova.

* Heroes with channeling spells are very easy targets for Jakiro's abilities: Crystal Maiden, Dawnbreaker, Enigma, Pudge, Shadow Fiend, Shadow Shaman, Warlock.

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

Additional:
* Whirling Axes (Melee) provides a 60% miss chance, resulting in Huskar's attacks missing a lot of the time if it isn't dispelled.
* Troll Warlord's Fervor ramps up in a very similar way as Huskar's Berserker's Blood: as soon as Huskar has high enough health regeneration, Troll Warlord has a high enough attack speed to negate it.

* Jakiro's area-of-effect abilities make him strong against heroes who rely on illusions and summons: Terrorblade, Naga Siren Chaos Knight, Phantom Lancer, Broodmother, Nature's Prophet, Lycan, Wraith King, Visage.

* Chaos Knight usually doesn't buy a Black King Bar, making him vulnerable to an Ice Path into Macropyre combination.

* With Dual Breath, Liquid Fire and Macropyre Jakiro can quickly remove all Living Armor from a target.
* Ice Path allows Jakiro to prevent Treant Protector from using Overgrowth while staying at a safe distance.

* 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.

* Berserker's Rage will repeatedly trap Bloodseeker in a one-on-one fight.
* Whirling Axes (Melee) blinds Bloodseeker, causing him to miss 60% of the time, and therefore reduces his ability to gain the upper hand in teamfights.

* Jakiro's area-of-effect abilities that deal magical damsge make it hard for Omniknight to save multiple enemy heroes at once with Purification and Repel, and Guardian Angel and to harass Omniknight on lane.
* Aghanim's Scepter upgraded Macropyre allows Jakiro to deal pure damage and slow enemy heroes which can pierce debuff immunity, rendering both Repel and Guardian Angel useless.

* Jakiro relies entirely on dealing damage through his area-of-effect abilities, making Enfeeble less effective against him, although it will still reduce his cast range.
* An ill-timed Nightmare can give Jakiro a good setup for all of his ablities.
* Jakiro can easily cancel Fiend's Grip with Ice Path, as Bane is very easy target while channeling it.

* Tinker's Laser has very little effect on Jakiro.
* Tinker has to sit still for a short period of time due to Rearm, not only making it easy to catch him with Ice Path, but also by stunning him while he is Rearming, Jakiro generally spell Tinker's doom.
* With s high area-of-effect and strong damage-over-time capabilties, Jakiro can quickly burn through his Defense Matrix, and at the same time lock down his Blink Dagger. Both of which he relies heavily to survive on.

* Troll Warlord's ability to attack as a ranged hero allows him to destroy Juggernaut's Healing Ward from afar.
* Battle Trance, when activated during Omnislash, allows Troll Warlord to survive the full duration of Omnislash and retaliate once it is over.

* Dual Breath and Liquid Fire can be used to harass Muerta on lane.
* Ice Path can be used to stun Muerta when she uses Pierce the Veil, giving his allies time to escape or counter-initiate against Muerta.
* Aghanim's Scepter upgraded Macropyre can deal pure damage and pierce debuff immunity, rendering both, Pierce the Veil and Black King Bar useless.
* However, Jakiro is vulnerable to Muerta's The Calling as it can easily silence him due to his low mobility. In addition, Liquid Fire and Liquid Frost from Aghanim's Shard will not be able to be used on Muerta while Pierce the Veil is active unless she is near the enemy hero Jakiro targets with Liquid Fire and Liquid Frost or until Jakiro buys Revenant's Brooch.

* Jakiro's area of effect abilities can hit Dark Willow even while she is hidden during the Shadow Realm.
* Waiting about 2 seconds after Dark Willow casts Shadow Realm to cast Ice Path will stun her while her Shadow Realm is at it's maximum damage.
* Jakiro can stun Dark Willow when there is about 1 second left on Cursed Crown, Jakiro's Ice Path stun lasts slightly longer then Cursed Crown.

* While Jakiro's damage is going to be little more then average against him due to his Bristleback. His large quantity of stuns can prevent Bristleback from getting his much needed Warpath stacks, while also giving his allies a chance to counter his high defense.
* Dual Breath and Liquid Frost both reduce Movement Speed, removing one of Bristlebacks greatest strengths.
* Liquid Fire reduces Bristlebacks Attack Speed, making it harder for him to burst down a hero with Warpath.
* However Bristleback can generally catch and kill a lone Jakiro. And Jakiro is only effective in a group.

* Both Jakiro's Ice Path and Liquid Frost can be used to cancel Life Drain from either Jakiro or an ally.
* Decrepify only makes Pugna even more vulnerable to Jakiro's magical damage, And it has no adverse effects on Jakiro himself.
* Aghanim's Scepter upgraded Macropyre can deal pure damage-over-time and pierce debuff immunity, which can discourage Pugna from even trying to use Life Drain.
* Bear in mind, however, that Nether Ward can do some considerable damage to Jakiro due to high mana costs on his abilities.

* Ice Path is a great stun for Berserker's Call and with a Eul's Scepter of Divinity can really catch Axe off guard.
* Dual Breath and Liquid Fire can be a devastating combination for Axe (especially if he takes Battle Hunger at level 1) before he has any natural regeneration sustain from items.
Additional:
* Ice Path neutralizes initiation attempts with Berserker's Call, and its long area of effect discourages follow-ups from Axe's teammates until Axe buys Black King Bar.
* Ice Path serves as a large obstacle to stop Axe from chasing down fleeing stragglers to kill with Culling Blade until Axe buys Black King Bar.
* Jakiro's many damage-per-second skills prevent Axe from initiating with his Blink Dagger. Forcing Axe to buy Black King Bar prematurely to protect himself against Jakiro's abilities and counter-initiaions.

* Troll Warlord's passive root, high attack speed, and blind from Whirling Axes makes him an exceedingly difficult opponent for Anti-Mage to take down in a one-on-one fight.
* Troll Warlord's low mana causes him to take little damage from Mana Void.
Additional:
* Whirling Axes (Melee) provides a 60% miss chance, preventing Anti-Mage from burning Troll Warlord's small mana pool.
* Troll Warlord's passive root allows him to very effectively fight an Anti-Mage by preventing Anti-Mage from Blinking away. This is even more effective when combined with a Skull Basher or Abyssal Blade.
* Counterspell will do nothing to prevent Troll Warlord's high physical damage.
* Due to Troll Warlord's abysmal base intelligence and intelligence gain, he is one of the worst targets to use Mana Void on.
