Jakiro the Twin Head Dragon is a ranged intelligence hero who utilizes the powers of ice and fire with powerful linear area spells. He can freeze enemies in place with Ice Path, or slow them down with Dual Breath. He is capable of dealing heavy damage throughout the game by locking enemies inside his Macropyre, and provides great pushing power with Liquid Fire.

With high base attribute gain and relatively low mana costs, he requires few items to be effective. Jakiro is a support who can continually turn battles in his favor with good positioning. His high strength gain makes him a bit tougher than most spellcasters and his low cooldowns ensure that his downtime is very minuscule, making him a great hero for ganks, pushes and clashes across the battlefield.


Jakiro Jakiro, the Twin Head Dragon
Play "Two sides of the same coin."
Lore: Even among magical beasts, a twin-headed dragon is a freak. Equal parts ice and fire, cunning and rage, the creature known as Jakiro glides over charred and ice-bound battlefields, laying waste to any who would bear arms against it. Pyrexae dragon clutches always contain two fledglings. Famous for their viciousness even from the first moments of life, newly hatched dragons of this species will try to kill their sibling while still in the nest. Only the strongest survive. In this way is the strength of the Pyrexae line ensured. By some accident of nature, the freak Jakiro hatches from a single egg, combining in a single individual the full range of abilities found within the diverse Pyrexae species. Trapped within the armature of its monstrous body, the powers of ice and fire combine, and now no enemy is safe.

Debuff Dual Breath Burn: Dispellable with any dispel.
Pyrexae dragons have tremendously dangerous breath for each branch of the species; combining them is unimaginable.


  • Targeting a unit causes the breaths to be released towards the unit's position.
  • Both the icy and fiery wave travel at a speed of 1050, taking 0.71 seconds to travel the full distance.
  • The fiery breath is released 0.3 seconds after the icy breath is released.
    • This means it is possible for enemies to be hit by only one of the breaths, by getting in or out of range of the second breath.
    • Jakiro cannot move until both waves are released, but can use items and spells and turn a little bit between the first and the second breath.
  • Can hit units up to 1025 range away (travel distance + end radius).
  • The complete area of both breaths is shaped like a cone.
  • Deals 10/20/30/40 (Talent 30/40/50/60) damage in 0.5 second intervals, starting 0.5 second after the damaging debuff is placed, resulting in 10 instances.
  • Can deal up to 100/200/300/400 (Talent 300/400/500/600) damage to a single unit (before reductions).

Ice Path
Does not pierce spell immunity. Play
Ice Path icon.png
Target Point
Creates a path of ice that stuns and damages enemies that touch it.
Cast Animation: 0.65+0.8
Cast Range: 1200
Path Distance: 1200
Path Radius: 150
Effect Delay: 0.5
Damage: 50
Path Duration: 1/1.5/2/2.5 (Talent 2.25/2.75/3.25/3.75)
Cooldown symbol.png 12/11/10/9
Mana symbol.png 90
Debuff Ice Path Stun: Dispellable with strong dispels.
Jakiro's cunning right head calls upon its frozen heritage, glazing the earth with blistering cold.


  • Despite the visual effects, the path's effects do not have to travel, and are instantly applied after the 0.5 second delay.
  • The Ice Path starts 12 range in front of Jakiro and has a length of 1200.
    • It can hit units up to 1362 range away (starting distance + path length + path radius).
    • It can also hit units 138 range behind Jakiro, due to its radius and starting position.
  • Enemy units which come within 150 radius of the path while it is up get stunned and damaged by it.
  • The stun lasts as long as the remaining duration of the path itself.
  • The path grants 150 range flying vision along the path for its duration.

Liquid Fire
Cannot be used by illusions. Can be disjointed. Not blocked by Linken's Sphere. Partially pierces spell immunity. Play
Liquid Fire icon.png
Jakiro burns his enemies in an area of effect with fire added to his attack, while slowing their attacks.
Cast Range: 600 (Talent 850)
Radius: 300
Attack Speed Slow: 30/40/50/60 (Talent 90/100/110/120)
Damage per Second: 12/16/20/24
Duration: 5
Cooldown symbol.png 20/15/10/4
Partially pierces spell immunity. Can target spell immune enemies. Does not place debuff on spell immune enemies. Slows and attempts to deal damage if debuff was placed before spell immunity and when not dispelled.
Cannot be used by illusions. Illusions always have the fiery particles when Liquid Fire is leveled at least once before the illusions got created.
Debuff Liquid Fire Burn: Dispellable with any dispel.
The left maw of Jakiro opens, laying waste to any in its path.


  • Disjointing it, or becoming invulnerable upon impact completely nullifies the effects, including the area slow and damage.
  • Casting Liquid Fire manually uses the 600 cast range. Attacking normally with Liquid Fire on autocast uses Jakiro's default 400 attack range.
  • Successive casts of Liquid Fire do not stack, but refresh the debuff instead.
  • Deals 6/8/10/12 damage in 0.5 second intervals (before reductions), starting 0.5 second after the debuff is applied, resulting in 10 damage instances.
  • When off cooldown, the fire head's mouth drools fire (visible to everyone) and Jakiro starts using his fire head for attack animations until Liquid Fire is used.

Recommended items[edit]

Starting items:

  • Tango icon.png Tango and Healing Salve icon.png Healing Salve offer cheap health regeneration during the laning phase, allowing Jakiro to stay longer in lane and get the experience he needs.
  • Clarity icon.png Clarity allows Jakiro to replenish his mana over time, allowing him to harass enemies using his spells more, with less worry of running low on mana.
  • Iron Branch icon.png Iron Branches increase Jakiro's overall survivability by providing additional attribute bonuses for a very cheap price.
  • Animal Courier (Radiant) icon.png Animal Courier is a good item for a support to purchase. Because of Jakiro's relatively small need for gold in the early game, he can help the team by purchasing team-related items, such as the Animal Courier or Observer Ward icon.png Observer Wards.

Early-game items:

  • Boots of Speed icon.png Boots of Speed provide a significant bonus to Jakiro's movement speed, which is essential to help catch up to fleeing heroes or escape from danger himself. They can later be upgraded into Arcane Boots icon.png Arcane Boots to help with Jakiro's mana.
  • Magic Stick icon.png Magic Stick is a useful item to have when the enemy team has many spell casters in the early game. Because of its active ability Energy Charge, enemies who cast many spells will quickly fill the wand with charges, offering a later burst of health and mana.
  • Ring of Basilius (Active) icon.png Ring of Basilius gives mana regeneration and armor to Jakiro, bolstering his high mana usage and low base armor.
  • Soul Ring icon.png Soul Ring allows Jakiro to cast Dual Breath freely at the cost of health.

Core items:

  • Magic Wand icon.png Magic Wand is a cost effective upgrade from Magic Stick icon.png Magic Stick by both increasing the maximum amount of charges from Energy Charge, as well as providing additional attribute bonuses.
  • Veil of Discord icon.png Veil of Discord's active ability Magic Weakness increases the damage enemies take from spells cast by Jakiro and his team. It also gives good attribute bonuses, costs less than Aghanim's Scepter icon.png Aghanim's Scepter, and benefits all of his abilities.
  • Arcane Boots icon.png Arcane Boots are essential for Jakiro, as the additional mana pool allows him to cast his spells more frequently. The active ability Replenish Mana is also helpful to sustain Jakiro's spell usage, as well as help nearby teammates. Guardian Greaves icon.png Guardian Greaves is a natural path to upgrade to since Jakiro is commonly played as a support hero.
  • Observer Ward icon.png Observer Wards are useful for the team, providing sight to key areas around the map. As a support hero requiring less gold to be successful, Jakiro is a prime choice to purchase them.
  • Town Portal Scroll icon.png Town Portal Scroll is extremely useful for transportation across the map. After death, it can be used to quickly return to lane and not miss out on creep experience. After the laning phase, carrying one can prove helpful as both an escape mechanism and a quick way to help allied heroes across the map.

Situational items:

  • Mekansm icon.png Mekansm is highly recommended, as Jakiro is commonly played as a support hero, and it goes hand in hand with his natural build of Arcane Boots icon.png Arcane Boots into Guardian Greaves icon.png Guardian Greaves.
  • Pipe of Insight icon.png Pipe of Insight is another great item to buy as a support. If the enemy has a large amount of spell casters, it is advised that Jakiro or another allied support buy one to increase the team's overall survivability. It also provides Jakiro with a large amount of passive health regeneration, meaning he can return to base less frequently and earn more experience on the battlefield. It is advised to only carry one per team, as the damage block effects do not stack.
  • Eul's Scepter of Divinity icon.png Eul's Scepter of Divinity provides intelligence and mana regeneration at a cost effective price, and it gives Jakiro an active ability that allows him to land his spells easier. A well-timed Ice Path to follow up will guarantee the target is stunned as they fall from the cyclone. The active can also be used on himself to dispel any debuffs or silences that happen to be placed on him.
  • Rod of Atos icon.png Rod of Atos' long-ranged root can set up Ice Path as well as Jakiro's other abilities. The bonus mana and health also help Jakiro's survivability.
  • Blink Dagger icon.png Blink Dagger allows Jakiro to initiate teamfights much easier, along with the added ability to travel the map quicker and offers quick escape from incoming enemies. However it is not a guaranteed escape item, as taking damage will disable the ability to blink for 3 seconds.
  • Force Staff icon.png Force Staff acts more as an escape item compared to Blink Dagger icon.png Blink Dagger, as it can be used while taking damage. It can also be used on allies if they need to chase after a kill or escape from danger themselves.
  • Aether Lens icon.png Aether Lens' cast range increase helps Jakiro maintain a safe distance during fights. Because almost all of his abilities affect the whole area between him and the maximum cast range, this also greatly increases the area in which enemies may be hit.
  • Aghanim's Scepter icon.png Aghanim's Scepter greatly increases the effectiveness of Jakiro's Macropyre by prolonging the duration and increasing the damage of his ultimate, as well as much needed stats to remedy his health and mana pools.
  • Guardian Greaves icon.png Guardian Greaves allows a slot to be freed, provides a steady supply of health and mana regeneration to the team, and increases Jakiro's survivability.
  • Shiva's Guard icon.png Shiva's Guard provides a massive increase to Jakiro's mana pool and resistance to physical attacks. The active ability Arctic Blast provides additional damage in a teamfight and slows enemies, making Jakiro's abilities easier to hit. Freezing Aura helps reduce damage from enemy carries by slowing their attack speed.
  • Scythe of Vyse icon.png Scythe of Vyse provides a great disable with its active ability, Hex. It also provides a great increase in Jakiro's mana and mana regeneration, as well as all around attributes to help with his survivability.
  • Octarine Core icon.png Octarine Core greatly increases Jakiro's survivability by not only giving him all round health and mana boosts, but also by allowing his spells to lifesteal a portion of their damage. In addition, the cooldown reduction dramatically increases his damage and crowd control in teamfights.






  • Jakiro's fun/alternate name was Double Dragon, referring to the video game franchise developed by Technos Japan.
