Jakiro

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 miniscule, making him a great hero for ganks, pushes and clashes across the battlefield.

Tips

 * When getting to level 6, you may opt to skip your ultimate when you don't have Arcane Boots, as the crowd control it does in comparison to spamming your other abilities is far less efficient for its mana cost.
 * Leveling Ice Path over Liquid Fire and Dual Breath is not advisable as each level of Ice Path only adds 0.4 seconds of duration and 1 second of cool down and no additional damage. Leveling Ice Path past level 1 does not provide much additional impact in the early game.
 * If you are going to max out Liquid Fire at level 7, you may want to opt for different boots, since you wouldn't be consuming enough mana for Arcane Boots to be truly useful. Instead, you can go for Phase Boots for mobility and damage, Power Treads for durability and attack speed, Tranquil Boots for HP regen and mobility, or even keep it as brown boots to later upgrade it to Boots of Travel, giving you the ability to push out lanes when you find it suitable, as well as surprising enemies with your presence in a teamfight.
 * On level 1 Dual Breath does similar damage to Ice Path. So your choice is between a 5 second 28% ms/28 as slow from Dual Breath or a 1 second stun from Ice Path.
 * The huge range and lasting area effect of Ice Path make it roughly analogous to Earthshaker's Fissure. It is an amazing spell for opening up opportunities to fight or to shut down aggression. It doesn't do much damage however.
 * If another hero in your team is already getting Mekansm, you can instead buy a Veil of Discord to not only boost your already high magical damage, but your teammates' as well.
 * Liquid Fire is a spell with a smaller area of effect but has the largest damage growth (the dps for all four levels roughly doubles for each level and the dps is as follows: 3.75/6.67/12.5/30), but its effect is free additional damage and provides an attack speed slow, and should be prioritized during the early game as it can be active consistently when fully leveled.
 * Hits with Liquid Fire are very useful for tower pushing as it reduces their attack speed and deals damage even if Jakiro and his lane mates are not staying in tower range to attack it. Hit-and-runs with Liquid Fire can reduce tower health significantly.
 * It is also suitable for pushing lane creeps in the same way, although players should not expect to push down waves in the same way as other, more powerful lane control spells. Instead, they should use it in conjunction with Dual Breath and use the combined Damage over time to push the lane.
 * When you can afford it, opting for a Shiva's Guard can be used to stack with your Dual Breath and Liquid Fire's MS slows to maximize the time your enemies spend inside Macropyre's area.
 * Shiva's Guard also stacks with Dual Breath and Liquid Fire's attack speed slows providing even more impact.
 * Combine Macropyre with spells that keep the enemy in place as long as possible, such as Chronosphere, Black Hole or Upheaval. It does not guarantee damage without these effect and is a fairly low damage spell, so chaining it with other spells is necessary for any real effect.
 * This also works to counter enemy spells and melee heroes that require they stay in an area; throw Macropyre from outside Chronosphere, for example, to dissuade Void from attacking your teammates.

Trivia

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