Creates a copy of himself to split push

A splintered fragment of the same primordial power as the Ancients themselves, Zet the Arc Warden has pledged to see the clash between Radiant and Dire finally end. Assault lone enemies with fluxing energy, or distort space to generate a protective field around allies. Summon a Spark Wraith to patrol an area for enemies to infuse with harmful magic, then create a double of Zet, items and all, to overwhelm your foes.

Make use of Spark Wraiths to secure creep last hits, especially ranged creep.

If an opponent splits away from creeps or his ally, you can Flux him and follow up with right-clicks and Spark Wraiths.

Use Spark Wraiths to scout the opponents and protect yourself while farming.

Make sure not to feed Tempest Double to opponents as it gives away a lot of gold and experience.

Use Tempest Double as frequently as possible to split push the sidelanes and damage buildings.

Avoid being part of the teamfights from the very start until you get first major item that will tank you up.

Whenever opponents teleport back on a hero or two to address your split push, look to fight the remaining opponents, smoke up or take Roshan.

    Briefly refocusing its fractured elements into a single form, the Arc Warden is able to create a perfect electrical duplication of itself. The duplicate can use all of Arc Warden's current items and special Tempest Double versions of his spells, except most consumables and items that drop on death. The duplicate has separate item and ability cooldowns.If killed by the enemy, the Tempest Double gives bounty gold to enemies, and the ability's cooldown is restarted.The Tempest Double loses its sense of self if he is too far away from Arc Warden and takes more damage.

    Before the beginning of all, there existed a presence: a primordial mind, infinite, awesome, and set to inscrutable purpose. As the universe thundered into being, this mind was fragmented and scattered. Two among its greater fragments--who would come to be named Radiant and Dire--found themselves locked in vicious opposition, and began twisting all of creation to serve their conflict. As war and cataclysm threatened the nascent cosmos, the will of a third fragment made itself known. Naming itself Zet, this intellect sought to resolve the disharmony and return all to perfect unity. Appalled by its kin's conflicting nature, Zet gathered the sum of its power. In a sudden flash, it overwhelmed its siblings, and fused the warring aspects into a stellar sphere before hurling them into the darkness to orbit a nondescript world. Harmony was restored, though only the barest fraction of Zet's strength remained. Setting its gaze on the prison, Zet chose to use its weakened power to serve as watchful warden until time's end. For uncounted aeons, this vigil stood. Life flourished upon the world below, oblivious to the dangers imprisoned within the softly glowing moon, or of Zet's struggles to contain them. As the captives' eternal clash reverberated within, the surface of the prison shuddered, over time beginning to crack. Ultimately, Zet's depleted power proved insufficient to contain the breach, and at last the moon was shattered. The prison's ancient inhabitants had escaped to sow their conflict anew. Flung to the farthest reaches by the prison's explosion, Zet was transformed by the dissonant energies of its former captives. No longer of single form and thought, its presence had become split among many--some lesser, some greater--each connected by a fleeting arc of consciousness. Struggling to suppress its own disunity, Zet sped toward the burgeoning conflict of its siblings, bending its fractured wills toward a singular conclusion: the aspects of the primordial mind must be made to reunite, or all must be destroyed lest the conflict spread further...
