Cell Division

Cell Division

Each time Zac hits an enemy with an ability, he sheds a chunk of himself that can be reabsorbed to restore Health. Upon taking fatal damage, Zac splits into 4 bloblets that attempt to recombine. If any bloblets remain, he will revive with an amount of Health depending on the Health of the surviving bloblets. Each bloblet has a percentage of Zac's maximum Health, Armor and Magic Resistance. This ability has a 5 minute cooldown.

Tips for Allies

  • Picking up goo chunks is very important to staying alive.
  • When Cell Division is ready, try to die in a position that makes it difficult for the enemy team to kill your bloblets.
  • Charging Elastic Slingshot from the fog of war will give opponents less time to react.

Tips for Enemies

  • Zac heals from the goo that separates from him. You can crush the goo pieces by stepping on them.
  • Kill all of Zac's bloblets when he splits apart to stop him from reforming.
  • Silences, stuns, roots and knockups will all interrupt Zac when he is charging Elastic Slingshot.


Zac is the product of a Zaun experiment to manufacture a hexchem-engineered supersoldier - the Zaun Amorphous Combatant. Combining brute strength with limitless flexibility, he is a versatile juggernaut: a creative fighter who bounces over obstacles and pounds his foes into submission. Though he was created inside a weapons laboratory, Zac was rescued and adopted by two loving parents who raised him to be a kind and friendly child. As the years passed, he grew up to be a fierce hero, sworn to protect the ordinary, everyday people of Zaun.

Long ago, two Zaun scientists developed an organic substance that could withstand extreme conditions, spontaneously alter its biological structure, and generate tremendous amounts of kinetic force. As the scientists, husband and wife, watched the prototype grow from a spoon-sized droplet to a small blob, they noticed that their creation would respond to their presence. It sprung forward when they called and bounced when they sang. The couple began to see more than an experiment; they saw a small child, filled with affection and joy.

After testing the prototype one evening, the scientists placed the blob back in its cage. It slouched and shuddered in the corner, inconsolably sad. At that moment, the couple realized that their beloved creation wished for a free life outside the lab. They were struck by their conscience and could not allow the prototype to be used as a weapon. The husband and wife fled with the young blob, replacing its weapon designation - Zaun Amorphous Combatant - with a proper name: Zac. In a quiet neighborhood far from the cities of Zaun, the scientists raised Zac as their own child.

Zac was always different from the other children. None had his powers of strength and flexibility, so the couple taught him to tell right from wrong and to use his gifts responsibly. Thanks to the care and affection of his loving parents, Zac lived a peaceful, happy childhood.

That childhood ended when the Zaun laboratory finally found Zac. Unable to replicate the formula used to create the amorphous prototype, the laboratory's staff never stopped searching for the scientists and their experiment. When they tracked down the family, they threatened to tear it apart. The staff abducted Zac's parents and demanded that the couple assist in his capture and return. Seized by the fear of losing his freedom and his parents, Zac unleashed every ounce of his raw energy and mass for the very first time. He subdued his parents' captors, sent the laboratory's workers fleeing, and brought his loved ones home. From then on, Zac vowed to defend all ordinary lives threatened by extraordinary treachery and wickedness. Originally built to destroy, he now protects the innocent and the helpless.

''Even if you don't have a spine, you still have to stand up for yourself.''
-- Zac
