Every time Zac damages at least one enemy with an ability, and for every enemy champion beyond the first hit by Elastic Slingshot, he sheds a chunk of himself to a nearby location which lands towards visible nearby enemy champions, if any, and lasts 6 seconds. Zac and enemies can move over these chunks to consume them, and if Zac does so he heals for 4% maximum health.
Upon taking fatal damage, Zac splits into 4 uncontrollable bloblets that move to his final location over 8 / 7 / 6 / 5 / 4 seconds. If any of these bloblets remain at the end of the duration, Zac recombines and returns at 10 - 50%maximum health, based on his bloblets' total remaining health.
Additionally, Zac's size scales with his current health.
Cell Division grants two passive effects: one that triggers whenever Zac lands one of his abilities; and one that triggers when Zac takes fatal damage.
Cell Division has two spawn behaviors for chunks - "contestable" and "non-contestable". Non-contestable is used by default, with contestable being used if there is a visible enemy champion within 1000 units of Zac.
Non-contestable: Chunks will fall to the ground near to Zac and can be picked up immediately.
Contestable: Chunks will fall to the ground between Zac and the nearest enemy champion, slightly in favour of Zac. Chunks cannot be interacted with for the first 0.25 seconds, except during Let's Bounce!.
The pick-up radius is the same for both Zac and enemy champions (50).
Zac's abilities cost 4% of his current health while chunks heal 4% of his maximum, a net heal of 4% of his missing health.
Zac gets larger when his current health exceeds the base health for his level.
Zac reduces Unstable Matter'scooldown by 1 second every time he picks up a chunk of Cell Division's. Picking them up while Unstable Matter is available instead reduces the cooldown of his next Unstable Matter by up to 1 second.
A grabbedBloblet will not cause Zac to take longer to revive, or to revive with less health, even though the Bloblet itself is visually separated from the others.
Allies can Teleport to Bloblets, rendering them invincible for the duration.
For the purposes of Kha'Zix'sTaste Their Fear, Bloblets are treated as isolated; however, if they move enough near each other, they will not be treated as isolated anymore. They will return to be isolated if only one Bloblet remains, or at the moment that they recombine.
Turrets will prioritize Bloblets over other minions.
