Cell Division
Cell Division

Each time Zac uses an ability on enemies, he sheds a chunk of himself to a nearby location, lasting 6 seconds. Zac can move over these chunks to reabsorb them, regaining 4% of his maximum health. Enemies may move over these chunks to destroy them.

Upon taking fatal damage, Zac splits into 4 Cell Division Bloblets that attempt to recombine. Each Cell Division Bloblets has 12% of Zac's maximum health, and 50% of his armor and magic resistance. If any of these Cell Division Bloblets remain after 8 seconds, Zac will revive with 10-50% health depending on the health of the surviving chunks.

Ability Details
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.

Additional Information:

  • 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!.png 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.
  • Chrono Shift.png Chrono Shift and Guardian Angel item.png Guardian Angel will take precedence over Cell Division.
  • Cell Division.png Bloblet
    • Bloblets are not controllable and are functionally minions.
    • Bloblets can be Smite.png Smited, Consume.png Consumed, or Force of Will.png grabbed.
      • A Force of Will.png grabbed Bloblet 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.png Teleport to Bloblets.
      • As this renders them invincible, Teleport.png Teleport can be used to guarantee a successful revive if timed correctly.
    • For the purposes of KhaZixSquare.png Kha'Zix's Taste Their Fear.png Taste 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.
    • Bloblets ignore airborne effects and take 33% reduced AoE damage.
