Zac Ability (LoL): Cell Division
Cell Division Zac
Passive
Upon taking fatal damage, Zac splits into 4 chunks that attempt to recombine. If any of these chunks remain after 8 / 7 / 6 / 5 / 4 seconds, he will revive with 10-50% health depending on the health of the surviving chunks. Each chunk has 12% of Zac's maximum health, and 50% of his armor and magic resistance. This ability has a static cooldown and is unaffected by cooldown reduction.
The revival speed is increased every 4 levels.
Also for it's other effect: 12-60% hp depending on the health of surviving chunks.
