Official ability descriptions

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.

Riot's official tips for playing Zac
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.
How to play around Zac's combos
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.
