Zac the Secret Weapon
Zac is the product of a toxic spill that ran through a chemtech seam and pooled in an isolated cavern deep in Zaun's Sump. Despite such humble origins, Zac has grown from primordial ooze into a thinking being who dwells in the city's pipes, occasionally emerging to help those who cannot help themselves or to rebuild the broken infrastructure of Zaun.
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.
Stretching Strikes
Zac stretches an arm, grabbing an enemy. Attacking a different enemy will cause him to throw both targets towards each other.

Zac Tips

- Zac is able to soak a lot of damage, making them much more viable in the frontline taking damage to protect less tanky teammates.
- Zac has a high rate of healing compared to other champions. They may be good at exchanging hit trades in lane or before teamfights since they can recover through self-healing.
- Zac has a much higher early late game win rate than their late game win rate. Take advantage of this by playing aggressive early on and trying to snowball through kills.
- Zac excells at supporting other champions, and should prioritize helping carrying type champions again kills and snowball.

Zac Runes
Primary Tree

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.
Playing Against Zac
- 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.
