Combos and how to play

Zac is an elastic tank: every ability that hits makes him lose a bit of himself that he absorbs to heal, and on death he splits into 4 blobs that try to recombine. Stretching Strikes grabs and slams two targets, Unstable Matter damages based on max health, Elastic Slingshot launches him, and Let's Bounce! bounces four times while knocking up.

When: Two enemies are close to each other.

Stretching Strikes grabs an enemy then, if you attack another one, sends the two targets into each other.

The second life

W

When: You take lethal damage.

Cell Division splits you into 4 blobs that try to recombine; if any remain, you come back to life. This ability has a 5-minute cooldown.

Laning phase

Pick up your bits to heal. Stretching Strikes grabs an enemy then, if you attack another one, sends the two targets into each other.

Common mistakes

• Leaving the bits on the ground: they are your healing.
• Forgetting that the second life is available every 5 minutes.
• Using Elastic Slingshot with no direction: it is a movement ability.

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.
