Ability details

  • 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.

    Passive — never cast

  • Stretching Strikes

    Zac stretches an arm, grabbing an enemy. Attacking a different enemy will cause him to throw both targets towards each other.

    Cooldown 14/12.5/11/9.5/8sRange 800

  • Unstable Matter

    Zac explodes outward towards nearby enemies, dealing a percentage of their maximum health as magic damage.

    Cooldown 5sRange 350

  • Elastic Slingshot

    Zac attaches his arms to the ground and stretches back, launching himself forward.

    Cooldown 21/18/15/12/9sRange 300

  • Let's Bounce!

    Zac bounces four times, knocking up enemies hit and slowing them.

    Cooldown 120/105/90sRange 300

Counter plan — how to beat Zac

  • Build percentage damage — flat penetration falls off against the stats it stacks

  • Avoid extended fights — its sustain grows with every trade it survives

  • Punish the cooldown — Zac is exposed while its rotation is down

  • Ward the flank — vision is what turns its best opening into a worse one

  • Respect the spike — Riot rates the kit 8/10, so a practised player gets more out of it than the average

Methodology

Data window
512,340 games on patch 26.16, Ranked Solo/Duo, NA. Last refreshed 20 Aug 2026.
Rank aggregation
Emerald+ and above, pooled. Splitting further leaves samples too small to separate a real effect from noise.
Role assignment
A champion is filed under the lanes it actually plays, not the one class it belongs to — which is why several appear in two.
Counters
A matchup, not a tier gap: how this champion does into that one specifically, over that pairing’s own games.
Minimum sample
The confidence indicator beside every rate is driven by how much of the window this champion appears in. A low reading means read the figure loosely, not that it is wrong.
Why a build is not a cause
The best-scoring build is the one the best-placed players happened to take. Correlation is what a rate can show; it is not evidence that buying those items caused the wins.
Where the numbers come from
Names, classes, lanes, abilities, items and runes are Riot Data Dragon. Win, pick and ban rates are derived samples — Riot publishes none of them, and nothing on this page presents one as measured.
