Zac's abilities

Passive, spells and ultimate

Cell Division (P)

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.

Playing as Sion

Tips to maximize your impact

  1. Last-hit everything for max health

    Last-hit minions and monsters for Soul Furnace (W): each kill permanently gives you max health, more on champions, large minions and large monsters.

  2. Slow before your Smash

    Slow your target with Roar of the Slayer (E) before charging Decimating Smash (Q): they're less likely to get out of the area.

  3. Charge your Smash for at least 1 second

    Charge Decimating Smash (Q) for at least 1 second: below that, the hit only slows, and beyond it, the knock-up and stun last longer the more you charge.

  4. Keep hitting after you die

    After you die, hit the nearest champion: during Glory in Death (passive), your autos are much faster, heal you and deal damage based on their max health.

  5. Engage or roam from far away

    Cast Unstoppable Onslaught (R) from far away to engage or roam: unstoppable for 8 seconds, you stun longer and hit harder after a long charge.

Playing against Zac

How to counter and exploit weaknesses

  1. Step on his Goo

    Walk over the chunks of Goo he sheds: you destroy them, and Cell Division (passive) can't heal him with them anymore.

  2. Spread out after his Stretching Strikes

    If Stretching Strikes (Q) grabs you, spread out from your allies and minions: his next auto on one of them flings you into each other.

  3. Interrupt his Slingshot

    If you have a stun, a silence, a root or a knock-up, use it while he charges Elastic Slingshot (E): his charge is interrupted before the jump.

  4. Kill all his bloblets

    When he dies, kill his bloblets: Cell Division (passive) splits him into 4, and if any remain, he comes back to life. This passive has a 5-minute cooldown.
