After being killed, Sion will temporarily reanimate with rapidly decaying Health. His attacks become very rapid, heal him, and deal bonus damage based on his target's maximum Health.

Playing as Zac

Tips to maximize your impact

  1. Smash them into each other

    After Stretching Strikes (Q) on one enemy, hit a second enemy with your auto: you fling them into each other, and if they collide, they and those nearby take damage.

  2. Pick up your Goo

    Pick up the chunks of Goo you shed when your spells hit: Cell Division (passive) heals you for each one, and Unstable Matter (W) comes back 1 second sooner.

  3. Charge your Slingshot out of sight

    Charge Elastic Slingshot (E) from the fog of war: the enemy has less time to react, and the longer the charge, the longer the knock-up on landing.

  4. Bounce into the middle of them

    Cast Let's Bounce! (R) into the heart of their team: the first bounce knocks back each enemy hit, the following ones slow them, and you can cast Unstable Matter (W) at the same time.

Playing against Sion

How to counter and exploit weaknesses

  1. Leave his Smash area

    Leave the area while he charges Decimating Smash (Q): past 1 second of charge, the hit applies a knock-up and a stun, for up to 2.25 seconds.

  2. Break his shield

    Break the Soul Furnace (W) shield before he detonates it: he can only trigger it if the shield still holds.

  3. Dodge his charge sideways

    Step to the side of Unstoppable Onslaught (R): he turns poorly once it's launched, and his charge stops on the first champion hit.

  4. Back off when he comes back to life

    Back off as soon as he dies: during Glory in Death (passive), his autos are much faster and deal damage based on your max health, but his health drains fast.
