Sion's abilities

Passive, spells and ultimate

Glory in Death (P)

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 Mordekaiser

Tips to maximize your impact

  1. Hit a lone enemy with your Q

    Aim Obliterate (Q) at a lone enemy: if only one enemy is hit, the damage increases.

  2. Activate your passive, then stay close

    Hit champions or monsters three times, then stay close: Darkness Rise (passive) then surrounds you with a damage aura and gives you move speed.

  3. Pull them into your Q

    Pull your targets into the Obliterate (Q) zone with Death's Grasp (E): each spell that hits also counts toward Darkness Rise (passive).

  4. Tank with Indestructible

    Cast Indestructible (W) when you're taking damage: it turns stored damage into a shield, and a recast converts part of it into health.

  5. Isolate the carry in your R

    Cast Realm of Death (R) on their carry, or their jungler near an objective: you isolate them with you, steal part of their stats, and keep them if you kill them.

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.
