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 Olaf

How to counter and exploit weaknesses

  1. Dodge his axe

    Dodge Undertow (Q): it's his only slow, and without a dash, he can only reach you on foot.

  2. Trade while his axe is away

    Take a trade when his axe has landed far from him: until he picks it up, Undertow (Q) keeps its 9-second cooldown.

  3. No long trades when he's low

    Avoid long trades when he's low on health: Berserker Rage (passive) gives him attack speed and life steal based on his missing health.

  4. Save your CC for after Ragnarok

    If you have CC, save it for after Ragnarok (R): while it lasts, no CC stops him, and it has a 100 to 80 second cooldown.
