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 Kayn

How to counter and exploit weaknesses

  1. Dodge his Blade's Reach

    Dodge Blade's Reach (W): Umbral Trespass (R) can only target a champion he just damaged, and this ranged hit is how he marks you from range.

  2. Save your CC for his E

    If you have CC, land it during Shadow Step (E): once immobilized, he loses the spell and can't move through walls anymore.

  3. Save your spells for his exit

    Don't cast your spells during Umbral Trespass (R): hidden inside your ally, he's untargetable. Save them for when he bursts out.

  4. Ward your jungle too

    Ward your jungle too, not just the river: Shadow Step (E) lets him go through walls and show up from unexpected paths.

  5. Pressure him before he transforms

    Pressure him before his transformation: until he picks Rhaast or Shadow Assassin, The Darkin Scythe (passive) gives him no healing or bonus damage.
