Playing as Mordekaiser
Tips to maximize your impact
- Hit a lone enemy with your Q
Aim Obliterate (Q) at a lone enemy: if only one enemy is hit, the damage increases.
- 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.
- 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).
- 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.
- 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
- 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.
- 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.
- 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.
- 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.
- 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.
