Playing against Mordekaiser
How to counter and exploit weaknesses
Buy a QSS to escape his R — it's essential for carries who don't want to be isolated.
Kite him: Mordekaiser is slow with no dash. Ranged champions and slows counter him well.
His E (pull) has a visible delay: sidestep when you see the animation.
% max HP damage counters him since he builds HP: Vayne, Kog'Maw, and Liandry's are effective.
