Mordekaiser's Ultimate now applies grievous wounds

Metal will do that

It should to begin with, your friggin soul is getting drained from you, isn't it?

I agree. It would increase Mordekaiser's options for summoner spells.

Don't you have for that job?

Morde buffs?

Ult also should drain their movement speed x second, think of Rocksolid's stone wheel.

W gives movement speed for it's duration.

:D
