Seriously, mang, I don't know why the fk he is so strong, but HOLY.
He can pubstomp so easily.
They got a fed adcarry? No problem.
They got a lot of CC? No problem.
They got a Cassiopeia? No problem, 370 ms, good luck with skillshots.
They got an assasin? Who the fk cares, Always shield, never die!
They want to kill you? Good luck with that. I'm behind 7 proxyshields.
The thing is that most people build him like a squishy mage, instead of an AP bruiser. And "Spirit of the" items are really good on Mordekaiser.
Yet General Discussion just complains about lux and puny champions, you should be ashamed
Edit: The build I use on Mordekaiser is Spectral Wraiths, Boots of preference, Sunfire cape, Elder Lizard, Spirit Visage, and another item. Cheap, strong, and effective
