Conqueror Kassadin
Bear with me as we all know Kassadin is not a top lane bruiser, but I think the keystone has potential on him. In my opinion precision is already the best primary tree to run on Kassadin for the free ult spams in late game fights and fleet footwork is the usual keystone. But, imagine late game having a free 20% true damage. I believe the combination of free ult spams and free true damage wouldn't just make Kassadin a viable assassin but a champ that can shred tanks and bruisers alike. Let me know what you could see as potential pitfalls.
