i dont ****ing understand it either

Hey ****ing do it once and youll see.

Hmm i say + but i think you got some wrong items.U already thought about the manamune for sion.... its good i think. But buy atmas so fast is mistake in my oppinion

I do not find this build very effective. Armor for sion is a big nono. You need Attack Speed and Damage. Using your ulti is basically having armor. With great attack speed and damage you stun your enemy champion, put on your ulti when your level 18 and you lifesteal 100% and attack speed is maxed. Take a look at my build: Attack Speed Sion
