So i love trying non-meta shiz. i think its a blast to do something totally strange in a game, and make it work! So here is the thing, i know that this isnt extremely viable, so im not looking for someone to tell me im an idiot. but lets just say we were to try ap sion. How would you build it, and where would it be most effective? I know AP sion used to be a thing before he was reworked forever ago, but i want to bring him back haha.
So basically you're looking at an AP Bruiser like Aurelion Sol. You should probably rush RoA and then get a Liandry's. A Rylai's could be cool, but it really only helps your shield, so I'd skip it. After that a Zhonyas/Abyssal would probably be wise, followed by standard Deathcap/Void Staff EDIT I totally forgot about Protobelt, which could also be really cool.
I've done it before. It's like Pre-rework AP Sion except it requires more skill. Falls off just like OLD AP Sion tho but not as hard.
Rylais, lich bane, rod of ages, and protobelt you can use while in your passive
