Not everyone builds alot of MR, but if you want to you could switch up the quints for magic pen O.o
I did state this is my first guide and I want people to help me improve a bit.
I will update new stuffs when I try them out though.

Not enough detail. Also you had NO MAGIC PEN AT ALL. if someone decides to get a banshees or a AP defensive item of any sort, 50% of your damage is gone. Anyways i see no synergy anyways.

thanks. I think its a good idea cause no one has tried it. it gives nice survivability because of the ap buffing up the shield whilst still maintaining a high dps

good idea ;]

good look

well i wanted ghost and surge but surge isn't set up on moba yet so i can't click it. and actually my build works well. try it before you bash it please ^^

I'm sorry to say it, but in my opinion sion can only be good AD or AP, no way Hybrid..
furthermore, your spells are made only to escape. Sion needs either Ghost-Exhaust or Flash-Ignite...
