I saw a nice creative Sion build
He was top again our Jax. He went with Glacial augment. Everytime he would die, he would cast Righteous Glory and it would automatically shoot that cold laser and slow them so his passive would hit 4-5 times before dying, most of the time bringing one of my ally down.
Our Jax had major time dealing with him and was on the verge of giving up
When he would get ahead, he would simply use righteous glory to slow them combined with that glacial augment.
It looked nice
