Gameplay
During an ARAM, I had played Thresh and the enemy had a Sion. I don't really have any evidence, but for some reason, (while un-dead) my Thresh Q sorta "fizzled" whenever it hit the Sion. I don't know if it's a Sion un-dead mechanic or not, but it happened about 2 or 3 times. Neither of us had skins if that makes a difference or not.
