Sion doesn't need abilities [GAMEPLAY]

I was playing a "poro King" match when all of my abilities stopped working. I furiously smashed my keys like Sion smashes his enemies but alas it did not work. Next, I tried to reset my key bindings like Zilean resets time after a champs death, still nothing. Finally, I used my brain like Heimerdinger and left the game...only to return of course! Ha! Thought I went afk, nope not this guy! After leaving the game and coming back, all my abilities worked again! Sorry about the long drawn out description and solution.

TL;DR If your abilities don't work, leave the game and reconnect. That's what worked for me
