Aurelion Sol and Braum
So Aurelion Sol's Q disappears when it reaches a Braum shield rather than detonating and stunning Braum. I know this is a bug because Aurelion Sol's Q has the same mechanic as Anivia's Q and Anivia will still stun Braum when he stops her Q but for Aurelion Sol the Q just disappears completely (which makes even less sense with a door-shield being able to stop an entire universe colliding on him, sure its called Unbreakable but come on man).
This will happen 100% of the time unless you manage to detonate before it hits Braum.
