I gotta say, i didn't knew about this, until yesterday, i was practicing s3~fbrc~f4~flame aura combo, and then at some point i got an X-ray out of holding out the fireball, i though i run canceled, so immediately went to look for the results of it.
Many may already be aware, but you can possibly bait some stuff with a raw fireball and X-ray punish it, specially to close the game.
