The up B can be jumped off of for extra height. Also if you use the move mid-air the boxes Have gravity. As you can see, the move disappears after a short amount of time. During the time it is active, it works like a wall for other opponents; opponents can’t walk through it and can wall jump off it. (Scroll down for more) The Neutral B throws a superball! The superball bounces off everything that counts as a wall until it hits someone or flies off stage. The move has a 5 second cooldown. Since it bounces off silvic’s up B since it counts as a wall, I can only imagine what chaos would occur if Everyone played as Silvic.
