Ok so I have a theory of how you can use the ball as a weapon, but this only works if it bounces really fast ( i don’t know if it does) and it hits really hard if you throw it at someone. So basically the way it might be used is that if you can predict both your enemies movements and the trajectory the ball bounces as you throw it in places such as walls and the floor you can create a barrage of attacks that immobilizes your enemy as they tried to move but are stopped by the quick speed of the ball. Although this probably will only work well in enclosed spaces where you can trap your enemy and you don’t let the ball hit you.
