It's like a mini version of the ball vehicle. You hold it in your hand, and you throw it at someone, and they can catch it by clicking right before it hits you. If it hits you, you get stunned for 3 seconds. The ball would be bouncy, and would bounce everywhere. It's not meant to kill blockheads. Both players need to have at least one weapon slot empty to hold the ball. Once you throw it, it goes out of your inventory and you need to get another one. It'd be fun playing catch in the middle of a battlefield.
