Ever watched the show Dragon Ball Z? Well it's pretty much self-explanatory. Make sure you're well aligned with your opponent before using this weapon.
The worm fires a slightly huge purple fireball and sends it towards the enemy throwing them back with a fair amount of force. Be sure to be fairly close to your opponent before using this for the fireball only travels a certain amount of distance.
Also, since it's damage is rather weak with a max damage of 30, I advise you use this weapon to worms who are near the edge of the terrain to ensure they will be knocked off. Exceptions can be made on several different occasions.
