The drag ball, better known as a trollball or cannon, is the Shaman Item that launches a heavy ball in the direction specified by the arrow drawn on it. Available from the shamans menu are drag balls pre-positioned down, left, and right.
The Drag Balls can be rotated to work in any direction, except straight up, where they just fall down. They lose speed as they are rotated (for example, a drag ball rotated just a little right from straight up will fire/roll leisurely to the right instead of rapidly), which can be beneficial to the shaman that knows how to use that. A drag ball rotated to point perfectly upward can be used to attach to objects without moving them, such as making a wheel for a car.
Drag Balls are commonly used to destroy contraptions such as bridges that are blocking the player's path, and also to blast mice across the map. Another common use of Drag Balls are to launch mice on catapults. However they are often used to troll other mice by pushing them off the map or platform. Drag Balls are a shaman's primary weapon in a shaman battle. Since the removal of the Super Spirit the Drag Ball is the most effective method of "violent" trolling.
 Implement into totems
In totems it was once a popular way to use cannon balls in totems to troll, as super spirits cannot be put inside the totem, and cannons were able to be put it. It was put to an end for some time (Cannons not allowed in totem) but was once more unlocked on 7 March, 2011.
