Barrel

The barrel is an explosive entity, it can be ignited using a torch, which makes it explode, the explosion destroies any token or tile on the same square as the exploding barrel (unless they are made form an explosive resistant meterial). The barral can also be used to load cannons, if your inventory contains one or more barrels when mounting a cannon the barrels will be "absorbed" by the cannon and its load will increase a corresponding amout to the barrels load. If a barrel is launched by a catapult it will explode when it lands, it's the only item that does something when it lands after a catapult launch.

Trivia
The original idea of the barrel was that it only should be used to load cannons.
