When firing from the cannons you may fire a single cannonball from any one of the available cannons and roll the
Attack die to resolve its
Damage. Then, you may repeat this process of firing cannonballs one at a time as many times as you have cannonballs. Cannonballs cannot be combined by shooting multiple at the same time to try and do extra
Damage in a single instance. You are also not required to choose if you are going to use another cannon shot until after the previous cannon has resolved.
