The Artillery dice is rolled twice when a cannon is fired, so there are two chances of rolling a Misfire result. However, the two results will be different. If a Misfire result is rolled on the first dice, the cannon has literally misfired and may explode. If a Misfire is rolled on the Bounce roll then this merely indicates that the ball has stuck in the ground and does not bounce.

If a Misfire is rolled as the cannon is shot then consult the Misfire chart.
