Ship Cannon

Ship cannons are smaller versions of the siege cannon. The smaller size allows them to be used on sailing and airships, but with a significantly reduced range of attack. Damage output is not affected by the size change. It takes one action to load a ship cannon, and one action to aim and fire. A creature must succeed a DC 10 Strength (Athletics) check to insert an iron ball into the cannon.
