Iron incendiary cannonballs are items that can be fired from a cannon during boat combat. They deal the same amount of damage as iron cannonballs, and apply burn to the target as well.

Two are made per action by using two iron cannonballs and ten rubium splinters at an anvil, requiring level 20 Smithing and granting 10 experience.
