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

Two are made per action by using two rune cannonballs and ten rubium splinters at an anvil, requiring level 90 Smithing and granting 30 experience.
