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

Two are made per action by using two mithril cannonballs and ten rubium splinters at an anvil, requiring level 55 Smithing and granting 20 experience.
