Rune incendiary cannonball

Description
The Rune incendiary cannonball is a members only item in Old School RuneScape. You fire it from a cannon during boat combat. It deals the same damage as a normal rune cannonball, but it also burns the target. The burn effect gives you extra damage over time, so it is a strong pick for sea fights.
You can make these cannonballs at an anvil. Each action uses two rune cannonballs and ten rubium splinters, and it gives you two rune incendiary cannonballs. You need level 90 Smithing, and you must finish the Pandemonium quest first. Each action gives 30 Smithing experience and takes 1.8 seconds.
These cannonballs are tradeable and stackable, so you can carry a big supply without using up bank or bag space. They weigh nothing at all. They cannot be equipped or turned into notes.
If you want more damage in boat combat, this ammo is a clear upgrade over plain rune cannonballs. You get the same hit power plus a burn on top. Stock up and keep your cannon loaded for your next fight at sea.
