Ironman verdict
Rune incendiary cannonball is a members item. Other players trade it, but an Ironman cannot use the Grand Exchange or trade, so you get your own. We list 1 recipe for it.
You can make it yourself with 90 Smithing from 2 × Rune cannonball and 10 × Rubium splinters at an anvil. Each one made gives 30 Smithing XP.
The material you can buy or make: Rune cannonball (2 needed), made with 90 Smithing.
No recipe in our data uses it as a material. High Alchemy (55 Magic) turns one into 1,680 coins. Each cast uses a nature rune, 180 coins from a rune shop, and five fire runes that a fire staff replaces, so an alch nets about 1,500 coins.
