Ironman verdict

Rune 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 8 monsters, 2 recipes and 6 other sources for it.

You can make it yourself with 90 Smithing from Runite bar at a furnace. Each one made gives 50.8 Smithing XP. That is the lowest-level of its 2 recipes. If you would rather kill for it, the lowest-level monster that drops it is Narwhal (level 111), at 2/60, about one in 30 kills. The best rate is from Orca (level 205): 5/92, 24–42 at a time. The 8 monsters we list with a combat level range from level 111 to 235. It also comes from 6 other sources, such as Plundered salvage and Martial salvage.

The material you can buy or make: Runite bar, made with 85 Smithing.

Among the bosses we cover, Shellbane Gryphon drops it.

It is a material in 2 recipes: Rune chainshot cannonball (90 Smithing) and Rune incendiary cannonball (90 Smithing). High Alchemy (55 Magic) turns one into 840 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 660 coins.
