Boneflux

Boneflux is a welding flux created by blessing a White gold-infused bonemeal mixture, requiring level 70 in Smithing, Crafting and Prayer. Using higher level bonemeals results in greater amounts of Boneflux.

The Boneflux is used to subdue the trapped spirits in Necrolith ore, sealing them off long enough for a smith to be able to drive out impurities and melt the ore down into a bar.
