Common Scraps
Common Scraps is one of the materials obtained by salvaging items in the salvage cube. Materials are used by the Artisans to craft new items. Materials are also required for the training the Artisans to do level up.
There may be other purposes for materials as well, but none have yet been revealed.
Common Scraps are obtained from nearly everything recycled in the Salvage Cube, and are in turn needed in every recipe.
