Spectral Mineral Powder

 is a Crafting Material in Fortnite: Save the World that was given to players by mistake when it had not been released yet. It is currently unobtainable and is not used to craft any weapons. Epic Games had stated it would be used for Tier 6 Crafting if that would come out, and it would have been found from Twine Peaks by destroying rocks.

Its design is similar to that of the Shield Potion in Fortnite: Battle Royale.
