 Blueprints requiring Nullstones[] Gathering Tips[]
Destroying Asteroids, Red barrels, Metal scrap around wreckages, and Green rifts in any of the Empyrean missions has a small chance to drop Nullstones.
Trivia[]
Nullstones probably have some kind of connection to the Void, evidently as they do not conform with several laws of physics. This would make them have some form of connection or relation to  Argon Crystals and Prisma Crystals as well.
The term null is also a synonym of void.
