Prismatic Gneiss has fracturized molecule-structure, which explains its unique appearance. It is the most sought after member of the Gneiss family, as it yields 10% more than common Gneiss.
Gneiss is a popular ore type because it holds significant volumes of three heavily used minerals, increasing its utility value. It has a quite a bit of mexallon as well as some pyerite and isogen.
This ore is a compressed and much more dense version of the original ore.
