Cryotheum Dust is a type of dust added by Thermal Foundation. It is created from Redstone, Snowballs, Niter and Blizz Powder. The material is capable of cooling things down to extreme temperatures very quickly. It is the water elemental material.
Cryotheum Dust has very few uses. It is an ingredient in crafting some of the highest Level Augments. The most important use, however, is melting the material down into Gelid Cryotheum, which has more uses.
