A more solid form of protomatter, primal essence resembles sand, though smooth and polished. Individual grains are perfectly spherical, and appear to be made of solid mercury.
A pinch of primal essence costs 150 gold. One pinch may substitute for any material component costing 100 gold or less. Multiple pinches can stand in for components costing more than 100 gold.
