Song of Sadness
Commonly referred to as Drowstone, Xephagius crystal exudes a dull green light.
The light emitted from the strange mineral is harmful to most all living creatures. However, weapons and armor can be exposed for extended periods to be infused with the light and become more effective.
When exposed to sunlight, xephagius crystal will hiss and literally melt away in a toxic mist that gives off an acrid smell.
