Dark Reaver Powder toxin is derived from the dark reaver mushroom, which is found deep in the underdark, far below the mountains and forests that you and I call home. It feeds off the fecal waste from Bolrage cave trolls. The dark reaver mushroom can grow up to three feet high, with a cap of approximately five inches in width, and gives off a bioluminescent light. The mushroom is harvested right at its peak when the cap turns a dark yellow. Once the mushrooms are harvested, they are smoked, dried, and carefully sorted by potency. Once we have separated them my apprentices begin the process of grinding the toxins and purifying them. Corked and sealed in a vial, to preserve its potency. Sufficient for all magical potions, magical studies, and spell components.
