Wondrous item, common
This ink is the only substance that adheres to Kllellek paper, though it can also be used to write on almost any other surface.
Made from a mixture of vvor blood and fluid extracted from a giant spider’s silk sac, the ingredients are bound together through drow magic. Each batch produces four ounces of a viscous, dark gray liquid.
Once applied, the ink leaves a permanent mark, making it prized for inscriptions, identification, and records intended to endure.
Value: 50gp for 4 ounce bottle.
