Ink, Ghost

Source Seekers of Secrets

Pale blue when wet, ghost ink quickly dries to near transparency 1 minute after application. Ghost ink is most often used to blaze trails and mark locations in a subtle manner. The pigment shines with a warm red glow under the light shed by fire beetle glands and sunrods, but under optimal normal conditions (such as a pale surface like parchment or a plaster wall) can only be noticed with a successful DC 25 Perception check. One vial of ghost ink is the size of a potion vial and sufficient for writing a page’s worth of characters.
