Item description:
A small, flat bottle filled with a vaguely ominous black liquid. You're fairly sure that's a Tenabre Fox on its faded label. It blends into even the slightest shadow, and if not for its bell and collar, you probably would have lost it by now.
Item use:
When fed to a specific creature, it transform it into a Tenabre-like version of itself. The creature will have a bare skull, glowing blue eyes, a black ruff around its neck, and varying amounts of black streaked and blotched across its pelt.
Maybe this potion could work on multiple species, including more common ones like Hippocampii and Phoenixes so that interest in those will be increased?
Also, perhaps it could strip nearly all of the flesh from a Decessus and leave it with a mostly bare skeleton and little bits of black hide, since Decessii don't need their organs and would look really cool as skeletons.
Maybe it could even reverse-Tenabre a Tenabre Fox by turning it into essentially an Arctic fox- blue eyes, skin and flesh over the skull, and a white pelt.
