Vobi

Vobi
Vobi is a sprite researcher and scientist. In her Faustian quest for knowledge, she made a bargain with a fiendish warlock. After completing the ritual to turn her into an immortal, eidetic, archive, the warlock ran off with the ring that she was housed in, and Vobi learned many dangerous and arcane secrets while she passed from owner to owner.

Owners

 * Rowarin
 * Many, many others
 * Berenice, Brine, Nestor, and Kith (willingly)

Magical "Item" Properties

 * Language. The bearer is able to speak and understand Sylvan.
 * Beacon. The wearer can use a bonus action to cause the item to shed bright light in a 10 foot radius, and dim light for an additional 10 feet, or to extinguish the light.
 * Requires attunement for telepathic communication.
 * Normal hearing and vision out to 30 feet.
 * Possessive. Deals 1d4 psychic damage if the wearer removes the ring once attuned, or 3d4 if someone other than the wearer tries to remove the ring.  (Nestor once equated this to Vobi bitchslapping a person.)
 * Metamorphic. The item periodically and randomly alters its appearance in slight ways.  The wearer has no control over these minor alterations, which have no effect on the item's use.
