This button-sized, black half-sphere appears to be made of ebony or jet.

If you spend 1 minute attuning yourself to a scrying beacon, you can choose for the next clairaudience/clairvoyance spell you cast to be centered on the beacon, as long as you are within 1 mile of it. Once this power has been used, the beacon becomes dormant until you attune yourself to it again.

Prerequisites: Craft Wondrous Item, clairaudience/clairvoyance.
Cost to Create: 375 gp, 30 XP, 1 day.
