Amulet of the Architect

This amulet has the appearance of a plain iron compass.

As an action, the wearer can activate the amulet. For 1 minute, the wearer becomes familiar with the layout of any building they are occupying, up to 30 feet from their location, centered on the wearer. This reveals any nearby passages or rooms; secret, concealed, or hidden doors, or if another level is above or below their location. This ability does not work outdoors. 

This ability recharges after a long rest.
