Amulet of Sardior

This ruby amulet is inlaid with gold and shaped like a dragon's head. As an action, you can use the amulet to help you locate Aberrations until the end of your next turn. If any Aberrations are within 1 mile of you, the amulet emits a low humming tone for a moment, and you know the direction of all Aberrations within that range. Once this property is used, it can't be used again until the next dawn.
