• You can sense the difference in/of vibration between different materials  eg. You can sense hidden passages.  This can be assisted by a successful perception or investigation check.

• This ring is a cursed item. Due to grief that has taken root in Lady Giovanna's heart at the loss of her beloved Constance, the wearer must pass an initial DC13 Wisdom/Saving throw, or lose 1 sanity point. For every gemstone gained back, the DC of the Wisdom/Saving throw increases by 1. If the wearer loses 5 sanity points, they are plunged into Lady Giovanna's grief, and experience such deep despair that they are incapacitated until healed by a Greater Restoration spell
