Miser’s Mask

Wondrous item, common (requires attunement)

This wooden mask depicts the sunken face of a miser with an upturned nose. The mask grants the wearer blindsight of 30 feet, but they can use it only to sense coins and gems. Each type and quality of gem has its own unique aura to the wearer, granting advantage on checks made to ascertain the value or determine the properties of gems.
