Band of the Unspoken Vow

This wide copper band is inlaid with faint silver runes. When worn around the neck the band allows the wearer to speak, even if they would otherwise be unable to physically. This projected voice does not function in an area of magical silence or an area created by an antimagic field. In addition, once per day, as an action, the wearer can project their voice with a thunderous boom as if by the thaumaturgy spell, granting yourself or an ally you can see advantage on an Intimidation check.
