Amulet of the Sonant Imposter

This brass clockwork amulet has three primary gears that tick along silently, framed by an alighting sparrow. While wearing this amulet, you can perfectly mimic the normal voice of another humanoid. You must have heard the person speaking for at least 1 minute. A successful Wisdom (Insight) check contested by your Charisma (Deception) check allows a listener to determine that the effect is faked. If the wearer of this amulet changes, it forgets the voices it has learned.
