Amulet of Silence

When in use, nothing within a 20 foot of the holder of this amulet can cause any sound at all, except for the holder. Any creature or object entirely inside the sphere is immune to thunder damage, and creatures are deafened while entirely inside it. Casting a spell that includes a verbal component is impossible there, except by the amulet's holder.

To activate the amulet, the holder must cup it using all their available hands.
