Spell Scroll of Silence

This scroll holds the power to cast the spell
silence without material components.
For the duration, no sound can be created within
or pass through a 20-foot-radius sphere centered
on a point you choose within range. 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.
