2nd Level Arcane, Divine and Primordial Illusion (ritual)
Casting Time: 1 action
Range: 24 sqr. (36m)
Components: V, S
Duration: 10 minute
For the duration, no sound can be created within or pass through a 4 sqr. (6m)-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.
