Amplify

For the duration, all sound within a 20-foot-radius sphere centered on a point you choose within range is amplified. Creatures outside the sphere gain a +10 bonus to Wisdom (Perception) checks to hear sounds created within the sphere. Creatures inside the sphere do not perceive sounds to be any louder than usual. Additionally, all thunder damage originating from inside the sphere is doubled.

If this sphere’s radius touches or overlaps the radius of a silence spell, both spells end instantly.
