If the clamor starts its turn in an area under the effect of silence, it takes 13 (3d8) force damage, and it must make a DC 15 Wisdom saving throw or become frightened for 1 minute. While frightened, it must use its action to Dash away from the area of silence. If it begins its turn further than 60 feet away from the area of silence, it can repeat the saving throw at the end of each of its turns, ending the effect on a success.
