Wall of Sound

A vibrating wall of pure condensed sound appears at a point you choose within range. The wall appears in any orientation you choose: horizontally, vertically, or diagonally. It can befree floating, or it can rest on a solid surface. The wall can be up to 60 feet long, 10 feet high, and 1/4 inch thick. The wall doesn't block line of sight, but sound, small or tiny creatures, and small or tiny objects can't pass through it. Medium or larger creatures can only pass through the wall when using the Dash action. When something pass through the wall (a creature or an object), each creature within 10 feet of the wall must make a constitution saving throw, taking 4d6 thunder damage on a fail, or half as much on a success.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6 for each slot level above 4th.
