You conjure an almost imperceptible web of sonic energy that forms a vertical screen--up to 90 feet long, 30 feet high, and 1 inch thick--centered on a point you can see within range. Alternatively, you can shape the screen into a sphere up to 30 feet in diameter centered on a point you choose within range. The screen remains in place for the duration. If you position the wall so that it passes through a space occupied by a creature, the spell fails, and your action and the spell slot are wasted.
Each creature that starts its turn in the screen or that passes through it during its turn must make a Constitution saving throw. The creature takes 8d6 thunder damage on a failed save and is deafened for 1 minute, or takes half as much damage on a successful one.
On a critical failure, a creature passing through the screen will have its speed drop to 0 for the rest of the turn. This stops any movement they may have been taking.
When a creature passes through the screen for the first time, a loud boom, audible from as far away as 300 feet, emanates from the point of contact. While the spell cannot be perceived visually, it does emit a low hum that can be detected with a perception check equal to the spellcaster's level.
This screen is removed by a dispel magic spell or a similar spell of equal or higher level that can end spells and magical effects.
