Vacuum Aura (DoS:2)

For the duration, the air is under your control in an aura with a 15-foot radius. Until the spell ends, the aura moves with you, centered on you. No sound can be created within or pass through the aura. 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 inside the aura. You can use a bonus action to cause one creature in the aura to make an Intelligence saving throw. On a fail, you cause the target to believe they are suffocating, taking 3d6 psychic damage, and automatically fails to maintain concentration on any spells they were concentrating on. On a success, the target takes no damage, and their concentration is unaffected.
