You slow the air within a 20 foot radius around a point within range that you can see, making the mere act of drawing breath a laborious task. All creatures within the radius that require breath must make a Constitution saving throw or take 4d10 bludgeoning damage. In either case, all targets within the radius begin Suffocating.

Creatures that are Suffocating in this manner are unable to speak or cast spells with verbal components. All creatures in the radius are resistant to thunder damage. Airborne poisons and spell effects, such as Cloudkill, are nullified within the radius for the duration.

Flying creatures within the radius that have a flight speed as a result of wings are unable to maintain their height, instantly dropping below the area of effect, taking relevant falling damage and becoming prone if they hit the ground. Creatures that hover or have magical flight are unaffected in this manner.
