Agari's Sound Burst

You emit a concussive sound wave, a cone of noise emanating from you up in the air towards a point within range, damaging creatures within the area. Each affected creature must make a Constitution saving throw.

On a failed save, a creature takes 1d8 thunder damage and is stunned.

On a successful save, the creature still takes the full damage, but isn't stunned. An affected creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Creatures without hearing are not stunned, but still suffer the damage.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d8 for every second level.
