Soul Vindication

You let out a scream that spreads in a 15-foot cone multiplied by your Constitution modifier (minimum 1). Creatures in the area must make a Constitution saving throw. On a failure, they take 12d6 vibrational damage and are Stunned until the end of their next turn. On a success, they take only half the damage.

An affected creature that took thunder or vibrational damage within the last two turns makes the saving throw with disadvantage, and on a failure gains 1 level of Exhaustion and falls Unconscious instead of Stunned.
