As two actions, a sudden loud ringing noise, painfully intense, erupts from a point of your choice within 10 meters. Each creature in a sphere centered on that point must make a Fortitude saving throw, which it does with disadvantage if it is made of inorganic material such as stone, crystal, or metal.
On a failure, it takes 8d6 concussion damage and is deafened for 1 minute.
On a critical failure, it takes twice as much damage.
On a success, it takes half as much damage.
On a critical success, it takes no damage.
A nonmagical object that isn’t being worn or carried also takes the damage if it’s in the spell’s area.
A deafened creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
You can increase the damage by 2d6 for each additional mana expended.
