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.
On a failed save, a creature takes 9d6 concussion damage and is deafened for 1 minute.
On a successful save, it takes half as much damage and isn’t deafened by this spell. A creature made of inorganic material such as stone, crystal, or metal has disadvantage on this saving throw.
A nonmagical object that isn’t being worn or carried also takes the damage if it’s in the spell’s area.
You can increase the damage by 3d6 for each additional mana or psi expended.
