Bone Spikes

A sudden loud ringing noise, painfully intense, erupts from a point of your choice within range. Each creature in a 10-foot-radius sphere centered on that point must make a Constitution saving throw. A creature takes 3d8 thunder damage on a failed save, or half as much damage on a successful one. 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.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.

You summon bones from the ground to pierce an area you can see within range. Shattered bones pierce through the earth in an area within a 10ft. radius of that point. Creatures within that area must make a dexterity saving throw, taking 1d10 piercing damage on a failed save, or half a much damage on a successful save. When a creature enters the area for the first time on a turn or starts is turn in that area, it must make the dexterity saving throw, taking the same amount of damage rolled during the initial casting. While the spell lasts, the affected area is considered difficult terrain. 

At Higher Levels: When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d10 for each slot level above 1st level.
