Disruptive Wave

By flowing magical energy into your neck, you focus your magic through your vocal cords and let a disruptive wave through your mouth.

Each creature in a 15-foot cone must make a Dexterity saving throw. A creature takes 3d6 plasma damage on a failed save, or half as much damage on a successful one.

The wave short-circuits living machinery if near death in the area.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
