Draconic Wave

You produce a bead of energy, related to the dragon scale you use to Chanel this spell, and then release it in a 10-foot cone or a line, your choice. Each creature in that area must make a dexterity saving throw, taking 2d10 damage corresponding to the dragon scale on a failed save, or half as much damage on a successful one.

At higher lvl

When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d10 and the range increases by 10 ft for each slot level above 1st.
