You unleash a torrent of draconic energy in a 30 foot cone centered on yourself. all creatures within the area must make a constitution saving throw, taking 4d4 force damage on a failed save, or half as much on a successful one.

at higher levels: when you cast this spell using a spell slot of 2nd level or higher, increase the spell's damage by 2d4 for each spell level above 1st.
