DrakenFlame

A 15 ft cone emanates from you in a direction you choose. Each creature in the cone must make a Dexterity saving throw. A creature takes 1d6 fire damage on a failed save, or half as much damage on a successful one.

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.
