Basic Rules (2014) - Modified
1-level Evocation
As you hold your hands with thumbs touching and fingers spread, a thin sheet of flames shoots forth from your outstretched fingertips. Each creature in a 15-foot cone must make a Dexterity saving throw. A creature takes 3d6 fire damage on a failed save, or half as much damage on a successful one.
Flammable objects in the Cone that aren’t being worn or carried start burning*.
*A burning creature or object takes 1d4 fire damage at the start of each of its turns. As an action, you can extinguish fire on yourself by giving yourself the prone condition and rolling on the ground. The fire also goes out if it is doused, submerged, or suffocated.
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.
