Burning Hands

A thin sheet of flames shoots forth from
your outstretched fingertips. Each creature
in a 15 ft cone makes a Dex save. A creature
takes 3d6 fire damage on a failure, or half as
much on a success. The fire ignites
flammable objects in the area.
At Higher Levels. For each extra spell slot,
the damage increases by 1d6.
