Burning Ground

You cause the burning wrath of nature to appear on the ground within 150 ft. of you. At that point a 5 ft. tall and 25 ft. wide cylinder of fire appears. Each creature in that area must make a Dexterity saving throw. On a failed save, a creature takes 4d6 fire damage, or half as much damage on a successful save.
(Any flammable object in the area will catch fire) The spell is active as long as the caster maintains concentration on the spell up to 1 minute.

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.
