4th-level evocation
Choose a point on a solid surface on the ground within range that you can see, which becomes illuminated in a warm red glow for the duration, shedding dim light in a 10-foot radius. When you cast this spell, and as an action on each of your turns until the spell ends, you can unleash a torrent of fire from the ground in a 10ft radius, 120ft high column centered on the point you chose. Each creature within this area must succeed on a Dexterity saving throw or take 5d8 fire damage and become knocked prone. A creature that succeeds on its saving throw takes half as much damage and isn’t knocked prone.
The fire ignites flammable objects in the area that aren’t being worn or carried.
