You create a line of fire that shoots out from your hand. Each creature in a 15 foot line originating from you must make a Dexterity save or take 1d6 fire damage.

The fire ignites any flammable objects in the area that aren't being worn or carried.

The spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
