Divine Sutra Arrow

A yellow flaming arrow manifested from the depths of the spirit plane of Edenia fires out from you. It is five feet wide and goes 100 feet. When it reaches the end of the 100 feet or directly impacts a target, it explodes in a ten foot radius. Creatures in the path of the arrow or caught in the explosion must make a DEX saving throw. They take 8d6 fire damage on a failed save, half as much on a successful save.

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

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
