Enialeigh's Blazing Arrow Barrage (Arteria)

You conjure a rain of fiery arrows that fall upon a point you choose within range. Each creature in a 30-foot-radius, 40-foot-high cylinder centered on that point must make a Dexterity saving throw. On a failed save, a creature takes 10d6 fire damage and is ignited, taking 1d6 fire damage at the start of its next turn. On a successful save, a creature takes half as much damage and is not ignited.

At Higher Levels: When you cast this spell using a spell slot of 7th level or higher, the damage increases by 1d6 for each slot level above 6th.
