Destiny's Umbralight Spiral

You create two spiraling streams of energy, one composed of lace-like light and another composed of writhing darkness. You can volley them each at the same target, or separate.

For each ray, make a ranged spell attack against the target. On a hit, the first ray deals 2d6+2 radiant damage, and the second ray deals 2d6+2 necrotic damage. 

At Higher Levels: When you cast this spell using a spell slot of 3nd level or higher, the damage increases by 1d6 on each ray for each slot level above 1st.
