Twin Gods

You petition the twin gods Artemis and Apollo to aid in your attack.  One target within range is hit simultaneously by Bathed in Moonlight and Basking in Sunlight.

Bathed in Moonlight:  A silvery beam of pale light shines down in a 5-foot-radius, 40-foot-high cylinder centered on a point within range. Until the spell ends, dim light fills the cylinder.

When a creature enters the spell's area for the first time on a turn or starts its turn there, it is engulfed in ghostly flames that cause searing pain, and it must make a CON saving throw. It takes 2d10 radiant damage on a failed save, or half as much damage on a successful one. A shape-changer makes its saving throw with disadvantage. If it fails, it also instantly reverts to its original form and can't assume a different form until it leaves the spell's light.

Basking in Sunlight:  Three rays of fire appear and circle the column of moonlight.  When cast, one ray immediately flies at the target, make a ranged spell attack.  On a hit, target takes 1d8 fire damage.  Each of the remaining 2 rays fires at the beginning of the caster’s subsequent turns, before their action.  Follow the same procedure as the first ray.
