Circadian Blast

A beam of crackling energy streaks toward a creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 Radiant damage between sunrise and sunset, and 1 d10 necrotic from sunset until sunrise. 

The spell creates additional beams when you reach higher levels: two at 5th level, three at 11th level, and four at 17th level. You can focus beams on a single target or multiple targets. On single targets, only make one attack roll. Make separate attack rolls for multiple targets.
