Constellation Array

You create three torch-sized motes of star-like radiant energy within range, connected to one another by luminous ethereal tethers into a medium sized array. This array hovers intangibly in space, shedding bright light in a 15-foot radius, and dim light for an additional 15 feet. 

As a bonus action on your turn, you can move the array up to 30 feet to a new spot within range and expend one mote. The mote turns into a beam of radiant power and targets a creature within the radius of light shed by the array. Make a ranged spell attack, and on a hit, the target takes 2d6 radiant damage. Whether you hit or miss, the mote is expended. Each time you expend a mote, the radius of bright and dim light shed by the array reduces by 5 feet. The spell ends early if you expend the last mote.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the number of motes created increases by one for each slot level above 1st. For each additional mote, the radius of bright and dim light shed by the array increases by 5 feet.
