Wandering Star Motes

This is a conversion of the Wandering Star Motes spell from Pathfinder 1e

Choose one living creature within range. You create sparkling motes of bright light that shoot toward the target and swirl around them in a complex pattern. The pattern sheds bright light in a 30 ft. radius and dim light for an additional 30 ft.

Any attack roll against an affected creature has advantage if the attacker can see it, and the affected creature can't benefit from being invisible. At the end of each of the target's turns it makes a Charisma saving throw. On success or when the affected creature is reduced to 0 hit points, the motes jump to the nearest creature within 30 ft. that is hostile to you and hasn't been affected by this spell. If there are no creatures within range for the motes to jump to, the spell ends.

A cleric who worships Desna can replace one of their 4th level Domain spells with this spell. The decision to substitute a Domain spell must be made upon gaining a new level of cleric, but you can change your decisions on the matter when you level up again.
