You create a stella constellation in the space of a creature within range. Make a ranged spell attack against the creature to assail it with the radiation of the stars. On a hit, the target takes 1d8 radiant damage, and it has disadvantage on his next attack roll until the start of your next turn. Until then, the stella constellation clings to the target.
This spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8)
