You fire an angelic arrow from a bow made of light that materializes in your hands. Make a ranged spell attack against a creature within range. On a hit, the target takes 4d10 force damage, and until the spell ends, it becomes vulnerable to one of the following damage types of your choice: acid, cold, fire, lightning, necrotic, radiant, or thunder.   If a creature has immunity to the selected damage type, it instead has resistance to that type for the duration; if a creature has resistance to the selected damage type, it loses that resistance for the duration.
