When you make an attack or damage roll that is improved by your Sacrifice feature against a target that can't see you, you don't take Radiant damage from using the feature and the target is magically silenced on a hit. Until the start of your next turn, the target can't speak, has the Deafened condition, and can't cast any spell that includes a Verbal component.
