Crimson Ribbon

A long beautiful blood red ribbon coils around the mouth of a creature you can see within 30 feet. The creature must make a Wisdom saving throw. On a failed save, the creature takes 5d8 psychic damage and the ribbon remains around their mouth, preventing them from being able to speak or make any audible sound for the duration of the spell. On a success, they take half damage and the ribbon rips and tears off them. 

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the number of targets increases by 1 for each slot level above 3rd.
