Hesper's Hush

Choose a creature you can see within range. That creature must make a Wisdom saving throw or be rendered mute for the duration, unable to speak or create any vocalisations of any kind. The creature cannot cast spells requiring verbal components or use command words to activate magic items. The creature may make another Wisdom saving throw at the end of each of it's turns, ending the spell's effect on that creature on a successful save.

When cast at level 2 or higher, choose up to one additional creature for each spell level above the 1st.
