Mute

Choose one creature within range. The target must make a CHA save or become unable to speak, sing, shout, or create intentional vocal sound for the duration. It cannot use powers requiring verbal components, command words, song, or speech. It repeats the save at the end of each turn.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
