Black Tongue

Choose one creature you can hear within range. The target must make a CHA save or be unable to speak deliberate lies, cast powers with verbal components, or command summoned creatures for the duration. It repeats the save at the end of each of its turns, ending the effect on a success.

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