Dread Word

You speak a dreadful word so foul that it tears at the soul of anyone who hears it. One creature you choose within range that hears you must make a Wisdom save. On a failure, the creature's stunned until the end of its next turn, and its Charisma score becomes 1 for the duration. At the end of each of its turns, a creature repeats the save, restoring its Charisma score to normal on a success.

If a creature fails all saves for the entire 1 minute of the spell's duration, it dies.
