If you do so, you have advantage on the next Charisma (Persuasion) check you make against a humanoid while you are in an area containing 12 or more humanoids. In addition, while wearing the scarf, you can use modify memory on a humanoid you have successfully persuaded in the last 24 hours. The scarf can't be used this way again until the next dawn.
