Nonchalant

You're good at shrugging off fear and enthrallment, and can convince any casual observer that your composure is unassailable. You gain the following benefits:

• Increase your Charisma score by 1, to a maximum of 20.
• You can add your Charisma modifier to saving throws against being charmed or frightened.
• If a creature forces you to make a saving throw against being charmed or frightened, or is aware that you are making such a saving throw, they will believe that you have succeeded on the saving throw irrespective of its results. A creature who uses their action to observe you can determine whether you are charmed or frightened with a successful Wisdom (Insight) check with a DC equal to your Charisma score.
