Because you are a fiend, you have superior vision in dark and dim conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern color in darkness, only shades of gray.

Your creature type is considered to be both Fiend and Humanoid, and you are considered to have the "Shapechanger" tag. Additionally, you are vulnerable to radiant damage.

As an action, you can transform your appearance or revert to your natural form. You can't duplicate the appearance of a creature you've never seen, and you revert to your natural form if you die.

You decide what you look like, including your height, weight, facial features, the sound of your voice, coloration, hair length, sex, and any other distinguishing characteristics. You can make yourself appear as a member of another race; you lose the flying speed granted by your wings trait if your current form does not have wings; otherwise, none of your game statistics change. You also can't appear as a creature of a different size than you, and your basic shape stays the same; if you're bipedal, you can't use this trait to become quadrupedal, for instance. Your clothing and other equipment don't change in appearance, size, or shape to match your new form, requiring you to keep a few extra outfits on hand to make the most compelling disguise possible.

Even to the most astute observers, your ruse is usually indiscernible. If you rouse suspicion, or if a wary creature suspects something is amiss, you have advantage on any Charisma (Deception) check you make to avoid detection of your true nature.

You have proficiency with the Persuasion skill. If you spend 1 minute talking to someone who can understand what you say, you can make a Charisma (Persuasion) check contested by the creature's Wisdom (Insight) check. If you or your companions are fighting the creature, your check automatically fails. If your check succeeds, the target is magically charmed by you as long as it remains within 60 feet of you and for 1 minute thereafter.

You have a pair of wings that give you a flying speed of 30 feet. You cannot use this fly speed if you are wearing medium or heavy armor or if your current form granted by your shapechanger trait does not have wings.

You can read, speak, and write Common and your choice of Abyssal or Infernal.
