changeling

Changelings can shift their forms with a thought. Many changelings use this gift as a form of artistic and emotional expression. It's also an invaluable tool for grifters, spies, and others who wish to deceive. This leads many people to treat changelings with suspicion. Changelings are commonly harmless, passive people and are uninterested in politics and social affairs. Due to their capricious ways of life, however, many people have come to distrust changelings, which has led to them becoming social recluses or more commonly has pushed them to create fake identities to escape persecution.
Having no culture of their own, changelings slip into other's societies and blend in. Rather than creating their own art and achievements, changelings are happy with claiming other societies' as their own. This nomadic lifestyle has led changelings to become exceptionally adaptable people. Changelings will not simply shapeshift into a new person but rather create a new whole one. Most changelings will set up a handful of personas so if one is compromised they can disappear and switch to one of their others. Their personas are incredibly realistic and have their own personality traits, backgrounds, and a network of friends. Changelings can be evasive and will often try to avoid confrontation or anything that will draw attention to themselves.

True Form

While changelings can look like anyone, they do have a true form. Their natural look can be scary to some due to their lack of detail and distinctive features. Their skin tone is always pale, either white or light gray, and they tend to have slender bodies with limbs slightly longer in proportion to other humanoids. They have large colorless eyes circled by thick black rings. Their hair color is most commonly a light shade of silver followed by platinum and blonde. In rarer cases, their hair can be pale shades of green, pink, and blue. Similar to elves, changelings lack body and facial hair. However, most changelings are rarely seen in their true form and prefer to adopt all kinds of humanoid shapes, treating their appearance like others treat clothes. This includes gender.

Size In their natural forms, changelings average between 5 and 6 feet in height, with a slender build. Your size is Medium.

Speed Your base walking speed is 30 feet.
Change Appearance 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, though 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.
Unsettling Visage When a creature you can see makes an attack roll against you, you can use your reaction to impose disadvantage on the roll. You must use this feature before knowing whether the attack hits or misses. Using this trait reveals your shapeshifting nature to any creature within 30 feet that can see you. Once you use this trait, you can’t use it again until you finish a short or long rest.
Divergent Persona You gain proficiency with one tool of your choice. Define a unique identity associated with that proficiency; establish the name, race, gender, age, and other details. While you are in the form of this persona, the related proficiency bonus is doubled for any ability check you make that uses that proficiency.
Languages You can speak, read, and write Common and two other languages of your choice.
