Shapeshifter Tiefling
Race Details
Some fiends defy classification and some are expert shapechangers. Such are the succubi and incubi, who inhabit all of the Lower Planes and can be found in service to devils, demons, night hags, rakshasas, and yugoloths. Tieflings with a heritage that is heavily tied to shapechangers such as succubi and incubi can inherit some of their traits.

You can also adjust your height and weight, as long as your size is always Small or Medium. You can make yourself appear as a member of another race, though none of your game statistics change. You can’t duplicate the appearance of a creature you’ve never seen, and you must adopt a form that has the same basic arrangement of limbs that you have. Your clothing and equipment aren’t changed by this trait.
You stay in the new form until you use an action to revert to your true form or until you die.
Shapechanger Instincts
You gain proficiency with two of the following skills of your choice: Deception, Insight, Intimidation, and Persuasion.
