Ever-Shifting Body

You have connected with ancient changeling secrets in your blood, gaining knowledge long-forgotten.

• Divergent Persona:  You gain proficiency with one tool of your choice.  Establish a persona related to this proficiency, including a name, race, age, sex, and any other details.  While in this persona, you can double your proficiency bonus on the check.
• Unsettling Visage:  When a creature within 30 feet you can see makes an attack roll against you, you can use your reaction to impose disadvantage on the roll.  Doing so reveals your shapeshifting nature to any creature who can see you within 30 feet as you shift your appearance in a way that is distressing to that creature.  You may do this once per short rest.
