Cute as a Button

At 1st level you gain the ability to cast the cantrip Friends, this does not count towards your overall known cantrips.  You may also use this cantrip on any humanoid doll like figure, such as toys or mannequins, bringing it to life for one minute.  During the time that the figure is alive you may ask it five questions about something it has seen or heard in an area someone has placed it.  The answers can be vague, cryptic or outright truthful all depending on the dolls personality. You may only use the cantrip in this way once per short or long rest.

Inhuman Movement

At 6th level you can use your inhuman control over your movement to avoid an incoming attack.  After seeing an attack made against you, you may roll a D10 and add your Charisma modifier to reduce the attack roll by that number.  You may not use this feature again until you finish a short or long rest. Along with this due to your doll-like stillness, you have an advantage on all Dexterity (Stealth) checks while you are completely still.

Ain't No Strings on Me

At 10th level, as an action you may target one creature of sizes Large or smaller and lash out at them with the newly found puppet wires within your body.  You may cause the target 3D8 + Charisma modifier necrotic damage, gaining hit points equal to the total amount of the necrotic damage. Along with this, the target must make a Dexterity saving throw against your Spell Save DC, on a failure the target is grappled until the end of your next turn.  On a success the target takes half of the necrotic damages that would be given. Fiends (Devils) have disadvantage on this saving throw. This ability can not be used again until you finish a short or long rest.

All Dolled Up

At 14th level you are able to show your true form for a short time.  As an action you bring forth a tide of dolls such as yourself from the abyss in a 60ft radius around you until the end of your next turn.  Any enemy creature that starts there turn within this radius must succeed a Wisdom Saving Throw against your Spell Save DC. On a failure they are Frightened of you and take 3D10 necrotic damage, along with another 3D10 necrotic damage if they end their turn inside the radius.  On a success they are not Frightened and take half of the damage they would have received on a failure. Fiends (Devils) have disadvantage on this saving throw. This ability can not be used against until you finish a long rest. 

Along with this, at 14th level every 10 years lived equals 1 year lived for you.  This can be extended even further by replacing your own body parts with a doll like equivalent.
