Servant of the Doll

The servent of the doll warlock specializes in battlefield control and illusions, choosing to either have their enemies fear them or stopping them from dealing substantial amounts of damage.

Astral Replacement

When you hit 0 hp your soul is transferred to the doll of your patron. While in this form your ac, hp, and speed are halved (not accounting for your feats).  For the transfer to happen the body and doll must be within 10 ft of each other and while in doll form you can't use weapons and can only use cantrips.

Can't be touched

At level 10 while in combat, you can freely cast mirror image twice per long rest.

Master illusionst

At 14th level, you have advantage on checks and saves against illusion magic and will instinctively know if a spell of that school of magic has been cast.

Copy cat

You can cast a spell that you have seen in the last hour as long as it doesn't require material components and you have both heard the name of the spell and seen the semantics.

Dolly's Youth

You no longer adhere to the laws of aging and can't be aged magically.

Cute as a button

You gain proficiency in either persuasion or deception.
