Cursed Needle

What was once a mighty werewolf was now simply a doll in her hand, black button eyes staring up unblinking. 

You animate a silver needle and thread, sending it towards a target. Make a ranged spell attack, and on a hit, deal 1d4 piercing damage. The target must make a Charisma saving throw, or the needle sews into their skin, leaving a stitch and dealing 2d4 curse points. Curse damage is accumulative, not taking from the targets Hp pool, but is kept track of separately.

These curse points can be removed with a Lesser Restoration.

If the number of curse points exceed their current Hitpoints, the target is transformed into a small stuffed doll bearing resemblance to who they once were. Upon succumbing, they must make one last Charisma Saving throw.

Upon failure, they will lose all signs of life and be rendered an inanimate doll.
On a success, they will continue to be capable of movement and speech, but be transformed into an Animated Doll.
