Cursed doll

Over the casting time of the spell you slowly create a small magical doll in the likeness of the target (the target is whose ever blood is used as a material component for the spell also that target does not have to be within range only the blood and string). After you create the doll whoever blood is used as a material component becomes the bonded creature to the doll. After the is created whoever is bonded to the doll it's a wisdom saving throw on a failure they are not aware of the dolls existence, on a success the target is aware of the doll if seceded by 5 or more they can make another wisdom saving throw to make the doll become non-magical and not bonded to them anymore. Whoever is bonded to the doll and on the same plane of existence as it they gain the following effects: 

• The doll has the same amount of hit points and armour class as the bonded preacher. His damage could only be recovered during a long rest.
• If any damage harms the doll the body creature is also harmed taking the same amount of damage and vice versa (note any damage done to someone by the doll does not count as eligible damage for the other one to take damage).
• It's a bonny beautiful creature if an opponent creature if the bonded creature is on the same plane of existence and aware of the doll the bonded creature can use its action see through the dog eyes and hear through the dolls ears using your senses.
• If the bonded creature dies it's all transfers into the doll and it becomes it using it's the creatures game statistics but the creatures strength, dexterity and Constitution become 3 and your size becomes tiny. 120 days after someone soul is transferred into the doll they become their normal self.

I the doll has any exact appearance to the body creature but is made of string or yarn and is the sign of the body creatures hand. If the bonded creature gain any new equipment the doll gain the equipment to this also works if the body creature loses any equipment. If the doll is dispelled or put into a anti magical field it all becomes non-magical using all of its properties but still physically exist.
