You chant a few magical verses and vividly describe a being within your sight range as you hold the straw doll and cloth. Once the cast is over, their features are then cast upon the straw doll with the cloth.
They must make a DC 15 Wisdom saving throw + your spellcasting modifier. If they succeed, they are instantly aware of your presence and pointed to it. If they fail, they don't notice you.
You can use their voodoo doll as you wish, like you would a regular voodoo doll. Any magic and enchantment effects cast on the voodoo dolls are also transferred to the real-life counterpart of that voodoo doll.
Dispelling the Magic
If the real individual holds their voodoo doll or they are a target of a remove curse spell (or something similar), the magic goes malignant and the voodoo doll turns to ash.
