As an action while in possession of a formula scroll, you may use this jutsu, storing an amount of objects you are touching that are not in possession of another creature inside a formula scroll depending on the size. Scrolls, Handy haversacks, and bags of holding cannot be stored within scrolls, if attempted, the attempt fails and the scroll, and any of its contents, are destroyed. Objects within a scroll are sent to their own dimension exactly as large as the scroll's maximum capacity.

Formula scrolls, and any modified versions of them, count as magical items for the sake of being destroyed.

If this seal is destroyed by any means, such as from this jutsu ending, the Unsealing Technique, or by removing the limb bearing the seal, the genjutsu this jutsu was effecting ends as well.

Jinchuriki Seal

Cost: 20 chakra

Range: 15 ft.

To use this jutsu, you must first write a seal on a humanoid using ink as an action. This seal lasts for 12 days or until it is removed as an action.

On a success, you gain one level of exhaustion and the creature is sealed inside the humanoid, who becomes unconscious for 1d10 hours. After a creature has been sealed, the only way to remove the seal is with this Jutsu to target one creature sealed within them, and the target may cause this jutsu to fail by succeeding a Dexterity saving throw against your jutsu save DC. If the creature is a Tailed Beast, the humanoid becomes a jinchuriki. If the creature is not a Tailed Beast, the humanoid becomes a vessel.
