Fuinjutsu

**Fūinjutsu** (封印術, Literally meaning: Sealing Techniques) are a type of jutsu that seal objects, living beings, chakra, along with a wide variety of other things within another object.
The esoteric nature of Fuinjutsu grants it broad capabilities from restricting physical movement to sealing things without physical form such as memories, words or ideas. The presence of a seal is marked by the appearance of formations of technique formulae, kanji, or else other kinds of symbols. In a similar fashion to genjutsu, Fūinjutsu can be undone by combining specific seals with a Fūinjutsu: Release (封印術・解, *Fūinjutsu: Kai*, Literally meaning: *Sealing Technique: Release*) command.

## Roleplay

Fuinjutsu is one of the many specialization fields. A ninja's proficiency in Fuinjutsu is based on their Fuinjutsu specialization stat. The higher the level of the ninja's Fuinjutsu specialization, the more powerful, and broad they are able to apply their craft.

Proficiency in Fuinjutsu grants the wielder a variety of methods for its utilization. First is the creation of sealing array on an object. This is the most basic ability of Fuinjutsu and it allows for the creation of sealing tags, sealing scrolls and Ninjutsu Technique Scrolls. You may craft any jutsu you know into a sealing scrolls or ninjutsu technique scroll without having to pay its chakra cost.

**Cooperative Sealing Jutsu:** Using fuinjutsu its possible to setup a sealing array and with the aid of other ninja's you may cooperatively pool your resources together to perform high-level techniques. When using this method, you must first establish a sealing array. This can either be done by the caster himself or with the aid of other fuinjutsu specialists. In doing so you may add the fuinjutsu specialization of each attending member together. The maximum level can be no greater than twice the level of the highest ranked member.

This method can also be used when where it concerns expending the stamina to perform a technique that is to be sealed by drawing on multiple members. No one member may contribute more chakra than the Fuinjutsu Specialization level of the primary caster. For example if a Fuinjutsu specialist with 100 levels uses this method, they can pool the abilities of other fuinjutsu specialists totaling up to level 200. This method allows one perform higher level sealing, and would potentially allow the caster in this scenario to seal a Jinchuuriki or even an S-Rank technique.

**Sealing Formulae Jutsu:** Are a unique brand of fuinjutsu which go beyond the use of technique scrolls. No longer bound by the cumbersome necessity of fabricating a sealing array on a technique scroll, Fuinjutsu specialists eventually develop short-hand methods to quickly perform their sealing arts. Some create tools, others simply engrave sealing arrays on their body, whatever the method the end result is the same. With this ability you may perform a *Sealing Formulae Jutsu* which allows you to cast sealing arts as you would any ninjutsu. When doing so you must use a surface on which the sealing formulae will imprint on, allowing you to perform any sealing art or jutsu you know. The benefit of this is that like standard sealing arts you can set preconditions or triggers that will release at your discretion.

**Creation and Manipulation of Jinchuuriki Seals:** Your proficiency in fuinjutsu has increased to such an extent that you are able to craft sealing arrays capable of sealing even the most powerful of entities. When applying a sealing jutsu in this fashion you may seal a chakra beast, that is a Tailed Beast into a human creating a Jinchuuriki. Due to your knowledge you may also unseal a Tailed Beast, though to do it safely without the Tailed Beast rampaging about may require further precautions....

With this knowledge you also possess the unique ability to apply additional seals on existing sealing arrays that can either weaken the seal on a Jinchuuriki or reinforce the seal. Using a sealing jutsu to weaken the seal can temporarily grant the Jinchuuriki an increase in strength as they are able to awaken more abilities of the Tailed Beast. Manipulating the seal in this manner allows you to at a cost of 50 stamina temporarily increase the Jinchuuriki Level of a Jinchuuriki host by up to 50% of your Fuinjutsu level. Conversely you can reinforce the seals weakening their connection to their Tailed Beast, adding a debuff by lowering their effective Jinchuuriki level by up to your Fuinjutsu level.

### Progression

* **Level 10:** You gain the ability craft sealing scrolls. Sealing scrolls can store objects of any size limited to what a human could carry.
* **Level 25:** You gain the ability to craft explosive seals and tags, and your ability to seal objects increases to volumes of mass roughly the size of a house.
* **Level 50:** You gain the ability to seal C-Rank Ninjutsu or below into a Ninjutsu Technique Scroll. Using a Ninja Technique Scroll does not expend stamina in this way, but it does require the requisite level of Control to perform the jutsu. You may craft any number of Ninja Technique Scrolls so as long as the total stamina that would have been expended does not exceed your level in the Fuinjutsu Specialization. The Control stat's chakra cost reduction does not apply. Nor do favorable environmental conditions which would reduce chakra costs. You may also seal living beings in objects at this level.
* **Level 75:** You gain the ability to perform Cooperative Sealing Jutsu.
* **Level 100:** You gain the ability to seal B-Rank Ninjutsu into a Ninjutsu Technique Scroll.
* **Level 150:** You gain the ability to seal A-Rank Ninjutsu into a Ninjutsu Technique Scroll. You also gain the ability to perform Sealing Formulae Jutsu.
