Vanilla Fuinjutsu

Name: Generic Sealing/Unsealing Technique
  Rank: D/E
  Type: Fuuinjutsu
  Used For: Supplementary
  Element: -
  Range: Contact
  Duration: -
  Hand Seals/Charge up: Seal Mark must be inscribed or carried ahead of time.
  Description: With this technique the user is able to store a variety objects or jutsu within a scroll or other surfaces with the seal inscribed, depending on the user's skill with Fuuinjutsu. While sealing an object takes a considerable amount of concentration for those unskilled with Fuuinjutsu, unsealing an object is simple enough and can be performed on the fly so long as the symbol is accessible to the user and thus making it possible to unseal a weapon in the midst of battle. Sealing in battle, however, is not possible for those who are unskilled in Fuuinjutsu.
  Weakness: Seal Marking must be drawn or prepared ahead of time.

Element: N/A
Range: Contact
Duration: Permanenet
Hand Seals/Charge up: None
Description: The user concentrates chakra into their finger and using the heat from that, can apply writing of whatever they want to a surface. This technique however requires them to be very delicate with their chakra control.

Name: Cloth Binding Technique
Rank: B
Type: Fuuinjutsu
Used For: Sealing
Element: N/A
Range: -
Duration: Permanent until seal is released
Hand Seals/Charge up: Tiger, Sealing tag has to be on cloth in the first place
Description: The user uses a giant roll of cloth to tightly wrap up the intended opponent, completely immobilising them, thus preventing them from moving or using any techniques. The ability itself is versatile as once completed, the addition of further seals can be placed on top of the bound victims, preventing them from even being summoned while in effect. This technique is used by Sunagakure ninja.
Weakness: Mere physical contact with the cloth seems to be required to use this technique. Can only be used by Fuuinjutsu Adepts or higher. Jutsu is primarily for Edos, so if used on a living being one has to pay chakra costs up to the next turn or else the seal will unravel. Edos are sealed the moment it's placed on them, though.


Name: Fire Sealing Method
Rank: B
Type: Fuuinjutsu
Used For: Sealing
Element: N/A
Range: 5 meters
Duration: Permanent
Hand Seals/Charge up: Rat → Bird → Technique specific seal → Tiger
Description: A kind of fūinjutsu that involves sealing a technique's effects within a specific location. As it is tailored for fire release ninjutsu, it requires a caster well-versed in the exacting art of "Sealing Formulas", as well as in ninjutsu. The jutsu-sealing space in the scroll is left blank, for the formula to be inscribed in with a brush. After performing the needed hand seals, chakra-like vapour appears from the scroll, and envelops the flames. They are sucked in towards the scroll, and the appearance of the kanji for seal (封) certifies the technique's completion. Once the sealing is performed, the technique's effects cannot be released anew as long as an unsealing technique is not applied. It is an effective technique to circumvent any secondary damage a dangerous enemy technique might cause. It is even capable of sealing the black flames of Amaterasu [can seal Katon up to B-rank, Katon up to S-rank can only be sealed if they're not used offensively. Meaning the flames can still be left out to be burnt but is not used to attack you. Sealing A-rank+ Katon still requires the necessary chakra payments.]
Weakness: Requires Ninjutsu and Fuuinjutsu Adept. Can only seal one Katon within a close area at a time.


Name: Sealed Iron Wall
Rank: B
Type: Fuuinjutsu
Used For: Sealing
Element: None
Range: -
Duration: Permanent
Hand Seals/Charge up: Snake, Rat, Tiger.
Description: A seal placed on the Fire Temple's gate, in order to defend against intruders from the outside world. The two statues placed on either side of the gate form a barrier. The seal can only be cancelled by pouring in the Gift of the Hermit Group, special chakra peculiar to the ninja monks of the Fire Temple. The user can manipulate it so that only particular chakras can open the gate.

However, as shown when Kakuzu used his Earth Release: Earth Spear to strike the gate, a powerful enough physical attack can destroy the seal [You'd need at least a B-rank attack to knock this down].
Weakness: Has very little combat applications.

Name: Five Elements Seal/Unseal
Rank: A
Type: Fuinjutsu
Used For: Offensive
Element: N/A
Range: Contact
Duration: Permanent until removed; however, the user still has to pay lasting chakra for the next three turns until it is permanent.
Hand Seals/Charge up: Technique specific seal
Description: Five Elements Seal is a technique which produces a powerful seal that is used to block or disturb the target's chakra flow.
Once the seal is completed, the target will become unconscious and unable to fight for a short time. Orochimaru performed this technique to tamper with Naruto Uzumaki's seal. The original seal allowed a small amount of the Nine-Tails' chakra to always mix into Naruto's, but the additional seal disturbs this, preventing Naruto from using the Nine-Tails' chakra or even controlling his own chakra properly. This is because an odd-numbered seal creates an imbalance when placed on top of an even-numbered seal. When Orochimaru later notices that the seal has been removed, he remarks that there are very few ninja capable of doing so, like Jiraiya.

Five Elements Unseal is a direct counterpart technique of Five Elements Seal. This technique can be used to remove fūinjutsu of up to equal power, like its counterpart.
Weakness: You need Fuuinjutsu Mastery for this. See Duration condition.

Name: Iron Armour Seal
Rank: A
Type: Fuuinjutsu
Used For: Sealing
Element: No
Range: -
Duration: Permanent until removed/broken
Hand Seals/Charge up: Tiger, Rat, Dragon, Monkey, Rat, Tiger, Bird, Rabbit, Snake.
Description: Iron Armour Seal was the fūinjutsu used by Kumogakure to seal Gyūki into its respective hosts.
The seal itself takes the form of the kanji for "iron" (鉄, tetsu) and is usually printed somewhere on the jinchūriki's body: Killer B's right shoulder, and Fukai's chest. Not much else is known about the seal, besides the fact that it was stated by B to be of lower-quality and weaker than the Four Symbols Seal, which was used to seal Kurama inside of Naruto Uzumaki.
Weakness: Seal is more easily to broke than high-quality S-class seals such as the Four Symbols seal. The manipulation of it is much more limited compared to the Four Symbols.


Name: Evil Sealing Method
Rank: A
Type: Fuuinjutsu
Used For: Sealing
Element: N/A
Range: -
Duration: Permanent until removed
Hand Seals/Charge up: Preparation for this technique requires two concentric circles with kunai placed in intervals along the circumference, in addition to a number of characters written in blood that radiate out from the centre of the cursed seal.
Hand Seals: Hare → Snake → Horse → Ram → Bird → Tiger → Hare → Snake → Horse → Ram → Bird → Tiger → Hare → Snake → Horse → Ram → Bird → Dog → Rat
Description: This technique is used to suppress technique-induced marks on a person. Marks of weaker power can be completely suppressed by this technique alone, but for marks of higher power, like Sasuke Uchiha's Cursed Seal of Heaven, it will cause the seal's power to become dependent on the recipient's own willpower to some extent, especially if the sealer is not experienced enough to strengthen the seal with his own power. It is also capable of holding back certain kekkei genkai, such as that of the Kurama clan as seen when Kurenai tried to do this.

According to Kakashi, this technique is quick, but painful. The seal can be removed at any time by the caster or whoever the seal is on, as demonstrated during Sasuke's battle with Naruto in the Valley of the End. Since this seal relies on the will of the individual on whom it is placed, the affected may be able to will it away without an unsealing technique.


Name: Evil Releasing Method
Rank: A
Type: Fuuinjutsu
Used For: Releasing seals
Element: N/A
Range: -
Duration: Permanent
Hand Seals/Charge up: Tiger → Snake → Horse → Ram → Tiger → Hare → Rat
Description: The Evil Releasing Method is a direct counterpart to the Evil Sealing Method, this technique is used to release technique-induced seals [up to S-rank] on a person rather than sealing it. Compared to the Evil Sealing Method, the Evil Releasing Method requires far less preparation.  

Name: Sealing Technique: Lion Closing Roar
Rank: A
Type: Fuuinjutsu
Used For: Sealing
Element: None
Range: Close+
Duration: Permanent if target is hit
Hand Seals/Charge up: N/A
Description: This sealing technique completely blocks the target's chakra with a sealing formula (封印式, fūin-shiki) drawn on the ground or a wall. This is done by closing all the tenketsu of the person caught in the middle. When the target is sealed, a stylised kanji for "close" or "shut" (閉, hei) appears in the middle of the sealing formula.

Weakness: To successfully seal the target, one has to get them exactly inside the sealing formula (right in the middle). This requires great accuracy and is very difficult. Various methods can be used to make this easier. For instance, one can prepare a puppet or a ninja tool like the Lion-Headed Kannon with this sealing formula.



Name: Transcription Seal
Rank: A
Type: Fuuinjutsu
Used For: Supplementary
Element: -
Range: -
Duration: Until the jutsu sealed is released.
Hand Seals/Charge up: Hand seals for the jutsu have to be executed, and chakra has to be transferred.
Description: This is a technique that seals certain jutsu within certain points on a target, whether it be an eye or particular mark/seal. it is involuntarily activated when certain requirements are met, which are determined by the user. This technique is used by Itachi to seal Amaterasu in Sasuke's Sharingan, only to activate upon seeing a particular thing. Madara Uchiha also used this to seal the Izanagi in his Sharingan to have it trigger after his death.
Note: If you intend to use this, check with admins to determine what you're sealing and where you're sealing it into beforehand, as this is a purely case-by-case basis jutsu.

Hand Seals/Charge up: 5 hand seals
Description:The Four symbol seal can seal any target into a human or object.  In order seal larger targets or more powerful ones such as tailed beast Eight trigrams must used, which is two four symbols.  Anyone who has the four symbols will be able to use Eight, if they are a Master sealer and an Uzumaki or have learned from one.  This will cost an S rank amount of chakra plus the continuation chakra for S rank jutsu. The sealing process first begins by summoning a ceremonial alter.
When the jutsu is activated by placing the seal on the a surface: The target to seal will become an intangible mass of chakra that will be sucked into the seal.  If the seal is placed on something with the capacity think such as person then they can interact with whatever is sealed inside them.  Although whatever was sealed will be restricted by whatever medium their subconscious comes up with (Chains, cage, ect).  A skilled Fuinjutsu practitioner can place the seal so that what is sealed can leak out or completely shut it away.  Whatever is sealed can be viewed in a inner subconscious world accessible to the person with the seal and those with special jutsu, such as a three tomed sharingan user.  A skilled Fuinjutsu user can also place a trap to activate when attempts remove the seal made.
Weakness:If sealed inside a living being they can remove the seal of their own free will.
