Welcome to Gaia! ::

Name: Seijō Gigai
Creator: Unknown.
Users: For now, only the Gotei 13 has the knowledge to create these, but these Gigai can be used by all spiritual beings.
Description: Looks identical to a normal Gigai and is stored the same way.
Use: What differentiates a Seijō Gigai from a normal Gigai is its ability to completely seal and lock the spiritual powers of the spirit it is host of. Not only does it prevent them from using any spiritual ability, it also prevents them from sensing any spiritual activity. Their capacity to see spiritual phenomenon is also greatly diminished, limiting it to a range of 50 meters.
Other: Initially created for infiltration purposes when Shinigami needed to fool the Quincies. It has only recently been unearthed from an old storage room. Ideal for containing inner hollows. Their presence isn't completely erased from an individual's mind, but they cannot affect them physically while a spirit is in a Seijō Gigai.



Name: The Cuna
Creator: Arturo Plateado
Users: Las Noches, only Arturo Plateado may rebuild a Cuna from scratch. Las Noches is capable of mending most damage and reproducing as many Anchors as they wish.
Description: Deep within the bowels of Las Noches is a great hall equipped with a circular platform on which rested a sphere of glowing Reiryoku and Reishi particles. It is held afloat by a powerful cylinder of Reiryoku constantly swirling around it, making even stepping onto the platform a chore for the weaker Hollow. The Cuna cannot function alone, however, and are paired up with Anchors, long, 10-feet tall poles that are quite light and frail for their size.
Use: Though its initial purpose had been to unlock the potential of Hollows, its creator had outdone himself when creating the Cuna. This device has the ability to break down the matter that have been targeted by its anchors into particles and draw them towards itself no matter the distance. Even Kishi, material particles of the Human Realm, will not be spared: the Anchors are equipped with a form of Reishi Henkan-Ki, a device that converts Kishi into Reishi. These Anchors are also capable of replicating a Hollow's ability to create Kumon, allowing them to form tiny portals to send the converted Reishi back to Hueco Mundo. There, acting like a magnet, the Cuna will draw them all towards itself to create a pool of Reiryoku with just the right balance of Shinigami, Hollow and Human essence to create Arrancars.
Other: Needs a certain quantity of Hueco Mundo, Human World and Soul Society particles to be able to fully create Arrancars. This is a plot device and will only be used every now and then.

Name: Hueso
Creator: All Hollows may produce one: it is their mask.
Users: Any
Description: Huesos are Hollow masks. Due to their bone-like property, it is extremely resistant and even more so due to the lingering Reiatsu infused in it originating from the previous owner of the mask before it was ripped off its face.
Use: It is used as a durable material that can surpass steel in hardness depending on its quality and the power of the Hollow it had belonged to. Arrancar ones are extremely precious due to how rare they are and how resistant they are.
Other:

Name: Cuarzo
Creator: Unknown
Users:Any. Only present in Hueco Mundo
Description: As its name suggests, it looks like quartz except that it may take on a variety of colors depending on its purity and the presence of Reiryoku stored within it. It appears to be a natural phenomenon and takes the shape of trees in Hueco Mundo. They are an important component of the Forest of Menos. Cuarzo is most pure below the Forest of Menos as roots of the Menos Forest's trees.
Use: Reiryoku conduct and amplifier. Extremely pure ones are capable of storing Reiryoku and even capable of releasing them in the form of Reiatsu in the same pattern Reiryoku had been stored into it once a small amount of Reiryoku has been injected into it as stimuli.
Other:

Name: Cuarzo Escritura
Creator: Cillian
Users: Las Noches and its affiliates. Anyone may learn it, however.
Description: N/A - Skill/Knowledge
Use: Using the Cuarzo's ability to emit Reiatsu in the same pattern Reiryoku had been stored within it, a way new form of writing was invented. It is like Braille, but instead of feeling with one's fingers, the reader reads with their ability to sense Reiatsu.
Other:

Name: Pw-54 Panzerweste (armor vest)
Creator: Silbern Institute R&D
Users: Issued to members of Blackwolf Security Solutions in the field, but available to veterans and experienced soldat.
Description: The Pw-54 is based on the MOLLE plate carrier used by the US armed forces. It is available in a variety of camouflage schemes.
Use: Designed to give some form of supernatural protection to Quincy operating in the human world It is strong enough to resist most types of bullets and weaponry. The protection comes from impregnating the armor with Soul Made Silver instead of Kevlar. It is also rated against Bala and most unreleased Zanpakuto strikes. The attack might not pierce the armor, but a strong enough strike can still carry enough blunt force to injure. Hits have been known to break ribs and bruise organs even though they haven’t penetrated.
Other:

Name: L-5 Leichentuch (death shroud)
Creator: Silbern Institude R&D
Users: Capable of being used by anyone, the L-5 is usually issued to Wandenreich scouts, spotters and snipers working in the field.
Description: Resembling a ghillie suit, the base L-5 is a khaki burlap cloak and hood. It can be customized with local foliage and cloth to better match the environment.
Use: The suit is made with an alloy of Soul Made Silver and the metal used for Seele Schneider. It conceals the wearer’s reiatsu signature better than Soul Made Silver on its own. The cloak draws spirit particles from the surrounding area to help the user blend into the background. The downside is that the suit offers no protection from physical attacks. It also does not breathe very well, extended operations in hot weather or constant movement will sap the strength of even the strongest veterans.

Name: Bitter Pille (bitter pill)
Creator: Silbern Institute R&D
Users: It is normally issued to sensitive personnel who must avoid capture at all costs. However, it can be used by anyone with rudimentary spiritual control.
Description: A black device approximately the size and shape of a golf ball with two ring pins on opposite sides. It is generally hidden somewhere within easy reach of the user.
Use: Contrary to its name, it is not meant to be ingested. In order to activate it, the user simply pulls on the two safety pins and channels a small amount of spirit energy into it. Once activated, it detonates in an explosion capable of utterly destroying the souls of most Soldat and fatally wounding lower ranking Sternritter/Jagdarmee within the blast radius (approx. 1 meter). The explosion also activates a potent Hollow Bait in order to deter those who would linger in the area.
Other: Due to the method in which it is activated and its small blast radius, the device is impractical as an offensive weapon.

Approved

Added that they can't use the kidō and hoho at the same time

Name: Geist Metall AKA Seele Schneider Metal (SSM)
Creator: Quincy
Users: Quincy
Description: SSM is a lightweight, relatively durable metal with the density of aluminum and the tensile strength of kevlar.
Use: SSM, as the name implies is known mostly for being the primary component of the Seele Schneider. When properly made, it has the ability to absorb spirit energy from the surrounding area and enemy attacks. It is also able to conduct this energy in much the same way as electricity.

Name: Variable Array Long Range Spirit Sensing System (colloquially known as Valrass, or Val)
Creator: Sillbern Institute R&D
Users: Wandenreich, Commonly seen at Blackwolf Installations
Description: The system consists of a latticed tower made from modular sections of aluminum. The sections making up the legs contain a thin wire made from SSM. At the top of the tower is a sphere of SSM about the size of a cantalope that acts as a focus for the device. The most commonly seen variant is approximately 30 meters tall, but can be as tall as 100. The towers are rarely seen alone, often two or three will be constructed relatively close together. The wire is fed into a computer system which can display the signals it receives in an overlay of the area.
Use: The Val senses spirit energy from great distances. The 30 meter variant has a range of approximately 10 kilometers. The massive 100 meter arrays can cover a distance of 50 km.
The number of towers determines the accuracy of the readings. One tower can detect presences to within 100 meters, with two towers, 50 meters, and three towers to within 10 meters. Additional towers can be added for more precision, but three is the most commonly seen amount.
In areas of highly concentrated spiritual presence like Karakura, Soul Society, and Hueco Mundo the background energy creates a great deal of "Noise". In order to counteract this, the device's sensitivity must be reduced, meaning that individuals who can reduce their spiritual pressure could (in theory) slip in "under the radar".
