All Quincies have the ability to create a unique spirit bow, and subsequently generate spirit arrows for the bow, using a Quincy cross or pentacle. The bow and arrows are both made up completely of reiryoku from the users surroundings, and last as long as the wielder's stamina and reiryoku reserves allow.
Reiryoku Absorption: Unlike Shinigami, who use their inner Reiryoku to fight, the Quincy fuel their abilities by absorbing the Reiryoku of their surroundings in the form of spirit particles. They primarily absorb them from the atmosphere, and have an easier time collecting this energy in environments with higher concentrations of spiritual particles, such as Soul Society or Hueco Mundo. To a sufficiently powerful Quincy, there is no difference between spiritual particles and spiritual energy as a source of power.
Reiryoku Manipulation: one can manipulate spiritual energy for offensive purposes. They most commonly reshapes spiritual particles into various types of bow and arrows, but can also concentrate spiritual energy into the form of swords or explosives.
Quincy Combat
The Quincy can also use the energy they gather, or use silver tubes filled with spiritual energy (see below), to perform various offensive, supportive, and defensive techniques similar to the Shinigami Kidō.
A Quincy's power can be significantly enhanced using the Sanrei glove. A Quincy needs to complete a week of intense training in order to be able to use the glove. The glove operates by repelling spirit particles, making it far more difficult for the Quincy to summon their bow. Any Quincy who is able to successfully utilize their powers while wearing the glove can thus reach much higher levels of power. This training is also the basis for the Quincy final form.
A Quincy who wears the Sanrei glove may remove it in desperate cases, entering a state known as the:
Quincy Final Form: The Quincy Final Form gives the user a tremendous amount of power, but at the price of their powers upon it's completion. See main article for more information.
The only way for a Quincy to regain their powers after using the final form is to first exhaust themselves both mentally and physically, then be hit exactly 19 mm to the right of their heart with a spirit arrow. After this, a pentacle-shaped scar will form on the point of impact, and their powers will be restored.
Quincy items
The Quincy possess numerous artifacts and equipment which help them in different ways. Below are the ones that have been shown:
Hollow bait — This item is a small, coin-shaped disk that attracts hollows when crushed. When used by Uryū, the bait, in combination with Ichigo's powerful spiritual pressure, was able to draw a Gillian-class Menos out of Hueco Mundo.
Quincy bangle : Introduced in the anime's Bount arc, the Quincy Bangle is an artifact designed to mimic a Quincy's natural powers. It works by drawing in spirit particles from the environment, much like a Quincy does regularly. It can only be used properly by those who are already adept at forming and directing spirit particles.
Quincy cross— Standard equipment for any Quincy, the Quincy Cross acts as the focus for a Quincy bow. The cross need not necessarily be in a cross shape, as Ryūken's cross is a pentacle.
Sanrei Glove: The sanrei glove is a powerful Quincy artifact that can increase a Quincy's power exponentially, but requires a dangerous and exhausting type of resistance training (wearing it for a week while constantly firing spiritual arrows) to master. The glove works by scattering the spirit particles in the surrounding area, making it much harder to form a working bow. If a Quincy can summon a bow and use it for the required amount of time, they will have undergone a massive increase in power. When removed, however, the glove will release the user's energy all at once - first transforming them into a being of tremendous strength, the Quincy Final Form, and then forcing their Quincy powers to gutter out completely.
Seele Schneider: The Seele Schneider is a thin sword that can be fired similarly to an arrow. It's much longer than a standard arrow and functions something like a chainsaw: the spirit particles of its blade vibrate at ultra-high frequencies, loosening the molecular bonds between any spirit matter it cuts so that the Quincy user may easily absorb the freed spirit particles. Uryū also stated that using it increased his spiritual power. The Seele Schneiders Uryū uses are stolen from a secret storage room under Karakura hospital.
Silver tubes: Silver tubes are small liquid-filled capsules that store spiritual energy, and are used by Quincy for spellcasting in the same way that Shinigami use kidō. Like kidō, they are activated by calling out various commands.
Soul-synthesized silver— Soul-synthesized silver was used by Ryūken Ishida to construct the hidden chamber in which Uryū trains.
Soul-synthesized glass — Like soul-synthesized silver, soul-synthesized glass was used to construct the hidden chamber in the Karakura Hospital.
Quincy Techniques
To go with their bow, the Quincy have a number of special techniques to give them an edge in combat:
Hirenkyaku: Analogous to the Shinigami Flash Steps or the Arrancar Sonído, the Quincy Hirenkyaku allows the user to move quickly over short distances; according to Uryū Ishida it is faster than flash steps, though Mayuri Kurotsuchi's superior speed suggests that this is just a generalization. To perform the technique, the user gathers spiritual particles under their feet and rides them to the desired location. Like the air-walking skill displayed by most Arrancar and Shinigami, it can also be used to hover or fly for long distances. Mayuri compliments Uryū on being able to use this technique at such a young age, suggesting that it is difficult to master.
Ransōtengai— this is a high level technique that allows the user to control their body parts using strings of spirit energy controlled by their brain, forming lines or strings out of countless spiritrons. By using this technique, the user can control their body as one would a puppet, allowing them to move freely despite paralysis, broken limbs, or any other force that would impede normal movement. It was originally created to allow elderly Quincy to fight effectively, and is rare enough that Mayuri had never encountered a Quincy (out of the 2661 that he examined or studied) who could use it before Uryū.
Dislocated joints and broken bones are meaningless against this technique. Mayuri stated it as "the most powerful technique for the Quincy," but he did not know of the Quincy Final Form, which means as far as Mayuri knew it was the strongest.
