Quincy: Vollständig

is a part of Quincy evolution and the answer to the drawbacks of the outdated Quincy: Letzt Stil.

Overview
Quincy: Vollständig is nothing like Quincy: Letzt Stil. The Wandenreich view Quincy: Letzt Stil as a "relic of the past" because its very notion died out around 200 years ago due to its fragility. Quilge Opie notes the only one who displayed a tenacity toward the ability was Sōken Ishida, the man who denied the Quincy's evolution and studies. Thus, Quincy: Letzt Stil is an obsolete technique.

In order to activate Quincy: Vollständig, a Quincy must remove their Sanrei Glove, but there are exceptions, such as Mask De Masculine, who uses a Sanrei Belt, and Äs Nödt, who can activate it by rolling back his left eye, revealing a Wandenreich emblem on the inside of his eyeball. However, a Quincy is unable to use Quincy: Vollständig while in possession of a Shinigami's Bankai.

Features
Quincy: Vollständig takes on a variety of forms, but most commonly gives its user an angel-like appearance with wing-like Reishi constructs and a star-like halo. Those whose Quincy: Vollständig give them these visual traits include Quilge Opie, Bambietta Basterbine, Candice Catnipp, and the Unnamed Male Sternritter. However, not all Quincy: Vollständig grant these specific constructs: Mask De Masculine's Quincy: Vollständig gives him a cape-like Reishi construct on his back, small wings on his neck, and a giant star on his head, and Äs Nödt's Tatarforas gives him ring-like spikes on his back and a spiky halo on his head.

General Abilities
Complete Reishi Dominance: Quincy: Vollständig allows the user to absorb a large amount of Reishi at the tip of their spirit weapon to use in a powerful attack. In this form, a Quincy's capability for Reishi absorption increases drastically. They can absorb the trees, sand, rocks, and even the buildings in Hueco Mundo or Soul Society, as well as Orihime Inoue's Santen Kesshun and spiritual lifeforms such as Ayon.


 * Flight: Quincy: Vollständig users can use the Reishi wings generated by the technique for high-speed flight.


 * A Quincy can use the most basic ability to gather Reishi in the most powerful way; by enslaving it. It literally tears away the components which make up Reishi-based objects, such as those which make up Hueco Mundo and Soul Society, as well as the bodies of spiritual beings, such as Ayon. When the body of a spiritual being is affected by this power, a Quincy can assume the characteristics and associated capabilities of his victim. However, the transformation is not permanent, for the power absorbed eventually vanishes.


 * Spirit Weapon: With their Quincy: Vollständig activated, a Quincy can produce a Spirit Weapon, made entirely of Reishi, from the gauntlet on their wrist. They can use this weapon for both melee attacks and to fire Heilig Pfeil.


 * Enhanced Schrift: The ability granted by a Sternritter's Schrift is is greatly amplified. Its power and range are raised, and a Quincy gains access to new techniques which they can't use normally.


 * Enhanced Spiritual Awareness: A Quincy using Quincy: Vollständig can sense Reiatsu to a far greater level, allowing them to surpass any ability which would hide one's presence if they are more powerful than the opponent in question.

Trivia

 * This ability is called Quincy Vollsterndich in the English localization of the manga.
