You are among the most powerful Quincy created for the subjugation and destruction of Soul Society and the Shinigami who live there.
Your Reishi manipulation and physical capabilities have grown to give most Shinigami trouble, and you are able to match most Captains who have yet to release their Bankai. As a member of the Sternritter, you have access to a Schrift, a sacred letter that denotes a potent ability powered by the blood of Yhwach and inscribed on your soul. While powerful, yours still stands below the Schrift of the Schutzstaffel. However, you do have a unique protection against Ywhach's Auswählen.
As a Sternritter, you are also capable of using Vollständig, a potent evolution of Letzt Stil. It grants you an angelic visage composed of Reishi constructs and grants you additional abilities:
Reishi Dominance: your Reishi manipulation is put into overdrive, allowing you to absorb large amounts of Reishi into the tip of your Spirit Weapon, enabling a powerful attack. In places of notable spiritual composition, such as Hueco Mundo or Soul Society, your Reishi absorption is capable of even absorbing Reishi from the likes of trees, rocks, or even buildings.
Flight: by forming Reishi constructs in the form of wings, you are capable of high-speed flight.
Enhanced Spirit Weapon: your Spirit Weapon can now be formed entirely out of Reishi.
Enhanced Schrift: whichever ability was granted to you through your Schrift enters a greatly amplified state, enabling you greater power and range, and even access to techniques you normally couldn't use.
Enhanced Spirital Awareness: your ability to sense Reiatsu receives a similar enhancement, allowing you to overcome abilities that would otherwise hide someone's presence to you. You also receive the special medallion of the Sternritter allowing you to steal Bankai, and possibly other weapons that are parts of their owner's soul. Any stolen Bankai you use merely grants its form and power, you must still train to master it, and you are unable to use your Vollständig while wielding it.
