"Present day Bazz has demonstrated the ability to use the abilities of The Heat up to and including Burner Finger 3, and he's obviously still in possession of his Heilig Bogen abilities, so what exactly did Yhwach steal with Auswählen?"

In the issue before last, IIRC, Bazz said that Auswahlen took away their Quincy Vollstandig powers. So the surviving Sternritters retain their basic Quincy powers and the Shrift abilities they have outside of Vollstandig.
