Multiple cruxy bits -- including off the deck, if you take the straightest line! After ~6 bolts, stay to the right and get a good rest standing up on the pillar (left goes a 7b towards the roof of Gummiadler).
Crux is about knowing which of the pockets to actually use. Old-school bolting, even at the crux, so sack up.
Just left of Angensteiner Verschneidung 5c, the large dihedral crack. Route name painted on.
