Practice this tuning-specific layout

Play C Diminished 7 Arpeggio on the low E string at frets 2, 5, 8, and 11, saying each note name and degree aloud.
Build a phrase that lets Bbb on open string 5 ring, then connect it to the nearest C root and two other arpeggio tones.
Connect the C root positions on strings 6 through 1 at frets 8, 3, 8, 3, 11, and 8, adding the nearest arpeggio tone between each pair of roots.
