Practice this tuning-specific layout

Play C Diminished Arpeggio on the low E string at frets 2, 8, and 11, saying each note name and degree aloud.
Play the arpeggio without using an open string, then stop on the nearest C root each time the line changes strings.
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.
