Open strings and root positions

3 of the 7 open strings belong to C# Diminished Arpeggio: string 6 E (b3), string 3 G (b5), and string 1 E (b3). None of those open-string tones is the C# root, so the root must be fretted on every string.

Practice this tuning-specific layout

Play C# Diminished Arpeggio on the low A string at frets 4, 7, and 10, saying each note name and degree aloud.
Build a phrase that lets E on open string 6 ring, then connect it to the nearest C# root and two other arpeggio tones.
Connect the C# root positions on strings 7 through 1 at frets 4, 9, 4, 11, 6, 2, and 9, adding the nearest arpeggio tone between each pair of roots.
