The gear I used for this:

I’m positive had I not used Executioner’s Scythe or Death’s Charge, my DPS would have been higher. Gravedigger didn’t seem to out-DPS Shroud Auto, and suffered heavily from occasional missed crits. Using Soul Spiral as a whirl finisher inside of the dark fields of my wells for the leeching bolts yields 36 Leeching Bolts (3x per whirl, 12 whirls total – all hit while inside of an enemy), dramatically increases initial DPS.
