Let me walk you through the most reliable ways to get your hands on spectral dust, since it's pretty crucial for those endgame items (especially that phantom veil cloak you might be eyeing). The basic approach starts in the cursed forest, where those ancient villages in the northwest are absolutely packed with spectral warriors like banshees, and here's why that matters - each level 62 banshee you take down guarantees a dust drop, which is exactly what we want.

Something interesting about this whole process is that once you manage to defeat foulrot the soultaker (that nasty level 62 boss lurking in the eastern forest), you actually unlock a much more controlled farming method. The tomb structure lets you spawn your own banshees using 8 gem dust and 24 plague brier, which is pretty clever when you think about how it lets you control the spawn rate. If you're more into the crafting side of things, the advanced grinder setup becomes available after foulrot too (and between you and me, it's often more reliable than hunting).

A little tip that's helped me quite a bit - try combining your dust runs with visits to witch huts, since you'll need those scourgestones for crafting anyway. And while you're getting everything set up, having your servants run missions to the cursed forest can really help supplement your supplies (they sometimes bring back decent amounts). Just make sure you're properly geared before heading into those ancient villages - level 70 equipment is pretty much essential, and bringing some good aoe abilities will make your life so much easier when dealing with groups.
