After my usual routine, I filled the only backpack I had now with some provisions, then upgraded the 'Void anchor' skill six times, reaching its maximal level. Then shadow walked to the ogre cave. The idea was to get some more points and then focus more on putting the anchors close to a bunch of hunting grounds, so I could cover multiple of them at the same time.
This was the golden time for me, as I didn't have to share those places with others at all. I only wished that I had some kind of way to transport easily all of those crystals without dragging carts with me because that was annoying.
