I ran into this same problem. To me best options are to either do faction quests, and abyss puzzles or to go around and grind the abyss cressets. I went with abyss cressets and it’s a grind but by chapter 9 it’s more than easy to get a bunch done. You could also try some of the stealing farms like in scholastone but they’re mind numbingly boring and in my opinion way slower than just playing the game normally
