I'm 200 days in, not much challenge left. I wanted to get a core group of slaves maxed out, but I can't find a reliable way to get the materials. I thought "hard" fighters guild quests would be a good way, but they never seem to spawn even though I've got all points in "hard"

ya, ok. I just looked through the data tables. I guess I should have done that first. I guess "hard" stuff isn't really ready yet, nor are the locations where I'll farm it.
