I made a huge mistake. Once I got the furnace I ate every spirit in there. Devoured em all... MWAHAHAHHA. But then I discovered I was insatiable in my spirit hunger. I couldn't even suppress. You can only do it once per day.
I'd get back maybe 20 points of spirit energy after supressing. Which I did around a bunch of provoked spirits. But then to rest and get another suppression back, I'd die. So I just started using the cheat to refill my spirit meter.
Once My appetite is suppressed enough I fully intend to stop cheating. But I had no save game to revert to that would allow me to not have eaten all those spirits.... oops.
To me, I absolutely hate this game dynamic. I was ready to quit the game before I found the cheat
