Oaken

I had trouble popping this one. It’s related to getting enough fatigue so that your max health is low. I failed to pop it when I had 8 max health so I thought I misunderstood it and tried numerous other runs but couldn’t get close to 8 max health. So I tried again with enough fatigue to have 7 max health instead and popped it after defeating a boss. If you have issues popping this with 8 max health try with 7. The achievement description could be incorrect.
