Last I played this, I was near the end of the first part of Digital Devil Saga (it's a 2-part game). There's a particular type of skill/element called 'Almighty', which has resistance to most other skills including physical. They're typically quite powerful as well. I'm in an area where just about every random encounter is some powerful Almighty demon. It was way too difficult for my under-leveled characters to even walk around and fight the 'weaklings'. I could go to the previous stage and level up, get some new anti-almighty mantra and stuff, but instead I put it down to play something else :P I intend to go back to it soon though, I have a friend who wants to borrow it.
