General demographic of causes of death in Dark Souls:
- 1.2% - Invaders.
- 2.1% - "What the-- oh."
- 3.0% - "Oops."
- 3.7% - "FUUUU--"
- 45% - Smough[*]45% - Ornstein
Again, just because it was hard doesn't mean it wasn't fair. After the first time I beat them and knew how to handle them better, I had no problems with subsequent characters. I'd say that was one of the best fights in the whole game.
