The thing with Demon's Souls is that though the game is initially difficult, you find the design holes and exploit them. After all, you remind yourself, the game is hard, so I should use every cheap method of winning that I can think of. For example, every guide and player swears by using a Thief Ring [reduces aggro range] so that you can always have the first hit on your opponent at a range. In fact, many enemies won't even react to the first hit. Many guides suggest abusing this hole in AI/Game design as much as possible from the first foe to the final boss.
