We should probably move this discussion to the Demon’s Souls thread.
And by the way, you do have a 100% physical resistance shield already, since as the Knight, you started with the Kite Shield which blocks 100/30/70. That’s 100% of physical damage, 30% magic damage, 70% fire damage.
Edit: Oh, and go to that website I linked to. It’s very useful for looking things up within the game. The game is very obscure on a lot of things. The first time I played it, I was reluctant to go outside the game to look things up, but with these games, I think it enhances the experience to look stuff up on that website, not hurt it.
