poison is cool in pvp cause it messes up heals + DoT if you can stack that with a bleed weapon it's even better. Just be careful with the block stab it's easy to parry, though i personally never block and just 2 hand all the way.
well generally you can roll out of any large sword combo, i suggest trying to get blueblood sword or upgrading a knight sword to +10 or +5 quality depending on your stats. penetrating sword is kinda :(
you should go back and check the corner after the gate, he walks there after you open it for him, and sometimes when you talk to him it wont register so you have to do it again.
i agree with lanien here this best lookin console game ive played. i like to think RE5 looks a nicer though, but thats not out for a while so who knows o-o?
