no not that...i just found out that there was a secret passage in the way where there are wine barrels in the place so i already got that but i now have a new problem:
As Paul Luther, after i inserted a dagger into the coffin, a secret door opens and there was a green shield up ahead, and i thought i would use the spells to break it down (red beats green right?) so after i used all the red powers, i tried the blue and it doesn't work or either the green. that one got me really confusing and frustrating so i went to get the tips from gamefaqs.com, but it just doesn't make sense so i hope i get a better understanding from you who got through the green shield after the secret door when the dagger was installed into the coffin
thanks
