I am in the Samuels chamber, I have no healing, no one who trades has any either. I have killed one DK and got the key from him. Now I am attacked by another two DK's. They are giving me the hard time, I keep dying. Any sugesstion? I have made a bomb from explosives, where do I put that? Also how do I open the door that is locked in the corridor before I enter the passage that leads to Samuel?Please HELP!
