I need help in solving the quest Rest for the restless, given by Lady Nepente in House Phiarlan. My problem is that i cannot get a gate to open. I have tried the quest three times now and always get stuck at the same spot. it is the gate after you killed the first mage and after the six valves you have to turn to open the first gate (three valves in two different rooms, with spike traps). I manage to open the first gate, but after that I am stuck. Can someone help me? What am I missing?
