Board notes 5 details

Layout: A purple dragon vault combines a line clue, pendulum, height bars, compass letters, sliding blocks, and hinged metal plates.
Goal: Translate the sound-and-height clue into the compass, then construct the final key.
Opening: Take the telescope and hammer, inspect the line clue, and strike the pendulum.
Danger Zone: The compass requires both the correct letters and the central eye orientation.
Mechanics: Sequential physical clues culminate in a sliding-block escape and a spatial folding puzzle.
