The safe door, at Krampus castle, is locked. Last time, when Cisco got his stuff from there, it was unlocked.
Examine the door.
How does the door work?
Tell me how to open it
You can turn the handwheel right or left. You have to raise all spikes so that they point outwards.
Left, Left, Right, Left
If you already tilted it tro turning the handwheel until you get all the spikes pointing inside the blue area. After that, do Right, Left.
You will find a black orb.
