Contains: Sigil Punishment (Accessory). To get to this chest you must start by moving the large shield covering the entrance to the right. Then you will be able to climb up it to the right side.

Being at the top, throw your axe at the red jar. This will unlock the passage to the other side. You can try to move the column that has fallen over, but this will not yet have the desired effect.

Return to the bottom and move the shield to the left and then climb up after it to the left side.

Go to the other (right) side and move forward the column that has fallen. It will now reach the target position.

Return to the ground and try to move the shield to the right again. The protruding column will make it stop in a position that allows access to the gate.
Use the wheel to open the gate. Then throw an axe at one of the gears on either side of the gate to freeze it. Use the sigil arrow to extend the freeze and recall your axe. Quickly toss your axe at the wheel on the other side to freeze it as well, and quickly, before the power of the sigil arrow expires, enter the cave.

To leave the cave, destroy the chain lock.
