Make your way to the pillar on the upper level and pull it back once. Pulling the pillar back will reveal a pot containing a sapphire.
Head over to the yellow lever to push the boulder in front of the orange push block. The pillar you pulled earlier will stop the boulder. go to the orange lever to bring down the boulder on its way to the gray pressure plate. After pulling the lever, go on the gray platform and head to the next area.
Before you move, there is a pot hidden just beside the door you come out of containing a sapphire. This puzzle looks complex but is rather easy and one of the cooler ones. Head over to the orange lever to push the snake on the green pressure plate in turn pushing the rock forward. With the orange push block extended, it will stop the boulder in its tracks.
Head over to the crack and then head over to the blue lever to push the boulder down. Then head over to the crack to fall onto the yellow pressure plate which will push you down onto the gray platform. The boulder should pass on the pressure plate in time for you to get to the next area.
In this next area, just upon arriving, there is a pot containing a Frozen Spider fragment just behind the rock you came out of. There is also a pot containing a sapphire just behind the yellow boulder.
Head on to the main area and step on the yellow pressure plate. Doing so will push the yellow boulder into the crack. The boulder being a boulder instantly breaks the crack giving you a platform to stand on. Now press the orange pressure plate to bring down the orange boulder. go on the white platform and the boulder will press the plate bringing the white platform down. Go to the next area and obtain The Key of Spirits. Insert it into the gate and cross the bridge. However the large snake that has been following you crashes through and causes you to fall into the Maze of Spirits.
