Blades of Prey

Grab the sapphire from the pot at the far left of the screen. Head towards the gray platform that the saw blade moves to but don't get on it yet. A stone bridge is visible in the background. Under it, you see a very well-hidden pot containing a sapphire.

Now cross the gray platform by using the lower passage. Head to the lower gray lever. Pull it to move the saw over. Head over to the upper gray lever and pull it to move the gray platform back. Move back to the lower gray lever and get the saw into the platform. Pull the lever again to let the saw blade go to the left most slot. Pull the lever again to lock it in that area. Now go and pull the green lever to let the spider on the pressure plate. Head to the next area.

Move once and to the bottom-left of the screen, behind the pillar that is supporting the platform you are on, and under some orange beams is a pot.

In this area you immediately see six snakes, two spiders and a saw blade. Step on any of the two pressure plates to move the blades around and kill four of the six snakes. Once you have killed the four snakes, place the saw blade back in its original position and cross the gap. Next, kill the two snakes by the levers. Start with the snake on the green lever. Pull the lever afterwards. Next the orange lever to move the orange platform. They will press the plates to allow you to descend safely towards the exit to the next area.
