The Dam's Edge

In this area, move forward then backward. Continue along the path and drop down the wall to avoid the push blocks. Climb up and keep going. As you reach the end of the path, before going down, grab the two sapphires available here. One is just under the rock formation close to you, the other is on the far bridge in the background. Head down into the door.

In this long path, a spider is triggering multiple push blocks. Head over to the first yellow lever to move the yellow push block out of the way. Doing this also reveals a hidden pot that contains a sapphire.

Drop down on the wall and go back up again. This time the spider should be in front of the yellow push block. Pull the lever to make him fall. Hang on the side and go back and kill him when he passes by. Enter the door to the next area. Here, move forward once then hang on the side. Climb back up and move to the right. As the spider will trigger the blocks again, hang down the wall again and continue to take the lower route. While you are on the rightmost section of the wall, before climbing up, you can see a vase hidden between some rocks which contain another Frozen Spider fragment.

Continue along till the lizard sees you. Head back towards the orange push blocks. Take the upper route at first to make him pass there. Then make a u-turn using the lower path to push him off with the orange push blocks. Head over to the exit.
