Using The Trap

Grab a torch and go in the center of the snakes. Collect the ruby from the pot that is far into the background. It is just above the left-most arrow wall.

Kill the snake to the lower right and continue on up the wall to the next area.

Climb up onto the main area. go show yourself to the lizard on the right. Go down and hang on the side of the wall to avoid the arrows the lizard will have triggered. Get a torch and grab the ruby from the pot hidden under the right-most orange arrow wall.

With your torch, go kill the snake on the left. Don't kill the snake on the right first because the other snake will get scared and step on the gray pressure plate. Go in front of the lizard to lure it. Position him at the gray wall of arrows. At the corner, he can no longer back away and you can now kill him.

Climb up the elevated area and a pot can be seen in the background containing a Blood Salamander fragment. Use the spear to kill the snake above. Head to the next area.

Get in front of the lizard and push the pillar towards the gray wall of arrows. Then go around it and push it this time along the wall of arrows towards the empty space between the three gray plates. With the pillar blocking one of the arrow walls, head over to the right most plate and step on it. This will also kill the lizard. Pull the pillar to the lower right. Then push it all the way near the entrance. Go around it so you can push it from the other side. Push it all the way to the end of the path. Go around it and push it towards the two plates.

Grab the ruby from the pot hiding under this whole area. It can be seen just under the middle gray platform and a little bit to the right. After you have pushed the pillar to the left-most gray platform, head to the next section.
