Toxic Swamp - Gold Owl and Ball-in-Fire-Pit Reward Challenge - Part 2

This sequence is also shown in a short video walkthrough.

After obtaining the Gold Owl Artifact, as described in Part 1, if you don't care about the reward challenge, just return downstairs to the ball, push it across the last row of spikes and roll it into the firepit. Then jump over it to the exit.

If you do want to try the 30-second challenge, quit the game and continue. As long as you don't move the ball into the fire pit beforehand, the dungeon will reset so the rolling ball trap is still intact, but you'll still have the artifact. (You can also kill Lara to reload, but you'll lose points that way.)

This time, plant a bomb near the axle of the trap, wait for the ball to roll around so it's almost in line with the stairs.

Then detonate the bomb. (The timer starts when the trap is destroyed.) Momentum should then send the ball rolling down the stairs and across the first spike trap. If it lands on the ledge to the right of the stairs, quickly push it off the edge.

Follow it down and then run/roll across one of the clear sections of spikes.

Push the ball around the pods and either down the next flight of stairs (as indicated by the broken arrow in the screenshot above) or off the ledge so it lands on the level below (solid arrows).

The next level has no spikes, just a lot of poison pods. Again, roll the ball around them if possible. Give the ball another push and let it roll down the stairs. . .

Finally, grab the ball and guide it into the fire pit..

Your reward: an AMMO POWERUP.

NOTE: If you reach the lowest level with the ball but don't think you've made it within 30 seconds, you can quit and continue to try again. But once the ball goes into the fire pit, a checkpoint registers and the ball remains in the pit from then on. You'll have to replay the level for another chance.

Gather any gems you may have missed earlier and exit past the now-plugged fire pit.
