Oman Au Shrine
This shrine is the first one you'll visit and the Old Man will point it out to you after you activate the Great Plateau Tower.
Make your way over and head inside. Interact with the podium on the left to get the Magnesis Rune which will give you a big magnet, basically.
Use your new power to life up the metal plates on the floor and head down the ladder.
Use Magnesis to pull out the metal blocks from the wall and climb over.
Cross the metal plank in front of you, and then use Magnesis to pick it up and make a bridge to the next platform.
Once you're on the other side, look up to the left to spot a metal chest. Use your magentic power to drag it over. The Traveler's Bow is inside.
Now yank open the doors and the the shine is finished.
