Test of Will
This Shrine Quest is kind of in the middle of nowhere. You can find it at the top of the cliffs on the north side of Gerudo Canyon, between Nephra Hill and Mount Nabooru. Try going north from the Wasteland Tower, or east from the Gerudo Tower. There is a Stone Talus not far from the Shrine.
Talk to Gorons to take their endurance challenge. Stay inside the ring without losing all of your Hearts until all the Goron’s pass out from the heat. Use heat-resistant armor or eat food with a cooling effect to better withstand the heat. Take the second challenge, with an even hotter arena. Use a Fireproof Elixir or Flamebreaker Armor to withstand the heat. This should take roughly 1 minute. Joloo Nah Shrine will appear once you pass the test. Place the Sheikah Slate on the control panel to open it.
