Hia Miu Shrine is a Shrine from The Legend of Zelda: Breath of the Wild. It is located at the far northwest corner of the Hebra Mountains. The Sheikah Monk Hia Miu offers the "A Major Test of Strength" trial and he will give a Spirit Orb to Link upon completion of the trial.
This trial is "A Major Test of Strength". In this test, the Guardian Scout IV is equipped with a Sword, a Spear, and a Battle Axe. Once it is defeated, a door on the far end of the chamber opens revealing a chest containing a Sapphire and Hia Miu's enclosure.
