Mozo Shenno Shrine is a Shrine from The Legend of Zelda: Breath of the Wild. It is located in the Hebra Mountains north of Rito Village. The Shrine is associated with the Shrine quest "The Bird in the Mountains", but may be accessed with or without it in your Adventure Log. The Sheikah Monk Mozo Shenno offers the "A Major Test of Strength" trial and he will give a Spirit Orb to Link upon completion of the trial.
"A Major Test of Strength"
This trial is a major test of strength. Multiple Shrines contain tests of strength ranging from "minor" to "major" with "modest" being the middle ground. The only difference between tests of similar difficulty are the weapon set used by the Guardian Scout that Link is tasked with defeating; in this test, the scout 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 Diamond and Mozo Shenno's enclosure.
