Mozo Shenno Shrine
This Shrine is easiest to find if you take the Shrine Quest "The Bird in the Mountains". Learn about this Shrine Quest here. Of course, you can also discover this Shrine by finding it on your own.
When you enter, you will be confronted with a trial by combat. Since this is a Major Test of Strength, you will want to make sure you are properly equipped. Bringing healing and buffings foods can help as well if you take a lot of damage.
This particular Shrine has no columns for you to hide behind if the Guardian Scout does its spin and charge attack. However, there are metal blocks on the ground. You cannot pull them all the way out of their spots into the air, so you can't do fun things like drop blocks on the Guardian Scout. But you can pull them up partway and then they serve the same function as columns. If the Guardian Scout hits a block you pulled up when doing their spin and charge attack, they will be stunned and open for attack.
Once you have defeated the Guardian Scout, pick up any of its gear that you want. Open up the nearby treasure chest for a Diamond and then continue on to speak with the monk and receive your Spirit Orb.
