Jojon Shrine (Proving Grounds: Rotation)

Jojon Shrine is a Proving Grounds shrine: your equipment is taken at the door and you must defeat every Soldier Construct using what you find inside, ride the rotating gears upward, and open the chest holding a Magic Rod. The trial is called Proving Grounds: Rotation. The shrine is inside Crenel Peak Cave, about 71 map units from Crenel Canyon Mine. The Nojoj Lightroot lies directly beneath it in the Depths.

How to find it

Jojon Shrine is at map coordinates 1202, 329 (height 40), deep inside Crenel Peak Cave in Hyrule Field. The cave has two entrances, at (1144, 247, 58) and (1349, 296). Break the boulder walls with Bomb Flowers, bomb arrows or a hammer to reach the shrine: from the east entrance, break the rocks on the right and keep right until you see the shrine door.

Solution

Grab weapons and fight the first Constructs

Your gear is taken at the door. Pick up the Old Wooden Shield, Thick Stick and Wooden Stick (or Sturdy Wooden Stick or Gnarled Wooden Stick, depending on your progress) on your left, then defeat the Soldier Constructs that patrol the first area. Five Constructs in all stand between you and the gate, and the last two are tougher, with more health. Take out the archer on the right early; a fire trap guards that side and can be shut off by shooting it.

Fuse and gather better weapons

Fuse Bomb Flowers, flame emitters or other junk to the weapons you find. A Construct carrying a Zonaite Shield drops it when defeated, and the area also has a Construct Bow, Rusty Broadsword and a supply of arrows and Bomb Flowers.

Ride the rotating gears up

A huge vertical gear turns in the middle of the room. Use Ultrahand to attach platforms or barrels to its arms so you can step from gear to gear, and use Recall on a moving part to reverse its direction when you need to ride it the other way.

Finish off the remaining Constructs

Rusty Halberds fused to Bomb Barrels, thrown from the upper platforms, take care of the last Constructs. Check under the gear if you cannot find the final one. A cannon shield on the upper ledge also helps against the Construct below. Your equipment is returned when all of them are down.
