Ishokin Shrine (Rauru’s Blessing)

How to find it

Ishokin Shrine is at map coordinates -565, -3524 (height 142), on a ridge in the Faron Grasslands, a short glide southwest of the Popla Foothills Skyview Tower. Examining the sealed shrine makes a beam of light point toward the crystal you need. The crystal belongs to Baddek, who waits beside the only campfire on the south side of Zokassa Ridge, and he will only hand it over for a Giant White Stallion.

Solution

Carry the crystal to the shrine

The shrine is sealed until you bring it a crystal, and this is the Ride the Giant Horse shrine quest. Follow the beam of light to Baddek and the crystal. He will not give it up unless you show him the Giant White Stallion.

1. Catch the stallion at the dead end of Ibara Butte, past the Horse God Bridge southeast of Highland Stable (about 803, -3718). Sneak up from behind and mount it. Taming takes several stamina wheels, so bring stamina food, or freeze it with an Ice Fruit arrow first. A Talus sits near the west side of the bridge.
2. Optionally register the horse at Highland Stable so you can summon it later.
3. Ride it to Baddek on Zokassa Ridge and he gives you the crystal, a shrunken shrine.
4. Interact with the crystal to produce the green beam, pick it up with Ultrahand and carry it along the beam to the shrine site. It grows to full size there and the shrine opens.
