The Sihajog Shrine can be found on Valor Island in the South Lanayru Sky Archipelago above Tarm Point in eastern Hyrule.
In order to make the shrine appear, you’ll first need to complete the diving ceremony on Valor Island within 35 seconds. After doing so, head inside the shrine to begin the Rauru’s Blessing challenge, which is to just walk up to the altar and grab your Light of Blessing. Along the way, make sure to loot the chest to receive a Diamond!
