The Two Rings
Kass is playing the accordian out in the West Hyrule Plains. More specifically, he is just southeast of the Ridgeland Tower. You will find him near a curious formation of ring-shaped rocks. Talk to him for this Shrine Quest.
To unlock the Shrine, you have to find the two ring-shaped rocks that will allow you to shoot through two in one arrow. Obviously, most of them are set up such that it’s impossible. Go to the western portion of the area and you will see a ring jutting out from the hill.
This is the location, shown in the screenshot above. As you aim your arrow, look to the left to see the second ring. Then, aim above that ring so that your arrow can arc through the air properly. You do not need a bow with long shot for this, although it can certainly make the task easier. If you miss, you can retrieve your arrows so that you don’t waste them.
Once you have gotten the right shot, the Sheem Dagoze Shrine will rise up from the ground, completing this Shrine Quest.
