Once you find your way to In-isa Shrine in The Legend of Zelda: Tears of the Kingdom, you’ll find it as easy to complete as Ukouh. This is because we’re in the midst of another tutorial. While the first shrine taught us how to use Ultrahand, the point of the second Great Sky Island one is to master Fuse so you can alter your weapon or shield in The Legend of Zelda: Tears of the Kingdom.
How to use Fuse to complete In-isa Shrine in The Legend of Zelda: Tears of the Kingdom
After you enter and learn Fuse, you can pull a Rusty Claymore from the ground. I had too many weapons in my inventory to grab it initially and had to press the right directional button and select a Wooden Stick to drop first. When you have the Rusty Claymore equipped, select Fuse. You can then run up to one of the boulders and fuse the weapon to it, turning it into a Boulder Hammer and increasing its strength.
Now, the point here is to get rid of the cracked stone door so you can proceed. Swing the new Boulder Hammer and it will be destroyed. Also, the cracked pillar in the back and on the left in the next room can be destroyed to get a chest with arrows.
The next challenge involves making fire arrows. Head to the room on the right, and you’ll see plants with Fire Fruit ready to be picked. There’s also a bow and some arrows. To attach the Fire Fruit to one, hold ZR, press up on the directional pad, and select the Fire Fruit. Note that the arrow will immediately be shot when you release the trigger.
To open the door blocking your way, you need to get the chest suspended on the back wall of this room. Aim an arrow, attach a Fire Fruit, and shoot at the wooden platform it is resting on. You’ll then get the Small Key you need.
The final part involves being in a room with a rock-tossing Soldier Construct. Quickly climb the ladder to your right to get behind the barrier and pick some more Fire Fruits. This gets you out of its line of sight. You can then pick it off with fiery arrows from that perch. It drops a Rock Hammer and Construct Bow. You can then smash the cracked wall to get to complete The Legend of Zelda: Tears of the Kingdom In-isa Shrine and get a Light of Blessing.
The Legend of Zelda: Tears of the Kingdom is available for the Nintendo Switch.
