The Legend of Zelda: Tears of the Kingdom Lightcast Island has a mystery that awaits you.

Here's our guide to help you complete the Lightcast Island puzzle for the Ga-Ahisas Shrine in Zelda: Tears of the Kingdom.
Lightcast Island mapIt can be a little tough to reach it for newcomers. Instead, your best recourse is to return later, at least until you've acquire more Zonai Devices, such as Wings, Rockets, Fans, and Batteries. Once you have what you need, you can head to the Hebra Sky Archipelago, normally reachable by way of the Rospro Pass Skyview Tower. As you keep heading south, island-hopping in the air, you should see a few with scattered Zonai Devices, too.
The goal is to build something akin to a Rocket-and-Fan-powered Plane, so you can reach islands that are higher up. From there, you'll notice Hover Blocks guarded by Constructs. Take them out, and attach their Rockets for a huge verticality boost.

Use Ultrahand to rotate these so that the light passes continuously to the end of the tunnel.You can also pick up some loot from chests, such as 3x Mirror and a Star Fragment.

It has a Mirror Shield, which you can flip so that it can still reflect the beam. This will let the beam hit the target in the large chamber. If the angle is wonky, you can use one of the Mirror devices that you just looted from the chest.
