How to Complete The North Hyrule Sky Crystal Shrine Quest

Find the Shrine: Start at Thyphlo Ruins. Activate the nearby Skyview Tower and use its boost to launch yourself into the air. Glide towards the Northern Sky Hyrule Archipelago and land on one of the islands. Look to the right to find the shrine's location, which will initially appear to be missing. Activate the shrine to begin the quest.

Locate the Crystal: The quest hint states, “Seek the crystal connected to the beam and offer it to the shrine. Do so, and I will grant you a light that banishes evil.” The crystal is on a large, round sky island visible from the shrine. A Flux Construct I boss guards this island, with the crystal on its back.

Acquire the Crystal: You can defeat the Flux Construct I to get the crystal, but a quicker method is to use the Ultrahand ability. Glide to the platforms above the Flux Construct and use Ultrahand to grab the crystal when it comes close enough.

Transport the Crystal: This is the most challenging part. Take the crystal to the small circular platform on the island where you acquired it. Fuse the crystal to this platform. Then, fuse several rockets, scattered nearby, to the platform. Aim most rockets upwards and at least one towards the shrine's location to create enough upward momentum and the correct angle for travel.

Return to the Shrine: Once the rocket-powered platform is ready, use it to travel back to the shrine's location. When you arrive, detach the crystal from the platform and take it to the shrine.

Complete the Quest: Placing the crystal in the shrine will activate the Mayam Shrine and complete The North Hyrule Sky Crystal Shrine Quest.
