The Hidden Sanctuary of Dzakusku

If anyone is wondering how to open this sanctuary, here's a little guide:

To open it, you need to get to an island in the sky. The easiest way to do this is from the tower of Mt. Laneiru

Spoiler alert The tower itself is also very easy to activate. Just have a few items of clothing that protect you from the cold or potions. Around the tower rocks fall from the sky. Climb them, use the time return and then plan to the tower. Spoiler

Just use the tower jump and you'll find the island you're looking for very close by

On the island you need to activate the portal and then jump down and pass the minigame with the gate passage. At the end, the sanctuary of Dzakusku will open. If you don't have a shield, there is a sled shield on the celestial island.
