Burn it up
Zelda: Tears of the Kingdom has a few what I’d call “tricky” tower puzzles, but Rospro Pass is a pretty simple affair. Here’s where it is, and how to open it up for further use.
How to solve the puzzle of the Rospro Pass Skyview Tower
The Rospro Pass Skyview tower is located in the northwest corner of the map: beyond Central Hyrule and Lindor’s Brow. The only thing standing between you and easy access to the tower is a collective of thorns: which you can easily take down with fire. You have options here, but there’s one clear path to victory: Fire Fruit arrows.
Simply queue up your bow (RT), press up on the d-pad, and select a fire-based substance to fuse to your arrows. In this case, Tears of the Kingdom provides copious amounts of Fire Fruit early on, and all you need is one piece of fruit to attach to an arrow to create a chain blaze reaction.
Once the path is open you can enter the tower, interact with the Sheikah device, and unlock the Rospro Pass Skyview Tower for good. Given that it’s near a temple and a major village, it’s a great early tower to unlock!
