The First Puzzle
This area is best conquered with the Stone Mask , so that you may defeat the Beamos without issue. You’ll be using the Zora Mask and Goron Mask as well to create statues that hold down the floor switches.
Start by crossing the platforms and standing on the switch, now play the Elegy of Emptiness to create a statue and Hookshot upto the next area.
Blow up the Beamos with a Bomb then put on the Goron Mask and step on the switch, then play the Elegy of Emptiness.
Hookshot up another level, put on the Zora Mask, step on the switch, and play the Elegy of Emptiness. All three blocks are now aligned, cross over to the next puzzle.
The Second Puzzle
This is another pretty simple one. Once you cross over create a statue and Hookshot to the second tier. Defeat the Beamos and put on the Goron Mask, then make another statue on the switch.
Lastly, Hookshot up once more and use the Zora Mask to make a statue on this switch. Cross the bridge you made then start Hookshotting up to the top where an Owl Statue awaits.
At this point you can do whatever you want, continue onward or reset to the First Day so you have a lot of time. You need a bunch of Arrows and Magic in this temple and it’s by far the longest and most confusing one.
Whatever your choice, place statues on the three switches here to create the platforms to enter the Stone Temple.
