So they mentioned a fifth divine beast at the start and I figured it would be a horse, sic the motor cycle, and wondered how and when I'd get it. Well after running around halving your cool downs you flag for one more divine beast back at the Shrine of Resurrection and I was like I knew
that place had to be some kind of thing.
Once you get in there it's like "a new door will open." Surprise!
It's not a new door, the entire room is an elevator so you just go through the same door again.
So I headed to the map and was like, "it's a horse!" and
It's not. It's nothing, just spinning gears.
Anyway.* Let's call room #1 the lava room. Super straight forward, use the map to adjust rotation and run across the pillar and don your fireproof suit. Glide back after dropping the ball on the rail.
* Room #2 is the one directly across from #1 and I just went up the spinning wheel and glide over to it. Before walking in use your magnet to shove the sliding piece into one of the holes to make half the room spin. Enter and ignore the first metal thing, just ride up near the top and grab that one first. Shove it into the thing at the bottom then extend the other piece out to start spinning the second one. Move it back one you line the door up on the bottom then just chill at the door waiting for the power line to line up.
* Room #3 is the one on the same side as the first, pull the metal rod out and slide it into the space above then pull the other section out to latch onto it. This is the air room and it is also pretty obvious. Glide over, change rotation, glide over, Stasis the fan, glide to the lock.
* Room #4 needs you to Stasis one of the rocks to lift the platform up to enter it. Inside side the bottom part of the assemble to spin the next platform up, Stasis and hit the thing hard to lower the water, then when you stand on the switch you'll find a ball to launch back to reraise the water up.
With that you can open the door so use the magnet to shove the final part into the door and spin it open. You'll see the monk hosting the trial inside just run in and talk to him. Afterwards you'll get a memory and a collectable picture of the Ballad.
Trust me when I say if you're a little confused on what to hit with you're sword, you should throw a banana on the ground and wait to see what happens.
