Indeed. I also found the cave first but left because I figured I had to some side quest first. The quest is the last in a 3-quest questline. The first one can be triggered at East Akkala stable.
I bought the locations for the first few but then I realized their locations matched the ones of the Goddess's statues in the surface, so I found the rest using that.
I'm close to beating Age of Calamity. I'm also replaying OOT 3D. I lost my original copy and got a new one a few years ago, but I hadn't beaten it in the new one.
In Hyrule Field you can find the Ranch Ruins. Sure, there have been many ranches, but the ruined buildings and fences arrangement resemble Lon Lon Ranch's. There's also Mabe Village Ruins, Mount Daphnes. The entire game is full of references.
Several people have reported that the Joycon have a syncing issue where what you described happens. Thankfully my Joycon seem to be working perfectly. I hear nintendo is investigating the issue and will hopefully address it in a future update.
So I'm missing just one Kinstone fusion, and i believe it is the one that restores the tree on the right in the Western Wood. Anyone know where is that fusion?
I'm sorry if this doesn't belong here...
So are you suggesting another split? I guess it would make sense if Link, Zelda, and Groose returned to their original present after defeating Demise in the past. That leaves their present unaltered, and the past with Demise dead is the new timeline. But that wouldn't explain the Master Sword...
That two Zeldas theory can be solved with Demise being "divided". When Link defeated him in the past, he wasn't completely destroyed, so Zelda didn't wake up in the past.
Okay, so I think everyone that has beaten this game can agree that the ending makes no sense. How can the game happen if at the end you destroy Demise in the past? It's a grandfather paradox too big to ignore. You could say that the timeline is split when Link goes back to the past to rescue...
