What cool things have you guys found? I've done a cursory exploration of the whole place, going from light root to light root, but haven't spent a lot of time looking at details etc.
Pretty much anything significant in the overworld has an equivalent in the depths, they really went far with that mechanic! I haven't stumbled across a single lynel yet but apparently there's one underneath each stable.
This has been the coolest thing for me. Realizing the shrines line up, then any water, then the entire heightmap. It feels really rewarding to figure that stuff out then use it to navigate new areas you haven't unlocked yet based on what's in the overworld.
I didn't know this about lynels being under stables. So I checked my map, as I had marked each lynel I encountered in the depths, and you're right! Each one is directly under a stable!
Something I'd like to know is what's up with these pillars connecting to the surface? Besides the obvious one, they always seem to be placed at random locations. These things feel like they should nudge you towards something interesting or teach you something, but I didn't get either of those.
I'm not sure how they decided the locations. One in Hebra does take you to the peak of a small mountain, but there's nothing especially significant about the peak itself.
Not going to post any of the really cool things that I consider spoilers, but here are some other things I've noticed which no one has posted yet.
The names of the lightroots are the names of the shrines backwards.
Every little mine has one chest, usually containing 20 crystalized charges, but sometimes a unique item. They are easy to see on the map.
Big monster lairs are easy to spot on the map, too, once you get used to their appearance.
Groves of trees (the little star-shaped dark trees on the map) very often contain a giant hollow tree stump with a chest in it. You can learn to recognize these tree stumps on the map.
After pretty much fully exploring the Depths, I must have found 10 Old Maps where I already had the treasure. Thankfully, the game recognizes this and doesn't waste your time by placing an X on the map.
One cool thing (that not everyone immediately groks) is that each lightroot corresponds to a shrine on the surface (and vice versa) - really useful if you're looking for some out-of-the-way shrines, and you've done some mapping of the area in the depths already.
I don't think the fairy fountains correspond to anything, but the 'Spring of Courage/Power/Wisdom' and the Great Mother Goddess Statue in the forgotten temple all correspond to Bargainer statue locations.
I feel like i have not explored much in TOTK. Though i’ve spent some time under the big mines and there are nice rocks down there, mostly zoonite. I plan to do a heaven and depths exploration now I finish the
