Tombs, secrets, hiding places. (Rise of the Tomb Raider)

All the tombs were light, there were no problems with secrets and hiding places, and it should not arise.

I don't even know, everything was really simple, but I remember most of all the "Catacombs of the Sacred Waters" (this is where there was a river with a fast flow of the river and 2 boats), I almost immediately reached the relic itself, but tried to return back the same way, fought, fought, I was already hysterical, I died 20 times, then I just realized that you can go out in a different way - the file is unreal xD

And for me, Baba Yaga had the most difficult document. When you have to jump on the decks.

Demian's crypt what is it and how to get there?
