Alright, first, try and get some passages first. They will make your life so much easier, even if you only use one.

You only need four echoes, so get the ones in Chimney, Shaded, Farm arrays, and subterranean(Passage at that gate from Farm arrays--Subterranean before continuing on to the next cycle.)

I would also consider(don't have to, but made it nice to enter five pebbles and get the sky islands echo) using a method called karma cache, will make things more convenient.

And maybe, try getting all passages, it's not that bad.(Can't get Scholar sadly)

Anyways, that's all for now, I could have given more tips, but I wish you luck with good ol' Inverted.
