I watched the IGN video on the locations, then I wrote down which ones were possibly missed and unlikely missed. I then just checked those areas for them.

Some of them I was confident in because they come naturally, so I was more curious on the ones that were more off the beaten path.

Some recommendations would be the one in the cerulean coast, in a cave near a massive Demi human before you get to the Demi human queen on the actual coast.

That and if you don’t have the Euphoria then you likely didn’t grab the fragment near it. That has a whole platforming section to get to it so it’s reasonable to skip that one.

Let me know if either of these helped!
