If you think you've finished the quarry and don't know what to do next, then you probably haven't finished the quarry.

Go finish it again, be more carefull.

I'm willing to provide info on which items I have too, but they will be in boomer terms like "that yellow pew pew staff"

Try going lower?

If you don't know where to go next, the manual will always provide a hint.

You have not finished quarry
