How do i get them? Its for the quest Still in the dark.

Anyone? i cant continue until helped.

Get into the caverns from a lower vault level.. then work your way up thru the caverns to the level where the map tells you the stuff is.. 2 i think..

I have got into the caverns but it just puts me out where i started.

Edit: I found it. It turns out i was in the wrong cave. Thank you kind sir for inspiring me to keep going.
