Explorer Medal maps

I believe that the "Cave of Life - Entrance" isn't the cave of life itself, but the map before it with the Cornian NPC, which pretty much everyone can enter, as long as they have enough HP/Dark Sight. It wouldn't make any sense if you had to be able to HTPQ (which would mean you're in the 4th job already, which means you already have the 4th job medal) to get a medal worse than the 4th job medal. On the other hand, this is Nexon I'm talking about but it won't hurt to try.

I'm 9/10 at Minar Forest and went to the Cave of Life-Entrance, and it didn't register. Someone I know that got the Minar Forest medal said he had to HTPQ for it to register.

And HTPQ is lvl 80+.
