Is this rune unreachable?

First of all, hello! This is my first post here ^^ got addicted recently, and playing madly. Anyways...

I'll repeat the question I asked in the chat a few minutes ago, but with the help of a picture:

Can an item be totally unreachable? I am asking because I think the rune to the right of my character is impossible to get. Consider this:
- This is a vault, and all the stone walls are non-diggable
- The glass wall is diggable, but there's lava in the way
- The gem portal skill does not work on non-diggable walls

So, what do you think of it?

I can't access the picture, but from your description, it sounds like you're in a "trick" vault. You have to pull each of the levers and defeat each of the monsters that spawn. Once you've done that, you can access the seemingly unreachable part of the map by clicking on the wall at its right-hand side (i.e., the wall directly opposite of the glass wall which borders the lava). That tile will then transform into a door. If it doesn't transform, then you haven't switched all the levers or haven't beaten all the summoned enemies (they may teleport out of the vault, so you may have to hunt them down).

Really? That makes sense. For me the picture link works, but I think you had the right vault in mind: the one with lava in the center, and many levers causing the center door to open, and access the boss and teleporting symbols.

I'll go and try that.

EDIT: done and working! Thank you ^^
