Elemental "Cubes"

[OfUnreasonable]

What are these "Elemental Cubes" for?
Like the "Soul Cube of Terra"

Can we use them?
(It'd be awesome to use them to switch Elements. I'm always water in everything, but I got stuck w/ the earth element- Terra)

On a random note: Watching Family Guy and Stewie and Brian end up in the alternate demension where Meg is hot.

I was also wondering about that all the time. Now that you can even gift them, I wonder even more, you cant even sell them? Would be nice to see an answer on that question

They might be the currency for skills , but yea I hope I can change elements , I'd Rather be Mistral then Terra >:
