Vex\Atherial armor

Vex's would have a very rare chance of dropping material that could be crafted into an armor. it would be the rarest armor in the game and could only be crafted in the end realm. It would be enchanted with feather falling and the wearer would be able to walk through walls that are only one block thick. and one out of three strikes or so by an enemy has a chance of dealing no damage beacuse of the atherial aspect of it
