Yes, it was worth blowing up at least once over. Thanks a lot!

Outside the portal fortress there is a button on a wall. At the end of a passage are two blue boxes with button to push in the middle. A message comes up saying "Class D Magical Protection Required." If you press it you die. I'm near the end of the game and I never found anything else that mentioned Class D Magical Protection. Are those boxes openable or are they just there to blow you up? Thanks.
