I have a few questions:

   1) How to get into a place which was surrounded by walls in
      *Lost Souls' Dungeon* level 5. The position of this thing
      is something like (3,10). I saw the object by Wizard Eye, but
      I just can't make it.
   2) How to open the door in Great Pyramid in level 5, upper right
      corner? I had answered the 8 questions. Pulled all the six levels.
      What should I do?
   3) How to solve the puzzle of those brothers in Castleview? They have
      another brother in the west of Castleview who will ask you the
      question. I am not good in English, so I need *serious* help in
      this one ( the method to solve this ).
   4) Another question but this one is not really important: How to
      prevent damage from *Cloud Dragon*? I had all my party members
      +100 resistance to element attack. Armor class were +240. My
      human members ( I had three human ) still got serious damage.
      Although I had defeated all the dragons in level 1, I would like
      to know the way to prevent damage.

Any help will be thankful. And, THANKS in advance.
