Okay so I'm scanning around in my strategy guide book and I look on the page for the Hennes Mines. It says that in a small area in the Hennes Mines(Wearing a diamond armlet) there is a 90% chance of getting a knot of rust but there is a 10% Chance of getting a Zodiac Spear (I check if my eyes were lieing to me). Then it also said in the back of the book that you could get the Zodiac Spear at the Necrohol of Nabudis pending special conditions. If this is all true I have 2 questions.

1.Is there a way to wield 2 Zodiac Spears?
2. Do you have to have the condition ( to not open the 4 secret treasure chest in the game) in order to not open the treasure chest in the Hennes Mines.
