Dangerous Colors

Exploration Stage: Crystal Mine
From: Abbot Paku
Description: We are about to find out what it is that keeps the treasure hunter's soul here. Our search so far has led us to a cave where the treasure is hidden and where we have discovered a stunningly beautiful crystal with the help of peacock stone powder. I will try to find out if this crystal is cursed or not. Would you like to find my ethereal one-glass?
Completed: You have found a pair of yugenic single-piece glasses. Did you know? When you use this one-glass, you see the colors of different curses. According to it, this crystal is protected by the most powerful curse. Anyone who touches this crystal should be forever bound to it!
