The mysteries are upgrsded from an origanal item for example:
Save the King and Save the Queen
1. Synthinize them
2. you have them
3. get the items for the weapon again
4. if you can when you synthinize it use a serenity gem ( note: s.g. ups any item a rank ) and on the top it will have a new name
5. new name: Save the Queen +, Save the King +
you can do this on any item just synthinize it with a serenity gem and it upgrades the item, again: Drive Recovery + synthinize with serenity gem = High Drive Recovery
edit: sorry oh well atleast other people know now
