I'm level 50 and I want to trade these "life crystals" for a B grade weapon. Except I don't have any. So someone correct me wherever I'm wrong:
1. Items such as Skull of the Dead B-Grade and Dragon's Heart B-Grade can be turned in for a B grade weapon.
2. The only way to get these things is from raid mobs.
3. More specifically, the monsters that the Area Manager of the Adventure guild has listed are the only raid monsters that drop these items (ie. Master Anays, Cherub Galaxia).
4. The only players who can fight these certain monsters to get these items are the Lord or Clan of the castle.
5. A specific item, Destruction Tombstone, can be dropped by raid mobs and turned in for Adventurer's Boxes.
6. Adventurer's boxes are the only way to get other items such as Skull of the Dead B-Grade and Dragon's Heart B-Grade.
7. Higher quality items and life crystals are the same thing.
8. Higher quality items and B grade weapons are the same thing.
9. Higher quality items and party masks are the same thing.
10. Items such as Skull of the Dead B-Grade and Dragon's Heart B-Grade are types of life crystals.
I'm sorry for being so stupid, I can't find any exhaustive explanations to this on the website, and I don't get this system at all.
