East Luterra also has an Adventurer’s Tome, which requires seven collectibles. These can be obtained by killing enemies, jefes, or as quest rewards, and one of them is known as the Black Fox Flag.
Because the Black Fox Flag is the final collectible in the East Luttera Adventurer’s Tome, it is the most difficult to obtain. We received ours as a reward for completing the Final Battle quest and retaking Luterra Castle. This is not a foregone conclusion.
