The game box includes a number of sealed boxes and envelopes, each designated with a symbol or letter.

At certain times, the game will direct players to open one of these. If it contains materials for a new character class, that character class is now available for anyone starting a new character.

If the envelope contains other contents, the contents will direct the players how to use them.

Players will be directed to open boxes or envelopes when they complete personal quests or meet specific conditions.
