- New areas and monsters
- New extra jobs
- Rank 6 (and higher) missions and quests
- Other higher level items
- Miscellaneous

Some details have already been released regarding new areas and new jobs -- the Summoner class has been of particular interest, bringing with it as it does the series' famous summoned monsters -- but details remain unclear regarding how and when the expansion will be distributed. This expansion, however, is going to be sold in low costs (The add-on for the PlayStation 2 version will ship on DVD, while the PC version's update will ship on CD-ROM). People that do not update will be able to play with the people that updated, but will not be able to enter the new areas. Items in the new expansion are also tradable with non-updated users.

The January patch is just going to be bug fixes, but after January there will be big patches to accommodate the expansion pack (also to include new Named Monsters).
