well hard to say what needs to be done for 1.23 im guessing Castrom Novum (sp?) might need to be completed so I would aim for that, also getting your MNK fully unlocked is a must. To do this you may need to venture into darkhold to either clear the quest to unlock AV or might need to get a piece of your AF in there (cant remember been a while since I did MNK).

there is a couple things I would aim for, also aim for highest GC rank as well.
