From here, where do I go?

From here you have two paths....

Go for AF Weapon

or

Move on to collecting Tier 1 Tomestones for Darklight gear then once you get the Darklight set you move onto AF2 Armor set or Allagan set

Currently AF2 Armor and Allagan set are two of the most powerful gear sets in the game with equal Defense stats but have different stat bonuses.
