End Game Question

[Tanoxis]

Once you finish the storyline, you can start going, like you said, for your Relic. Also leveling your subclass a little bit more if you need some of the cross class abilities for your main job.

Start gathering tomestones for Darklight Armor, upgrade to Relic Zenith, and probably weapon. Primals, Hard Modes, are part of the Relic Quest, but also can be done apart, they can also drop a weapon. Also, try for the few new Story Missions that patch 2.1 brought up and unlock Crystal Tower.

All of that will help you on your end game equipment. Then you can push to unlock and try the Binding Coil of Bahamut, and Mythology Equipment with other kind of tomestones.

Hope this helps!
