I think these are all very easy to get and most of it is affordable. I'm pretty sure you can see what an ideal set up is just by looking at a few other threads in the RNG section, so I wont get in to what you should be aiming for.
Like Lambtor mentioned, the relic legs and feet are the only ones you need. Just try to +1 those two and you'll be set for a long time in the feet/legs department.
And as far as the "How do I hit big numbers as RNG?" guide, here's a quick answer:
It's easy to hit big numbers on anything you fight as RNG. All you need are two BRD's with fully merited Minuet to SV the four Minuet songs on you, another two to SV Sinewy/Herculean Etudes and Hunters/Archers Preludes, a lucky COR with a DRK in your party for DRK's roll and RNG's roll, Dia III, Angon, someone else to land an Acid Bolt, lv. 5 Box Step/Sluggish Daze, Red Curry, Warcry, Berserk, Velocity Shot, Flashy Shot, PPA, merits, amazing gear and a Raise III. Granted, the raise wont help you hit harder but you're probably going to end up needing it.
It's that simple!
Thanks, I have most of that set up so I guess I am not doing too bad. I will try for the items I am missing, mainly body. I just seem to hit for such low damage on anything I fight, it is frustrating......
