I am so curious

[Kraugel]

There are some things I wanted to ask:

Are all Chocobos (including gold chocobo), Mask type accessories, oblivion potion, enemy lure, arks, pendant of mastery and ultimate sets fully obtainable as of now? Because some players are fully equipped and I really don't have the idea where to get it.

And is there a chance to hit the 777 in slots?

Edit: Just recently, I tried the nanotech armor. Some fight makes my hp drop to 9 because I got hit once so I tried to switch back the armor that I usually use. My remaining hp stayed at 9 while my maximum hp returns to normal. Is it intentional?
