in 100CE I got 27 Atmas. I ended up with over 40 in total when I actually handed the quest in and realised you only needed one set. Didn't really grind them, just levelled to 20 normally and then mastered 4 jobs. Knight, Chemist, Oracle and Cannoneer.

Grind is handy this time round. Such a shame that you get everything so fast. Was expecting an actual grind like the good old days. Now it's just back to Tomes which is awful. Kinda wish it was 18 Atmas per relic as now the content is essentially dead now.
