^ this is what I did. Went full Parry and then Acc on my Sword and Shield. If I need extra threat, which you don't really have to worry about to begin with, then switch out a VIT acc for STR one. 1 or 2 18 STR acc's will out weigh any crit/det combo you put on the Novus. Not to mention on most servers right now, crit and det materia are super expensive.
