@nostrade - Full darklight or Vanya/Rose Gold set should be able to get you through Turn 1-3 and maybe Turn 4.

Crafted gear will give you a lot more flexibility to mix and match materia pertaining to stats you want but will cost you hefty $$$. Darklight is just straight up selling all your soul grinding for philosophy tomes. They are both similar stats-wise, but crafted gear will pull out ahead by a bit, and you can dye them.

You're definitely going to need Myth/Allagan gear to tackle on Turn 5, though.
