As a complete noob to the game I'm wondering what to farm. Should I get as many white orbs as possible for king moogle? Or should I be finishing up the story for lapis? There is a lot going on in this game haha.
For King Mog events, it depends on how many bonus units you have. If you have plenty of bonus units, then it's worth buying more stuff.
In general, I prioritize King Mog events in this rough order:
- Tickets
- Event-exclusive weapons or materia (Read Reddit or GAF for advice. generally, if the weapon has an elemental damage on it, then get it. Special effects like evade or LB up are good too.)
- (cheap) 6 star awakening materials
- Star Quartz
- Sacred Crystals (not lately since I have enough)
- Cactaurs (buy only a few at a time, otherwise you will have too many units)
- Giancrysts (depending on my whim. focus on Power, Support, Tech.)
- LB pots
The general consensus is that Purecrysts are not worth it.
As for story, keep in mind that the story sticks around and you can do whenever you want. But there are some nice items locked behind story vaults, so it's worth doing over time as well.
During raid events, it uses a different set of orbs, so you should have plenty of unused NRG for story.
