Heya Vertreya Zarran ^^

Mind If I toss a few guidelines here?

Seems you chose to main an Arcanist (be it either Scholar or Summoner)

I would suggest you to unlock both of the jobs right away; it will give you a boost in stats when you will use a Job's Stone. Plus summoning Ifrit - Titan once you will beat it, you won't use the carbuncles anymore. (which is sad, I know.)

Try to push Thaumaturge a little bit (26) to unlock Swiftcast. As a caster-type, it will give you a nice oomph!

Next would be Conjurer (you can unlock White Mage) up to 34 to unlock another cross-class skill: Stoneskin

These 2 skills alone are very worth your time. (I use Stoneskin on my Paladin)

I would go that route first if you plan to play spellcasters.

Else, the process is the same ^^

For the rest, by the time you will be lvl 50 and unlock all that the main story has to give you, perhaps all 13 Turns will have the Echo buff (boost to nerf the content), I wouldn't worry about it.

Hope that helps.

Have fun, the most important point! ^^
