It's my vote for coolest setting that a Final Fantasy game has ever taken place in. That said, don't level grind as it's pointless. Just play the game naturally and have fun. Take some time to understand the
all of the gameplay systems and to understand what you're doing, though.
Learn the following things:
Junctioning
Card Game
GF Abilities (specifically, abilities like Card Mod and ones with names like "I Mag-RF")
You shouldn't even have to Draw grind ever, really. You can just use the modding & refining abilities to turn your inventory into spells. There's also not really a need to make yourself hilariously overpowered. If you're smart about your junctions, you're not going to run into anything in the game that requires you to be completely & utterly optimized. That said ... even if you want to obtain 100 of a certain spell, (e.g. Curaga) from early game sources, it isn't anymore more than a small detour of 5-10 minutes depending on the rarity of the spell and the speed at which you have battles set.
I will echo was
Gradon said, though. Against every single boss, take one turn to use Draw against them. There are some one-time-only draws (only takes one action to obtain) from bosses.
An example of Card Mod being amazing with an extremely common card:
- Abyss Worm card converts in 1 windmill with the Card Mod ability
- 1 windmill converts in 20 Tornado with the T Mag-RF ability
- 5 Abyss Worm cards gives you 100 Tornado
- 100 Tornado immediately thrusts the following categories into ridiculous tier: HP, Strength, Magic, Speed, Evasion
All of that with a handful of playing cards.
