[quote name='darkcecil32']I haven't really started the missions yet; I think I've only beaten 5 non-story missions at this point. I would've thought that getting some Dark Matters and Traps would be one of the first things I should do, since I heard upgraded weapons/accessories help tremendously with missions, especially the end ones. I had trouble beating the Ademchide's in Eden as part of the story, so I can only imagine how "fun" Adamantoise/tortoise and Shaolong Gui's will be.
I have about 650k gil at the moment and was planning on getting that up to 2 million to buy my first trap, going after missions 9-14 to unlock 55 and immediately get the growth egg, and then just farming gil/dark matters to finish everything off. So is this not an efficient way to go about things? What order should I do things to begin my post-game quest?
Ruukishi, I don't know what you mean by perfect save file. I just want to get one of every weapon/accessory at some point and have optimal equipment on the 3 characters [Lightning, Fang, Vanille] that I will be using.[/QUOTE]
In my opinion, you should do mission 55 as soon as possible after beating the story. You don't need to be strong at all to beat it, you just need Vanille's Death spell and some luck. There's no reason to wait.
Once you have the Growth Egg, start at the top of the mission list and just work your way through it. I wouldn't worry about 5-starring everything at this stage; some missions will be tough to even beat.
Once you've beaten all of the missions, start again at the top of the list and return to everything you haven't 5-starred. It will be way easier now, especially since you'll now have the Gold Watch.
By this point you'll probably only have Adamant Will and Treasure Hunter, and possibly Master's Seal, left to do. Use the Elixir trick to beat the Long Gui and get the Adamant Will achievement. It's up to you whether you want to save afterward and keep the 200,000 CP, or reload your last save and keep the three Elixirs you used. Personally I'd keep the CP since you won't need the Elixirs for anything else. If you do already have everyone fully developed though, you might as well reload and keep the Elixirs.
Now it's time to farm. Your two prime spots will be Leviathan Plaza for the Adamantoise there (Trapezohedrons and Platinum Ingots), and the area of Pulse northwest of the Cie'th Stone circle for Shaolong Guis (Dark Matters). You can do this in either order, or mix it up, but I wouldn't attempt the Shaolongs until everyone is fully developed. It will take a little time to work out the strategy and timing for killing Shaolongs but once you do, you'll be killing them again and again with little trouble, and the Dark Matters will come quickly.
Adamantoises are a lot easier than Shaolong Gui. You'll want to Summon at the start of the battle. If you're not developed enough, you can use the Death spamming method, but soon you'll feel comfortable just pummeling them to death. After each battle, you can use the soldiers nearby to recharge your TP.
Two things I would
not recommend doing: farming for CP and paying money for Traps. It's just not an efficient use of time. Even if you play very quickly and efficiently, you'll fully develop everyone's Crystarium a while before you're done accomplishing everything else. And it's never necessary to max your characters to beat an enemy except for possibly the Shaolong Gui. You can check my achievements, I didn't get Master's Seal until after I had 5-starred every mission.
And the 2,000,000 gil price tag for a Trapezohedron is beyond ridiculous. In the time it would take you to farm that much gil, you would have earned several Traps off of farming Adamantoise in Eden.
What I mean about the perfect save is, there are some people who want to have all of the weapons and accessories at the same time, and have an uber tricked out party. But as you know, that's not necessary for the achievement. If you focus on completing your accessories first, and just upgrade a weapon whenever you happen to earn a Trap, then once you have all of the accessories done, you can sell everything you own, and use the money to finish off the weapons you still need. You'll have a bare bones party with no accessories and crap weapons, but who cares, you're done with the game.
Whole deal took me 93 hours, and 55 hours of that was the main quest.
Also, I can respect that you have a favorite group of characters, but I really recommend experimenting with different combinations at different times-- you might surprise yourself. Sazh in particular becomes a bit of a badass in the postgame. Though I agree that Lightning and Fang are the foundation of any great party.
