Oh boy...
Read this opening post. Basically:
1. Avoid all non-boss/story/unavoidable fights.
2. Choose which 6
leaders you want end game from the start. (I suggest unique ones with unique special moves).
3. Choose which units set-up you are going to have end game before you play it. (Yeah I know...You might as well just read the entire Wiki)
4. Don't grind until you are (around) BR 60, Disc 2 and have leaders/soldiers for your final party.
5. Only Grind in the Ancient Ruin DLC (free), on the Ancboilers and Greater Demons.
6. You want to keep your battle rank as low as possible and your status as high as possible.
7. Never switch soldiers, keep the same ones from start to finish.
8. Take soldiers with healing/item arts, not combat arts (because they can only learn combat arts, not other ones).
9. Follow this
topic (and the
Joining one) to the letter to get all sidequests.
10. Talk to all the unique leaders every chance you get to make sure their quest spawn.
This game is a project ... expect 100+ hours to get anywhere near 1000/1000, the only achievements I'm missing are silly ones which I could easily get but after 2 failed 100+ playthroughs and 1 successful one, I can't be asked anymore.
