Here you can find some useful tips about best ways to grind levels and equipment early to mid game.
Tips and Tricks
Actually, just play the Main Story. You’ll naturally get both as you progress. You can worry about grinding when you’re on post-game.
However use random dungeons for gear, food dungeons for levels.
You don’t need to do ANY grinding early on. If you want to do some, 3-4 I think is the best starting one.
Personally, I do my first grind to mid 60s in chapter 6 or 7 (I forget which off the top of my head, but it has infinite enemies).
Most weapons you will be fine with just progressing through the story and leveling your merchant (also discounts! yay!).
But the best weapons will be higher level free dungeons. But here’s the thing, weapons only matter for what skills you’re using.
Weapons are a minuscule fraction of a given stat late game. It really comes down to the passives you have for when you level.
And honestly, You can make your generic units more powerful than the uniques <3 The uniques just get some cool skills and sprites.
