I have been watching my wife play Fire Emblem: Three Houses with my laptop on hand and I've been writing a little program (using the information datamined here at Serene's Forest) for my own playthrough. I figured this tool might be useful for other players too, as it puts a lot of things that I find myself referencing in one fast, easy-to-navigate place.
It has some uses:
Easily reference any character's stat growths in any class you like
Preview expected (average) stat growth over 5, 10, or 25 levels in any class for any character
Enter your party's stats into the program, to see expected growths from where you stand
Reference party support items: every character's favorite gifts and lost items
Character development reference: shows each character's unique Reason and Faith spells, Combat Arts, and other abilities
This is an alpha .1 release, which is to say: it works and does what it is supposed to, for the most part, but I haven't extensively bug tested it yet. It doesn't come with guard rails (so for example, if you tell it that someone has F hp, it might not break.) But right now it works and I'd like to see if anyone else is interested in it or finds it useful.
It is uploaded here, because I don't have anywhere better to put it ... https://gofile.io/?c=ZwPVAr
It looks like this:
Thanks for reading!
