This is a standalone EA include for a fixed growths mode in FE7 and FE8. This isn’t hooked into the skill system so there’s no need to use that with your hack should you not want to. That also made it easy to port to FE7, so now FE7 has access to fixed growths mode.
Stat growth is based a formula that uses your level and growth rates to determine what stats to give. The effect is that your growth rates add and you get a stat for each time they pass a multiple of 100. You start with a completely arbitrary 50 points to make the first level not always empty for most characters (and it also technically has a rounding effect on your average stats if you start from level 1). Because the stat gains are mathematically tied to the level (there is no actual memory of your total growth points) your characters will gain different first level-ups if you start them at different base levels.
Hopefully somebody will get use out of this other than me (because I have plans to use it for some of my own projects) even though I’m sure many are already using the skill system. It was not too difficult to make so it was worth it for me to do.
