[REQUEST] Fire Emblem Level Up System and Custom Damage/Accuracy Formulas

Hi there!
I've been searching around a lot for scripts to imitate the Fire Emblem Damage Calculation and also the Leveling System those games have, but I couldn't find something.
So basically those are about three functions at once...

First of all, a script that allows more Stats like for example a Magic Defense or Accuracy. This script has to define the enemy's and actors (basic) values for those stats, as well as equipment/state bonuses.
Then, something to allow the user to create formulas for Damage Calculation of Physical and Magical Attacks (I think one could use the default Attack-F and Spirit-F things, but I want to be able to change the normal formulas) and also Hit Rate (like for example you have an Accuracy Stat and a Reflex Stat and, like, 2*ACC - REF = Hit Rate or something like that).
And then, finally, something for the growth of those new Stats. I thought it would be easy using the Fire Emblem system, where characters have their base values and a growth percentage, that means, every time you level up, there is a certain chance of increasing the value by 1 (or here a customizable value?). If you set the growth 100%, you would then create a more default leveling system, but I'd like to have this growth function, actually. There also have to be maximum stats for each character, so that not everything is decided randomly (and so that a physical character won't have more than, like, 20 SPI, but can achieve up to, e.g., 80 ATK). Probably, this growth function would be better done individually for classes (as you could probably have the idea to change growth and maximum in-game).

And, yes, I've already found a script that creates additional Stats, but they are not enough customizable for me.
I hope that a lot of the functions, that I told you about, are realizable, I personally don't have any scripting knowledge but I understand what scripts do when I read them - or at least the basics - so making damage formulas by scripting would be no problem.

Thanks in advance.

I think that yanfly's melody battle system can handle most of this .
Have a look :

But you said "fire emblem" . you want a tactical battle system ?

Thank you, I didn't know those scripts, they really seem to be quite useful.
But after reading through a lot of it, there is still no function to increase the number of stats actors and enemies have and, as well, that growth system does not exist. They at least have a RES and DEX stat, but you are not really free to do what you want with them. It also seems annoying that you need the complete Battle Melody thing to use a single part, but you can't seem to disable some of the features.

I don't search for a tactical system, I just requested the Fire Emblem Leveling System, no Battle System like the one featured in Fire Emblem. Also, I think, Fire Emblem is a good example of what you can do with more Stats, as, for example, the Luck Stat does several things there like increasing critical rate, avoid rate and also finding items by chance.

So, I still hope someone is interested in that request, as I think it could be useful to create more individuality for games.

But thank you, another time, for the tip with yanfly
