So, Character Creation.
This list provides a good basis for base stats (stats for a lv.1 character). Of course, PC's are speshul, so that should get tweaked a bit. Ditto for
growth rates.Tentative example:
Pierre is a Lv.1 Mercenary. As such, he should be a well-balanced character, not slow, reasonably durable, does flashy moves with a sword.
A mercenary's base stats and growths are as follows:
HP: 18 (80%)
Str: 4 (40%)
Skl: 8 (40%)
Spd: 8 (32%)
Def: 4 (18%)
Res: 0 (20%)
Con: 5
Mov: 9
Movement and Constitution are usually static, so they aren't affected by Growth rates.
Of course, as a PC, his stats diverge from the norm. I dunno if it's balanced, but I think that substracting a constant and adding a random die roll should work. Like, I dunno, -2+x(-20%+10*x%) where x=1d4.
So with rolls of 2, 4, 3, 3, 4, 2, Pierre is a lucky bastard and has the following stats:
HP: 18 (80%)
Str: 6 (60%)
Skl: 9 (50%)
Spd: 9 (42%)
Def: 6 (38%)
Res: 0 (20%)
Luck is kind of a oddball. However, the sum of said rolls divided by 2 would be a good measure of his luck since those numbers are obviously luck-related. So Pierre would start out with 9 Luk.
I also don't believe Luk should be a stat that goes up with a level, since it's not something that you can actually train. Maybe it should go up whenever he gets two rolls below 20 on a d% in a row or something. Or you just increase it with Lv ups anyway. I'm not the GM so I'm not to judge.
And while we're at it, promotion.
Let's say Pierre has finally reached Lv.20. He could obviously become a Hero (increasin his stats by a certain amount and eneabling him to use axes).
However, his style is more akin to that of a myrmidon, dealing quick and precise hits instead of taking damage while dishing out hard blows. So instead he could ask to become a Fencer (or whatever you'd want to call it), changing his stat gains in favor of skill and speed, and instead of axes he gets Continue, a skill which gives him an extra attack which a chance of Skill/2 % (or whatever formula you want. FE4, the game the skill comes from, uses attack speed+20%, but that's kinda broken)
