Any ideas on FE5 enemy growth?

[VincentASM]

It seems FE5 has the most mysterious method of handling enemy stats. Does anyone have any insight on how it works?

Here's the data that I know, including some samples that I collected:

When the base HP value in Nightmare is around 250, this doesn't mean a negative base, but indicates the enemy uses generic growths and seems to ignore the character's natural bases and growths. The same value also tells you which set of generic growths that they use:

255 = Non-promoted physical

254 = Non-promoted magical

253 = Speed

252 = Promoted physical

251 = Promoted magical

250 = Strength + Speed

249 = Arena (normal)

248 = Arena (Thief)

247 = Long-ranged

(Info derived from Pegasus Knight and the Japanese hack uploader site)

Looking at growth set 255, I recorded the stat additions for around 20 of the same enemies and came up with this:

Level 1

(Min - Max / Avg)
HP  0 - 3 / 1.36
STR 0 - 3 / 0.93
MAG 0 - 3 / 1.14
SKL 0 - 3 / 1.93
SPD 0 - 3 / 1.29
LCK 0 - 3 / 1.79
DEF 0 - 3 / 1.64
BLD 0 - 3 / 1.43

Level 10

HP  3 - 8 / 5.07
STR 1 - 6 / 3.07
MAG 0 - 4 / 1.93
SKL 0 - 6 / 2.87
SPD 0 - 3 / 1.67
LCK 0 - 7 / 2.60
DEF 0 - 5 / 3.20
BLD 0 - 5 / 2.27

Level 20

HP  7 - 15 / 11.31
STR 2 - 10 / 5.25
MAG 0 - 6  / 2.13
SKL 2 - 6  / 3.44
SPD 0 - 7  / 3.25
LCK 2 - 7  / 3.31
DEF 1 - 8  / 5.00
BLD 0 - 6  / 3.44

The variations sure are pretty large o__o

That Level 1 behaviour looks pretty suspicious as well...

I remember when I attempted to get enemy stats for FE5, and gave up after Chapter 2 because of how annoying variation was. One reset, and a solder would have 0-1 in almost every stat. Another reset, and that same soldier would have 3-4 in those stats. I have no idea how enemy stats are calculated, I just know that they're a bitch to record. As for Level 1s, I seem to remember them occasionally having 4 in some stats. I might have to doublecheck though.

This stuff seems to be right up my alley, so I did some preliminary analysis.

For each of the 8 stats you mentioned, a uniform random number 0-3 is added to the base. In addition, 1 movement is added with 10% probability.

I haven't looked at what happens afterward yet, but I can tell you the generic growths. They're presumably in the same order as the other growth rates, but I'm not sure what that order is.

255: 50 20  3 15 10 15 15 10 0
254: 30  3 20 10 10  5  5 10 0
253: 70 20  0 15 15 10 20 10 0
252: 70 30  5 30 20 30 30 20 0
251: 50  5 30 20 20 10 10 20 0
250: 90 30  3 30 30 20 40 20 0
249: 75 50 50 50 35 35 40 20 0
248: 45 30 30 70 70 30 20 50 0
247: 50 20  3 15 10 15  0 10 0

Nice, that was really quick X D

Looks like another FE mystery is going to be wrapped up I'm really running out of ideas as to what hasn't been solved. I'll probably do some tests tomorrow as well.

Alright, it seems like the data is pretty much spot on. As expected, the order is the same as in-game: HP, STR, MGC, SKL, SPD, DEF, BLD, LCK, MOV.

It seems the auto-leveling is a bit simpler than in the GBA games. With 100% across the field, there doesn't seem to be any variation besides the extra 0-3.

I looked through the whole character data as well and noted down which characters had which growth sets. I found a few patterns in general, although there are a few strange occurences of similar enemies having different growths, or fixed stats. I'll probably post them later when I've refined the results.

An update as promised. It's a little crude, perhaps, but I don't feel like listing the enemies exactly :S
