==================
2.0 - INTRODUCTION
==================

This FAQ describes the formulas that govern aeon stat increases.  These stats
can increase in three ways:

-Raise Yuna's stats using the sphere grid
-Raise the aeons' stats directly by using the Aeon's Soul
-Fight a certain number of battles

For each stat, the formulas have this form:

stat = MAX(Y, B) + A

where

Y = the aeon's stat value if you'd only raised Yuna's stat
A = the aeon's stat value if you'd raised it directly using the Aeon's Soul
B = the aeon's stat value if you'd only fought battles
MAX is a function that returns the largest valued argument

The MAX function is applied for each type of stat.  For example, the aeon's HP
is computed as if it were based only on the number of battles fought.  Then the
aeon's HP is computed as if it were based only on Yuna's stats.  The higher of
the two is taken to be the actual HP.  The same process happens for each of the
other stats.

Section 3 shows how to calculate Y; Section 4 shows how to calculate B;
Section 5 shows how to calculate A.

==================
3.0 - YUNA'S STATS
==================

Raising Yuna's stats on the sphere grid is the most common and effective way to
increase the aeons' stats.  The only problem is that there's a limit to how
much you can raise them this way.  Yuna's core stats can't be raised beyond
255.  Yuna's HP can go beyond 9999, but the aeons' stats will be unaffected
after that.  Yuna's MP can go beyond 999, but the aeons' stats will be
unaffected after that.

First a note regarding Luck.  The Luck stat is special for several reasons.
The only ways to raise it are to use the Aeon's Soul or to increase Yuna's
Luck.  All of the aeons have a base Luck of 17, same as Yuna.  If you never use
the Aeon's Soul, all of the aeons will have exactly the same value for Luck as
Yuna has while she travels around the sphere grid.

Everything else in this section applies to the other nine stats.  Whenever Yuna
increases any one of these stats, it affects the corresponding stat of the
aeon, but it also affects each of the other eight stats to a lesser extent.

Now is a good time to mention that I got stuck while working on these formulas.
Terence showed me the light.  The main problem was that I needed two floor
functions instead of one in the formula.  Having only one caused my predicted
values to be off by one in a few places.

Terence suggested the following auxilliary stat, which he called the Aeon Power
Base:

PBase = [yHP/100] + [yMP/10] + yStr + yDef + yMag + yMdf + yAgl + yEv + yAcc

When a stat name is preceded by 'y', it's refering to the value of Yuna's stat.
[] represents the floor function, which basically rounds a decimal value down
to an integer.

Examples:

[5] = 5
[5.2] = 5
[5.9] = 5

Here's the formula for an aeon's stat based on Yuna's stat:

stat = [yStat * x] + [PBase * y]

Each aeon has different values for x and y for each stat.  See Section 3.1 for
a list of the x and y values.  Note that the aeons' stats have the same caps as
Yuna's stats (255 for core stats, 99999 for HP, 9999 for MP).  Let's do some
examples.

First, using Yuna's base stats, we'll calculate Anima's base stats.

PBase = [475/100] + [84/10] + 5 + 5 + 20 + 20 + 10 + 30 + 3 = 105
HP    = [475 * 120/100] + [105 * 8]   = 1410
MP    = [84 * 4/100] + [105 * 4/10]   =   45
Str   = [5 * 330/100] + [105 * 1/6]   =   33
Def   = [5 * 100/100] + [105 * 1/5]   =   26
Mag   = [20 * 70/100] + [105 * 1/12]  =   22
Mdf   = [20 * 100/100] + [105 * 1/30] =   23
Agl   = [10 * 40/100] + [105 * 1/20]  =    9
Luck                                  =   17
Ev    = [30 * 50/100] + [105 * 1/20]  =   20
Acc   = [3 * 200/100] + [105 * 1/20]  =   11

Now let's see what Anima's stats are when Yuna is maxed.

PBase = [9999/100] + [999/10] + 255 + 255 + 255 + 255 + 255 + 255 + 255 = 1983
HP    = [9999 * 120/100] + [1983 * 8]   = 27862
MP    = [999 * 4/100] + [1983 * 4/10]   =   832
Str   = [255 * 330/100] + [1983 * 1/6]  =   255
Def   = [255 * 100/100] + [1983 * 1/5]  =   255
Mag   = [255 * 70/100] + [1983 * 1/12]  =   255
Mdf   = [255 * 100/100] + [1983 * 1/30] =   255
Agl   = [255 * 40/100] + [1983 * 1/20]  =   201
Luck                                    =   255
Ev    = [255 * 50/100] + [1983 * 1/20]  =   255
Acc   = [255 * 200/100] + [1983 * 1/20] =   255

====================
4.0 - BATTLE BONUSES
====================

Aeon stats will increase starting at 60 battles, then every 30 battles until
600 battles.  All battles count, even before Yuna joins the party, and even if
you run away.  Boss battles and arena battles count.

--------------------
4.1 - Forced Battles
--------------------

In one test, I used a cheat device to obtain all the aeons very early in the
game, in order to see what their base stats were.  Masamune3 suggested another
test to back up those numbers.  In order to verify the base stats of the aeons,
I used a cheat device to go through the game without having any random
encounters.  This was necessary because in normal gameplay, it's not possible
to acquire all the aeons without passing 60 battles, the first point where the
stats increase.  Below I've listed all the forced battles I encountered:

1 - Sinscales
2 - Sinscales
3 - Sinspawn Ammes
4 - Sahagin
5 - Geosgaeno
6 - Klikk
7 - Piranha
8 - Tros
9 - Dingo, Condor
10 - Water Flan
11 - Kimahri
12 - Garuda
13 - Garuda
14 - Condor, Dingo, Water Flan
15 - Sin, Sinscales
16 - Sinspawn Echuilles, Sinscales
17 - Ragora
18 - Sinspawn Geneaux
19 - Worker
20 - Worker
21 - Worker
22 - Oblitzerator
23 - Sahagin Chiefs
24 - Vouivre
25 - Garuda
26 - Raldo
27 - Chocobo Eater
28 - Sinspawn Gui
29 - Sinspawn Gui
30 - Extractor
31 - Treasure Chest, mole
32 - Spherimorph
33 - Crawler
38 - Zuu
39 - Mech Guards
40 - Sandragora
42 - Guado Guardian, Dual Horns
44 - Evrae
45 - Warrior Monks
46 - Warrior Monks, YKT-63
47 - Warrior Monks
48 - Warrior Monks, YKT-63
49 - Warrior Monks, YAT-99
50 - Grothia
51 - Pterya
52 - Spathi
53 - Evrae Altana
54 - Seymour Natus
55 - Defender X
56 - Yojimbo
57 - Biran Ronso, Yenke Ronso
58 - Seymour Flux
59 - Sanctuary Keeper

After Sanctuary Keeper, the first stat bonuses were applied, but I've only got
59 battles in the list.  Either I missed one, or one of the other battles I
fought had a split and I counted it as one battle when it should have been
counted as two.  After this, there are three more battles necessary to fight
before obtaining Anima and the Magus Sisters.  These are Spectral Keeper,
Yunalesca, and Geosgaeno.  Note that I didn't fight Belgemine at all because
I used a key items cheat in order to unseal the Magus Sisters.

The good news is that the 0-59 stats (or base stats) for Valefor through
Yojimbo are consistent with the base stats I observed from my other cheat game.
Also, the 60-99 stats are consistent for all aeons.  From this I am reasonably
confident that the base stats I observed in my other cheat game are the true
base stats for all aeons.

-------------------------
4.2 - Battle Bonus Tables
-------------------------

The following tables show the stats of the aeons after each battle bonus is
applied.  The 0-59 rows correspond to the base stats of each aeon.  Notice that
Luck is unaffected by battles.

4.3 - Battle Bonus Formulas

Terence also figured out this one.  The above tables can be generated with the
same formulas presented in Section 3.0, but using some "fake stats" for Yuna
instead of her real stats.  The following table lists the fake stats:

Terence also noticed that these fake stats almost exactly mirror Yuna's natural
Sphere Grid path if you activated every node along the way and didn't open any
Locks.

"I say 'almost exactly' because of 600+.  At 600+, the 'fake stats' gain 4 MDef
and 4 Eva.  However, the final leg of Yuna's Sphere Grid path (ending at Holy)
has two +4 Eva nodes, and no MDef node.  Which is, in fact, *very* interesting,
in my opinion.  A design change at the last second?  They followed the path so
*well* up until then...."  -Terence

5.1 - Core Stat Formulas
------------------------

The following formula applies to Str, Def, Mag, Mdf, Agl, Luck, Ev, and Acc:

ns = MIN(99, [stat / 2])

where
ns:   number of spheres needed to raise the core stat by 1
MIN:  the minimum function, returns the lowest valued argument
stat: the current value of the stat to be raised
[]:   round down to an integer value (aka floor function)

--------------
5.2 - MP Table
--------------

In the following table, the first column is the range of current MP values, the
second column is the number of spheres required to raise MP by 10 for the given
range of current MP, and the third column is the number of values in the given
range of MP.
Examples:

Current MP = 15
12 Mana Spheres are needed
New MP = 25

Current MP = 1500
35 Mana Spheres are needed
New MP = 1510

I've listed the third column so that you can see the pattern.  The number of
values in the MP range increases by 3 and 6 alternately.

An interesting side note: If you wanted to increase Yojimbo's MP from 0 to 9999
MP, you would need 53,905 Mana Spheres.  That should give you an idea of how
much time it would take to max out the MP of all your aeons.

5.3 - MP Formulas
-----------------

Xharas contributed the following closed-form expressions which will generate my
table.

mp: aeon's current MP
ms: number of mana spheres needed to raise MP by 10
SQRT: square root function
[]: round down to an integer value (aka floor function)
base: MP level base (corresponding to the first number in the first column of
my table)
span: the number of MP values in that level (corresponding to the third column
of my table)

Find ms given mp:

ms = [SQRT(mp / 2.25) + 10]

Example:
mp = 323
ms = [SQRT(323 / 2.25) + 10] = [21.981...] = 21

Find base and span given ms (when ms is even):

base = 2.25 * (ms - 10) * (ms - 10)

span = 4.5 * (ms - 10) + 3

Example:
ms = 22
base = 2.25 * (22 - 10) * (22 - 10) = 324
span = 4.5 * (22 - 10) + 3 = 57

base of next level = 324 + 57 = 381
range of current level = 324-380

Find base and span given ms (when ms is odd):

base = 2.25 * (ms - 10) * (ms - 10) + 0.75

span = 4.5 * (ms - 10) + 1.5

Example:
ms = 21
base = 2.25 * (21 - 10) * (21 - 10) + 0.75 = 273
span = 4.5 * (21 - 10) + 1.5 = 51

base of next level = 273 + 51 = 324
range of current level = 273-323

--------------
5.4 - HP Table
--------------

In the following table, the first column is the range of current HP values, the
second column is the number of spheres required to raise HP by 100 for the
given range of current HP, and the third column is the number of values in the
given range of HP.
Examples:

Current HP = 725
22 Power Spheres are needed
New HP = 825

Current HP = 31000
60 Power Spheres are needed
New HP = 31100

I've listed the third column so that you can see the pattern.  The number of
values in the HP range increases by 32 each time.

An interesting side note: If you wanted to increase an aeon's HP from 0 (if it
were possible to have an aeon's HP that low) to 99999 HP, you would need 68,171
Power Spheres.  That should give you an idea of how much time it would take to
max out the HP of all your aeons.

5.5 - HP Formulas
-----------------

Xharas submitted the following closed-form expressions which can generate my
table.  Much nicer than the iterative expressions I used before.

hp: aeon's current HP
ps: number of power spheres needed to raise HP by 100
SQRT: square root function
[]: round down to an integer value (aka floor function)
base: HP level base (corresponding to the first number in the first column of
my table)
span: the number of HP values in that level (corresponding to the third column
of my table)

Find ps given hp:

ps = [SQRT(hp / 16) + 16]

Example:
hp = 3533
ps = [SQRT(3533 / 16) + 16] = [30.859...] = 30

Find base and span given ps:

base = 16 * (ps - 16) * (ps - 16)

span = 32 * (ps - 15.5)

Example:
ps = 30
base = 16 * (30 - 16) * (30 - 16) = 3136
span = 32 * (30 - 15.5) = 464

base of next level = 3136 + 464 = 3600
range of current level = 3136-3599
