So, as far as I can tell there's a list of stats for both characters and for your alchemist store:

Character: Str, Con, Int, Res, Spd, Luk, Hit, Evd, Mov, Cmd, Serv, Skill(?), CP
Garden: Sense
Store: Stock, Sales, Attact, Prices
Workshop: Tools, Skill, Mutate
Room: Knowledge, Clerk

Is there any list anywhere that details exactly what every stat does? (Or at least roughly).

Personally, I can be bit of a math-nerd; so if you have numbers besides the general basics ("Mutate% * [x] = Chance of mutation")- that would be !#@$%! awesome. But even just the general function of each stat would be appreciated.

When Tools reaches 66, all resource costs are reduced to 1 for that type of resource. So something that costs 3 wood instead costs 1 wood. There are other points as well where costs go down, but I don't know them offhand.

No clue what Skill does.

Knowledge unlocks alchemy recipes when it exceeds specific points and otherwise does nothing.

Number of Clerks is exactly what is says.

Most of the stats are self-explanatory, but I've been wondering for a while... What's Service?

CP: If you look at the skills list for a character, each one has a set level of CP cost. CP is the limit equipped skills cannot combined exceed.

Hit is more or less the opposite of Evade. So if an enemy has high Evade, having high hit Hit helps...

Luck is a mystery. Might affect item drops. Or Critical Hits. Though if it does, it's pretty unnoticeable...

Skills: For all practical purposes, having high Skill reduces material cost at workshop...

Tools: I also wonder what it does?...

Knowledge; Aside for event/chapter/item in inventory(like weapon)/NG/ specific recipes, having 250 knowledge should give you access to all recipes raising that stat can give...

Skill affects how fast your alchemy skill level increases.

Knowledge/sense cap seems to be 250 according to the jap wiki though there's other conditions to unlock stuff too(like NG+, visiting certain dungeons, recruiting characters, etc) Don't believe anyone's made a list of what amount unlocks what.

You should take a look in the info section of the dictionary, several stats are explained there, though the specifics(for instance, how much 1 point of tool helps) isn't there.

Number of Clerks is the number of people you can have working in the workshop at once. They help items sell, but can't be deployed in battles. You increase this by expanding your room or making beds.

I'm almost sure Luck affects both your crit chance as well as the opponents. The formula for it is: Crit chance = "Innate Crit chance" + Your Luck - Enemy's Luck. You get the innate Crit chance by adding up the crit from the weapon and clothing. You can check your Innate Crit Chance by right clicking your character in a dungeon or going to their status.

Speed affects attacking order and whether you or the opponent gets 3 turns to attack. If the difference of the speed is 3 or higher, then the higher one gets three turns to attack.

The formula of the hit chance is probably: Hit - Evd = Chance to hit in percentages.

If you go to Info -> Lexicon -> No. 101 - No. 104 you'll see what all those things do.

Tools is a straight % reduction to materials required. 88 is when something that requires 8 is reduced to 1. I don't know if anything has a higher requirement, but 99 tools is the highest theoretical effectiveness of it.

Okay, so it's time for me to ask a question.

Items like the Secret Bracelet, which I think is a special item for Crayl, only gives +15 Evade. Now this seems to be really bad and I'd rather use something like +2 Con. Is +15 Evade that good? Does this item have some special effect that I don't know about?

Evade is always good if you want the mobs to miss him, but well, Crayl is range based, so evade won't help much, I think.

Everything depends on situation. For example:
You have an enemy that has 100 hit and 50 phys attack.
Your Crayl has 0 evade and 30 con.
Statistically +15 evade would reduce dmg by 15%, while 2 con would reduce dmg by 10% (and only physical).

Now, if an enemy had 115+ hit, then +15 evade would give completely nothing, while 2 con still would give damage reduction. Still you need to remember that evade works for both magical and physical attack, while con/res work only on their respective types.

I would say that +15 evade is still better than +2 con, but in rare situations second excels. Still I would give Crayl offensive accessory

Okay so, the workshop stat "Skill" effects how fast you gain Synthesis experience... What exactly is Synthesis experience useful for?
If my Synthesis level is M- does that make the stat "Skill" worth absolutely nothing?
