Here is the data I collected while leveling desynthesis on alchemist, I think it might help you refine your formula

EDIT: With your help, I got it! Here's the formula in Google formula format (where $A2 = desynth skill level, and B$1 = craft level):

=min(IF(($A2+30-B$1)<0,0,IF(($A2+30-B$1)<20,(0.15*(19-min(ceiling(B$1/5),9)))*($A2+30-B$1),IF(($A2+30-B$1)<40,3*(19-min(ceiling(B$1/5),9))+(0.2*(19-min(ceiling(B$1/5),9))*(($A2+30-B$1)-20)),IF(($A2+30-B$1)<60,7*(19-min(ceiling(B$1/5),9))+(0.15*(19-min(ceiling(B$1/5),9))*(($A2+30-B$1)-40)),100)))),100)

In simpler terms:

{dScore} ::= {DesynthSkill} + 30 - {RecipeLevel}
{W} ::= (19-min(ceiling({RecipeLevel}/5),9))

(Essentially, for {RecipeLevel}s 1-5, {W}=18. Every five {RecipeLevel}s, {W} drops by 1, to a minimum of {W}=10 at {RecipeLevel} 41)

min([{dScore} <=0 = 0
     {dScore} <20 = (0.15*{W})*{dScore}
     {dScore} <40 = 3*{W}+(0.20*{W}*({dScore}-20))
     {dScore} <60 = 7*{W}+(0.15*{W}*({dScore}-40))
     {dScore}>=60 = 100],100)

Now I just need the materia and/or exp yields...

[Shunio]

For the exp yield I have some partial data based on the leveling I did from level 5 -> 58.
It includes my current level, which item was desynth and how much exp did that yield.

I'm not sure it can be properly used though, but I included it in the sheet as an additional page just in case

Very minor detail but for wvr you wrote:
"When your skill is a bit higher, grind on Linen Halfgloves. All of their materials can be bought from the Sylphic Vendor for a total of 597 gil (note: they also take five shards)"

It's actually 4 lightning and 3 wind. Anyway, thank you for the guide^^

Just asking, if I only have 50% breaking a garuda weapon, do i have the chance to get the demimateria? Or I need to reach until certain amount of percentage to able to get demimateria? Because I successfully break around 5 or 6 but never get 1 yet.

Just asking, if I only have 50% breaking a garuda weapon, do i have the chance to get the demimateria? Or I need to reach until certain amount of percentage to able to get demimateria? Because I successfully break around 5 or 6 but never get 1 yet.

The data I've seen from various sources appears to indicate that skill level has no effect on yields. There are people reporting a massive drop in demimateria yields with higher skill, and others reporting massive gains with higher skill. Looking over all of the data I've seen, and using my own experiences to back them up, I strongly believe that your skill has no bearing on what you get.

Also, with a 60% chance to desynth Ifrit Blades, I successfully desynthed two of them. The second gave me 3x Demimateria of the Inferno.

The data I've seen suggests that the drop rate for Demimateria is close to 10%. However, the data (which is admittedly a very small sample size) also suggests that items that can give multiple demimateria can also give fewer demimateria with an equal chance. So, theoretically, if Ifrit Blades can drop 3x Demimateria of the Inferno, they can also drop 2x Inferno and 1x Inferno, all with 10% drop rates, for an expected yield of 0.9 demimateria per desynth. But, I don't really have the evidence to back this up. I need more data...

But, if this is right (which it likely isn't), it would make Artisan/Forager tools better than the hats, since for Artisan's, it's 5x the cost for 9x the chance of mastercraft demimateria (since they can give up to 3x at once), and for Forager's, it's 2x the cost for 9x the chance of mastercraft demimateria. Need moar data!

Hello, I can confirm that Battlecraft demimateria III can also be obtained on primal weapons:

Okay! OP updated using the success rate formula to get the cheapest way of leveling (on my server) at skill level 75. Spoiler: it's the 2.2 i90 stuff. ALC is SoL on this front since they don't have any ANY 2.2 i90 desynthable items. Not even housing items. BSM and CRP both have no meldable 2.2 i90 items, so they're a good bit more expensive and chancy to level at skill 75. But, the i90 stuff is still the best. Check out the numbers if you care!

I don't know other server prices, but the Hunt totally tanked the myth mat market on Faerie. No complaints here! Cheap desynth experience for me forever!

[Nyalia]

I have shared my cost calculation spreadsheet (well, a slightly stripped-down branch of it, anyway) if you want to see what the best desynths are on your server for experience and demimateria. Follow this link for a Google Doc that calculates the cost of desynthing various items.

To use it, follow these instructions:

1. Make a copy of the doc so you can edit it (File -> Make a Copy)
2. On the "Desynth Skill" tab, enter your desynthesis skill in each class.
3. On the "Raw Materials" tab, enter the price of the prices of each Raw Material on your server's MB in the MB field. Do not edit other fields on that page.
4. If you want to add a new raw material, add it to the bottom and include the MB price or the crafting mats required as shown.
5. On the "Desynth Items" tab, you can see the prices of desynthing each item, which tells you what's cheapest to use to level or get demimateria.
6. To add a new item, enter the crafting materials as shown, the desynth class, the clvl (recipe level) of the item, and the number of materia slots it has.
7. The "Desynth Chances" tab has the success chance table (unneeded since I now have the formula) and the scratch area for tracking exp gains.

Let me know if this helps or is confusing!

I was wondering has any one else gotten stuck I'm at 86 in cooking and i fail every desynth that is not 100% and am getting sick of seeing and 79% chance when really there is a 0% or maybe .000000000000000000000000000000000000000000000000000000000000000000000000000001% chance of success. i fear it is my extremely bad luck and should just give up.
