Desynthesis Guide

General Information

The recipe level (rlvl) of an item is all that matters for desynth difficulty and dSkill gained, not the item level. For crafted items, this is the level of the recipe, but even non-crafted items appear to have a hidden "recipe level." For endgame dungeon drops, these are the same as the ilvl. For non-crafted vanity gear, it's fairly arbitrary (Blue Summer Maro, for instance, is r55).

The formula for desynthesis success rate is:

{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)

With items rlvl 41 or higher success rate equals:

  • dSkill = rlvl - 30 or less: 0%
  • dSkill = rlvl - 25: 7.5%
  • dSkill = rlvl - 20: 15%
  • dSkill = rlvl - 15: 22.5%
  • dSkill = rlvl - 10: 30%
  • dSkill = rlvl - 5: 40%
  • dSkill = rlvl: 50%
  • dSkill = rlvl + 5: 60%
  • dSkill = rlvl + 10: 70%
  • dSkill = rlvl + 15: 77.5%
  • dSkill = rlvl + 20: 85%
  • dSkill = rlvl + 25: 92.5%
  • dSkill = rlvl + 30 or more: 100%

Each dSkill point increases success rate by 1.5% til the success rate is 30%. Then each point increases 2% til 70% success rate. Then it becomes 1.5% per point again.

Each materia melded to an item increases the chance of successfully desynthesizing that item by 5%.

Patch 2.4 introduced Careful Desynthesis. Every point of Careful Desynthesis increases your desynth success rates by a flat 2.5%. Currently, as of patch 2.5, there are only two items in the game that provide Careful Desynthesis: Bacon Broth (a meal, 4-star CUL) and Tinker's Calm (a medicine, 4-star ALC). NQ Bacon Broth provides Careful Desynthesis +1 (HQ Bacon Broth provides +2) and lasts 30 minutes. NQ Tinker's Calm provides Careful Desynthesis +3 (HQ Tinker's Calm provides +4) and lasts 10 minutes. They both stack for a total of +6, which translates into a +15% desynth success rate.

In a future patch, equipment that increases desynthing chances will be introduced.

High Quality items do not have any better chances of giving demimateria or HQ materials. However, if you're melding materia to an item to increase desynth chances, it's worth noting that HQ items are easier to overmeld materia to (~12-20% boost).

You can only get one type of non-crystal item back from desynthing, but you can get multiple of these items, up to a maximum of the number it takes to craft it. If an item requires 3x Darksteel Nuggets but nothing else to craft it, you can get back 1, 2, or 3 Darksteel Nuggets from desynthing it. If instead it takes 1x Darksteel Nugget, 1x Rose Gold Nugget, and 1x Spruce Plywood, you can only ever get a single one of these back, and only 1x of it. This means that items with fewer types of materials are generally cheaper to use when leveling than items with many types of materials.

When you get an item back from desynthing that can be High Quality, it appears to have a 20% chance of being HQ and an 80% chance of being NQ (highly estimated, relatively small sample size of ~500 desynths).

The Zodiac Weapon quest requires you to obtain eight different crafted items. Each of these items requires one item only obtainable via desynth (along with other things). The items you need to desynth are r55 (1.5% chance at dSkill 26, 30% at 45, 50% at 55, 70% at 65, and 100% at 85) and can be bought from a merchant in the Silver Bazaar in Western Thanalan. There is one for each desynth class. The expected yield for the materials is about 0.2 per desynth. The materials (and the finished crafted items) are buyable/sellable on the Market Board. The crafted items can also be desynthed and are r90.

Times you can desynth: while moving, in dungeons/trials/raids/guildhests, while in queue (before the duty pops), while in PvP, while bound, and in combat (with GCD cooled down - Try it while tanking after establishing aggro. Your party will love you!). The last one is not recommended.

Times you cannot desynth: while zoning (you also can't zone while desynthing), during cutscenes, after a queue pops but before entering the instance, while mounted (the saddest thing!), while sitting (or dozing on a bed), while crafting, while gathering, with any interaction window open (buy/sell interface, retainer interface, etc), while teleporting, while in the inn rooms, while using a combat skill, while your GCD is cooling down, while under stun/sleep/petrification/hysteria/fetters (have not yet tested Brainjack), and while dead.

Note that you cannot block or parry while desynthing.

Losing Desynthesis Skill Points

With patch 2.5, you will no longer lose desynthesis skill points, ever, while under the combined cap of 350.00.

If, after succeeding on any desynthesis (and after adding in any dSkill gained, if any), you are over the 350.00 point combined dSkill cap, you will lose as many points as you are over the cap in a random non-locked (see below) desynth class. Only classes that you have at least at 1.01 can be chosen, and classes can't go below 1.00. These points are lost even if you gained no dSkill points from the desynth, and even if your current class is at the max 110.00.

Locking desynth classes: There is a trick to controlling which class you lose the points in whenever you lose points. Essentially, looking back at the last 3 desynths where you succeeded (even if you gained no experience) and the one you just succeeded with, none of the desynth classes used can lose experience. So, if you desynthed with ARM, then LTW, then CRP, then CRP, and then you desynthed with BSM and the BSM desynth triggered a lose of dSkill, that loss can't come from BSM, LTW, or CRP (but could come from any other, including ARM).

At the moment, this can be exploited to raise your combined desynth experience past the 350.00 cap by locking in place all of the classes that you have above 1.00 (possible with up to 4). But, be warned - the moment you mess up your desynth "rotation," you will go back down to 350.00 instantly. Maintaining a constant desynth rotation is an expensive and annoying price to pay for exceeding the 350.00 point cap, and it's likely a bug that will be corrected in the future anyway.

Analysis

SE keeps rotating which the "best" desynth classes are for making money and for advancing crafts. Right now, in 2.45, LTW is the best for FC3s, and BSM is the best for MCDs. In 2.38 and earlier, GSM was the best for both. WVR and ARM also became far more useful with 2.45 - ARM can desynth the vast majority of Allagan items, and WVR is good for getting FC3s (though not as profitable as LTW). GSM is still decent for MCDs and FC3s, but no longer the best. If you have a huge stack of Rowena's Tokens from the weekly repeatable, ARM desynth is your friend (try the shields). CRP and ALC are probably the "worst" desynth classes of the moment, but that could very easily change next patch. In 2.5, ALC may be bumped up a bit if desynthing Aetherial Wheels is useful, and CRP may go up as well if a hotfix makes the new Artisan gear desynthable. As always, CUL doesn't get any demimateria at all, just swimsuits, so it's a terrible choice if you want demimateria (but great choice if you want swimsuits).

Leveling and Endgame Guide for each Class

Please keep in mind that because prices are constantly fluctuating, it is hard to pinpoint the absolute cheapest way to level desynth at any given moment. To that end, in most cases, I try to point out multiple items at each level, one of which should be the cheapest. Please compare their costs on your server to determine what's actually cheapest!

Remember that you will continue to gain desynth experience on every success up until your skill is 25 levels higher than the item. Then, you have a chance to gain experience up until 30 levels higher than the item, at which point you stop gaining experience. When it's best to stop using one item and swap to a new item is hard to determine, so I've often left that choice up to you by overlapping the suggestions. Generally speaking, the more sacrifices you leave for RNGesus, the sooner you should swap. The more you fear the wrath of RNGesus, the longer you should continue with a given item before swapping to the next.

Goldsmith

Arguably the easiest class to level and one of the best to have for getting demimateria. Has multiple good avenues of getting Fieldcraft III (token turn-in [Artisan's Spectacles], crafted [Rimless Glasses, Carbuncle Chronometer]), Battlecraft III (PvP [Warwolf acccessories], dungeons [Darklight accessories, Hero's accessories], crafted [Gold Spectacles]), and Mastercraft Demimateria (token turn-in [Artisan's Spectacles, Artisan's Needle]). It can also get Inferno and Vortex Demimateria. With 2.4, GSM can also obtain Crags Demimateria by desynthing Titan Extreme drops.

Endgame Items

Blacksmith

At the moment, BSM likely has the best way of getting Mastercraft Demimateria. BSM has the advantage of being able to desynth a number of Primal (non-Titan) weapons, Summoning Bells (wonderful at 100 skill for getting Fieldcraft IIIs), and Artisan's/Forager's tools (great way of getting Mastercraft Demimateria). Unfortunately, BSM is not a good way to get Battlecraft IIIs unless you love farming HM Primals.

Endgame Items

Carpenter

CRP has a fairly easy and cheap way to get Fieldcraft IIIs via an i70 furniture desynth (Straight Stepping Stumps), but it is no longer that great compared to LTW. It also has a few options for i90 furniture too. However, CRP is not a great class for getting Battlecraft IIIs (unless you farm Garuda/Mog as a BRD). CRP is surprisingly cheap to level early on (1-40). At the moment (as of 2.45), I find CRP to be one of the two weakest desynth classes (but that could easily change with the next patch).

Endgame Items

Weaver

Very cheap to level to level in general. Most of the mats for the early levels can be bought from vendors. Has a good option for Fieldcraft IIIs (Bridesmaid's Tights / Best Man's Slacks), and can get Battlecraft IIIs from dungeon loot (and crafted items, but I think they're still too expensive to be worth it). Can get Allagan materials from desynthing Allagan armor. Can also get Mastercrafts with a substantial time investment (Forager's Hats). With 2.5, Ribbons became desynthable, so WVR may be able to get Demimog Demimateria, but cannot get any other Primal demimateria.

Leveling Guide

Endgame Items

Leatherworker

LTW is very useful in 2.4. It has the cheapest way by far to get Fieldcraft Demimateria IIIs, and it (along with WVR and ARM) can desynth Allagan armor to get Allagan crafting materials. These crafting materials can also be obtained by running Coil, but in addition to getting the base Allagan materials, you can get the 4* materials that the Allagan materials are used to make. You can also get a large amount of Hard Hippogryph Leather very cheaply, and you can desynth Myth gear for various materials and Battlecraft Demimateria IIIs. As before though, it has no way to get Primal demimateria (except Demimog) or Mastercraft Demimateria.

(note to self: do maths to check double-melded Saurian Gloves of Casting for 100-110 feasibility)

Endgame Items

Armorer

Though ARM has one of the cheapest ways to get Battlecraft IIIs through crafted gear, it doesn't come out ahead compared to the MB value (on my server at least) and is not as good as using dungeon drops. That said, it does have the cheapest way to get Battlecraft IIIs via PvP. It is one of the worst classes in the game for getting Fieldcraft IIIs (sadly, 2.4 did not introduce Bridesmaid's Platemail, or Bridesmaid's Gauntlets of Fending). It can get Allagan materials from desynthing Allagan armor, but mostly only Allagan Wootz Nuggets which are the least valuable (however, there are far, far more ARM-desynthable Allagan armor pieces than WVR and LTW combined). It does have a decent ability to get Mastercraft Demimateria (via desynthing Artisan's Frypans). Like the other armor-making classes, ARM cannot get Primal demimateria.

ALC desynth is the only way to get Demimateria of Crags, and it has a decent ability to get the other Primal Materia (especially if you main SCH or SMN). It is, however, arguably the worst for getting Fieldcraft Demimateria IIIs, as it has no i90 furniture nor i90 equipment. It does have the cheapest way to get Battlecraft Demimateria IIs, but they're of limited usefulness. I believe that leveling ALC would be one of the more annoying classes due to the number of recipes that require intermediate equipment. At the moment (as of 2.45), I find ALC to be one of the two weakest desynth classes (but that could easily change with the next patch).

Leveling Guide

[* I recommend you get a team of all friends/FC mates together to farm Titan HM for a while. Have everyone else who isn't leveling ALC desynth pass on the loot, and divvy up the Demimateria of Crags you get from them. Alternatively, see this post for information on Mog Farming that could also apply to Titan Farming.]

Endgame Items

Culinarian

The only items that CUL can desynth are fish. At endgame, CUL can desynth Big Fishing to get the twelve swimwear-related items (Sea Breeze Pareo, Sea Breeze Summer Halter, South Seas Talisman, Blue Summer Maro, Waterproof Cotton, Coronal Summer Halter, Ti Leaf Lei, Red Summer Pareo, Red Summer Maro, Summer Sandals, Gold Roselle Capeline, and Oschon Roselle Capeline). Unfortunately, CUL seems to be a one-trick pony, and that trick is swimsuits.

Note that fish can never desynth into any Demimateria except Clear Demimateria, which exists only to be sold to vendors for gil. Fish can desynth into shards and crystals (but never clusters). All fish can give water shards/crystals. Sand fish can also give earth shards/crystals, sky fish can also give wind crystals, lightning-related fish (such as the Judgeray) can also give lightning crystals, and fiery fish (Bronze Lake Trout and Joan of Trout) can also give fire shards/crystals. No fish yet desynths into ice shards/crystals.

A trick to getting a specific fish faster from a fishing hole is to look at how your rod moves when you hook a fish. There are three types of tugs, as far as I can see. A very light tug where your rod barely moves, a moderately strong tug where the end of your rod bends noticeably (about 45 degrees) and makes a stretching noise, and a massive tug that bends your rod over 90 degrees and makes a hollow, wooden noise (and your controller will go crazy, even if you're in another window.

The same fish always triggers the same kind of tug, but there's only a weak correlation between tug strength and rlvl for the first two tug types. That last, massive tug type means you definitely have a Big Fish on your line (though a few Big Fish are only moderate tugs). If you hook a fish you don't want, wait for the fish to go away and cast again (or cancel and cast again). This burns through bait quickly, but if you're using lures, you only go through ~5 an hour or so.

This trick more than doubled my Silver Sovereign fishing rate. It also vastly increased my Octomammoth catch rate since only two fish pulled up by Pill Bugs are moderate tugs, and if my mooch off Harbor Herring doesn't trigger a massive tug, it's not an Octomammoth. I highly recommend trying this.

[* The indicated fish are untradable]

[** Catch rate indeterminate due to weather and/or time restrictions skewing available data]

(Starting at 35 skill (or earlier), I highly recommend grinding on Fullmoon Sardines at South Umbra Isles at night with an Iron Jig as bait. You will have a 100% chance to catch them, and if you get an HQ fish, you can Mooch it to either an i45 fish or an i55 fish. Once you have a fair number of the i55 fish and/or you have stopped getting CUL experience from the NQ Fullmoon Sardines, finish with the sardines and go ahead and break all the Nautiluses you Mooched up. Once they're all broken, if your skill is ~55+, go ahead and break the Coelacanths you also obtained through Mooching. This should be able to get you from 35 to 60 pretty fast.)

Cheap Sources of Demimateria

In this section, I'll try to list the theoretically cheapest desynths for each desynth class to get each type of Demimateria. Please note that these vary wildly depending on server prices and I'm using data from Faerie to make these calculations.

Following each item name will be [i#|#s]. The first number tells the recipe level of the item. The second number tells how many materia slots the item has. Together, these let you know the item's chance of successful desynth. I will only list #s for i70+ items.

Included below are the expected values of the gil per demimateria calculation for some of the items at 50, 75, and 100 skill. The prices are being made using current data from Faerie, and are assuming you get the item's materials from the MB, a vendor, or from crafting it yourself (whichever is cheapest) and you make the item yourself. Sometimes, melding materia to the item will decrease the expected cost per demimateria yield more than it increases the cost of the desynth. In these cases, the number of melds will be listed. For the price of the melds, I am using 650 gil per meld attempt (500 is the price of the cheapest garbage materia on Faerie, and 150 is the current price of Carbonized Matter).

[ Warning: Section still in progress; still working out the yields for Demimateria IIIs (getting very high variance in results); also, need to do research on Demimateria Is before definitively saying what works (both minimum ilvl and whether ilvl affects chances are unknown, but data strongly suggests that ilvl does matter) ]

Fieldcraft Demimateria I

Used to get the new crafting books (5x each), for crafting DoL/DoH accessories (10x), glamour items (5x), and furniture (2x)

[To obtain: Desynth rlvl 25?-49 DoL/DoH gear, furniture, and equipment parts (1x from r26?-r35?, 2x from r36?-r49?)]

Fieldcraft Demimateria II

Used for crafting Crescent Moon equipment (5x each) and new furniture (2-3x)

[To obtain: Desynth rlvl 50?-55 DoL/DoH gear, furniture, and equipment parts (1-2x from r50?-r55)]

[r55 items appear to have a 10% chance of dropping 1 of these, and a 10% chance of dropping 2, giving an expected yield of 0.3 per successful desynth]

Fieldcraft Demimateria III

Used to get the new crafting tools (10x each) and for crafting new furniture (1-3x)

[To obtain: Desynth rlvl 70+ DoL/DoH gear, furniture, and equipment parts (1x from r70+ (Yield: ~0.2), 1-2x from r90+ (Yield: ~0.2)]

Battlecraft Demimateria I

Used to get the new crafting books (5x each) and for crafting the i90 accessories (5x)

[To obtain: Desynth rlvl 25?-49 DoW/DoM gear (1x from ?-?, 2x from ?-r49]

Battlecraft Demimateria II

Used for crafting augmented i90 crafted armor (10x) and i90 accessories (2x)

[To obtain: Desynth rlvl 50?-55 DoW/DoM gear] (1-2x from r50-i55)

Battlecraft Demimateria III

Used for crafting upgraded Primal weapons (10x) and augmented i90 crafted armor (1x)

[To obtain: Desynth rlvl 70+ DoW/DoM gear (1x from r70+ (Yield: ~0.2), 1-2x from r90+ (Yield: ~0.2)]

Mastercraft Demimateria

Used for getting the new r75 DoL/DoH tools (3x for each except FSH, which only takes 1x) [To obtain: Desynth Artisan and Forager items (1x from hats, 1-3x from tools)] Prices currently heavily in flux due to new changes! It is unclear what the best desynth class for obtaining MCDs is now, but it's either BSM, GSM, or ARM (most likely BSM). Prices below assume all shards (a significant portion of the costs) are 100 gil each, which they were on my server last I checked (more or less).

You're going to have to do some math here:

  • GSM: Artisan's Needle [r70] - {1-3x} Other: Turn-in (to compare it to BSM options below, use the formula: [8*({silver ingot}+2*{twinthread}+2100)]
  • GSM: Artisan's Spectacles [r70] - {1x} Other: Turn-in (which turn-in is best varies wildly now, but it's likely CRP or LTW)
  • BSM: Artisan's Head Knife [r70] - {1-3x} Other: Turn-in (best if [10*[(2*{hippogryph leather}+2100)] is cheapest, which it should be if no one has bought out all the hippogryph skin on the market yet on your server)
  • BSM: Artisan's Chocobotail Saw [r70] - {1-3x} Other: Turn-in (best if [8*({spruce lumber}+3600)] is cheapest, which it should be once someone has bought out all the hippogryph skin on the market on your server)
  • BSM: Artisan's Raising Hammer / Artisan's Cross-pein Hammer [r70] - {1-3x} Other: Turn-in (best if [10*(2*{darksteel nugget}+2100)] is cheapest)
  • BSM: Artisan's Mallet [r70] - {1-3x} Other: Turn-in (best if [10*(2*{rose gold nugget}+2100)] is cheapest (plot spoiler: it isn't))
  • BSM: Forager's Hatchet/Dolabra [r70] - {1-3x} Other: Time (if you have a 50 MIN and BTN and play ~2 hours a day (the gathering itself only takes a few seconds), you can get 2 (one of each) every 10 days)
  • ARM: Artisan's Frypan [r70] - {1-3x} Other: Turn-in (better than alembic if [20*({dzamael tomato}+{dark vinegar}+2100)] is cheaper)
  • ARM: Artisan's Alembic [r70] - {1-3x} Other: Turn-in (better than frypan if [20*(2*{volcanic rock salt}+2316)] is cheaper)
  • WVR: Forager's Hat [r70] - {1x} Other: Time (if you have a 50 MIN and BTN and play ~2 hours a day, you can get 2 hats every 5 days) (1x)
  • CRP: Forager's Rod [r70] - {1-3x} Other: Time (it takes about 40 hours of constantly fishing to get one of these... horrible source of Mastercraft Demimateria)
  • ALC: No known options available
  • LTW: No known options available
