Desynthesis Endgame Guide

[Nyalia]

Desynthesis works the way it does now to play with the ever-present excess of unwanted gear at max level, but when level 50 is a mere rest stop rather than the final destination where a ton of items gather, I don't think it'd be reasonable to ask people to level a desynthesis skill through 80-110, or even 70-110 for some, at the same rate as now.

I don't think I agree with this. Desynth experience gain doesn't really drop much as you level it, it's fairly consistent all the way based on relative rlvls. With enough careful desynthesis, you can level incredibly fast. The limiting factor, of course, is the materials to level with. If the expansion includes r100 desynthable items that are relatively cheaply obtainable, anyone could level from 80 to 110 super fast. Depending on what you're using, it could take as few as 1.2 successes to level Desynth. That's kinda crazy fast, in MMO terms. It only gets hard near the end due to the lack of desynth fodder of appropriate rlvl. They don't really need to invent new catch-up mechanics, they already exist.

So I need confirmation about this: is it possible to get demimog materias and the other primal demimaterias from the current hard/extreme mode gear or is it an old content thing only?
Im asking because im between wasting a ton of money to get one now before they poof or if i should just wait and make it on my own.

Manikku not sure what you mean with old content, but the demimog demimateria and other primal demimaterias came from the primal battles items desynthesis, maybe is not very explicit on first post.

Demimog Demimateria are definitely obtained by desynthing the i75 Moogle equipment dropped from Thornmarch (Hard) (<-- aka story mode). However, no one has yet confirmed for me whether or not you can get Demimog Demimateria from desynthing the i100 Ribbons from Thornmarch (Extreme). I'm not a WVR desynther, and my wife (who is) doesn't run Ex Primals very often.

Keep in mind that yields are never 100%. You have about a 16% chance (extensive testing has not been conducted) of getting Demimog Demimateria. If you do get some, you may get 1x, 2x, or 3x.

Perfect thats what I wanted to know, thanks very muchlytaru <3

What I mean is that if the catchup items are that high so that you do get a lot of skill, then your success chances would be abysmally low. However, now that I think about it I guess that would be okay because they'd be cheap items anyway. So I probably should have thought that through better, lol.

I consider a success rate of 30% to be totally acceptable. That's the chance of desynthing an item that is 20 rlvls higher than your dSkill if you have Careful Desynthesis +6 (via Tinker's Bacon). An item that much higher than your skill will give ~0.8 dSkill on a success. You can get 5 dSkill levels with, on average, 5/(0.8*0.3) = ~20 attempts. That's not very many attempts. For the next 5, it's 5/(0.7*0.375) = ~19 attempts. Then, 5/(0.6*0.45) = ~18.5 attempts. Then, 5/(0.5*0.55) = ~18 attempts. Then, 5/(0.4*0.65) = 19 attempts. And lastly, 5/(0.3*0.75) = 22 attempts. So, you can get from dSkill 80 to dSkill 110 by attempting to desynth just ~117 items. If they are vendor-purchasable, that's really nothing at all. Back when FC3s were really valuable, I would desynth that many in half an hour. Heck, you might even be able to get that many done in a single Tinker's Calm (10 minutes) if your inventory starts pretty clear. Note: without Tinker's Bacon, it would take 137 attempts instead of 117. To determine if Tinker's Bacon is worth it, consider how much 20 more attempts would cost. Is it more or less than Tinker's Bacon?

No other part of FFXIV is faster than catching up desynth, imo. The later levels get hard, but the built-in catch-up mechanisms are there and seem to me to be working great.

But, again, that's assuming there will be some vanity item that's rlvl 100 and purchasable. I guess we'll see in a few days!

30% is exactly what I was worried about and thought would be considered unacceptably low when you're just passing through level 50 as a new player, but I never worked out the math nor realized that a new player wouldn't be interested in the first place. So you're right; it's not so bad at all. Thanks for doing all the work for me, lol. Nice job.

Also, it was nice to see that I almost 100% accurately predicted how Tomestones would be handled! But...it's not like it was anything surprising. I'm sure you thought the same thing would happen.

I'd rather continue this one. I update the OP regularly, so it's not like people need to slog through all the posts to make comments or ask questions.


So, as stated in the OP, I've created a new spreadsheet to track items obtained via desynth in Heavensward. It'll help me support this guide and hopefully be more informative than the OP as far as what items yield what exactly. If anyone wants to help populate the spreadsheet, let me know.

The spreadsheet (still working on it) is here: https://docs.google.com/spreadsheets...gid=1349593587
