Desynthesis Endgame Guide

BSM:

- dSkill: 64.56
- Item: (r#) Cobalt Baselards
- Success: 100.% (no buffs)
- Exp: .3
- Items: up to 2x BC1, fire shard, earth shard, up to 2x cobalt ingot, CD2, rosewood lumber

I propose these as an alternative to the Horned Hatchet. It is relatively simple in terms of materials, that is to say, just two, compared to the hatchet's five, which means that if you desynth it back into its constituents, it's more easily recrafted and redesynthed. AFAIK, the difficulty is the same, and the exp gained is at least equal to the hatchet.

Hi everyone. Sorry the guide is now pretty much worthless with all the new changes. Heck, I was getting 0.01 exp from desynthing random low level stuff on my 170 dSkill GSM, which really surprised me! The changes appear to make it possible to desynth stuff much, much higher level than before, but with a low chance. Random dungeon gear from the 53-57 dungeons was giving my dSkill 96 BSM a 6-10% chance, and when I once succeeded, I gained well over a point of dSkill for it. The gaps are now closed and leveling desynth is much, much easier. I'm going to have to rewrite the guide practically from scratch to update it, and with my vastly decreased time in game, I don't really have the time to do that quickly. Sorry, but it could be a while before this guide is back to where it was. I'll post here when I have more info. If people post info like Keaira did (which is very helpful, thanks!), it really does help. Otherwise, I'll wait until I have time to gather the data myself.

Thanks all.

On second thought, I take back saying to wait until 165 or 170 for Valerian gear. As long as you have at least a HQ Tinker's Calm, it should always be fine to desynthesize items whose ilvl is equal to your dlvl as of 3.1.

From what I can tell, that depends on what level you're talking about. I'm still gathering the data, but it seems like the following might be true. I need more datapoints to verify, so please let me know if any of this is wrong:

The old formula for success rate was:

Success Rate Formula:
Let {dScore} = dSkill + 30 - rlvl
Let {W} = 19 - min( ceiling( rlvl/5 ), 9)
IF  0 <= {dScore} <= 20: Success Rate = ({W} * 0.15 * ({dScore}))
IF 20 <= {dScore} <= 30: Success Rate = ({W} * 0.20 * ({dScore}-20)) + 3*{W}
IF 30 <= {dScore} <= 40: Success Rate = ({W} * 0.20 * ({dScore}-30)) + 5*{W}
IF 40 <= {dScore} <= 60: Success Rate = ({W} * 0.15 * ({dScore}-40)) + 7*{W}

The new formula appears to be:

Success Rate Formula:
Let {dScore} = dSkill + 50 - rlvl
Let {W} = 19 - min( ceiling( rlvl/20 ), 9)
IF 0 <= {dScore} <= 50: Success Rate = ({W} * 0.10 * ({dScore}))
IF 50 <= {dScore} <= 60: Success Rate = ({W} * 0.20 * ({dScore}-50)) + 5*{W}
IF 60 <= {dScore} <= 80: Success Rate = ({W} * 0.15 * ({dScore}-60)) + 7*{W}

Or, if you want a single, unified formula:
min((19-min(ceiling(rlvl/20),9))*((0.15*max(min(dSkill-rlvl-10,20),0))+(0.20*max(min(dSkill-rlvl,10),0))+(0.10*max(min(dSkill-rlvl+50,50),0))),100)

The key differences are highlighted. To put it more simply:

It used to be that items rlvl 1-40 had a higher success rate than later items, with the bonus dropping every 5 rlvls until rlvl 41. The bonus was 80% at the start, dropping by 10% every increment. Now, it seems like the same exact bonus exists, but it drops every 20 rlvls instead of every 5, stopping at rlvl 161. So, on top of the other new bonus, when desynthing an item that's r100, you have a 40% bonus compared to before. At dSkill 100, instead of having a 50% chance to desynth an r100 item, you have a 70% chance. At dSkill 110, instead of having a 70% chance, you have a 98% chance.

In addition, the old chance of successfully desynthing an item 10-30 rlvls above your skill level is now the chance for an item 20-40 rlvls above. So, if you're desynthing an r180 item and your skill was 160 before, your chance would have been 15%. Now, if your skill is 150, your chance to desynth an r180 item should also be 15%. Before, your chance at dSkill 150 would have been exactly 0%, but now the point where it's exactly 0% should be dSkill 130. From the point where it's 0%, every point of dSkill increases your chance by 1% until 50%. In the past, each point would give 1.5% until 30%, and then 2% until 50%, but now it appears to be a flat 1% that starts much, much earlier. From the 50% point, just like before, each point gives you 2.0% until 70%, and then like before, each point gives 1.5% until 100%.

The upshot of all this is that your chance to desynth an r170-r180 item with equal or higher dSkill has not changed. However, you now have a sizable boost to desynthing items higher than your skill, and you have a sizable boost to all desynths of items r160 and below.

Here's a quick chart of where each common rlvl from 55 onward should now hit 100%:

• rlvl 1-20: dSkill ({rlvl}+3)
• rlvl 20-41: dSkill ({rlvl}+5)
• rlvl 41-50: dSkill ({rlvl}+7)
• rlvl 55: dSkill 62
• rlvl 70: dSkill 85
• rlvl 90: dSkill 101
• rlvl 110: dSkill 125
• rlvl 115: dSkill 130
• rlvl 120: dSkill 135
• rlvl 125: dSkill 144
• rlvl 130: dSkill 149
• rlvl 133: dSkill 152
• rlvl 136: dSkill 155
• rlvl 139: dSkill 158
• rlvl 142: dSkill 166
• rlvl 145: dSkill 169
• rlvl 148: dSkill 172
• rlvl 150: dSkill 174
• rlvl 160: dSkill 184 <-- items r160 and above cannot be 100% desynthed yet without bonuses
• rlvl 170: dSkill 200
• rlvl 180: dSkill 210
• rlvl 185: dSkill 215
• rlvl 190: dSkill 220
• rlvl 200: dSkill 230
• rlvl 210: dSkill 240

At max skill (180), without bonuses, these should be your new desynth chances:

• r150 and below: 100%
• r160: 93.5%
• r170: 70%
• r180: 50%
• r185: 45%
• r190: 40%
• r200: 30%
• r210: 20%

I don't have exp data yet. I'll have to look into that later. Also, please let me know if anything above here is incorrect.

[kog985]

I forgot to take note the data, but for my BSM with currently stays at 88.16 dskill, back when pre-nerf, the success rate for Artisan's mainhand will stands around 60% right? Now they gave 100% when i have lower 88.16 dskill (around 83), and each desyn will gave around 0.30 to 1.00 dskill points.

And also with my current BSM dskill level, the success rate for desyn Mythrite mainhands are 21.60%. Same goes for my LTW with 86.24 dskill level and get 20.80% success rate for Ironworks equipment that haven't upgrade to Augmented. (Dodore equipments will give 100% success rate when desyn)

My GSM has 72.41 dskill at the moment, and when desyn Garuda/Titan/Ifrit accessroesi, it gave around 40% success rate and 1.50 to 2.00 dskill points if success desyn. (2.60% success rate for Ironworks equipments)

I am really sorry for not taking the data note, I will do it the next time. And I hope these informations will help.

[Nyalia]

I hope these informations will help.

Artisan's mainhands are r70, so your old chance with dSkill 88 would have been 82%. Now, an r70 item hits 100% at dSkill 79 (if my maths are right).

The mythrite main hands are different based on which one you're talking about. Could you please let me know which one? If, with 88.16 dSkill, your chance to desynth an r115, r120, or 125 item is 21.60%, my math is definitely off, but it's hard to know what parts is off from that.

86.24 gives you a 20.80% chance on an r120 item? That means my math is definitely off. Honestly, I kinda guessed on some of the formula due to having too few datapoints.

39% at -20, 20.80% at -34, 18.20/14 = 1.3/13 = 0.1. Hmm. Interesting. It seems like it doesn't go back up to a factor of 0.15 after 20 points, but stays at 0.1. I didn't expect that, it's far more generous than I'm used to from SE.

Ooh, you gave me another data point to confirm it:
20.80% at -34, 2.60% at -48, 18.20/14=1.3/13=0.1. Still 0.1 all the way down at -48.

All of this means the 0% point is -50, not -40. Wow. Okay.

And now to reapply it to the mythrite thing:
21.6/(14,13,12,11) = (X,X,1.8,X), so {W}=12. If you get 1.2% per dSkill point, then you're 18 points above the 0 mark. This is weird. If the item is r120, {W} should be 13, not 12, but if your dSkill is 88.16, then that's looking like a {W}=12 r120 item, which I don't understand. It doesn't fit the math. If your dSkill was actually 93, and the item was an r125 item, then everything would make sense, but if you're saying that with 88 you have a 21.6% chance on an r120 item, I'm just confused.

Maybe if you post the specific item you're using, or I had another datapoint, I could make sense of it? If your dSkill is really 88, then I wonder if it's ilvl and not rlvl that determines the {W}... or if HW items just have a lower bonus?


Thanks for all the data!!

Sorry for the lack of information. The Mythrite I was talking about is Mythrite Hatchet, BTN mainhand, Lv 52, ilvl 85.

EDIT: I got the picture here.

[kog985]

This is my current desyn level. I don't really know much about the items, i just try anything that i have in my inventory, but i would love to contribute to the data. So if you guys want to test out any specific items, just give me a word.

Okay! Let's see, ARM 19.15, +51 would be r70, perfect. Take an r70 ARM desynthable item with a materia slot (either a 50** recipe like Darksteel Tassets, or a Warwolf item from PvP like a Warwolf Belt of Fending) and see what your desynth chance would be at 19 skill. It should be 0. Meld a piece of materia to it and check again. I would expect your chance to be either be 6% (negative factor: 0.10) or 3.75% (negative factor: 0.25).

EDIT: Also, if you did the same with a GSM item that was r125, like a Mythrite Bracelet of Fending, and checked both 1 and 2 materia melds at dSkill 72, that would also be really helpful. That's -53 with a bonus of 20%, so I'm expecting either 2.40% (0.1) or 0% (0.25) for one meld, and 8.40% (0.1) or 3.00% (0.25) for two melds.
