Desynthesis Endgame Guide

[Syrinath]

Do unique(blue) items give more desynth exp than whites? I seem to be getting more from ironworks items for armorer (i120) then i133 titanium armor. While the ironworks is easier to desynth.
Ill do some logging: (beginning from memory)

dskill prob. item gain
~109 ~67 ironworks gaunt. of fend. 2.37
~111 ~45 hq titanium mask of strik. 0.91
bacon used,
~112 ~74 ironworks magitek shield 2.05
~114 ~76 ironwork sabaton 1.72
116.44 55.25 titanium kite shield 1.09
117.53 56.95 titanium kite shield 1.32
118.85 85.85 mythrite scutum (i115) 0.94
119.79 87.55 ironworks magitek shield 1.61 ironworks giving more exp at higher success rate?
121.4 92.65 ironworks magitek shield 1.14
122.54 100 mythrite tassets of fending 0.59 i115 is decaying in exp gain
123.13 100 mythrite tassets of fending 0.59
123.72 99.45 ironworks magitek shield 0.90 ironworks still giving more exp
124.62 79.05 titanium plate belt of fending 0.59 easier than kiteshield, so less exp
125.21 70.55 titanium kite shield 0.93 it finally gives more exp than ironworks, although ironworks is already decaying
126.14 72.25 titanium kite shield 0.79
126.93 82.45 titanium plate belt of fending 0.69
127.62 84.15 titanium plate belt of fending 0.87
128.49 85.85 titanium plate belt of fending 0.94
129.43 87.55 titanium plate belt of fending 0.80

Comments on what it looks like to me:

Hmm... there was that brief section where the titanium shield was giving >1 exp, and looking at my earlier entries, mythrite had that as well.
To me it looks like exp is increasing up until a certain number of levels before the item (peaks above 1), where it starts decreasing to below 1, and then levels out for a bit.
Mythrite had exp >1 and up to 1.37 at about 101.89 dlevel. It then decreased a bit from the peak.
Titanium had exp >1 at 1.32 at 117.53 dlevel
The ilevel difference is 18 which is basically the dlevel gap, so it seems to be a set number of levels lower where it peaks.

And as long as ironworks was less than ~100% success rate, and so did not have much decrease in exp given, it provided better exp for a given success rate.
This data only shows ironworks starting at 2.37 exp, and decreasing from there, but the previous set showed noct with an increase up to 2.95 and a decrease from there.
