Let me put it into perspective :
100-102 = 1.7M/12 synths
~8M to 102 (Elemental rings)
Recycle your rings. Invest in Desynthesis Moghancement and a GS ring.
~~~~~~~~~~~~~~~
102 - 104 gold=~1.7M / 12 SYNTHs (Silver Cassandra)
Overall Cost for me: ~17 Mil.
~~~~~~~~~~~~~~~
105 gold is 1.3 mil/synth 15.6M x's 2 (sets of 12 synths if your lucky) You can also do hexed gear at this point, but save those Ormolu for 110.
= ~31 Mil (Ugol Hauberk)
~~~~~~~~~~~~~~~~
110 is 4 mil a synth
and 4Mil/synth x 12 x (5 whole levels at 2 stacks/ level) 10
= $480 Mil to 110 Goldsmith (Hexed hauberk)
add all that up and you come up with
approx 300~480 Million gil for 110 GS depending more on luck for the lesser.
so the hexed stuff will range 3~5 mil for NQ just to break even.
