First of all, Im not planning on selling it myself. My seacom says 200mil but I doubt I'll get an serious offer before tomorrow.
Second, if I were selling it wouldnt be less then 100mil.
Third, if you wanna try the 100+ synths go ahead.
Your first problem would be the 3 phaze synth. First the behemoth leather then the sirens macrame and then finally the dalmatica.
This will lead to a high break rate wich means a lot of gil lost.
Then theres acctually finding a crafter to do it. A leathercrafter for the behemoth leather. If he or she wants some sort of payment for the synth thats more gil you lose.
Then you need a clothcrafter wich will prolly want a higher amount of gil for the synth than the leathercrafter. More gil you lose. Then you have the biggest problem of all,
the very limited amount of buyers of the (probably very high amount) NQ dalmaticas you will have. So before you try to march all over the price I set on my wares go do some homework
