This is a Lv22 [Wind Crystal] Desynthesis. I have no goldsmithing skill, and have Clothcraft59; was able to HQ most of the coats (3/5) during my try. It made some profit.
I also tried the [Lightning Crystal] Desynthesis. Tried twice, failed twice. Forgot about it.
Wind crystals make linen cloth, and lightning crystals make linen thread anyway... The Wind desynthesis is better.
I have 23 Cloth and it was allowing me to use a lightning crystal and try desynth on these. I failed it 3-4 times. I had to try - was running out of room!
I believe that you may need some skill in Goldsmithing. I have 51 Goldsmithing and only 20 in Clothcraft and I can HQ these coats about 65% of the time using wind crystals.
Many items in clothcraft, such as robes and cuffs, require some skill in Goldsmithing. Perhaps the Tonberry coats have a Goldsmithing element that is used in desything. Since the results are linen cloths, this may make sense considering that many of the above stated items require linen cloth to create as well.
Does anyone know the desynthesis with these when using Wind or Lightning Crystals? If so, please tell us and the level cap for them if you also happen to know that as well. And tell us the amount you received as well. We need to put more info into Allakhazam.
I know these coats can be broken down (lightning crystal) into linen thread, just like antican robes break down into cotton thread. I am not sure on the skill level though
