I can Confirm that Goldsmithing lvl 70 to lvl 92 cost me at least 50 Million gil
Also lvl 92-94 cost me 10 stacks of Platinum ingots and about 2 Million in HQ Gems, roughly about 17 million. I desynth most everything, so I got some of the materials back.
o_o I always here things like in smithing and goldsmithing you use lots of gil to get it real high, but my question is how does it work? As in how do afford it? Is there something you can make to give you enough gil to continue your craft?
