WARNING: Long post.
Just to warn you Gourry, your guide is pretty solid, but I'm gonna be pretty blunt in my post. Hope you don't take offense, that's just how I am.
The adept 80-90 section really depends on server.
Also if you take ANY craft past 60 you will realize just how BAD it is to synthesize armor.
I mean, it takes 36-48 synths for ONE freaking level. Now imagine how long it will take to sell 36-48 pieces of Thick mufflers. (How many lv69+ WAR/DRK/BST are on *your* server?)
Now multiply that by 7 levels.
Thick mufflers are about 30k loss on my server.
Celata's even worse, maybe 50k loss. Each.
I guess much of your guide assumes time isn't as important as gil. I mean, who the hell synths Bastard swords? I mean you can lose 75k in one synth fail. then try making 36 of these and waiting for them to AH. lol. One sells once a week on my server. Sure it might be profit, but who the hell can wait that long? It is my honest opinion that the best route is through NPCable goods, cutting your losses because you WILL make the money back later on. Honest to god truth. However you are still in the 60s so maybe you don't understand how it works.
I am definately not an advocate of Darksteel Nodowa, but in reality, there simply isn't much better.
Darksteel Nodowa (83) --- Earth Crystal + Darksteel Sheet + Silk Thread --- Vendor for 4,000G norg guild
Darksteel Sheet 26,000G + Silk thread 2,000G = 28,000G - 4,000G = 24,000G loss each x 36 - 48 = 864,000G - 1,152,000G loss per level. However, (following some goldsmithing routes) you CAN desynth these. It's not *that* great but it does beat vendoring them. the problem is you need a HQ2 to get the Darksteel ingot back. HQ1 is still silk thread >< In about 12 Nodowas I can get maybe 2 or 3 darksteel (if im lucky) so that beats vendoring them.
83+ I am still keeping to myself until i get there :P
Some other things to add to the guide:
Tama-gahane is 4690G in Norg. They stock 100 each. (8 stacks + 4) at the max. I know because I did a sh*tLOAD of karimata arrowheads. (lol)
Steel Ingots are 3,590G in Mhaura at the lowest.
Nodowas vendor to Norg guilds.
Iron subligars vendor to Bastokan Guild for more than NPC price.
Iron mittens and padded armor also vendor to bastok guild.
War picks vendor to Sandoria guild for 3,510G at the lowest. I've seen almost 5k right after a server maintenance.
Guild prices depend on stock, the more they have the cheaper they will sell AND buy from you. So if you want to make the MOST money, sell right after a maintenance.
Kunai (Jeuno tenshodo) desynths to Steel ingot. Good way to get lizard skins, if you need them.
Mastersmith anvil gives Moghancement: Smithing.
It would also help if you made Guides for cloth, leather, wood, gold, and alchemy (as smithing uses all of these) with a smithing background in mind (changes some things). If you want my help (i already have all of this written up) hit me a line @ email@example.com
