At about level 10 after Gozen joins your group and
you defeat the demon wolf, go to the crafting
store in the Jade City. Buy Hardbone Hilts and
Steel Blades and make some Sabers. You do not need
the recipe, as the ingredients are as mentioned.
Combine the Hardbone Hilts (150 gold) with the
Steel Blades (300 gold). The created Saber can be
sold for 1,000 gold, giving your a 550 gold
profit. If you do it on a large scale, you can
make a large amount of gold quickly. Save the game
often. If it fails to craft, you will only lose
the cheaper Hardbone Hilt. Also, once you make one
Saber, the recipe is automatically added and do
not have to select the ingredients constantly.
