Well, we all know that you can buy dusts to enchant your crafting stuff. Well, here's something that might not be so obvious. Once you've done crafting enough, you can refine 3 materials at once instead of 1, like jute cloth for example. However, you only need 1 dust to enchant 3 items. Just use the 1 dust when refining 3 items, and all 3 will be enchanted.
actually when your skill gets higher you can make 5 at a time, and still use one dust. this does not work on jewls though those always have to be done 1 at a time.
and sorry but this is conman knowledge for anyone that is even semi serious into crafting
