If you are talking transmutes, then farm stone town. Best. Farming. Area. Ever.
I remember having my crafting so over the top, when I actually liked it. I transmuted stone block to sandstone then sandstone to sunstone. This was prior to ZF release. Once that came out I ported to a wizard that had access to it and did the realm switching game to collect them.
I don't craft much now, I guess I wore it out, it seems like KI was trying to let me know nicely, it's not for me any more.
