I haven't had a chance to update the OP, but the new best way to get Fieldcraft IIIs is through the two new 2-star glasses added with 2.38. It's so much better than any other method that the value of FC3s has dropped all the way to 250k on my server (from 450k) and is still dropping. All other methods are quickly becoming unprofitable.

At the same time, FC2s have risen in value (to 10k on my server) making FC2s worth farming now. FC2s are needed for one of the glasses.


I'll probably wait until 2.4 to update the OP though, because 2.4 will completely change everything again, I suspect.
