What is the best way to get them?
I have tried several methods, and still can't settle on one. I like the first method the best, but it's a problem to do it in large numbers. I can craft them at 99% at rank A so at least I am not wasting materials. The only problems are the sheer volume of materials (9 inv blocks per board, or 77 for 10) and the expense (each board is 15-20k in materials).
The second method is cheap (each board costs 200-500g) but is tedious as hell. I've gotten boards at a 2-4% rate of return.
The third method is good -- I pay 10k per board -- but is also very slow. Very few people sell them, and never more than a few at a time.
The fourth method is slow, and would require a lot of MP10s or MP30 pots for me (Giant with firebolt). On the plus side I would also get XP and MP50 potions, but when I balloon I tend to prefer other rewards (fabric, herbs, and enchant scrolls).
The fifth method would be the best. I farmed about 200-240 of them during the event last year, which I unfortunately sold for 3k each to someone. XD Well, that and the Finest Leathers I sold helped form the foundation of a friendship that has has benefited me as well in the year following. I just hope we get this event again, or another event with production materials as prizes.
So, how do you get them, and why do you choose that method?
