I do semi-AFK processing on my Valkyrie with craftsman clothes and processing stones while I am doing other things, but I check in here and there to deposit old materials and collect new materials to process. I am Master 11 Processing at the moment and can pull in a decent income selling resources like Steel, Bronze, Brass, some Plywoods, and some Planks. I also use other ingots and plywoods to upgrade and sell alchemy stones of protection and destruction. There are certain materials I will also use at workshops to produce high-quality furniture which I then sell on the marketplace.
I believe the only reasons these work for me are:
- I have over 1800LT capacity on my Valkyrie with the fairy skill Feathery Steps V (I am unencumbered up to 125% LT)
- I have enough mastery currently to mass produce 35 stacks at a time
- I ensure my Valkyrie is not idle for more than a brief moment
- I have a 350 CP worker node empire and worker workshop empire that allows me to gather materials instead of buying them and produce items like alchemy stones and furniture that sells on the marketplace regularly
With higher mastery I could make my AFK processing more lucrative, but that’s where I currently sit after about 7 months of playing BDO sincerely (not seriously). This is purely anecdotal and should be taken with a grain of salt.
If you are looking for ways to rapidly increase your Processing Level, materials like Flax, Cotton, and Fleece give a lot of Processing EXP. These are also lightweight and can be processed in bulk overnight with a decent LT capacity. If you choose this path, I would recommend cooking foods that increase your Life EXP such as Assorted Side Dishes (+5%), Sute Tea (+8%), or Whale Meat Salad (+10%). Longer lasting higher quality versions can be made with high enough cooking skill. A nice set of +3 Silver Craftsman Clothes and Books of Life might also be a good investment.
I hope you can find some use of my ramblings and, if you have any questions, do not hesitate to ask.
