Tanning and peeling: you can also make money, but it is generally a stealth profession. It's convenient to go to the cave to peel off monsters shot down by others.
Engineering forging: stamping skills are expensive and useless. Drawings are generally plate armour.
Tailor FM: You can also make clothes to help ring FM, but the equipment can be moved. Moreover, it is necessary to make a dress, and the promotion is not big ... the FM ring can't be improved much, so it's boring. Of course you can make money.
Jewelry: Cutting stones to make money can also have special stones, but the overall improvement is not great.
Alchemy: making a general potion to make money. On the one hand, you can eat the unique potion of gold refining.
Generally speaking, if you want to make money, you must choose: alchemy FM (jewelry)
You should improve yourself: tailor-made jewelry (some drawings are jewelry processing) FM (ring FM)
For future consideration
If you make money, all three will do, because 80 has no imprint, and alchemy will definitely have benefits, but the competition is also fierce, FM and jewelry are necessary, and it is impossible without good hardware at first.
If you want to improve yourself, you can choose jewelry FM, because the equipment can still be brought, but the stone unique to jewelry and the specific part of FM are not, and the tailor can let go. Of course, if you want to achieve the ultimate, you can consider FM and tailor. After all, it is more convenient for these two to practice together ~
