It costs a lot of money not to learn to mine jewelry. Especially now the trumpet is equipped with FB, and few people dig low-grade mines, such as mithril, real silver and the most expensive mine now. Mining by yourself can save a lot of money. If you don't learn to collect herbs, alchemy is the same as the early stage of jewelry. At the same time, it is also time-saving to buy materials at auction or collect them yourself.
After practicing, I feel that these two majors make the fastest money, and medicines and gems are consumables.
Illustration in jewelry: Statue-sea albatross (5 seconds back 18 blue, 900 blue back) is good in a protracted war.
