PVP is necessary for mining jewelry. Projects cost money, and jewelry can make money. Jewelry learned to cut any gemstone you want, so don't buy it. Besides, there are a few toys in jewelry, which can also be used as jewelry mounts and jewelry pets. Jewelry is still very profitable. And with the exploitation, almost all raw materials can be obtained through NPC or by themselves. The cost is almost zero. It's just that some jewelry drawings are hard to get, but most of them are easy to get. I am mining+jewelry, herbs+inscription. It feels good. At first, I planned to spend some money on jewelry practice, but finally I found that it didn't cost much to practice jewelry. After mining and mineral processing, unused jewels can be sold. The key jewels are all practiced, and there are jewelers' unique jewels, which are better than other jewels. This is very helpful for PVE.
