Both engineering and jewelry need minerals. Jewelry, engineering and mining are three main majors, and everyone can only study two different majors at the same time. It's not that you have to learn mining to learn jewelry, but that you can be self-sufficient by suggesting another major to learn mining.

It depends on whether you want to have fun with this hunter.

Engineering and jewelry have greatly improved DPS. Jewelry has three high-attribute gems, and the project has a glove that has been enchanted to enhance its attributes. If you want to have fun, mining can only be maintained by buying other people's things, without learning or skill!

If you are a casual player, you can only give up one of engineering and jewelry and learn mining!

In leisure time, the project can make some toys or enchantments to improve the gameplay, and can also make some equipment. Jewelry is a simple gem, and you can also charge some manual fees for cutting gems for others. Your own precious stones can be sold for money. Choose for yourself!

Also, you can practice a trumpet and practice double picking, that is, picking medicine and picking. On the one hand, it can be self-sufficient, on the other hand, it can be used to sell money. But it takes time.
