Enchant+tailor can also be a mage, because it is cloth armor, so the tailor can be cloth armor equipment and bonus props. Tailors have many other uses, such as making backpacks, which can be sold later. Because of the tailor, choosing a deputy who doesn't need to accept it by himself is the enchantment, which is simple and useful.
Herbs+alchemy alchemy medicine, the mixture is naturally useful in the later stage, but alchemy can also make many interesting multi-purpose medicines such as underwater breathing medicine. Herbs are used to collect alchemy. Of course, there is another advantage of this major, that is, secondary priests should learn this major (enchanted tailors should also learn it)
Mining+engineering can be said to be the major that produces the most gadgets, some of which are very practical, such as parachutes, and so on. But this is still very tiring to practice.
That's the recommendation, but professional skills have nothing to do with occupation. The factors that affect the choice of major are generally: practicality or making money? Is it for viewing or for use? Will it be convenient to choose this major (for example, it was convenient to choose lettering because it was expensive before)? Wait a minute.
