Ethnic Selection Strategies of Nostalgic Costume Soldiers
First aid, cooking, fishing, everyone can learn! You must learn first aid. If you fish, you don't have to practice in a hurry. If you want to fish, you can fish. The fish you catch can be used for cooking. It's very interesting! As for the two professional skills, it's actually no big deal. Just pay attention to one thing. If you study forging, engineering and gems, you'd better study mining. If you are an alchemist, you'd better learn to collect herbs! The rest really didn't work.

There is no specific requirement for this. Just do what you like. My soldiers learned forging and alchemy. DK is enchantment+jewelry, mage is tailor+enchantment, virtue is mining+enchantment, warlock is herb+thief is engineering+mining, priest is more funny, peeling+tanning, in order to achieve that professional achievement, just play around.
