Personal recommendation project, this major can largely make up for the embarrassment of thieves in the queue. Pacemaker is something that makes you feel no longer depressed when you are in a team. Rocket boots and limited invincible belts can make you handy on the battlefield. All kinds of explosives can not only solve the AOE problem of thieves, but also control the field in key occasions (for example, a goblin mortar goes down ~ it is a group of 3-second kidney attacks within 8 yards, and AOE skills such as snowstorm are very gorgeous, especially when grenades interrupt casting remotely.
Secondly, I recommend mining, which is a major that matches engineering seamlessly and can solve your economic problems to a great extent. Of course, the words of the rich can be ignored. ...
Then jewelry or leather manufacturing. Many statues in high-end jewelry are tied with picks. These things are very profitable for thieves ~ and they are also one of the most profitable occupations in the later period. Leather drum is also very useful for thieves' DPS, but those are the most advanced technologies, unlike engineering, which can be used from beginning to end.
