What is your major? PVP or PVE?
PVP is a good project. Very good. Bombs, grenades, helmets, parachutes, and so on, and so on.
PVE has great advantages in jewelry processing. I also play table clothes. At first, I practiced leather making and engineering, but now I have changed to jewelry and forging, which cost a lot of money, but only for the bonus of dragon pupil stone and the forged hole in wrist gloves!
Engineering has little contribution to PVP.
The harvest of a dragon pupil stone, especially shooting and hunting, is great. The level of armor-piercing projectile directly affects your output.
