Gnome and goblin's choice task LM is in Ironforge, BL is in Jingya City. Note that the task is level 40, and you may not find it if you are at a higher level. Look for it.
There are two tasks, you choose the department, and now you can't learn the other if you learn one.
The goblins go to JJS, and the gnomes go to Treasure Bay to continue their mission. The task is for you to make some engineering products.
The master engineer is under the tent in front of JJS Hotel, and there is no goblin trainer.
1. Goblins and goblins have two transmission effects, one is outland and the other is earth. The effect of gnome's transmitter on the earth is to become a mouse, a demon twin or directly fall to death ... while the effect of goblins on the earth is not only to become a mouse and a demon twin, but also to directly kill people ... In the transmitter of outland, the effects of gnomes and goblins are the same, and there is no difference: randomly changing tribal figures, randomly changing alliance figures, bright souls (you are transparent yellow) and dark souls (you are transparent gray red)
When studying engineering, you must remember that there is no way to modify the branches of engineering. Even if you practice again, it's useless and there is a certain chance of bugs. Neither side wants you. The modification branches of other majors can be forgotten and modified by trainers, and there are also some settings in the project. There is a book by the sea in the upper right corner of the map of Garkison. You can forget the branches.
The above is also found from other places! I hope I can help you!
