For QS, engineering is just an entertainment major, and there is nothing good except engineering glasses. Jewelry has more benefits for QS. First, you can cut your own gems, and some gems with good properties can only be used by yourself. Secondly, several accessories of jewelry are also very good. There are three series of accessories, which are simple to start with and powerful. If you make an alchemy, it will be good for those BOSS who play a protracted war in the later stage, because you can make an alchemy behind the alchemy, and the effect of drinking medicine will increase by 40%, which is very powerful! In addition, the BUFF duration of alchemy has also increased a lot after WLK, so it is very cool to use! If you play PVE, I strongly recommend alchemy, which is both economical and powerful! Especially in the face of the bottomless pit of land reclamation, it is really economical and convenient to do it yourself.
