If you do the RTE quests, it will introduce you to all the areas including where the bosses and their minions are, while giving you items to do it. Otherwise, I suggest exploring the outer edges of the map.
Hey NineArts, I am getting destroyed by these mobs in Qingdao, they take 1/3 of my HP in one hit, and the lack of leech from the trap makes grinding in that map really challenging and frankly not enjoyable at all. How do you overcome all of this?
