Hello everyone there! Well, many 9Dragons have question about the location of bosses. Now I found a little map showing where the bosses are. The author is Yukimura90.

Okay, look at the map, the red dots is the area the boss spawn. I hope it could be helpfull for you. Enjoy!

Map

-Lowest level boss is at Great Snow Mountain.

-Second Lowest is at Great Snow Plain.

-Second Highest is at the far west of North Sea Road.

-Highest is at the north west of the lake near the "S" in the word Summit.

Umm,that's the map. Aas you know,bosses are red for Humble Master players, as long as you get around the mobs, you can kill it with a party . Hope it is informative.Good luck!
