Quest bosses:
In a word, they’re pathetic… Most of the time, you can oneshot them… really anticlimactic when it happens to Marnox or such supposed top demon lords. When you reach maps of level 100+, you start to meet elite monsters that are actually harder to kill than the corresponding bosses on the map. Basically… the PC got massively buffed in term of magical/physical attack power, but the quest bosses didn’t get such update. Please consider upgrading them for more fun when questing.
Field bosses:
These should really be SMARTER. I mean… you enter a map like Demon Prison, kill harugals and such that instantly try to kick your ***, and meet some kind of huge arachnid that looks like it could eat 100 little characters like yours for breakfast, but instead just say “Hello, how’s the weather today?” and doesn’t even retaliate when your archer shoots at it. Free loot? Sure, but I’d like to get more fun out of it… Please consider giving them a brain.
