I can earn about 150k / hour.
$$
is very important in these kind of MMORPG games. You have $$, you
can get whatever items 'wu lu wu lu' items that you could never
hunt. 
hey based on my personal experience... you should take into
consideration what ores / materials you have to get at the present
moment. One or two ko is ok one lah. For my case, when I was at low
level, I will chose those places with low spawn rate to kill two,
three ko monsters. And those high spawn rate to kill one ko
monsters. And I got LOTS of pots from one ko monsters then used
them on two / three ko monsters ( Save cost ). Comparing these two
types of killing, the experience, they are almost the same.
By the way, can any one tell me where to hunt for red whip
pls?
Please correct me any one?
