Inside of the Kronus Fight in CIS Kronus will spawn adds. (You can tell when he does it because there is a message that appears on the top of the screen). These adds are level 32 2dots and they each drop platinum coins. You can easily get 70 a fight. As long as the person on the quest summons him and drops the quest you can do this endlessly. What we did is have 1 level 50 go up there and fight him till the adds spawn then stop fighting and go reset him and rinse repeat so we didn't have to wait for him to respawn. I have about 900 platinum coins on my bard. Happy Farming
Cheers
