The one where you have to collect the debt from 3 diffrent npcs - Well don't turn in the quest, just keep asking the ogre at the bar for the debt and he will continue to respawn within 5-10sec of death and drop about 50 silver each time. He's really easy to solo and you get rested xp while you do it.
We eventually turned in the quest after killing him 50 times out of sheer boredom, but maybe someone can use this to a more sinister means. . . .
