We're talking about Tempest Keep: The Eye here. Particularly we'll be killing mobs in Novice Astromancer's room. Each one of them drops 1g for himself and a good chance of epic items.
As you enter the room you'll see some mobs on a platforms, on each of which there are mobs of 15k HP and one of 100k HP.

Basically what you want to do is pull the pat that is walking around the boss, near the platforms, and along with it pull one of the groups on the platforms. The platforms are linked together so that the mobs on the nearest platform get pulled once you pull the others. You'll kill the 15k mobs fast, but keep the 100k mobs alive until you get Mind Controlled, but keep in mind that they Mind Control A LOT, so you might not have time to loot all the mobs. Once you get Mind Controlled, the 100k mobs will get back to their platforms and the 15k mobs will respawn.
Here's a picture of how to pull.
P.S. I haven't tried to solo it. We did this 3man, but I think 2man will be satisfactory as well.
P.S. 2: It seems that this gives ~1,000 gold looted/hour totally, and along with the trash items, epics and cloths, it might be way more.
P.S 3: Thinking of creating a video soon. IF ANYBODY wants to create one, just upload it, and I'll put it here on the main thread!
