I often get asked where I go to farm $$ in the game. Here is my favorite $$ spot. You must be able to access the reality switch in the Tundra. As a Ranger with powerfull AOE skills this route is very profitable; some classes may fair better than others here. Basically farm the red slimes. The red slimes spawn several mobs and both the slimes and mobs have a chance at dropping rare loot. Keep what you need and sell the rest. I suggest keeping the rare loot and gems that drop, and trashing the rest out of your bags to make room for the good stuff.
