So, I've been doing this for 4 hours, and I figure it's a good thing to share...
What is it: Easy chest farming in Ramparts and other instances with chests guarded by humanoids.
Works with: All classes
Best for: Rogues, blacksmiths, and engineers (to open locked chests)
Requires: The Plague!
Step 1: get the plague and go to Ramparts.
Step 2: Zombie up inside the instance and start puking on as many mobs as possible, especially the pack guarding the first chest next to the first boss.
Step 3: Corpse explode on any big pack of mobs you missed, or the boss and his two friends if you've not got him infected yet.
*Corpse exploding causes your death to both infect others and cost no durability.
Step 4: return to the instance. In your absence the zombies have begun eating the living, thinning them considerably and leaving only the non-humanoids alive. in Ramparts the only survivors on the first floor up to that chest should be the non-elite dogs. Kill or avoid the dogs.
Step 5: Attack one of the zombies and get re-plagued, kill that zombie.
Step 6: Take chest. 5G and a green or blue BOE, usually a potion as well.
Step 7: Zombie up and head up the ramp. Infect the top floor. Corpse explode to die.
Step 8: Rez, return to top floor, and kill a few dogs for the second chest.
This awards just over 10G and two BoEs (often blue) in 15 minutes. The Gold/hour isn't high enough to say this is a "ZOMG Awesome gold!!!" farming method, it is quite possibly the most fun I've had alone in game.
Tested with a 67 rogue and 70 mage, no problems doing this with either one.
