run to split paw upper tunnels invis and run the the guy that drops the key for the 5 chests that are in the back.. kill him .. invis up again run through the spiders to the chests and open.. loot it invis back up run out and repeat.. very easy way to fill up your trader 
made a good bit of money doing it so far.. sometimes the guy with the key doesnt spawn.. so you have to zone out and back in sometimes up to 2 times.. but still garunteed chest each time.
