Today I went hunting for the World Boss located on Nar Shaddaa, I found him after a short taxi ride to the south. Here are some text based directions if the map isn’t doing it for you:
1.Take a taxi to Network Security District, or take taxi to Upper Industrial Sector if you don’t have that, then turn left into Republic Research Division
2. The “Systech West Elevator” located at 1680,2880 brings you to an area in the Network Security District which you will find while doing the Nar Shaddaa bonus series.
The boss seems to drop level 28-35 epics, but there is a growing loot table at TorHead if you are interested in specifics.
