Fulgorge

Fulgorge is an underground worm. He lives under the ground and can't be targeted with any of the macro's. However you will still be able to target his body, making the macro still somewhat usefull. The most common place that Fulgorge spawns is nearby Falcon Watch. So if you're hanging around looking for a place to farm I highly reccomend the valley southeast of Falcon Watch.

As with every other rare mob, I highly recommend farming for 10-15 minutes then mounting up and searching all of the locations they spawn. Fulgorge is on roughly a 1 hour spawn timer.
