The Manticores here have an amazing drop rate on Hair, which sells for 4k pretty darn fast on the AH. Hides sell for quite a bit and so do fangs. If you're having trouble selling the fangs on the AH, feel free to vendor them for 600gil a pop. The best circuit to run in this zone is... Begin at the Kuftal Tunnel, kill the two here and then follow your right hand wall. There will be two at the end of the map. Follow the map down and you'll hit a wall with two more, kill these guys and swing over to Revolution Rock for two more.
