basicly u get cheap ports to hunting grounds where the clan hall is, for exemple w/ aden clan hall (http://img148.imageshack.us/img148/948/adenchrl5.jpg) u can port to all hunting ground in aden area. about 95% of the ports are the same the town gatekeeper offers, remaining 5% are unique ports (pre-c5 clan halls had many unique ports but they got removed w/ the teleport/gatekeeper redesign :( )
