Well this isnt exactly a guide... but It will help
So youve decided to be a Hunter?
If you have this is the breakdown. A Hunters main goal is to kill thiefs. Aiding a Trader is just an added bonus with some money at the end if the trader is nice and decides to reward you for your heroic efforts.^^. Now you can attack any thief you see. But be carefull they can attack you. Generaly hunters begin lvl 30+ for health reasons

. To become a hunter simply equip a hunter ID bought at Jangan, DH or Hotan.. There is no difference between the 10k and 1m Hunter ID.. Just that the 10k had 3 spears and the 1m has 5 spears on the back.. (only Visual)
