I heard you are quite the hunter and monster slayer! If you want a real challenge, you should try some Trolls! Tons of them down south just running around, all crazy! As a bonus, the Rolsburg Militia usually has bounties on them. Travel to Rolsburg and speak with Captain Holsgrave, if that interests you! Good luck.
Welcome to Rolsburg. How may I help you? Oh, so you want to be a Troll hunter, eh?
