Wolf Hunt 3 is the last wolf quest from the innkeeper. He will ask you to kill the Wolf Leader, who lives at the top of Wolf Hill. I believe that most classes can kill the Wolf Leader at level five, maybe six. You will know the leader when you see it, the wolf is purple and apart from the other wolves. Return to Innkeeper Kashim when you are done.
Reward: 750 EXP + 50 gold + 3-pocketed bag + a weapon (weapon depends on your class)
