So check this out...
Thief steals an axe at the blacksmith early in the game. He uses it to build a raft and get into the middle region. The thief travels to the warlock and gets quests like deliver gold or objects which are 3 out of the 6 possible quests. He then steals the required gold or objects from players to get a talisman. He continues this process and claims all the talismans so none of the other players can get them. If a player happens to get a talisman from the deck or a card then the thief just pounces on him and steals the talisman back.
No talisman means no way to win the game and the thief can just ****** this victory card right from under your very nose. Is the thief broken or what?
