The Hunter is an assassin appearing during the quest Open Season. It is a Shiro'ken, and is in a group of Shiro'ken Assassins. In the game's lore, The Hunter is an unrelenting master tracker that cannot be killed, only delayed. Powers imbued by the Lich Lord allow The Hunter to resurrect his body, no matter how many times he is defeated.
This boss has many similarities to the Beast from the Chainfire Trilogy of the Sword of Truth novels. In Chainfire, the Beast hunts Richard Rahl relentlessly by detecting his magic, and no matter how powerful the attack is upon its body it cannot be killed.
