Gorrel's In-game portrait
Gorrel, Turncoat, is a Unique Brigand found in the Wynton Courtyard in Act V of Diablo III. He spawns for the Noble Deaths event, as a leader of the band that murdered the nobles opposing Lord Wynton. Upon being discovered by the Nephalem, he was genuinely surprised to see that killing the noblemen (with women and children) did not encourage the hero to join the peasants' rebellion.
In combat, he has Fast and Knockback affixes. His Brigands assist him in battle.
Upon death, Gorrel drops The King's Note to Lord Wynton.
