The Witcher 2: Assassins of Kings -
"The chief conspirator is wearing Seltkirk's Armor. Relieve him of it. During the fight, keep your distance from him until you've killed his cronies. The armor makes him tough, and they'll take you from behind while you engage him if you don't dispatch them first. Go find Dandelion in town. Confront him about the propaganda, but keep his secret. Then go see Dethmold. Tell him you found the conspirators and ask about a reward. Tell him you don't want coin. Then ask more about the curse.
