15 Toughest Bosses in The Entire Witcher Series

The Operator – The Witcher 2: Assassins of Kings

Perhaps one of the most, if not the most, irritating fight in the game, The Operator has a personal shield, Gargoyles that can easily back-stab you, fireballs, melee attacks and the ability to teleport. Stunning the Gargoyles with Aard or destroying them instantly with Igni is essential but possessing armour that negates magic damage is also pretty helpful.
