Bosses in The First Berserker: Khazan are quite challenging, with the difficulty increasing as the story progresses. Viper is the third boss, appearing at the end of Mission 3 at Embars Temple. As the leader of the dragonkin, he possesses a scale of Hismar, granting him enhanced power and the ability to wield its energy. Players will face him at the Heart of the Forgotten Temple (Scarlet Nexus) after shutting down the rotating machine beneath the temple.
