Bearius is a massive bear enemy and one of the many secondary bosses in The First Berserker: Khazan found at the end of the game’s various bonus missions. Bearius can be found after defeating the fifth major boss in the game, Aratra, the giant spider enemy. Once you’ve managed to defeat Aratra and free the Blacksmith, Qazumaka, you can return to him at the bottom level of the Crevice and speak with him to acquire a new bonus mission called “Blacksmith’s Heirloom.”
