"Mastering Classes in Diablo 4: Best Builds and Quests"
To start the Barbarian quest in Diablo 4, players must reach level 15 and look for a Priority Quest marker in the Dry Steppes region. They must then find the Blacksmith named Gerti in Ked Bardu and complete a quest to be admitted into the Oxen Tribe. Once completed, players will be awarded with a crest of the Oxen Tribe.
