OSTO features 25 World Bosses (WB) scattered across Arborea. This guide outlines their locations along with the most efficient ways to reach them.
World Boss hunting is primarily achievement-driven, with objectives found in the Encounters and Exploration section of the Achievements window (default key: “V”). Completing these achievements provides a natural, goal-driven way to explore the world while steadily introducing new challenges. While some WBs are easily soloable, others may require a group—even for players in max-level gear.
