The Dunkleosteus inhabits deep ocean areas and is best tamed by luring it into a trap or safely kiting it while targeting its unarmored body with tranquilizers; protect it while unconscious and feed it suitable carnivore food, maintaining its torpor as needed. It excels as an underwater harvesting mount for oil, metal, obsidian, crystal, stone, and other minerals, while also serving as a durable fighter. However, its sluggish movement and poor turning make it vulnerable to faster aquatic creatures. When encountered, keep your distance and avoid being cornered, using its low speed to escape or applying hit-and-run tactics.
