If following the usual method, the way to kill a Tier Nine Barbaric Beast is to slowly wear it down over time, each time relying on sheer force as the main force, while other Barbarians harass from the side, allowing the sheer force to batter the Tier Nine Barbaric Beast till it's covered in bruises, eventually losing combat ability and getting killed by them. But this outcome means that all the Barbarians, including sheer force, end up utterly exhausted, giving other tribes the opportunity to take advantage of them. Last time, the Thunder Dragon they hunted was snatched away like this.
