Thought I would hate the taming method until I went and fought a max level with my bison. Just make sure your bison has ~10k health and 300% melee, fight it until it roars while making sure to feed it corpses or disposable tames when it’s low and you’ll have a easy time. (Extra note do not use the charge attack of the bison, the simple headbutt will suffice and if you mess up throw a disposable tame or simply run until it heals and calms down)
