Level up health and damage and you have yourself a cave killing carnivore. Took my lvl 101 (500 damage, 2500 health, single player) to the cave with the Artifact of the Massive. Came out with about 12,000 Chitin, the Artifact, and the shock and awe of what this easy tame can do. Lay large eggs for Superior Kibble, too. ALWAYS LEAVE ON PASSIVE or else they run off.
Don’t make it listen to group whistles. If you whistle a target it will run off. You’ll have to keep an eye on it. After that, whistle stop on it and/or follow. Oh, and if you see Simon make sure to tell him it’s safe now and come home.
