Everyone says these guys are powerful. Not to me! I practically live next to them. I adapted to them and I already have about 5. All you need to do is get on a rock where they can’t reach. Then load them with tranq arrows or darts. I make a lot of kibble, so taming them is not to difficult to me. But still be wary of these creatures as they do kill you and your Dino’s fast.
If you want to knock it out effortlessly, place a wooden cage and lead it towards the cage. It will start attacking the cage. You can shoot it with tranq arrow and BOOM! You have made it unconscious. Also, it eats berries.
