Tranq arrows are fine, shoot in the face, walk backwards and continue shooting in the face, if you can shoot the underside when he turns, then go ahead. It is a little difficult to time that however. When it starts to run away from you, just keep in front of it and keep shooting it in the face. If for any reason it rolls up into a ball, let it go and find another one. If you are intent on taming it, put a structure around it to keep it safe, then sit by it for about 45 minutes to an hour, it will heal faster if you are within render of it. Leveling up the melee allows it to collect more rock with each swipe of the tail. If you are so low, put most of it in weight and some in melee, this will allow you to collect more with less trips. If you have a tribemate, and you are using a Quetzal or a skiff, then only level melee.
Once you're deep in tranq darts trying to tame this, punch it... I punched it and it unwound itself to start running, punched it again and it became unconscious.. almost used 15 darts before I knew the shell absorbs half torpor 🥲🥲 he's a level 2 😂
Love these creatures! I got an ankylo as my first utility animal thinking it would get me a lot of stone, but this is guy is the way to go. I just did a run for stone on my island and got over 1,000 stone just from a few river rocks. And they were small. They aren’t bad at swimming either and I love the feature of the rolling! So cool
