All you really need to do to tame these guys it trap them, the way I did that was with 4 stone dino gateways and a bear trap all you have to do is place the gateways in kinda a u formation kinda spread apart not touching so it’ll actually fit the guy in there then just get a bow and shoot him to get him to chase you run though it he’ll get stuck in the large bear trap and then place the last gateway behind him he took about 15- 20 tranq darts depending on the level
