A simple way to get these guys is to simply distract them with something delicious. Command something tanky (Ex. Carbonemys) to attack them, then set them to passive so they don’t kill the Carno. Then, you can pelt it with a slingshot or bow and tranq arrow until it goes down. They don’t have the biggest torpor stat, so raising it to max won’t take many tranq arrows (5 if it is extremely low level)
⚠️Do not attempt this if the Carno is in a pack!⚠️
Ride a raptor with your taming weapon of choice, preferably a bow + tranq arrows or better. As long as your raptor isn’t encumbered you can out run the Carno! I suggest pumping some movement speed points in your raptor but this is not necessary (I didn’t). Shoot the Carno with your tranqs and chase it once it flees. They’ll be knocked out and then you’re free to tame it! I did this on a lvl. 55 female Carno and it worked (I named her Éclair).
