Taming one will make a lot of stuff easier for you. Some items like metal will only count half their weight in its inventory. And they have quite a lot of weight.
You can even walk on all the slacklines, natural ones or even the ones you can shoot with your crossbow. And you can even walk them up, hang upside down and turn around on it. Made farming metal for me much easier :)
Even just two of these guys can kill a karkinos, I was out on RageElixir (my ravager pack alpha) and a karkinos was blocking our way home. I have all my followers on attack my target and went after it, two of my pack members got stuck but RageElixir and one of the males went ham on the karkinos and killed it. Can’t complain about free polymer
Gathers a lot of oil from tek dinosaurs - usually somewhere between 30-50, which is great way how to get oil in abberration! Also good for gathering the remaining resources from teks and org.polymer from karkinos.
