The Ravengers are good for collecting meat and hide, as they are good fighters, and they have 2 different attacks to collect. The swat collects meat, and the bite collects meat and the secondary resource(s).
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.
