The weight of raw metal, stone, wood, fiber, and thatch are all halved in their inventory. Great for travelling as they can jump and travel along natural and manmade ziplines, even when following. Also good for combat, highest level has alpha status and they get a pack bonus of +4. Can gather fiber and mushrooms with their claw attack from a some wild mushrooms. (Have been able to collect from blue mushrooms, but not the red or brown ones.)
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.
