It’s actually really easy to kill these, and they give a lot of prime as well. I kill lvl 20 paracers with a lvl 30 barry, and get around 30 prime when using my pick (I also have 5 times gather amounts on my server though, but it will give a lot of prime with normal gather rates as well).
These guys give a good amount of prime so if you’re looking to tame a giga or a rex with prime these are a great way to get lots of prime meat. It’s also easy to kill one of these if you have a high level argie.
You can find these guys chilling around and in the swamp and redwoods on the island. So long as you evade all the crocodiles, snakes, carnos, the occasional Rex, you shouldn’t have an issue locating and taming your mobile base/turrets of death.
I have a whole army of these guys a total of seven of them three of them have platforms. They are unstoppable. The one in the middle I named WORLD PIG and a an eighth one in my base so I can pack it with materials if I am raided and I manage to escape.
