I found a lvl 135 up in the mountains with three carnos, nothing too high level. Tamed him in a pillar box with a ramp after many attempts and finally downed him. I kited him with an argie but was very difficult to kite him without get affected by its roar. I killed its carnos by getting them agroed on other creatures and killing them with my high level argie.
