Absolute godsend for meat runs in caves. Only things that'll aggro up on it are Pirhana, Megalania and (presumably) Megalosaurus. Otherwise, everything else (including Arthropleura and Sarcos) won't aggro. Have at 'em!
It's great at collecting berries, fiber and chitin from insects/bugs. He also doesn't collect charcoal from the burnt trees near the volcano in ragnarok anymore. Great for fighting broodmother and doing artifact runs on the island and caves that are filled with insects. Definitely worth taming
