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
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 doesnt say but these things are a godsend on scorched. Can collect alot of silk, cactus sap,fiber, and berries. If you take it out into the dessert and have a decent level megatherium you can kill deathworms and mantis' untill you get bored.
