Not really useful tame, but they don't do any damage unless they push you off a cliff. Their attacks are all pushing, no damage. Awesome giant walking prime meat machines to kill and harvest when you are taming something useful. Or tame one and name it the Magic School Bus and drive you and your entire tribe off a cliff into the Volcano.
I would recommend one for player vs player gameplay because these guys can tank hits like it's nothing. these guys are very useful for travel to but maybe use for a mobile base for maybe taming in single player. I would put health, weight, food , and speed mostly. I hope this is useful for you ❤
