Going off of my experience of being raided and killed by many of these, they're very op. I had 700 health and it killed me and my pt in one hit. I personally never tamed one but all I know is the taming process is very long and stressful. Goodluck and if you see someone on their tamed rhino just run (just kidding you can't run because they're way too fast).
These rhinos might be endangered But they are actually keeping their number from 300 to 2050 At my guess they’re actually strong whenever I met my first one I thought it was a big deer wolf and they’re easy to kill so I tried to kill it and till I saw its face that’s why I knew it was a white rhino and then I was like OH CRAP and then one charged me and it was a level 200! I recommend you take them for PVP and if The person you’re reading has Tourette’s Bring some stegosaurs because they are good against Tourette’s
There creatures are almost entirely passive, so long as you don't attack them. If you do aggro one (to kill it for either it's great pelt supplies or it's horn), it is best to get on top of a small cliff or something like that. Running away is almost always futile, as not only do they move faster the longer they charge at you, they do up to 10 times as much damage. If you are to run, don't run straight, unless you'd like to be a rhino's horn decoration.
They are everywhere in the snow mountains. A group of wolf or smilodons will aggro them and if the rhino is high level, you can tame it but don't forget the bad boys who want to eat it, protect it from the smilodons that served as tank for the tame.
