As I say in the title of the post it is impossible for me to kill the King Rhino at the oasis north of Muriela’s Hope. I currently play solo and my character has level 51 and heavy weapons / armor. I have seen on YouTube videos of players who “catch” him with fences, buildings, etc. I have tried but when he is locked inside he “disappears” and returns to the oasis.
Could someone help me and give me any hints? Thank you!
