So there's this lvl 145 Rex that spawned right in front of me while I am cooking meat for jerkies. I was low in health 'cuz I just fought a high lvl bronto; solo with an ascendant sword. It was attacking a Trike and I checked its lvl because I wanted to tame high lvl Rexes to make 2 super pet Rexes. I wanna tame it! But with one munch, I died and my Diplodocus came to the rescue while my other dinos were just too far to detect my death and my dilpodocus being attacked.
So when I respawned, I set all of them to follow. Even though it hurts to kill the Rex, I just don't have a choice. I made it bite me and all of them went crazy and attacked it in a frenzy for 10 seconds, and I watched it be killed in front of me. However, after the fight, my other Anky died and I am shookt as it was my diplo that tanked the Rex and my 5 well-trained raptors took the power, 2 Argies, 1 stego, 1 oviraptor, 2 dilos, 1 saber, 2 doedi, 1 scorpion and another anky. They are all high lvls and well-trained.
