Eh, what do you do when servers are packed with turd burglar alphas.. you spend 4hr taming a male carno lvl90 with raw meat... and just as it finishes... those turd burglars come eat it up.. the right boulder helps with any knock out... just make sure the place you tame it is OK to keep. :o
You just need a couple trank arrows, at least about nine, maybe some hide armor, and then climb up onto a rock that he can’t get up onto, then shoot him or something to Agro him, and once he comes to the base of the rock and attempts to kill you, shoot him with the tranks. Then when he tries to run away, just jump down and chase him. But make sure he doesn’t get KOed in water.
