This is by far the most terrible way to tame a dino. U have to lose a lot of stuff u have worked for in the past for this 1 dino. They should make another way to tame it. I am not sacrificing my dinosaurs for this.
At lvl 72 with flak armor on, a lvl 5 Troodon knocked me out with one attack at night. Last thing I saw was those glowing eyes before passing out. My Guess is that they attack vital organs. Luckily my Doedicarus was up for a game of baseball and launched that little devil out into the stands.
