First off, this guy will ruin your day so you better be prepared to lose a few birds and lives in the process. Secondly, It takes way more than 46 tranquilizer darts. I had my whole tribe(5) and it took us a solid 30 minutes. Keep in mind it was only level 10. Once you put a few hundred tranquilizer darts and arrows it in, it is super easy to tame. Give it about 50-150 narcotic and a few prime meat and it should tame very quick.
I dare you to raise one!! They are savage if you got two high lvl parents (about lvl 140ish) and you get imprinting on it. The thing will become an adult with about 230% melee and basically one chomp any bronto!!! But on the down side you loose your job and your girlfriend
