Whenever you're taking the Spino, remember to take at the very least 300 narcotics. It wakes up FAST, and whenever your taming ANY creature, surround it with wooden spike walls! Saves me countless tames from smaller pack animals. And to knock it, you simply need steep high ground and go to town with your tranqs. Happy taming!
Place 3 stone dino gates and one giant bear trap in middle, shoot it and boom here he comes... While he is on trap place last stone dino gate on the back ez tame. Really good in swamp everything fears them and kapro cannot grab you while standing in 2 legs.
I got mine from hopping on beefed sarco shot it with tranq arrows on crossbow and with about 16-20 it was tamable so then throw prime or regular fish meat and should go easy as long as you have at least 30-45 narcotic or 15-20 biotoxin with you
