So, to tame a Spino you will need 4 gateways, large bear trap, narcotics and tranqs. First, place a trap (like a rex / giga trap), lure the spino in to it, close the entrance by placing fourth gateway. After trapping it, start shooting it with tranqs, until it's knocked out. Put narcotics into his inventory, and collect meat. I prefer getting raw prime fish meat from Sabertooth Salmon, by using Sickle. After feeding the spino with meat, force feed it with Narcotics. His torpor drain is very high. And that's how you tame it.

Now, let's move into his attacks, buffs and other things. First, is hydration buff; when a Spino gets into the water, his dmg, Heath regeneration, and speed are better. Now his types of attacks; claws and bote attack. First, is claws attack; it's losing his speed, to gain more melee damage. It can turn around in that position. Nów, bite attack; better speed, worse damage. Best option to out run danger.

If you want, ^ this, if not the not. I don't care about that, I just want others to know about Spinos.
