3 metal Dino gates placed before hand (no doors on them) with 3 bear traps in the middle aggro the spino then lead it through the gates place a 4th gate while it's stuck then you're free to tranq , wait till the "tranq used" notification disappears to tranq again to perfect tame
A good way to get it unconscious without a flying dinosaur is by making 10 stone pillars, 10 wooden ladders then climbing up the pillars and shoot it with tranq darts or arrows, it can't break stone fast so ur safe. Pls don't use less than 10 pillars, I tried and I got pushed of the pillar and just died:( Sorry for my bad English. Hope this helped
These guys are rlly hard to KO without a trap because they LIGIT will not stay on a single target. If they see something that they will Argo on they will turn around no questions asked, which is kinda rlly annoying when you’re tryna knock ‘em out.
