The best way to tame an allo is to find the level that you would like and kill off the rest of it's group but if u want all three just get to some high ground and then just start shooting them with tranqs
Think about this: The taming in ark is crazy. The last thing the Dino would remember would be you impaling it in the face with toxic arrows before it gets knocked unconscious. And then somehow it eats while knocked out which makes no sense and then wakes up and loves you till it dies.
