I saw a tip saying snow owl is the easiest way to tame, allow me to one up you... net gun... walk up to a mana that is attacking something, wait for it to almost comepletely kill the thing, hit it with a net. Place 2 stone dinosaur gateways, One below the shoulders and One above, tranq quickly till knocked out (cause they can break stone) and feed exceptional kibble. boom. I was taught this trick and it made everything SOOO much easier.
