Taming these amazing dinos is pretty easy, as they are slow and don't bits as fast as a spino. If you have a Bird with 2k health or more you can use it to tank the rex and shoot tranq arrows. Or if you have 126% speed you can just run and shoot (which is what i do). if you're at a place with q lot of Rocks i would suggest running behind the larger Rocks and then tranq. Once it's down you shouldn't have to wordt about anything as their torpor drops very slowly and nothing But allos attack them when their down. When you get a 110+ put your first points info health until 15k, then 2k stam and the rest into melee and you have yourself a alpha Slayer.
