I tamed mine at the edge of the cold area , I traveled there on the deer creature , the taming things I used where simple I used tranq arrows with a cross bow , quite simple so just charge at it with your cross bow and knock it out (Be careful don’t die ,make sure your in an area clear of dinos that eat unconscious argies or just kill them) put the taming food and put spike walls around just in case something comes , when I tamed mine there was a cliff and I knocked out the argie at the bottom so I was at the top of the cliff while taming it it wasn’t cold there so I could stay there nice and warm and checked on my argie with a telescope and went down and checked on it . Once it was done taming it I requested it to the top of the cliff put spike walls around it (just in case , you would heart broken if it died after all that hard work)and rode home (remember to put some food in it’s inventory so it doesn’t starve to death ) and ride home the happiest man in your ark world and request it when you reach your base
