Tbh, i tamed 12 argy by using at least 20 tranq arrows and a crossbow, a flyer, put it on passive, and let em attack the flyer. I reccomend using around 50 tranqs [if on 150, the medium hardcore] or 25 [For 30, the easier hardcore] I also reccomend using cooked meat like raw prime or cooked prime b/c it works better than normal raw meats
