In mobile, if your names last two letter and griffins last two letter is same they respect you and in mobile i knocked out it but he didnt eat the meat you must use allo kibble or griffin kibble. (please click up button for everyone see)
Best place on Rag to find Griffins in the mouth of the river that runs through the canyon, right next to the swamp. At least 5 different spawns in this area, I've seen 3 in one spot before 😂😂 hope this helps anyone looking for a good taming spot!
