Ok guys so all you need to tame it is a titanosaur platform saddle. It doesn’t eat anything and you don’t need any narcotics to tame it. Once you knock out the titan, place the saddle in it’s inventory and equip it to the titanosaur. Boom you just tamed a titanosaur! You’re welcome!
if your in mobile don't try to tame a titan near the ocean because the ai of the titan in ark mobile is dumb and can drown themselves so when you are taming a titan if it's near the ocean don't tame it it might have a chance to drown itself
