From my experience the higher level ones are always in the lower safer area of the desert dome near the desert titan cave entrance watch out though there are rumble golems and mantis there, in the cave.no special way to tame them and no technique just move towards one with a cactus broth on and some flak Armour if its a high level . Then just shoot out with tranq arrows just make sure you stay in melee range or else it my shoot at you and if it does you will die.
