Tame a lvl 150 breeding pair with highest possible taming effectiveness, get them to max level, breed them, get the baby to 100% imprinting, get the what was the baby to max level, get the parents to give it mate boost, and attempt to kill a titanosaur! (Give them ascendant saddles for high armor and give the what was the baby a bionic costume!) A full imprint max level giga can kill a titanosaur so long as it has high armor saddles!
