You hit it with cannons on a quetzal. Go for it’s head. It’s torpor won’t drain either so take your time. They can’t eat just stuff a platform saddle on the titan once KO’ed. You use daedons to heal it when it’s food level is low.
If you try taming these guys, tame a Quetzal first and equip it with a platform saddle. Then, put 2 storage boxes on it and a cannon. Make sure you make LOTS of cannon balls. Then, shoot the titan in the head.
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!
