It’s really not that hard a tame. Trap it with stone gateways and a bear trap. Knock it out with maybe over 100 tranq arrows. (Which aren’t as hard to get as you may think). And BOOM! You have your self a rex. Oh yeah and feed it some kibble, for best taming better stats AND less time for taming. I would say it’s a medium tame.
Dont be scared of them, get a flyer and make sure to have a high health and stamina, fly at him (make sure its only one or your dunso) and let him take a bite of your flyer once in a while then lead him into a square wall of dino gates with a trap in it. Once he is stuck quickly close up the open gate, laugh at him and shoot him (alot)
Okay so people are saying to use platform saddles which yes is not bad it’s just work to get a quetzal, if you have 2 people all you have to do is build 3 stone Dino gates in an unfinished square away from the Rex, then get the Rex to aggro on you and lead it in and go through the middle square (you can use large bear traps but I never use them) and then while the Rex is still aggro at you the second person needs to come behind and place the last gate.
If you use the bear trap strategy which is if you lead it into a Dino gateway that is shaped in a triangle and with a bear trap in the middle (Large Beartrap) and when it is stuck you must put a dinogate behind it to trap it and then knock out. (hope this helped and "If" I win could it be an Xbox voucher, thanks.)
Just shoot it with arrows while its killing stuff. Make sure you dont get killed while shooting it on the ground and try not to knock it out while its killing something that will kill it if the rex falls asleep. Not a lot of stuff tries to attack a rex for obvious reasons so you should be fine not putting protection around it like spikes or walls. Just bring a flier just in case it starts running at you. They have a short attention span and have bad mobility. I recommend using kibble as it wont take as long and will give it a level boost.
When breeding two max level rexes to have a super baby, DON'T EAT THE EGG!!!! I've done this twice on accident(meaning to drop it) and each time it takes me a couple seconds to register wtf I just did and then I have to wait to mate again. Sad day. Weekend ruined. Great way to start off the new year! Lol
May I just say if you are on a cliff and see a red shoot it with frank arrows in the head. I’m only level 30 and can’t believe that I have a rex. This red is a beast, he kills like a monster. I would just watch out for Therizinosaur.
