If you wanna tame a Rex here is what you gotta do.
First place a bear trap then put metal or stone gates around it (3) .then leave an entrance for the Rex to come in then when it’s stuck in the bear trap build another gate behind it and there you have it it’s trapped now you can punch it or tranquilize it until it ready to tame /thx for reading
Ez to tame tamed mine recently you dont need to build traps you only need a stone for the rex your gonna tame then shot it in the head using crossbow and tranq arrows use prime meat and normal meat if you dont have enough force feed it narcotics or biotoxins to increase its torpidity up if you found this helpful.... -XxCooldude12349xX
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.
I would think these were gonna be harder to tame but they’re actually not that hard, my stamina and movement speed is pretty high I’d say around 200 or higher but I didn’t need a trap or any of that, all I used was tranq arrows, u shoot it once then run away for a little bit turn around quick shoot it again then run away again and shoot it again and repeat, if it starts running it means it’s almost knocked out just chase after it and keep shooting and feed it meat!
