No trap required. Get a fast mount that you can shoot from while riding it, like a raptor or baryonyx, tranq it while kiting, let it flee to a safe area before dropping it, then secure the area. Starve taming works best.
I recommend using a scorpion to tame it, pump all levels into health on the scorpion. Then just attack the Rex but with 10 to 20 seconds in between hits, DO NOT pump anything into dm. Also this is what I use to tame literally everything, and it doesn’t even cost anything. Pls put this up in chat for everyone to go “oh that’s not a bad idea” 👌😄👍
1) Insta Tame an Argy (get close to knockout drag a body so it eats and gets the healing effect this will drop its hunger so place whatever food you have for it and will be instant tame works on any level!)
2) Get that argy as a killing machine I recommend health n melee I use a 4.5k health one
3) Knockout Rex
4) While Rex is knocked out bring that argy around and kill whatever is near for prime meat I look for paracers
5) Tamed Rex
Please give this post a spot at the top if this is useful!
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.
