Easiest, cheapest method to knock out any level Rex is simply build 1 stone foundation,3 walls and 2 doorframes(no reinforced doors needed)....place the foundation down and the 3 walls in a U shape on the foundation then in the gap put 1 doorframe and the other doorframe on top....Then run up to the Rex tickle its balls and once u have Agro make a dash for your contraption run through the doorframe....Spin around, go into crouch and start firing tranq darts at it through the door frame( don't worry it won't be able to bite you as the doorframes are 2 walls high) This works on gigas too but go 3 wall high on door frames and use metal instead of stone. Hope this helps fresh spawns :)))

If you're having a taming pen made out of stone (or else) on a WOODEN raft, don't use it for a rex.

It's great for a LOT of dinos, but a high level rex will destroy your raft to dust (and all structures attached to it, no matter what they are made of) before you knock him out.

Tutorial on how to tame a Rex without trap:

1.find it

2.make it follow you and jump to the high ground

3.make sure the Rex won't be able to walk up to that high ground

4.shoot it with a lot of tranq arrows (crossbow recommended)

5.it gets unconscious and you can buy a minor soothing balm in consumables of amber shop which costs 10 ambers

6.feed it raw or raw prime meat or raw meat (you don't need to use any narcotics if you used the minor soothing balm or feeding it raw prime meat without any soothing balm)

7.congrats,you tamed a Rex.

Want taming this in early game?. Just use crosbow with tranq arrow, find high cliff, and keep shooting. No trap, no chain bola or etc, just run in case if this guy try to escape from u (u r faster more than them). It takes 12 shoots with 3 miss on me (free aim not only head shoot). Put at least 100 raw meat on its inventory, and also 15 nacrotics just in case this guy wanted to wake up earlier. G L

I was going to tame a spino and successfully I tamed it by shooting from a cliff nearby then after putting the food I saw a rex closely and then with my bryonx I again climbed the cliff and shoot a few more tranc arrows I was not planning to tame it but since it went unconscious I used 3× smoothing bam and I got my spino and rex at the same time and I only used 44 tarnc arrows which also included a few misses. And now I not afraid of any dino on the island.

To be honest, I tamed 2 Rex's and one of them was hard to get because it was under the snow

So if you wanna tip on taming a rex quicker without anything except a weapon?

Get it stuck or climb up high enough so it can't reach you

Then Tranq it (50-100+ arrows) then if you want to save time
