One thing you can do is get a flyer I recommend a argue or pteranadon and get a truckload of tranq darts and meat it worked for me plus I wanted to get revenge for the time it killed me my tamed and base

It takes more time and resources than Dododex says

The Rex said that the torpor rate I drop is high. I disagree. I have tamed two rexes with raw meat and I did not need to use any extra narcotics or narcoberries. All u need is a bow with around 40 to 50 tranq arrows, and meat of any kind. Find a rock that is high enough for u to shoot the Rex and knock it out,

For instant tame you have to just run underneath the rexs and tickle it’s belly no kibble or prime needed

A rex like a argy has a blind spot where it can't hit you just stay on its tail and run in sircles blind spot is behind him close up sometimes you'll get hit but make sure you got good armor when he starts running chase the coward down

I have Alot of Rexes destroy my a base if your place destroys your base, step one, you should tame some of trisiratops.step two, build your home of stone...why? Because Rex can't destroy the stone....I hope I can help you

1. Hit it with tranq darts or tranq arrows until it gets too drunk on tranqs and is knocked out.

2. Put lots of raw meat in it's inventory (if you don't have any just find a nearby dino to kill)

3. Remember to feed it narcotics to keep it from waking up while you're taming it

4. hooray you have a t rex now

Actually I never thought I can find these in the redwoods forest. I'm on mobile so I don't know for PC/Console.

I was out looking for high level rexs on what I like to call the Viking map. When I couldn’t find any good levels I went to the lava island and found a level 150 female Rex. I killed the low level that was with her and started shoting traq darts when she started running I had got so scared when she ran into lava. I stopped firing and luckily she got out before she died and I knocked her out and tamed her.

If your taming a Rex then you need 1 pulmonoscorpius kibble and 3x soothing balm it will tame instantly if you are in easy mode

They can CLIMB small cliffs. Only the biggest rocks are safe …

Get a long neck rifle and bullets just in case things go south and bring a crossbow with 50 to 100 tranqs and make a trap with four behemoth gates and shoot it

Me and my sister were playing ark when not one but 2 alpha rexes show up out of no where rip jimmy,dream,john and Lisa the giant dodo(they where mammoths 🦣 and one giant dodo)

What I just learned was apparently if you run through a very dense forest with a lot of tiny trees they get stuck and confused in their AI doesn't know what to do... I had a trap and everything and he couldn't make it to the trip because he kept getting stuck in between trees

Have more then one person with you and get trank darts

Rex: taming you are going to need: some food any flesh meat and also have smoothing blam to for faster taming also get the cheap one if you want to buy the more faster taming ones if you are on hardcore and also the most best location is the volcano near the red woods forest but saber tooths love that spot so be careful and kill all threats: have a pt or a argy and fly out try to avoid the red woods because those things love to jump off trees and kill your flyer: start shooting the head for faster knock out: once it's knock out *put your food that you chose* and start the taming once it's up take it to your base and the Rex do have a roar and bite attack:

Also if you want it to your base super fast go back to base put your Rex on attack target so I don't die and put it on sit mode go back to base and request your Rex back to base put it in a comfortable spot you have your own Rex I appreciate your time for reading this and have a very good damn day...........

Do not take a low level rex to fight a lower level allo it will destroy the rex an then u R.I.P emerald

I got 2 good rexes and now I have a army no need to tame 100 or more just 2 good ones

I sacrificed a larger high lvl turtle and while it was fending off the Rex I tranq the heck out of the Rex. My turtle had about 1800 hp and I used about 25 to 30 tranq arrows I'm not sure how much meat I used I put in about 2 stacks

Took me so long to knockout and it glitched into the ocean and drowned 😭😭
