Here is how I did my one.

1. Go to Carno island.

2. Locate your Rex.

3. Use a raptor to make it Afro on you and run to the small cliff on Carno island.

4. Make sure you are at the top of the cliff and your Rex is at the bottom and shoot at the Rex

5. If the Rex somehow manages to get up the cliff. Just get on a raptor and run of the cliff(don’t worry, it’s not high enough to take too much damage). Run around the cliff fast enough so that when you get to the top the Rex is still at the bottom.

6. Repeat until knocked out.

P.S. there are better ways to do this like using a trap but this is how I did mine so this is kind of a cheap way of doing it.

Anyway happy taming!

How to tame a rex:

1. First, you need to bring 4 stone dinosaur gates. And a large bear trap.

2. Place 3 of the gates (in this shape \_/) and the large bear trap inside them.

3. After you've found a rex, lure it and get it stuck in the trap.

4. After the rex is stuck in the trap, quickly place the fourth gate to prevent the rex from escaping.

5. Now knock the rex out with a tranquilizing ammo like tranq arrows or certain darts.

6. After the rex is knocked out, feed it meat or preferred kibbles.

Hope this helps!

You can also do the exact same thing to tame giganotosaurus, but with metal gates.

My next tip will be on diplodocus!

Easiest tame ever u need 15 to 50 tranq arrow depending on level and a 700 hp iguadon or gallmis (seriously) with a crossbow run and hit him till knocked out feed it anything u got wait here is ur rex and after u get 2 u have a infinite rex factory ( a spino is better but harder than this to tame in early time)

Pretty easy to tame as long as you are prepared. Always bring extra tranqs and narcotics to be on the safe side just because it takes a lot to bring them down. Upgraded rifles and crossbows are a godsend and make it even easier too. Get a Pteranodon or Argentavis, find a cliff/high ground where the Rex can’t get you and make it rain with darts and arrows. And when they start to flee once their torpor increases, run it down and don’t let up. I don’t make/use traps but this tactic works well for me. The giant murder lizard will be yours soon enough! Happy hunting and good luck!

You need only tranq arrows, a crossbow, a flyer, narcotics, and a type of meat for this method

Look for a Rex on a mountain and get on a level above it. High enough that it can’t get you but low enough that you can see it and shoot it. Then shoot it with tranq arrows until it passes out. Fill its inventory with narcotics and the meats of your choice, feeding narcotics if needed.

And there you go. Your new Rex is tamed

Hope this helped!!

How to tame a T-Rex for dummies:

1. Find a mountain or forest biome, Rexes usually spawn in these biomes.

2. Head back to base and craft up a ton of narcotics, I usually go with about 400, but I always over-prepare. Also, make sure you have at least 80 tranq arrows, or you might not knock it out.

3. Find a high rock with a flying dino, an argy is perfect, and do NOT underestimate how far up it can hit you.

4. Hit the Rex with your argy and guide it back to the high rock mentioned earlier while it’s aggro’d, hit the T-Rex repeatedly, and go for headshots.

5. The Rex will wander away from time to time during the process, make sure to hop back on your argy and remind him who’s boss. (Aggro him again)

6. After it’s Torpor is high enough, it will eventually flee, don’t get too close to it, but follow with it with your argy, landing and firing tranq arrows occasionally.

7. It will eventually knock out, and you will NOT want to put any food in its inventory yet. Instead, put it on a tracker and monitor its Torpor from time to time. Now would also be a good time to go and round up some prime meat, which is an excellent, easy-to-get food for the Rex.

8. Return to the Rex with your prime meat, (a little extra never hurts) and feed it some Narcotics, to raise its Torpor again. By now, it’s hunger should have dipped a considerable amount, and now you can put the prime meat into its inventory.

9. Protect your T-Rex while it eats up, some creatures will attack it while it is KO’d.

10. Enjoy your T-Rex! (And make sure they have LOADS of food in their inventory at all times)

Quick tip cuz I learned this:

It really isn’t that hard to tame one depending on its level (for this example this is gonna be a low level one). For the bare minimum, you’ll need tranq arrows, some kind of bow, and a lotta meat (if we’re just talking about raw meat maybe like 80 would be good). If you can’t outrun the Rex, have some kind of speedy creature with decent stamina. Again, in this example I’m talking about low levels (1-45 I think). If it’s a higher level, investing in a trap might be better.

I am a noob,level 24, and I knocked one of these bad bois out without a trap or anything.

Explination: I grabbed thirty tranq arrows,thirty-six narcs and went over to a cliff and started shooting it took only 13 of the arrows because #1 im on mobile, and #2 because it was low level.

I hope you enjoyed my lil explination :)
