When tamed the Rex is pretty decent (spino has better utility though) it can be a boss killer for non ark mobile players when damage and health are upgraded plus it’s roar can stun small and some medium creatures. They also have good carry weight for a carnivore and can be used as carriers if you don’t need it for damage

If you want to tame a rex then the best option would be this:

1. Get on a quetz with platform saddle

2. Find the rex u want

3. Knock it out

4. Protect it with your dear life

5. Since most rexes spawn near mountains, when the rex is knocked out say your prayers(if you know what im trying to say)

Guide to tame t-rex

1- get a lot of exeptional kibble or prime meat or mutton

2- get narcotic

3- find a t-rex.

4- go to a high place.

5- shot with a good ranged gun.

6- shot more

7- when unconscious, feed the t-rex with : pulmoscorpios kibble OR raw mutton, OR raw prime meat OR exeptional kibble

8- wait

Use a lot of walls if you don't want to have problems with the resources get a doedicures and a beaver plus a mantis or you can get use a metal pick or a stego or a trike for it I just hate it when you have to be level 74 for its saddle use a long neck rifle with lots of darts once down feed it meat a lot and build a fence around it and put you usefull items there and a sleep bag and boom you have a rex it is good for raw prime or raw meat so it is so great if you want a lot of meat for other carnivores that all and to level to 74 do a note run look it on YouTube they will tell you or you can wait and level up to level 52 and unlock the GPS and it will be a lot easier and get a pt with a carno following you make sure you have a lot of carnos or a good carnivore make sure you put in melee damage and health bye bye sorry this was so long

While most people think of a rex as a disadvantage, I think opposite.

1. Tank. These guys can deal quite some dmg before low, along with hp. I fought a lvl 9 alpha rex with my lvl 20 with ascendant saddle, and I made it up to 12/25K hp before I died & refresh my game.

2. High apex. This creature can be safe from most of the islands threats (NOT TERRITORIAL BOIS) meaning you'll be safe for long distances.

3. Lvls. While people say Luling up is hard, my rex levels up fast. It's pretty useful for combat (raptor dues within 2 bites for me)

4. Rarities/Farming. Albino Rex's can be hard, but truly worthy. Mine is albino for example. Female Rex's can give pretty good eggs as well to sustain hunger, or even kibble

5. Grinding. The rex is useful to collect TONS of meat and possibly hide within minutes of rampage. If your team is mainly carnivores, this rex is useful for getting the food you need. They also don't eat much, so it's also very useful.

6. Taming. If you have prime meat or better, it's possible to not even need narcotics. It takes a decent amount of time, but very time-saving.

7. Abilities. The roar can affect most creatures with a low apex lvl and if their lvl is lower than the rex. It stuns them for a short period of time, and sometimes can force them to drop feces. (Bleh)

Now for weaknesses.

1. Low speed. This dino has poor stamina for running, and can't escape fast enough for alphas (like how the alpha rex killed me) along with not recommending long travels.

2. Bad weight. A rex normally has about 500 weight before its basically sad.

3. Low armor/defence. Without a strong saddle or high hp/dmg, your weak spot on a rex grows.

4. Breeding. I never bred a rex, but It must be a pain from research. The egg takes s long time to hatch, and it eats about every minute, along with growth time.

5. Swimming. The biggest weak spot of a rex is swimming. They dont have enough stamina for long trips, and extremely slow in water. It's a good hinting method, but still.

6. Abilities. Above it showed the good advantages, but there's weak spots as well. The roar doesn't affect creatures with a higher apex or higher lvl than the rex, and doesn't affect alphas. Doesn't affect any aquatic creatures either, and some creatures might even target the rex instead of stunning. (Slim chance, but in some worlds its possible)

7. Saddles. Requiring a high lvl along with tons of material is a true pain. It's also very rare to get a saddle from supply crates as well. I tamed my rex around lvl 40-50, and yet the saddle is about lvl 75.

I hope these tips helped your taming for a rex! Pls up do others may see.
