I have some rexes in my single player u have to be very careful when trying I tried once I got arrows and the bow broke so I used a sling shot and it knocked out put some meat in it and I had a rex!

I found the best way to tame aggressive and more dangerous creatures is to use Tapejara (saddle acquired at level 55). They can land on high and vertical surfaces while still allowing you to shoot. If the tame is not close enough to the ledge, I suggest shooting it or Argo-ing it to follow you. This method helped a lot i was able to easily tame a spino and Rex.

This is basically the go to choice for almost all the bosses.why? because its the one of the best for fighting bosses especially forest,ice and megapithecus, because point you probably don't have a giga at that point,it has high HP and high damage and if you breed it up..it's gonna crush the weaker bosses.if you want to add up the damage output of the Rex with the yuty then sure you can do it if you're willing to go into the snow and possibly get ambushed by purlovias.

Well I don't know if it happen in pc because I am good with mobile control and play ark mobile but for me rex is soo much easier then taming spino you just need a high place where rex can't reach you and hit him with treanq arrow or tranquilizer dert until it got unconscious then just feed prime meat it won't take lot narcotic 10 is enough for me I didn't even needed narcotic I tamed a mex level rex without narcotic

You can find these bad boys in the mountains, snowy parts, and in the red woods. Use around 30 tranq arrows/darts to knock them out. Feed them raw prime meat or raw meat if you have the courage to wait and boom got the king of the dinosaurs.

Low levels are easy, get on a high rock and have a bow with tranqs and a spyglass (to watch its torpor) and when it runs away it will be knocked out. (I did this on carnivore island)

Go to a high place shoot it with tranqs and feed it raw prime meat don’t do extra

Ride your Iguanodon, use other dinos as bait and just shoot it with tranq arrows, darts etc. Add: you can knock it out while on a cliff or when it is stuck other is using a large beartrap. Always bring your escape dino with you Incase something attacks you.

I’ve killed 90 of these with a primitive sword and 500 health

How to tame: get tranqs and meat and some narcs and bear traps. Spot a Rex. Watch Rex get eaten by spino. Tame spino instead.

To be honest spino is easier. It costs Less narcs meat tranqs and levels for saddle. It is more powerful then a Rex on its hind legs. I don’t want anyone to be mad but the Rex is weak compared to the spino. I suggest skipping the Rex. Unless you have a tek rex saddle I would never tame one. Tame some yutys and spinos instead. -lava

The best way to tame it is to stand at a high point the shoot like any other dino then build around it a spike walls and let its food level drop near half while keeping it unconscious with bio toxins(make sure to take enough 70 just to be safe)

You can even explore a little around then when its food gets near half feed it any kind of meat doesn’t have to be prime and it will be tamed under 30 sec

Be careful when taming these guys in or around the swap. Leeches, if nearby, can and will attach to them after they're unconscious, and you can't remove them until after the dino is tamed. Beware the leeches.

I saw a Rex near where my base is and I didn't want it to get closer so I took all my stuff out of my inventory and I ran up to it and led it to a Wolly Rino but it killed the Rino than I just led it further back so it wasn't as close to my base it was just a level 4 with a thousand health but I didn't really have great tools so I led it off!

To tame a rex at low level need 3 large bear traps place them in line. Agro the rex it will stuck in 1st bear trap then start shooting tranq arrows ....then it will stck in second continue shooting tranq arrows ..pow rex is uncounsious .... but its little risky.😁

The safest way to trap a rex is to build a 2x2 square STONE foundation, add 4 STONE door frames on each side, and add four ramps to make one big ramp on the side your going to lure the rex into. Then, just have it chase you into the taming pen you've made, and get yourself out through one of the door ways. The next safest, but a little bit more risky and resource friendly, would be to set up 2 STONE dinosaur gate ways to make an angle, with a LARGE bear trap in the middle, so that once you lure the t rex into the LARGE bear trap, you can place the last dinosaur gate way behind it so it won't get out. Then, use a nock out method of your choice. Once it's nocked out, put your taming food of choice in it's inventory, and wait for it to tame up. No creature of my knowledge attacks an awake or unconscious rex, so you can go far away from it for a while if your in an area with other Rexes.

A rex’s utility is to tank damage while also putting out damage, it is VERY useful for boss fights such as the megapithicus, the brood mother, the dragon, and the overseer.

The rex is not especially hard to tame. There is several options in how to do it.

1 stand on a cliff that is higher then the rex an shoot it with tranqs of choice. It will start running when the torpor get high.

2. Use a thyla or wolf or equus or any other fast tame that you can use weapons when riding. Shoot the rex with some tranqs of choice and run away a bit. Shoot again the run away. Repeat untill the rex start to run away and then run after the rex and shoot till ita a sleep.

3. Use a Griffin and fly above it and shoot with tranqs. Fly after and shoot with tranqs till its asleep.

4. Have a tribe pick you up with an argy and fly above the rex and shoot tranqs and then fly after when it starts to run.

Hope it was helpful to someone 😊

To avoid the long taming time you can adjust taming speed before you join your worlds :)

Bring extra supplies then what the app says. I noticed sometimes that it’s not accurate. I put 200 tranq arrows into a 145 X-Rex and it didn’t even start fleeing. Sorry Dododex…

Rexes are very good against most bosses if you have high level ones. They have very high health and damage
