If you can get on top a cliff with a rex at the bottom, it won’t be able to reach you. Shoot tranq arrows/darts till it starts running from you, and then keep shooting while you chase it. Eventually it’ll pass out. Make sure you have a ton of prime meat and/or things nearby you can kill for prime meat....

I’ve tamed 3 rexes this way

3 to 4 stone dino gates in a square big enough to fit it inside and you good no bear trap or elaborate taming cages required. : l

Level up the speed so you can go faster than the dinosaur and there would be a time for the narcotics to make him sleep( this works for many dinosaurs)

If Your a savage like me just make around 20 tranq arrows and make it chase you. Then you shoot it until it gets knocked out, but this method only works on a low level one

If you don’t want the long set up to tame, lead one like any creature to the bottom of a cliff, fly up or shoot it from the cliff and tranq it. When it starts the run, watch the cliff fall if you’re chasing on foot.

I go on cliffs and dart them from the top until it gets knocked out kill and large animals preventing it to die and put spikes around it and feed it all the meat you have on you.

Best way to knock out is to make a stone raft and put it slightly in the water so when it knocks it won’t drown. Has to be at least 2 walls high.

If you are feeling a bit lazy when you tame a Rex just lead the Rex to some high terrain like a cliff and fire away. But if you wanna do it the smart way build a trap with a bear trap and while the Rex is in the bear trap close the trap that you led the Rex into

You can usually lay between 1-4 large bear traps down in a line and stand just in front out of reach of them and shoot them with tranq arrows or darts.

Make a stone or metal octagon out of Dino gateways, but leave one for the behemoth. Put a gate in the behemoth, but not the regular ones. Set the behemoths pin code to your preference and close the gate with the keypad AFTER luring the Rex inside. The Rex can’t fit through the regular Dino gateways, but you can, allowing a safe easy tame.

The rock scaling allowed after the TLC phase 1 makes using rocks and even large cliffs illogical, if the cliff has even one section that’s less than a 65 degree angle, that Rex WILL climb it. Even after they nerfed it a little, it can still walk over most anything. I would suggest stone structure pens with a ramp to let it in, it will also derp through even small gaps between the 3 Dino gate strategy, the moment you realize that, it will have escaped and be coming at you.

What you want to do is use a cross now or a normal bow it works just bring a ton of narco arrows and some normal narcos to keep it knocked out make sure you have some other ok battle Dino with you so you can kill what ever is there a use that to tame it

Before you go hunting for meat MAKE SURE YOU PUT UP A SPIKE WALL TO KEEP DINOS YOU DONT WANT OUT

That is very important bye

If you find a cliff and get the rex to follow you, you can shoot down at it with tranq whatever-you're-using until it get knocked out.

Keep under Rex's belly towards tail and fire KO ammo upwards at the belly. It can't bite you near as much because turning circle is so large.

Using your pelagornis fly to a safe distance and land then run up on it using a crossbow and tranq darts while you're back peddling hit it with darts jump on pelagornis and repeat

Ride on your pteranadon in every direction you can furthest away from it. Jump off and hit it with all the tranqs you've got.before it gets too close jump on the pterosaur and fly away. Repeat until its down. Never tanq anything in deep water.

Just find a rock it can get up and fire at it then get down so it dosnt run away and then get back up

I play on PVE so I can't use high tech tactics. So far I've tamed about 6 Rexes, 3 of which were lvl 145. (Still looking for the elusive 150)

Anyway the tactic that seems to work the best for me is to kite the Rex to a large shift in terrain. Something the Rex can't walk over. Honestly doesn't have to be much tho, they seem to get stuck on even smaller rock formations.

Once its stuck hit him with a bunch of trans arrows. (You can always break the rocks with a pick axe to get it out once it's tamed.)

Is use a taming raft with a ramp and a basic wood ramp parked behind. Aggro on a bird and lead into taming raft. Land bird on basic raft just behind and shoot arrows from it. Sometimes with taming rafts rexs can still get the occasional nibble on you hence the second raft. I take them back to my base near swamp and farm paracer for prime.

Tame scorpions for eggs before you try to tame a high lvl. Scorpions are an easy tame even if they are lvl 150. Kibble makes it an extremely easy tame a rex because you'll rarely need to use any narcotic.
