I use 16 stone pillars in a box formation and stack it 2 high with a large bear trap works decently well and is pretty cheap. You could only it use only 8 pillars and a large bear trap to make it cheaper. All you have to do is setup the box and leave it open put bear trap in the middle and have it chase you into the trap and simply slip through the gap in between the pillars and when it’s stuck in the trap go behind it and use the last 2-1 pillars I have and seal it in. Works great I’ve used this trap for other tames such as wooly rhinos and a yutyranus probably works for rex’s too.

Make a 3x3 stone floor surrounded with 2*height double door frame. This will make a cage that you can enter and get out simply but not the therizino. Then add some rams/stairs leading into the cage. Lure the therizino into the cage and knock it out easily with tranquil arrow. This cage trap can be built on a raft as well.

I was killing alpha raptors with my 150 Rex and was leveling it up and out of no where the monster started attacking I tried fight back but I had to run I ran until I ran out of stamina and choose to fight I barely won but my Rex had 1k health left (out of 15k) and it was only lvl 80

I see a lot of debates on how to tame this creature, so here’s my way(the most mediocre ark player)

Prepare of course, you need..

6 STONE triangle foundations

12 Stone doorframes

2 Wooden Ramps

A LOT of Narcotics and i mean a LOT, like you could drown Colonel Sanders’ Wet Dream in it(its a giant chicken.. i’m not funny)

Quite a few tranq darts with a good Longneck

A fat pair of balls

Hide sleeping bag JUST IN CASE

Find a Therizinosaurus AND MAKE SURE YOUR TAME ISNT NEAR IT, these things are like spiders, you turn your back on them for one second and they disappear like a horror movie stereotype, Set the foundations up in a hexagon shape and place 2 doorframes on each side, add 2 ramps on one side(this’ll be used to get the Theri into the trap)..and set a hide sleeping bag close to the trap incase you need it

This step takes a big pair of balls, fire at the Theri and let it chase you, run up the ramp and make sure the Theri does too, run out the doorframes and then the Theri will fall into the trap.

Knock it out then stuff it’s inventory with extraordinary kibble and narcotics, don’t leave it there or else it’ll wake up because Wildcard wants us to suffer

Name your new Therizino! They’re great harvesting but they’re great for killing the Dragon, pair them up with Rock Elementals and Deinonychus and watch them shred that guy to bits and pieces

I saw alot of people complaining about the fact theri's being aggresive even tho it eats berries so to answer ur question i will say that u should go and stand in front of a wild elephant (which eats grass, herbs, ferns, leafs etc if u didn't know) and see wat happens and then u will know why a berry eating dino is aggressive against u

(For mobile) Tamed a level 405. How? Grinder amber early game and bought the cooking station. Got ready a soothing balm until I have the right equipment. The equipment is either compound bow—get a ascended one from quest, with toxicant arrows, or a longneck rifle with shocking tranq darts. Make accordingly following the demands shown in this app and get 6 megalosaurus kibble from the cooking station. Get around 5 large bear traps. Set them up and shoot ‘em while luring it into ur bear traps. Once knocked out, feed the balm, than the kibble. There. Ez 400+ lvl theri tame

i am so angry right now. ok so i knocked out a therzino today in the water i was like oh no it’s gonna drown then as i fed megalo kibble and the first feed was 26% then i thought everything was ok since it wasn’t drowning then i gave it soothing balm(10x) and waited. ThEN A SARCO KILLED IT i killed it with my ascendant sword but then the therzino died…. moral of the story don’t knock a therzino out in water
