How I did this : I built a trap two walls high (these things are kinda tall) lead it into the trap ,put crops and bio toxin in its inventory,went to sleep in game woke to it at fifty percent taming rate when the other day it was 20 ,waited,feed it toxins,went to sleep again,now it’s 80 ,waited for it to tame cause I couldn’t go back to sleep for a while,it finally tamed,now I have a level 7 theri .(yes I know it’s low level,I’m low level okay-)

Therizinos are very hard to tame since they are fast and very strong. Plus they aggro once close by it which we all know happens to us. So try to get a high ground which means no close combat only ranged. Meaning no fists and clubs. Only bows, cross, or a compound bow. With tranq arrows. Or darts if you can make a longneck. Once knocked it will take awhile with mejo or crops. But Have a lot of narcotics or narcoberries if you have a harvesting dino with you.

How to tame this bird:

1.make trap like base 2 wall high

2.Place 4 wooden ramp so theri can climb in

3.clean all tree and rock so you can lead theri go to trap with no problem

4.For make him stay longer place giant bear trap

5.Shoot him

6.Feed him soothing balm 10×(u can get it free by daily gift)

7.Feed him crop

It’s ok to be afraid of these guys, if u wanna tame them however, you are gonna have to be a bit brave. Put your tame(s) on passive, grab your weapon of choice + ammo, 16 stone pillars and a large bear trap. Using 7 of your pillars, snap each in place with one spot left empty (For the theriz to enter). Place another 7 on top of your current pillars (so there’s two “layers”) and place the large bear trap somewhere in the middle, comfortably away from the edges of the trap. Now get your theriz. You can snipe it or punch it to agro, whatever is comfortable for you, and run to your trap. Run immediately behind the trap so the theriz runs right into the middle and gets caught in the bear trap (if it loses agro just shoot it and it should run over) . Swiftly move around to the back and place your last two pillars down, one on top of the other, walling the theriz in. Stay away from the trap edges and start tranqing the theriz. Stay calm and keep a slow but steady rate of tranqs. As soon as it’s knocked out, pause the game and take a breather, you have done the hardest part, now, just put in your food and tranqs and monitor it’s progress.

Well what are you waiting for?! Stop reading this and go tame it! You can do it!

Sincerely, a wholesome gamer :)

To random lvl 37:

High ground, mejoberries are among the best, narcs to use are bio toxin (around 250+ or so, depending on the level, to get just kill the jellyfish) crossbow is alright, but tranq dart would be better. Go for the head, check hp always with a spyglass, then let it recover a bit if its health is too low to prevent you from accidentally killing it. Make sure the high ground you’re on is a CLIFF facing big rocks (this thing can walk over rocks so watch out for that also can push trees out of the way, dunno if that is a glitch but whatever). Always have a flyer at the ready, ptera is good. Taming pen is a bit hard because this bastard can damage stone with its beak attack, which can also give you torpor if it hits you. Also equip a shield, just in case. Saved my ass from lvl 130+ theris in case a hunt went wrong. Best armor to use is flak, no more no less if you wanna fight this guy, tho it can melt flak and also pierce straight through that. Pissing it off then climbing to a nearby rock a sarco can climb on spells instant death for you. Killing this as a lvl 37 is impossible without a good sword and shield at the ready. Spino also takes good care of killing this bastard. One mark for a therizinosaur is if there’s too many herbivores in the area that should normally be filled with raptors or terror birds. You’re gonna need a ton of tranq arrows to knock it out though, with a certain chance of death.

If you tame one of these and put spike walls around to protect it while taming beware titanoboa can come right through the spike walls and attack like they are not even there. Also clear the small plants and underbrush away so you can see it coming because they can sneak through the plants and attack your unconscious tame and you won't see it until too late.

1. Get A LOT of trancs

2. Find a steep/or where it can’t hit you and you can see it (at least the small part of the tail

3. After finding the cliff face find a theiz. Near or right under you

4.Part 1) Get kibble and a good soothing balm (I prefer the major than the minor) (I friend with the regular one but the other drowned and took both the kibble and soothing balm TwT) btw it only takes one kibble with the major balm

4.Part 2) get enough food and a small or any balm tranc it and for this you HAVE to have a lot of narcotics

5. After knocking it down DO NOT LEAVE IT FOR OVER A MIN! It will wake up IMMEDIATELY so warning about that before you go all “O NO I HAVE NOT ANY FOOD ON ME, LETS GO GET SOME!” And don’t feed it flowers it will wake up and start running again I have been though that well I force feed it because it would not eat it.

Tip #1: have somewhat of a flyer so no need to travel on foot for that will take longer.

2x3 stone fence foundation. Stone dino gate on one end and doorframes 2 high the rest of the way around. Bother it, run into the trap, out the doorframes, then place the door on the gateway and start shooting. *DO NOT USE A COMBINATION OF DOORFRAMES AND WALLS FOR YOUR TRAP, IT WILL WALK THROUGH THE GODDAMN WALL LIKE NOBODY'S BUSINESS*

I git this unconscious but suddenly it was going to fast i can't craft a ton of narctics and can't capture some jellyfish then i decided to leave it alone i might die that day but i chose to not NEVER get close to them if you don't have tames ready and long range it can kill an army and always look around whenever you see the danger sign
