I just tamed a lvl 20 theri and it took 1hr and 200 narcotics. This thing was a pain in the bootycheeks to tame but well worth it. It gathers a crap tone of berries, rare flowers, rare mushrooms, and also a good amount of thatch/wood. I recommend having around 50-70 tranq darts if you want to knock out a high lvl theri.

Watch your back these guys will chase you forever unless you jump on a bird and fly away these guys want to make sure you get the best tickles before you leave!

Me: Tries to kill a lv 4 of these with a lv 74 Spino

Theri: Does at least 5,000 damage to me

Spino: Has only around 16,000 health “ouch”

Me: Thought that would be a easy opponent since I destroyed everything in my way barely taking damage from them

This thing is soo good but it takes abt more than 100 biotoxin to tame but trust me it will be worth it.

I only got a chance of taming this sort of early in game because managed to find a good spot on top of a tall rock where it can't reach, and shoot tranq arrows. Scared to tame a 2nd one. It killed me in like 2+ swipes as I still was new then. Now the same Theriz that killed me once is my best friend.

These guys are very tough to beat early and potentially mid game. If you have a Spino or another large carnivore mount, you can destroy them easily. They also can drop keratin so you can use that for cementing paste and other recipes.

I have 2 powerful raptors and it can kill it fast but my raptors have to heal up.

Its hard to kill because if you want to go on a rock it will come to no matter how much its height

Tips on this annoying thing.

1: It has terrible vision and mainly uses sense of hear, it won’t see you u less you are a couple raptors away in length. 2: I know lots of people are saying to outrun it… but it really hard it runs really hard so the best way to get away is to get one something high.

3: If you are looking to kill/tame it you need to build a big tower and rain fire down at it the best way to do this is to get high enough so it is out of range of you so it won’t attack your builds, if you do this right it should look up at you and you should be able to hit it in the head. 4: The things you need to kill it are just a crossbow/bow and around 100-250 arrows (this depends on how much you miss and the level.) Spears work too but not as good, then you just need good walk speed and a good tall structure. 5: These things can kill a player in a couple hits because I’m pretty sure it does percentage damage instead of just regular damage.

I know all of this stuff because me and my dad were playing trying to explore when one of these things attacked us, dad eventually killed it for revenge and it was awesome seeing it dead. But my point is that I wish dad would have tamed it instead but killing it was fine but a waste of arrows.

Always keep a trike with you because the trikes knockback will stop it from killing you helping to kill it

YO my first time seeing this thing I was like WOAH I never knew Wolverine was a dinosaur, then I saw me and I was like PLS SPARE ME and it was like ahha not today buddy I ran al FAST as I could but it still killed me so I was like IM GONNA TAME YOUR KIND ONE DAY and the a few weeks later it finally happens.

So you wanna tame this big chicken eh well young one you are gonna need 9 large bear traps,50 tranq arrows (just to be on the safe side take 80),a whole lotta berries and bio toxin cause this bois torpor rate drops fast

So first things first grab a pterandon and your large bear trap your bow with the tranq arrows and a sniper rifle with 10 bullets

Then find a theri once you find one find a open space where you can see it clearly so i doesnt sneak up on you and make your efforts useless

After those place your large bear traps on rows of 3 then go back to your desired theri with your pt and shoot it once with your sniper and bait it to your bear traps and just spam its head with the tranq arrows wait for it to fall and voila you just knocked out one of the most dangerous chickens you ever saw in your life

Then of course the usual taming with the berries and bio toxin

NOTE: DONT LEAVE IT FOR LONG CAUSE ITS TORPOR DROPS FAST AND IT MIGHT ESCAPE OR KILL YOU AND YOUR PTERANDON

This guy literally took hours to tame. I recommend getting TONS of bio toxin, normal narcotics aren’t effective enough, and TONS of berries and or vegetables and most importantly you’ll need TONS of patience

I would recommend to tame this guy with kibble because it takes 4 hours to tame a level 100 if you use berries

VERY DANGEROUS CREATURE Be carful use tranq DARTS

Large Bear Traps are inefficient, you gotta get on a high and steep rock and tranq it; chase it when it flees and continue to tranq. I’ve gotten them unconscious but their torpor drops very quick and it can be dangerous

If you have spike walls all over your base sometime when it kills this beast it will go flying

So I was flying to my neighbours island with her, and we had to stay on a mountain to regain our Argys stamina, as we waited, I looked around and saw THREE of these guys, I’ve heard a lot about how these kill, so I was freaking out, one was attacking a rex?one was coming fowards and backwards to us, and another just staring into the forest (we lived tho, yay! :3).

I saw this thing roaming around my camp in singleplayer once (in a area near where the southern coast and the southern jungle meet) and decided to approach it, BIG MISTAKE! It attacks you, and I suggest if you ever do what I did , you have a medium amount of stamina to run, because I was running away from the Therizinosaurus and it hit me while I was running. Best thing to do is build a spiked wooden wall and wait for it to die.

If you want to kill one of these I would recommend a trike if your low level, and you may be questioning... how? Well just Mount your trike and attack when the theri gets close enough to not be able to land a strike but you can, but then you would need timing though, and with the knock back that trikes have you can kill one, and other creatures are optional, but just remember! Timing is key.
