These things can pierce armour which is why it takes out players so quickly. If you need to fight it keep your distance and shoot at it from afar or use a tanky tame to kill it (preferably one u can shoot from the back off).
If you find this thing RUN it took me out in two hits and completely demolished my home and murdered my raptor and my little otter cuddles please like to pay respects to my little cuddles kept me warm on the cold nights
In the summer of 2019, I had just finished of my base and was living happily when suddenly one day I heard this beast outside my front door. I was scared cuz I couldn't run anywhere.I was only lvl 39 at that time but only had a raptor and a trike. I watched helplessly as it wandered closer and closer. I had now realized that I can only fight. I equipped my rifle and then...BOOM! I had shot at it! it came running towards me and started smacking my wooden base. My raptor got hit and started fighting and so did the trike, BUT DAT THING RIPPED DEM BOTH APART IN UNDER 30 SECONDS!I shot at it again and the next thing I saw was its massive claws upon me... THE END(press F to pay respects for claw(raptor) and spike(trike)
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.
