The rex can be knocked out in many ways.\r\nOne of them is to stand om the back of a quetzal and shoot from the back of it.\r\nPreferably use tranq arrows or tranq Darts to knock the rex out.\r\nAnother method is to pick up a friend with any type og bird and let your friend shoot at the rex.\r\nWhen its knocked out you can start feeding it with what ever food you got. And make sure you have enough narcotics for the tame.\r\nYou can use spikes around it or have dinos to protect it.\r\nWhen you have tamed it you could put it on a boat to transport it.
So my experience with this beast was horrifying but I knocked it out it took so much tranq arrows it took 30 tranq arrows and I ran fast with the Brontos because there were lots of dinos with the brontosaurus then it was attacking the other dinos then I shot it a lot then it fell asleep because the thing it was attacking a a tank it was an ankylo so that’s my experience with a rex.
Just tamed one I will tell you my experience, so I found one and shot it with tranc DARTS (but tranc arrows work just as well although you need a few more :)) and it kept on getting deststracted by other Dino's which made it not attack me, so after I knocd it out I killed the other animals attacking the unconchis body with my Pump shotgun and gave it raw meat and a couple of bio-toxins and boom I got Rexy I hoped this helps on your next Rex tame
I recommend using a scorpion to tame it, pump all levels into health on the scorpion. Then just attack the Rex but with 10 to 20 seconds in between hits, DO NOT pump anything into dm. Also this is what I use to tame literally everything, and it doesn’t even cost anything. Pls put this up in chat for everyone to go “oh that’s not a bad idea” 👌😄👍
