Step 1- Get good armor and a ride with darts.
Step 2- Don't be a pansy
Step 3- Go out there and shoot the Rex in the face to show it who is the man

Spinosaurus has entered the chat.

Rex has left the chat.

There once was a rex called Paul,
Who stood about 15 feet tall,
Use tranq arrows or darts,
Straight to his heart or
You'll struggle to tame him at all.

When I first started ARK I spwaned in the northeast of the island and I saw a rex..... I was like WOW THIS IS COOL soo I attempted to get closer to it but he looked in my direction. Immediately I stood still on the beach thinking he won’t see me BUT he did and within 6 seconds the game read - “BOB was killed by a level 123 rex!”

The best way to tame a Rex is with one single item, a forcetame. They only require one and they’re yours. And the best part is they won’t need a saddle!
