These devils do sooo much damage and can run like Usain bolt, but they can't see well so if you are getting chased do this 1. Pray the Ark gods are on your side 2. Run around near trees and get on high rocks. I, a level 26 was trying to tame a level 14 Theriz and died 3 times eventually I got on a rock and shot around 20 to 30 tranq arrows till it got knocked out I didn't do any research so I gave it meat, but they only eat mejo berries, vegetables, and some kibble so I had to run back to my base and get some berries and fed it, luckily I had a magic Brew thingy majig that made it tame faster and that's how I tamed it. If you don't have tranq arrows unlocked don't bother. (Btw I play on mobile).
