Here is a easy way to tame this creature1. Get a few bolas (just in case you miss or a there’s a pack)2. Get meat3. Find and bola raptor 4. Knock out with club/fists 5. Put meat in inventory Boom! now you have a raptor!
They can escape a trap made of doors on Ascended. I didn’t see how (I’m guessing they fit through the door space now) but I dropped one in a taming box made of doors 3 high and was parking my Argy when I heard all this commotion and he was going nuts on my tames I had set to Passive.
