Build a small pen. Find compy. Lure to pen on foot. Close gate and lock them in. Now you have time to go get prime meat on a Dino. Empty your held inventory into the Dino. Pick up the narcs first, then the prime meat. Trank them out. Use the “transfer all” button at the top of your inventory. They can start eating while you keep them tranked out.
I found a level 1(by chance), and it took me 14 seconds to tame. I found thirteen more over the month, and by February(found my first one at January), I had an army. I took down a whole Allosuarus in seconds with the army, but we had a PVP war, and..........eleven fell to my enemy's Trexes and Baryonyx. Only one remains now, and I keep him in my ark Basement.
