(INSTANT TAME GUIDE)If you shoot tranq arrows, wait for it to flee and then give it a dead body to kill while it has high torpor. It will get rapid regeneration for 20 secs ( green essence on the head) if you knock it out while it has this green essence you can instant tame as the food is depleted instantly.
If you need an argy and don’t have time to tame one with a trap, just go to carno island, kill a Dino in front of an argy and let it harvest its body. When the green health icon shows up on top of it, knock it out with tranq arrows and the argy is instantly yours.
