Build a taming pen from 5 or 6 Dino gateways and two gates. Space them roughly equally apart leaving enough space to run in-between the gateways to get in and out, but not so much space that your tame can escape.
To tame one easy all you have to do is kill something so the argent Avis can eat, and while it’s healing you must knock it out with tranq arrows or darts. If it is knocked out while healing it’ll starve immediately and it’ll tame in seconds no matter what level!
If you lose your argys go to the place that shows your character press the tames button which says how much animals you have, Look for your argys name press request, then wait. It will tp to you, if it’s alive.
