They are the best bird to tame for mid game. Just make an argie trap with four Dino gateways and two gates space them out a tiny bit, at least to be able to shoot a tranq arrow with a crossbow, spam tranqs til it gets knocked out.
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.
