I was easily able to tame a low level one in the redwoods. Let one attack your pteranodon and lead it to a tree platform. Tranqed it while it attacked my ptera and it fell asleep on the platform. Easy way to do it solo without a trap. Darts work best for knocking out quickly
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.
