Seems like after the tlc patch they are harder to down, im on unofficial with damage numbers and it looks like theres no headshot multiplier and it took about 60 hits with a crossbow to down a 150 with fairly regular hits
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.
