This thing was an amazing tame for me! With a lot of upgrades put in towards health and damage I have been able to defeat two alpha rexes, three alpha carnos, and MANY alpha raptors. Also putting in stamina for It I had a tribemate pick me up and was able to bring down a level 36 quetzal. These things are OP! It’s horrible you can’t bring them in to fight the bosses. It would be an easy fight because they can’t reach me. Except for the dragon.
Getting a massive TLC update in March 2018. The saddle will act as a mobile smithy, Argentavis will be able to carry with Talons as well as with its beak, reduced carry weight on obsidian and a few other unannounced resources (similar to the mammoth and wood), and will also gain a Rapid HP Regen upon eating (likely from devouring corpses and not specifically food from inventory). Like so people can see!
