Tips & Strategies
Although it technically can make Behemoth Metal Gate frame, your Argy is unlikely to be able to hold ingredients in its inventory.
More Argentavis Saddle Tips
a good way to get metal is to breed a pack of argentavis and make them follow you when you go to farm metal because they have a metal weight reduction so you can carry more and don't forget to get a ankylosaurus for more metal
A good way I found to get chitin is farming the scorpions with a axe you get like 120 -140 each
Works as a smithy but you can’t repair things in it
Kill trillobits and you will get a lot of chitin
Kill bugs to get the most chitin
Try fishing if you are not high enough level to get this
don’t bring your bird in to a sticky situation
Tame a saber and cave or look for bugs they get around 40 chitin per kill
You can use it as a smithy I got an Argy earlier today
