This boys are the best carriers to farm resources in mid game.
You can put a magmasaur in a criopod, take it to a local with lots of metal/cristal/obsidian, collect everything you want. Then, drop all the resources in a bag, aim at the bag with the hawk in your shoulder, press double F to throw it in the bag and quickly ride your flyer and go to your base. The hawk will follow you with all the resources in the bag.
Just remember the flyer must be faster than the hawk, otherwise it will reach you and drop the bag.
Not only does it retrieve your items if you die (everything - IF it can handle the weight!) but it can fetch bags for you!! On Xbox, double tap Y with the bag in your line of sight and Fjordhawk will retrieve it for you. It will highlight bags with a little icon of a skull and crossbones in a black circle that pulses. Hope that helps. Thanks !!
The people who made the app should add the Fenrir cause it is a Fjourdur creature its basically a big direwolf with a freezing ability and cool ice spikes when it happens you tame it like a direwolf tranq and feed it meat
