WARNING: When raising one of these prior to hatching be sure to have at least 3 fridges full of meat because these babies are absolutely savage and eat around three to five meat at a time! Help spread the word!
Basically the product of an Argy (high weight and looks like one, minus the corrupted face), Daeodon (healing), and Griffin (dive attack). I would pick these over almost any Extinction creature, besides Velonasaur. And yes, this includes the Managarmr.
They can thermally detect any living thing around you giving a strong pvp advantage. Like a night vision with wings. Plus they can put you and your allies in stasis and heal you whilst being an ice cube. Decent airborne mount -
