Absolutely fantastic mounts. Up their stamina a few times as well as their weight, and you've got yourself a fantastic globe-trotter. I use mine for getting supply drops at night. Put an otter on your neck for temperature regulation or a Jerboa as a backpack and you've got yourself a perfect world-traveling setup. Griffin's are absolutely fantastic 10/10.
i tamed a level 95 bad boi and these things SLAP. literally. their dive attack deals 280 damage per hit and you can hit creatures at least twice before swinging back up. immediately get your bonus for killing each creature for your first time and level up stamina, then take on an alpha carno. i got +14 levels from killing a level 90. just keep bumping stamina and weight!
