The Snow Owl has the Ability to heal nearby tamed creatures, however, it uses up its stamina.
The Snow Owl works like the Argentavis, except it has a thermal vision as another one of its cool abilities. They also perform a dive just like the griffin as well!
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 -
