Winged demonic beasts are a rare form of demonic beasts, that have wings instead of front legs. This makes them difficult to deal with, due to their ability to, well, fly. They also seem to keep some intelligence, and where also used by the empire in the Serios war. Not much is known about what causes the transformation into a winged demonic beast instead of a normal demonic beast, but it has been theorized to be due to the crest stone's shape.
