Unicorns are able to receive Medusa's Blood to give them wings. When a foal is born, wings will not be transmitted, to make the foal winged you will need to give them another Medusa's Blood. Also a winged unicorn has the same chance of producing a unicorn foal (1 in 5) as normal unicorns. They also have their own special category of golden apple coats like all other species. Because of the horses being both unicorns and having wings like a Pegasus, they have the combined bonuses of the two species. These bonuses are +3 in stamina, +4 in speed, and +19 in dressage.
