Hola! I decided not to use "hello" because it's an overused word, but I suppose 'Hola' would be overused as well if we went to Latin America or Spain or something.
Anyways, I have recently discovered that I love the cute little bird dragon mount thing I ride on, and I've created a mastery guide on how to treat it well.
You've gotten your new Griffon!
He is 10 feet tall, weighs a ton and is waiting for you to give him love and attention. Now because mounts are magic in this game, I really can't give you specifics. But a good thing to do would be to rub his belly and then bring him to some water. Elf water is his favorite.
But don't put him too close to the water! Or he will disappear for some random reason because he is magic, and that is my only explanation for it. Riding your mount can make it tired, be sure to take a rest every 9-10 hours.
That is all. I have no guide on your griffon, I am sorry, he is not complex at all.
PS: Someone said getting 10k dragon kills gives you a dragon mount, confirmation?
