quick tip to go faster with a Griffin. when diving, try landing slightly tilted, for some reason it carries the momentum you previously had, after landing, start flying a second. you’ll basically be slingshot though it only works maybe 50% of the time.
Wanna get Wyvern eggs? Use one of these with a whip and you'll get so many eggs you'll end up with so many omelettes that you don't know what to do with them
While diving pull up at the last second above your target and use main left click attack. Does a ton more dmg then just landing on target. Gives a nice speed boost too.
