When diving (run while looking down in the air) when you pull up at the last second the griffin gains a ton of speed that slowly goes away or stops when you cancel the run. Good even for getting around on land.
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.
