These things are GODS when trying to get somewhere fast in Ragnarok just fly high up and put some points in stamina and dive bomb down then pull up and you turn into the flash
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.
