imo these are the BEST flying mounts in the game because you can hold 2 people and shoot of of its back along with their maneuverability, speed, damage output, stamina, dive bomb, 2 special attacks, and health. I'm currently leveling up my griffin and so far it has 500% damage, 1500 stamina, and 15k health and there is practically nothing that can take it down. (also, its dive bomb swipe attack does over 1000 damage!)
This is a fantastic tame to get as soon as possible, they are one of the fastest flyers in the game and they also run fast too. They feel so nice to dive with, their attacks are pretty nice, when you want to turn just stop going fast and its turning circle becomes very small. They don’t use too much stamina too so you can spend those extra points elsewhere. They also allow you to shoot from their back making them one of the best dinos for your first Quetzal. Cheers!
