Two people can ride and both can equip tools/guns while riding and can dive for help during combat too. These winged beasts sadly can't be bred because they don't have genders, much like the rock elementals. And you're going going to have a very hard time knocking one out considering they fly fast and have decent attack, but will most likely be worth it. Probably going to have to move to Ragnarok because of these things.
It's basic swipe from the ground is rather weak. It's strength comes from being able to dive swipe. To utilize this, you will want to focus the camera on your target and fly above then straight down at the enemy, while left clicking to swipe a claw in air. This does unreal massive damage, potentially thousands of damage.
Great for wyvern egg stealing, you need to master the dive acceleration before trying though. I recommend doing it over water to simulate the lava you would burn to death in if you fail ;)
Other than that with the dive these appear to be completely unmatched as far as speed goes for any Dino except maybe a pure speed galli
Griffins are the kings of the sky! Pump melee and stamina, health is probably a good thing to have until you get your technique down. Swoop down (look at the ground and sprint while in the air) and while in mid-swoop, attack! I have gotten dmg over 1.1k on a good dive. On top of the damage dealt, the AoE is pretty good too
Best dino in ark in my opinion. It can deal up to 1700 or more damage per hit depending how much melee you put on it. It kills rexes, brontos, gigas and all alphas really easily and safely. It harvests great and is fast too. Broken if you ask me.
