Me and my friends got it with ease

Here's how .

What you need:1 griffin (with decent health) 1 fast flyer you don't care about (pteranadon recommended) and 3 people one with good armor

Method: have one person riding griffin and one on the back and have one person on the pteranadon (this is much easier if on non dedicated)

First the griffin Flys down to the nest the person on the back hops of and grabs the egg to ensure the survival of the rider. By this time you will have alot of wyverns on you. You then fly out of the trench with the wyverns following you that is when the pteranadon attacks the wyverns to get there attention if on non dedicated the griffin that the host should be riding the griffin then the griffin will get far away and Teleport the pteranadon to him if you are on dedicated or offical wing it

Hope this helped
