Get one high level Argy ( health weight and stamina focused ) and maybe 4-5 PT’s high or low level it doesn’t matter they are bait. This is a good technique for Ragnarok but it works good anywhere anyways just dive in find a egg then jump off the argy and get the egg. While on the ground whistle attack target to your PT’s towards a wyvern ( put argy on ignore whistle commands) then when the wyvern is distracted fly up and dive low and swerve between trees and rocks to slow the wyvern(s)down!! Hope this helps
