Argys with 10k health + 1K% dmg & 2k stamina will most of time no diff a wyvern trench.

Tame 2 145-150 Argys mate them until you have these stats and just take an extra argy with you to help fight and you will clean up the trench so you can loot the eggs without being chased or 1 shot.

( watch out for the poison wyvern they will kill you while on tame, and lighting at 145+ can do a lot of dmg so make sure you avoid that beam)

I recommend watching videos on how to aerial fight but I just spin counter to the dragon since it will make it use the bite instead of beam and I can usually hit 1-2 times before we spin again.
