The best way is with two people a spotter and the driver. And your argy will need 200+ speed or if you are using a tapejara 240+ speed. You will also need a trap that your argy will be able to pass through but not a wyvern. Trap will need a key pad so you can close gate behind it. Crossbow will be the weapon you use and you will need to place the wyvern milk onto your tame along with preserving salts to make it last much longer . Last thing as soon as you knock out the female wyvern you will have to get the milk quick since it doesn't stay unconscious for to long.
I got a level 150 lightning egg and I was so excited to hatch the egg...that when I went to put the egg down I accidentally ate it instead. :( ps4 users: R2 ISN'T GONNA DROP THE EGG YOU'RE GONNA EAT IT LIKE ANY OTHER EGG. REMEMBER THIS. LOGIC BEFORE EXCITMENT.
