The best way to trap a wyvern is to use an argy with 200+ speed and above 2000 health. Be cautious of lightning wyverns and drag one wyvern at a time. Go for a low level female wyvern and use a trap made of pillars, ceilings and with a behemoth door that had a remote key pad attatched. Pin code works best as 1111 to trap and use tranq arrows as they are cheap and effective.
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.
